DETAILED DESCRIPTION

[0015] The utility model is further described below with reference to the accompanying drawings.

[0016] like Figure 1-Figure 2 As shown, one side of the lower end of the upper die base 3 is connected to the upper die nitrogen spring 12, the lower end of the upper die nitrogen spring 12 is connected to the stripper plate 5, the other side of the lower end of the upper die base 3 is connected to the upper pad 16, the lower end of the upper pad 16 is connected to the drawing die 17, the upper end of one side of the lower die base 9 is connected to the lower mold plate 7, the upper end of the other side of the lower die base 9 is connected to the lower pad 23, the upper end of the lower pad 23 is connected to the drawing punch 21, a blank holder ring 20 is provided on the outer side of the drawing die 17, and an elastic supporting structure is provided below the blank holder ring 20, a lower die trimming edge 13 is fixed on the upper side of one side of the lower mold plate 7, and a trimming punch 18 is fixed on one side of the drawing die 17 to cooperate with the lower die trimming edge 13 for trimming.

[0017] The lower end of the lower die seat 9 is connected to the lower pad 10, the lower end of the lower pad 10 is connected to the lower support plate 11, the lower end of the pressure ring 20 is connected to the push rod 22, the lower end of the push rod 22 is connected to the lower die nitrogen spring 24, and the lower die nitrogen spring 24 is installed on the lower support plate 11.

[0018] A ejector pin 14 is installed at the inner concave part of the drawing die 17 , and a spring 15 is provided above the ejector pin 14 .

[0019] The outer side of the blank holder 20 is connected with an outer positioning block 19 .

[0020] A sleeve 4 of equal height is connected between the upper die seat 3 and the stripper plate 5 .

[0021] A square key 8 is connected between the lower mold plate 7 and the lower mold base 9 and between the upper pad 16 and the upper mold base 3 .

[0022] An upper pad 2 is connected to the upper die seat 3, and an upper support plate 1 is connected to the upper pad.

[0023] When the utility model is used, the material 6 is first conveyed to the outer positioning block 19 along the lower template 7 in the mold opening state, and then the upper support plate 1 begins to descend, the stripper plate 5 presses one side of the material 6 downward onto the lower template 7, the equal height sleeve 5 keeps the stripper plate 5 horizontal, and the upper mold nitrogen spring 12 contracts to generate a pressing force. Then the upper support plate continues to descend, the trimming punch 18 cooperates with the trimming blade 13 of the lower mold to cut the material 6, the drawing die 17 presses the cut material 6 onto the blank holder 20, and then continues to press down to make the drawing die 17 cooperate with the drawing punch 21 to press and complete the drawing.

[0024] When pressing down, the drawing punch 21 makes the material 6 bulge and embed into the inner concave part of the drawing die 17, and the ejector pin 17 shrinks. When demolding, the spring 24 ejects the ejector pin 17, so that the stamped product is demolded from the drawing die 17. The magnitude of the drawing force can be adjusted by adjusting the lower die nitrogen spring 24. The upper support plate 1 and the lower support plate 11 are used to connect with the punching machine.
