The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0020] The first embodiment of the present application is as follows:

[0021] Please refer to Figures 1 to 3 , in which Figure 1 is a schematic structural diagram of the first embodiment of the present invention, Figure 2 is a perspective view of the first embodiment of the present invention, Figure 3 is a top view of the first embodiment of the present invention.

[0022] The utility model provides a magnet steel groove mold, which comprises a bottom plate 101 and a stamping mechanism. The stamping mechanism includes a lower template 102, an upper template 105, four vertical rods 106, a mounting frame 107, a bidirectional threaded rod 108, a motor 109, a convex block 110, multiple groups of support components, two groups of clamping components and multiple groups of reset components. Each group of the clamping components includes a telescopic rod 111, a clamping plate 112, an anti-slip pad 113 and a moving member. The moving member includes a moving block 114 and a connecting plate 115. Each group of the reset components includes a hydraulic rod 116 and a spring 117. Each group of the support components includes a support rod 118 and a cushion block 119. The foregoing solution solves the problem in the prior art that the rotor sheet is not fixed, and the rotor sheet is prone to displacement during stamping, resulting in the scrapping of the rotor sheet.

[0023] For this specific embodiment, one end of each of the four vertical rods 106 is fixedly connected to the bottom plate 101, and the other end of each of the four vertical rods 106 is fixedly connected to the lower template 102. Multiple groups of the reset components are all arranged on the upper surface of the lower template 102. The upper template 105 is fixedly connected to multiple groups of the reset components respectively. The convex block 110 is fixedly connected to the upper template 105 and is located on the lower surface of the upper template 105. The lower template 102 has a groove 103 adapted to the convex block 110. The mounting frame 107 is fixedly connected to the upper surface of the bottom plate 101. Two groups of the clamping components are symmetrically arranged on one side of the mounting frame 107. The bidirectional threaded rod 108 is in threaded cooperation with two groups of the clamping components respectively. Two ends of the bidirectional threaded rod 108 are rotatably connected to the mounting frame 107 respectively. The motor 109 is fixedly connected to one end of the mounting frame 107. The output end of the motor 109 is fixedly connected to one end of the bidirectional threaded rod 108. Multiple groups of the support components are all arranged on the lower surface of the bottom plate 101. When specifically in use, the upper template 105 is connected to a pressure device, and then the rotor sheet is placed on the lower template 102. The motor 109 is started. The output end of the motor 109 drives the bidirectional threaded rod 108 to rotate, so that two groups of the clamping components move relatively, thereby clamping and fixing the rotor sheet. Then, the upper template 105 is pressed down by the pressure device. The upper template 105 drives the convex block 110 to move downward until the convex block 110 penetrates through the groove 103, thereby completing the stamping of the magnet steel groove of the rotor sheet.

[0024] Among them, the moving member is arranged below the lower template 102. The lower template 102 has a sliding groove 104. The clamping plate 112 is arranged in the sliding groove 104. One end of the telescopic rod 111 is fixedly connected to the moving member, and the other end of the telescopic rod 111 is fixedly connected to the clamping plate 112. The anti-slip pad 113 is fixedly connected to the clamping plate 112 and is located on one side of the clamping plate 112. When specifically in use, the telescopic rod 111 drives the clamping plate 112 to move up and down, thereby adjusting the height of the clamping plate 112 so that the upper end of the clamping plate 112 is on the same horizontal plane as the upper surface of the rotor sheet, avoiding the clamping plate 112 blocking the upper template 105 during stamping. By rotating the bidirectional threaded rod 108, the moving member moves, and the moving member drives the clamping plate 112 to move through the telescopic rod 111, thereby clamping and fixing the rotor sheet.

[0025] Secondly, one end of the moving block 114 is in threaded cooperation with the bidirectional threaded rod 108. The other end of the moving block 114 penetrates through the installation frame 107 and is slidably connected to the installation frame 107. One end of the connecting plate 115 is fixedly connected to the moving block 114, and the other end of the connecting plate 115 is fixedly connected to the telescopic rod 111. When specifically in use, the bidirectional threaded rod 108 rotates, causing the moving block 114 to move, and the moving block 114 drives the connecting plate 115 to move.

[0026] At the same time, one end of the hydraulic rod 116 is fixedly connected to the lower template 102, and the other end of the hydraulic rod 116 is fixedly connected to the upper template 105. The spring 117 is sleeved outside the hydraulic rod 116. One end of the spring 117 is fixedly connected to the lower template 102, and the other end of the spring 117 is fixedly connected to the upper template 105. When specifically in use, when the pressure device drives the upper template 105 to move downward, the hydraulic rod 116 will be stressed and contract, and at the same time the spring 117 contracts. After stamping is completed, under the elastic potential energy of the spring 117, the hydraulic cylinder is stretched, so that the upper template 105 is reset.

[0027] In addition, one end of the support rod 118 is fixedly connected to the bottom plate 101, and the other end of the support rod 118 is fixedly connected to the cushion block 119. When specifically in use, the support rod 118 is used to support the bottom plate 101, and the cushion block 119 can enhance the stability of the support rod 118.

[0028] When using a magnetic steel groove mold of this embodiment, during specific use, connect the upper template 105 to a pressure device, then place the rotor sheet on the lower template 102, drive the clamping plate 112 to move up and down through the telescopic rod 111, so as to adjust the height of the clamping plate 112, making the upper end of the clamping plate 112 be on the same horizontal plane as the upper surface of the rotor sheet, avoiding the clamping plate 112 blocking the upper template 105 during stamping. Start the motor 109, the output end of the motor 109 drives the bidirectional threaded rod 108 to rotate, making the moving block 114 move. The moving block 114 drives the connecting plate 115 to rotate, and the connecting plate 115 drives the clamping plate 112 to move through the telescopic rod 111, thereby clamping and fixing the rotor sheet. Then, press down the upper template 105 through the pressure device, and the upper template 105 drives the convex block 110 to move downward until the convex block 110 penetrates the groove 103, thus completing the stamping of the magnetic steel groove of the rotor sheet. By this method, it can effectively solve the problem in the prior art that the rotor sheet is not fixed, and the rotor sheet is prone to displacement during stamping, resulting in the scrapping of the rotor sheet.
