Coil Spring Making Machine

1. According to the different characteristics of the load at work, the coil spring can be divided into three types: compression, tension and torsion; 2. According to the structural characteristics, it can be divided into two categories: cylindrical coil springs and variable diameter coil springs; variable diameter coil springs The spring mainly bears the compressive load; 3. According to its shape characteristics, it can be divided into conical, scroll, concave and convex. 4. In terms of production and use, coil springs can also be divided into two categories according to the forming method and the diameter of the material: large coil springs and small coil springs; the former is usually hot formed, and the latter is cold formed. 5. Other categories
There are many types of coil springs, which can be divided into: ordinary cylindrical coil springs; variable diameter coil springs.

①Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc. ② Absorb vibration and impact energy, such as buffer springs under automobiles and train carriages, vibration-absorbing springs in couplings, etc. ③ Store and output energy as power, such as clock springs, springs in firearms, etc. ④Used as a force measuring element, such as a force measuring device, a spring in a spring balance, etc. The ratio of the load to the deformation of the spring is called the spring stiffness, and the higher the stiffness, the stiffer the spring.
The spring is an elastic element widely used in the mechanical and electronic industries. The spring can produce a large elastic deformation when it is loaded, and convert the mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original state. Deformation energy is converted into mechanical work or kinetic energy.

1. Variable diameter coil springs are divided into: conical coil springs, spiral coil springs, and concave coil springs.
2. The conical coil spring has better cushioning performance and can withstand larger loads.
3. Spiral coil springs can store more energy and bear larger loads, but the manufacturing process is more complicated.
4. The performance of the concave coil spring is similar to that of the conical coil spring, and it is mostly used for cushions and mattresses.
5. The surface of the spring steel wire is round and rectangular, and the circular section is the most commonly used.
6. The coil spring is the torsion spring, which is a spring that bears torsional deformation, and its working part is also tightly wound into a spiral shape. The end structure of the torsion spring is a torsion arm machined into various shapes, rather than a shackle. Torsion springs are often used in balancing mechanisms in machinery, and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.
Features:
1. The structure is relatively compact;
2. Good softness, that is, the deformation range is relatively wide;
3. It is easier to manufacture;
4. High energy rate.
