Abstract
The utility model provides an improved high-current plasma welding gun. An existing high-current plasma welding gun can be burnt caused by insufficient cooling water supply and unsmooth discharge of circulating hot water, because the calibres of a cooling water input pipeline and a circulating water output pipeline in a welding gun are smaller than the calibre of a water passage between a ceramic cooling water passage and a conductive cylinder in the welding gun body. The utility model improves the existing high-current plasma welding gun, the differences from the existing high-current plasma welding gun are that the calibres of a cooling water input pipeline and a circulating water output pipeline in a welding gun body are enlarged to be larger than the calibre of a water passage between a ceramic cooling water passage and a conductive cylinder, thereby guaranteeing the water supply amount of cooling water and smooth discharge of circulating hot water in the welding gun body, and greatly improving the service life of the high-current plasma welding gun.
Description
Technical field
The utility model relates to a kind of ion welding gun, particularly a kind of big electric current plasma gun.
Background technology
Big electric current plasma gun, as plasma (orifice) gas, argon hydrogen gaseous mixture is made protection gas by high-purity hydrogen, and the type of cooling of welding gun adopts water-cooled.The plasma arc that plasma gun produces is through mechanical compress effect, thermal pinch and pinch effect, make plasma column be compressed less concentration of energy, temperature is up to 10000～24000K, the center arc column reaches 18000～24000K.Because the penetrability of plasma arc is very strong, without welding wire, directly utilizes keyhole effect, realize the workpiece welding by the relative workpiece movement of plasma arc.In welding process, because welding gun temperature height must be realized water-cooled to the rifle body, therefore only secure current are unimpeded in the rifle body, could guarantee good welding quality.Present employed big electric current plasma gun, in its rifle body, adopt one section earthenware to thread a pipe as cooling water flow, but because its coolant intake pipe road and recirculated water flow out the pipe diameter of pipeline, less than formed water channel bore between ceramic cooling water channel and the conductive tube in the rifle body, therefore often because cooling water supplies quantity not sufficient, circulating hot water is discharged not smooth, burns and be directed at plasma gun.
The utility model content
Goal of the invention of the present utility model is: at present big electric current plasma gun short problem in service life, provide the improved big electric current plasma gun in a kind of effective raising welding gun life-span.
Goal of the invention of the present utility model realizes by implementing following technical proposals:
The big electric current plasma gun of a kind of modified is made up of welding gun rifle body, the rifle cap that is connected with welding gun rifle body upper/lower terminal respectively and the protection air-casing that nozzle is housed; In welding gun rifle body, be equipped with by upper cutting gun, dead ring, lower gun body from top to bottom, reach the one coupling assembling that nozzle carrier is formed, the conductive tube of dress tungsten electrode clamping bar in the top-down cavity of this assembly, being provided with, between lower gun body and conductive tube, be provided with ceramic cooling water channel, a tungsten electrode rod is housed in the cavity of internal layer tungsten electrode clamping bar from top to bottom, be arranged in the conductive tube upper end cavity on tungsten electrode clamping bar top, be provided with the spring that is sleeved on the tungsten electrode rod, the rifle cap is fixed in the tungsten electrode rod and the conductive tube suit of epimere pocketed springs in it; The ceramic centering piece that is connected with the conductive tube lower end is housed in the hypomere cavity of ceramic cooling water channel, nozzle is fixed on the nozzle carrier, the spout centering of tungsten electrode rod termination and nozzle, the protection air-casing is sleeved on outside the nozzle, is fixed with one by retainer ring and nozzle carrier and welding gun rifle body lower end; In welding gun rifle body, be respectively arranged with the plasma (orifice) gas intake line that is communicated with tungsten electrode rod cavity of living in, the coolant intake pipe road that is communicated with water stream channel between conductive tube, dead ring and ceramic cooling water channel and recirculated water flow out pipeline, and with protection air-casing and nozzle between the protection gas intake line that is communicated with of cavity; It is characterized in that described coolant intake pipe road and recirculated water flow out the pipe diameter of pipeline, greater than formed water channel bore between ceramic cooling water channel and the conductive tube in the welding gun rifle body.
Advantage of the present utility model is: because in the existing big electric current plasma gun, coolant intake pipe road and recirculated water flow out the pipe diameter of pipeline, less than formed water channel bore between ceramic cooling water channel and the conductive tube in the welding gun rifle body, therefore often since the output deficiency of cooling water and circulating hot water discharge and freely be directed at plasma gun and burn.The utility model, improved this structural design, make coolant intake pipe road and recirculated water flow out the pipe diameter of pipeline, greater than formed water channel bore between ceramic cooling water channel and the conductive tube in the welding gun rifle body, ensured the supply of cooling water; the circulating hot water that And produces when making welding gun work flows out tubes rows by recirculated water rapidly and goes out, thus the service life of having improved big electric current plasma gun.
