[0024] The bottom end of bolt 3 is screw-connected on the top inside of connecting plate 2, the left and right sides of guide plate 1 are fixedly connected with link block 4, the inside of link block 4 is slidably connected with fixed rod 5, the inside of fixed rod 5 is slidably connected with sliding rod 6 for transmitting force, the top of sliding rod 6 is fixedly connected with pull disc 7 for facilitating the pulling of staff, the bottom end of sliding rod 6 is fixedly connected with arc block 8 with arc shape, for facilitating subsequent movement, the outside of arc block 8 is slidably connected on the bottom end inside of fixed rod 5 for providing stable movement, the bottom end of arc block 8 is fixedly connected with limiting rod 9 for transmitting force, the outside of limiting rod 9 is slidably connected on the bottom end inner wall of fixed rod 5 for providing stable movement, the outside of limiting rod 9 is sleeved with strong spring 10 for providing spring force and rebound force;

[0025] The bottom end of the limiting rod 9 is fixedly connected with a limiting plate 11 for limiting the position of the limiting rod 9. The bottom end of the fixed rod 5 is provided with a containing hole 12 to provide additional containing space. The limiting plate 11 is slidably connected to the inside of the containing hole 12. One end of the strong spring 10 is fixedly connected to the top end of the containing hole 12, and the other end of the strong spring 10 is fixedly connected to the top end of the limiting plate 11. The middle end of the fixed rod 5 is provided with two movable holes 13 on the outside. The movable holes 13 are movably connected with the engaging balls 14 inside for rolling. In the event of an accident, the engaging balls 14 are rolled in place instead of being directly detached. The outside of the sliding rod 6 is in contact with the outside of the engaging balls 14 for extruding the engaging balls 14 during the clamping process to ensure the stability of the engaging balls 14.

[0026] Referring to Figure 3 and Figure 4 , the top end of the guide plate 1 is provided with two texture grooves 15. These texture grooves 15 have important functions. On the one hand, they can store lubricating oil during the working process of the punch, so that the lubricating oil can be evenly distributed on the contact surface of the guide plate and other components, thereby effectively reducing friction and improving the wear resistance and service life of the guide plate. On the other hand, the texture grooves 15 can also enhance the friction of the surface of the guide plate, prevent sliding or displacement during the working process, and ensure the punching precision and stability of the punch. The inside of the guide plate 1 is provided with a bearing assembly for support, which includes a bearing layer 16. The inside of the guide plate 1 is provided with a corrosion-resistant plate 17. The bearing layer 16 and the corrosion-resistant plate 17 partially cooperate with each other, so that the guide plate can maintain good performance in various complex working environments. The corrosion-resistant part can effectively protect the guide plate from the influence of external corrosive factors and prolong the service life of the guide plate.

[0027] The bearing layer 16 is arranged inside the guide plate 1. The material of the bearing layer 16 is carbon fiber reinforced composite material. Carbon fiber reinforced composite material has very high strength and stiffness, which can provide strong support for the guide plate and withstand the huge pressure and impact force generated during the working of the punch without deformation or damage. At the same time, this material also has good fatigue resistance and can maintain stable performance during long-term use, prolonging the service life of the guide plate. In addition, the carbon fiber reinforced composite material is light in weight, which can realize the lightweight design of the guide plate, reduce the operating burden of the punch, improve the production efficiency, and the corrosion-resistant plate 17 is made of aluminum alloy, which can protect the guide plate from erosion in humid, corrosive gas and other harsh environments.

[0028] Working principle: the PTFE coating outside the guide plate 1 greatly reduces the friction coefficient of the guide plate 1 and other components during the work of the punch, reduces the heat generated by friction, reduces the energy loss of the punch, and significantly improves the wear resistance and service life of the guide plate 1. The splicing assembly at the top end of the guide plate 1 plays an important role when connecting adjacent guide plates 1, the connecting plate 2 is connected with the connecting plate 2 of the adjacent guide plate 1 through the bolt 3, ensuring firm and reliable connection, ensuring the stamping precision and stability of the punch. The abutment block 4 on the left and right sides of the guide plate 1 cooperates with the fixed rod 5, when the punch works and generates vibration or impact force, the fixed rod 5 slides in the abutment block 4, absorbs and disperses the force.

[0029] The staff pulls the sliding rod 6 by pulling the disc 7, the sliding rod 6 drives the arc block 8 to slide inside the bottom end of the fixed rod 5, the arc block 8 drives the limiting rod 9 to slide in the inner wall of the bottom end of the fixed rod 5, the limiting rod 9 drives the limiting plate 11 to slide in the containing hole 12, and at the same time, the strong force spring 10 is compressed. When the external force disappears, the strong force spring 10 rebounds, pushes the limiting plate 11 to drive the limiting rod 9 to make the arc block 8 and the sliding rod 6 return to the original position, and in the rebounding process, the outer part of the sliding rod 6 is in contact with the clamping ball 14, and the clamping ball 14 is extruded, so that the clamping ball 14 can only roll in the movable hole 13. In the event of an accident, the clamping ball 14 will not directly come off, but will roll in place, ensuring the stability of the clamping ball 14.

[0030] The texture groove 15 at the top end of the guide plate 1 stores lubricating oil during the work of the punch, which makes the lubricating oil evenly distributed on the contact surface of the guide plate 1 and other components, effectively reducing friction and improving the wear resistance and service life of the guide plate 1. On the other hand, it enhances the surface friction of the guide plate 1, prevents sliding or displacement, and ensures the stamping precision and stability of the punch. The bearing layer 16 and the corrosion-resistant plate 17 inside the guide plate 1 cooperate with each other, the bearing layer 16 is made of carbon fiber reinforced composite material, which provides strong support for the guide plate 1, withstands the huge pressure and impact force generated during the work of the punch without deformation or damage, has good fatigue resistance, maintains stable performance during long-term use, prolongs the service life of the guide plate 1, and at the same time realizes lightweight design, reduces the operating burden of the punch, and improves production efficiency. The corrosion-resistant plate 17 is made of aluminum alloy material, which protects the guide plate 1 from corrosion in humid, corrosive gas and other harsh environments.
