Inclined ring spring related matters, Du Shi Cheng sent to share with you about it!

With the popularization and wide application of inclined spring equipment, inclined spring is one of the important basic parts of mechanical products. When the spring is heated to a certain temperature, its elasticity will be affected, and even segregation will be easy to break. It has the following fracture modes:

1, stress corrosion fracture: spring fracture phenomenon is caused by tensile stress and corrosive media.

2. Corrosion fatigue fracture: spring breaks under the combined action of cyclic load and corrosive medium.

3. The spring breaks under the action of cyclic load.

4, hydrogen brittle cadmium brittle, black brittle: is due to the high content of impurities in the spring material caused by the brittle break.

5, brittle fracture: most spring fracture belongs to brittle fracture. Plastic fracture is possible only at higher operating temperatures. In engineering, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle fracture

6, wear: wear is divided into: abrasive wear. Fatigue and corrosion wear fracture.

Burr or metal powder off the tilt spring, once in the hydraulic or pneumatic system, can cause severe turbulence or non-laminar flow, can clog the filter or pipe, so the hydraulic body and pneumatic components must be removed burr. In mechanical transmission systems, burrs can fall off due to vibration.

The system is stuck or the component is damaged. Sometimes burrs directly interfere with the mechanical motion of components, especially pistons or spool valves. In the process of cutting, if the burr pad is located on the base surface of the parts, after clamping interference with the false base surface contact, become point contact, seriously affecting the machining accuracy. The same goes for assembly,

The assembly is unqualified due to the presence of burrs. Swash plate spring if not removed burr, loading and unloading work parts on the machine tool or assembly processing, will scratch the worker's hand. Under high load, the sharp edge will affect the fatigue strength and adhesion with paint and other protective layers, reduce the service life of parts spring burr will also affect the appearance of parts. Based on the serious consequences mentioned above. The little spines are like rat droppings in a pot of porridge. It must be eliminated in advance to prevent future problems.
