Compression springs

Compression spring, also known as helical compression spring, is a very common elastic element in the engineering field, mainly used to withstand axial pressure and provide restoring force.

features of compression springs

  • Structure: Compression springs are usually spiral-shaped, and their cross-section is mostly circular, but they may also be rectangular, square or made of multiple strands of steel wire. They have various shapes, including cylindrical, conical, convex, concave, etc.
  • Deformation ability: It has strong elastic deformation ability. When compressed by external force, the spring will shrink and deform, and restore its original length after the external force is removed, thereby storing and releasing energy.
  • Gap: A certain gap is retained between the spring coils to ensure smooth deformation during compression without mutual interference.
  • Material and surface treatment: Commonly used materials include high carbon steel, stainless steel, etc., which are precision machined and surface treated to improve corrosion resistance and fatigue resistance.
  • Pitch: The spring pitch is usually equal pitch, that is, the distance between adjacent coils is equal, but there is also a variable pitch design to meet specific functional requirements.

Load support and adjustment

It can provide stable support force and is suitable for different load ranges. By adjusting parameters such as material, diameter, number of turns, etc., the load can be precisely adjusted.

Durability and reliability

Due to its material selection and processing technology, compression springs have high durability, fatigue resistance and long-term working stability.

Easy installation

The installation process is simple and quick, and usually only requires placing the spring in the predetermined position or hole.

Low maintenance cost

Maintenance and maintenance are relatively easy, reducing downtime and repair costs.

02

Design and calculation

According to customer needs, use professional spring design software or formulas (such as Hooke’s law) to calculate and determine the key parameters of the spring, such as material, wire diameter, number of turns, free length, and end treatment method.

03

Prototype production

According to the design drawings, select suitable materials (such as carbon steel, stainless steel, piano wire, etc.) and make spring prototypes through cold forming or hot forming processes. This stage may require the use of spring machines, CNC lathes, wire cutting machines and other equipment.

04

Test verification

Perform functional and performance tests on the produced spring prototype, including but not limited to load testing, fatigue testing, dimensional inspection, etc., to ensure that it meets the design requirements and relevant standards. If the test results do not meet the standards, it is necessary to return to the design stage for adjustment.

05

Mass production

After the design is confirmed to be correct, it enters the mass production stage. At this time, it is necessary to strictly control the quality of the production process, to ensure that each spring meets the quality standards.
