Can you really know pipe bending machine?

Pipe bending machine is known for a very wide range with applications on metal construction, agricultural machinery, power devices, as well as boilers, petrochemical, energy power, light industry, as well as other industrial sectors. With this rapid development of fiscal construction, the number of a number of tube bending machine along with forming pipe fittings, specs and material requirements will be constantly increasing, the patterns continue to keep renovate, while the precision and surface quality from the pipe bender put ahead higher requirements. This feature is specially prominent in certain industries for example power systems.

Pipe bending machine processing methods

Roller bending machine processing method is rather a lot, according to the twisting method, it can end up being divided into rounding, motivate bending, pressure bending and also roll bending; bending with or without filler could be divided into core (filler) bending and no core (filler) bending; bending whether heating can be broken down into cold bending plus hot bending.

Cold bending method carries a long history of progress, more types, while the hot bending method should be only developed in the very last two decades bending refinement methods. The main pipe cold roll-forming processing procedures are:

1. pressure bending;
   

2. wrapping bending;
   

3. rotary die twisting;
   

4. pull bending;
   

5. retract bending;
   

6. push bending and various forming methods.
   

The qualities of roller bending machine

In addition, there are usually expansion tube bending, vibration plus impact bending, wrinkle twisting, MOS bending and alternative bending processing methods, but generally not common. In the actual tv cold bending process, rotary die bending (or rotary draw bending radial-draw bending) could be the most common bending digesting methods, but also having CNC pipe bending equipment bending processing. The tube forming process discussed with this paper is under this bending process method of research.

Compared with strong plate bending, the pipe is hollow thin-walled structure in the cross-sectional shape, the stress-strain state analysis is seen, the pipe in your bending process, the neutral layer exterior the tensile stress and thinning from the pipe wall, the neutral layer included in the compressive stress and thickening belonging to the pipe wall, while your pipe cross-sectional distortion, that is certainly, flattening. Therefore, no matter which kind of bending method is used, in the pipe bender progression, easy to produce these kinds of adverse phenomena:

1. pipe bending in the garden the thinning, or also cracking;
   

2. Tube bender inner thickening, or maybe unstable wrinkling;
   

3. pipe section distortion (flattening), or deflated.

Moveover, as the particular pipe bending is elastic-plastic deformation, when the load is removed, the particular pipe bender angle and also bending. Radius will manifest elastic recovery, that is actually, springback phenomenon; at the same time, in the bending process, the pipe is be subject to tensile stress. At duration, in the bending method, the pipe is afflicted by tensile stress. and make elongation, that is, elongation happening.

Factors affecting the bending process-ability in the pipe

All these phenomena not only affect the pipe bending accuracy, but also establish the steel bending machinability (i. e. the pipe bending digesting limit).

There are various factors that affect that pipe bending machinability, which have been summarized as follows:

1. pipe bending device shape parameters, including size, wall thickness, bending radius, cross-sectional condition, etc.;

2. Tube characteristics, including yield pressure, ultimate stress, elastic modulus, solidity, poor work hardening catalog, anisotropic parameters, etc.
   

3. The accuracy on the tube itself, such because country, uneven wall thickness in the spoon hook degree;
   

4. the machining process, the technique of machining:
   

5. bender, shape and size of "bend" plus "core" communicator;
   

6. cavity slippage condition belonging to the cavity, etc:
   

7. the working temperature from the machined portions.
   

which really are a, b), c) the frequent material parameters, d), e), f), g) the common machining conditions.

At the present time the introduction of the curved tube bending machine should develop for the economy direction, heavy medium of heavy should be to control the independent brilliant property right.
