Arc extended surface tube full-automatic welding machine
Technical field
The invention belongs to full-automatic welding machine, be specifically related to a kind of arc extended surface tube full-automatic welding machine.
Background technology
Extended surface tube automatic welder(welding machine) guidance quality is poor at present, and structure is compact not, and not prison welding is solid, and fin easily comes off, and welding quality and production efficiency are undesirable.
Summary of the invention
The above-mentioned defect existing in order to overcome prior art field, the object of the invention is to, a kind of arc extended surface tube full-automatic welding machine is provided, compact conformation, easy to operate, control accurately, production efficiency is high, firm welding, fin difficult drop-off, welding quality stable, welding quality is good, automaticity is high.
Arc extended surface tube full-automatic welding machine provided by the invention, it comprises extended surface tube automatic supplying machine structure, automatic milling pipe mechanism, extended surface tube automatic turning mechanism, fin automatic feed mechanism and extended surface tube automatic aligning mechanism, it also comprises fin automatic welding mechanism; Fin automatic welding mechanism comprises base, symmetry is arranged on two pneumatic propelling units on base, symmetry is arranged on two welding heads on pneumatic propelling unit, and symmetry is arranged on the clamping device on welding head, and symmetry is arranged on the weld cylinder on pneumatic propelling unit and holds out against cylinder.
Fin automatic welding mechanism also comprises the source of welding current being arranged on base, the conductor being connected with the source of welding current, and the electrode being connected with conductor, electrode is arranged on welding head.
The operation principle of arc extended surface tube full-automatic welding machine is: steel pipe is by the supply of extended surface tube automatic supplying machine structure, enter automatic milling pipe mechanism, mill pipe completes the precalculated position of being shifted onto welding head by cylinder, by hold out against cylinder hold out against steel pipe start welding, fin automatic charging coordinates vibration feeding system to complete by robot, control accurately, weld the complete extended surface tube automatic aligning mechanism that enters, by hydraulic system, alignment is carried out in bending position, when second extended surface tube alignment completes, automatically unload first extended surface tube.
Arc extended surface tube full-automatic welding machine provided by the invention, its beneficial effect is, adopts fin robot material loading, steel pipe automatic transport mode, has improved the welding efficiency of extended surface tube, welding quality stable, welding quality is good, and yield rate is high.Adopt oscillating cylinder can make fin be arbitrarily angled distribution, increased the flexibility of welding.One end holds out against steel pipe with holding out against cylinder F.F., and weld cylinder clips over there fin and slowly shifts onto and on steel pipe, start welding, makes fin firm welding be difficult for falling sheet.The supply of fin adopts feeding storehouse, spiral vibratory feed table, straight line feeder modular design, and the fin of whole feeding storehouse can be for one day, uses the upset of setting a table can realize fin vertical from laterally becoming, so that robot captures, realizes automatic feed operation.Adopt monolithic, biplate to divide angle to arrange the extended surface tube of welding, can further make full use of actual internal area, expansion heat-transfer surface, improves heat transfer property, augmentation of heat transfer.In the situation that ensureing heat, this extended surface tube that is angular distribution fin takes up space less, compact conformation.
