Description

Technical Field

[0001] This utility model relates to the field of stamping, and in particular to a cantilever stamping quick support device. Background Technology

[0002] For cylindrical workpieces, traditional punching methods include: 1. The die is inserted directly into the product without support at the bottom, leaving the bottom suspended. The disadvantages of this method are: the die is easily damaged, and the product's positioning stability during stamping is poor, making it difficult to guarantee punching accuracy and overall product dimensional consistency. 2. The product is placed vertically, and a wedge structure is used for punching. The disadvantages of this method are: complex die structure, high manufacturing cost, and the impact force from punching on one side during stamping can easily cause the die to gradually deform or wear, resulting in a significant decrease in accuracy after long-term use and high subsequent maintenance costs.
