Abstract

The invention relates to a machining technology of a thin-wall sleeve with surfacing hard stellite. The machining technology comprises steps as follows: blanking, heat treatment, size processing before turning and welding, mounting of a welding support device, welding, mounting of a coarse grinding tool for coarse grinding of welding position excircle, semi-finish turning as well as mounting of amandrel device for accurate grinding and finish turning. With the adoption of the welding support device, the coarse grinding tool and an accurate grinding tool, welding quality is guaranteed, the problems of welding cracks and large deformation in conventional welding process are solved, the heat treatment is performed after welding, stress produced by welding is eliminated, a shaft sleeve blankis subjected to heat treatment, mechanical properties of materials are guaranteed, the problem of deformation of the shaft sleeve in the grinding process of the conventional shaft sleeve with thinnerwall is solved, and machining precision is greatly improved.

Description

technical field

[0001] The invention relates to a processing technology of a thin-walled shaft sleeve. In particular, it relates to a processing technology for stacking and disassembling Stellite hard alloy thin-wall sleeves. Background technique

[0002] Thin-walled large-scale bushings are frequently used in power plant circulation springs. The bushings used in power plant circulation springs have higher requirements on the surface hardness, wear resistance and machining accuracy of the bushings, and the wall thickness of the bushings is often required to be thicker than the outer surface. Stellite carbide with extremely high welding hardness.

[0003] In the prior art, when the thin-walled shaft sleeve is processed, it is very difficult to weld the outer surface of the shaft sleeve with Stellite hard alloy, and the welding process is prone to cracks and the deformation is difficult to control; and the shaft eclipse length Longer and thicker wall, it is difficult to cont...
