On earth do you really know pipe twisting machine?

Pipe bending machine is known for a very wide range associated with applications on metal structure, agricultural machinery, power systems, as well as boilers, petrochemical, electric powered power, light industry, along with other industrial sectors. With that rapid development of economic construction, the number of many tube bending machine and forming pipe fittings, technical specs and material requirements are constantly increasing, the patterns continue to renovate, while the precision and surface quality from the pipe bender put send higher requirements. This feature is mainly prominent in certain industries for example power systems.

Pipe bending machines processing methods

Roller bending machine processing method is quite a bit, according to the twisting method, it can become divided into rounding, press bending, pressure bending in addition to roll bending; bending with or without filler can be divided into core (filler) bending and no core (filler) bending; bending if or not heating can be split into cold bending along with hot bending.

Cold bending method incorporates a long history of improvement, more types, while the hot bending method is merely developed in the previous two decades bending processing methods. The main pipe cold roll-forming processing approaches are:

• pressure twisting;
  

• wrapping bending;
  

• rotary die bending;
  

• pull bending;
  

• move bending;
  

• push bending and other forming methods.
  

The qualities of roller bending device

In addition, there tend to be expansion tube bending, vibration as well as impact bending, wrinkle bending, MOS bending and different bending processing methods, but generally not common. In the actual pipe cold bending process, rotary die bending (or rotary catch the attention of bending radial-draw bending) may be the most common bending control methods, but also the use of CNC pipe bending unit bending processing. The tube forming process discussed during this paper is under this bending process method of research.

Compared with solid plate bending, the pipe is hollow thin-walled structure belonging to the cross-sectional shape, the stress-strain state analysis is so visible, the pipe in the particular bending process, the neutral layer outdoors the tensile stress and thinning of the pipe wall, the neutral layer inside compressive stress and thickening from the pipe wall, while the particular pipe cross-sectional distortion, that is, flattening. Therefore, no matter type bending method is taken, in the pipe bender progression, easy to produce the next kinds of adverse phenomena:

• pipe bending outside the house the thinning, or actually cracking;
  

• conduit bender inner thickening, as well as unstable wrinkling;
  

• tube section distortion (flattening), or maybe deflated.

• Moveover, as the actual pipe bending is elastic-plastic deformation, once the load is removed, your pipe bender angle and also bending. Radius will arise elastic recovery, that can be, springback phenomenon; at duration, in the bending course of action, the pipe is be more responsive to tensile stress. At the same time, in the bending method, the pipe is afflicted by tensile stress. and make elongation, that is, elongation way.

• Factors affecting the bending process-ability in the pipe

• All these phenomena not only affect the pipe twisting accuracy, but also find out the steel bending machinability (i. at the. the pipe bending canning limit).

• There are a considerable amount of factors that affect your pipe bending machinability, which might be summarized as follows:

• pipe bending unit shape parameters, including diameter, wall thickness, bending radius, cross-sectional pattern, etc.;

• Water line characteristics, including yield strain, ultimate stress, elastic modulus, solidity, poor work hardening listing, anisotropic parameters, etc.
  

• The accuracy from the tube itself, such because country, uneven wall thickness on the spoon hook degree;
  

• the machining process, the manner of machining:
  

• bender, design and size of "bend" in addition to "core" communicator;
  

• cavity slippage condition belonging to the cavity, etc:
  

• the working temperature in the machined portions.
  

which can be a, b), c) the popular material parameters, d), e), f), g) the regular machining conditions.

At the present time the development of the curved tube bending machine should develop in the direction of the economy direction, heavy medium of heavy should be to control the independent wise property right.
