1 Design and Manufacturing Requirements

Automotive stamping dies have high application frequency, usually around 700,000 uses, and up to 800,000 uses for high-quality dies. Die design is critical to improving die quality. It not only needs to consider the process structure but also control and manage machining, installation, debugging and transportation processes to ensure the die has high guidance and structural integrity. In addition, the safety and maintainability of the die must be fully considered to improve design quality.

2 Die Material Selection

Before stamping die design, production conditions and output must be fully considered to ensure the die material's strength, hardness and other properties meet service life requirements, and then a suitable die material should be selected. After determining the material of each die component, tensile tests, hardness tests and material composition analysis are required. The die material must be clearly defined during design and proofreading, and performance comparison should be conducted during pre-acceptance. For high-requirement dies such as drawing dies, ultrasonic testing of the surface is required during acceptance to check for micro-cracks, ensuring the material meets quality requirements and the produced parts can achieve mass production and high punching times.

3 Design of punching components

In punching die design, guide pillars must be used together with guide plates to ensure uniform clearance between the punch and die, as well as the dimensional accuracy of punched parts. For punched parts, in addition to ensuring part accuracy, special attention should be paid to punching waste discharge. Excessively deep die blanking hole wall thickness easily causes waste accumulation; excessively thin thickness reduces part strength and even leads to die cracking, significantly shortening die service life. Therefore, graded punching must be adopted in design and processing, and fixed by a fixing plate to stabilize the die's punching structure. Proper die positioning can effectively improve the dimensional accuracy of parts during punching and blanking.
