Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a hydraulic punching machine with a protection mechanism. Background Technique

[0002] A hydraulic punching machine is a mechanical device that, after installing raw materials, under the drive of a power mechanism, a punching die acts on the material to complete punching.

[0003] For example, a hydraulic punching machine with the authorization announcement number of "CN212917220U" clamps the sheet through a clamping device to restrict the movement of the sheet, thereby effectively avoiding the offset of the sheet during punching and improving the punching accuracy. However, for this hydraulic punching machine, when the punching column performs hydraulic punching on the material, since the punching column directly punches the material without any protection around it, it increases the risk of workers being injured during work, thus increasing the work danger. At the same time, for this hydraulic punching machine, during the hydraulic punching work, workers need to frequently rotate the crank to fix the material to be punched, thus increasing the workload of the workers. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that there is no protection when the punching column performs hydraulic punching on the material, which increases the risk of workers being injured during work, thereby increasing the work danger, and workers need to frequently rotate the crank to fix the material to be hydraulically punched, thus increasing the workload of the workers, and to propose a hydraulic punching machine with a protection mechanism.

[0028] Working principle:

[0029] Process of hydraulic punching of materials:

[0030] When it is necessary to perform hydraulic punching on materials, the worker places the materials to be hydraulically punched on the workbench 10. Then, connect the external power supply of the second motor 302 and start it. The second motor 302 drives the worm 303 to rotate. The worm 303 drives the worm wheel 304 to rotate. The worm wheel 304 drives the rod body 305 to rotate clockwise (as Figure 5) The rollers on the surface of the rod body 305 drive the relative movement of the two slide rods 306 through the chute. The slide rods 306 drive the block 9 to move. After the two blocks 9 are in contact with the surface of the material to be hydraulically punched, the second motor 302 is turned off. According to the above method, the second motor 302 rotates in reverse to drive the block 9 to reset, and the material to be hydraulically punched is fixed in the above way;

[0031] Then, connect the external power supply of the first motor 202 and start it. The first motor 202 drives the sprocket 203 to rotate. One sprocket 203 drives the other sprocket 203 to rotate synchronously through the chain 204. The sprocket 203 drives the threaded rod 206 to slide downward in the first housing 201 (as Figure 3 ), the nut 206 drives the two plate bodies 4 to move downward until they are in contact with the workbench, and then the first motor 202 is turned off. According to the above method, the first motor 202 rotates in reverse to drive the plate body 4 to reset. The plate body 4 is lowered in the above way to isolate it from the material to be hydraulically punched, reducing the risk of workers being injured during work;

[0032] Connect the external power supply of the hydraulic cylinder 5 and start it. The hydraulic cylinder 5 drives the punching column 6 to move downward. The surface of the punching column 6 contacts the material to be hydraulically punched to perform the hydraulic punching work. After the material to be hydraulically punched is completed with hydraulic punching, the punching column 6, the plate body 4 and the block 9 are reset in the above way. After the punching column 6, the plate body 4 and the block 9 are reset, the hydraulic cylinder 5, the first motor 202 and the second motor 302 are turned off. Finally, the worker takes out the material after hydraulic punching. The hydraulic punching work of the material is completed in the above way.
