Fig. 1 is the schematic perspective view according to the preferred embodiment of aluminium of the present invention and aluminium alloy helix tube moulding welding equipment.
Fig. 2 is the sectional view according to the preferred embodiment of aluminium of the present invention and aluminium alloy helix tube moulding welding equipment.And
Fig. 3 is the schematic diagram according to the preferred embodiment of the stirring-head of aluminium of the present invention and aluminium alloy helix tube moulding welding equipment.
The specific embodiment
Below the present invention is described in further detail, can implement according to this with reference to the specification literal to make those skilled in the art.Fig. 1 is the schematic perspective view according to the preferred embodiment of aluminium of the present invention and aluminium alloy helix tube moulding welding equipment.Fig. 2 is for establishing the sectional view of the preferred embodiment of each according to aluminium of the present invention and aluminium alloy helix tube moulding welding.Fig. 3 is the schematic diagram according to the preferred embodiment of the stirring-head of aluminium of the present invention and aluminium alloy helix tube moulding welding equipment.As Fig. 1, Fig. 2, shown in Figure 3, aluminium and aluminium alloy helix tube moulding welding equipment comprise: helix tube shaped device (not shown), and it is fixedly mounted on an end of frame; The agitating friction welder, it is fixedly mounted on the other end of described frame, and described agitating friction welder comprises: the high-speed electric expreess locomotive (not shown); Stirring-head 1, it is connected on the output shaft of described high-speed electric expreess locomotive, comprises mixing needle 12 and two shaft shoulders 10,14, and mixing needle is between described two shaft shoulders; And organize live-rollers more, comprise 2, two groups of supporting pad rollers 3 of two groups of pinch rolls, two groups of support sticks 4.Wherein, pinch roll is in order to prevent that pipe seam from opening and misplace; Backing roll is in order to prevent from welding the preceding pipe distortion that is shaped; The supporting pad roller be for the shaping of the pipe after guaranteeing to weld good.Described many group slewing rollers are arranged on the described agitating friction welder rotationally, are used for supporting aluminium and aluminium alloy coiled material 8, the pipe seam of alignment pipe.Preferably, described agitating friction welder also comprises the deburred device, as scraper plate 5, and burnishing device, as polishing roller 6.Deburred device and burnishing device are used for carrying out deburring processing and polishing.The shaft shoulder of stirring-head is that arc supports covering of the fan 11,13 towards the two sides of helix tube.Usually, adopt the friction stir weld mode to produce aluminium and aluminium alloy spiral welded pipe, because the parent metal that to-be-welded region does not increase newly, as welding wire etc.So weld bead height does not increase, also slightly reduce on the contrary.This is lower than the problem of parent metal field strength with regard to causing welded seam area intensity, makes tubing have the weld strength defective.Stirring-head by this shaft shoulder can make weld seam middle part protuberance, strengthens the intensity of weld part.Aluminium and aluminium alloy helix tube moulding welding equipment also comprise industrial computer, display unit 9 and camera 7, adopt video and industrial computer to realize the accurate control of welding process, and the digitlization of welding parameter input, control and record.Can adjust and optimize welding parameter at any time.Can realize that the prescriptionization of different grade aluminium alloy welding parameters calls.
