In almost all stamping dies, a large number of elastic components and springs are used. Among these elastic components, there are various elastic standard parts, high-strength rubber, nitrogen springs, etc. Different elastic components are selected according to different needs. For example, for bending and punching, it is enough to use common rectangular elastic components. For example: according to the color, the brown spring can also be called a coffee-colored spring; if the elastic force is not good, add a nitrogen spring instead. However, nitrogen springs are more expensive, so the mold cost is a little higher; among them, there is another elastic component called high-strength rubber. This elastic component is very cheap, but the service life of the spring is relatively short. This is generally used for drawing dies, shaping dies, or flatness adjustment.

　　The effect of using PU glue for drawing dies is quite good, of course, nitrogen springs can also be used. Others such as ejector pins, floats, dual-purpose pins, etc. generally use wire springs or yellow springs, etc., as long as they can remove the material and do not eject the product with marks or deformation. The characteristic of PU glue is that the elasticity is relatively balanced, but because of its short service life, it may crack after a period of time. Therefore, it is generally used less, and PU glue is used more for flatness.

　　Rectangular springs are generally divided into brown, green, red, blue, and yellow according to their colors. Their elastic force also weakens accordingly. Depending on the color, the elastic force is different, and the compression amount is also different.

　　The shorter the compression, the shorter the mold life (of course, the spring can be replaced if it is broken). The spring may break after a period of time, or it may simply lose its strength. A spring of poor quality can easily break in the mold. Generally, the compression of the spring is calculated based on 300,000 times, which means that the spring may lose its strength after the mold is pressed 300,000 times. Of course, the service life of general stamping molds is not that long, and it can also be calculated based on the maximum compression. If it is calculated based on the maximum compression, it can only ensure that the spring does not explode in the mold. A tighter compression of the mold is also good for the flatness of the product.

　　The maximum compression (how much this spring can be compressed), the maximum compression of the spring is equal to the original height of the spring x the maximum compression ratio of the spring. For example, the brown spring has a length of 60mm, so its maximum compression is: 60*24%, which is approximately equal to 14. This spring can be compressed to a maximum of 14 millimeters, and its maximum stroke is 14 millimeters. The stroke of the mold must be less than 14 millimeters. If it exceeds 14 millimeters, the spring may fail, deform, or break in the mold, or the mold may explode, and the punch press may not be able to press down, etc.
