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] Embodiment 1: as figure 1 Shown is a self-stacking manufacturing process for punching sheets. The manufacturing process includes the following steps: firstly, the material selection process is carried out, and the raw material is selected according to the processing requirements of the workpiece; The sheet-shaped body of the workpiece needs to be processed; then the groove shape is stamped, and the sheet-shaped body is transported to the stamping die Ⅰ. According to the requirements of the groove shape in the sheet-shaped body, the groove shape is punched in the sheet-shaped body. The groove shape can be round. Shape or ellipse 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 arranged at intervals; then, part of the waste left in the die The waste in the die is back-pressed into the groove with a stamping part to connect the waste with the she...

Embodiment 2

[0025] Embodiment 2: A self-stacking manufacturing process of punching sheets, the other processes are the same as in Example 1, but in the process of connecting the sheets, the waste is flushed back into the groove of the sheet, and the surface of the waste is in contact with the groove of the sheet. The surface of the sheet is the same plane, and then the connecting piece is punched in the scrap, and the two adjacent pieces of waste are connected to each other by using the connecting piece, for example, when the first sheet is superimposed on the second sheet, the connecting piece makes The waste material of the first piece is fixedly connected with the waste material of the second piece, so that the first piece of sheet is connected with the second piece of sheet. As a further improvement measure of the present invention, in the waste material, the concave part and the convex part are punched, and the concave part and the convex part of the two adjacent pieces of waste mater...

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 lamination of punched sheet objects. Background technique [0002] Before laminating the traditional blanked sheets, workers are required to manually arrange the sheets. In this way, the production efficiency is low and the labor intensity is high after the workers manually arrange the sheets. For flakes, the stacking is generally not very neat, thus affecting the quality of the product. [0003] In order to overcome the shortcomings of the current technology that requires workers to sort the sheets manually, in the Chinese invention patent with the application date of November 17, 2014 and the application number 201410650021.8, the applicant disclosed a manufacturing process for a straight stator core, including There are the following steps: 1. Stamping forming; 2. The first step of laser welding in the die...
