1. Reducing helical springs for special-shaped springs. Reducing diameter spiral springs are mainly used in some special occasions. The springs are generally circular cross-section materials, and most of them bear compressive loads.
2. Springs of special springs. Sheet springs are also called sheet springs, and springs are made of spring strips (or plates). The process is based on special equipment or general-purpose pressure processing machines that use corresponding molds. Since the material thickness of the leaf spring, the wave spring, and the light spring is thin, such a spring is widely used in the industry.
3, rectangular spring shaped spring. Rectangular springs are abbreviated as rectangular springs. They are springs that use rectangular cross-section materials when the installation space is limited. Because this rectangular spring can obtain a larger load bearing capacity in the same space and deformation. Compared to a spring with a circular cross-section material, a rectangular spring has a large cross-sectional area of the rectangular spring under the same space condition, and therefore can absorb a large amount of energy, and is often used for a heavy machine, a punching die, or a particularly rigid spring.
4, shaped spring disc spring. Because of its small size and light weight, the disc spring is widely used in applications such as cushioning, vibration isolation, and the like. It is also widely used in stamping dies, valve clutches, and large construction machinery.
5. Convex spiral compression spring
Since these springs have smaller coils at both ends and can be embedded in the middle coils, a larger amount of deformation can be obtained. For example, in a convex automobile brake spring, this spring is always in a tight state. When the automobile valve is opened, the spring will be deformed and the brake will be activated to brake the automobile. Another example is the haircut that hairdressers use in their haircuts. The principle is the same as this, and they are all able to obtain a large amount of deformation in an effective space.
6. Scroll coil spring
Spiral coil spring is also called scroll spring. Its function and principle are similar to that of the conical coil spring. It can absorb the pressure and can generate large energy. However, it is difficult to manufacture because it is used in special circumstances when space is limited. 7. Special-shaped spring plate springs. Plate springs are generally formed by the superposition of single or multi-piece spring steel plates and have the characteristics of cushioning and vibration reduction. The plate springs have strong cushioning and vibration damping properties, and are used in the suspension devices of automobiles, tractors or railway vehicles on a daily basis.
8, ranging from the coil spring
Unequal pitch coil springs can satisfy both the small stiffness when the amount of deformation of the spring is small and the high stiffness requirement when the amount of deformation is large. Such springs are mainly used in the suspension springs and high speeds of motorcycles and small passenger cars. Engine valve springs.
9, torsion bar spring. The essence of the torsion bar spring is to use a straight bar made of elastic material under the action of torque. Because this spring has the characteristics of large deformation energy per unit volume, it is mainly used in the suspension devices of various vehicles in daily life.
10. Ring springs. An annular spring, also called a ring spring, is formed by an outer ring with an inner tapered surface and an inner ring with an outer tapered surface. Among them, the number of pairs of the inner and outer rings of the ring spring is determined according to the magnitude of the load and the requirement of deformation. Due to the high damping performance of this type of ring spring, it is mainly used in springs in heavy equipment and buffer devices.
11. Line springs. Wire springs are various types of springs that are manufactured according to different uses by springs with wires, usually made of cold-drawn spring steel wires. Because the cross section of the wire spring is often round, its load has no directionality, and it has the same flexural rigidity in all directions. Therefore, the wire spring is used for small loads and has no strict requirements on the load characteristics. occasion
12. The serpentine spring of special spring. The serpentine spring, also known as the serpentine spring, is mainly named because its shape is meandering like a snake. According to its shape, it can be divided into "Z" shape and "S" shape spring. This type of spring is widely used in automotive seat cushions and is called a seat spring.
