zimmermann technische fastener springs are a category of mechanical parts used for fastening connections and are extremely widely applied. They are helical springs that bear axial compressive loads, Springs are generally classified into constant-pitch springs and variable-pitch springs, The shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes, etc., There is a certain gap between the coils of compression springs, When subjected to external loads, the spring contracts and deforms, storing deformation energy. Variable-pitch springs are becoming increasingly common, no longer limited to just constant-pitch springs, Variable-pitch springs can perform different functions in different environments. Although the spring industry is a small sector within the entire manufacturing industry, the role it plays cannot be overlooked. To accelerate the development of the national industrial manufacturing and automotive industries, the spring industry, as one of the basic components and parts, requires even more advanced development, in order to adapt to the rapid development of the nation's entire industry.

zimmermann technische 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, during the Renaissance, precise clocks made precision springs a necessity for the first time. 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 provide impetus for the clockmakers' science and art. Another field, firearms, drove spring development. As the Industrial Revolution approached in the eighteenth century, there was a demand for large, accurate, and inexpensive springs. Since 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 specialized machinery process.

zimmermann technische fasteners structure

Springs are a type of mechanical component used for fastening connections and are widely applied. According to the nature of the force, 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, 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.

zimmermann technische 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 processing, note that support coils can be closed using either cold or hot methods according to product requirements. Cold forming processes require one-time automation. Development directions for forming equipment include: 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 implement automatic closed-loop control of the manufacturing process for CNC forming machines. Capabilities of cold forming processes. Cold forming processes for variable-diameter or equal-diameter and eccentric springs still have limitations. Capabilities of hot forming processes. There is a significant gap compared to developed countries. Control capabilities for large spring hot forming processes.
