The top surface of the machine body 1 is fixedly mounted with a first fixed frame 20 and a second fixed frame 24. A punching die 24 is installed. Two support plates 22 are fixedly mounted on the top surface of the machine body 1. A guide rail 19 is fixedly mounted on the top surface of the machine body 1 between the two support plates 22. A movable block 26 is slidably mounted on the guide rail 19. A second screw 21 is rotatably mounted between the two support plates 22 and is threadedly connected to the movable block 26. A support arm 18 is fixedly mounted on the top surface of the movable block 26. An isolation plate 17 is fixedly mounted on one side surface of the support arm 18. A transmission mechanism is provided on one side surface of the first fixed frame 20. The transmission mechanism enables the movable block 26 and the movable frame 10 to move towards each other or away from each other. The driving mechanism includes a drive pulley 14, a first screw 11 with one end passing through a first fixed frame 20 and fixedly connected to the drive pulley 14, a second driven pulley 25 and a guide wheel 16 rotatably mounted on one side surface of the first fixed frame 20, a second screw 21 with one end passing through a support plate 22 and fixedly mounted on a first driven pulley 23, the drive pulley 14, the first driven pulley 23 and the second driven pulley 25 meshing together with a belt 15, the outer surface of the belt 15 contacting the guide wheel 16; a first limiting ring 13 and a second limiting ring 9 are fixedly mounted on the side surface of the guide beam 12; and a liquid is fixedly mounted inside the mounting frame 6. The hydraulic cylinder 7 has its telescopic end penetrating the bottom surface of the mounting frame 6. The telescopic end of the hydraulic cylinder 7 is fixedly provided with a mounting part 4, and the bottom surface of the mounting part 4 is fixedly installed with a punching upper die 3. Multiple guide rods 5 are fixedly provided on the top surface of the mounting part 4, and the guide rods 5 are slidably connected to the lower wall of the mounting frame 6. A servo motor 8 is fixedly installed on the outer surface of the second fixed frame 2. One end of the first screw 11 passes through the second fixed frame 2 and is fixedly connected to the drive shaft of the servo motor 8. The isolation plate 17 is made of transparent material. The thread direction of the first screw 11 is opposite to the thread direction of the second screw 21. The punching lower die 24 matches the punching upper die 3.
[0023] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0024] When in use, the worker places the object to be punched on the lower punching die 24. At this time, the upper punching die 3 is located to the upper right of the lower punching die 24, ensuring the safety of the worker when placing the object to be punched.
[0025] Starting the servo motor 8 drives the first screw 11 to rotate. The rotation of the first screw 11 drives the drive pulley 14 to rotate. The rotation of the drive pulley 14 drives the belt 15 to rotate. The rotation of the belt 15 drives the first driven pulley 23 to rotate. The rotation of the first driven pulley 23 drives the second screw 21 to rotate. The simultaneous rotation of the first screw 11 and the second screw 21 drives the movable frame 10 and the movable block 26 to move towards each other, thereby causing the upper punching die 3 and the isolation plate 17 to move towards each other. When the movable frame 10 contacts the first limit ring 13, the upper punching die 3 is located directly above the lower punching die 24. At the same time, the isolation plate 17 isolates the worker from the punching processing area, effectively ensuring the worker's personal safety during punching. The extension of the hydraulic cylinder 7 drives the mounting part 4 to descend. The descent of the mounting part 4 drives the upper punching die 3 to descend and punch the workpiece. The upper punching die 3 and the lower punching die 24 are existing technologies and will not be described here.
[0026] After the punching is completed, the hydraulic cylinder 7 shortens to drive the upper punching die 3 to rise, and the servo motor 8 reverses to drive the first screw 11 and the second screw 21 to rotate in opposite directions, so that the movable frame 10 and the movable block 26 move in opposite directions, and thus the upper punching die 3 and the isolation plate 17 move in opposite directions. When the movable frame 10 contacts the second limit ring 9, the upper punching die 3 and the isolation plate 17 are reset.
[0027] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
