  What are the main reasons for the fracture of precision springs?Electronic connector price(图1)

  Precision springs are one of the important parts in many mechanical products. There are many types of them, which can be used in medical equipment, mobile phones, aerospace and other precision equipment industries. The main reason for the fracture of precision springs is due to the oxidation, deformation, and overload of the spring. And so on.

  The main spring failure modes are: fracture, deformation, slack, and wear. Among them, the main analysis is fracture and deformation (relaxation). The reasons for spring fracture are as follows. We will conduct specific analysis according to each different situation.

  1. Brittle fracture: most of the spring fractures are brittle fractures. Only when the working temperature is high, plastic fracture may occur. In engineering, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle fracture.

  2. Fatigue fracture: the fracture of the spring under cyclic loading.

  3. Stress corrosion fracture: the spring fracture phenomenon caused by the combined action of tensile stress and corrosive media.

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

  5. Hydrogen embrittlement, cadmium embrittlement, black embrittlement: brittle fracture caused by high impurity content in the spring material.

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