Scaling method of drawing procedure processing data

Abstract

The invention relates to a scaling method of drawing procedure processing data. The scaling method is characterized by including following steps: first, before a mold processing data molded surface and an outline of drawing procedure is scaled, the structural style of the mold is learned about and whether a single-groove mold, a double-groove mold, and a mold in pairs at the left and the right and in common mode at the front and the back or not; a mold designer refers to a corresponding scheme instruction book, learns about design information and a fine mold face design scheme and confirms a scaling center coordinate system; in the design process of the punching technology, datum points are set in consideration of pressure centers of workpieces; and according to the fine mold face design scheme, design of the molded surface of the mold of the drawing procedure and the outline is finished, and then the molded surface and the outline are scaled up 1.0003-1.0007 times along the integral plane (X,Y) direction. In consideration of shrinking of a product after drawing, the molded surface and the outline are scaled up to compensate, requirements of size precision of the product can be rapidly achieved, the situation that a drawing piece is placed on a latter trimming mold to be smooth and matched is guaranteed, time of mold grinding by a fitter is reduced, labor intensity is reduced, the production cycle of the mold is shortened, and manufacturing cost of the mold is reduced.

Description

technical field [0001] The invention relates to a method for scaling processing data in a drawing process, which is used for drawing and forming molds of all products. Background technique [0002] In the past, the processing data profile and profile of the drawing process were designed according to the 1:1 theoretical digital model. After the product is drawn, the profile will shrink and change, which will affect the dimensional accuracy of the product, especially for the side wall closed parts. The drawn parts are placed on the It is difficult to install the trimming mold in the subsequent sequence. The fitter needs to do a lot of manual training on the side wall of the trimming punch to ensure that the parts fit and match the mold. The labor intensity of the fitter is enhanced, the manufacturing cost is increased, and the manufacturing cycle of the mold is prolonged. Contents of the invention [0003] The purpose of the present invention is to provide a method for redu...
