Description

Technical Field

[0001] The utility model relates to the technical field of claw pole processing, and more specifically, to a heading device for claw poles of automotive generators. Background Technique

[0002] During the forging process of claw poles, the raw materials need to be formed through heating, upsetting, rough forging, finish forging, trimming, annealing, and cold finishing. Among them, the steps of upsetting, rough forging, and finish forging are collectively referred to as the hot forging treatment of claw poles.

[0003] After retrieval, it is found that the publication number is CN208083318U, and the name is an efficient claw pole hot forging device. This application proposes that during the processing of claw poles, the cylindrical processing raw materials are directly placed in a processing mold after heating, and then the processing raw materials are extruded to directly form the hot-forged claw poles in the processing mold at one time to reduce the steps of claw pole hot forging; due to the relatively complex structure of this kind of claw pole and high precision requirements for each part, while the precision of the claw pole formed by this one-time hot forging is low, after forming, the claw pole needs to be polished by workers using sandpaper, etc. to improve the precision of each part of the claw pole, which greatly reduces the production efficiency of the claw pole. By setting an upsetting table, a rough forging mold, and a finish forging mold to hot forge the cylindrical processing raw materials step by step into the required finish-forged claw poles, it is beneficial to improve the precision of the claw pole during the hot forging process, and thus there is no need for workers to polish the precision of the claw pole anymore, which is beneficial to improving the production efficiency. However, this application still requires staff to manually move the claw pole, which is rather troublesome. At the same time, when moving the claw pole, the clamping tool needs to reach under the pressing head. When a mechanical failure or human negligence occurs, the sudden operation of the pressing head is extremely likely to cause danger, and further improvements can be made.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

Subsequently, the servo rotating table 1 drives the rough upsetting die 4 to rotate to directly below the electromagnet 10. The electric cylinder 7 extends and the electromagnet 10 moves downward to place the raw material into the rough upsetting die 4. Then, the electromagnet 10 is powered off and the electric cylinder 7 shortens. Subsequently, the servo rotating table 1 drives the rough upsetting die 4 to rotate to directly below the press-fitting head 11. The press-fitting head 11 moves downward again to perform rough upsetting forming on the raw material. Then, the press-fitting head 11 moves upward. The servo rotating table 1 drives the rough upsetting die 4 to rotate to directly below the electromagnet 10. The electromagnet 10 picks up the claw pole after rough upsetting forming. The servo rotating table 1 drives the fine upsetting die 5 to rotate to directly below the claw pole. The electric cylinder 7 extends to place the roughly upset claw pole into the fine upsetting die 5. Subsequently, the servo rotating table 1 drives the fine upsetting die 5 to rotate to directly below the press-fitting head 11. The press-fitting head 11 moves downward to perform fine upsetting forming. This device uses the servo rotating table 1, the electric cylinder 7, and the electromagnet 10 to complete automatic transposition upsetting, eliminating the trouble of manual transfer, improving the convenience of use and work efficiency. At the same time, after fine upsetting forming, the press-fitting head 11 rises. The servo rotating table 1 drives the fine upsetting die 5 to rotate to directly below the electromagnet 10. The electromagnet 10 moves downward to suck the fine upsetting formed claw pole. Then, the electric cylinder 7 shortens to take out the formed claw pole from the fine upsetting die 5. Subsequently, the servo rotating table 1 drives the unloading table 3 to move to directly below the claw pole. The electromagnet 10 moves downward to place the claw pole on the top surface of the unloading table 3. Then, the electromagnet 10 is powered off and moves upward.
