Description

Technical Field

[0001] The utility model relates to the technical field of silicon steel sheet processing, in particular to a stamping device for stator silicon steel sheets with automatic material discharging. Background Art

[0002] The stator and rotor of a motor are formed by stacking a certain number of punching sheets. Therefore, multiple groups of silicon steel sheets are used. During the processing of silicon steel sheets, it is necessary to punch the silicon steel strip into silicon steel sheets with the required shape through stamping operations.

[0003] During the process of stamping silicon steel sheets, the up-and-down movement of the moving die is used to cooperate with the fixed die at the bottom to complete a stamping of the silicon steel plate or silicon steel strip once. Then, it is necessary for the processing personnel to remove the formed silicon steel sheet from the processing table, and after adjusting the position of the silicon steel plate or silicon steel strip, perform stamping again.

[0004] During the above-mentioned processing of silicon steel sheets, since it is necessary for the processing personnel to manually adjust the position of the silicon steel plate or silicon steel strip after each stamping and collect the formed silicon steel sheets, the efficiency of stamping processing is relatively low. For this reason, we propose a stamping device for stator silicon steel sheets with automatic material discharging. Summary of the Utility Model

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-2 , a stator silicon steel sheet stamping device with automatic material discharging, including a bench 20, a moving mold 30 and a material discharging assembly 40. The silicon steel strip 10 to be stamped can be placed on the tabletop of the bench 20; the moving mold 30 is installed on the top of the bench 20 and can be driven by a hydraulic system to move downward to stamp the silicon steel strip 10. The material discharging assembly 40 can change its position following the movement of the moving mold 30, and it can push the stamped silicon steel strip 10 to move on the bench 20.

[0023] Refer to Figure 2, the bench 20 may include a bottom table 21, a top table 22, a fixed mold 23, a silicon steel sheet leakage trough 24, an inner support plate 25, and two groups of limit side guards 26. The top of the bottom table 21 can be used as a processing tabletop for placing the silicon steel strip 10, and limit side guards 26 extending along the length direction of the bottom table 21 are formed on both opposite sides of the top of the bottom table 21. The silicon steel strip 10 is arranged between the two groups of limit side guards 26, so that the two groups of limit side guards 26 can prevent the silicon steel strip 10 from shifting left and right. The fixed mold 23 is embedded and fixed on the top of the bottom table 21, and the fixed mold 23 is arranged directly below it in cooperation with the moving mold 30. During stamping, the required-shaped silicon steel sheet can be punched out by the cooperation of the fixed mold 23 and the moving mold 30. The lower end of the top table 22 is fixedly connected to the outer wall of the bottom table 21, and the top of the top table 22 supports and installs the moving mold 30 and the required hydraulic system. The silicon steel sheet leakage trough 24 is formed on the top of the bottom table 21, and the silicon steel sheet leakage trough 24 penetrates through the top tabletop of the bottom table 21. The shape of the silicon steel sheet leakage trough 24 is matched with the stamped silicon steel sheet, so that it can fall through the silicon steel sheet leakage trough 24. An inner support plate 25 is formed in the middle inside the bottom table 21, and a conveyor belt or a collection box is installed above the inner support plate 25. The conveyor belt can convey and remove the silicon steel sheets falling above it; the top of the collection box is open towards the silicon steel sheet leakage trough 24, so that the silicon steel sheets can fall into it for collection.

[0024] Refer to Figure 3, the material discharging assembly 40 includes a following support 41, a support shaft 42, a driving frame 43, a dial groove 44, a stress column 45, a swing frame 46, a support body 47 and a material shifting part 48. One side of the following support 41 facing the moving die 30 is connected to the moving die 30, and the other end of the following support 41 is sleeved outside the support shaft 42 and fixedly connected thereto, so that the following support 41 and the support shaft 42 can be driven by the moving die 30 to move up and down. The top end of the driving frame 43 is rotatably connected to the support shaft 42, the dial groove 44 is formed on the driving frame 43, and the stress column 45 passes through the dial groove 44, so that when the support shaft 42 moves, it can drive the driving frame 43 to deflect, and the inner wall of the dial groove 44 applies a force to push the stress column 45. One end of the swing frame 46 close to the stress column 45 is fixedly connected to the stress column 45, and the top of the swing frame 46 is also rotatably connected to the top of the support body 47, so that when the stress column 45 is pushed, it can drive the swing frame 46 to deflect with the connection part with the support body 47 as the rotation center. The lower end of the swing frame 46 is rotatably connected to the middle of the material shifting part 48. When the swing frame 46 deflects, it can push the material shifting part 48 to move. When the material shifting part 48 moves upward above the fixed die 23, it can slide above the silicon steel strip 10; when the material shifting part 48 moves away from the fixed die 23, its bottom can be inserted into the gap between the formed silicon steel sheet and the silicon steel strip 10, and pull the silicon steel strip 10 to move therewith, and at the same time, it can make the silicon steel sheet be pushed and move simultaneously in the punched groove. The bottom of the support body 47 is detachably and fixedly connected to the bench 20.

[0025] In this embodiment, a connection part 471 and a limiting part 472 are formed at the bottom of the support body 47. The connection part 471 is in close contact with the outer wall of the bottom table 21, and the connection part 471 and the bottom table 21 can be connected and fixed by fasteners such as bolts or rivets. The bottom of the limiting part 472 extends above the silicon steel strip 10, and the limiting part 472 can limit the silicon steel strip 10 above it to prevent the silicon steel strip 10 from moving upward, so as to cooperate with the limiting edge 26 to make the silicon steel strip 10 only be able to be pulled by the material shifting part 48 to move in a single direction.

[0026] In this embodiment, a pointed cone-shaped protrusion hook 481 is formed downward at one end of the material shifting part 48 facing the lower part of the moving die 30, so that it can be inserted into the gap between the formed silicon steel sheet and the silicon steel strip 10, thereby pulling the silicon steel strip 10 to move.

[0027] Among all the solutions mentioned above, for the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For all the cases of fixed connection mentioned above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
