Learning to make pipe bending machine

Roller bending machine can be a product which is about the technology of mechanics of material, elastic-plastic along with control technology. This article will introduce the structure on the roller bending machine in detail to enable you to know how it is produced.

Components on the pipe bending machine

• The rocker arm, its function is to make sure that the bending radius from the elbow meets the requirements, and its clamping seat is to limit the rebound belonging to the steel pipe during that tube bending process.

• The pumping station will be divided into two segments: high pressure and low pressure to supply power for the opening and closing with the guide roller, the rocker limb clamping seat cylinder, the opening and closing from the trolley chuck of this pushing device, and the opening and closing from the straightening roller.
  

• The guide roller device consists of two groups of guide rollers, a frame and also a clamping transmission system. The opening and closing with the guide roller is done by hydraulic drive, and its function could be to complete the horizontal bending in the steel pipe alongside the rocker arm.
  

• The driving device is the power source of the actual pushing device.
  

• Styling roller. It prevents vertical deformation through bending process, and is used together with a floating anti-ellipse fixture to ensure the ellipticity of that steel pipe after bending meets the requirements.
  

• The pushing device (consisting belonging to the trolley, bed, drive shaft, traction chain, etc. ) shoves the steel pipe frontward, and the steel water pipe is bent under the action belonging to the rocker arm and your guide roller.

Technical issues with pipe bender

The bending machine performs the bending on the pipe and the bending on the sheet. In the case of pure bending, 2 tube with an surface diameter of D plus a wall thickness of big t is bent under the action of the external moment M, the outer tube wall belonging to the neutral layer is afflicted by tensile stress σ1, and also the tube wall becomes thinner; the inner tube in the neutral layer The wall is put through tensile stress σ1, as well as the pipe wall becomes heavier. Moreover, the cross-sectional shape changes at a circular shape to a strong approximately elliptical shape with the combined forces F1 plus F2. When the deformation is too large, cracks will occur for the outer tube wall and wrinkles around the inner tube wall.

Their education of deformation of the pipe bender is determined by the relative bending radius R/D as well as the relative thickness t/D. The smaller the worthiness of R/D and t/D, the greater the degree of deformation. As a way to ensure the quality regarding pipe fittings, the amount of deformation must be controlled while in the allowable range. The bending limit of pipes not merely depends on the mechanical properties from the material and the bending method, but also considers a use requirements of the pipe.

Bending principle of pipe bender

The bending principle with the pipe bender, under natural circumstances, has the following two situations, namely retract bending and winding.

Both have their positives and negatives:

The winding type is principally used for the bending of square pipes as well as its structure is intricate, while the roll bending type is mainly used for the twisting of round pipes and can even be used for square water line bending but not just like the winding type, even so the structure is simple. Consequently, the steel bending equipment adopts the roll bending type.

The steps regarding bending the pipe are usually roughly:

• Leave along the first straight segment and clamp the pipe.

• Bending.
  

• Loosen your clamping block, take away the tube, and reset the mold. Check the tube shape within the inspection fixture according to the tube shape standard test and correct it.
  

• Repeat step 1 till the pipe is bias.

Zhangjiagang King-Macc Machinery Creation Company can provides the particular satisfied tube bending for the customers according to the accumulated designing experience and many more experiments.
