Abstract

The invention provides a metal acetabular outer cup closed-type forging die. The problems that procedures are complicated, the manufacturing cycle is long, the material utilization rate is low, filling defects are prone to being generated, adjustment of forging equipment is difficult and the production cost is high due to the fact that existing metal acetabular outer cups are manufactured by an open-type die forging process can be solved. The metal acetabular outer cup closed-type forging die includes a punch and a female die. The female die is provided with an impression penetrating in an up-down mode. The impression includes a guide cylinder, a cavity and an extrusion port which coaxially communicate with one another sequentially from top to bottom, and the shape of the cavity is matchedwith the outer shape of the acetabular outer cups. A guide part and a forming part which are coaxially arranged from top to bottom are arranged on the bottom surface of the punch, the guide part is in clearance fit with the guide cylinder, and the shape of the forming part is matched with the inner shape of the acetabular outer cups. Meanwhile, the invention further provides a metal acetabular outer cup closed-type forging method.

Description

technical field

[0001] The invention relates to the field of artificial joint processing and manufacturing, in particular to a metal acetabular outer cup closed forging die and forging method. Background technique

[0002] The metal acetabular outer cup is an artificial joint implant, which is used as a replacement for implanting the human hip joint in orthopedic replacement surgery after the human hip joint is damaged or diseased, and implanted in the patient's body to restore the physiological function of the hip joint to a certain extent , relieve pain, improve the patient's exercise needs, and improve the quality of life.

[0003] At present, the same kind of metal acetabular outer cups are manufactured by open die forging process. The forging process will produce large flashes, which need to be removed by laser trimming and milling flashes in the later stage. The process is complicated and the manufacturing cycle is long. , the consumption of raw materials is large, th...
