Method for generating feeding inclination of material lifting plate in progressive die, storage medium and CNC machine tool

Abstract

The invention relates to the field of machine tool machining, and particularly relates to a method for generating the feeding inclination of a material lifting plate in a progressive die, a storage medium and a CNC machine tool. The method comprises the steps of reading a 3D graph of the material lifting plate in the progressive die; obtaining all edges on the inner contour of an entity in the 3Dgraph, and finding out the edge facing the set feeding direction as a pre-selected edge; calibrating the pre-selected edge with the material clamping risk as a to-be-processed edge; and performing chamfering treatment on each edge to be machined. By automatically analyzing and identifying the edge with the material clamping risk on the material lifting plate and automatically performing chamferingtreatment, the material clamping risk of the edge is reduced in the machining stage of a material lifting plate machine tool, the subsequent material clamping phenomenon is improved, and the purposesof improving the feeding smoothness of the material lifting plate in the progressive die, shortening the die manufacturing period and improving the machining efficiency are achieved.

Description

technical field [0001] The present invention relates to the field of machine tool processing, and in particular to a method for generating the feeding slope of a lifting plate in a continuous mold, a storage medium and a CNC machine tool, wherein the storage medium contains a computer program, which can be executed by a processor of the CNC machine tool to realize all described method. Background technique [0002] Continuous die refers to the cold stamping die that uses strip-shaped stamping raw materials (abbreviated as material belt) in one stamping stroke, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. Once the stamping is completed, the material belt moves once on the lifting plate at a fixed distance until the product is completed. [0003] For the lifting plate in the existing continuous mold, when the CNC machine tool processes and manufactures the lifting plate according to the 3D structure of the li...

Problems solved by technology

[0003] For the lifting plate in the existing continuous mold, when the CNC machine tool processes and manufactures the lifting plate according to the 3D structure of the lifting plate, the sides of the grooves cut on the lifting plate are all right-angled sides, and the right-angled sides are used in actual production Material jams often occur when the middle material belt is fed. At present, in order to solve this problem, the traditional method is through post-processing, and manual chamfering will occur on the edge of the material jam. As a result, the yield rate declined, everyone could not achieve unity, and the time was not well controlled, resulting in an uncontrollable and lengthy mold manufacturing cycle
