Basic knowledge of die spring compression

[guide] the purpose of die spring is to strip and press the material. The strength of the spring is related to the smooth production of the die and the qualified products. The spring force is small, which may cause various problems such as product deformation, die not detaching, product not easy to take out from the die, strip material, knife edge, punch easy to wear, etc.

The purpose of die spring is to take off and press the material. The strength of spring is related to whether the die production is smooth and whether the products are qualified. The spring force is small, which may cause various problems such as product deformation, die not detaching, product not easy to take out from the die, strip material, knife edge, punch easy to wear, etc.

　　

According to different production times, the larger the compression amount is, the shorter the service life of the spring is, and the shorter the service life of the die is. Of course, if the spring is broken, it can be replaced. However, the specifications of each spring are different, which has been determined in the design, and the springs should not be replaced each other easily in use. The spring may be out of force after a period of die production, and the spring with poor quality may break in the die.

Generally, the compression amount of die spring is calculated according to 300000 times, that is to say, the spring may be out of force when the die is hit 300000 times. Of course, the life of general stamping die is not that long. It can also be calculated according to the maximum compression amount. If it is calculated according to the maximum compression amount, it can only ensure that the spring does not explode in the die. Die press a little bit, on product flatness is also good.
