Method for repairing stamping die by referring to rebound parameters of workpiece

Abstract

The invention discloses a method for repairing a stamping die by referring to workpiece springback parameters, which comprises the following steps: S1, carrying out stamping production on an initial die to obtain a stamped workpiece; s2, the obtained stamping workpiece is detected on a detection tool, and core data of all parts of the stamping workpiece are detected; s3, the corresponding part of the stamping die is trimmed through the core data obtained through reference; s4, the steps S1 to S3 are circulated until the size of the stamping die meets the tolerance requirement; by the adoption of the method, the standard size and the rebound size of the stamping workpiece are detected through the special laser scanning gauge, after the core data of stamping die repairing are obtained through comparison, accurate die repairing is conducted on the stamping die according to the core data, therefore, the number of times of die repairing of the stamping die is reduced, the stamping workpiece can reach the qualified tolerance more rapidly, and the production efficiency is improved. The die repairing efficiency of the stamping die is effectively improved, the production efficiency and the percent of pass are improved, and the cost is saved.

Description

technical field [0001] The invention relates to a method for adjusting a stamping die, in particular to a method for modifying a stamping die with reference to a workpiece springback parameter. Background technique [0002] The traditional way of repairing stamping dies is determined by the inspection of the stamping workpiece by the inspection tool, and the fixing of the stamping workpiece on the inspection tool relies on a special quick clamping and inspection tool clamping mechanism. During the inspection process. The important parameters of the qualified stamping workpiece are accurately calculated, and finally the stamping die is repaired according to the parameters measured by the inspection tool; however, there are still some defects in this method, and the method does not consider the stamping workpiece itself. The springback parameters of the standard stamping workpiece are used to repair the stamping die, and the stamping workpiece is obtained by stamping after the...

Problems solved by technology

[0002] The traditional mold repairing methods of stamping dies are all determined by checking the stamping workpiece with the inspection tool, and fixing the stamping workpiece on the inspection tool depends on the special quick clamp and inspection tool clamping mechanism. The important parameters of the qualified stamping workpiece are accurately calculated, and finally the stamping die is repaired according to the parameters measured by the inspection tool; however, there are still some defects in this method, which does not take into account the stamping workpiece itself The springback parameters of the standard stamping workpiece are used to repair the stamping die, and after the mold is repaired, the stamping workpiece is stamped or there is still a large deviation in the stamping workpiece due to springback factors. If the springback is serious, it will directly Affect the qualification rate of the overall production, directly affect the cost of production materials and processing procedures, and generate unnecessary waste
