polymehr fastener springs are a widely used class of mechanical components for fastening connections. They are helical springs that withstand axial compressive loads. Springs are generally classified into constant-pitch and variable-pitch types. Compression springs come in various shapes, including cylindrical, conical, convex, concave, and, less commonly, non-circular forms. There is a certain gap between the coils of a compression spring; when subjected to external loads, the spring compresses and deforms, storing strain energy. Variable-pitch springs are becoming increasingly common, rather than relying solely on constant-pitch designs, as they can perform differently under varying conditions. Although the spring industry is a small sector within the overall manufacturing industry, its role is by no means negligible. To accelerate the development of the national industrial manufacturing and automotive industries, the spring industry, as a provider of basic components and parts, requires a development lead time to keep pace with the rapid growth of the nation's entire industrial sector.

History of polymehr fasteners development

Springs are a type of mechanical component used for fastening connections and are widely applied. Like most other basic mechanisms, metal springs have existed since the Bronze Age. Even with metals, it was during the Renaissance, with precise clocks, that precision springs first became essential. The fourteenth century saw the development of revolutionary astronomical navigation and precise clocks. The exploration of the world and conquest by European colonial powers continued to drive the clockmakers' science and art. Another field, firearms, also promoted spring development. With the advent of the Industrial Revolution in the eighteenth century, there was a demand for large, accurate, and inexpensive springs. Given that clockmakers' springs were often handmade, mass-produced springs were made from music wire or similar materials. Advanced manufacturing methods have made springs ubiquitous. Computer-controlled wire and sheet metal bending machines allow for custom spring processing, which is clearly a type of specialized machinery.

polymehr fastener structure

Springs are a type of mechanical component used for fastening connections and are widely applied. According to the nature of the force applied, springs can be divided into tension springs, compression springs, torsion springs, and bending springs. By shape, they can be classified as disc springs, ring springs, leaf springs, helical springs, truncated conical volute springs, and torsion bar springs. By manufacturing process, they can be divided into cold-coiled springs and hot-coiled springs. Ordinary cylindrical springs are the most widely used due to their simple manufacturing process, ability to be made into various forms according to load conditions, and simple structure. Spring manufacturing materials should generally have high elastic limits, fatigue limits, impact toughness, and good heat treatment performance. Commonly used materials include carbon spring steel, alloy spring steel, stainless spring steel, as well as copper alloys, nickel alloys, and rubber. Spring manufacturing methods include cold coiling and hot coiling.

Due to product structure limitations, these components generally feature high strength and good performance, requiring the material to guarantee final performance in terms of spring strength and toughness. During the processing process, note that support coils can be closed using either cold or hot methods depending on product requirements. Cold forming processes require one-time automation. The development direction of forming equipment includes: improving forming speed, with the main trend being increased equipment forming speed, i.e., production efficiency; improving equipment durability by enhancing the precision of equipment parts and strengthening heat treatment effects; adding length sensors and laser rangefinders to implement automatic closed-loop control of the CNC forming machine manufacturing process. Limitations of cold forming process capabilities. Cold forming processes for variable-diameter or equal-diameter and eccentric springs still have limitations. Hot forming process speed capabilities. There is a significant gap compared to developed countries. Control capabilities for large spring hot forming processes.
