[0023] See Figure 1~7 , The manufacturing method of integral titanium alloy self-lubricating joint bearing inner ring extrusion molding of the present invention includes the following steps:
[0024] The first step is to machine the titanium alloy outer ring of the joint bearing according to the requirements, and adhere the self-lubricating layer to the inner surface of the outer ring to form the finished bearing outer ring 20;
[0025] The second step is to block and extrude the bearing inner ring blank 12 by blocking the extrusion die. The inner ring blank is blanked from the bar, and positioning holes are drilled at the bottom. The blocked extrusion die includes a concave die and a convex die. The concave die is separated The three-part mold 16 can slide in the dovetail groove of the backing plate 17 below it. The middle of the backing plate is provided with a blank support column 18 that extends into the lower part of the three-part mold. The tail of the three-part mold is equ...
