Common special shaped spring and its function characteristics

The special-shaped spring is made on the basis of ordinary spring. The special-shaped spring is mainly used in some special occasions, its spring is generally round section material, and most of them bear compression load

1. Leaf spring: leaf spring is also known as leaf spring. The material of leaf spring is mostly spring strip (or plate). Its process is processed by corresponding mold on special equipment or general pressure processing machine. It is widely used in industry.

2. Rectangular spring: rectangular spring is called rectangular spring for short. When the installation space is limited, the rectangular section material is often used. Because the rectangular spring can obtain larger load in the same space and deformation. Compared with the spring of circular cross-section material, the rectangular spring has a larger cross-section area under the same space conditions, so it can absorb more energy. It is mostly used in heavy machinery, stamping dies or springs with particularly large stiffness.

3. Disc spring: due to its small size and light weight, disc spring is widely used in buffering, vibration avoiding and other occasions. At the same time, it is also widely used in stamping dies, valve clutch fasteners and large construction machinery.

4. Convex spiral compression spring: because the two ends of this kind of spring have smaller coils and can be embedded into the middle coil, it can obtain larger deformation. For example, the convex type of automobile brake spring, this kind of spring is always in a tight state. When the automobile valve is opened, the spring will recover and deform, driving the brake to brake the automobile. For example, the principle of the hairdresser's push is the same as this, which can get a larger deformation in the effective space.

5. Scroll coil 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 more energy under pressure, but it is difficult to manufacture, so it is only used in special cases with limited space.
