[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figures 1 to 12As shown, a marking machine punch includes: a base 2, which is connected to the punching arm 1 of the marking machine; a mounting block 4, which has an insertion hole 402 and a punching block 5 inside the insertion hole 402; the mounting block 4 is movably connected to the base 2; the punching block 5 has a first mounting hole 501 and a second mounting hole 404 corresponding to the first mounting hole 501; a pin 9 passes through the second mounting hole 404 and the first mounting hole 501 in sequence; and a support column 11, one end of which contacts the end face of the mounting block 4 near the base 2, and the other end of which is provided with a compression spring 12 between it and the base 2.

[0045] There are 8 stamping blocks 5. The stamping group composed of 8 stamping blocks 5 matches the insertion hole 402. The length direction of the stamping block 5 is set along the moving direction of the mounting block 4. The end face of the stamping block 5 away from the base 2 is provided with a boss with a stamping symbol.

[0046] A guide post 1101 is fixedly installed at the end of the support post 11 away from the mounting block 4. The base 2 has a mounting groove 202 corresponding to the support post 11. A third mounting hole 203 is opened at the bottom of the mounting groove 202. A retaining ring 10 is provided in the third mounting hole 203. The inner diameter of the retaining ring 10 matches the diameter of the guide post 1101. The guide post 1101 is installed inside the retaining ring 10. The compression spring 12 is located between the retaining ring 10 and the guide post 1101. The diameter of the guide post 1101 is smaller than the diameter of the support post 11, and the diameter of the third mounting hole 203 is smaller than the diameter of the support post 11. There are two support posts 11. A damping assembly is provided between the compression spring 12 and the retaining ring 10. The damping assembly can be a hydraulic damper or a rubber pad. It is worth noting that the stamping operation in this embodiment is low-frequency vibration reduction, and a buffering effect can be achieved without using a damper.

[0047] The depth of the mounting groove 202 is greater than the height of the support column 11. During the stamping operation, as the compression spring 12 is compressed, the support column 11 will be completely located inside the mounting groove 202, and the base 2 will directly contact the mounting block 4 or the positioning plate 3 to provide pressure.

[0048] The third mounting hole 203 has an internal thread on the inner side of the end away from the mounting groove 202, and the retaining ring 10 has an external thread on the outer side. The retaining ring 10 is threaded to the inner side of the third mounting hole 203. Rotating the retaining ring 10 can adjust the length of the compression spring 12 and thus adjust the elastic force of the compression spring 12.

[0049] A hexagonal groove 1001 is provided on the end face of the retaining ring 10 away from the compression spring 12, which facilitates the rotation of the retaining ring 10.

[0050] The base 2 has side plates 6 on both sides. The side plates 6 have strip holes 602 that are set along the moving direction of the mounting block 4. The mounting block 4 has a first threaded hole 403 that corresponds to the strip hole 602. The guide bolt 8 passes through the strip hole 602 and is threaded to the inside of the first threaded hole 403. The width of the strip hole 602 is greater than the diameter of the guide bolt 8. The guide bolt 8 moves in the strip hole 602. In the stamping state, the end of the strip hole 602 away from the base 2 limits the guide bolt 8.

[0051] The base 2 has a second threaded hole 201 on its side, and the side plate 6 has a through hole 601 corresponding to the second threaded hole 201. The connecting bolt 7 passes through the through hole 601 and is threaded to the inside of the second threaded hole 201. Both sides of the base 2 have two second threaded holes 201. The side plate 6 is detachably connected to the base 2 by the connecting bolt 7, which makes it easy to remove the side plate 6 and replace the stamping block 5.

[0052] In another embodiment, a positioning plate 3 is provided between the support column 11 and the mounting block 4. The positioning plate 3 has a positioning groove 301 on the end face of the mounting block 4 adjacent to the positioning plate 3. The mounting block 4 has a positioning boss 401 that matches the positioning groove 301 on the end face of the mounting plate 3 adjacent to the positioning plate 3. The positioning boss 401 is located inside the positioning groove 301. The positioning groove 301 plays a positioning role for the positioning boss 401. The positioning plate 3 plays a role in isolating the support column 11 and the mounting block 4, preventing the support column 11 from directly contacting the mounting block 4, and also plays a role in supporting the stamping block 5.

[0053] The end face of the stamping block 5 near the positioning plate 3 is in contact with the positioning plate 3. During the stamping operation, the positioning plate 3 is subjected to force, and the pin 9 only plays a positioning role, which prevents the pin 9 from deforming.

[0054] The stamping arm 1 has a mounting groove 101 that matches the base 2. The base 2 is installed inside the mounting groove 101. The positioning plate 3 and the mounting block 4 are at the same height as the base 2 and are both located inside the mounting groove 101. A third threaded hole is opened on the end face of the base 2 near the bottom of the mounting groove 101. A connecting hole 103 corresponding to the third threaded hole is opened at the bottom of the mounting groove 101. The mounting bolt passes through the connecting hole 103 and is threaded to the inside of the third threaded hole. An adjustment hole 102 corresponding to the support column 11 is opened at the bottom of the mounting groove 101. The adjustment hole 102 corresponds to the position of the retaining ring 10, which facilitates the rotation of the retaining ring 10 and thus adjusts the elastic force of the compression spring 12, making it suitable for different working scenarios.

[0055] Work process:

[0056] When this solution is implemented, as the stamping arm 1 moves toward the rolling direction, the stamping block 5 on the mounting block 4 comes into contact with the rolling steel. At this time, the compression spring 12 is compressed until the positioning plate 3 comes into contact with the base 2. Then, the stamping force of the stamping arm 1 is completely applied to the rolling steel by the stamping block 5. The setting of the compression spring 12 makes the interaction force between the stamping block 5 and the rolling steel gradually increase. Compared with the existing method of directly reaching the maximum value, this reduces the wear of the stamping block 5 and the replacement cycle of the stamping block 5, thereby reducing production costs.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
