6 ways to improve the durability of stamping dies.

2022-10-12

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, which can not only improve production efficiency, improve product quality, but also save production costs. . Below we will introduce 6 ways to improve the durability of stamping dies.


1. Improve the design of stamping die

Whether the design of the stamping die is reasonable is the basis for improving the durability of the stamping die. Therefore, when designing stamping dies, effective measures should be taken against unfavorable conditions in product forming to improve the durability of stamping dies. In addition, in the design of stamping die, factors such as the form of the mold base, the fixing method and guiding form of the convex and concave die, the determination of the pressure center/center and the rigidity of the upper and lower mold plates should be fully considered. 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 high-quality 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. Reasonably carry out 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 die.


4. Reasonably arrange the stamping die manufacturing process and ensure the machining accuracy

The machining accuracy of the stamping die 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 damaged under the action of shearing force, which will 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, during processing, it is necessary to pay full attention to the size of the hole spacing, the verticality of the support surface of the punch to the fixed plate during assembly, the uniformity of the spacing between the stamping dies, and the guide accuracy level of the guide sleeve and guide post.


5. Correct selection of presses

In order to improve the durability of the stamping die, a press with higher precision and higher rigidity should be selected, and its stamping tonnage should be more than 30% greater than the stamping force.


6. Reasonable use and maintenance of stamping dies

In order to improve the durability of the stamping die, the operator needs to use and maintain the stamping die reasonably, and the stamping die should be frequently repaired to prevent the stamping die from working with diseases.
