Common heterosexual spring action can be divided into the following types:
1. Ring spring of shaped spring. The ring spring is composed of a tension spring and a connecting spring. The thread pitch and rotation direction of the tension spring and the connecting spring are the same. Use a special tire clamp to clamp one end of the tension spring and screw in the connecting spring. Then, rotate the other end of the tension spring and sleeve it into the other end of the connecting spring. Use the rotation force to screw the connecting spring inside the tension spring and make the tension spring form a ring spring.
2. Wire spring of profiled spring. Wire springs are various kinds of springs made of wire with springs according to different uses, usually made of cold drawn spring steel wires. Since the cross-section of the wire spring is usually circular, its load is not limited by directionality, and at the same time, it has the same bending rigidity in all directions, so this wire spring is mostly used in occasions with small load and no strict requirements on load characteristics.
3. Scroll coil spring of special-shaped spring. Scroll coil spring is also known as scroll spring. Its function and principle are similar to that of conical coil spring. It can absorb large energy under pressure. However, it is difficult to manufacture, so it is only used in special cases where space is limited.
4. Plate spring of profiled spring. The plate spring is generally composed of single or multiple spring steel plates, which has the characteristics of cushioning and vibration reduction. The plate spring has strong cushioning and vibration damping performance, and is mainly used in the suspension device of automobiles, tractors or railway vehicles.
5. Serpentine spring of profiled spring. Serpentine spring is also known as serpentine spring, which is named because its spring shape is tortuous like a snake. According to its shape, it can be divided into "Z" shape and "s" shape spring. This kind of spring is mainly used in car cushion, so it is called seat spring.
6. Variable diameter coil spring of special-shaped spring. Variable diameter coil springs are mainly used in some special occasions. Generally, the springs are made of round cross-section materials, and most of them bear compression loads.
7. Leaf spring of special-shaped spring. Leaf springs are also known as leaf springs. The materials of the springs are mostly spring strips (or plates), and the processes are processed on special equipment or general pressure processing machine tools using corresponding molds. Because the material thickness of leaf spring, wave spring and light spring is relatively thin, they are widely used in industry.
8. Rectangular spring of shaped spring. Rectangular spring is referred to as rectangular spring for short. When the installation space is limited, the spring with rectangular section material is often used. Because the rectangular spring can obtain a large bearing load under the same space and deformation amount. Compared with the spring of circular cross-section material, the rectangular spring has a large cross-sectional area under the same space conditions, so it can absorb more energy. It is mainly used for heavy machinery, stamping dies or springs with particularly large rigidity.
9. Dished spring of profiled spring. Because of its small size and light weight, dish springs are widely used in cushioning, vibration isolation and other occasions. At the same time, they are also widely used in stamping dies, valve clutch fasteners and large construction machinery.
10. The convex spiral compression spring is one of the special-shaped springs. Since both ends of this type of spring have small coils and can be embedded in the middle coil, a large deformation amount can be obtained. For example, the middle convex automobile brake spring is always in a tight state. When the automobile valve is opened, the spring will recover its deformation and drive the brake to brake the automobile. Another example is the hairdresser's hairdresser, whose principle is the same as this, which can obtain a large amount of deformation in an effective space.
11. Unequal pitch coil spring of special-shaped spring. Unequal pitch coil springs can meet the requirements of small spring deformation and large spring deformation at the same time, because these springs are mainly used in suspension springs of motorcycles and minibuses and valve springs of high-speed engines.
12. Torsion bar spring of special-shaped spring. The essence of torsion bar spring is 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.
