Description
Technical field
The invention belongs to technical field of welding equipment, relate to a kind of full-automatic pipe end argon arc welding machine.
Background technology
Argon arc welding technology is on the basis of the principle of conventional arc weldering; utilize argon gas to the protection of metal wlding; logical excessive current makes wlding on welded base material, be melted into liquid formation bath; welded metal and wlding is made to reach a kind of solder technology of metallurgical binding; owing to constantly serving argon gas in high-temperature fusion welding; wlding can not be contacted with the oxygen in air, thus prevent the oxidation of wlding, therefore can soldering stainless steel, iron class five metals metal.Argon arc welding is divided into metal argon arc welding and non-melting electrode argon arc welding two kinds according to the difference of electrode.The application of non-melting electrode argon arc welding widely; its operation principle and feature: non-melting electrode argon arc welding is that electric arc burns between non-melt pole (normally tungsten electrode) and workpiece; a kind of inert gas (conventional argon gas) of metal chemically reactive of getting along well is flow through around welding arc; form a protection gas hood; the high-temperature metal of tungsten electrode end, electric arc and molten bath and the proximity thermal zone of influence is not contacted with air; the anti-oxidation of energy and absorption pernicious gas; thus forming fine and close welding point, its mechanical property is very good.
It is large that argon arc welding technology has current density, and heat is concentrated, and deposition rate is high, and speed of welding is fast, the advantages such as easy arc striking.But, argon arc welding technology because arc light is strong, flue gas is large, so will strengthen protection.
Because argon arc welding technology possesses above-mentioned advantage, in the prior art, people utilize argon arc welding technology at the welding edges pipe cap of steel pipe usually, so just need to form annular solder between the end and pipe cap of steel pipe, for this annular solder operation, very high requirement is proposed to the technology of operator.And existing argon arc welding technology needs manually to control, and automaticity is lower.
Owing to there is above-mentioned problem, at present, people have developed a kind of automatic annular solder technology, through retrieval, as Chinese patent literature discloses a kind of full-automatic circular seam welder [patent No.: ZL201220073120.0; Authorization Notice No.: CN202461769U].This full-automatic circular seam welder, comprise dolly, argon arc welding machine, body and motor, roller is filled below dolly, argon arc welding machine and body are housed above dolly, control cabinet and cross slid platform facility body are equipped with, cross slid platform facility connect welding gun, welding gun connects one end of sling, the other end of sling connects argon arc welding machine, the right side of dolly is provided with a supporting construction, above supporting construction, motor, reduction box, driving wheel, driven pulley is housed respectively, and motor connects reduction box, reduction box connects driving wheel, support bus on driving wheel and driven pulley.This full-automatic circular seam welder structure is simple, easy to use, improves production efficiency.
In this full-automatic circular seam welder, its welding object is in steel pipe under level, steel pipe can rely on the gravity of himself to be close on driving wheel and driven pulley, and rely on driving wheel, friction between driven pulley and steel pipe, when driving wheel rotates, drive steel pipe and driven pulley to rotate, thus the end of steel pipe is welded.But, if steel pipe is vertically placed, steel pipe will easily spin off from driving wheel and driven pulley, be not easy to welding, so, for those skilled in the art, need to grind and can improve existing full-automatic circular seam welder, be beneficial to steel pipe when being under vertical state, still can stablize, weld efficiently.
