As shown in fig. 1 to 4, the utility model provides a jig for punching a ring fixing hole of a watchband, which comprises an upper die 1 and a lower die 2;

The lower die 2 is provided with a placing groove 21 for the watchband to be placed vertically, a first perforation 22 penetrating through the inner bottom surface of the placing groove to the lower surface of the lower die is formed in the placing groove 21, the upper die comprises a fixed block 11, a thimble 12 is mounted on the fixed block, the thimble 12 extends towards the direction of the lower die 2, and the position of the thimble 12 is aligned with the position of the first perforation 22.

In this embodiment, during processing, firstly, the leather watchband is placed in the placement groove 21, the size of the placement groove 21 is matched with that of the leather watchband, so that after the leather watchband is placed in the placement groove, the leather watchband is tightly contacted with the placement groove 21, the leather watchband is not easy to shake, and the position of the leather watchband, which needs to be ejected, is aligned with the first perforation 22; secondly, the depth of the placing groove 21 needs to be larger than the width of the leather watchband, so that the leather watchband is not easy to deflect after being stressed, and the processing precision and the yield of products are effectively improved; then the upper die 1 is driven by the driving device to approach the lower die 2, the fixing block 11 of the upper die 1 pushes the thimble 12, the thimble 12 is firstly contacted with the watchband until penetrating the first perforation 22, and then the plastic part in the leather watchband is completely ejected out, so that the leather watchband forms a fixing perforation for fixing with the fixing ring, and the whole processing process is completed.

In some embodiments, the top end of the fixed block 11 is provided with a first mounting groove 111, an adjusting block 13 is installed in the first mounting groove, the top end of the adjusting block 13 is provided with a second mounting groove 131, a pressing block 14 is installed in the second mounting groove 131, a first through groove is formed through the first mounting groove 111 to the bottom surface of the fixed block 11, a second through groove is formed through the second mounting groove 131 to the bottom surface of the adjusting block 13, the first through groove is aligned with the second through groove, a thimble 12 is installed through the first through groove and the second through groove, the lower end of the thimble 12 leaks out of the bottom surface of the fixed block 11, and the upper end of the thimble 12 is in contact with the pressing block 14.

In this embodiment, to improve the applicability of the jig, so as to process leather watchbands with different widths; it will be appreciated that the ejector pin 12 is subjected to a reverse force during ejection of the plastic part, so that if the ejector pin 12 is too long, the ejector pin 12 is easy to bend and damage or the processed product is bad, and if the ejector pin 12 is too short, the ejector pin 12 cannot penetrate the first perforation and cannot completely eject the plastic part in the leather watchband; in this embodiment, the adjusting block 13 is provided to solve such problems, and it is conceivable that the thickness from the second mounting groove 131 to the bottom surface of the adjusting block 13 is adjusted, that is, the depth of the second through groove, and the length of the ejector pin 12 leaking out of the fixing block 11 can be adjusted, so that when machining leather watchbands with different widths, only the proper adjusting block 13 needs to be replaced, the cost is saved relative to replacing the whole fixing block 11, and the adjusting block 13 is better machined relative to replacing the ejector pin 12.

In some embodiments, the lower die 2 is provided with a mounting hole 23, a guide post 24 is installed in the mounting hole 23, a through hole 112 is provided at a position of the fixed block 11 corresponding to the mounting hole 23, and the guide post 24 passes through the through hole 112 and is slidably connected with the fixed block 11.
