Abstract
The utility model discloses a high-speed punching precision terminal mechanism preventing collapsing corners after blanking. The mechanism comprises an upper male die and a lower female die. A pre-punching puncher pin and a fine-punching puncher pin of a punching terminal are sequentially arranged on the upper male die. An extrusion puncher pin and a fine-cutting puncher pin for conveniently enabling the terminal to be stamped into the terminal without the collapsing corners are further sequentially arranged between the pre-punching puncher pin and the fine-punching puncher pin. A pre-punching cutter edge and a fine-punching cutter edge are sequentially arranged on the lower female die, wherein the pre-punching cutter edge is matched with the pre-punching puncher pin, and the fine-punching cutter edge is matched with the fine-punching puncher pin. An extrusion groove and a fine-cutting groove which is matched with the extrusion groove in shape are sequentially formed between the pre-punching cutter edge and the fine-punching cutter edge. Due to the fact that the high-speed punching precision terminal mechanism comprises the extrusion puncher pin and the fine-cutting puncher pin, the shaping for the shape of a secondary terminal is carried out on the terminal through the extrusion groove, fine cutting is carried out on the collapsing corners existing in the terminal through the fine-cutting groove, finally, the collapsing corners do not exist on the surface of the terminal stamped by the fine-punching puncher pin, and the influences, caused by the collapsing corners during the one-time forming punching in the prior art, on the flatness and the percent of pass are effectively avoided.

The specific embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-2, the high speed stamping precise terminal mechanism at the angle of collapsing after the prevention stamping-out that the utility model provides, comprise upper male mould (not shown) and lower cavity die 10; Be provided with successively pre-stamping punch 11 and the smart stamping punch 14 of stamped terminals on upper male mould, between pre-stamping punch 11 and smart stamping punch 14, also be provided with successively and be convenient to terminal is struck out without extruding drift 12 and the essence of the angle terminal that collapses and cuts drift 13; On lower cavity die 10, be provided with successively with the pre-stamping knife mouth 18 of pre-stamping punch 11 adaptations, with the smart stamping knife mouth 19 of smart stamping punch 14 adaptations, be provided with successively extruding groove 15 and cut groove 16 with the essence of pushing groove 15 shape adaptations between pre-stamping knife mouth 18 and smart stamping knife mouth 19.
Situation compared to prior art, collapse after the prevention stamping-out that the utility model the provides high speed stamping precise terminal mechanism at angle, this mechanism comprises that extruding drift 12 and essence cut drift 13, carry out the typing of secondary terminals shape by 15 pairs of terminals of extruding groove, cutting groove 16 by essence carries out essence by the angle of collapsing existed in terminal and cuts, make the angle of not collapsing, its surface of terminal finally stamped out by smart stamping punch 14, effectively avoided the impact of angle on terminal flatness and qualification rate of collapsing that in the prior art, the one-shot forming punching press causes.This improved mechanism is pre-anti-collapse angle, the flatness of greatly having improved the terminal outward appearance and the stability of quality effectively, can better meet client's requirement high-quality to terminal.
