[0018] The two sides of the lower end of the stripper plate 4 are connected with a pressing plate 24 , and the two sides of the inclined wedge slider 21 are embedded in the grooves above the pressing plate 24 .

[0019] Hanging plates 18 are connected to both sides of the lower end of the upper die base 1 , and a protrusion for blocking the stop plate 19 is provided below the hanging plate 18 .

[0020] The lower end of the upper die seat 1 is connected to an upper pad 2, the lower end of the upper pad 2 is connected to an upper clamping plate 3, an inner guide column 12 is installed in the upper clamping plate 3, the stripping plate 4 and the lower template 5 are provided with an inner guide sleeve 7, and the inner guide column 12 passes through the inner guide sleeve 7.

[0021] The upper end of the lower die base 1 is connected to the lower pad 6 , and the upper end of the lower pad 6 is connected to the lower template 5 and the inner limit block 25 . The inner limit block 25 is embedded in the lower template 5 , and the height of the inner limit block 25 is higher than the lower template 5 .

[0022] The reverse side of the lower die insert 13 on which the punching die 9 is fixed leans against the stripping plate 4 .
