Experience sharing of precision stamping die design process

The mold industry is in deep water, and technology requires long-term accumulation and practice. Precision can design and manufacture stamping and injection molds according to the different needs of customers, and apply them to internal production, and has accumulated rich experience in mold technology. Next, the precision technicians will share with you some experience in the design of precision stamping die products. 1. The punching position of the product is too close to the bending edge, the bending hole will be deformed after punching first, and there is no strength after punching first. At this time, in order to ensure the size, it is recommended to open a process hole at the bending position to avoid the hole position. 2. The corner is similar to the convex hull. The corner position is very easy to break due to the pulling material. In order to ensure the appearance, it needs to be changed to a process hole to remove the corner position. 3. The bending position will often be bent to the inside of the material. In fact, the printed product is very ugly. In order to ensure the stable angle and appearance, it is necessary to add process grooves at the bending position. 4. The bending position is directly connected with the product plane, which is prone to cracking after bending. In order to ensure the bending angle and appearance, it needs to be improved to bend with straight sections, and the height H should not be less than 2T. 5. The bending angle is too large. In order to ensure the stability of the angle and reduce the rebound when the mold is used for one-time molding, a bulge (called: stiffener) can be added in the middle to ensure stability and force. 6. When the product material is thick, the product position is prone to cracks or even cracks after bending. In order to reduce this situation, try to keep the punching burr on the inner side of the bend. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
