Abstract
The invention relates to the field of welding, in particular to an air-cooled type automatic welding gun with bottom build up welding. The welding gun comprises a gun body. The outer diameter of the gun body is not larger than 15 mm. The lower half section of the gun body inclines towards the upper half section. An included angle of 5-10 degrees is formed between the lower half section and the upper half section of the gun body. An air inlet is formed in the side face of the upper portion of the gun body. An air channel communicated with the air inlet is arranged in the gun body. By changing a water-cooled system of a conventional automatic welding gun into a system where protection gas protects a melting pool and cools the welding gun at the same time, the appearance of the welding gun is reduced, and bottoms of extra-small-caliber deep holes are automatically welded; the welding gun is simple in structure, convenient to use and carry and high in automation degree.
Description
Technical field
The present invention relates to welding field, the ventilation type automatic welding gun of particularly built-up welding bottom a kind of special small-caliber deep hole.
Background technology
Built-up welding is process fast as the one economy of material surface modifying, during the manufacture being applied to industry-by-industry part is more and more widely repaired.Built-up welding is the welding procedure of carrying out the function metals layers such as deposition one deck is wear-resisting, anti-corrosion, heat-resisting on the surface of workpiece or edge, and built-up welding, to enhancing product performance, has reduced costs significant economic benefit.
Be less than the carbide alloy sealing surface wide along limit built-up welding 8-10mm bottom 30mm small-caliber deep hole, 6-8mm is high, what adopt at present is all manual electric arc welding substantially.Because as adopted automatic welding, the structure of welding gun is made up of a few part of the body of a gun, wire feed and water cooling, diameter itself is comparatively large, and current deep hole welding gun minimum diameter is 28mm, cannot complete automatic welding in below 30mm small-caliber deep hole.
Summary of the invention
For overcoming the deficiencies in the prior art; the invention provides a kind of ventilation type automatic welding gun of built-up welding bottom special small-caliber deep hole; the cooling system of Butt welding gun improves; protecting gas cooling welding tool while protecting molten bath to reduce welding gun profile by adopting in hole, realizing completing automatic welding bottom special small-caliber deep hole.
The ventilation type automatic welding gun of the present invention's a kind of bottom built-up welding, comprise the body of a gun, described body of a gun external diameter is not more than 15mm, described body of a gun lower semisection favours upper semisection, described body of a gun lower semisection and upper semisection form 5-10 ゜ angle, the upper side of the described body of a gun is provided with gas feed, is provided with the gas passage be connected with gas feed in the described body of a gun.
Further, in the described body of a gun, center is provided with ignition tip.
Concrete, described ignition tip through the body of a gun, and stretches out top and the bottom of the described body of a gun.
Further, the quantity of described gas passage is two, is located at the both sides of ignition tip respectively.
Particularly, described gas feed is cold gas and the import of protection gas.
Particularly, described gas passage is cold gas and protection gas passage.
Further, the top of the described body of a gun is provided with screw thread, and side is provided with screw thread near described top.
The invention has the beneficial effects as follows: the welding gun of existing built-up welding bottom small-caliber deep hole is all the manual welding that adopts substantially; this ventilation type automatic welding gun can cool by Butt welding gun again while that the water-cooling system of the automatic welding gun of routine on one side being carried out protection to molten bath instead by protection gas; thus reduce the profile of welding gun; solve and be difficult to the problem realizing automatic welding bottom special small-caliber deep hole; and it is simple to have structure; use, easy to carry, the advantage that automaticity is high.
