Technical Problem
[0004]本发明的目的在于提供一种拉延模具，以解决现有技术中存在的刺破刀不适用于位于制件的大斜面上的工艺口成型的问题
Benefits of technology
[0016] This invention provides a drawing die in which an insert and a punch work together to form a recess. Since more material is required for the sidewalls of the recess, the sidewalls first crack and gradually expand during the forming process to form a process opening. This prevents cracking of the drawn part at non-process opening locations. Because the process opening appears through cracking, the insert does not need to pierce the drawn part, thus eliminating the need for a sharp point or cutting edge. Consequently, the relative sliding between the insert and the drawn part does not produce waste material, preventing damage to the drawn part caused by waste material.

Abstract
The present application relates to the technical field of stamping die, and particularly discloses a drawing die, a female die is fixedly connected with an upper bottom plate, a male die is fixedly connected with a lower bottom plate, the female die can be matched with the male die to make a drawing product shaped, an insert block is fixedly connected with the female die and can be matched with the male die, the insert block is arranged on a bevel shaping part of the female die and is used for shaping a pit at a position where a process port of the drawing product is arranged, and the process port is shaped on a side wall of the pit. The insert block is matched with the male die to shape the pit, and since more material is required at the side wall of the pit, cracking of the side wall of the pit occurs first in the shaping process and gradually expands to form the process port, so as to avoid cracking of the drawing product at a position other than the process port, the process port is formed in a cracking manner, the insert block does not need to pierce the drawing product, and therefore a sharp end or a blade edge does not need to be arranged, so that relative sliding between the insert block and the drawing product will not cut off waste chips, and waste chips will not cause the drawing product to be crushed.
