In the process of producing the trolley, it is usually necessary to use a punching machine to punch the trolley for assembly of the trolley case. The punching machine is a mechanical equipment used to punch the trolley. After the hollow tube used to make the trolley is installed on the workbench of the punching machine, the punch is driven by the power mechanism to act on the trolley to complete the punching. According to the shape of the processed material, the punching machine is divided into flat plate punching machine, round tube punching machine, square tube punching machine and U-shaped steel punching machine.

It is necessary to stop the machine and manually adjust the position of the tie rod to make the next hole position correspond to the punch so as to continue punching the next hole position. This is inconvenient to operate and reduces work efficiency. In addition, it cannot stably fix tie rods of different diameters. At the same time, the tie rod may have positional offset problems when punching, which affects the accuracy of the hole position on the tie rod and makes the tie rod unusable for assembly and has low practicality.

DETAILED DESCRIPTION
[0016] Reference Figures 1 to 3 The embodiments of the present invention are further described.
[0017] A punching machine for producing tie rods includes a machine body 1 and a punch 2 mounted on the machine body 1 for punching a tie rod 1001. The machine body 1 includes a workbench 3 corresponding to the punch 2. A positioning plate 4, a movable plate 5, and a hydraulic cylinder 6 are mounted on the workbench 3. The movable plate 5 is fixedly connected to the hydraulic cylinder 6.
[0018] The movable plate 5 cooperates with the positioning plate 4 to form a positioning space 7 corresponding to the punch 2. The movable plate 5 is provided with a positioning groove 8 connected to the positioning space 7 and a threaded hole 9 connected to the positioning groove 8. The positioning plate 4 is provided with a fixing screw 10 threadedly connected to the threaded hole 9. The fixing screw 10 is installed with a pressing block 11 that cooperates with the outer surface of the pull rod 1001. A movable hole 12 corresponding to the positioning groove 8 is opened on the fixed plate. A fixing rod 13 that cooperates with the pull rod 1001 is fixed in the positioning groove 8. A first elastic block 14 that can interfere with the inner wall of the pull rod 1001 is installed on the fixed rod 13. A second elastic block 15 that can interfere with the outer wall of the pull rod 1001 is installed in the movable hole 12.
[0019] A guide plate 16 is installed on the workbench 3, and a guide channel 17 is opened on the guide plate 16 for cooperating with the pull rod 1001. The hydraulic cylinder 6 drives the movable plate 5 to slide in the guide channel 17. A plurality of clamping members 18 for fixing the pull rod 1001 are installed on the inner wall of the guide channel 17. The plurality of clamping members 18 are relatively arranged on both sides of the guide channel 17. The clamping members 18 are composed of a third elastic block 181 and a fixing plate 182. The two ends of the third elastic block 181 are fixedly connected to the inner wall of the guide channel 17 and the fixing plate 182 respectively. The fixing plate 182 is in contact with the outer wall of the pull rod 1001 for fixing the pull rod 1001. The first elastic block 14, the second elastic block 15 and the third elastic block 181 can be made of elastic rubber material.
[0020] Working principle: Place the pull rod 1001 in the positioning space 7 corresponding to the punch 2, one end of the pull rod 1001 is placed in the positioning groove 8 on the movable plate 5 and plugged into the fixed rod 13 in the positioning groove 8, the first elastic block 14 on the fixed rod 13 contacts the inner wall of the pull rod 1001 to fix the pull rod 1001, rotate the fixing screw 10 to make the pressing block 11 contact the outer surface of the pull rod 1001, thereby further fixing the pull rod 1001 on the movable plate 5, the other end of the pull rod 1001 is placed in the movable hole 12 and contacts the second elastic block 15 in the movable hole 12, so that the second elastic block 15 further fixes the pull rod 1001. 1 is fixed, thereby preventing the position of the tie rod 1001 from shifting when the punch 2 punches the tie rod 1001. Since the first elastic block 14 and the second elastic block 15 are elastic, they can automatically adjust the deformation according to the different diameters of the tie rod 1001 to adapt to the different diameters of the tie rod 1001 and conflict with the tie rod 1001, thereby stably fixing the tie rods 1001 with different diameters. In addition, the third elastic block 181 is squeezed and deformed by the tie rod 1001 to generate elastic force, causing the fixing piece 182 to conflict with the tie rod 1001 to further fix the tie rod 1001, further preventing the position of the tie rod 1001 from shifting when the punch 2 punches the tie rod 1001.
[0021] Cooperating with the hydraulic cylinder 6, the movable plate 5 is driven to slide in the guide channel 17 so that the movable plate 5 moves toward the fixed plate, so that the pull rod 1001 fixed on the movable plate 5 moves away from the hydraulic cylinder 6, which facilitates the punch 2 to punch holes at different positions of the pull rod 1001. While the pull rod 1001 moves, the pull rod 1001 moves in the movable hole 12 and the guide channel 17, and the second elastic block 15 in the movable hole 12 slides on the surface of the pull rod 1001 so that the second elastic block 15 contacts the outer wall of the pull rod 1001 to fix the pull rod 1001 and prevent the pull rod 1001 from deflecting without affecting the movement of the pull rod 1001. The fixed plate 182 slides on the surface of the pull rod 1001 so that the third elastic block 181 cooperates with the fixed plate 182 to further fix the pull rod 1001. It will not affect the movement of the pull rod 1001, and one end of the pull rod 1001 is always stably fixed on the movable plate 5 during the movement of the pull rod 1001, so that the pull rod 1001 is stably fixed in the positioning space 7 when the punch 2 punches holes at different positions of the pull rod 1001, avoiding the position deviation of the pull rod 1001 when the punch 2 punches holes at different positions of the pull rod 1001. Finally, it is achieved that the pull rod 1001 can be automatically moved to a position corresponding to the punch 2, which is convenient for the punch 2 to punch holes at different positions of the pull rod 1001. It is easy to operate and improves work efficiency. It can stably fix the pull rods 1001 of different diameters while avoiding the problem that the position deviation of the pull rod 1001 when the punch 2 punches holes affects the accuracy of the hole position on the pull rod 1001, resulting in the pull rod 1001 being unable to be used for assembly and cannot be used, thereby improving practicality.
