Problems solved by technology

[0002] The reel is a relatively important part in the wire drawing machine. The requirements for it are that the inner and outer circles should be concentric, the out-of-roundness of the outer circle should be small, and it should be wear-resistant and increase the service life. The existing technology is to use spray welding, spray welding The rear reel is not processed, so the deformation and out-of-roundness of the reel directly affect the quality at high temperature

Abstract

The invention relates to a winding drum overlaying technique of a wire drawing machine, comprising the following steps of: before welding a winding drum, firstly turning a working surface of the winding drum according to abrasion requirements; fixing the winding drum on a rotary shaft, when mounting, positioning as an inner hole of the winding drum, adjusting the position to lead the working surface of the winding drum to be vertical to the position of an overlaying gun; preheating; overlaying; keeping warm after overlaying; and naturally cooling to room temperature. The invention has the advantages that an overlaying technique is used, the thickness of overlaying can be set randomly, after overlaying, the winding drum can be fine-processed, the deformation and the ellipticity of the winding drum can be minimal; and the invention has simple processing and convenient operation.

Description

technical field [0001] The invention relates to a surfacing welding process for a reel of a wire drawing machine, belonging to the technical field of surfacing welding. Background technique [0002] The reel is a relatively important part in the wire drawing machine. The requirements for it are that the inner and outer circles should be concentric, the out-of-roundness of the outer circle should be small, and it should be wear-resistant and increase the service life. The existing technology is to use spray welding, spray welding The rear reel is not processed, so the deformation and out-of-roundness of the reel directly affect the quality at high temperature. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a surfacing welding process for wire drawing machine reels that can reduce the deformation of the inner and outer circles of the reel and increase the service life of the reel.
