Trimming mold manufacturing method, computer readable storage medium and CNC trimming mold manufacturing machine tool

Abstract

The invention relates to a trimming die manufacturing method, a computer readable storage medium and a CNC trimming die manufacturing machine tool. The method comprises the following steps: reading aproduct model of a 3D image; acquiring a vertical punching direction determined by an engineer on a product model, and a closed trimming line drawn on the horizontal plane of the product model; by taking the horizontal plane of the top layer on the product model as a starting point, moving the closed trimming line in the reverse direction of the stamping direction, so that a punching head is formed, wherein the contour of any horizontal section of the punching head is the same as the contour of the closed trimming line for forming the punching head; forming a lower module capable of covering the product model, controlling the middle of the top surface of the lower module to be recessed inwards, and digging a groove with the groove opening contour as same as the contour of the closed trimming line in the top surface of the lower module, wherein the recessed surface formed by recessing is the same as the bottom molded surface of the product model, and the position of the groove in the recessed surface is the same as the projection position of the closed trimming line on the bottom molded surface; and converting the punching head and an insert into CNC codes for machining of the CNC machine tool.

Description

technical field [0001] The present invention relates to the field of stamping and trimming, and in particular to a method for manufacturing a trimming die, a computer-readable storage medium and a CNC trimming die manufacturing machine using the medium. There is a computer program stored in the medium, and the computer program can be trimmed by a CNC. A processor of the mold manufacturing machine executes and realizes the trimming mold manufacturing method. Background technique [0002] In the hardware manufacturing industry, the die and the punch are used to press against each other to form the blank. Most of the blank after stamping is the required stamping product, but there is a small part of the excess, such as the blank on the blank. The part outside the edge of the die / punch and the part inside the edge that needs to be dug must be punched and cut in the subsequent process to achieve trimming. The above trimming process is carried out using a punch die and a strippin...
