[0033] The bottom of two spring 8s is fixedly connected at the top of convex button two 9, and the outside of two reset buttons 11 is engaged with the inside of fixed block 10, so as to provide limit for rotary bending shaft 6, prevent it from rotating too much, the outside of two rotary bending shafts 6 is in contact with the inside of stamping block 4, so as to provide space for the rotation of rotary bending shaft 6, and the bottom of two rotary bending shafts 6 is in contact with the top of stamping seat 13, so as to carry out bending operation.
[0034] With reference to Figures 3 to 4The fixed assembly comprises a motor 14 fixedly connected outside the stamping seat 13 for providing power support for the fixed assembly, and a rotating disc 15 fixedly connected to the driving end of the motor 14, which is in the shape of a circular plate for transmitting the power of the motor 14 to the subsequent structure. The rotating disc 15 is rotatably connected to two rotating bars 16 at the top, and one end of the rotating bar 16 is connected to the rotating disc 15 through a special rotating shaft. This connection allows the rotating bar 16 to move in a circular motion flexibly with the rotating disc 15.

[0037] Secondly, during stamping, by activating the power switch of the hydraulic rod 3, the drive end extends downward, causing the stamping block 4 to move downward. The bottom ends of the two rotating bending shafts 6, which are close to each other, contact the workpiece material and the stamping seat 13, thereby causing the two rotating bending shafts 6 to rotate. The rotation of the rotating bending shafts 6 bends the workpiece, reducing the scratches caused by direct contact and extrusion during stamping. The rotation of the rotating bending shafts 6 causes the convex button 9 to move and stretch the spring 8. After stamping is completed, the reaction force of the spring 8 causes the rotating bending shafts 6 to rotate and reset, thereby locking the reset button 11 inside the fixed block 10 for limiting and facilitating the next use. By using the rotating bending shafts 6 instead of the stamping block 4 to directly extrude and bend the workpiece, the surface scratches that may be caused by direct contact and extrusion are effectively avoided, greatly improving the surface quality of the product, reducing the defect rate, and ensuring the appearance and performance of the product.
