6 ways to improve the durability of stamping dies

Stamping dies are indispensable process equipment in the stamping process. As a precision stamping manufacturer, it is very important to improve the durability of stamping dies, not only can improve production efficiency, improve product quality, but also save production costs. . Here we will introduce 6 ways to improve the durability of stamping dies. 1. Improving the design of stamping dies Whether the design of stamping dies is reasonable is the basis for improving the durability of stamping dies. Therefore, when designing the stamping die, effective measures should be taken to improve the durability of the stamping die. In addition, in the design of the stamping die, full consideration should be given to factors such as the form of the die base, the fixing method and guiding form of the male and female dies, the determination of the pressure center/center, and the rigidity of the upper and lower templates. Especially for the blanking die, the selection of the gap value has a great influence on the durability. 2. Correct selection of stamping die materials. Different stamping die materials have different strength, toughness and wear resistance. Under certain conditions, the use of excellent* materials can increase the durability several times. Therefore, in order to improve the durability of the stamping die, it is necessary to select good materials. 3. Reasonable forging and heat treatment of stamping die parts. While selecting good stamping die materials, reasonable forging and heat treatment are required for materials of the same material and different properties, which is one of the main ways to improve the durability of stamping dies. 4. Reasonably arrange the stamping die manufacturing process and ensure the processing accuracy. The stamping die processing accuracy has a great influence on the durability of the stamping die. For example, due to the uneven assembly gap in the punching die, the die will often be broken under the action of shearing force and affect the life of the punching die. At the same time, the surface finish of the stamping die is too low, which will also reduce the durability of the stamping die. Therefore, it is necessary to pay sufficient attention to the size of the hole spacing, the perpendicularity of the punch to the fixed plate support surface during assembly, the uniformity of the spacing between the stamping dies, and the guiding accuracy level of the guide sleeve and the guide post. 5. Choose the correct press. In order to improve the durability of the stamping die, a press with higher precision and higher rigidity should be selected, and the stamping tonnage should be more than 30% greater than the punching force. 6. Reasonable use and maintenance of stamping dies In order to improve the durability of stamping dies, operators need to use and maintain stamping dies reasonably, and the stamping dies should be repaired frequently to prevent the stamping dies from working with defects.
