Stamping die applied to motor shell production and machining method

Abstract

The invention discloses a stamping die applied to motor shell production and a machining method, and relates to the technical field of motor shell machining, the stamping die comprises an upper die and a lower die which are arranged up and down, a stamping area is formed between the upper die and the lower die, and a feeding port and a discharging port are formed in the stamping area; a first stamping head and a second stamping head are sequentially arranged on the upper die in the direction from the feeding port to the discharging port, the first stamping head is used for stamping a long-strip-shaped opening in a material, the second stamping head is used for stamping a step at the position close to the opening, a blanking groove is formed in the lower die, and the blanking groove is communicated with the discharging port. The blanking groove and the first punching head are oppositely arranged, the defects existing in the background technology are effectively overcome, the machining difficulty is greatly reduced, the cost is low, and the cost performance is high.

Description

technical field [0001] The invention relates to the technical field of motor shell processing, in particular to a stamping die and a processing method applied in the production of motor shells. Background technique [0002] In the production of motor shells, some shells will have steps inside the shell in order to match the installation of the end cover, that is, a section of arc-shaped groove is opened on the inner wall of the shell. The traditional processing method is to roll the plate for making the shell into cylindrical shape, and then through special slotting equipment, the arc-shaped slot body is opened on the inner wall of the shell, that is, the steps mentioned above. [0003] However, there are many defects in this processing method: first, because the groove is made on the inner wall of the shell, it requires high precision of the groove equipment, and the equipment with high precision is expensive, difficult to operate, and has a long service life. It is relati...

AI Technical Summary

Problems solved by technology

[0003] However, there are many defects in this processing method: first, because the groove is made on the inner wall of the shell, it requires high precision of the groove equipment, and the equipment with high precision is expensive, difficult to operate, and has a long service life. It is relatively short and requires constant adjustment of equipment parameters to ensure the accuracy of slotting; 2. The use of equipment requires high professional knowledge of technicians. If novice technicians operate, there will often be defective products, and there is a certain technical threshold, which is not conducive to mass promotion and use. ; 3. Such equipment is usually complex in structure, difficult to maintain and maintain, and the cost of enterprise use is high
