Self-stacking manufacturing process of punched sheet body

Abstract

The invention, which belongs to the technical field of mechanical manufacturing, discloses a self-stacking manufacturing process of a punched sheet body. The process is implemented as follows: carrying out a material selection process; carrying out a punching process; carrying out a groove type punching process; carrying out a waste back-pressure process; carrying out an appearance punching process; carrying out a sheet body connection process; carrying out sheet body processing; and carrying out a waste removing process. According to the invention, self-buckling is carried out after sheet body punching and thus the sheet body punched out by a punching die is bukcled inside the die automatically, so that the production efficiency is improved, the material losses are reduced, the productioncost is lowered, and the utilization rate of raw materials is increased.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a self-stacking manufacturing process for a punched sheet body used for laminating the punched sheet body. Background technique [0002] The traditional punched sheet body needs to be manually sorted by workers before being stacked. In this way, manual sheet sorting by workers has low production efficiency and high labor intensity. The flakes are generally not superimposed neatly, thus affecting the quality of the product. [0003] In order to overcome the shortcoming that the current technology requires manual sheet trimming by workers, in the Chinese invention patent with the application date of November 17, 2014 and the application number of 201410650021.8, the applicant disclosed a manufacturing process for a straight stator core, including There are the following steps: 1. Stamping and forming; 2. The first step of laser welding inside the punch...

AI Technical Summary

Problems solved by technology

However, the problems in the above method are as follows: 1. It is necessary to add laser welding equipment in the stamping process, and the laser welding equipment is expensive; 2. The stamping speed of the punching machine needs to be highly consistent with the frequency of laser welding in the die, otherwise it is difficult to weld as a whole. The speed can only be 90-120 strokes / minute, which limits the production efficiency; 3. Due to the large vibration of the punching machine and the environment of stamping oil, the laser welding head in the die is prone to failure, which affects the service life of the laser welding equipment; 4. When producing each stator, 2-4 sheets need to be wasted, and the material loss is relatively large
