Description
Technical field
The utility model relates to metal processing, and a kind of thin plate becomes the automatic welding device of 90 ° of angle welding with thin plate.
Background technology
At present, the heat exchanger fin of plate sheet welding has become the main heat exchange element that is used for heat exchange on the plate type heat exchanger.Existing automatic welding device does not have the equipment of thin plate right angle welding usefulness.The problem that need to solve is with behind 2 thicknesss of slab thin plate folding that is 1.2mm, and flanging end face and 90 ° of angles, flanging thin plate edge not are welded to each other, and forms one group of cuboid heat exchanger fin in the heat exchanger that passage is crossed as 90 ° each other.Thin plate itself was heated because of limit portion and very easily produces wave transformation when technological difficulties were welding.The flanging height is merely 12mm, so the flanging space is little, Gu the clamping difficulty is big.And become 90 ° of angles when guaranteeing thin plate flanging one side and flanging one side is not to be welded relatively, guarantee the complete applying in both sides to be welded.When if two right-angle sides are relative, certain some contact is bad, lack of penetration, incomplete fusion defective can occur, and quality can not guarantee, causes waste product.After welding is accomplished, also to guarantee the flatness and the perpendicularity of every thin plate.So difficulty of processing is very big, traditional manual welding that does not add anchor clamps can not meet the demands, and production efficiency is low.
Summary of the invention
The purpose of the utility model provides a kind of thin plate angle welding automatic welding device, and assurance lamella thickness 1.2mm and both sides flanging height only 90 ° of angles of 12mm weld automatically, satisfy the quality requirement of postwelding thin plate flatness and perpendicularity and heat exchanger.
This thin plate angle welding automatic welding device; Be used for weld seam and be positioned at the parallel weld job that thin plate flanging end and thin plate edge become 90 ° of angles; Comprise two kinds of structures, it is characterized in that leg length edge equipment structure one: base plate is fixed on the support level face, and slide rail, slide block are installed on the base plate; Connect governor motion on the slide block, the welding gun that the governor motion inclined-plane is installed becomes 30 ° of gradient contacts wire with the weldment heat exchanger fin of weldment combination by-level face; The weldment thin plate places between base plate, the liner plate, on liner plate, puts a thin plate again, presses pressing plate at last, supports the space to be welded of weldment heat exchanger fin, by nut base plate and pressing plate two long ends are clamped, and by lining-plate bolt crosswise fixed weldment; Through pad chucking liner plate, heat exchanger fin flanging and base plate, vertically fixing heat exchanger fin prevents the vertical wave transformation of heat exchanger fin by bed bolt; Motor driven gear fixing on base plate drags slide block, 90 ° of welded corner joints to be welded that the welding gun on the governor motion is made up along weldment, and argon-arc welding gun is accomplished whole weld job automatically under the drive of conveyer belt; The structure two that welding angular width limit is used with structure one difference that welding angular length limit is used is: the angular width side weld connects with A-frame and separates with the weldment base, and A-frame flash and housing facade are fixed, and increases a backing plate.
The design's thin plate angle welding automatic welding device; It is yielding to have solved in the prior art plate sheet welding effectively, and space to be welded is little, and the clamping difficulty is big; The ropy technical barrier of weld appearance can satisfy the requirement of weld strength, presentation quality, thin plate flatness and perpendicularity.Have reasonable in design, loading and unloading easily, easy to operate, appearance of weld is good, saves time, laborsaving, labour intensity is low, the characteristics that welding efficiency is high.Through repetition test, reliability is high, welding efficiency is high.
