Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe bending machines, and in particular to an anti-wrinkle mold inclined support mechanism for pipe bending machines. Background Technology
[0002] During the pipe bending process, when the pipe is formed around the bending die, the material on the outer side of the bend is stretched. Thin-walled pipes or pipes with large radii are prone to instability and wrinkling when bent. The function of the anti-wrinkle die is to stick tightly to the outer side of the pipe and provide strong reverse support (pressure), physically "pressing" the outer wall of the pipe to prevent it from bulging and deforming to form wrinkles.
[0003] The anti-wrinkle die inclined support can provide stable physical support, withstand the huge reaction force on the anti-wrinkle die during the pipe bending process, and change the angle of the inclined support will change the magnitude and direction of the actual pressure applied to the pipe, ensuring that the front end of the anti-wrinkle die (the part in contact with the pipe) and the rear end of the mandrel are closely matched to form a smooth support surface. Utility Model Content
[0004] In view of this, the present invention provides an anti-wrinkle die inclined support mechanism for a pipe bending machine.
