Tension Spring Is The Most Widely Used

- Jul 27, 2017 -


Tension spring is a widely used elastic part, it has the characteristics of easy deformation, large elasticity and so on. The main functions of the machine are as follows:

1, mitigation of shock and absorption of vibration: this kind of tension spring has a large elastic deformation ability, can absorb vibration and impact energy. such as cars, trains in the buffer tension spring, coupling in the suction tension spring and so on.

2, control mechanism movement: this kind of tension spring requirements in a certain deformation range of the force change little. such as internal combustion engine valve tension spring, Tension Spring clutch control tension Spring, automatic machine tool cam mechanism of tension spring and so on.

3, Storage energy: This kind of tension spring requires both a greater flexibility, but also a more stable force. such as clock tension spring, gun tension spring, automatic machine tool in the automatic return device in the tension spring, and so on.

4, the size of the measuring force: this kind of tension spring requires the linear relationship between force and deformation. such as the tension spring in the dynamometer and tension spring.

Tension springs of many kinds, according to the different load can be divided into tensile force Spring, compression tension spring, torsion tension spring and bending tension spring. According to the shape of tension spring can be divided into: spiral tension spring, butterfly tension spring, annular tension spring, coil spring, plate tension spring.

Tension spring is a kind of mechanical part that uses elasticity to work. The parts made of elastic materials are deformed under external forces, and then the original condition is removed after the external force. Also "tension Spring". It is usually made of tension spring steel. Tension Spring Tension spring types of complex and diverse, according to shape, mainly spiral tension spring, scroll tension spring, plate tension spring, special tension spring.

According to the nature of stress, tension spring can be divided into tensile force Spring, compression tension spring, torsion spring and bending tension spring, according to shape can be divided into disc tension spring, annular tension spring, plate tension spring, helical tension spring, cut cone scroll tension spring and torsion bar tension spring, according to the production process can be divided into cold coil tension spring and hot coil tension spring. Ordinary cylindrical tension spring is easy to manufacture, Tension Spring and it can be made into various types according to the condition of loading. The manufacturing material of tension spring should have high elasticity limit, fatigue limit, impact toughness and good heat treatment performance, commonly used are carbon tension spring steel, alloy tension spring steel, stainless tension spring steel and copper alloy, nickel alloy and rubber. The manufacturing method of tension spring has cold roll method and hot coil method. Tension spring wire is less than 8 mm in diameter than the general cold roll method, greater than 8 mm by the heat coil method. Some tension springs are made after the pressure or shot peening treatment, can improve the tension spring bearing capacity.

Tension spring is one of the important mechanical parts, as a mechanical element with elastic, it is widely used in a variety of mechanical devices and institutions. It is usually made of tension spring steel, the type of tension spring is complex and diverse, tensile spring can be divided into tensile force Spring, Tension Spring compression tension spring, torsion tension spring and bending tension spring according to force nature. According to the shape can be divided into helical tension spring, scroll tension spring, plate tension spring and torsion bar tension spring, as shown in Fig. 1; According to the production process can be divided into cold coil tension spring and hot coil tension spring. It mainly has the following functions: Measuring force, measuring current size, Tension Spring controlling mechanical motion, storing energy, absorbing vibration or impacting energy, etc.
