[0003] For example, the patent with patent number CN216632288U discloses a pre-formed drawing die structure. During the die stamping process, the force transmitted from the hydraulic press to the pressure push rod causes the lower pressing plate to press the material first, and then the lower surface presses downward relative to the lower drawing punch to move upward to draw the flat blank upward to the concave drawing die plate for drawing. During the drawing process, when the lower drawing punch and the pre-forming punch are closed, the pre-forming punch uses multiple nitrogen springs to support the product to form a pre-formed product. At this time, the die is not closed and continues to move downward. When the die is closed, the lower drawing punch continues to move upward to close the pre-forming punch. At this time, the die forms a product stamping and completes the smooth production of the product. Compared with one-time stretching, product production can be achieved more effectively and stably. This innovative structure can effectively improve product cracking, so that such products can be smoothly produced.
