Molding method of winding type slide bearing

Abstract

The invention discloses a molding method of a winding type slide bearing capable of enabling a prefabricated product to obtain high pressure in a curing process so as to guarantee the product to generate no layers and to eliminate a lot of wrinkles on the section of the product for preventing low bearing capacity. The molding method is realized through the following steps: firstly, a composite preimpregnated cloth tape is wound outside a core film to form a bearing pre-molded product; a layer of high-temperature-resistant sealing film is applied on the surface of the bearing pre-molded product; then, the whole is put into a lower mold, and is buried by fine hard particles; an upper mold is put in, and is pressurized to a preset pressure; the upper mold and the lower mold are fixedly connected to form an integrated treated part; finally, the integrated treated part is put into a sintering furnace for curing; after the curing, the integrated treated part is taken out; and the upper mold, the lower mold, the fine hard particles, the sealing film and the core film are removed to obtain the winding type slide bearing product.

Description

technical field [0001] The invention relates to a bearing forming method, in particular to a forming method of a winding sliding bearing. Background technique [0002] Traditional metal bearings are often difficult to lubricate in the fields of engineering machinery, construction machinery, port machinery, water wheel machinery, chemical light industry machinery, etc. due to heavy loads and low speed conditions, and even work under conditions that cannot be lubricated. As a result, a copper alloy inlaid solid lubricating bearing has been produced in my country to replace pure metal bearings and a thermosetting plastic bearing made of phenolic plastic. raw materials, and requires high-precision CNC machine tools and grinding machinery, so the bearing capacity is small and the production cost is high; the thermosetting plastic bearings are only suitable for working in water media such as water pumps and submersible motors, and the application field has certain limitations.
