Springs are the most widely used

- Jun 22, 2018 -

Compression spring: The most widely used, in production, around the separate spiral coil, so that each circle has a gap (pitch) in order to force contraction, maintaining the tension to the ends of the extension. Under the maximum load, can not be completely Compression, must maintain the gap between the effective number of cycles, so as to avoid friction or other substances embedded, causing fatigue damage. Spring free length should be equal to the actual length of the spring plus gap, plus the amount of deformation. Compression spring to increase the contact surface, the surface should be Flatten to obtain 60~80% contact surface. The shape of the end has a variety of: both ends of the circle, both ends are equal.
It is divided into circles, because it can withstand pressure, both ends can be open or closed or flat or flat. Compression spring is the first type of variant spring, from the straight type, tapered to shrink, convex waist shape, Even all variants of the tail end can be shaped according to design. Compression springs are the most widely used of all types of springs, and have a wide range of applications in electronics, motors, computers, information, steam locomotives, bicycles, and hardware tools. , gifts, toys, and even defense industries, because of its design and principles easy to grasp, manufacturing control is also the most simple.
Stretching springs: The coils are wound into spiral coils or pitch rings that are in close contact with each other and are extended outward by external forces to maintain the force of contraction in the middle.
There are many types of puller hooks: British hooks, German hooks, side ear hooks, fish tail hooks, etc. Tension springs are typical of springs, ie springs, from straight barrels to various variants and even hooks. All kinds of shapes can be shaped according to design. The tension spring is the reverse use of the compression spring. The application range is generally less than the specific product category, but the operation control is one level higher than the compression spring.
Torsion springs: Torsion springs are divided into single torsion springs and double torsion springs. Springs are usually inserted into pins or shafts. When subjected to external forces, a torsional force is generated according to the axis of the spring, which causes the springs to be tightened or loosened. Torsion spring is divided into outer double twist and inner double torsion spring.
