The application discloses a forming method for concave thin plate corrugated stainless steel parts, which comprises die assembling, stamping buffer layer laying, stamping preforming, stamping forming and shearing correction. By using the forming method, the existing punch is used, in the stamping preforming process, the stamping buffer layer is laid, the step-by-step pressing mode is adopted, the stamping buffer layer can control the material flow problem, so that the material uniformity is achieved; in the stamping forming, the die is replaced, and the one-time pressing forming is adopted, which can effectively solve the technical problem that the boundary of the corrugated area is prone to wrinkling, and can improve the forming efficiency, so as to improve the qualified rate of part forming, ensure the product forming quality, greatly reduce the processing cost, and be applied to the processing of the parts prone to wrinkling, and is convenient to operate and suitable for popularization and application.

This utility model discloses a multifunctional massage chair frame. The backrest frame is connected to the main body of the chair frame via a backrest guide rail. One end of the backrest push rod is hinged to the main body of the chair frame, and the other end is hinged to the five-claw base. The leg support frame is movably connected to the main body of the chair frame. One end of the leg-lifting push rod is hinged to the main body of the chair frame, and the other end is connected to the first connecting rod via a connecting rod. The first connecting rod is connected to the third connecting rod via a second connecting rod. The third connecting rod is connected to the leg support frame. The leg support frame is connected in the middle, and a leg sliding groove is provided on the side of the leg support frame. The leg sliding groove is connected to one end of the leg-lifting connecting rod assembly, and the other end of the leg-lifting connecting rod assembly is connected to the main body of the chair frame. This utility model achieves synchronous and coordinated movements of backrest lifting and leg raising and extension through a linkage mechanism, effectively improving the user experience, protecting the leather cover structure, and enhancing operational flexibility and user comfort.

The invention discloses a high-performance ultra-thin and ultra-light titanium alloy vapor chamber and a preparation method thereof.According to the preparation method, the preparation process of the vapor chamber is improved, a liquid absorption core and an upper cover are fixed in advance and sintered, and heat treatment is conducted after the upper cover and a lower cover are welded and fixed; vacuum high-temperature sintering is matched with low-temperature heat treatment, the wrinkling problem caused by expansion coefficient difference can be solved, the yield of the vapor chamber is improved, the formed vapor chamber is excellent in heat transfer performance and stability, passivation is carried out through acid pickling and baking, the problem of performance degradation of the vapor chamber is solved, and the production cost is reduced. The upper cover and the lower cover of the vapor chamber are both made of titanium alloy materials, compared with conventional stainless steel materials, the weight can be greatly reduced, and the heat transfer performance is excellent.
