Efficient roller wheel tooth hard alloy surfacing system and surfacing method

Abstract

The invention discloses an efficient roller wheel tooth hard alloy surfacing system and a surfacing method. The efficient roller wheel tooth hard alloy surfacing system comprises an electric control box, a cold water circulation box, a welding machine box, a rotary machine tool platform, a welding machine moving platform, a wire feeding disc and a welding bent gun. The welding machine moving platform comprises a horizontal sliding supporting beam, a sliding supporting arm and a welding gun supporting seat. The horizontal sliding supporting beam is horizontally arranged above the outer side of the rotary machine tool platform, the sliding connecting end of the sliding supporting arm is horizontally perpendicular to the horizontal sliding supporting beam and is connected to the upper surface of the horizontal sliding supporting beam in a sliding manner, the free end of the sliding supporting arm horizontally extends outwards to the position over the rotary machine tool platform, the welding gun supporting seat is connected to the sliding supporting arm in a sliding manner, a wire feeding mechanism is arranged on the welding gun supporting seat, and the welding bent gun is connected to the portion, on one side of a wire feeding outlet of the wire feeding mechanism, of the welding gun supporting seat. According to the system and the method, wear resistance of roller wheel teeth is improved through the method of surfacing of a high-wear-resistance hard alloy layer, and the surfacing process is simple, convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of surfacing welding, in particular to a high-efficiency roll gear tooth cemented carbide surfacing welding system and a surfacing welding method.

Problems solved by technology

The existing electrode manual arc welding surfacing welding has low productivity and high dilution rate, and it is difficult to obtain a thin and uniform surfacing layer; the oxyacetylene flame surfacing welding method has low productivity and high labor intensity, and is only suitable for small parts and small quantities of surfacing welding; The arc welding surfacing method cannot be used for multi-directional surfacing welding and granular hard alloy surfacing welding. The cost of plasma arc surfacing welding equipment is high, and there is strong arc radiation and ozone pollution.
