Problems solved by technology

[0005] Due to the high environmental requirements for the sintering of sliding bearing plates, the existing technology is generally single-layer sintering. The production quantity per unit time of this method is low, and it cannot reach a high processing capacity in a short time. In order to improve efficiency, some manufacturers I came up with a method of using galvanized steel sheets as isolation layers between layers of copper-plated metal sheets to achieve multi-layer sintering. However, due to the close combination of sliding bearing sheets and galvanized steel sheets during the sintering process, it is impossible to ensure the heat between layers. The distribution and uniformity of the sintering atmosphere, thereby reducing the performance of the sintered product, basically cannot be applied
[0006] Therefore, it is urgent to invent a device for sintering of multi-layer sliding bearing plates to solve the problems of low sintering efficiency and unstable sintering quality of existing sliding bearing plates

Abstract

The invention discloses a sliding bearing plate sintering method and a supporting frame used in the method. The supporting frame comprises discharging layers A and discharging layers B. Each discharging layer A comprises a supporting rod and a connecting rod, wherein fixing parts are arranged at the two ends of the supporting rod and are regularly stereoscopic; each discharging layer B comprises a supporting rod and a connecting rod, wherein the supporting rod is connected with the connecting rod, and fixing parts are arranged at the two ends of the supporting rod and are regularly stereoscopic; the fixing parts of the discharging layers B can be clamped into the fixing parts of the discharging layers A, the discharging layers A and the discharging layers B are overlapped, and the total layer number of the discharging layers is 2-12. According to the sliding bearing plates sintered through the supporting frame, the performance of plates and the performance of parts of each plate are consistent, and the problems that the plate in the prior art is low in sintering efficiency and unstable in sintering quality are successfully resolved.

Description

technical field [0001] The invention relates to a metal sintering method, in particular to a sliding bearing plate sintering method and a bracket used in the method. Background technique [0002] Sliding bearing plates are used for the production and processing of sliding bearings, based on metal plates sintered with copper alloy powder. The sliding bearing plate has the characteristics of high load capacity, impact resistance, high temperature resistance, strong self-lubricating ability, corrosion resistance, etc. The products made of sliding bearing plate are especially suitable for heavy load, low speed, reciprocating or swinging, etc., which are difficult to lubricate and form oil film It is mainly used in the production of boundary lubricated bearings, oil-free lubricated bearings and bimetallic bearings. At present, the products have been widely used in construction machinery, automobiles, plastic molding machinery, hydraulic components, logistics port machinery, punc...
