Cause of deformation degree of pipe bending machine

The deformation level of the bending pipe depends on the value of r / d and the relative bending radius r / d and the relative thickness t / d.For the forming quality of the wrapped pipe fittings, the deformation level must be controlled within the allowable category, the pipe bending forming but depends on the mechanical properties and bending essentials of the material material, and the utilization requirements of the pipe fittings. The reasons for the deformation degree of pipe bending machine are as follows:

1) Large elongation deformation in the outer tensile deformation area of the neutral layer without plastic tolerance value and crushing.

2) In the compression deformation area inside the neutral layer, the thin wall layout department affected by tangential compressive stress does not fail and wrinkle.

3) If the bending pipe assembly has ellipticity requirements, control its section distortion. 4) If the strength of the internal pressure, control the forming of the wall thickness.
