German deprag springs deprag models deprag prices

deprag springs are helical springs that withstand axial compressive forces. The cross-section of the material used is mostly circular, but rectangular sections and multi-strand steel wires are also used. Springs generally have uniform pitch. The shapes of compression springs include cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of a compression spring. When subjected to external loads, the spring contracts and deforms, storing strain energy. Compression springs provide resistance to external compressive loads. Compression springs are generally wound with metal wire at uniform pitch and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external compressive loads (such as gravity pressing down on wheels, or body weight pressing on a mattress). That is, they push back to resist external pressure. Compression springs are generally wound with metal wire at uniform pitch and have a fixed wire diameter. In addition, there are conical compression springs, or springs combining conical and straight sections. Depending on the application area, compression springs can be used to resist pressure and/or store energy. Round metal wire is the most commonly used material for compression springs, but compression springs are also manufactured from square, rectangular, and specially shaped metal wires.

deprag spring classification

1) According to the characteristics of the load during operation, helical springs can be divided into three types: compression, extension, and torsion; 2) According to structural features, they can be divided into two main categories: cylindrical helical springs and variable-diameter helical springs; variable-diameter helical springs mainly withstand compressive loads; 3) According to shape features, they can be divided into conical, volute, concave, and convex shapes. 4) In production and use, helical springs can also be divided into two categories based on forming methods and material diameter: large helical springs and small helical springs; the former are usually hot-formed, while the latter are cold-formed. 5) Other classifications: There are many types of helical springs. By appearance, they can be divided into: ordinary cylindrical helical springs; variable-diameter helical springs. By the direction of the helix, they can be divided into: left-hand springs; right-hand springs. Variable-diameter helical springs are divided into: conical helical springs, volute helical springs, and concave helical springs. Cylindrical helical springs have a simple structure, are easy to manufacture, and are widely used. Their characteristic curve is linear, and they can serve as compression springs, extension springs, and torsion springs. When the load is large and radial dimensions are limited, two compression springs with different diameters can be nested together to form a combination spring.

1) Torsion springs: Torsion springs (torsional springs) utilize the principle of leverage. By twisting or rotating elastic materials with softness and high toughness, they possess significant mechanical energy. They are springs that withstand torsional deformation, and their working parts consist of coils that are either closely wound or spaced apart. The end structures of torsion springs are processed into various shapes of torque arms, ranging from single torsion to double torsion, and even various torsion bar deformations, depending on the design. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production such as automobiles, machine tools, and electrical appliances. 2) Compression springs: Compression springs are helical springs that withstand axial compressive forces. Springs are generally divided into uniform-pitch springs and variable-pitch springs. The shapes of compression springs include cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of a compression spring. When subjected to external loads, the spring contracts and deforms, storing strain energy. Variable-pitch springs are becoming more common and are no longer just uniform-pitch springs; variable-pitch springs can perform different functions in different environments. 3) Carbon nanotube springs: The diameter of carbon nanotube springs can reach hundreds of micrometers, while their length can reach several centimeters. Their spinning structure has broad application prospects and is expected to be applied in fields such as stretchable conductors, flexible electrodes, micro strain sensors, supercapacitors, integrated circuits, solar cells, field emission sources, and energy dissipation fibers, providing the possibility of preparing visually visible carbon nanotube electronic devices. They are also expected to be applied in medical devices, such as tension-sensing bandages. This new type of structure can also be developed into multifunctional carbon nanotube fiber composites for utilization. 4) Extension springs: Extension springs are helical springs that withstand axial tensile forces. Extension springs are generally manufactured from round cross-section materials. When not under load, the coils of extension springs are generally tightly closed with no gap. They work using the rebound force (tensile force) after extension, used to control the movement of machine parts, store energy, measure force magnitude, etc., and are widely used in machines and instruments. Their hook forms include side-hook extension springs, long-hook extension springs, British-hook extension springs, German-hook extension springs, semi-circular hook extension springs, duck-bill hook extension springs, etc. Their materials include stainless steel, music wire, high-carbon steel, phosphor bronze, beryllium copper, oil-tempered alloy spring steel, etc. 5) Air springs: An air spring is a non-metallic spring that achieves elastic action by adding pressurized air into a flexible sealed container and utilizing the compressibility of air. It can be roughly divided into two types: bladder type and diaphragm type. Air springs have excellent elastic characteristics. When used in the suspension systems of high-end vehicles, they can greatly improve vehicle smoothness, thereby significantly enhancing riding comfort. Therefore, air springs are widely used in automobiles and railway locomotives. In addition, since air springs have many advantages compared to ordinary steel springs, they are also applied in some mechanical equipment and precision instruments.

1) Ordinary disc springs, trapezoidal cross-section disc springs, conical trapezoidal cross-section. Disc springs: Simple shape and structure, widely applied. They can be used individually, in opposed pairs, in stacked combinations, or as composite disc spring groups, withstand static or variable loads, and are used as strong buffer and vibration-damping springs in heavy machinery, aircraft, artillery, and other weapons. 2) Diaphragm springs: Mainly used in automotive clutches, functioning through the combined action of separation fingers and disc springs. 3) Wave washers: Widely used in mechanical seals, further developable into spiral wave springs. 4) Slotted disc springs: Typically used in clutches, such as those in lathes, automobiles, and tractors. 5) Circular plate disc springs: The cross-section is circular plate-shaped, deforming into a truncated cone shape under load. Simple structure, high stiffness, used in applications with special requirements. 6) Spiral disc springs: Possess the dual characteristics of disc springs and helical springs, allowing for different stiffness requirements. 7) Wave cylindrical springs (wave springs): Formed by overlapping wave washers into a cylindrical shape, allowing for greater deformation.
