Bidirectional anti-wrinkling plate device

Abstract

The invention discloses a bidirectional anti-wrinkling plate device. The bidirectional anti-wrinkling plate device comprises a base, a rack above the base, a propelling device connected with the rackand an anti-wrinkling device above the propelling device, wherein the propelling device comprises a slide way which penetrates through the rack and is arranged at the upper end of the base and a transverse movement oil cylinder; the anti-wrinkling device comprises an axial propelling oil cylinder arranged above the transverse movement oil cylinder, an anti-wrinkling plate device connected with theaxial propelling oil cylinder and an anti-wrinkling plate lifting inclined plane which is arranged on the rack and is matched with the anti-wrinkling plate device. The bidirectional anti-wrinkling plate device disclosed by the invention has the beneficial effects that the structure is simple and an inner side of an elbow can be effectively prevented from being wrinkled when the elbow is bent leftward and rightward; the propelling device is matched with the anti-wrinkling device so that the anti-wrinkling device can be tightly clung to the inner side of the elbow and a supporting force is provided for the elbow, and furthermore, the quality of the elbow is guaranteed.

Description

technical field [0001] The invention relates to the technical field of numerical control pipe bending machines, in particular to a two-way anti-wrinkle plate device. Background technique [0002] When the CNC pipe bending machine is bending the pipe, the material inside the center line is compressed. When it is bent to a certain angle, due to the large compression force of the material, the material will be pushed back and exceed the tangent point. If the pipe wall in this area If it is not supported by the bending die, when the bending is finished, a large wrinkle will be formed on the pipe. Even if it is flattened with a mandrel and a bending die later, the formed wrinkle cannot be eliminated, resulting in wrinkling inside the elbow and reducing the quality of the elbow. . Contents of the invention [0003] The object of the present invention is to provide a two-way anti-wrinkle plate device. [0004] To achieve the above object, the technical solution proposed by the ...
