DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2As shown, the stator and rotor core mold includes a main board 2, a support plate 3 is fixedly installed at the top side edge of the main board 2, a rotating shaft 4 is rotatably installed inside the support plate 3, an eccentric wheel 5 is installed on the outer wall of one end of the rotating shaft 4, the eccentric wheel 5 is located above the middle end of the main board 2, a friction pad 6 is installed on the outer wall of the raised end of the eccentric wheel 5, a driven gear 7 is installed on the outer wall of the other end of the rotating shaft 4, an L-shaped plate 8 is installed on one side of the main board 2, a driving motor 9 is assembled inside the L-shaped plate 8, a driving gear 10 is installed at the output end of the driving motor 9, the driving gear 10 is meshed with the driven gear 7, and a sliding pad 11 is installed on the top side of the main board 2, and the sliding pad 11 is located directly below the eccentric wheel 5;

[0023] Support legs 1 are fixedly installed at the four corners of the main board 2, and a control panel 27 is installed on one side of the main board 2. The control panel 27 is used to control the operation of the electrical components inside the device; when working, in actual application, the feeding rhythm cannot be controlled, which will cause production interruption or stamping dislocation problems in the manufacturing process of the iron core, thereby affecting the quality of the iron core. When the drive motor 9 is started, the driving gear 10 at its output end begins to rotate. Since the driving gear 10 and the driven gear 7 are meshed with each other, the driven gear 7 will rotate with the rotation of the driving gear 10, thereby driving the rotating shaft 4 and the eccentric wheel 5 to rotate. When the raised end of the eccentric wheel 5 contacts the sliding pad 11, due to the presence of the friction pad 6, friction will be generated, pushing the sliding pad 11 and the silicon steel sheet above it to move to the side of the lower mold 12. As the eccentric wheel 5 continues to rotate, the raised end gradually moves away from the sliding pad 11, and the silicon steel sheet stops moving, realizing rhythmic intermittent feeding of the silicon steel sheet, thereby improving the processing quality and efficiency of the iron core.

[0024] See also Figure 1 As shown, a lower mold 12 is installed inside the top side of the main board 2, and a cavity 13 is opened inside the main board 2, and the cavity 13 is connected with the mold hole of the lower mold 12;

[0025] A collecting box 14 is connected to the bottom side of the main board 2, and the collecting box 14 is connected to the cavity 13. A movable door 15 is installed on one side of the collecting box 14 through a hinge, and a fixing buckle 16 is fixed to one side of the movable door 15. During operation, in the stamping production process of the core mold, there will be some unused or redundant materials in the mold after each stamping. If these residual materials are not effectively managed, they will be scattered on the processing table and affect the working environment. During the stamping process, the redundant residual materials will fall off from the mold hole of the lower mold 12 and fall into the cavity 13 inside the main board 2. Then the residual materials will smoothly enter the collecting box 14, which is convenient for subsequent cleaning and processing. When the collecting box 14 needs to be cleaned, the movable door 15 can be opened through the fixing buckle 16 to take out the residual materials to ensure a clean working environment.

[0026] See also Figure 3-4 As shown, two guide rods 17 are symmetrically mounted on the top side of the main board 2, a fixing plate 18 is mounted on the top side of the guide rod 17, a cylinder 19 is mounted on the top side of the guide rod 17, and the action end of the cylinder 19 passes through the fixing plate 18 and is fixedly connected to an action rod 20;

[0027] A moving plate 21 is fixed to the bottom side of the action rod 20, and the four corners of the moving plate 21 are slidably mounted on the outer wall of the guide rod 17 respectively. Two sliding rods 22 are slidably mounted on both ends of the moving plate 21, and a limiting block 23 is fixed to the top of the sliding rod 22. A mounting plate 25 is fixed to the bottom side of the sliding rod 22, and two buffer springs 24 are symmetrically mounted between the mounting plate 25 and the moving plate 21. The buffer springs 24 are respectively sleeved on the outer wall of the sliding rod 22, and an upper mold 26 is installed on the bottom side of the mounting plate 25. When working, the stator and rotor cores are the core components of the motor, which are used to move the motor coils. The magnetic field is concentrated on the motor rotor, which is usually made by stamping silicon steel sheets. Therefore, a stamping die is mainly used. After receiving the control signal, the cylinder 19 will push the movable plate 21 and the upper die 26 below it to move downward through the action rod 20, and perform mold closing and stamping with the lower die 12. During the mold closing process, the buffer spring 24 between the mounting plate 25 and the movable plate 21 will play a buffering role under the cooperation of the damper, reducing the impact force between the upper die 26 and the lower die 12, avoiding damage to the mold or material, and after the stamping is completed, with the push of the silicon steel sheet, the iron core will gradually move away from the main board 2, waiting for the stacking operation.

[0028] Working principle: when the driving motor 9 is started, the driving gear 10 at its output end starts to rotate. Since the driving gear 10 and the driven gear 7 are meshed with each other, the driven gear 7 will rotate with the rotation of the driving gear 10, thereby driving the rotating shaft 4 and the eccentric wheel 5 to rotate. When the raised end of the eccentric wheel 5 contacts the sliding pad 11, due to the existence of the friction pad 6, friction will be generated, pushing the sliding pad 11 and the silicon steel sheet above it to move to the side of the lower mold 12. As the eccentric wheel 5 continues to rotate, the raised end gradually moves away from the sliding pad 11, and the silicon steel sheet stops moving, realizing rhythmic intermittent feeding of the silicon steel sheet, thereby improving the processing quality and efficiency of the iron core;

[0029] After receiving the control signal, the cylinder 19 pushes the moving plate 21 and the upper mold 26 below it downward through the action rod 20 to perform mold closing and stamping with the lower mold 12. During the mold closing process, the buffer spring 24 between the mounting plate 25 and the moving plate 21 will play a buffering role under the cooperation of the damper, reducing the impact force between the upper mold 26 and the lower mold 12, avoiding damage to the mold or material.

[0030] During the stamping process, the excess material will fall off from the die hole of the lower die 12 and fall into the cavity 13 inside the main board 2, and then the excess material will smoothly enter the collection box 14, which is convenient for subsequent cleaning and processing. When the collection box 14 needs to be cleaned, the movable door 15 can be opened through the fixing buckle 16 to take out the excess material, so as to ensure a clean working environment;

[0031] After the stamping is completed, as the silicon steel sheet pushes, the iron core will gradually move away from the main board 2, waiting for the lamination operation.
