How to improve the durability of hardware dies_

Generally, there are several ways to improve the durability of stamping dies: 1. Improve 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. For example, the life of the small hole stamping die is often reflected in the punching die for punching small holes. For this type of stamping die, the length of the small punch should be shortened as much as possible in the design to increase the strength. At the same time, the method of guiding sleeves should be used to strengthen the small punch for protection. 2. Correctly choose stamping die materials. Different stamping die materials have different strength, toughness and wear resistance. Under certain conditions, the use of advanced materials can increase durability several times. Therefore, in order to improve the durability of the stamping die, a good material must be selected. 3. Reasonable forging and heat treatment of stamping die parts. While selecting high-quality 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. For example, during quenching, if overheating is produced during heating, not only will the work piece become too brittle, but it will also easily cause deformation and cracking during cooling, which will reduce the durability. Therefore, when manufacturing stamping dies, the heat treatment process must be reasonably mastered. 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, during processing, full attention must be paid to the size of the hole spacing, the perpendicularity of the punch to the fixed plate supporting surface during assembly, the uniform spacing of the stamping die, and the guiding accuracy level of the guide sleeve and the guide post. The higher the manufacturing and assembly accuracy and the higher the surface roughness of the working part, the higher the durability of the stamping die. 5. Correct selection of the 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. Normally, the use of a servo punch can increase the life of the mold by several to several tens of times. 6. Reasonable use and maintenance of stamping dies In order to improve the durability of stamping dies, operators must use and maintain stamping dies rationally. Stamping dies should be repaired frequently to prevent stamping dies from working with defects. The above are the commonly used methods to improve the wear resistance of stamping dies. The significance of improving the wear resistance can not only increase the service life of stamping dies, reduce the production cost of mold companies, but also ensure the quality of products produced and improve production. effectiveness.
