[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] The utility model provides a magnetic core stamping mechanism, such as Figure 2-6 As shown, it includes: a slide trough body 1, a slide 2, a circular plate 3 and a positioning column 4. The slide trough body 1 is slidably connected to the slide 2. A circular plate 3 is arranged on the top of the slide 2. A positioning column 4 is coaxially arranged on the top of the circular plate 3. A positioning hole 5 is arranged on the top of the positioning column 4. A stamping cylinder 6 is arranged above the slide trough body 1. Four supporting rods 7 are symmetrically arranged at the bottom end of the stamping cylinder 6. The piston rod of the stamping cylinder 6 is connected downward to the stamping head 8. A bowl-shaped pressing groove is arranged at the bottom end of the stamping head 8.

[0026] The lower end of the punch head 8 is funnel-shaped, and the lower end cross-section is smaller, so that the punch head can better position and punch the magnetic core on the positioning column 4. A base 9 is provided at the lower end of the support rod 7, and a bolt hole 10 is provided on the base 9, which is convenient for the base 9 to be installed on the workbench by bolts. The slide 2 and the circular plate 3 are connected by screws, which is convenient for the installation and disassembly of the slide 2 and the circular plate 3.

[0027] A power box 11 is provided at one end of the chute body 1, a screw 12 is provided inside the chute body 1, the screw 12 passes through the slide 2 and is threadedly connected to the slide 2, one end of the screw 12 is rotatably connected to the inner wall of the chute body 1, the other end of the screw 12 is connected to one end of a rotating shaft 13, the other end of the rotating shaft 13 passes through the side wall of the chute body 1 and extends into the power box 11 and is coaxially connected to the first sprocket 14, and the rotating shaft 13 is rotatably connected to the side wall of the chute body 1. The rotating shaft 13 drives the screw 12 to rotate, and through the threaded transmission of the screw 12 and the slide 2, drives the slide 2 to reciprocate along the chute body 1 to a desired position.

[0028] A motor 15 is disposed on the outer wall of the power box 11, and the output shaft of the motor 15 extends into the power box 11 and is coaxially connected to one end of the second sprocket 16, and the first sprocket 14 is connected to the second sprocket 16 through a chain 17. The motor 15 drives the first sprocket 14, and after the chain 17 is driven and decelerated, the first sprocket 14 is driven to rotate, and the first sprocket 14 then drives the rotating shaft 13 to rotate.

[0029] The working principle and beneficial technical effects of the above technical solution are as follows: the magnetic core to be sealed is placed in the positioning hole 5 at the top of the positioning column 4, the motor 15 is started, and the slide 2 is driven to move along the slide trough body 1. When it moves to the bottom of the punch head 8, the slide 2 stops moving, and the punching cylinder 6 is started to drive the punch head 8 to punch down on the top of the magnetic core, so that the top of the shell 100 collapses inward, thereby completing the packaging of the magnetic core, and the punch head 8 is lifted up. Then, the motor 15 is started to drive the slide 2 to move to the leftmost end of the slide trough body 1, and the packaged magnetic core is taken out. After that, the motor 15 rotates in the opposite direction, so that the slide 2 moves to the right to the initial position. Since the screw is driven to rotate by the motor, and the slide is driven to move by the threaded transmission, the moving position of the magnetic core can be accurately controlled, and the magnetic core is sealed by punching through the cylinder, which improves the positioning accuracy and assembly efficiency of the magnetic core.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
