A kind of sheet metal intelligent bending machine

Abstract

The invention provides an intelligent plate bending and edge buckling machine. The intelligent plate bending and edge buckling machine comprises a working table, a bending die, a working frame, a corrugated bending device and an edge buckling device. According to the intelligent plate bending and edge buckling machine, the problems that when an existing bending machine is used for producing roundsteel sheets with different diameters in a bending manner in the process of bending semicircular steel sheets, the bending heads and the bending lower dies need to be frequently replaced, and the production efficiency is influenced are solved; the problems that in the process of stamping the corrugated convex body structure, raised corrugations is caused to generate springback, springback occurs due to the action of stress in once stamping, and the product quality is influenced are solved; and the problems that when the existing bending machine bends the corners of the plates, prismatic creases at the corners are caused, and the later stitching is affected, so that the splicing of two semi-circular corrugated pipes cannot be attached, the curved surface after the later joint is not smooth,the corrugated creases are prone to cause the corrugated pipe to be buried in soil for a long time to be extruded and broken along the crease direction of the corrugated pipe due to the pressure of the soil, and use is affected are solved.

Description

technical field [0001] The invention relates to the technical field of plate bending, in particular to an intelligent plate bending machine. Background technique [0002] Metal corrugated culverts, also called corrugated pipe culverts, refer to threaded corrugated pipes for culverts buried under roads and railways. It is used in culverts in highways, railways, small bridges, passages, retaining walls, and retaining walls of various mine roadways. [0003] The existing semicircular corrugated steel sheet mainly uses a bending machine to cooperate with stamping to complete the internal corrugated convex body, but the existing bending machine mainly has the following problems in the process of bending the semicircular steel sheet: [0004] 1. Bending and producing round steel sheets with different diameters requires frequent replacement of the bending head and the lower bending die, which affects production efficiency, and the raised corrugated convex structure will cause rais...

AI Technical Summary

Problems solved by technology

[0007] The present invention can solve the problem that in the process of bending semi-circular steel sheets in existing bending machines, the production of circular steel sheets with different diameters requires frequent replacement of the bending head and the lower bending mold, which affects production efficiency, and In the process of stamping the corrugated convex body structure, the raised corrugated structure will cause rebound, and a stamping will rebound due to the stress, which will affect the product quality; and when the existing bending machine bends the corner of the plate There are prismatic creases at the corners, which affect the later splicing, and cause two semicircular corrugated pipes to be spliced ​​together. The pressure of the soil causes the corrugated pipe to be squeezed along the direction of the crease and break, which affects the use and other problems
