The technical scheme of above-mentioned anode aluminum guide group special welding machine is as follows:
It comprises a framework platform, on this framework platform, a hollow rotating shaft is housed by bearing bracket stand, front end at this hollow rotating shaft connects firmly a chuck, described friction transit joint is clamped on this chuck, in this hollow rotating shaft, a fairlead is housed by bearing, and be provided with the hold down gag of aluminum guide at the front end of this fairlead, described aluminum guide is coaxial to be put in this fairlead, and be fixed by described hold down gag, the tail end of described hollow rotating shaft links by transmission mechanism and a motor, the place ahead at described framework platform, position corresponding to chuck is provided with one by hydraulic-driven, and steel pawl installing rack in axial sliding, described steel pawl is fixed on this steel pawl installing rack, at the afterbody of this framework platform, tail end corresponding to fairlead is provided with one by hydraulic-driven, and aluminum guide jacking block in axial sliding.
By technique scheme as can be seen, two abrasive end faces of described friction transit joint respectively are provided with a cone boss, insert respectively during work in the depression of described steel pawl and aluminum guide welding end surface, make the existing radial friction of friction process that axial rub also be arranged, reach the effect of the real weldering in periphery and center, that is to say, make the welding end surface of friction transit joint and steel pawl and aluminum guide all reach real weldering, increased the water conservancy diversion area of anode aluminum guide group to greatest extent, thereby reduce the groove pressure drop of electrolytic cell, reduce energy consumption, finally reached object of energy saving.Experiment shows: the present invention compares with existing anode aluminum guide group, can reduce more than the groove pressure drop 40mv, and ton aluminium power consumption is saved more than 137 degree.
Description of drawings
Accompanying drawing, structure cutaway view of the present invention.
The specific embodiment
Referring to accompanying drawing, described anode aluminum guide group comprises a steel pawl 1 and an aluminum guide 5, steel pawl 1 and and aluminum guide 5 between be provided with a friction transit joint 2, described friction transit joint 2 has a flat steel basal disc, on two abrasive end faces of this steel basal disc, be respectively equipped with a cone boss, on the welding end surface of steel pawl and aluminum guide, be respectively equipped with and the accurate depression that cooperates of this cone boss, described accurate the cooperation is meant that depression is more smaller than boss, spin friction by friction transit joint 2 welds together described cone boss and the complete tight fit of described depression.
Again referring to accompanying drawing, in order to realize the friction welding of above-mentioned anode aluminum guide group, its special-purpose friction-welding machine comprises a framework platform 0, on this framework platform, a hollow rotating shaft 4 is housed by bearing bracket stand 9, front end face at this hollow rotating shaft connects firmly a chuck 3, it can be rotated with hollow rotating shaft 4, described friction transit joint 2 is held on this chuck 3, in hollow rotating shaft, a fairlead 12 is housed by bearing 13 is also coaxial, the cross section of this fairlead is square, be provided with the hold down gag of aluminum guide 5 in the front portion of fairlead, this hold down gag is made of a plurality of hydraulic pressure depression bars 10 of circumferentially evenly arranging, and described aluminum guide 5 is put in this fairlead 12, if the diameter of aluminum guide 5 is crossed the internal diameter less than fairlead 12, can add backing plate 6, thereby make aluminum guide 5 coaxial with fairlead 12; Tail end at this hollow rotating shaft is provided with a driving-disc 11, and this driving-disc 11 joins by belt gear and a motor, and is rotated by motor-driven hollow rotating shaft 4; In the place ahead of described framework platform 0, be provided with a steel pawl installing rack 7 corresponding to the position of chuck 3, described steel pawl 1 is fixed on this installing rack, the welding position that makes steel pawl 1 is just facing to friction transit joint 2, this installing rack 7 is installed on the shifting sledge, and by its endwisely slipping along rotating shaft 4 of hydraulic-driven; At the afterbody of this framework platform 0, be provided with the jacking block 8 of an aluminum guide 5 corresponding to the tail end of fairlead, this jacking block also is installed on the shifting sledge, also is by its endwisely slipping along rotating shaft 4 of hydraulic-driven.
