Abstract
The utility model discloses an argon filling tool for welding training. The tool comprises a tube base and a plug, wherein the tube base is in a round tube shape, one end of the tube base is sealed, a boss is arranged outside the opening at the other end, a fixing sheath piece is arranged on the outer side of the boss, a fixing nut is arranged on the outer side wall of the tube base and connected with a bolt, one end of the bolt penetrates through the fixing sheath piece, a to-be-welded round-tube-shaped workpiece arranged on the boss is fixed by the bolt and the fixing sheath piece, an air inlet hole is formed in the side wall of the tube base, one end of another to-be-welded tube-shaped butt-joint workpiece is butt-jointed with a tube-shaped butt-joint workpiece fixed on the tube base, the plug is arranged at the other end, and an air outlet hole is formed in the plug. The tool is simple and reasonable in structure, so that weld metal in workpieces can be fully protected, the production of smog and harmful gases are effectively prevented effectively, and the tool can be reused.
Description
Technical field
The utility model relates to a kind of argon arc welding training frock, specifically a kind of welding training argon filling frock.
Background technology
Along with the stable development fast of China's economy, demand to electric energy constantly increases, expect the year two thousand twenty whole nation installed capacity and will reach 1,000,000,000 kilowatts, wherein thermoelectricity installed capacity will account for more than 70%, and Development of Ultra-Supercritical unit will be the inexorable trend that cost of electricity-generating was raised the efficiency, saved the energy, improves environment, reduces in China's thermal power generation.The trend of thermal power generating technology development is to improve the parameter of steam to improve thermal power plant efficiency, along with the raising of vapor (steam) temperature and pressure, researches and develops and used large quantities of New Heat-Resistant Steel both at home and abroad.At present, T/P92 steel, super stainless steel high temperature thermostrength in this type of steel grade is the highest, in supercritical unit high-temperature surface and live steam piping, obtain extensive application, for this reason, also just proposed corresponding requirement for the professional skill training of this type of high pressure welding personnel.
In T/P92 steel, this type of steel grade welding training of super stainless steel; in atmosphere, can cause a large amount of alloying component scaling loss and oxidation if prime coat sealing run is directly exposed in welding process; make weld seam lose the combination property such as machinery, chemistry, must make air chamber enforcement argon-filled protection to its sealing run so weld this type of steel grade.In the past, the material of making protection air chamber adopted the low melting point such as the water soluble paper, adhesive tape combustible material more, in welding process, certainly will produce a large amount of smog and pernicious gas, had destroyed greatly working environment.And these combustible material costs are higher, and cannot again utilize after burning, cause larger waste.Therefore, design is a kind of reusable, avoids the argon-filling device that produces smog and pernicious gas to become the current technical issues that need to address.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to solve the problems of the technologies described above, and internal weld seams metal coating effect is abundant, and can avoid producing smog and pernicious gas, reusable welding training argon filling frock.
The technical solution adopted in the utility model is: a kind of welding training argon filling frock, include base and plug, described base is set to tubular, described base one end closure, the other end mouth of pipe is outside equipped with boss, described boss arranged outside has fixing sheath sheet, on described base lateral wall, be provided with hold-down nut, described nut connecting bolt, described bolt end is through fixing sheath sheet, described bolt and fixing sheath sheet are fixed the tubular workpiece to be welded being arranged on boss, on the sidewall of described base, be provided with air admission hole, dock with the tubular workpiece being fixed on base another part tubulose docking to be welded workpiece one end, the other end is provided with plug, on described plug, be provided with venthole.
Further, described frock adopts heat resisting steel to make.
The utility model frock adopts heat resisting steel to be made, and the high temperature producing can resist welding time ensures indeformable, the not burning of entirety;
Highly versatile, can support the use for multiple grade of steel metal tube;
Quality is little, easy for installation, and can accomplish to reuse;
Can realize that test specimen group is solid to, point, weldedization.Group to time, only need be by workpiece as for being grouping, putting solid, welding on device base;
There is the exclusive design of welding for different tube diameters test specimen, designed fixing sheath sheet and bolt, by bolt and fixing sheath sheet, test specimen and base are firmly fixed, thereby improved purity of argon in air chamber, ensured argon filling effect;
Air chamber volume is little, has greatly saved argon gas use amount, has reduced training cost.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model;
It shown in Fig. 2, is base structural representation of the present utility model.
Detailed description of the invention
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise base 1 and plug 2, described base 1 is set to tubular, described base 1 one end closures, the other end mouth of pipe is outside equipped with boss 3, described boss 3 arranged outside have fixing sheath sheet 4, on described base 1 lateral wall, be provided with hold-down nut 5, described nut connecting bolt 6, described bolt 6 ends are through fixing sheath sheet 4, described bolt 6 and fixing sheath sheet 4 are fixed the tubular workpiece to be welded being arranged on boss 3, on the sidewall of described base 1, be provided with air admission hole, dock with the tubular workpiece being fixed on base another part tubulose docking to be welded workpiece one end, the other end is provided with plug 2, on described plug 2, be provided with venthole, described frock adopts heat resisting steel to make.
When the utility model uses, a tubular workpiece to be welded is positioned on the boss 3 of base 1, use bolt 6 to be fixed firmly, use welding clamp to clamp tubulose docking workpiece to be welded another part, one end is used plug 2 to seal, and the other end makes it dock with the tubular workpiece to be welded being fixed on base 1, then be filled with argon gas by the air inlet being arranged on base 1, weld, after having welded, workpiece is unloaded, practise next time.
The utlity model has simple and reasonable for structurely, internal weld seams metal coating effect is abundant, and can avoid producing smog and pernicious gas, reusable feature.
