Three-dimensional laser trimming tool for L-shaped stretch-bending part

Abstract

The invention belongs to the field of tool design, and relates to a tool for three-dimensional laser trimming of an L-shaped stretch-bending part. The tool is composed of an edge cutting die body, an edge pressing device, a jacking device, a supporting device and a laser edge cutting assembly. The trimming die body is of a platform structure, and the edge of the platform structure is matched with the shape of an L-shaped stretch bending piece to be trimmed; the supporting device is used for supporting the trimming die body, and an arc-shaped supporting plate is further arranged on the side face, close to the edge of the trimming die body, of the upper end of the supporting device. The support is used for mounting the jacking device; the edge pressing device, the jacking device and the edge of the platform structure which are mounted on the edge cutting die body jointly define the overall appearance of the L-shaped stretch bending part to be subjected to edge cutting; a certain gap is reserved between the lower end face of the L-shaped stretch-bending piece to be trimmed and the arc-shaped supporting plate, and an upper end flange is pressed and fixed through the edge pressing device. During edge cutting, after the L-shaped stretch bending part to be subjected to edge cutting is positioned, edge cutting is conducted through the laser edge cutting assembly.

Description

technical field [0001] The invention belongs to the field of tooling tool design and relates to a tooling for three-dimensional laser edge trimming of stretch-bending parts. Background technique [0002] At present, the manual trimming of L-shaped stainless steel stretch bending parts (thickness δ≥1mm, length L≥1m) has the problems of high difficulty and low efficiency. L-shaped stainless steel stretch bending parts have high hardness and large springback, and the heavy workload has caused great difficulties for manual trimming and cutting. At the same time, there may be a large gap in the modification effect of the parts depending on the work experience of the workers, which often cannot meet the accuracy requirements of the product. [0003] At the same time, in the process of manual trimming, problems such as skewed part incisions, mismatched joint surface sizes, and large local deformation in the shearing area are prone to occur.
