Specifically, the material plate 100 is stamped onto the blanking pad insert 30 by the blanking die to blank out a sheet for forming the fixing frame 10. The sheet is then stamped onto the bending pad insert by the bending die to form the fixing frame 10. Finally, the fixing frame 10 is stamped onto the cutting pad insert 80 by the cutting die to separate it from the material plate 100, forming an independent product.

[0034] Please refer to Figure 2 , Figure 6-7As shown, the punching module includes two first punches, two second punches, and two third punches. The punching pad insert 30 includes two first pad grooves 301, two second pad grooves 302, and two third pad grooves 303.

The two-stage pressing makes the dimensional accuracy of the fixing part 101 higher.

[0036] Furthermore, the blanking module also includes a punching cutter, and the corresponding blanking pad insert 30 also includes a punching pad groove. Specifically, when the material plate 100 is conveyed from the outside into the continuous stamping die, it is punched in the punching pad groove by the punching cutter, forming a fixing hole 105 in the middle of the material plate 100, which is the fixing hole 105 of the fixing frame 10.
