Embodiment Construction

[0051] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0052] Such as figure 1 As shown, the present invention provides a method for rapid design of progressive dies for body sheet metal parts, comprising the following steps:

[0053] S1. By using the trial-and-error laser tape to test the mold, obtain the final trial punched part;

[0054] S2. Reversely design the punching station according to the final trial punched part.

[0055] Specifically, in step S1, the number of mold trials is at least one. In step S1, one mold trial may be performed, or multiple mold trials may be performed until a qualified trial stamped part is obtained, which is the f...

Abstract

The invention discloses a rapid design method of a progressive die for auto-body sheet metal parts. The method comprises steps as follows: S1, a trial-and-error laser strip is adopted for die trial, and a final test punching piece is obtained; S2, a blanking station is designed reversely according to the final test punching piece. According to the design method for the blanking station of the progressive die for the auto-body sheet metal parts, the die repair time of the blanking station in the progressive die can be reduced greatly, so that die debug time is reduced, and auto-body developmentcycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of metal stamping, in particular, the invention relates to a rapid design method for a progressive die of a body sheet metal part. Background technique [0002] Body sheet metal parts usually have complex shapes and strict shape and position accuracy, so there are many station settings for progressive dies of body sheet metal parts. Depending on the complexity of the body sheet metal parts, the punching (punching, trimming) process is generally set in the first three to six stations in the design of the progressive die station, the purpose of which is to provide a certain shape of forming material for the subsequent forming station piece. The stamping accuracy of the trimming station directly affects the stamping accuracy of the subsequent stations, which in turn affects the quality of the product. Therefore, the design of the trimming station has a crucial impact on shortening the workload of mold debuggi...
