Hydraulic press with your hands: the tool from the jack

Hydraulic press is widespread in everyday life. It is needed for jobs that require the provision of high pressure on the material being processed. High-quality multi-tool has a high cost, which is completely unjustified for domestic use. You can make a hydraulic press with their hands on the basis of the jack.

Purpose and scope of use of the hydraulic press

Hydraulic press is an apparatus that performs a lot of pressure on the material to be treated by a minor effort. Such principle of operation is based on Pascal's law, according to which the applied force on a certain area, is transmitted throughout and is equal in all directions.

The apparatus represented by two hydraulic press cylinders. When exposed to the lower chamber increases fluid pressure therein that is transmitted on a special channel in a large chamber. The piston has a working fluid pressure, thereby exposed element on the workpiece. Cylinders are generally arranged vertically, but there are embodiments having a horizontal placement. In special oil is used as working fluid.

This setting is used for pressing, stamping, extrusion, assembly, forging, bending, straightening metal elements. You can buy or run their own hands press board, which will be indispensable for packaging, briquetting, baling and recycling of materials from plastic, paper and rubber. The equipment is characterized by versatility and can be used in different spheres of life to carry out repairs, servicing and maintenance work. Depending on this, the press has a certain design concept.

Applications hydraulic press at home

For the extrusion of metal elements from the shell or base you can buy or make a hydraulic press with their hands in the garage. The equipment is also suitable for pressing out bearings and silent blocks that do not lend themselves to manual assembly and disassembly. By means of such a device can perform straightening, to dock the two elements to bend metallic workpiece.

Useful advice! In the manufacture of their own hands the press need to be defined with further devices of its size, performance piston weight and the ability to install a pressure gauge.

When creating a hydraulic press for the garage should consider the size of the car. For cars is enough to make a simple design, and for large machines better perform more complex and dimensional unit.

A device often used as media for waste paper. The hands of the old paper can make a good fuel for the furnace. For these purposes make simple structure with an average power sufficient to allow a large amount of recycle wastepaper.

The equipment is also suitable for compacting sawdust. These briquettes are good fuel for the stove heating, they burn for a long time without the formation of smoke, creating intense heat. Instead of sawdust as a filler for the press is also suitable Coal crumb. This unit will consist of a desktop, a base frame and a power actuator.

A good result provides created with their own hands for PET bottles press that turns container into neat layers. Hydraulic tool can be used as a pick-up hay. In this construction the rack is supplemented from timber or metal without the upper part. The element fixed to lobovine using special hardware. It will also need to transport the pickup and chassis part.

Design of an improvised press ram

Before you make the hands hydraulic press, you should understand what the constituent elements included in its design.

For the stability of the device requires robust and reliable lower portion which serves as the unit base. It has the look and the platform is made of a thick massive metal-roll. For this are advantageously used channels and the corners of the metal.

As can be seen from the scheme of the press, vertical uprights of the structure are presented. The elements are made of steel and welded to the corners of the base so that the right angle was provided between the elements. The height of the rack is computed as the sum of the height of the jack, the length of its stem and the thickness of the workpiece. The upper part is fixed racks fixed stopper. For its production using corner.

To create the necessary efforts on the work surface is used a hydraulic jack. It must be mounted on a movable stop. The jack is actuated using a manual lever or actuator.

The movable abutment pressure on the next pressing mechanism. The element is made of steel strips or corners. To move all the way to the normal position used reengaging. It is represented by several springs. Their length and the stretching ratio are calculated from the parameters of the press.

Homemade press apparatus for garages: design characteristic

Before making hydraulic press, should determine the type of installation. Depending on this equipment may be a desktop or floor. The first type of tool is located on the bench, while the second is placed on a pedestal. Such media are different dimensions, load-carrying capacity. Made by hand hydraulic press table provides a force of up to 12 tons, and it reaches a value of 25 tonnes for the outdoor unit.

Table design is more stable, mobile. Due to its small size, it does not take much space. Such a press is used for treatment of small workpieces.

