Two lubricating oil tanks 801 are fixedly installed on the upper end of the top plate 6, and the two top plates 6 are symmetrically arranged about the hydraulic cylinder 7. A mounting groove 802 is opened inside the top plate 6. Second rectangular grooves 803 are opened on both the front and rear sides of the mounting groove 802. A lubricating oil impregnated cotton plate 810 is arranged inside the mounting groove 802. The lubricating oil impregnated cotton plate 810 is made of cotton fiber and is placed at the connection between the output end of the hydraulic cylinder 7 and the telescopic sleeve 9 to increase its lubrication performance and wear resistance. A connecting pipe 805 is arranged inside the second rectangular groove 803. The front and rear ends of the lubricating oil impregnated cotton plate 810 are respectively connected to the hydraulic cylinder 7. The two connecting pipes 805 are connected, and the upper sides of the outer surfaces of the two connecting pipes 805 are fixedly connected with the first oil outlet pipe 804. The upper end of the first oil outlet pipe 804 is connected with the interior of the lubricating oil tank 801. The lower side of the outer end of the connecting pipe 805 is fixedly connected with the second oil outlet pipe 806. The second oil outlet pipe 806 passes through the bottom plate of the second rectangular groove 803 and is fixedly connected with the oil outlet head 807. The outer surface of the connecting pipe 805 is fixedly installed with a first valve 808 and a second valve 809. The position where the first oil outlet pipe 804 is connected to the connecting pipe 805 is located on the outside of the first valve 808 and the second valve 809. On the inner side of the door 809, the first valve 808 controls the lubricating oil to flow to the lubricating oil impregnated cotton plate 810, and the second valve 809 controls the lubricating oil to flow to the oil outlet head 807. The output end of the hydraulic cylinder 7 extends to the inside of the lubricating oil impregnated cotton plate 810 and is fixedly connected to the telescopic sleeve 9. The released lubricating oil will form a thin film at the connection between the output end of the hydraulic cylinder 7 and the telescopic sleeve 9. When the hydraulic cylinder 7 moves, this thin film will form a lubricating film on the contact surface of the connection to reduce friction and wear, thereby extending the service life of the connecting parts. The lower end of the telescopic sleeve 9 is fixedly connected to a movable plate 10.

[0029] Reference Figure 1 , Figure 2 and Figure 5As shown, a stamping punch 12 is fixedly installed at the lower end of the movable plate 10, and an infrared transmitter 13 is provided at the lower end of the movable plate 10 and the left side of the stamping punch 12. Slide blocks 11 are fixedly connected to the front and rear ends of the movable plate 10, and the slide blocks 11 are slidably connected to the inside of the slide groove 5. A support plate 15 is fixedly installed at the middle part of the upper end of the base 1, and a first rectangular groove 2 is provided on the left side of the support plate 15 and the upper end of the support plate 15. An infrared receiver 3 is provided inside the first rectangular groove 2. The infrared transmitter 13 and the infrared receiver 3 cooperate with each other.

The two connecting plates 1405 extend out of the mounting frame 1401 through the two rectangular openings 1403 respectively and are fixedly connected to a pressing plate 1406. The metal sheet to be processed is fixed by the pressing plate 1406 to prevent the moving or shaking metal sheet from losing control of the processing trajectory, resulting in defective products or defects during the processing.

[0030] The working principle and use process of the utility model are as follows: when in use, the metal sheet to be processed is placed on the upper end of the support plate 15, the electric telescopic rod 1402 drives the movable plate 1404 to slide inside the installation frame 1401, and the connecting plate 1405 inside the movable plate 1404 drives the pressing plate 1406 to fix the metal sheet by sliding in the rectangular opening 1403. After the fixation is completed, the controller 16 controls the hydraulic cylinder 7 to drive the telescopic sleeve 9 to move downward, and the telescopic sleeve 9 drives the movable plate 10 to move downward.

In the process of stamping the metal sheet, the controller 16 controls the two first valves 80 8 is opened. After the two first valves 808 are opened, the lubricating oil in the lubricating oil tank 801 flows through the first oil outlet pipe 804 and the connecting pipe 805 to the lubricating oil impregnated cotton plate 810, and the lubricating oil impregnated cotton plate 810 is used to lubricate the connection between the output end of the hydraulic cylinder 7 and the telescopic sleeve 9, thereby reducing the friction coefficient between the output end of the hydraulic cylinder 7 and the telescopic sleeve 9, thereby reducing energy loss and wear, and improving the working efficiency and response speed of the device. As needed, the controller 16 controls the second valve 809 to open, and the lubricating oil in the lubricating oil tank 801 is transported through the first oil outlet pipe 804, the connecting pipe 805 and the second oil outlet pipe 806, and finally flows into the slide groove 5 through the oil outlet head 807, thereby reducing the friction between the slide groove 5 and the slider 11.

[0031] During the process of the hydraulic cylinder 7 punching the metal sheet, if the worker puts his hand into the punch press, due to the cooperation between the infrared transmitter 13 and the infrared receiver 3, the worker's hand will block the infrared rays, so that the infrared receiver 3 cannot receive the infrared rays. Then the hydraulic cylinder 7 will not drive the telescopic sleeve 9 to move, and then will not punch the metal sheet, thereby improving the safety of the device and avoiding harm to the workers.
