The reason why the world we live in is so orderly is because objects of all sizes are closely connected. So many things in life are important, no matter big or small, they are indispensable in our lives. Some small parts in life are unknown, but they are thousands, and the spring leaf I know is one of them. one.
The spring leaf always exists in the invisible position of people, silently doing its part. And, it’s everywhere in life, even if we don’t know it. Below, a brief introduction to the functions of these small spring pieces!
Spring sheets play a large or small role in our daily lives, and have different shapes and structures due to different uses. However, according to appearance, people still think that they can be divided into two categories: straight springs and curved springs. According to the shape of the spring leaf motherboard, it can also be divided into spring leaf rectangle, trapezoid, triangle, and stage shape. Its working principle is to take advantage of one of its characteristics, which is that it is easy to bend in one direction (a plane with less stiffness), while the other direction has relatively large pulling and bending forces. The spring leaf can store energy, and also has the functions of shock absorption, tightening, and measurement, as well as compression, stretching, and torsion.
Production of spring leaf
1. Material selection. Material selection is an important part of making spring sheets. Spring leaf materials are generally required to have high elasticity, impact toughness and good heat treatment properties. Therefore, commonly used spring materials include carbon spring steel, alloy spring steel, stainless steel spring, copper alloy, etc.
2. Production. Spring can be cold rolled or hot rolled. Generally, the diameter of cold-rolled shrapnel wire is less than 8mm, and the diameter of hot-rolled shrapnel wire is larger than 8mm. After selecting the manufacturing method according to the nature of the material, the shrapnel should be made into different types according to different environments and functions.
3. Due to different materials, some spring pieces need to be suppressed or shot blasted after cold rolling or hot rolling in order to fully exert the effect of the spring piece.
