Roll forming machine 6 Ways to improve stampings life!（一）

    Roll forming machine stamping process is an essential process equipment, improve product quality, extend product life, improve production efficiency have a decisive role. However, since the stamping parts in the production process often lose their jobs wear size, it makes it difficult to meet production needs. Therefore, improving the durability of stamping dies (life) is critical.
Roll forming machine to improve the durability of the stamping method generally have the following:

1. An improved roll forming machine stamping parts of the design

    Whether to study a press roll forming machine part is designed to improve the durability of the foundation stamping. Therefore, when dealing with product design stamping molding adverse conditions and take effective measures to improve the durability of stampings, such as life design stamping holes often manifested in the red hole punch. For this type of stampings, it should be designed so that small punch to shorten its length to increase the strength, should also adopt the method of strengthening the guide sleeve to protect small punch. In addition, the stamping design, should be fully taken into account in the form of fixation methods and guide in the form of mold, punch, and determining and upper and lower rigid template center of pressure and other factors. Especially for stamping die, the selected clearance value has a great influence on durability. At design time, the gap should be a reasonable choice stampings, the gap value can not be too small, otherwise it will affect the life and durability of stamped parts. Practice has proved that, without affecting the quality of stamping the case, appropriate to enlarge the gap can greatly improve the durability of the stamping dies, sometimes even several times and several times increase.
