Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blanking devices, in particular to a rotor punching sheet continuous blanking device for new energy automobile motors. BACKGROUND

[0002] Under the background of rapid development of the new energy automobile industry, the machining precision and production efficiency of the rotor punching sheet of the motor, as a core power component, directly affect the vehicle performance and manufacturing cost. At present, the continuous blanking device for the rotor punching sheet of the new energy automobile motor still has significant technical bottlenecks in the waste treatment and workpiece positioning links.

[0003] Traditional blanking equipment relies on the blowing method to discharge waste. Although this method has a simple structure, it has many drawbacks. On the one hand, the waste is easy to accumulate and jam in the narrow gap or bend of the blanking equipment under the action of the airflow, which not only hinders the normal operation of the equipment, but also may cause mechanical part wear due to forced dredging, thereby shortening the service life of the equipment. On the other hand, the high-speed airflow is easy to cause the waste to collide violently with the inner wall of the conveying pipe, resulting in the adhesion of waste debris to the pipe wall. Long-term accumulation forms stubborn dirt, and the cleaning process needs to be frequently stopped, which seriously reduces the production continuity and equipment operation efficiency.

[0004] In addition, the accurate positioning of the rotor punching sheet during the blanking process is also a key factor restricting product quality. Traditional mechanical fixing devices mostly use rigid clamping structures, which are difficult to realize the positioning of the punching sheet. This not only increases the rate of defective products, but also requires additional labor and equipment for subsequent correction, further increasing the manufacturing cost. SUMMARY

[0041] The mounting shell 51 is used as the main installation base for the installation of other components, the piezoelectric ceramic 52, the electrode 53, the front driver 54 and the rear driver 55 are connected by the pre-tightening bolt 56, so that the electrode 53 applies voltage to the piezoelectric ceramic 52 after being electrified, then the piezoelectric ceramic 52 vibrates, the vibration of the piezoelectric ceramic 52 is converted into sound waves by the front driver 54 and the rear driver 55, the vibration of the piezoelectric ceramic 52 arranged in order forms a high-intensity standing wave sound field through the front driver 54 and the rear driver 55, which has a certain effect on the waste, and then the suspended waste is taken away by the conveying pipe 3 and the magnetic field generating device 6.
