Description

Technical Field

[0001] The utility model relates to the technical field of motor casing processing equipment, in particular to a stamping device for motor casing processing. Background Art

[0002] As the main power source in the national economy, electric motors are widely used in various industries. In industrial production, electric motors provide power for mechanical equipment. They are used as the main power equipment in various fields such as metallurgy, textiles, chemicals, transportation, and construction sites. Modern agricultural machinery and many household appliances are equipped with special electric motors.

[0003] The motor housing is an important part of the motor, and its processing quality directly affects the performance and life of the motor. In the production process of the motor housing, stamping is an important link. After searching, the Chinese patent application number is: CN201510590536.8. A motor housing stamping jig is provided, including a stamping head, a stamping die, a base, a stopper, a detection head, and a driver. The base includes a base and a fixed bracket; the base is fixed with a stamping die, and a fixing groove is provided on the stamping die; the fixed bracket is fixed with a driver, a stopper, and a stamping head connected to the driver; the driver is also connected with the stopper and the detection head, and the driver includes a driving motor (61) and a telescopic shaft connected to the driving motor; the detection head is fixed on the stamping head. The base of the device plays a role in fixing and positioning the explosion-proof motor, and the stamping head is used to position and fix the contact piece. When the preparation is completed, just press down. The characteristics are convenient and simple to improve work efficiency.

[0004] The above technical solution and traditional stamping equipment have the same defect, that is, the lack of fixation of the shell profile.

Moreover, the above technical solution requires manual placement and removal of the motor shell from under the stamping mechanism after the stamping is completed. This method is not only inefficient, but also has certain safety hazards. Therefore, we need to propose a stamping device for motor shell processing. Utility Model Content
