Die repairing method of stamping die

Abstract

The invention discloses a stamping die repairing method which is carried out according to the following steps that S1, an initial die is subjected to stamping production, and a stamping workpiece is obtained; 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 stamping workpiece is comprehensively detected through the special detection tool, after core data of stamping die repairing are obtained through detection of the detection tool, 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 quickly, 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 repairing a stamping die. 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 special inspection tool relies on the rapid clamping and inspection tool clamping mechanism, which is accurate during the inspection process. The important parameters of the qualified stamping workpiece are 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 parameter is to use the parameters of the standard stamping workpiece to repair the stamping die, and the stamping workpiece obtained by stamping after the mold repairing still has a la...

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, while fixing the stamping workpiece on the special inspection tool depends on the quick clamping and inspection tool clamping mechanism, and the accuracy is accurate 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, which does not take into account the stamping workpiece itself. Springback parameters, use the parameters of the standard stamping workpiece to repair the stamping die, and after the mold is repaired, stamping to obtain the stamping workpiece still has a large deviation due to the springback factor, if the springback is serious, it will directly affect The qualification rate of the overall production, resulting in waste of production materials and processing procedures
