Die process structure facilitating discharging of fender wheel opening waste and using method

Abstract

The invention discloses a die process structure facilitating discharging of fender wheel opening waste and a using method. The die process structure comprises a punching female die, a punching male die, an OP30 cut-off tool, an OP30 punching and flanging insert and an OP30 waste sliding way. The punching female die is fixed on an OP20 lower die holder through a bolt, the punching male die is fixed on an OP20 upper die holder through a bolt, the OP30 cut-off tool is fixed on an OP30 lower die holder through a bolt, the OP30 punching and flanging insert is fixed on an OP30 upper die holder through a bolt, the OP30 waste sliding way is fixed to the OP30 lower die holder through the bolt, and a position of the OP30 waste sliding way is in lap joint with the back of the OP30 cut-off tool, and is used for bearing OP30 waste. By renovating an OP20 wheel opening part die process structure, under the condition that the number of original dies is not increased, a waste material separation process completed in an original process is divided into two processes to be completed, the problem that the waste is discharged upwards to cause deviation of a process part is solved with an extremely low cost, the production efficiency is improved, potential safety hazards are eliminated, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of cold stamping dies, in particular to a die process structure and a use method thereof which facilitate the discharge of fender wheel mouth waste. Background technique [0002] In the mass production process of cold stamping dies for automobile outer panels, such as figure 1 As shown, during the upward discharge process of a piece of waste material A1 in the middle of the fender mold OP20 wheel mouth, because the distance between the waste material A1 and the process part A is too close after cutting, the process part A will often be biased. At this time, the process part A The position of the OP20 punch is offset, and the automatic line manipulator cannot complete the gripping action, resulting in interruption of continuous production and seriously reducing production efficiency. Sometimes the offset of process parts is too large, which not only has potential safety hazards but also causes process parts to be scra...

Problems solved by technology

[0002] In the mass production process of cold stamping dies for automobile outer panels, such as figure 1 As shown, during the upward discharge of a piece of waste material A1 in the middle of the fender mold OP20 wheel mouth, because the distance between the waste material A1 and the process part A is too close after cutting, the process part A will often be biased. At this time, the process part A The position of the OP20 punch is offset, and the automatic line manipulator cannot complete the gripping action, resulting in interruption of continuous production and seriously reducing production efficiency

Sometimes the offset of process parts is too large, which not only has potential safety hazards but also causes process parts to be scrapped, which increases production costs

In addition, if the waste material A1 of this piece is arranged to be discharged downward, it will cause two adjacent pieces of waste material to be discharged upward, which is not worth the candle.