Floor hydraulic press is characterized by large size and heavy weight. To install it will need a special construction of the platform. Such a machine will cope with the processing of large items from metal, assembling and disassembling complex units.

Important! To extend the functionality of the floor of a hydraulic press should be staffed with an electric motor.

You can make a complex structure, which will be used for a wide range of applications. However, the manufacture of such an option will take time and will require the use of specialized tools and equipment. As the garage of a hydraulic press is better to make a manual model equipped with a hydraulic pump and drive. This design is a two-speed, characterized by its piston mobility.

Made with his own hands a hydraulic press for the garage can be horizontal or vertical version. The first type of apparatus used for straightening, cutting and bending the individual elements of metal. Vertical equipment is designed for the breakup and insertion components. Made by hand hydraulic press for waste paper is becoming increasingly popular.

Features create with their own hands the hydraulic press

Homemade structure must perform the required task list. Suffice it to a device that produces a force of 15-25 tons. For its production need to prepare a working drawing of a hydraulic press with his hands from the jack with the dimensions of structural elements (such circuit can be found on the Internet). It should take into account the type of tool that can be fixed or removable, dimensions of the product of the piston stroke and the design of the frame.

A hydraulic working cylinder is located separately or integrated into the structure. Thus it can be in the top or bottom. In the case of the first embodiment will be pressure on the lower surface of the base. If the operating element is arranged on the frame at the bottom, the pressure will be directed upwards as a result of primary rod.

As the hydraulic cylinder applies a jack, which acts as the main operation member. It should be borne in mind that the tool can be presented in different versions. Therefore, when choosing the jack is necessary to determine for what purpose will be used by the press and allow the maximum force adjustment.

However, it should be remembered that the industrial bottle-type tool will not function in an inverted state. Therefore, before a press of the jack, you need to finish the product. The design must provide for the installation slot, which will be in contact with the cylinder rod. For its production need to use a length of pipe.

The material for the frame is selected with a safety margin that will prevent damage to the frame while providing the highest possible force. After the task of processing the preform rod must return to its original position. To do this, choose the right spring on the basis of the degree of hardness, so that they can be effectively fulfill its purpose. Their edges are attached to movable upper and a fixed lower base parts.

Designing self-made hydraulic press for the garage with his hands

After selecting the jack should start designing the frame, which will put pressure cylinder. To do this, create a drawing of the hydraulic press with your hands. And the size of it are applied to each individual element devices. The design must be durable, because during operation the jack will provide pressure on it both downwards and upwards, trying to break the frame.

The base should ensure the stability of the equipment, the best solution is its implementation as a platform. table width is determined based on the size of the product to be processed on the press. However, it should not be less than the total width of all elements of the press equipment.

The height of the frame is calculated as the sum of the dimensions of the jack, the values ​​of free movement of the rod, the height intended for machining and the thickness of the mobile working platform.

The jack is attached to the base. Focus product performs frame top. By means of sliding table is performed on the pressure transmission part. The surface is fitted over the jack on the base frame, on which it freely moves up and down with the fixation on each side.

To ensure free movement of the adjustment rod of the jack can install replaceable insert-lining of a solid or hollow metal profile. Another option is to perform a removable abutment in the form of a desktop, which moves. It should be fixed to the frame using nuts and bolts or rods. To do this, make holes in the frame height of less than the range of movement of the jack rod.

Another solution is to create a so-called screw press with their hands using the drive with the steering wheel. Reduce the clearance for the workpiece within the frame can be by twisting screw cooker.

Useful advice! For free movement of control rod is best to use a combination of several of the above options.

The sequence of manufacturing their own hands of the press ram

Before you make with your own hands the press, it is necessary to prepare the welder electrodes, grinders, drill and drill. For finishing of metal structural elements of burrs need sander. In a first step the frame is going to press. From its strength and reliability depends on the quality and efficiency of the workflow. The frame will be located slave cylinder (in the form of a ram), and the workpiece.

The material for the frame, and its constructive execution variant assembly determined based on the sensed pressure of the jack. Referring to the drawing press with their hands, base unit represented by the U-shaped rectangular frame of channel or angle steel weld. The main effort will be concentrated in the central part of the horizontal bars. Achieve the maximum possible stability of the structure is obtained by welding it to the base metal plate 08-1,2 cm thick.

