Special-shaped springsWhat are the common types of special-shaped springs:
(1) Variable diameter helical spring: Used in some special occasions, the material of variable diameter springs is generally round cross-section material, mostly bearing compressive loads.
(2) Leaf springs: This type of special-shaped spring is made from spring strip (or sheet) material, processed with corresponding molds on specialized equipment or general pressure processing machines. The material thickness of leaf springs, wave springs, and light springs is relatively thin, while the material thickness of medium or large disc springs is often relatively thick. This type of special-shaped spring is also widely used.
(3) In situations with limited installation space, special-shaped springs made from rectangular cross-section materials are often used because springs made from rectangular cross-section materials can achieve greater loads under the same space and deformation compared to round cross-section materials. This type of special-shaped spring has a larger cross-sectional area in the same space, thus absorbing more energy. It can be used for heavy machinery, stamping molds, or springs with particularly high stiffness.
(4) Disc springs are small in volume and light in weight, widely used for cushioning and shock absorption, commonly found in stamping molds, valve clutch fasteners, and petroleum and geological engineering machinery.
(5) Helical compression springs with a raised middle can achieve significant deformation because the smaller coils at both ends can nest into the middle coil. For example, some raised automotive brake springs are always in a tensioned state. When the car valve opens, the special-shaped spring restores its deformation and drives the brake to stop the car. Hair clippers also utilize the characteristics of convex helical springs to achieve large deformation and stress within effective space.
(6) Spiral coil springs have a similar function to conical spiral springs, capable of absorbing a large amount of energy under pressure. Due to their manufacturing difficulty, they are only used in special occasions where space is limited. Flat spiral springs have many turns and large deformation, allowing them to store significant energy, mainly used in compression springs and energy storage components in instruments.
(7) Steel plate springs can be made from single-piece spring steel plates or multiple stacked plates, offering good cushioning and vibration reduction performance. Multi-layer steel plate springs with strong vibration reduction performance are mainly used in suspension systems for automobiles, tractors, and railway vehicles.
(8) Unequal pitch helical springs are mainly used for suspension springs in motorcycles and microcars, as well as valve springs in high-speed engines. On the same spring, they can meet the requirements for low stiffness when deformation is small and high stiffness when deformation is large. Unequal pitch springs precisely meet these special requirements.
(9) Torsion bar springs are essentially straight rods made from elastic materials under torque. They have a high energy density per unit volume of deformation and are mainly used in suspension systems for various vehicles.
(10) Wire springs are various linear special-shaped springs made from spring wire, generally made from cold-drawn spring steel wire. Wire springs are often used in situations with smaller loads where there are no strict requirements on load characteristics. The cross-section of wire springs is usually round, so the load is not directionally restricted and has the same bending stiffness in all directions.
