Abstract
The utility model relates to a universal gun barrel for a carbon dioxide arc welding gun, which is composed of a stainless steel hose, an outer layer rubber hot shrinkable sleeve, an inner layer copper spring and a tail part copper pipe. The universal gun barrel for the carbon dioxide arc welding gun has the advantages of simple structure, freedom in universal bending, and comfort and convenience in use, saves materials and improves efficiency.
Description
Technical field
The utility model relates to a kind of welding gun gun barrel, is specifically related to a kind of universal gun barrel of carbon-dioxide arc welding welding gun.
Background technology
Welding gun in carbon-dioxide arc welding all is made up of the gun barrel of nozzle, ignition tip, ignition tip seat, insulation sleeve and stationary curved angle basically at present, and the gun barrel of stationary curved angle is made up of the copper pipe and the outer layer rubber thermal shrinkable sleeve of stationary curved angle.
Because the gun barrel angle of bend is fixed, the welding of a lot of corners and depths must allow the health of workman's bending, distortion oneself show various postures of feeling bad and finish, even even so also has some places to be difficult to finish welding.So big labor strength of welding difficulty is very big, and production efficiency is lower.And welding quality is difficult to guarantee.
Because gun barrel is the copper pipe of an integral body, must scrap whole gun barrel, waste material, cost height after service time is long.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provide a kind of simple in structure, can free universal bending, save the gun barrel of cost, comfortable, the carbon-dioxide arc welding welding gun of enhancing productivity easy to use.
The purpose of this utility model is achieved through the following technical solutions: a kind of universal gun barrel of carbon-dioxide arc welding welding gun; form by stainless steel flexible hose, outer layer rubber thermal shrinkable sleeve, internal layer copper spring and afterbody copper pipe; the rubber thermal shrinkable sleeve has tightly been overlapped in the outside of described stainless steel flexible hose; the stainless steel flexible hose the inside is with the internal layer copper spring; the sealed at both ends two ends that are connected the internal layer copper spring of stainless steel flexible hose, the afterbody copper pipe is by being threaded in internal layer copper spring afterbody.
Further improvement of the utility model is: the universal gun barrel of described carbon-dioxide arc welding welding gun, its internal layer copper spring are to be reeled by copper bar to form, and the thickness of copper bar is 1.5 millimeters-4 millimeters.
Further improvement of the utility model is: the universal gun barrel of described carbon-dioxide arc welding welding gun, the internal diameter of its internal layer copper spring are 4 millimeters-10 millimeters.
Further improvement of the utility model is: the universal gun barrel of described carbon-dioxide arc welding welding gun, its stainless steel soft bore is bigger 0.2 millimeter-1.0 millimeters than the external diameter of internal layer copper spring.
The utility model compared with prior art has the following advantages:
1, the utility model adopt can free universal bending structure, the former welding job that is difficult to weld of a lot of corners and depths is finished fast by workman's Energy and comfort ground, greatly reduce labour intensity, obviously improved production efficiency and quality.
2, the utility model afterbody adopts dismountable being threaded, and when the part of this universal gun barrel was scrapped, detachable remainder had been saved material, has reduced waste.
Description of drawings
Accompanying drawing cuts open schematic diagram for the structure of this face utility model;
Number in the figure: 1-outer layer rubber thermal shrinkable sleeve, 2-stainless steel flexible hose, 3-internal layer copper spring, 4-afterbody copper pipe.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Accompanying drawing shows a kind of embodiment of the present utility model, comprises stainless steel flexible hose 2, outer layer rubber thermal shrinkable sleeve 1, internal layer copper spring 3 and afterbody copper pipe 4.Outer layer rubber thermal shrinkable sleeve 1 tightly is enclosed within on the stainless steel flexible hose 2, and stainless steel flexible hose 2 two ends are welded on the two ends of internal layer copper spring 3.All process external screw thread on 3 liang of external parts of internal layer copper spring, front end links to each other with the ignition tip seat, and tail end links to each other with afterbody copper pipe 4.The screw thread at internal layer copper spring 3 two ends is earlier the welding of copper spring bar two ends to be linked to be copper pipe, goes out screw thread in its Surface Machining then, also can be welded to internal layer copper spring 3 two ends with the short copper pipe that processes screw thread.Internal layer copper spring 3 adopts the copper bar of 2 millimeters thick, 7.5 mm wides to reel and forms, and this moment, internal diameter was 8 millimeters, and external diameter is 12 millimeters, to be applicable to the welding gun of 300 Ampere currents specifications.Stainless steel flexible hose 2 internal diameters are that 12.5 mm lengths are 90 millimeters.
Internal layer copper spring 3 can also adopt the copper bar of 2 millimeters thick, 12.5 mm wides to reel and form, to adapt to the welding gun of 500 Ampere currents specifications.
Stainless steel flexible hose 2 internal diameters are with the variation respective change of internal layer copper spring 3 specifications and external diameter.The length of stainless steel flexible hose 2 and internal layer copper spring 3 changes with producing actual needs.
Stainless steel flexible hose 2 is except the bellows form, also available other as forms of implementation such as spiral coiled pipes.
