Roller bending machine is usually a product which is focused on the technology of technicians of material, elastic-plastic plus control technology. This article will introduce the structure with the roller bending machine in detail to be able to know how it will be produced.
Components of the particular pipe bending machine
Technical aspects of pipe bender
Bending rule of pipe bender
The rocker arm, its function is to ensure the bending radius belonging to the elbow meets the specifications, and its clamping seat would be to limit the rebound belonging to the steel pipe during this tube bending process.
The pumping station is usually divided into two components: high pressure and low pressure to produce power for the opening and closing with the guide roller, the rocker equip clamping seat cylinder, the opening and closing in the trolley chuck of the actual pushing device, and the opening and closing of the straightening roller.
The guide roller device consists of two groups involving guide rollers, a frame including a clamping transmission system. The opening and closing belonging to the guide roller is concluded by hydraulic drive, and its function would be to complete the horizontal bending from the steel pipe with the rocker arm.
The driving device may be the power source of that pushing device.
Straightening roller. It prevents vertical deformation during the bending process, and is used together with a floating anti-ellipse fixture to make certain the ellipticity of the particular steel pipe after bending meets what's needed.
The pushing device (consisting of the trolley, bed, drive the whole length, traction chain, etc. ) forces the steel pipe ahead, and the steel water pipe is bent under the action belonging to the rocker arm and your guide roller.
The bending machine performs the bending on the pipe and the bending in the sheet. In the situation of pure bending, when a tube with an exterior diameter of D including a wall thickness of capital t is bent under the action of the external moment M, the outer tube wall in the neutral layer is subjected to tensile stress σ1, along with the tube wall becomes slimmer; the inner tube in the neutral layer The wall is put through tensile stress σ1, plus the pipe wall becomes heavier. Moreover, the cross-sectional shape changes coming from a circular shape to the approximately elliptical shape because of the combined forces F1 plus F2. When the deformation is too large, cracks will occur on the outer tube wall and wrinkles on the inner tube wall.
Their education of deformation of the pipe bender depends upon the relative bending radius R/D as well as the relative thickness t/D. The smaller internet of R/D and t/D, the greater the degree of deformation. So that they can ensure the quality connected with pipe fittings, the penetration of deformation must be controlled in the allowable range. The bending limit of pipes not simply depends on the mechanical properties belonging to the material and the bending method, but also considers use requirements of the water line.
The bending principle belonging to the pipe bender, under typical circumstances, has the subsequent two situations, namely retract bending and winding.
Both have their positives and negatives:
The winding type is principally used for the twisting of square pipes plus its structure is complicated, while the roll bending type is especially used for the twisting of round pipes and can also be used for square water line bending but not as good as the winding type, nevertheless the structure is simple. Consequently, the steel bending device adopts the roll bending type.
The steps regarding bending the pipe tend to be roughly:
Leave along the first straight section and clamp the water line.
Bending.
Loosen that clamping block, take available the tube, and recast the mold. Check the tube shape for the inspection fixture according to the tube shape standard test and correct it.
Repeat step 1 right until the pipe is curved.
Zhangjiagang King-Macc Machinery Producing Company can provides that satisfied tube bending towards customers according to your accumulated designing experience and more experiments.
