holger heuer Fastener springs are a widely used category 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 a small number of non-circular forms. There is a certain gap between the coils of compression springs; when subjected to external loads, the springs compress and deform, storing strain energy. Variable-pitch springs are becoming increasingly common, rather than only constant-pitch springs being used. Variable-pitch springs can perform different functions under varying conditions. Although the spring industry is a small sector within the overall manufacturing industry, its role is absolutely significant. To accelerate the development of the national industrial manufacturing and automotive industries, the spring industry, as one of the basic components and parts, requires a development phase that is ahead of schedule to adapt to the rapid growth of the nation's entire industry.

holger heuer fasteners development history

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 and conquest of the world 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. Since clockmakers' springs were often handmade, mass production of springs used materials such as 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 specialized machinery process.

holger heuer fasteners 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 cone 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, ability to be formed into various types based on 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.

holger heuer fasteners manufacturing

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, 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: increasing forming speed, with the main trend being improved 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 enable automatic closed-loop control of the CNC forming machine manufacturing process. Cold forming process capability has limitations for variable-diameter, constant-diameter, or eccentric springs. Hot forming process speed capability shows a significant gap compared to developed countries. Large spring hot forming process control capability.
