The pressure spring is a mechanical part that works by using the elasticity generated by compression. Parts made of elastic materials are compressed and deformed under the action of external force, and then return to their original state after the external force is removed. The production process of general pressure springs is: raw material procurement-raw material inspection-first sample inspection-batch winding of springs-stress relieving tempering-end grinding-setting tempering-batch inspection-surface treatment-packaging-shipment and delivery. Below, Tuba Rabbit Xiaobian introduces the specifications of pressure springs to you.

The pressure spring follows Hooke's law-its unit reduction X, under constant coefficient K (elastic coefficient), is related to the pressure F? In direct proportion, that is, f =-k x or △ f =-k δ x.

the specifications of the pressure spring mainly refer to the material, outer diameter, inner diameter, wire diameter, free length, end style, total turns, effective turns, lead and surface treatment of the pressure spring.

First of all, the material of the pressure spring is usually carbon steel, general alloy steel, piano steel wire, stainless steel wire, high-temperature alloy and other metal materials, and some of them use special materials such as plastic, which will affect the elastic coefficient K.

Secondly, the relationship among the external diameter, internal diameter and wire diameter of the pressure spring is that the external diameter of the pressure spring = internal diameter of the pressure spring+wire diameter of the pressure spring ×2, which will also affect the elastic coefficient k and the installation size of the pressure spring.

Then, the relationship between the free length of the pressure spring, the lead of the pressure spring and the effective number of turns of the pressure spring is that the free length of the pressure spring = the lead of the compression spring × the effective number of turns of the pressure spring, which will affect the installation size and compressible stroke of the pressure spring.

after that, the end style of the pressure spring, the two end rings of the pressure spring should be tight with the adjacent rings (no gap), which only plays a supporting role and does not participate in deformation, so it is called dead ring. The structure of the end of this pressure spring has many forms. The most commonly used ones are that two end rings are both tight and smooth with adjacent rings, and the two ends of the spring wire are forged flat and tight with adjacent rings during heating and winding (the end rings may or may not be smooth)? Three kinds. The total number of turns of the pressure spring = the effective number of turns of the pressure spring+the number of turns of the two end faces and the adjacent turns.

Finally, regarding the surface treatment of the pressure spring, if the spring is made of stainless steel, copper wire, plastic and other materials that are not easy to be corroded, the surface does not need to be treated. If the steel that is easy to be corroded is chosen, a metal protective layer is generally plated to prevent rust, and some of them have the effect of increasing wear resistance, such as zinc plating and chromium plating. The specifications of the pressure spring include the above. I hope these explanations of Tuba Rabbit Xiaobian can help you better understand the pressure spring.
