Abstract
The utility model relates to a special arc striking device for welding a copper bus, consisting of a bottom plate and two pressing plates, wherein the length of the pressing plate is equal to the width of the bottom plate; the bottom plate is provided with a welding pad plate; a welding seam of a workpiece is provided with welding seam pressing plates and welding seam side baffles; the pressing plates are arranged in parallel and are connected with the bottom plate by coupling bolts; arc striking plates are arranged among the two side baffles and the workpiece; and according to the width of the workpiece, wooden wedges are arranged among the side baffles and the arc striking plates so as to extrude the arc striking plates tightly. The special arc striking device has convenient construction, guarantees the surface quality of the copper bus, leads the welding seam forming to be flat, straight and smooth, and has neat edges of the welding seam, low cost, convenient operation, safe construction and high working efficiency.
Description
(1) technical field: the utility model relates to the copper busbar welding, and particularly a kind of copper busbar is welded special-purpose arc initiation device.
(2) background technology: cupric electrolysis is that copper is smelted last important step of producing, and the construction quality of the big copper busbar of electrolytic rectifier dc source is carried in conduct, is the critical process of technology controlling and process, and the copper busbar welding capacity is big, and difficulty of construction is big.Be manually directly striking welding on copper busbar in the past, and the arc crater that caused, fallen, the weld seam of copper busbar can not guarantee to put down, straight, smooth, and weld edge is irregular, and it is dangerous to construct, inefficiency.
(3) summary of the invention: the purpose of this utility model is to overcome above shortcoming, and easy construction is provided, and guarantees the copper busbar surface quality, makes appearance of weld flat, straight, smooth, and the weld seam two edges are neat shape, and cost is low, and is easy to operate, construction safety, high efficiency.Copper busbar is welded special-purpose arc initiation device, constitute by a base plate and two block pressur plates, the length of pressing plate and the width of base plate are isometric, be placed with composition backing on the base plate, be provided with weld bond pressing plate and weld bond side shield at the weld bond place of workpiece, the parallel placement of pressing plate also is connected with base plate by attachment bolt, it is characterized in that: be placed with run-on tab between two side shields and workpiece, and, between side shield and run-on tab, be placed with timber wedge jam-packed run-on tab according to the width of the workpiece.
The utility model easy construction guarantees the copper busbar surface quality, makes appearance of weld flat, straight, smooth, and weld edge is neat, and cost is low, and is easy to operate, construction safety, high efficiency.
Operating instruction of the present utility model: before the welding, adopt the DTL99-1 type and make copper busbar butt welding backing plate, copper busbar top hold-down with graphite block with electrode.Copper busbar top graphite pressing plate mainly is to keep off on welding bead groove both sides, avoids damaging the workpiece mother metal to stop electric arc, and makes appearance of weld flat, straight, smooth, and the weld seam two edges are neat.Adopt carbon arc welding technology to be fixed on the butt welding anchor clamps of this device by butt-welded copper busbar two joints, run-on tab is placed on the welding bead both sides, utilize baffle plate and timber wedge that run-on tab is fixed.At run-on tab up-igniting electric arc, and the burning certain hour treats to be connected on the welding bead behind the arc stability during welding, and swinging adds hot bead, is preheated to 450-500 ℃, presses short arc length to 20-25mm at last, and fusion root face copperwelding rod is finished welding process.
(4) description of drawings:
Fig. 1 the utility model structural representation
The 1-base plate, 2-pressing plate, 3-composition backing, 4-weld bond pressing plate, 5-weld bond side shield, 6-workpiece, 7-bolt, 8-run-on tab, 9-timber wedge.
(5) specific embodiment
Make on base plate 1 and pressing plate 2, the base plate with steel material referring to Fig. 1 and to be placed with composition backing 3, be provided with weld bond pressing plate 4 and weld bond side shield 5 at the weld bond place of workpiece 6, between two weld bond side shields 5 and workpiece 6, be placed with run-on tab 8, and according to the width of the workpiece, between side shield and run-on tab, be placed with timber wedge 9 jam-packed run-on tabs 8, pressing plate is parallel to be placed on the workpiece, is connected with base plate by attachment bolt 7 to get final product.
Claims (1)
