Description
Technical Field
[0001] The utility model relates to the technical field of surface treatment, in particular to a tool for batch processing and production of beryllium bronze reed parts. Background Art
[0002] Beryllium bronze is a simple Cu-Be binary alloy with beryllium as the primary alloying element. Specialized beryllium bronzes can be formed by adding elements such as Ni, Co, Ti, and Mg to simple beryllium copper alloys. Beryllium bronze is a typical precipitation-hardening alloy. After solution-aging treatment, it exhibits excellent strength, hardness, elastic limit, and fatigue limit. It also exhibits excellent corrosion and low-temperature resistance, as well as excellent electrical and thermal conductivity. It is widely used in marine electronics, aerospace, instrumentation, and the electronics and electrical industries.
[0003] Reed parts are one of the important types of applications of beryllium bronze materials in the industrial field. The mechanical performance evaluation standards for reed parts are stable elastic coefficient, small elastic aftereffect, small elastic hysteresis and small continuous creep. Reed parts meet the mechanical performance evaluation standards, thereby ensuring that reed parts can have stable elastic stiffness and stable elastic force. After applying preload, reed parts can quickly deform to the set displacement, and the displacement changes little over time. In addition, during the process of applying preload and unloading preload, the difference in deformation trajectory is small.
[0004] At present, the processing and production process of beryllium bronze spring parts is as follows: (1) blank forming (wire cutting, laser cutting or stamping); (2) bending forming; (2) aging treatment (surface treatment).
[0005] The mechanical properties of beryllium bronze reed parts are basically achieved during the aging treatment process. The tooling used in the aging treatment process will directly affect the quality and efficiency of the aging treatment, and thus affect whether the mechanical properties of the reed parts can meet the standards.
[0006] Existing aging treatment tooling for beryllium bronze spring parts is a solid cylindrical structure or a solid prismatic structure, which is divided into two parts along the axial direction: an upper concave part and a lower convex part. The upper end surface of the lower convex part has a groove structure consistent with the external structure of the part. The two parts are used in conjunction to realize part clamping. The number of parts that can be aged is limited and cannot meet the requirements of batch processing production. In addition, the heat conduction time to the part surface is inconsistent and the conduction is uneven, affecting the efficiency and quality of the part aging treatment.
[0007] In order to solve the above technical problems, the present invention provides a tool for batch processing and production of beryllium bronze spring parts. Summary of the Invention
