Accompanying drawing explanation
The above and other feature of the present utility model, character and advantage become more obvious by passing through below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the sectional view that in the utility model one embodiment, electric arc plane cuts bar.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth more details in the following description so that fully understand the utility model; but the utility model obviously can be implemented with multiple this alternate manner described that is different from; those skilled in the art when doing similar popularization, deduction without prejudice to when the utility model intension according to practical situations, therefore can should not limit protection domain of the present utility model with the content of this specific embodiment.
In Fig. 1, core wire 2 is not shown by the mode of filling hatching, but be so more easily well understood to the structure that electric arc plane cuts bar, in the embodiment shown in fig. 1, electric arc plane cuts bar and comprises core wire 2 and coating 1, the right-hand member of core wire 2 is bare terminal end 22, outside exposed, can be clamped by the clamping device of bonding machine.Namely the end of core wire 2 is arranged in figure left end for generation of that one end of electric arc.Core wire 2 has the gas access 23 of the side being positioned at bare terminal end 22 and extends to the gas passage 21 of end of core wire 2 from gas access 23 along the center of core wire 2.Except gas access 23, gas passage 21, core wire 2 is the same with standard core wire, comprises its appearance and size, material, and such as its material can be mild steel, and its diameter is 3mm, but is not limited thereto, also can be different from standard core wire.The material of coating 1 also can adopt existing material, utilizes physical reaction producing heat to accelerate metal molten, improves the stability of arc burning, and the strong air flow that gas-forming agent is released is the source of the gas blowing down deposite metal.
The shape of gas access 23 can be circular or other shapes, the transverse shape of gas passage 21 also can be circular or arbitrary shape, even the smoothness of the inner wall surface of gas passage 21 also need not have too high requirement, can by casting or other manufacture technics.
Although do not illustrate bonding machine and compression gas suppling device in figure, but be understandable that, electric arc plane as shown in Figure 1 cuts bar and is arranged on as welding rod in the past on bonding machine, bonding machine can be exchange or direct current bonding machine, its arc voltage is probably 45-57 volt, and it is probably 150-200 peace times that plane cuts electric current.Compression gas suppling device is sealably coupled to gas access 23 by gas piping, operationally, electric arc plane cuts bar along soldering turret longitudinally clamping, after lighting electric arc, Compressed Gas is introduced by gas passage 21, the coating 1 that plane cuts bar continue, strongly spray during arc burning in the gas of design flow, the amount of gas pressure of Compressed Gas is the bigger the better within the specific limits, is limited not blow power-off arc.Compressed Gas can be compressed air or argon gas or other gas.
Electric arc plane as shown in Figure 1 cuts bar and can design, manufacture according to the profile of standard, and its plane power of cutting is improved, in an experiment of utility model people, cutting bar for the diameter plane of electric arc as shown in Figure 1 that is 3mm can shearing thickness be the general steel plate of 30mm thickness, moreover, the amount that the electric arc plane of burning cuts bar decreases, and namely plane cuts efficiency and is also improved.
Electric arc plane in Fig. 1 cuts bar and introduces Compressed Gas by increasing gas passage 21, strengthen the blowing force of electric arc, reach efficient plane to cut, raise labour productivity, avoiding producing plane, to cut power little, slag is residual to be blown down only, affects later stage welding quality, the defects such as the disadvantages affect operating efficiency that the scope of application is limited.The electric arc plane of Fig. 1 cuts bar to be had common planning and cuts the same using function of bar, and same hand plane cuts mode of operation, same flexible operation, easy to use.Owing to machined gas passage 21, increase plane and cut blowing force, operating efficiency is significantly improved, shortens the activity duration, certain electric energy and welding material can be saved.Its scope of application comprises and is not only not limited to aftermentioned situation.
1, the welding bevels such as cast iron are applicable to.When cast iron welding, often need bevel, namely cut open groove or to the processing of workpiece bevel at surface of the work plane, if use common planning to cut bar bevel, due to plane, to cut blowing force little, and often dig the groove cut open out more shallow, the fusion penetration of welding is also more shallow, and intensity is not high.Machined gas passage because the utility model plane cuts bar, increase plane and cut blowing force, make bevel easier, efficiency is higher, and quality significantly improves.Its advantage has:
(1), because core wire machined gas passage, dig gas when cutting operation and create larger blowing force, production efficiency significantly improves;
(2), once can dig the degree of depth of cutting to significantly improve, for should not hot-working cast iron materials repeatedly, can avoid, because plane cuts shallow and hot-working repeatedly, avoiding producing new defect;
(3), because gas blowing force is large, the slag that plane cuts generation blows down clean, and the work that oxide layer is removed in follow-up welding reprocessing polishing obviously reduces even to be avoided, and improves welding quality;
(4), dig and cut blowing force increase, operate more convenient;
(5), the plane raising of cutting efficiency also makes cast iron heated time reduce, the groove place Quality advance after processing, thus avoids the generation of HOT CRACK FOR WELDING P and cold crack.
2, the plane be applicable to when engineering structure is installed or transformed cuts.When engineering structure is installed or transform, often need to carry out various cutting to workpiece.Because this plane cuts bar blowing force greatly, efficiency is high, very applicable this condition of work, and it has the advantages that oxygen-acetylene cuts or plasma cut does not have:
(1), only need an electric welding machine, a tracheae, equipment is simple, multi-functional, can weld also can dig and cut, avoid use large number quipments;
(2), the cutting of relative oxygen acetylene and plasma cut, it is flexibly small and exquisite that this plane cuts bar, can multi-angle, all positon plane cut, applicable various complex environment;
(3) can dig in water and cut, such as water pipe plane cuts off disconnected, perforate etc.New planing cuts bar and can play a significant role at industry fields such as machine-building, construction and installation, maintenances of equipment according to its feature.