Design and operation of the tool. The types of devices. Areas of use of a hydraulic press. Rules of selection and operation.

For the manufacture of the frame installation, designed for forces up to 5 tons, it needs to channel size 8P and two hot corner 50x50 mm, which are connected to solid weld or associated rods every 25 cm. If the instrument will take the effort of up to 10 tons, to the frame you want to channel 10P and paired corners size 63h7 mm. For the manufacture of the press with the necessary compression force of 15 tons and above, use channel 14P and coaxial Area size 75h8 mm.

Important! The bed of metal of the above will have a tenfold safety factor that will contribute to the normal operation of the device - the frame without destruction.

Cusp press frame for the garage with his hands

All elements of the carcass are interconnected according to the drawing the hydraulic press. First going basis, then - the side portions and the upper frame bracket. It is important to monitor compliance with geometricity design, in which all the elements have to be a party of the right angle.

Docking takes place by means of weld seams solid bilateral abutment with trimming products. An alternative is to use the fingers or cotter-pin bolts for the assembly of parts. It should take into account the maximum load per slice. With this connection, the main load will be concentrated on the bolt connections. Therefore, it is important to correctly calculate their number.

Next, you manufacture the travel bar to the hydraulic press of forging their own hands. For this purpose a square pipe or channel. In its central part a pipe section is welded, which will further serve jack rod. The guides are made of two steel strips, the length of which must be equal to the width of the outer casing. The elements are attached with screws to the side uprights mobile design.

Likewise made removable abutment. In its guide parts necessary to make holes for adjusting the height of the working space. In the final phase, the installation of the jack and springs.

How to convert ram to press to make it work upside down

The most affordable option, which is used as a hydraulic cylinder for the hand press with your hands, is a jack of bottle type. The main problem of such a tool is the inability to operate in the inverted position. In this case, the instrument can be mounted on the upper beam is stationary. In this case the lower base is used as a support member. Before you make with your hands press, need to perform revision of the hydraulic mechanism.

There are several options jack alterations that can be used in the assembly of a self-made hydraulic press. The first is the additional installation of the expansion tank volume of 300 ml. Capacitance to be connected to a filling hole of the jack by applying a conventional silicone tube. The element firmly seated, you must use the connections for oxygen hose, which can be purchased at any auto parts store.

The second option involves the alteration of the jack disassembly tool. To do this, it must be completely drain the oil and perform a pumping plunger. Further twisted upper presser nut by clamping it in the vise. Then it is necessary to shatter the outer glass with a rubber mallet. An element to be released from the bead seat, which is located at the base of the jack.

After the plunger lever is a hole for intake of the liquid. With incomplete filling of the cup in his upside-down opening is not in contact with the oil. This is a major problem when using a jack for an improvised press. It can be solved by means of a tube, which should drive in the entire length of the cup.

The jack can be left in its original version. However, to ensure design performance will need the installation of additional third beam. It is secured to the side walls tight enough that promotes the stationary position of the jack when creating pressure. The tool is fixed in the inverted position to the central portion of the upper beam by means M8 or M10.

How to make the press: manufacture and installation of clamping pads

To work with large workpieces need a large area of ​​compression beams. The stem of the jack in this case does not provide this, since the implementation of the pressing force must evenly distributed across the surface of the treated area, preventing the formation of deformations.

As the clamping pad to be created with their own hands the hydraulic press can be used for a garage full-bodied pig, which perform blind threaded holes, whereby the elements fixed to the structure press.

The best option is an independent manufacturer of shoes for the press with the jack by hand. To do this, you can buy four pieces of metal bracket or two channel bars. With the help of the elements creates a box with the open side faces. Butt sites that accept the main effort should be brewed inside a continuous weld. Other places are welded from outside.

One of the faces must square muffle insert, and an inner cavity pour concrete solution M500. After solidification of strip solution is sealed on the other side. Thus, a two incompressible element.

