Plasma alloy powder cladding equipment

Abstract

The invention discloses plasma alloy powder cladding equipment, and relates to the technical field of plasma welding. The problem of synchronism is solved. The device specifically comprises a base, the top of the base is connected with a cladding welding assembly through a three-dimensional moving part, the cladding welding assembly comprises a material containing hopper, a plasma welding gun and a supporting seat, the material containing hopper is fixedly installed on the outer wall of the supporting seat, and the plasma welding gun is fixedly installed on the outer wall of a bottom outlet of the material containing hopper; a supporting plate is fixedly installed on the outer wall of the supporting seat, an inserting plate is slidably connected to the outer wall of one side of the supporting plate through a sliding rod, the inserting plate is slidably connected to the inner wall of the containing hopper, a through hole with the same inner diameter as an outlet of the containing hopper is formed in the inner wall of the inserting plate, and a limiting plate is fixedly installed on the outer wall of the sliding rod. Powder feeding of the alloy powder and starting and stopping of the plasma welding gun are completely synchronous, and the situation of electric energy waste or alloy powder waste can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of plasma welding, in particular to a plasma alloy powder cladding equipment. Background technique [0002] Plasma alloy powder cladding technology is a cladding method that uses the plasma arc as a heat source to melt the added metal and make it and the base metal as a metallurgical combination. It uses the tungsten electrode of the welding torch as the negative electrode of the current and the base as the current. The plasma generated between the positive electrodes is used as heat, and the heat is transferred to the surface of the workpiece to be welded, and the welding powder is sent to the heat energy area, which is melted and deposited on the surface of the workpiece to be welded, so as to achieve the strengthening and protection of the surface of the part. Hardened cladding process. [0003] After searching, the Chinese patent publication number is CN205133734U, which discloses a plasma alloy powder ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents have the following disadvantages: the opening and closing of the welding torch and the powder feeder are not disclosed. With reference to the prior art, the opening and closing switch of the welding torch circuit and the electromagnetic valve on the powder feeder can be used to control, but this control makes the welding torch The opening and closing are completely independent of the powder feeding opening and closing of the powder feeder. When electric control or human control is used, the timing will be misplaced, resulting in waste of electric energy of the welding torch or waste of alloy powder.
