DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, a stamping device for permanent magnet motor stator punching comprises a processing table 1, a fixed disk 2 is fixedly connected to the processing table 1 surface, a plurality of circular array grooves 201 are provided on the outer wall of the fixed disk 2, a rotating disk 3 is rotatably connected to the top of the fixed disk 2, a rotating motor 302 is fixedly connected to the inside of the processing table 1, an output end of the rotating motor 302 passes through the processing table 1 and the fixed disk 2 and is fixedly connected to the rotating disk 3, thereby driving the rotating disk 3 to rotate, and a plurality of circular array feed slots 301 are provided on the outer wall of the rotating disk 3, the number of the feed slots 301 is the same as the number of the grooves 201, and the initial positions are aligned up and down, and two sets of conveyor belts 4 are provided on the processing table 1, and the two sides of the processing table 1 are connected. A support plate 401 is fixedly connected, and a conveyor belt 4 is rotatably connected to the inner wall of the support plate 401. One end of the two groups of conveyor belts 4 is respectively located inside the two groups of grooves 201, and is respectively used to transport the stator punchings to the feed trough 301 aligned with one group of grooves 201, and at the same time take out the stator punchings inside the other group of feed troughs 301. A stamping cylinder 5 is fixedly connected to the top of the processing table 1, and a stamping die 501 is fixedly connected to the output end of the stamping cylinder 5. When the rotating disk 3 rotates to drive the stator punching to move to the lower die 6 fixedly connected to the top of the processing table 1, the lower die 6 is located inside a group of grooves 201, and the stamping cylinder 5 drives the stamping die 501 to move downward to punch the stator punching.

[0025] like Figure 3 and Figure 4As shown, the outer wall of the fixed disk 2 is fixedly connected with multiple groups of arc plates 202, and the multiple groups of arc plates 202 are respectively arranged on the outer side of the rotating disk 3, so that when the rotating disk 3 drives the stator punching inside the feed trough 301 to move on the fixed disk 2, the feed trough 301 is closed by the arc plates 202 during the rotation process, thereby preventing the stator punching from being thrown out of the feed trough 301 due to excessive rotation speed, thereby improving the processing stability and improving the processing efficiency.

[0026] like Figure 2 and Figure 3 As shown, the top belt surfaces of the two groups of conveyor belts 4 mentioned above are flush with the top of the groove 201, so that when the conveyor belt 4 feeds the stator punching sheet into the feed trough 301 aligned with the groove 201, the bottom height of the stator punching sheet is flush with the bottom of the feed trough 301, so that after the rotating disk 3 drives the feed trough 301 to rotate, the inner wall of the feed trough 301 is against the stator punching sheet, which can drive the stator punching sheet at the position of the groove 201 to move on the fixed disk 2 without the problem of resistance.

[0027] like Figure 3 and Figure 5 As shown, a discharge chute 601 is provided on the lower die 6 mentioned above, and the waste material punched out from the lower die 6 is discharged through the discharge chute 601. Then, a discharge chute 101 is provided on the top of the processing table 1, and the discharge chute 101 is connected to the discharge chute 601 to transport the waste material. Then, a receiving hopper 8 is provided inside the processing table 1, and the receiving hopper 8 is located below the discharge chute 101, so as to receive and place the waste material transported by the discharge chute 101.

[0028] like Figure 1 and Figure 3 As shown, the outer walls of the two groups of grooves 201 corresponding to the conveyor belts 4 are fixedly connected with the limiting plates 402. When one group of conveyor belts 4 is used to transport and load the stator punching sheets, the stator punching sheets transported on the conveyor belt 4 are limited by the limiting plates 402, so that the stator punching sheets can accurately enter the interior of the grooves 201 to avoid being blocked.

[0029] like Figure 5As shown, the top of the processing table 1 is fixedly connected to a fixed plate 7, and the side wall of the fixed plate 7 is slidably connected to a slide rod 701. The end of the slide rod 701 is fixedly connected to an arc block 702. The bottom of the arc block 702 is in contact with the top of the lower die 6 and is located inside a group of grooves 201. The outer wall of the slide rod 701 is provided with a spring 703. The two ends of the spring 703 are respectively against the fixed plate 7 and the arc block 702. When the rotating disk 3 drives the stator punching to rotate on the fixed disk 2 to the lower die 6, the tension of the spring 703 pushes the arc block 702 against the side wall of the stator punching, so that the stator punching It is fixed inside the feed trough 301 to avoid displacement of the stator punching sheet when it moves inside the feed trough 301, resulting in stamping deviation, thereby improving the stamping quality of the stator punching sheet. When the rotating disk 3 drives the stator punching sheet inside the feed trough 301 to rotate out from the lower mold 6, the inner wall corners on both sides of the feed trough 301 are against the arc surface of the arc block 702, pushing the arc block 702 to move, and then wait until the lower group of feed troughs 301 moves to the lower mold 6. At this time, the tension of the spring 703 pushes the arc block 702 to again against the stator punching sheet inside the feed trough 301 for positioning.

[0030] The working principle of the present invention is as follows: when the user uses it, the stator punching is conveyed by a group of conveyor belts 4. When the stator punching is conveyed to the top of the groove 201 on the fixed plate 2, the rotating motor 302 is started at this time, and the rotating motor 302 drives the rotating plate 3 to rotate. The inner wall of the feeding groove 301 on the outer wall of the rotating plate 3 is against the side wall of the stator punching, pushing the stator punching in the feeding groove 301 to follow the rotating plate 3 to rotate onto the lower die 6, and then start the stamping cylinder 5. The stamping cylinder 5 drives the stamping die 501 to move downward to stamp the stator punching and then reset. At this time, the rotating motor 302 is started again to drive the rotating plate 3 to rotate, and the feeding groove 301 on the outer wall of the rotating plate 3 pushes the stator punching after stamping to move to another group of conveyor belts 4. At this time, the stator punching is conveyed out from the inside of the feeding groove 301 by the conveyor belt 4, and the material is taken out after the stamping of the stator punching is completed. There is no need for manual loading and unloading, which improves the safety of stator punching and the efficiency of continuous production.

[0031] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