To the top board is fastened to the rod jack. For this is done blind bore, which is inserted into the heel of the tool with minimal clearance. There are also openings are made for fixing of the return spring mechanism. The lower block is attached to the adjustable beam. For greater reliability and slide limitation it is welded over the pair of metal rods.

Installing the adjustable support bar return mechanism for the self-made hydraulic press

The lower and upper beams must have the same cross section. Different elements of a constructive implementation. To perform the lower support member are two channel, be drawn to the outside edges. They must be applied on opposite sides relative to and welded to the uprights of the central part thereof by applying inserts from corners or thick reinforcement.

Fixing on the posts of the beam is carried out through the use of massive steel fingers. Under them should perform a series of circular cross-section punchings at different heights in a parallel vertical channel bars. The diameter of the holes must comply with the cross section of the bolts.

Another design element made with their own hands Garage is a hydraulic press a spring mechanism, whereby the jack returns to its original position when the bypass opening valve. To do this, fit just spring for finishing doors, which can be purchased at a hardware store.

Complicating the task of the upper pressure plates, which has a considerable weight, so that the spring can not be compressed. Out of the situation can be achieved by increasing the number of spring elements to 4-6 pc. That is acceptable to make the hands of the hydraulic press table. You can also use the more powerful elements for the door, which is more relevant for outdoor installations.

If the upper block is not available, the springs are attached to the stem of the jack. Fixing is performed by means of a washer, which has an inner bore larger than the adjusting screw rod but smaller than the diameter of the piston. The spring must be secured by means of two small extreme latching apertures to the upper beam in the same manner. The spring may not be installed vertically. Surplus length element can be compensated for its inclined position.

Useful advice! For fixing the spring can also be used welded hooks.

Features of creation of hydraulic oil press with their hands

Made by hand homemade press of the jack can be used as a device for the extraction of oil. However, during manufacturing is necessary to provide some design features.

The upper frame crossbeam required to fix the metal plate. It should be easy to move on the rails under the action of the screw shaft. Such a mechanism makes it possible to control the gap between the pressure pad and the material being processed.

For fixing a removable mobile pad improvised press of jack screws are used. They are installed in pre-created hole with a certain step, which is determined by the terms of workflow. However, the distance between the holes should be no greater than the free movement of the hydraulic ram rod. Clamping elements are made of metal of different thickness and are removable. According to this technology, you can also press to make paper by hand.

Useful advice! Fixing the clamping beam to the guide can be done with the fingers of durable metal, the diameter of which is selected based on the size of the casing and applied force during operation device.

How to use a hydraulic jack: Design Features

Most often made homemade press of a hydraulic jack. This is due to the design of the product and how it works, which is based on the laws of hydraulics.

a piston located in the cylinder of the jack. Above or in a separate tank is the working fluid in the form of mineral oil. Hydraulic jack actuated by means of a small pump, which pumps oil through the relief valve above the piston. Stress is minimized due to the difference of the plunger diameters and the tool cylinder. The working fluid, which is located above the piston, pushes it, thereby lifting the load, which is located above it.

To lower the instrument, you should know how to use a hydraulic jack. To do this slowly bleed the working oil from the piston to the tank or the top of the cylinder. For this purpose a bypass valve in the form of round head and shoulders to be weakened.

In operation, there may be some difficulties that occur due to insufficient oil level in the device. For troubleshooting, it is important to know how to fill the hydraulic jack with his hands. For this it is necessary to unscrew the filler plug on the tool body and insert into the hole a hose for filling the reservoir until the desired volume. Upon completion of the process by pumping the jack.

Features created with their own hands the electro-hydraulic press

Independently can be made not only manual hydraulic press, but also a device equipped with an electric drive. Such a device is able to develop a huge effort that extends the functionality of the equipment and increases its efficiency.

The operating principle of the hydraulic press created with their own hands with the electric drive is as follows. The hydraulic pump is driven by a motor which is connected to the mains. In turn, the hydraulic pump contributes to maintaining the necessary hydraulic fluid pressure in the first press chamber. The piston transmits the pressure in the second reservoir press where it increases several times. Thus, the resulting force is transmitted from the second cylinder on the processed material.

