Abstract

The invention discloses a trimming and punching die which comprises an upper die base and a material pressing core. The trimming and punching die further comprises a driving block, a sliding block, a guide sleeve, a punching male die and an elastic piece. The driving block is fixed on the upper die base, the guide sleeve and the elastic piece are arranged on the material pressing core, and the punching male die is fixedly arranged at the lower end of the sliding block. The sliding block and the guide sleeve are in sliding connection, the sliding block is driven by the driving block which is arranged above the sliding block, and the lower end of the sliding block is in lap joint to the elastic piece. According to the trimming and punching die, the size of the sliding block can be correspondingly decreased compared with the prior art, and thus the series of problems that the overall size of a die is large, and the power needed for driving and restoring the sliding block is large in the prior art are solved at the same time.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a trimming and punching die. Background technique [0002] In fields such as automobile manufacturing, it is often necessary to perform flanging, punching and trimming operations on large-area panels. figure 1 It is a partial schematic diagram of a trimming punching die in the prior art; as figure 1 As shown, the trimming punching die includes a punching punch 12, a slide block 11 and a lower drive block 13, one end of the slide block 11 is fixed to the punch punch 12, and the other end of the slide block 11 is slidably connected with the lower drive block 13 through a wedge structure. , the lower driving block 13 is fixed on the lower mold base (not shown in the figure) of the trimming punching die. In the middle, the slide block 11 is forced to move down and thereby drives the punching punch 12, and the punching punch 12 is pressed against the plate to complete the punching ...
