The pipe bender bends the tube and bends the sheet. In the case of pure bending, when the outer diameter is d and the wall thickness is T, the outer wall of the neutral layer is σ1 by tensile stress and the tube wall becomes thinner, the inner wall of the neutral layer is σ1 by tensile stress and the wall thickens. Moreover, the cross-section of the shape due to the resultant force F1 and F2 of the action from the circle into an approximate ellipse, Pipe Bending Machine when the deformation is too large, the outer wall will produce cracks, the inner wall will appear wrinkled.
The degree of deformation of the tube depends on the relative bending radius/and the relative thickness of the t/d value. The smaller the/and T/D values, the greater the degree of distortion. In order to ensure the forming quality of pipe fittings, the deformation degree must be controlled within the permissible range, Pipe Bending Machine and the bending limit of the pipe is not only dependent on the mechanical properties and bending methods of the material, but also the requirements of the pipe fittings. The forming limit of the pipe fitting should contain the following contents:
1 The maximum elongation deformation in the lateral tensile deformation zone of the neutral layer does not exceed the plastic allowable value of the material, Pipe Bending Machine and the rupture occurs;
2 in the inner compression deformation zone of the neutral layer, the thin-walled structure which is subjected to tangential compressive stress does not exceed the instability and wrinkles;
3 If the fitting has the Ellipse degree request, controls its section to produce the distortion;
Pipe Bender is mainly used in power construction, Pipe Bending Machine public railway construction, boilers, bridges, ships, furniture, decoration and other aspects of pipeline laying and building, with many functions, reasonable structure, simple operation and so on. Bending machine can be divided into CNC pipe bending machine, hydraulic pipe bender and so on.
Characteristics of the pipe bender structure:
1, the pipe Bender uses the touch screen to add the numerical control module, Pipe Bending Machine the dialogue type operation, the program setting is easy;
2, the bed structure is stable, not easy to deform;
3, each file can be set 16 bending angle, memory can be stored 16 sets of files;
4, the slow-speed positioning function, bending angle stability, repeated accuracy of ±0.1°.
5, the error message is displayed on the screen, help the operator to eliminate immediately;
6, to provide their own research and development of the coordinates of the conversion of pipe processing value, software can be purchased on the desktop computer editing calculation.
