DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a punching device that is easy to replace a punching head, including a punching machine 1, a punching cylinder 3 and a punching head 4. The bottom of the punching cylinder 3 is provided with a control unit 2 that is easy to replace the punching head 4. The control unit 2 includes:

[0023] The top surface of the connecting column 21 is fixedly connected to the output shaft of the punching cylinder 3. The bottom surface of the connecting column 21 is fixedly connected to the knife seat 22. The top surface of the knife seat 22 is fixedly connected to the hinge plate 23. The inner side of the hinge plate 23 passes through and is hingedly connected to a rotating hook 24. The side of the knife seat 22 is fixedly connected to a positioning piece 25. The inner side of the positioning piece 25 passes through and is slidably connected to an insertion rod 26. The insertion rod 26 passes through and is fixedly connected to a circular piece 27. A spring 28 is fixedly connected between the top surface of the circular piece 27 and the bottom surface of the positioning piece 25. A movable groove 29 is opened on the side of the knife seat 22. A linkage plate 210 passes through and is rotatably connected to the interior of the knife seat 22. The bottom surface of the linkage plate 210 is opened with a toggle groove 211. A connecting rod 222 is fixedly connected to the side of the linkage plate 210. The connecting rod 222 passes through the movable groove 29, and the end of the connecting rod 222 away from the linkage plate 210 is fixedly connected to the torsion ring 212. A limiting hole 213 is provided on the surface of the torsion ring 212. Pressing the rotating hook 24 downward causes the rotating hook 24 to rotate on the inner side of the hinge plate 23, and the rotating hook 24 will hook the protruding part of the top of the insertion rod 26, so that the insertion rod 26 will be pulled up and drive the disc 27 to compress the spring 28, and at the same time the insertion rod 26 will no longer be inserted into the limiting hole 213. A limiting disk 214 is fixedly connected to the inner side of the knife holder 22. A slider 215 is inserted through the inner side of the limiting disk 214 and slidably connected thereto. Rotating the torsion ring 212 causes the torsion ring 212 to drive the connecting rod 222 to rotate within the movable groove 29. Simultaneously, the connecting rod 222 drives the linkage plate 210 within the knife holder 22 to rotate. When the linkage plate 210 rotates, the toggle groove 211 is also rotated and the toggle rod 217 is toggled. The toggle rod 217 drives the slider 215 away from the center of the knife holder 22 along the limiting rod 216. The top surface of the slider 215 is fixedly connected to the toggle rod 217, and the top end of the toggle rod 217 is inserted into the toggle groove 211. A limiting rod 216 is fixedly connected to the inner side of the limiting disk 214. The limiting rod 216 passes through the slider 215 and is slidably connected thereto. A spring 219 is fixedly connected between the slider 215 and the inner side of the limiting disk 214, and a locking block 218 is fixedly connected to the bottom surface of the slider 215. The torsion ring 212 is loosened, so that the linkage plate 210 is no longer affected by external forces. Further, the slider 215 is also no longer disturbed by external forces. Then the compressed spring 219 will push the slider 215 to reset, so that the six groups of locking blocks 218 will clamp the punch head 4. When the punch head 4 is loosened, the compressed spring 3 220 will also push the pressure plate 221 to clamp the punch head 4 and the locking block 218. The locking block 218 passes through the limiting disk 214 and is slidably connected. A pressure plate 221 passes through and is fixedly connected to the inner side of the connecting column 21. A spring three 220 is fixedly connected between the top surface of the pressure plate 221 and the inner side of the connecting column 21. When the slider 215 slides, the spring two 219 is also compressed. After the locking block 218 is tightened in the limiting disk 214, the punch head 4 is taken out and inserted into the tool holder 22 and pushed upward, so that the punch head 4 pushes the pressure plate 221 to compress the spring three 220.

[0024] When the lever 215 is in the locked position, the spring 28 is released and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, and the locking member 218 is engaged, 219 is compressed, and after the locking block 218 is tightened in the limiting disk 214, the punch head 4 is taken and inserted into the tool holder 22 and pushed upward, so that the punch head 4 pushes the pressure plate 221 to compress the spring three 220, and then the torsion ring 212 is loosened, so that the linkage plate 210 is no longer affected by the external force, and the slider 215 is no longer disturbed by the external force. Then the compressed spring two 219 will push the slider 215 to reset, so that the six sets of locking blocks 218 clamp the punch head 4. , release the punch head 4, the compressed spring three 220 will also push the pressure plate 221 to clamp the punch head 4 and the locking block 218, and then release the rotating hook 24, and reinsert the insertion rod 26 into the limiting hole 213 through the compressed spring one 28 so that the entire control part 2 can stably fix the punch head 4, and the punch head 4 can be fixed in the horizontal and vertical directions at the same time by rotating and loosening the torsion ring 212. The convenient operation makes the replacement and installation of the punch head 4 more efficient.

[0025] At the same time, the locking blocks 218 of the circular array can fix the punching heads 4 of different diameters, and the mounting plates of different thicknesses of the punching heads 4 can also be locked through the continuous pressing of the pressure plate 221, which has a wider range of applications and is more convenient and efficient to use.
