Abstract

The invention discloses a forging method of a TC4 cross-shaped special-shaped wing plate tibia support artificial joint implant. The forging method mainly comprises the steps of blanking, surface treatment, spraying, extrusion, surface treatment, spraying, pre-forging, surface treatment, finish forging, annealing and the like. The method can effectively solve the technical problems that a qualified TC4 cross-shaped special-shaped wing plate tibia support cannot be produced through an existing precision forging method, and the TC4 cross-shaped special-shaped wing plate tibia support produced through a precision casting method is not high in smoothness, poor in mechanical property and poor in size precision.

Description

technical field [0001] The invention relates to the technical field of artificial joint forging processing, in particular to a forging method of a TC4 cross special-shaped wing plate tibial support artificial joint implant. Background technique [0002] The cross shaped wing plate tibial tray artificial joint implant is a substitute for the injured tibial tray in the human knee joint. It can be implanted through surgery to restore joint function and improve the quality of life of patients. TC4 material has excellent corrosion resistance, high strength, low elastic modulus, no toxic side effects, and good biocompatibility. It has a wide range of applications in orthopedic implants. [0003] figure 1 It is a structural schematic diagram of a cross-shaped wing plate tibial tray artificial joint implant, which includes wing plate 1 and base plate 2, the base plate is U-shaped, and there are 4 wing plates perpendicular to the base plate, and the thickness of the wing plates is o...
