Description
Technical field
The utility model relates to the soldering appliance field, more particularly, relates to a kind of submerged-arc welding run-on tab.
Background technology
It is more and more to be welded on Industrial Application now, and especially submerged-arc welding, submerged-arc welding are one of higher mechanization welding methods of current production efficiency, and its full name is Lincoln weld, claims automatic arc welding under the welding flux layer again.Because production efficiency is high, weldquality and the good reason of working condition, submerged-arc welding especially plays an increasingly important role in the welding of the straight weld of H shaped steel and steel pipe in the welding of large-scale workpiece.Usually in order to obtain the section of weld joint of normal size at welding point top, to assemble a metallic plate before the weldering when submerged-arc welding is welded in the factory.Before the welding earlier with a sheet material by hand arc welding spot weld an end of the welded seam of wanting, submerged-arc welding is to begin striking from this piece plate then, when waiting electric arc to move to the weld seam of required processing; Electric current, voltage and the electric arc of welding are all more stable; The weldquality of this moment welding is relatively good, and defective is few, wait welding to accomplish after; This plate is sliced off, this piece plate is run-on tab again.
Existing run-on tab is the special steel plate of factory's the inside well cutting, will do discarded the processing after run-on tab is used once.Aborning, after a steel pipe or steel plate welding completion, must the run-on tab that be welded on steel pipe or the steel plate be cut down; This procedure all is to be cut with hand-held acetylene burning torch by manual work at present, owing to be manually-operated, otch is difficult to guarantee neat level and smooth; Will pass through the processing of polishing or tack then and just can carry out next process, run-on tab is installed and the cutting trouble, and production efficiency is low; And used once and just throw away, increased material consumption, caused the very big wasting of resources.
Existing technological improvement all was how aspect the cutting arc-striking plate, like Chinese patent numbers 200820190741.0, open day on 06 17th, 2009; Disclose the patent of a kind of welded still pipe run-on tab and blow-out plate cutter sweep, related to the welded still pipe run-on tab and the blow-out plate cutter sweep of cutting machine, it is on column, to be provided with a cantilever; The locator assembly is arranged on the cantilever; Afterbody is provided with a balance weight body that balances each other with support, cutting dolly assembly, magnechuck assembly, arc track gross weight, and the locator assembly is arranged on the cantilever, and there is support on the top; Respectively there is a magnechuck assembly at the two ends of support; Arc track has cutting dolly assembly on the arc track between two magnechuck assemblies, on the cutting dolly assembly cutting gun is arranged.During work; The magnechuck assembly of this utility model is placed on the outside of steel pipe; Run-on tab or the blow-out plate of plasma cutting gun being aimed at steel pipe can cut, and this utility model has replaced artificial hand-held acetylene burning torch cutting, and its otch is neatly level and smooth; Can not only save a large amount of steel and rubber seal, and improve operating efficiency.But this patent is just more convenient when the cutting arc-striking plate also just improving the cutting arc-striking plate, but run-on tab also will connect through manual electric arc welding when installing, and run-on tab was done waste treatment after welding was accomplished, and caused the wasting of resources.
Summary of the invention
The technical problem that solves
The purpose of the utility model is to overcome in the existing submerged-arc welding solder technology, welds large-scale weld seam and will use run-on tab, and troublesome poeration, and the problem of waste material provide a kind of submerged-arc welding run-on tab, and this arc plate is easy to use, need not be welded on the mother metal in advance.
Technical scheme
The purpose of the utility model is achieved through following technical scheme:
A kind of submerged-arc welding run-on tab comprises rotor plate, also comprises spring, base and hinge, and described rotor plate from left to right is followed successively by striking section, first tilting section, pedal section and second tilting section, and the upper surface of striking section and pedal section is a horizontal plane; The right-hand member of second tilting section links to each other with base through spring on the said rotor plate, and the left end of second tilting section of rotor plate links to each other with base through hinge.Rotor plate can be that the center rotates around base with the hinge.During use, electric arc ignites from the striking section, and the pedal section is for making things convenient for the workman to trample; After electric arc ignited, when electric arc progressively moved on the weld seam of steel pipe or welding base metal of required welding, electric current and voltage were also stable; This moment, when stepping on down the pedal section, connecting rod can be that rotate at the center with the base through hinge the striking section contacts local molten bath ot-yet-hardened with mother metal when; The striking section descends, and separates with mother metal, and electric arc continues welding base metal.
Two upper surfaces of said striking section and pedal section parallel.
Said first tilting section is parallel with the upper surface of second tilting section, and angle between striking section and first tilting section and pedal section equate with angle between second tilting section.
Beneficial effect
The utility model compared with prior art has following advantage:
(1) the utility model not only comprises rotor plate, also comprises spring, base and hinge, and rotor plate from left to right is divided into striking section, first tilting section, pedal section and second tilting section successively again, and the upper surface of striking section and pedal section is a horizontal plane; The right-hand member of second tilting section links to each other with base through spring on the said rotor plate, and the left end of second tilting section of rotor plate links to each other with base through hinge, and rotor plate can be that the center rotates around base with the hinge; During welding, when the striking section contacts local molten bath ot-yet-hardened with mother metal, when stepping on down the pedal section; Rotor plate can be that rotate at the center with the base through hinge, and the striking section reduces, and separates with mother metal; Electric arc continues welding base metal, before the welding without the fixing run-on tab of manual electric arc welding, after the welding also without the cutting arc-striking plate; Easy to operate, time saving and energy saving;
(2) the utility model can repeatedly use as run-on tab, economical with materials;
