Various special-shaped springs and functional characteristics

Various special-shaped springs and functional characteristics

1. Variable diameter helical spring of special-shaped spring. Variable diameter helical springs are mainly used in some special occasions, and their springs are generally circular cross-section data, and most of them accept tightening loads.

Second, dish-shaped spring of special-shaped spring. Because of its small scale and light weight, the dish spring is widely used in cushioning, vibration avoidance and other occasions, and it is also widely used in stamping dies, valve clutch fasteners and large construction machinery.

Three, torsion bar spring of special-shaped spring. The essence of torsion bar spring is to use a straight rod made of elastic data by torque effect, because this spring has the characteristics of large deformation energy per unit volume, and is mainly used in various vehicle suspension equipment in daily life.

Four, the snake spring of special-shaped spring. The snake spring is also called the snake spring, mainly because the shape of the spring is curved like a snake and named, according to its shape can be divided into "Z" shape and "S" shape spring. This spring is mainly widely used in car seat cushions, so it is called seat spring.

5. Spiral coil spring of special-shaped spring. Scroll coil spring, also known as scroll coil spring, its effect and principle are similar to that of conical coil spring, it accepts pressure absorption and can be larger energy, but because the production is more difficult, it is only used when the space is constrained in special cases.

Six, the plate spring of special-shaped spring. Plate springs are generally made of single or multiple spring plates superimposed, with functions such as cushioning and damping. Plate springs have strong cushioning and vibration reduction functions, and are mainly used in the suspension equipment of cars, tractors or railway vehicles.

Seven, shaped spring of unequal pitch helical spring. The unequal pitch helical spring can satisfy both the small stiffness of the spring deformation and the large stiffness requirements of the large deformation, because these springs are mainly used in the suspension springs of motorcycles, small buses and high-speed engine valve springs.

Eight, shaped spring of the sheet spring. Sheet spring is also known as sheet spring, and the spring information is mostly used with spring strip (or sheet), and its process is processed in special equipment or general pressure processing machine tools, using the corresponding mold. Because of the thin thickness of sheet springs, corrugated springs and light springs, they are widely used in industry.

Nine, the line spring of special-shaped spring. Wire springs are a variety of springs made of wire with springs according to different uses, usually made of cold-drawn spring steel wire. Because the cross section of the wire spring is often circular, its load has no directional constraints, and it has the same flexural stiffness in all directions, so this wire spring is mostly used for occasions where the load is small and the load characteristics are not strictly required.

10, shaped spring of the ring spring. The ring spring is composed of the stretching spring and the connecting spring, the pitch and the turning direction of the stretching spring and the connecting spring are the same, the special tire clamp is used to clamp one end of the stretching spring and screw the connecting spring, and then the other end of the stretching spring is rotated into the other end of the connecting spring, and the turning force is used to screw the connecting spring inside the stretching spring and make the stretching spring form the ring spring.

11. Rectangle spring of special-shaped spring. The rectangular spring, referred to as the rectangular spring, is a spring with rectangular cross-section data that is often used when the installation space is constrained. Because the rectangular spring can be in the same space and deformation can obtain a larger load. Compared with the spring of circular section data, under equal space conditions, the section area of the rectangular spring is large, so the energy can be absorbed is large, and it is mostly used for heavy machinery, stamping dies or springs with particularly large stiffness.

12, shaped spring in the convex spiral compression spring. Because the two ends of this kind of spring have a small spring ring and can be embedded in the middle spring ring, a large amount of deformation can be obtained. For example, the brake spring of a convex car, which is usually in a tight state, when the car valve is opened, the spring will recover and deform, driving the brake to brake the car. Another example is the fader used by the barber when cutting hair, whose principle is the same as this, which can obtain a large amount of deformation in an effective space.
