Description
Technical field
The present invention relates to a kind of laser welding wire-feeding mechanism, belong to Laser Processing corollary apparatus field.
Background technology
Along with science and technology development, in transportation manufacturing industry such as Aero-Space, navigation and automobile,, improve transport capacity in order to alleviate the deadweight of delivery vehicle, more and more adopt light metal material.High strength alumin ium alloy, is widely used in the transportation manufacturing industry with its good physics, chemistry and mechanical performance as a kind of important light metal material.For a long time, the riveting process that falls behind is still used in the connection of aluminium alloy plate equipment structure at present, causes dead load to increase, and adopts traditional fusion welding method welding aluminum alloy, and the Welding Structure deflection is big, and property of welded joint is poor.Because laser weld laser energy density height, welding seam deep width ratio is big, and the zone of action is little, and the weld heat-affected zone territory that obtains is little, greatly reduces welded distortion, and laser weld obtains application more and more widely.Problems such as weld porosity, HOT CRACK FOR WELDING P and the joint that the aluminium alloy laser weld also exists general melting welding often to run into inevitably is softening.Adopt the aluminium alloy laser weld of filler wire, because the use of welding wire, changed the composition of weld seam on the one hand, refinement weld grain, significantly improved weld seam cracking resistance line performance.On the one hand, weld hardness also is enhanced, even surpasses the hardness of mother metal.On the other hand, reduce the critical power density of aluminium alloy Laser Deep Penetration Welding, helped the stability of penetration fustion welding.Simultaneously, help improving welded stress deformation, the surface forming quality is enhanced.The aluminium alloy wire filling laser welding is different from general arc-welding, and its focal beam spot diameter is very little, and generally below 1mm, the part swing of aluminium welding wire can make the welding process instability even can interrupt, and the aluminium welding wire that therefore requires to send has good outspoken nature and directive property.
Wire feeder is an indispensable device in the wire feed technology, and existing wire feeder can be divided into three kinds: push-wire-type, wire drawing type and push away-wire drawing type.They are to utilize a pair of wire feed rolls or the wire feed rolls more than two pairs and the frictional force between the welding wire to come wire feed.At present, these wire feeders mainly are to be used for arc-welding, and for arc-welding, the swing of welding wire part does not cause tangible influence to welding process.And the aluminium alloy wire filling laser welding, because aluminium welding wire is softer, the contact area of aluminium welding wire and wire pushing roller is little, very easily be crushed when sending and bending, after chewing, seal wire has a strong impact on the directive property of aluminium welding wire, aluminium welding wire is beat near the laser focal beam spot, simultaneously also increased aluminium welding wire in seal wire is chewed resistance in addition plug wire appears.
Be illustrated in figure 2 as the aluminium alloy laser weld wire feeder schematic diagram of a prior art push-wire-type, it comprises down-pressure roller 1, aluminium welding wire 2, goes up pressing roller 3 and driving wheel 9.The shortcoming of this wire feeder is, the down-pressure roller 1 of wire feeder is the some contact with last pressing roller 3 with contacting of aluminium welding wire 2, and contact area is little, adjusts the pressure size of contact roller before the welding repeatedly, pressure is crossed between trundle and the aluminium welding wire and is skidded, and causes wire feed inhomogeneous; The excessive aluminium welding wire that causes of pressure has impression or distortion, and aluminium welding wire enters seal wire and chews back resistance increase, and aluminium welding wire is beat near hot spot, even plug wire occurs, influences the stability of welding process.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of realize that the aluminium welding wire of sending is indeformable, have the laser weld wire feeder of good outspoken nature and directive property.Not only wire feeding force is big in the present invention, wire feed at a distance, but also can the alignment aluminium welding wire, thus the stability of assurance aluminium alloy laser weld.
The technical solution adopted for the present invention to solve the technical problems is: comprise frame 6 and be connected driving wheel 9, driven pulley 8, motor 4, decelerator 5 on the frame 6, last pressing roller 3, down-pressure roller 1, also comprise the adjusting position wheel 13 that sets gradually along the wire feed direction, vertically alignment roller set 7a, laterally alignment roller set 7b, be arranged between pressing roller 3 and the aluminium welding wire 2, between down-pressure roller 1 and the aluminium welding wire 2 two pinch flat rubber belting 10; Wherein, motor 4 and decelerator 5 are fixed on the below of frame 6, and motor 4 is fixedly connected on the decelerator 5, and the output shaft of motor 4 is connected with the input hole of decelerator 5, driving wheel 9 is connected on the output shaft of decelerator 5, and two pinch flat rubber belting 10 and are connected on two pairs of driving wheels 9 and the driven pulley 8.
Above-mentioned flat rubber belting 10 surface abrasion resistances that pinch have the alignment function.
Above-mentioned down-pressure roller 1 and the driven pulley 8 that pinches flat rubber belting 10 all can be regulated its pressure.
Above-mentioned adjusting position wheel 13 can be regulated the entrance height of aluminium welding wire 2 by the adjustment screw of its below.
Above-mentioned down-pressure roller 1, on all have in the middle of the pressing roller 3, driven pulley 8 and prevent that aluminium welding wire 2 from pinching flat rubber belting pinches length travel in the process arc-shaped groove.
For the ease of regulating the stability of wire feed rate and assurance wire feed rate, motor 4 can adopt AC servo motor.
The acute angle of above-mentioned vertical alignment roller set 7a and horizontal two alignment directions of alignment roller set 7b is 80 °～90 °.Each alignment roller set all includes the alignment roller of 5～9 branches, two row's interlaced arrangement, wherein, the fixed idler whell number equals adjustable roller number or Duos 1 than adjustable roller number, 3～5 is fixed idler whell, its axle is fixed on the frame 6, other 2～4 is the adjustable roller in position so that regulate the alignment aluminium welding wire, and its axle is fixed on the slide block of regulating by adjustment screw 12 11.In addition, when the angle of two alignment directions is 90 °, scheme the best when each alignment roller set all has the adjustable roller of 4 fixed idler whells and 3.
The invention has the beneficial effects as follows, many last pressing roller and down-pressure roller are compressed the softer flat rubber belting that pinches aluminium welding wire by adopting, increased the contact area of aluminium welding wire and flat rubber belting, reduced the pressure of aluminium welding wire unit are, the aluminium welding wire of sending is indeformable, wire feeding force is big, at a distance wire feed; In addition, the present invention is by aligning mechanism alignment aluminium welding wire, and the aluminium welding wire of sending has good outspoken nature, thereby guarantees the stability of laser weld filling aluminum welding wire.The present invention be a kind of simple to operate, can remote wire feed, institute's softer aluminium welding wire that send is indeformable, wire feed is reliable and stable, has the laser weld wire feeder of alignment function.
