Abstract
A water-cooling protective cover for a plasma welding machine for titanium sponge electrodes comprises an argon protective cover, an argon port, an air screen, a cooling water sleeve, a water inlet pipe, a water outlet pipe, a ceramic insulation bushing and a plasma welding gun, wherein the argon protective cover is provided with the argon port in a welding mode; the air screen is fixed inside the argon protective cover; the cooling water sleeve is embedded at one end of the argon protective cover; the water inlet pipe and the water outlet pipe are welded on the cooling water sleeve; and the cooling water sleeve is fixed on the gun head of the plasma welding gun through the ceramic insulation bushing. The water-cooling protective cover for a plasma welding machine for titanium sponge electrodes can fully cool the heat produced by the plasma welding gun in work through using the cooling water protective cover which is in a long rectangular shape, and the protection area is large. Moreover, as the cooling water sleeve is used, cooling speed is high, cooling effect is good, the welding gun and the protective cover are not hot after long time work and the welding gun can be moved in the welding process, thereby realizing continuous welding of titanium sponge electrodes under the premise of guaranteeing welding quality, improving wielding quality and work efficiency and strengthening welding intensity.
Description
Technical field
The utility model relates to the welding protection device, is a kind of titanium sponge electrode plasma welding machine water-cooled protective cover specifically.
Background branch art
The plasma welding mainly is to utilize arc column plasma heat deposite metal to realize welding, and welding temperature is high, and the arc column central temperature is up to more than 18000～24000K.Titanium is a kind of metal that at high temperature very easily reacts with airborne oxygen, nitrogen, hydrogen, must just can weld under inert gas shieldings such as argon gas or helium.The titanium sponge electrode is to be assembled by several titanium sponge electrode blocks, and only welding just can guarantee weldquality under the plasma arc high temperature of inert gas shielding.Dual mode is generally adopted in the welding of titanium sponge electrode, a kind of is to weld in the weldering case of titanium sponge electrode integral body protective gas such as argon filling or helium after exhausting vacuum, this welding manner equipment has high input, complicated operation, the cost height, but welding quality is good, is mainly used in high-end titanium products such as space flight and aviation material; Another kind is that an argon shield cover is installed on plasma gun; under atmospheric environment, the welding position is carried out the manual welding of localised protection, this mode less investment, simple to operate, cost is low; be mainly used in civilian titanium products, welding quality mainly depends on the protection effect quality of argon shield cover.
The welding gun argon shield cover of previously used plasma machine is not with cooling jacket, and after welding gun work a period of time, rifle head and argon shield cover temperature are very high, and the operator scalds easily, and the cool time of weld seam is long, causes oxidation easily.And previously used protective cover is circular, can protect area little, is mainly used in spot welding, can not realize continuous welding, and the solder joint area is little, and welding quality is difficult to control.
The utility model content
At the problem of above-mentioned existence, the utility model provides a kind of titanium sponge electrode plasma welding machine water-cooled protective cover.
The technical solution of the utility model is: titanium sponge electrode plasma welding machine water-cooled protective cover; comprise argon shield cover, argon gas interface, gas net, cooling jacket, water inlet pipe, outlet pipe, ceramic insulation cover, plasma gun; it is characterized in that: argon gas interface of welding above the argon shield cover; fix a gas net in the argon shield cover; cooling jacket is embedded in an end of argon shield cover; be welded with a water inlet pipe and an outlet pipe above the cooling jacket, cooling jacket is fixed on the rifle head position of plasma gun by a ceramic insulation cover.
Described argon shield cover is copper square shell body.
Advantage of the present utility model: the utility model adopts the water cooling protection cover; can fully cool off the caloric value that plasma gun work produces; protective cover adopts long square type structure; protection domain is big; the weld seam that welding is good can move to the room cooling of square type protective cover by slow mobile welding gun, owing to adopt cooling jacket, cooling velocity is fast; good cooling results, rifle head and protective cover non-scald on hand after the long-term work.Can mobile welding gun in welding process, therefore under the prerequisite that guarantees welding quality, can realize the continuous welding of titanium sponge electrode, improved welding quality and intensity, improved operating efficiency.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings, the utility model is further specified.
As depicted in figs. 1 and 2; argon gas interface 2 of welding above the argon shield cover 1; fix a gas net 3 in the argon shield cover 1; cooling jacket 4 is embedded in an end of argon shield cover 1; be welded with a water inlet pipe 5 and an outlet pipe 6 above the cooling jacket 4, cooling jacket 4 is fixed on the rifle head position of plasma gun 8 by a ceramic insulation cover 7.
Before the work, open cooling water valve, cooling water flows into cooling jacket 4 by water inlet pipe 5, is flowed out by outlet pipe 6.During plasma gun 8 work, the heat of rifle head high ambient temperatures plasma gas is taken away by cooling jacket 4, after cooling jacket 4 has been installed, the heat that sends in the welding process water that will be cooled is taken away, simultaneously, cooling jacket 4 can play cooling effect to molten bath and weld seam, can shorten the cool time of weld seam, has improved cooling effect.If continuous welding; can slowly move square type argon shield cover 1 and plasma gun 8 towards the welding gun direction simultaneously; molten bath and weld seam are slowly released plasma gun weldering 8 and are connect and distinguish to square type argon shield cover 1 empty position like this; in this position; weld seam still has argon shield to continue cooling, so weldquality is higher.
