Problems solved by technology

[0005] Due to the high environmental requirements for sintering of self-lubricating 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 period of time. In order to improve efficiency, there are The manufacturer came up with a method of using galvanized steel sheets as the isolation layer between the layers of copper-plated metal sheets to achieve multi-layer sintering. However, due to the close combination of self-lubricating bearing sheets and galvanized steel sheets during the sintering process, the layer-to-layer gap cannot be guaranteed. The indirect heat distribution and the uniformity of the sintering atmosphere reduce the performance of the sintered product and basically cannot be applied
[0006] Therefore, it is urgent to invent a device for sintering of multi-layer self-lubricating bearing plates to solve the problems of low sintering efficiency and unstable sintering quality of existing self-lubricating bearing plates

Abstract

The invention discloses a self-lubricating bearing plate sintering method and a plate containing frame used in the method. The plate containing frame used for sintering of a self-lubricating bearing plate comprises two to six layers of plate containing layers. The plate containing layers comprise supporting rods and connecting rods. The supporting rods are connected through the connecting rods. The two ends of each supporting rod are provided with fixing pieces which are in a regular three-dimensional shape. The fixing pieces are provided with concave surfaces with openings facing upwards or downwards. The fixing pieces of each plate containing layer can be clamped into the concave faces of the fixing pieces of the adjacent plate containing layer in the plate containing frame. According to self-lubricating bearing plates sintered through the plate containing frame, the performances between the layers of plates and between all the parts of the plates of each layer are consistent and are equivalent to the performance of single-layer sintering plates, and defective products do not exist. The problems that the sintering efficiency of the plates is low and sintering quality is not stable in the prior art are successfully solved.

Description

technical field [0001] The invention relates to a metal sintering method, in particular to a self-lubricating bearing plate sintering method and a plate holder used in the method. Background technique [0002] Self-lubricating bearing plates are used in the production and processing of sliding bearings and are based on metal plates sintered with copper alloy powder. Self-lubricating 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 self-lubricating bearing plate are especially suitable for heavy load, low speed, reciprocating or swinging, etc., which are difficult to lubricate and When forming an oil film, it is mainly used in the production of three types of products: boundary lubrication bearings, oil-free lubrication bearings, and bimetallic bearings. At present, the products have been widely used in construction machinery, automobil...