Important! The magnitude of transmitted force to the workpiece will depend on the ratio of the areas of the pistons in both cylinders.

With the electric motor can be set up as a floor and table hydraulic press with your hands. Both versions will be different in size and value of the force exerted on the workpiece. For desktop devices does not exceed 20 tonnes, and for floor - 100 tons.

Hydraulic press with your hands with an electric motor

Production of devices starts with performing a drawing hydraulic press with your hands to the application of all design elements and an indication of their size.

Frame design to withstand heavy loads, so it must be made of durable material. The best solution is to use a tee that will not bend under a hydraulic press.

Frame shows a U-shaped bed, which is set on the basis of the more delicate parts or U-sections. In the central part of the frame height must be welded to establish a working platform of the thick-wall channel bars.

The next step in the manufacture of home-made hydraulic press with your hands is the installation on the cylinder frame, which is performed in a certain sequence. To ensure secure attachment of the hydraulic pump should be fixed on the metal plate by using a flange. The back plate is mounted on the I-frame beams.

The flange may be made of automotive hubs, treating it on a lathe. The metal plate for installation of the hydraulic cylinder necessary to weld a circular boss for fixing the lathe chuck. After boring the hole plate is welded to the base frame.

On the cylinder flange is worn with the necessary planting hole and scald in a circle. For reliability of the device is required to manufacture and fix to the upper portion of the other flange of the hydraulic cylinder, it is welded to the beams.

Important! The flange and the cylinder must be welded to each other smoothly as possible, so the surface of the first pre-processed in a lathe.

The metal plate with welded beams fixed to the frame by welding. It carried out the holes for the fixing bolts. To ensure normal operation of the press should be installed oil station, connecting to the cylinder by using a hose.

Repair of hydraulic press ram with his hands

To maintain the long-term operability of the hydraulic press is performed on the basis of the jack, an improvised device needs to properly operate and maintain. In the process, you need to monitor the level of oil in the hydraulic cylinder, lubricate moving parts, check condition of sealing compounds, secure fitting assembly elements.

However, any mechanism may fail to work, which is the cause of incorrect operation or wear of individual design elements. If you created your own hands garage hydraulic press stopped or does not start, check the oil level in the hydraulic cylinder. When it is required to perform insufficient filling of the container with the subsequent pumping jack.

If there is a leakage of fluid, this indicates a mechanical failure or damage to the structure of its individual elements. In order to eliminate the defect is necessary to disassemble the jack, check all parts for the absence of corrosion damage. The rod is inspected for deformation. Damaged components should be replaced by new ones. Working oil must be drained completely. The inner cavity of the jack and all its elements kerosene washed and dried. Old gaskets and seals need to be replaced with new ones.

Other problems when work is done with his own hands the press of a hydraulic cylinder

If there is an insufficient level of effort of manual hydraulic press, made with his own hands, or the mechanism works intermittently, this problem is related to the possibility of falling into the cavity of the air jack that has a negative impact on the piston. To eliminate damage to the cylinder should be added to the working fluid by removing air through the ducts.

Low pressure valve mechanism explained damage which departed from compartment, dirty or it springs loose. In the first two cases, a repair or replacement of the item. Purification of the valve is performed with a damp cloth followed by drying element. In case of heavy contamination mechanism washed with kerosene or petrol and dried with compressed air. If the reason lies in the deterioration of the spring, they must be exchanged for new items.

Important! If the jack is damaged casing or piston requires a complete replacement of a mechanism that can not be repaired.

After dismantling the jack to carry out repairs mechanism is required to collect on certain conditions. The valves must fit snugly to the seats. It is necessary that in the hydraulic cylinder was a sufficient amount of liquid. In the air there should be no system.

Hydraulic press is a multi-purpose equipment that can be used for different tasks where you need to make an effort. The tool can be purchased at a specialty store or make the press with their hands from a hydraulic jack, which will save finances. To do this, it is important to select the material and stick algorithm assembly elements.
