Abstract
The invention discloses a method for welding large-area zinc electrolysis cathode plates. The method is characterized in that a stir friction welding technology is applied to a process for welding and manufacturing cathode plates, aluminum beams, conductive heads and aluminum plates with structures and dimensional tolerance which meet requirements of the stirring friction welding process are developed, and process steps and parameters which meet welding requirements are determined. The method has the advantages that the stir friction welding technology is applied to welding the cathode plates for the first time, the stir friction welding process is free of electric arc or splashing or slag inclusion or smoke or filler wires or beveling or the like, a welding procedure is clean, environment-friendly and efficient, weld joints are good in weld penetration, conductivity and corrosion resistance and high in welding strength, surfaces of the weld joints are smooth and flat, and the like.
Description
Technical field
The invention belongs to Zinc electrolysis negative plate welding method technical field.
Background technology
The minus plate welding comprises two parts: the welding of the welding of aluminium beam and conductive head, aluminium beam and aluminium sheet.At present, generally adopt both at home and abroad mode such as argon arc welding to realize the welding processing of minus plate, Shang Weijian is applied to stirring friction-welding technique any report of electrolytic zinc minus plate production preparation.Facts have proved that argon arc welding technique can satisfy the production of electrolytic zinc minus plate.But welding process produces high strength arc light and high-temperature flue gas, easily operating personnel is produced occupational hazards.And because aluminium beam and conductive head are thicker, the argon arc welding can't be welded thoroughly, directly influences the minus plate electric conductivity, and the turn-over welding causes welding efficiency low.
Summary of the invention
A kind of large tracts of land Zinc electrolysis negative plate welding method, the present invention is characterised in that: the agitating friction solder technology is applied on the welding preparation technology of negative electrode stereotype; According to the feature of stirring technique, developed the novel aluminum beam of suitable stirring welding procedure.The welding step and the technological parameter that satisfy the minus plate welding have been determined.The present invention adopts the welding of the minus plate of agitating friction technology realization, has solved the defective that conventional oxygen-torchman plants and exists, and has cleaning, environmental protection, characteristics of high efficiency.
Advantage of the present invention and good effect are:
This welding technique has no arc light, do not have and to splash, no slag inclusion, no flue gas, not have silk filling, need not bevel, need not characteristics such as protection-gas welding, and whole process environment-protecting clean has significant advantage for raising occupational health level.Be specially:
(1) cleaning
This new welding process has no arc light, do not have and to splash, no slag inclusion, no flue gas, not have and fill silk, need not bevel, need not characteristics such as protection-gas welding, and whole process cleans, environmental protection, has significant advantage for raising occupational health level.
(2) efficient
The cathode aluminum plate of this process about can disposable through welding 7mm need not turn-over, and the welding efficiency height is fit to mass production.
(3) good product quality
This process through welding is good, and face of weld is smooth smooth, can improve the resistance to corrosion of weld seam tolerance zinc electrolyte, significantly improves the service life of minus plate.Secondly, this technology weld strength height, conductance are good, are applied to the industry of zinc electrolysis for production, and energy conservation and consumption reduction effects is remarkable, can reduce production costs.
Below in conjunction with the drawings and specific embodiments the present invention is done further explanation.

The specific embodiment
A kind of large tracts of land Zinc electrolysis negative plate welding method, the present invention is characterised in that: the agitating friction solder technology is applied on the welding preparation technology of negative electrode stereotype; According to the feature of stirring technique, developed the novel aluminum beam 1 of suitable stirring welding procedure; The welding step and the technological parameter that satisfy the minus plate welding have been determined.The present invention adopts the welding of the minus plate of agitating friction technology realization, has solved the defective that conventional oxygen-torchman plants and exists, and has cleaning, environmental protection, characteristics of high efficiency.The welding schematic diagram as shown in Figure 1.
1) prepares the aluminium beam of new structure
2) welding step and technology
(a) welding step: the present invention adopts three welding posts to finish the welding procedure of minus plate: a station welding of aluminum beam 1 and conductive head 3 first, two station welding of aluminum beams 1 and 3 second of conductive heads, three station welding of aluminum beams 1 and aluminium sheets 2.
(b) welding procedure
Throat thickness: throat thickness is respectively 13-13.5mm, 13-13.5mm, 6.6-6.9mm.Carry out turn-over after the welding of one station is finished, carry out the welding of two stations again, guarantee the equal through welding of all weld seams.
Play solder joint 6 and whole solder joint 7 positions: stir in the welding process, will have pin-holing inevitably, for guaranteeing the intensity of aluminium beam 1, the fusion length of conductive head 3 and aluminium beam 1 surpasses the length of conductive head.
3. welding parameter
According to technology characteristics, through repetition test, determine the key process parameter that minus plate stirs welding.
1) one, two stations: the shoulder amount of being pressed into of mixing needle is 0.8-1.3mm, mixing needle penetrates the degree of depth less than aluminium sheet 2 thickness 0.8-1.3mm, the speed of mainshaft is 1200-1500r/min, main shaft Z-direction feed speed 25-45mm/min, Y-direction feed speed 320-450mm/min.
2) three stations: the amount of being pressed into of mixing needle shoulder be 0.8-1.1mm, mixing needle to penetrate the degree of depth be 1200-1500r/min, main shaft Z-direction feed speed 20-50mm/min less than aluminium sheet 2 thickness 0.8-1.1mm, the speed of mainshaft, Y-direction feed speed 650-800mm/min.
3) by milling the material cutter head in stirring-head design, stirring-head is rotated shoulder roll plumbous bits and mill, obtain smooth smooth welding plane.Two weldment weld seam end faces do not have scraper, do not have the band material when guaranteeing welding.
