DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a mechanical stamping device for convenient replacement of a stamping head includes a frame 1 and a stamping table 5. The frame 1 is fixedly installed on the top of the stamping table 5. A hydraulic cylinder 2 is fixedly installed on the top of the stamping table 5. A mounting seat 3 is fixedly installed on the telescopic end of the hydraulic cylinder 2, and a limiting component is installed on the mounting seat 3.

[0022] The limiting assembly includes a limiting plate 13, and connecting blocks 20 are fixedly installed on the left and right sides of the limiting plate 13. A movable rod 17 is fixedly connected to the top of the connecting block 20, and a circular block 18 is fixedly installed on the top of the movable rod 17. A spring 7 is sleeved on the outside of the movable rod 17. Fixed blocks 6 are fixedly installed on the left and right sides of the mounting seat 3. The movable rod 17 is slidably connected to the inside of the fixed block 6. A locking piece is installed on the fixed block 6. The locking piece includes a threaded column 15 and a rotating head 8. The rotating head 8 is fixedly connected to one side of the threaded column 15. A threaded groove 14 is provided on the inner wall of the fixed block 6, and a circular hole is provided inside the movable rod 17. The end of the threaded column 15 close to the mounting seat 3 passes through the fixed block 6 and the circular hole in sequence and is threadedly connected to the inside of the threaded groove 14.

[0023] It should be noted that the threaded column 15 can be conveniently rotated by the rotating head 8. When the punch head 4 needs to be disassembled, the rotating head 8 is rotated to rotate the threaded column 15 out of the thread groove 14, and the threaded column 15 is moved out of the round hole, so that the circular block 18 can be pushed to move downward, thereby pushing the limit plate 13 to move downward and separate from the mounting seat 3, and the positioning rod 10 is moved out of the positioning groove 12. When the limit plate 13 is moved to the bottom of the punch head 4, the insert block 11 can be pulled out of the slot 19, thereby removing the punch head 4, which is convenient for replacement when the punch head 4 is damaged.

[0024] In this embodiment, a slot 19 is provided at the bottom of the mounting base 3, and an embedding slot 16 is provided inside the mounting base 3 and is located on the left and right sides of the slot 19. An insert block 11 is clamped inside the slot 19, and the left and right sides of the insert block 11 are fixedly connected with embedding blocks 9, which are clamped inside the embedding slot 16. A punch head 4 is fixedly installed at the bottom of the insert block 11, and the bottom of the punch head 4 extends to the outside through the center hole on the limit plate 13.

[0025] The two embedded blocks 9 are provided to position the slot 19 , so that after the insert block 11 is inserted into the slot 19 , the positioning rod 10 can always be aligned with the positioning groove 12 .

[0026] In this embodiment, the limit plate 13 is in a circular ring shape, and the left and right sides of the top of the limit plate 13 are fixedly connected with positioning rods 10, and the left and right sides of the bottom of the plug block 11 are provided with positioning grooves 12. The positioning rod 10 is inserted into the positioning groove 12, and the limit plate 13 is in contact with the bottom of the mounting seat 3, and the mounting seat 3 is a cylindrical structure.

[0027] It is understandable that by setting the limiting plate 13 to be a circular ring structure, the bottom of the punching head 4 can pass through the limiting plate 13 .

[0028] In this embodiment, the spring 7 is fixedly connected between the circular block 18 and the fixed block 6, and the cross section of the movable rod 17 is square.

[0029] It should be noted that, by providing the spring 7 , when the circular block 18 is pressed downward, the limiting plate 13 will be pushed to move downward, so that the limiting plate 13 is away from the mounting seat 3 .

[0030] The working principle of the above embodiment is as follows: when in use, the rotating heads 8 on both sides are rotated respectively to drive the threaded column 15 to rotate. After the threaded column 15 is taken out from the movable rod 17, the circular block 18 can be pressed downward, which will squeeze the spring 7 to make it expand and contract, thereby pushing the limit plate 13 to move downward and separate from the mounting seat 3. At the same time, the positioning rod 10 is pulled out of the positioning groove 12. After the limit plate 13 moves to the bottom of the punching head 4, the punching head 4 can be pulled downward to pull the insert block 11 out of the slot 19, and the embedded block 9 can be moved out of the embedded groove 16. After that, the punching head 4 and the insert block 11 can be taken out from the gap between the positioning groove 12 and the mounting seat 3, thereby facilitating the disassembly and replacement of the punching head 4.
