[0023] specific implementation plan
[0024] Such as Figure 1 to Figure 5 As shown, a near-net-shape manufacturing method of an automobile sliding bearing thrust ring is: use a seamless steel pipe as the steel backing of the sliding bearing thrust ring, and first press the thickness and thickness of the steel backing of the sliding bearing thrust ring Select a seamless steel pipe with the same wall thickness and inner hole diameter for the inner hole, then calculate the length of the seamless steel pipe according to the outer diameter of the sliding bearing thrust ring, and cut a section of the seamless steel pipe horizontally as the steel lining of the sliding bearing thrust ring Backing material.
[0025] Put the steel backing material 6 in the lower mold 7 of the axial rolling machine for rotary processing, the lower mold moves up and feeds during processing, and rotates with the upper mold 5 of the rotary rolling machine with an eccentric swing angle of 1.5°-5° When ent...
