Description

Technical Field

[0001] The invention relates to the technical field of motor housing processing, and in particular to a stamping device for processing a motor housing of an automobile wiper. Background Art

[0002] The car wiper motor is a motor that drives the car wiper. Its main function is to convert electrical energy into mechanical energy through the rotation of the motor, drive the wiper arm and wiper blade to do reciprocating motion on the windshield surface, so as to remove rain, snow, dust and other debris on the windshield, and ensure that the driver has a good line of sight. The wiper motor is composed of an armature, a magnetic pole, a brush, a commutator, a reduction mechanism, a housing and an output shaft. Among them, the motor housing is an important part of the motor, which mainly plays a role in protecting the internal parts of the motor. For the car wiper motor, the motor housing can prevent dust, moisture, oil and other external impurities from entering the motor, and avoid these impurities from damaging the precision parts such as the armature, magnetic pole, brush and commutator, thereby ensuring the normal operation of the motor; The existing wiper motor housing is usually processed by stretching and stamping. After the stretching and stamping of the wiper motor housing, the pressure plate needs to be moved up and reset. When the pressure plate is moved up and reset, it is easy to cause the molded housing in friction contact with it to be demolded prematurely, resulting in the molded housing being easily squeezed and deformed when it is demolded prematurely. Therefore, we proposed a stamping equipment for processing automobile wiper motor housings. Summary of the invention

When the annular pressing plate 3 gradually moves downward and approaches the wiper motor housing, the inner side contacts the brush 406 on the outside of the circular pressing block 401 first. The brush 406 on the outside of the circular pressing block 401 rubs and cleans the inner side of the annular pressing plate 3. After the annular pressing plate 3 passes through the brush 406, it will immediately contact the annular concave piece 407 on the outside of the circular pressing block 401. The inner side of the annular pressing plate 3 is covered by arranging an annular concave piece 407 on the outside of the circular pressing block 401 and below the brush 406. By arranging a bottom circular The rod 405 penetrates the upper circular plate 403 to slide and limit the elastically connected circular pressure block 401. After the stamping is completed, the annular pressure plate 3 moves back upward. At this time, the pushing spring 402 continues to push the circular pressure block 401 to push and press the formed motor housing through the extension force until the annular pressure plate 3 moves up to a distance from one end of the ejection device 5. The pushing spring 402 is in a fully extended state. At this time, the pushing spring 402 drives the bottom circular pressure block 401 to move up to the top of the ejection device 5. After the stretching and stamping of the wiper motor housing is completed, gas is filled into the circular sleeve 501 through the high-pressure air pump 502 and the circular scraper 506 is pushed upward. When the circular scraper 506 moves upward, it drives the long connecting rod 508 and the circular ejection block 509 at the top to move together.When the circular top block 509 moves upward, the molded wiper motor housing mounted on the circular sleeve 501 is unloaded by top punching. At the same time, the circular scraper 506 also pushes the blocking mechanism 507. When the blocking mechanism 507 is compressed by the thrust and moves above the rounded air hole 503, the gas inside the circular sleeve 501 is discharged to the outside between the circular sleeve 501 and the molded wiper motor housing through the rounded air hole 503. The gas discharged through the rounded air hole 503 enters the arc groove 504 and the vertical groove 505. When the circular scraper 506 moves upward to the position of the rounded air hole 503, it will scrape and clean the position of the rounded air hole 503 close to the inner wall of the circular sleeve 501. After the unloading of the formed wiper motor housing is completed, the high-pressure air pump 502 is turned off. At this time, the gas in the circular sleeve 501 is discharged to the outside through the high-pressure air pump 502, and the blocking mechanism 507 will stretch downward and push the circular scraper 506 to move down to a position close to the bottom of the inner wall of the circular sleeve 501. At this time, the blocking mechanism 507 will also block the rounded air hole 503. 03 is blocked. When the air pump is turned off, the extension spring 5074 pushes the first circular plate 5073, the first connecting rod 5072, the square sleeve block 5071, the side circular plate 5078, the limit stopper 5079, the side push spring 50710 and the rounded corner block 50711 to move downward by the extension force. When the rounded corner block 50711 moves downward, it contacts the inner wall of the circular sleeve 501 at the moment of pushing by the side push spring 50710. When the rounded corner block 50711 moves to the position of the rounded corner air hole 503, it is pushed by the side push spring 50710. The thrust of 710 is used to seal the rounded corner air hole 503 tightly. Three limit blocks 5079 are set on one side of the side circular plate 5078 to resist and limit the elastically connected rounded corner block 50711. The rounded corners of the outer surface of the rounded corner block 50711 and the inner wall of the rounded corner air hole 503 are smoothly set to facilitate the rounded corner block 50711 to slide away from the inside of the rounded corner air hole 503 through the rounded corners. The extension spring 5074 and the reset spring 5077 are set in the circular sleeve 501 to push and reset the parts.
