[0024] As Figures 1 to 5 shown, the present application provides a design of an iron-tooth zipper excess material punching and grinding tool, which comprises a punching machine table 1, a support frame 2 is fixedly arranged at the upper end of the punching machine table 1, and a hydraulic cylinder 3 is fixedly arranged at the upper end of the support frame 2, one end of the hydraulic cylinder 3 penetrates into the inside of the support frame 2 and is connected with an upper die holder 4 at the extended end, a lower die holder 5 is fixedly arranged at the upper end surface of the punching machine table 1, a punching table 51 is fixedly arranged at the upper end of the lower die holder 5, and a positioning structure 7 is arranged at the upper end of the punching table 51.

[0025] Two disassembly structures 6 are symmetrically arranged at the lower end of the upper mold base 4. The disassembly structure 6 includes a mounting bracket 61. There are two mounting brackets 61, and the two mounting brackets 61 are fixedly installed at the bottom of the upper mold base 4. A guide slider 62 is slidably connected inside the mounting bracket 61, and a punching blade 63 is fixedly connected to the bottom of the guide slider 62. Two limit brackets 64 are symmetrically fixedly arranged on the outside of the mounting bracket 61. A pull rod 65 is slidably connected inside the limit bracket 64, and a return spring 66 is sleeved on the outer wall of the pull rod 65.

[0026] like Figures 3 to 4 As shown, the two punching blades 63 are adapted to the size of the toothed zipper. A fixing rod 67 is fixedly installed on the outer wall of the pull rod 65. One end of the return spring 66 is connected to the fixing rod 67, and the other end is in contact with the inner wall of the limit frame 64. A snap-fit ​​block 68 is fixedly installed on the inner wall of the limit frame 64. One end of the fixing rod 67 is adapted to the groove on the inner wall of the snap-fit ​​block 68.

[0027] By pulling the pull rods 65 on the limit brackets 64 on both sides of the mounting bracket 61, the pull rods 65 drive the fixed rods 67 to compress the return spring 66. Then, while pulling the pull rods 65, rotate them to 90 degrees. Then, snap one end of the fixed rod 67 onto the snap block 68. After both sets of pull rods 65 have been operated, pull the punching blade 63 and slide it out of the mounting bracket 61 using the guide slider 62 to facilitate the maintenance and replacement of the punching blade 63.

[0028] like Figure 5 As shown, the positioning structure 7 includes a placement frame 71 fixedly installed on the upper end of the stamping table 51.
