Mobile induction heating device and its application in defect repair of bimetal bushing

Abstract

The invention provides a mobile induction heating device and an application thereof in dual-metal lining defect repair. A heating device comprises an epoxy resin insulation frame, a multilayer induction coil, an induction coil liner and a traveling device; the multilayer induction coil is fixed on the epoxy resin insulation frame, the multilayer induction coil comprises induction coil units and a connecting component, the induction coil unit is composed of induction coils and an epoxy resin plate sleeving the inner side of the coil, a glass tape is wound on each of the outer layers of the induction coil and the connection component, and the insulation varnish is dip-coated on the glass tape, and the connection component is used for connecting interfaces of two adjacent induction coils; a plurality of induction coil units are orderly sleeved to form the multilayer induction coil; the induction coil liner is arranged in the multilayer induction coil; and the travelling device comprises a support rod and a pulley. Through the adoption of the application of the mobile induction heating device in the defect repair of the dual-metal lining, a copper alloy layer on the steel backing copper alloy lining can be rapidly heated, not only is the chemical component of the alloy layer guaranteed, but also the security in the operation process can be guaranteed.

Description

technical field [0001] The invention relates to a process for repairing casting defects of bimetallic bushings, in particular to a mobile induction heating device and its application in repairing defects of bimetallic bushings, and belongs to the field of casting defect repairing. Background technique [0002] Bimetallic bushings, such as steel-backed copper alloy bimetallic bushings, use steel backing as a carrier, which can not only bear high loads, but also maintain the same linear expansion coefficient as the base; steel-backed copper alloy bimetallic bushings use excellent copper The alloy sliding bearing material is the lining layer, which can form a good friction pair with various quenched shafts, has good inlay and running-in properties, and can work effectively under oil lubrication at high speed and oil-free lubrication at low speed. [0003] At present, there are generally static casting methods, powder sintering methods, conventional centrifugal casting methods, ...

AI Technical Summary

Problems solved by technology

[0004] The quality of steel-backed copper alloy bimetallic bushings directly affects the safety of locomotives, airplanes, and automobiles. and other processes to repair casting defects. Products with casting defects such as pores, slag inclusions and cracks are generally scrapped, which will cause a lot of economic losses
