The punch 3 is vertically mounted on an upper die base 2 and is located above the bottom die 1. The upper end of the punch 3 is equipped with a stamping power source and a return spring. The stamping power source is preferably hydraulically driven. The bottom die 1 is provided with an arc-shaped groove 4 that matches the bearing bush. The bottom of the arc-shaped groove 4 is provided with a punch 5. A stripper block 6 is elastically movable inside the arc-shaped groove 4. Specifically, the lower end of the stripper block 6 is an arc surface that matches the arc-shaped groove 4. A return spring is provided at the rear end of the stripper block 6. To achieve elastic movement, pressure blocks 7 are provided on both sides of the arc groove 4. The middle of the pressure block 7 is hinged to the bottom mold 1. An upper swing force source 17 is provided at the outer end of the pressure block 7. The upper swing force source 17 is preferably a cylinder. The cylinder is located below the outer end of the pressure block 7 and drives the outer end of the pressure block 7 to swing upward through the cylinder shaft. The inner end of the pressure block 7 is pressed tightly with the bearing in the arc groove 4. A limiting block 8 is provided at the lower end of the upper mold base 2. The limiting block 8 forms the upper limit of the inner end of the pressure block 7. A compression spring is also provided between the pressure block 7 and the bottom mold 1.

[0015] As a further improved specific implementation, the two lower corners of the limiting block 8 are both set as first inclined surfaces 9, and the upper corner of the inner end of the pressing block 7 is set as a second inclined surface 10, with the first inclined surface 9 and the second inclined surface 10 providing a limiting fit.

[0016] As a further improved specific implementation, the inlet side of the arc-shaped groove 4 is provided with a conveying seat 11 that can move back and forth. The front end of the conveying seat 11 is provided with a double support rod 12 that can be elastically extended and retracted. The bearing surface of the double support rod 12 is flush with the bearing surface of the arc-shaped groove 4 so that the bearing bush can be smoothly transferred between the two. When the front end of the double support rod 12 touches the bottom mold 1 and retracts, the conveying seat 11 pushes the bearing bush on the double support rod 12 into the arc-shaped groove 4.

[0017] As a further improved specific implementation, the double support rod 12 is slidably mounted on the conveyor seat 11, the rear end of the double support rod 12 is fixed on the connecting plate 13, the connecting plate 13 is connected to one end of the guide rod group 14, the other end of the guide rod group 14 is mounted on the rear end of the conveyor seat 11, and the guide rod group 14 is provided with a return spring 15, and the extension and retraction of the corresponding double support rod 12 is achieved by the guidance of the guide rod group 14 and the return spring.

[0018] As a further improved specific implementation, the front end of the conveyor seat 11 is made of magnet material to attract the bearing bush, assist the bearing bush in positioning on the double support rod 12, and attract the bearing bush to move in and out of the arc groove 4.

[0019] As a further improved specific implementation, a material handling robot 16 that can move horizontally and vertically is provided above the conveyor seat 11. The horizontal and vertical movements are achieved through a cross slide rail and a drive. The material handling robot 16 cooperates with the bearing gripper, and the corresponding material handling robot is a pneumatic gripper.

[0020] The working principle of this utility model is as follows: the material handling robot 16 grasps the bearing and places it on the double support rod 12 at the front end of the conveyor seat 11. The magnet at the front end of the conveyor seat 11 attracts the bearing for initial positioning. The conveyor seat 11 moves forward, and the front end of the double support rod 12 retracts after touching the bottom mold 1, smoothly pushing the bearing into the arc-shaped groove 4 of the bottom mold 1. The bearing also pushes the stripping block 6 backward to make way. Then, the upper swing force source 17 drives the outer end of the pressure block 7 to swing upward, causing the pressure block 7 to rotate around the hinge point. The inner end of the pressure block 7 presses down to tighten the bearing. Then, the punching die 3 moves downward to complete the punching operation on the bearing bush. After punching, the punching die 3 moves upward, the upper swing force source 17 resets, the compression spring drives the pressure block 7 to reset, the upper swing limit of the inner end of the pressure block 7 is located at the limit block 8, and the stripping block 6 in the arc groove 4 pushes the bearing bush forward under the elastic action. The bearing bush is attracted to the magnet at the front end of the conveyor seat 11. As the conveyor seat 11 resets, the double support rod 12 extends to support the bearing bush. Finally, the material handling robot moves to grab the punched bearing bush and transfer it to the next process.

[0021] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
