Rolling of profile pipes in industrial conditions
Bending metal pipes at the desired angle or a given contour, preferably without loss of strength properties and internal working sections is quite often. In piping systems - an excellent opportunity to do without unnecessary connecting parts, in structural structures from profile pipes - a certain freedom of design and design thought.
We have specially introduced this section to slightly cool the natural ardor of our fellow citizens to do everything by our own hands: handicraft mechanical or hydraulic pipe benders, rollers for it from random metal pipes, and spoiled metal rolling - entertainment, certainly worthy for a real man, but easier to look forfinished profile products, which you just need to bring to the condition.
For people far from such mundane topics, we will explain:
A bending machine is a mechanical device that can bend pipes of any size and configuration. There are only three variants of industrial design by drive type:
- manual: the simplest in principle and complicated in operation;The template of the final deflection of the pipe can be changed, but the physical effort to perform the shaped work remains equally large;
- hydraulic: a variant of a semi-professional pipe bender with rolls of alloy steel, which allows rolling of pipe profile rolling up to 80 mm without loss of strength properties of pipes, knocks and stretching of the working section;
- electromechanical: industrial machining production, on which the majority of ready-made constructions made of tubular products are produced.
The rollers of the pipe bender are just two round in the cross section of the shaft made of high-strength material, between which the material being processed( in our case, an ordinary steel steel pipe), which takes on a predetermined shape, "rolls".
Make pipe benders with your own hands or buy a ready
The question is ridiculous, since it affects two absolutely different areas: financial and psychological. Many of our compatriots find it easier to buy a finished pipe bender, not to suffer with the calculation of rolls and loads, but simply take the instructions and quickly bend all the pipes that are available on the countryside.
The most important question that always comes up when buying expensive equipment is the price. For reference, we will inform you: a high-quality hydraulic pipe bender is in the range of 22-35 thousand rubles. Perhaps all of your, erected from curved profile pipes, the structure( canopy, garage, summer kitchen) are priced cheaper. A hand-bending device with six bending profiles and a jack-rod pull will cost 9500-12000 rubles.
Agree, if you do not plan to build up all your lands with openwork greenhouses and arbours of complex architectural forms, then such expenses for equipment are clearly superfluous. Our natural estimate starts to work and, as a result, the traditional Russian answer: we will do it ourselves.
How to make a pipe bender for a profile pipe with our own hands
We considered the entire range of profiled steel pipes, their design advantages and scope of application separately. Now we will try to bend our hands on a given radius of the final product.
It is very important to avoid the following technical defects:
- cracking;such a metal profile will have to be thrown away;
- compression or stretching of surfaces at points of potential load on the structural element;
- deformation of the initial profile, leading to a violation of the resistance of the metal( corrosive and mechanical) in the bending and fracturing nodes of the supporting structure.
If you are ready to perform an assembly and rollers for your own work with your own hands - honor you and praise. The simplest artisanal bender with rolling rolls from the electric drive( any electric motor with a reducer is suitable) and a clamping device made of ordinary steel pipe. It is mounted on an ordinary car jack and, judging by the reviews, it gives quality arched products.
We appreciate the technical findings of our "kulibinyh", but we recommend buying ready-made rolled metal of any configuration or making it to order according to your drawings and ideas, especially without bothering your hands and head.
