Spring is one of the important parts in many mechanical products, and the models used in different parts are different. There are many kinds of spring, and its elasticity is used to work in mechanical parts. The spring under certain external factors, will cause fracture, deformation, relaxation and other faults, and the most common is the spring fracture Spring What are the fracture factors? The following is a detailed introduction from Zhejiang spring manufacturers.
Brittle fracture: when the spring breaks, most of them are brittle fracture. Fracture is only possible at high plastic temperatures. In this process, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle fracture.
Fatigue fracture: spring fracture under cyclic load.
Stress corrosion fracture: spring fracture is caused by tensile stress and corrosive medium.
Corrosion fatigue fracture: spring fracture occurs under the combined action of cyclic load and corrosive medium.
High content of cadmium in the brittle material.
Wear: wear is divided into abrasive, fatigue and corrosive wear.
At present, the spring industry is in the state of oversupply of low-level spring (ordinary spring), while the supply of high-end spring is greater than demand.
