Description
Technical field
The invention belongs to the welding technique in the machinery manufacturing technology field, specifically relate to a kind of welding method for steel column type heat radiator.
Background technology
The forming process of steel column type heat radiator is first monolithic punching press, again with the involutory welding of two monolithics, then, is closing the sheet centre to the steel pipe welding fabrication.
Manual argon arc welding or carbon dioxide gas arc welding are adopted in the welding of conventional steel columnar radiators mostly, at the bottom of the welding efficiency, and the quality instability, preservative treatment is not done in radiator inside, can't form large-scale production.At present, the state-of-the-art automatic soldering technique mode that is adopted in mass industrialized production is the flash of light electric resistance welding, it be with two piece-holder in electrode, when a workpiece when a workpiece moves, two workpiece local irregularities contact points are because electric current by producing electric arc, and discharges huge heat with the fusing of workpiece contact-making surface, this moment with two workpiece rapidly to pressing, generation is without any the hot-working weld seam of cast sturcture, welding efficiency height; But also there is significant disadvantages in this welding procedure: have welding slag to splash in the welding process, all have serious overlap and welding slag inside and outside the weld metal zone; Overlap and welding slag in the workpiece outside must carry out scarfing cinder and polishing, because the radiator unique outlook, outside scarfing cinder of radiator and polishing must be adopted special plane, otherwise, be difficult to obtain good surface appearance; Inner overlap and welding slag then can't be cleared up, and the existence of these overlaps and welding slag, not only give in the steel column type heat radiator preservative treatment and bring difficulty, and will speed up the radiator inwall corrosion, and radiator is significantly reduced service life.
Summary of the invention
The objective of the invention is to adopt the welding procedure of the TIG of robot (gas tungstun arc welding) welding steel column type heat radiator, obtain than the steel column radiator that adopts the existing better quality of welding technique.On the one hand, adopt the TIG welding procedure, can eliminate overlap and welding slag that resistance flash of light welding is produced, need not to polish to obtain best inside and outside face of weld, is well positioned to meet inner chamber preservative treatment requirement.On the other hand, adopt the TIG of robot welding procedure,, can obtain very high production efficiency and stable welding quality because programme-control machine people welds.
The objective of the invention is to be achieved through the following technical solutions.
A kind of welding method for steel column type heat radiator, it comprises the following steps:
(1) with stamping forming integral heat sink device end moulding sheet and the corresponding with it middle water pipe ready for use of crossing;
(2) utilize the manipulator automatic charging, two whole termination matrix bands are put into anchor clamps platform and matched moulds respectively form whole column type radiator fin end moulding sheet;
(3) air-actuated jaw in the anchor clamps platform clamps columnar radiators sheet end moulding sheet automated exchanged cutter and can be rotated the location by the displacement platform;
(4) the multiple degrees of freedom welding robot carries out automatic TIG inert gas-shielded arc welding according to setting program to matrix band outer ring, termination and inner ring sequencing by tungsten electrode and connects;
(5) unclamp anchor clamps, utilize manipulator automatically the integral heat sink device end moulding sheet of welding fabrication to be put into saw bench, sawing machine cuts integral heat sink device end moulding sheet from the centre, become two radiator terminations;
(6) utilize manipulator automatically two radiator terminations are put back to the anchor clamps platform and add in the middle of cross and be spliced to form the monomer radiator fin behind the water pipe and clamp and the displacement platform is rotated the location by air-actuated jaw;
(7) the multiple degrees of freedom welding robot carries out automatic TIG inert gas-shielded arc welding and connects radiator termination and the middle seam that is connected of crossing water pipe according to setting program by tungsten electrode, constitutes the monomer radiator fin;
(8) a plurality of monomer radiator fins are assembled, constituted the steel column radiator.
The TIG of robot Fundamentals of Welding: robot TIG welding procedure is to utilize robot to carry out the TIG welding by special tool anchor clamps and manipulator, and the robot welding is owing to programme-control, and the automaticity height can obtain the stable quality of production and higher output.
TIG (gas tungstun arc welding connects) weldering adopts an infusible tungsten bar as arc electrodes; the blanketing with inert gas weld zone; because any chemical reaction does not take place for protective gas and motlten metal, alloying element can scaling loss in the welding process, and weldquality is very high.Protective gas can play cooling effect simultaneously, and the heat affected area width of weld seam both sides is less, and the work distortion is little, does not have in the welding process and splashes, and does not also have welding slag, so postwelding has saved the scarfing cinder workload.And for radiator do in the good application condition of anticorrosion creation, adopt this welding procedure, can satisfy not of the same race in the requirement of anticorrosive coating material, the surface of the work after the welding is bright and clean, attractive in appearance.
The technique effect that the present invention can realize is:
1. the TIG of robot welding radiator can obtain good face of weld, can eliminate overlap and welding slag that the traditional welding process is produced;
2. robot welding is owing to programme-control, and the automaticity height can obtain the stable quality of production and higher output;
3. because the steel radiator inner chamber must be done preservative treatment, play the organic coating of the isolated protection of physics for some, if the welded workpiece surface exists overlap and welding slag, can't thoroughly cover and to protect the surface, and in a single day welding slag comes off, on the lumen of radiator surface with the appearance point corrosion phenomenon, thereby quicken the corrosion of steel plate, seepage promptly appears in 2-3; Adopt the TIG of robot weldering, the surface of the work after the welding is bright and clean, attractive in appearance, can satisfy the requirement of anticorrosive coating material in the variety classes, and radiator can extend to 15-20 service life;
4. the good welding outer surface of the TIG of robot welding radiator is convenient to obtain better plastic-blasting surface;
5. because the robot manipulation has alleviated labor strength, operating personnel greatly reduce;
6. because good welding quality makes the operating pressure of radiator can reach 1.5MP.
