[0031] During installation, the upper mold 4 is fixed on the upper table 1 of the press, and the lower mold 6 is fixed on the lower table 2 of the press. The model of the press is JK36-400F / 6.

[0032] During operation, the press drives the upper mold 4 to rise and places the accessories on the top of the forming side plate 23. After adjusting the position, the press drives the upper mold 4 to descend. When it descends to a certain position, the guide rail 9 and the guide groove 11 first contact and cooperate to guide and position. Then, as the upper mold 4 continues to descend, the convex stamping insert 13 will press the accessories to deform and enter the concave stamping insert 22. The convex stamping insert 13 and the concave stamping insert 22 cooperate to complete the stamping and forming of the accessories. Then the press drives the upper mold 4 to rise and the formed accessories can be removed. When the convex stamping insert 13 and the concave stamping insert 22 are damaged, they can be removed and replaced separately to save costs. When the guide rail 9 and the guide groove 11 are severely worn and affect the accuracy, the lower guide rail copper block 10 can be removed separately for replacement.
