Description

Technical Field

[0001] The present application relates to the technical field of punching machines, and in particular to a punching machine. Background Art

[0002] A punching machine is a mechanical device used to create holes or complex cuts in sheet metal or other materials. It typically does this by pressing a punch into the workpiece along a predetermined path. Punching machines can be used standalone or as part of a CNC machine, operating automatically according to a pre-programmed process.

[0003] The existing Chinese patent with announcement number CN219335582U discloses a punching machine, including a punching table, a punching head fixedly connected to the bottom of the hydraulic cylinder, a threaded rod movably sleeved on the inner sides of the two support plates, and a positioning plate is threadedly sleeved on the outer sides of the No. 1 and No. 2 threads. The front of the threaded rod is fixedly connected to the No. 1 handle, and the right side of the top of the top of the top plate is movably sleeved with a positioning rod, and the top of the positioning rod is fixedly connected to the No. 2 handle. The bottom of the lifting tube is fixedly connected to the lifting plate. Turn the No. 1 handle clockwise, and the two positioning plates move closer to the inside, and then turn the No. 2 handle clockwise until the No. 2 roller is tightly fitted with the top of the bracket. By clamping the positioning plate and pressing the top lifting plate, the position of the bracket to be punched is fixed, so that no offset occurs during the punching process, and it can adapt to the positioning of brackets of different sizes.

[0004] However, the above-mentioned punching machine has the following disadvantages: the device fixes the punching bracket by setting a positioning plate, but the device has only one punching head to punch the workpiece, which cannot adapt to the processing needs of holes of different shapes. If different holes are required, it needs to be frequently disassembled and replaced, which reduces the flexibility of the equipment.

[0030] The implementation principle of a punching machine in an embodiment of the present application is as follows: when in use, the workpiece to be punched can be placed on the conveyor belt 9, and then the first motor 8 is started, the first motor 8 drives the active roller to rotate, the active roller drives the conveyor belt 9 to rotate, the conveyor belt 9 drives the driven roller to rotate, and then the workpiece is transported to the bottom of the support frame 3, and then the two first hydraulic cylinders 2 are started, the two first hydraulic cylinders 2 push the clamping plate 7 close to the workpiece to clamp the workpiece, and at the same time the second motor 21 is started, the second motor 21 drives the screw 20 to rotate, the screw 20 drives the fixed plate 16 to move downward, the fixed plate 16 drives the damper 17 to move downward, the damper 17 drives the pressure plate 18 to move downward to press the workpiece, and then the second hydraulic cylinder 5 is started, the second hydraulic cylinder 5 head pushes the mounting frame 4 downward, the mounting frame 4 drives the mounting seat 6 and the punching head 13 to move downward to punch the workpiece, and the damper 17 can punch the holes The impact force is buffered when the punching head 13 is replaced. When a different punching head 13 needs to be replaced, the knob 26 can be manually held and the fixed shaft 10 can be pulled out. The fixed shaft 10 drives the limit block 25 to move out of the limit slot 24, so that the insert block 12 moves out of the slot 23, releasing the lock of the rotating shaft 22 and the fixed shaft 10. Then the knob 26 is rotated, the knob 26 drives the fixed shaft 10 to rotate, the fixed shaft 10 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the mounting seat 6 to rotate, and the mounting seat 6 drives the punching head 13 to rotate, thereby adjusting the required punching head 13, and then pushing the knob 26 inward, the knob 26 drives the fixed shaft 10 to move inward, the fixed shaft 10 drives the insert block 12 to move into the slot 23, thereby locking the rotating shaft 22 and preventing the rotating shaft 22 from rotating. The punched waste enters the collection box through the through hole and then falls into the drawer 15. The drawer 15 can be pulled out and processed.
