Stainless steel wire for high strength spring In the application of high-strength spring, the early piano steel wire is more common, but the corrosion resistance is very poor. Chromate treatment is required for rust prevention. In the past, crude steel zinc coating was given to make it self-corrosion resistant, but chromate treatment must be carried…
Coil spring and shock absorber Spiral spring is a buffer element, named after its shape like spiral. It has the advantages of no lubrication, no dirt, small weight and less space. When the impact force of the road surface to the wheel is transmitted to the coil spring, the coil spring deforms, absorbs the kinetic…
Spring original length measurement The original length of the spring is the length of the spring without any external force. It is not easy to create such an environment when doing experiments on the ground. If the spring is hung up, the spring will stretch due to its own gravity. If the spring is placed…
Characteristics of die spring In recent years, with the development of die industry, the number and variety of die springs, especially special-shaped steel wire die springs, are increasing. Special section die spring has the characteristics of large stiffness, long service life and small volume. However, the development of its design theory is relatively slow. At present,…
Fault analysis of spring machine screen not displaying When producing springs,the CNC spring machine meet the problem of non-dispaly of screem sometimes. The following are the main reason for this issue. Circuit problems If the power indicator on the display is not high, it indicates that the display does not have normal power supply. Use…
Precautions for refitting springs As far as cars are concerned, elastic elements mostly refer to coil springs. They only bear vertical loads and mitigate and suppress the impact of uneven roads on the car body. They have the advantages of small occupied space, small mass and no lubrication. However, they can not play the role…
Impact test of spring The springs used in the buffers of some construction machinery, transport vehicles and the recoilers of guns often bear impact loads in their working process. The deformation speed of the spring bearing the impact load is very fast. For example, the deformation speed of the repeater spring of some high-speed guns…
Common problems of die spring Die springs are widely used in industrial production. The following are the common problems of die spring in use. We have to pay more attention for the following problems Why does the spring break during use? a. The mandrel is too small or the spring is used horizontally, and the…
Lubrication of automobile leaf spring The lubrication of automobile leaf spring is very important. As we all know, leaf springs are composed of many steel sheets with elasticity, consistent width and thickness, and different lengths. Its function is to connect the frame and axle in the form of suspension, expose between the frame and axle,…
Factors affecting spring fatigue strength The below are the main factors,which influence the spring fatigue strength. When you producing and using springs, you have to pay attention on following issues. Yield strength There is a certain relationship between the yield strength and fatigue limit of the material. Generally speaking, the higher the yield strength of…
Process characteristics of multi strand spring Due to the limitation of product structure, multi strand spring generally has the characteristics of high strength and good performance. The material is required to guarantee the final performance in terms of strength and toughness. Therefore, its material usually adopts elastic modulus E = 206 × 103n / mm2…
Spring temperature control system We hereby wish to share the experice of Spring field temperature control system Significance of on-line infrared temperature measurement 1. Accurate temperature measurement – avoiding the unreliability of human eye observation 2. Non contact, fast response – the disadvantages of thermocouple taking away heat, destroying temperature field and slow response are…
Common materials of cold formed springs Common materials of cold formed springs ,such as compression spring, torsion spring, tension springs,can be divided into the following types according to different kinds of heat treatment processes. The first type is the material that does not need quenching and only needs stress relief annealing after spring forming. This…
Spring strengthening process Suspension spring reinforcement Thanks to the high stress lightweight design, the weight of suspension spring has been greatly reduced in recent years. It is very common for the stress of suspension spring of new models to be > 1000MPa. The service of spring under such high stress has exceeded the limit that…
The modification of Automobile Spring The coil spring is the most commonly used spring in the suspension system because it is easy to manufacture, high performance and efficiency and low price. The physical definition of spring is to store energy. When we apply a fixed force to the spring, it will deform. When we remove…
