Abstract
The utility model relates to a welding gun, in particular to a high temperature resistant metal inertia gas automatic welding gun, and belongs to the technical field of welding. The high temperature resistant metal inertia gas automatic welding gun solves the problem that a welding gun cannot meet the requirement of welding small-bore products due to large volume and structural limit in the prior art. The high temperature resistant metal inertia gas automatic welding gun mainly comprises a nozzle; a jacket is arranged outside the nozzle, and a contact tube is arranged inside the nozzle; the rear end of the nozzle is provided with an upper guide body and a lower guide body which are connected with each other; an insulation pad is arranged between the lower guide body and the nozzle; a wire feed tube is arranged in the upper guide body at the rear end of the contact tube; a gas inlet pipe is arranged in the jacket at the rear end of the upper guide body; two sides of the gas inlet pipe are provided with a water inlet pipe and a water outlet pipe; the nozzle has a hollow circular truncated cone structure; and an insulator is arranged between the jacket and the upper guide body. The high temperature resistant metal inertia gas automatic welding gun is mainly applied to common welding, and is particularly suitable for welding the small-bore products.
Description
Technical field
The utility model relates to a kind of welding gun, relates in particular to a kind of high temperature resistant fusing utmost point gas and protects automatic welding gun, and it belongs to welding technology field.
Background technology
From preceding, the MIG automatic welding gun can obtain very big weld penetration and appearance of weld attractive in appearance having under enough welding space, the cold state and can carrying out powerful welding to product.But,, be difficult to satisfy the welding of small-bore product under the high temperature because receive the restriction of welding gun version and welding gun volume.
The utility model content
The utility model is big and structural limitations to welding gun volume in the prior art, is difficult to satisfy the deficiency of small-bore product welding, provides a kind of high temperature resistant fusing utmost point gas to protect automatic welding gun.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of high temperature resistant fusing utmost point gas is protected automatic welding gun, comprises nozzle, and said nozzle outside is provided with overcoat, and inside is provided with ignition tip, and the rear end of said nozzle is provided with the last baffle and following baffle that is connected; The last baffle inside of the rear end of said ignition tip is provided with wire-feeding pipe; Be provided with air inlet pipe in the overcoat of said upward mozzle rear end, said air inlet pipe both sides are respectively equipped with water inlet pipe and outlet pipe; Said nozzle is the circular cone shape structure of hollow.
Compared with prior art, the beneficial effect of the utility model is: torch neck adopts the circular cone shape structure, and when workpiece rotated welding, the gas shield effect was more powerful, and weld seam reaches the excellent protection effect; Volume is little, can solve the deficiency of conventional larger volume welding gun, satisfies requirement of welding.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, be provided with insulator between said overcoat and the last baffle.
Further, be provided with felt pad between said baffle down and the nozzle.
