Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a left shaping punch 6 and a right shaping punch 10 are respectively connected and arranged on the left side and the right side of the center of the bottom of the upper die holder 1, the inner side of the right shaping punch 10 is connected with one end of a nitrogen spring 9 through a bolt, and the other end of the nitrogen spring 9 abuts against the inner wall of the left shaping punch 6; the central connection that is located the die holder 3 top is equipped with into piece 13, and the left and right sides of shaping piece 13 is equipped with left side respectively and leans on piece 2 and right side to lean on piece 11 to left side leans on piece 2 and right side to lean on piece 11 to be located the front side and the rear side position of left side plastic drift 6 and right side plastic drift 10.
And a self-lubricating sliding plate 7 is arranged between the bottoms of the left shaping punch 6 and the right shaping punch 10 and the upper die base 1.
A guide block 8 is arranged between the left shaping punch 6 and the right shaping punch 10.
And the left side and the right side of the left shaping punch 6 and the right side shaping punch 10 are respectively provided with a stop block 5, and the bottom of the stop block 5 is embedded in the upper die base 1. The stopper 5 restricts a sliding space between the left and right shaping punches 6 and 10.
