Technical field
This utility model relates to technical field of welding equipment, is specially a kind of novel plasma pile of grounds welding gun.
Background technology
Plasma arc powder surfacing is to utilize plasma arc as thermal source, and metal alloy powders deposition heap is soldered to surface of the work
A kind of metal solder and surface modification technology.Plasma arc is the high property of the mechanical compress through torch neck and electromagnetic compression
Energy electric arc, has electric current density high, and therefore the feature that energy is high has speed of welding fast, and the feature that welding material is wide, for one
The superalloy powder of a little infusibilities also can well weld, and has a wide range of applications at welding field.
The powder feeding structure of existing plasma arc powder surfacing rifle mostly is straight tube powder feeding, and powder feeding pipe runs through the rifle up and down of welding gun
Body, powder feeding flexible pipe docks on rifle top with powder feeding pipe, causes powder feeding pipe to occupy space relatively big, and field of employment is subject to bigger restriction.
Also having a kind of powder feeding structure to enter lower gun body for single powder feeding pipe plug flat, and the powder feeding circuit UNICOM within lower gun body, due in gun body
Powder feeding channel design in portion's is complicated, the phenomenon of stifled powder easily occurs.
The most existing plasma arc powder surfacing rifle mostly is packaging, and the volume of rifle is the thickest, uses for a long time
The most easily occurring that electrical insulation properties declines, the shortcoming that water, hermetic seal effect decline, in order to solve these problems, therefore, Wo Menti
Go out a kind of novel plasma pile of grounds welding gun.
