Description

A kind of environmentally friendly integral type craft MAG welding guns

Technical field

The utility model is related to technical field of welding equipment, especially a kind of environmentally friendly integral type craft MAG welding guns.

Background technology

Weld fumes be by wlding end and mother metal melted under high-temperature electric arc after form steam, shape after oxidized and condensation Into solia particle, alveolar can be entered by human upper airway, be deposited on lung and cause breathing problem, pneumoconiosis, lung cancer etc..Mesh It is preceding to based on gravity-flow ventilation, being aided with the traditional means such as Wind Volume local exhaust more than weld fumes, to improve the work at electric welding workshop Industry environment.Such method is influenceed greatly by natural climate, and local exhaust facility noise, power consumption are big etc., and weld fumes is flown away in work Between in environment, the healthy of weld job personnel is deeply hurt, and atmosphere pollution is not administered effectively.Present manufacturer Problem above is noticed, also begins to research and develop environment-friendly smoking welding gun, environment-friendly smoking welding gun is functionally absorbed than the common welding gun more The function of cigarette is welded, it will weld cigarette by the suction nozzle on welding gun head and the suction pipe at rear portion, using high vacuum negative pressure and is drawn onto purification dress Put.

The environment-friendly smoking welding gun of prior art is only simply transformed common welding gun, using inlay card pattern, outside cable A parallel smoking pipeline, had both increased welding gun weight again, and the pulling of multichannel pipeline is awkward, and welding feel is bad, also has an impact weldering The defects such as sight are connect, the popularization and utilization of environmentally friendly welding gun is greatly limit, fail to play green, the environment protecting, smoke abatement of anticipation Dirt effect is poor.

Utility model content

The purpose of this utility model is a kind of environmentally friendly integral type craft MAG welding guns designed for prior art deficiency, It is real using the handle that cable assembly and threeway tail joint integrative-structure and spherojoint and bellows connection are set in smoking hose Existing light and flexible is easy to operate and meets operator's use habit, while conventional manual MAG welding performances are ensured, moreover it is possible to effectively Weld fumes is drawn, the health and safety of operator have been ensured, and can be replaced according to different welding post and welding manner, selection The range hood of the environment-friendly smoking welding gun front end of different size, or position of the adjustment range hood on rifle neck are changed, weldering is not being destroyed On the premise of the carbon-dioxide protecting gas blanket of rifle, set range hood inlet scoop apart from the optimal recommended location of pad, both may be used Ensure the quality of welded seam, effective air draught dust removing effects can be obtained again, simple in construction, easy to use, reliability is high, safety Property it is good, green and healthy energy-conservation.

What the purpose of this utility model was realized in：A kind of environmentally friendly integral type craft MAG welding guns, including it is total by rifle neck Into, handle, smoking hose, cable assembly and afterbody three-way connection composition smoking welding gun, be characterized in that rifle neck assembly is provided with The range hood being connected with smoking bellows, smoking bellows links into an integrated entity with handle, smoking hose and afterbody three-way connection, institute State handle and be provided with the switch being connected with cable assembly；The cable assembly includes the CO being arranged in smoking hose₂Appendix With control cable；Described smoking hose one end is connected by the spherical cavity formula collar of spherojoint and handle tail end, and the other end is by locking Tight nut is fixedly connected with afterbody three-way connection.

The utility model is easy to use compared with prior art with simple in construction, and reliability is high, and security is good, green, Environmental protection, energy-conservation, can be selected to replace the environment-friendly smoking welding gun front end of different size according to different welding post and welding manner Range hood, or position of the adjustment range hood on rifle neck, on the premise of the carbon-dioxide protecting gas blanket of welding gun is not destroyed, Set range hood inlet scoop apart from the optimal recommended location of pad, can both ensure the quality of welded seam, can obtain again effectively Air draught dust removing effects.
