technical field

The invention relates to a stamping die capable of finely adjusting a die punch, and belongs to the technical field of stamping dies.

Background technique

Stamping die is a special process equipment for processing materials (metal or non-metal) into parts in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. For products with complex shapes, it is often necessary to perform lateral stamping on a certain part or parts of the product to form a lateral core-pulling; and the mechanism for completing the lateral stamping process mainly relies on the drive block to drive the insert to move laterally. To achieve, in the shrapnel and terminal molds, due to the instability of the angle springback, it is often necessary to reshape, especially for products with strict angle requirements.

During plastic surgery, the conventional method is to use a punch to fix it, and the plastic surface is a flat plastic method. In this kind of shaping method, due to the influence of factors such as material thickness deviation, mold manufacturing error and forming process, it is easy to cause the punch and the insert to be stuck. At this time, it is necessary to disassemble the template and repair the punch. If the adjustment is not good, the mold must be demolished many times, and the mold adjustment time will increase several times. During production, due to the deviation of the hardness and thickness of the material, the angle is out of tolerance, and the mold must be demolished and adjusted, which greatly increases the workload. , resulting in delays in production schedules. For this reason, it is necessary to design a new technical solution that can comprehensively overcome the deficiencies in the above-mentioned prior art.
