The types of ends available for springs depend on the spring type since extension, compression, and torsion springs have different options regarding the types of ends they may have. Each spring has standard ends that easily conform to its type. Additionally, manufacturers offer customized ends to meet the needs of unique and unusual applications.

Flat springs are made of flat strip steel and are used in many applications and are ideally suited for applications where space is limited or where the spring can be used as part of mounting assembly. The flat spring design allows forming of specific features and profiles for a unique application and mounting location. Flat springs can be made in a variety of shape, sizes, designs and materials to work for many design applications. An experienced Lee Spring engineer knowledge in our fourslide, powerpress, and hand-forming tools can work with you from design concept through manufactured parts to assist with creating the optimal design of your custom flat spring. Wire baskets are made from a series of wires that are woven together or welded to form a shape of a basket. They can also be defined as containers that are made by use of an openwork pattern of metal... Wire Displays Closed and Square:The last coil of a closed and square compression spring is closed, making it possible to stand on end on a flat surface. The pitch of the end is reduced to form one dead coil. These are non-helical springs with geometries such as wound strips, cantilever beams, disks, and bars. The cross-section of the spring material is subjected to different types of stresses, mostly combinations of bending and torsional stresses.Chromium-Silicon Alloy (ASTM A401): These are available in cold-drawn or oil-tempered conditions. Chromium-silicon steel alloy can be heat treated to high hardness without losing much ductility. They are suitable in high impact loadings such as firearm recoil springs. Phosphor Bronze (ASTM B159): Phosphor bronze is an alloy of copper, tin, and phosphorus. This is the most widely used copper-base spring alloy. It has good electrical conductivity coupled with the ability to withstand repeated bending. However, it is are not hardenable by heat treatment. The main objective of spring design is to determine the right combination of spring geometry and material to achieve safe working stress at a practical cost. In-House Secondary Operations including CNC Machining, Vibratory Deburring, Painting, Welding & Assembly A torsion spring is a mechanical device that stores and releases rotational energy. Each end of the torsion spring is connected to a mechanical component. As the spring is rotated around its axis on one end, the winding of the spring is tightened and stores potential energy...

Investment in TechnologySprings can be made from lots of different materials, and not all are made from metal. The end-use for the spring will inevitably decide its form and the materials it is made from. Learn the difference between a titanium spring and a copper alloy spring here. Variable Pitch, Cylindrical Spring: As the name suggests, these are cylindrical springs with varying pitch. This enables the spring to have a varying spring rate, which is also desirable for dynamic applications. Extension springs are helical wound springs that are so closely coiled together to create initial tension in the coils. This initial tension creates resistance against the force applied to its ends for extension. The initial tension helps determine how closely and... Torsion Springs Coil springs called compression springs can store mechanical energy when they are compressed. These open-coiled, helical springs provide resistance to compressive loading. When these springs are... Extension Springs The use of stainless spring steels has increased and several compositions are available all of which may be used for temperatures up to 550 °F. They are all corrosion-resistant. Only the stainless 18-8 compositions should be used at sub-zero temperatures.

Lee Spring offers a wide selection of metal springs for sale. Metal springs are available in a wide range of material options, characteristics, and price ranges. Selecting the right metal spring material for a particular application is an important step when selecting a metal spring. Some considerations related to metal springs are operating temperature, regulatory requirements and corrosion resistance. Torsion spring end options – Torsion springs have a straight length of wire as their end, also referred to as a leg. The single type ending is due to the function of torsion springs, which is to deflect rotary force. Legs of torsion springs can differ in length, style, orientation, and angle, with the orientation referring to how the legs are positioned in relation to each other. These are steels with additional alloying elements such as chromium, vanadium, phosphorus, and silicon. Each element enhances different properties of steel, such as strength, hardness, and machinability. Hooke‘s law is used to model the behavior of springs. It states that the force applied to the spring is directly proportional to its deflection, provided that it is within the elastic range. To find the magnitude of the force (F), the elongation distance is multiplied by a spring rate.

High-Carbon Spring Steels in Flat Strip Form

For a given cross-sectional area of the spring, the force can be converted into stress, while the deflection can be described as strain. Hooke‘s law can then be defined as the proportionality between the stress and strain of a material. The ratio between stress and strain is called Young‘s modulus. Young‘s modulus is more extensively used to model the behavior of springs since it is an intrinsic property of a material. On the other hand, the spring constant varies with the length of spring making it an extrinsic property. High-Carbon Valve Spring Steel (ASTM A230): These are high-carbon steels with uniform quality and temper. They are drawn the same way as oil-tempered steels, but their heat treatment is more controlled. As the name suggests, they are used as valve springs in automotive and aircraft engines which require corrosion resistance, fatigue resistance, and good performance at high temperatures.

F is the force, D is the coil diameter, lowercase d is the wire diameter, Kw is the Wahl correction factor, and C is the spring index (D/d). where: T is the torque, L is the length of the wire, G is the shear modulus, and J is the polar moment of inertia of the wire cross-section. In terms of spring design variables, the linear deflection of a spring is expressed as,Extension spring end options - The loop ends of extension springs are normally closed but can be changed to hooks. There are several types of ends for extension springs that include different shaped loops, including V hooks, square, coned, eye, and very small. The standard ends for extension springs are:
