When the output ends of the two electric hydraulic rods 10 simultaneously push the lifting plate 8 down, the T-shaped pressure rod 901 in the middle position of the lifting plate 8 first presses on the top of the placing plate 3, and through the downward movement of the placing plate 3, the four positioning components 6 evenly distributed around the side walls of the placing plate 3 center and clamp the hard rubber seal 5, and through the continued downward movement of the lifting plate 8, when the bottom of the placing plate 3 moves to the top of the supporting ring 103, the placing plate 3 stops moving downward, and the punching heads 12 evenly distributed along the circumference of the bottom of the fixing ring 11 punch the hard rubber seal 5, and the T-shaped pressure rod 901 is squeezed and moved upward, and the second return spring 903 is squeezed and contracted by force, and the punched waste falls from the bottom of the circular groove 101 through the avoidance hole 301, which is convenient for subsequent cleaning. In addition, a collection box can be placed at the bottom of the workbench 1 to collect the fallen waste. Through this automatic centering and clamping method, the processing efficiency of rubber seals can be further improved.

Please refer to FIG1 . In this embodiment, six balls are installed at equal intervals along the circumference of both ends of the lifting plate 8, and the surface of the balls is placed on the surface of the support column 7. Through the arrangement of the balls, the sliding installation between the lifting plate 8 and the support column 7 is transformed into a rolling installation, which reduces the contact area between the two, reduces the friction, and further improves the lifting stability of the lifting plate 8.

Please refer to FIG. 1 . In this embodiment, the bottom of the workbench 1 is symmetrically provided with openings 102, and the top of the openings 102 is connected to the bottom of the circular groove 101. After the punching head 12 punches the surface of the hard rubber seal 5, the waste material falls to the bottom of the workbench 1 through the openings 102 at the bottom of the circular groove 101, so as to avoid the waste material from accumulating inside the circular groove 101 and affecting the use of the device.

Working principle: turn on the power supply, and in the process of punching the hard rubber seal 5, first place the hard rubber seal 5 on the top of the placement disk 3, start the electric hydraulic rod 10, and push the lifting plate 8 downward synchronously through the output ends of the two electric hydraulic rods 10. The T-shaped pressure rod 901 in the middle position of the lifting plate 8 is first pressed on the top of the placement disk 3. Through the downward movement of the placement disk 3, the first return spring 4 is squeezed and contracted by force. At the same time, the inclined surfaces of the pressure blocks 605 at the bottom of the four movable sleeves 602 equidistantly distributed along the circumference are squeezed on the conical surface of the circular groove 101, so that the movable sleeve 602 moves in the direction of the placement disk 3. At the same time, the push block 604 is pressed against the side wall of the hard rubber seal 5 by moving, and the four equidistantly distributed push blocks 604 are pressed synchronously. The side wall of the hard rubber seal 5 enables the hard rubber seal 5 to realize automatic centering and clamping positioning. By continuing to move the lifting plate 8 downward, when the bottom of the placement plate 3 moves to the top of the support ring 103, the placement plate 3 stops moving downward, and the punching heads 12 distributed equidistantly along the circumference of the bottom of the fixed ring 11 punch the hard rubber seal 5. After the punching is completed, the electric hydraulic rod 10 drives the lifting plate 8 to move upward, and the placement plate 3 contacts and presses, so that the first reset spring 4 is elastically reset after being stressed, and pushes the placement plate 3 to automatically move out of the circular groove 101, and the telescopic spring 603 pushes the movable sleeve 602 to move away from the placement plate 3 for reset, and the push block 604 automatically releases the fixation of the hard rubber seal 5, which facilitates the removal of the hard rubber seal 5.
