Manufacturing process of bimetallic sliding bearing

Abstract

The invention discloses a manufacturing mould and manufacturing method of a bimetallic composite sliding bearing. The mould comprises an upper mould (1), a lower mould (4), a cavity (2), and a bearing (3). The manufacturing method is characterized by comprising the following steps: preparing an inner sleeve material according to the mass percentage of the following components, pre-mixing the prepared components in a high-speed mixer; further granulating and granulating in a granulation extruder to obtain the inner sleeve material masterbatch; and finally conducting curing heat treatment on a metal injection molding bearing to obtain a finished product. The mold provided by the invention is reliable in operation, has the advanategs of less energy consumption of the equipment, high speed, mass production, good product consistency, few personnel, raises the utilization rate of materials, and can effectively improve the production efficiency and reduce the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bimetal sliding bearing manufacturing process. Background technique [0002] Bimetallic sliding bearings with anti-friction materials in the radial and axial directions have the ability to bear radial and axial loads at the same time, and are widely used in large and medium-sized heavy-duty high-precision machinery and equipment. Due to the limitation of single-piece and small-batch production of large and medium-sized heavy-duty high-precision equipment, the use of conventional batch production methods to manufacture bimetallic sliding bearing blanks not only has a long manufacturing cycle, large capital investment and high production costs, but is also not conducive to large-scale production. Maintenance and repair of bimetallic bearings for medium-sized high-precision equipment. Contents of the invention [0003] The technical problem to be solved by the present inventio...
