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

Embodiment 1

[0023] Example 1: as figure 1 A self-stacking manufacturing process of a blanking sheet body is shown, and the manufacturing process includes the following steps: firstly, a material selection process is performed, and raw materials are selected according to the processing requirements of the workpiece; The sheet body of the workpiece needs to be processed; then punch the groove shape, and transport the sheet body to the stamping die I. According to the requirements of the groove shape in the sheet body, punch the groove shape in the sheet body, and the groove shape can be circular Shape or oval or square; it can also be irregular shape, and part of the waste punched out of the groove is discharged, part of it is left in the die, and part of the waste left in the die is spaced apart from each other; The waste in the die is back pressed into the groove with stamping parts, so that the waste is connected with the sheet body; that is, the waste is punched back into the groove of ...

Embodiment 2

[0025] Example 2: A self-stacking manufacturing process of a blanked sheet body. The other processes are the same as those of Example 1, but during the connection process of the sheet body, the waste is punched back into the groove shape of the sheet body, and the surface of the waste is The surface of the sheet body is the same plane, and then the connecting piece is punched in the waste, and the two adjacent pieces of waste are connected to each other by the connecting piece. For example, when the first sheet body and the second sheet body are superimposed, the connecting piece makes the The waste material of the first sheet is fixedly connected with the waste material of the second sheet, so that the sheet body of the first sheet and the sheet body of the second sheet are connected together. As a further improvement measure of the present invention, in the scrap, the concave part and the convex part are punched, and the concave part and the convex part of the two adjacent sc...

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...
