The specific embodiment
Illustrate by Fig. 1 and Fig. 2, a kind of forming processing device of metal spiral welded tube, mainly form by shaping mould 1 and forming angle adjuster 2, wherein: the member outer sleeve 11 of forming shaping mould 1 is fixedlyed connected with the V-type part 19 of chassis seating 18, outer sleeve 11 1 ends are provided with the strip material mouthful A that goes forward one by one, so that be with going forward one by one of steel, the other end is provided with the outlet B of moulding pipe fitting 20, and be connected with end cap 13 by bolt in this end, before the outer sleeve 11, after ball 17 all is installed, between two outside outer sleeves 11 of rolling bearing 14 and moulding pipe fitting 20, be provided with ball retainer 16, ball 17 is fixed between outer sleeve 11 inwalls and the moulding pipe fitting 20 by ball retainer 16, one collar 12 is installed in the middle of rolling bearing 14, the periphery of the collar 12 and outer sleeve 11 inwalls are by being tightly fixed, its inner headed face directly contacts with moulding pipe fitting 20, position at the collar 12 places, on the collar 12 and outer sleeve 11 on position corresponding with it respectively have a welding gun hand-hole 111, left and right sides at the collar 12 respectively is provided with a rolling bearing 14, between the inner ring of rolling bearing 14 and moulding pipe fitting 20, sizing sleeve 15 is installed, rotating disk 21 is fixedlyed connected with chassis seating 18 by bolt, and outer sleeve 11 is adjusted forming angle by coupled forming angle adjuster 2.
The collar 6 is installed in the middle of the rolling bearing, and its periphery and outer sleeve inwall connect as one by being tightly fixed, and its inner headed face directly contacts with the moulding pipe fitting, and the center line of its width overlaps with the half pitch position of helix tube.
Ball 17 helix vertically is evenly distributed on the ball retainer 16, and its pitch angle alpha will is consistent with the moulding helical angle of made pipe fittings.
Rolling bearing 14 and sizing sleeve 15 are installed between two ball retainers 16, adopt interference fit in a small amount between the outer ring of rolling bearing 14 and outer sleeve 11 inwalls, relative position maintains static between them to keep, sizing sleeve 15 is fixed between the inner ring and moulding pipe fitting 20 of rolling bearing 14, closely cooperate with rolling bearing 14 inner rings, so that they are fixedly installed togather, sizing sleeve 15 can drive rolling bearing 14 under the drive of circumferential frictional force of band steel inner ring is done together and is rotated in a circumferential direction, along with rolling bearing 14 inner rings rotate.
The collar 12 is fixedly mounted in the middle of the rolling bearing 14, and the midline position of its width coincides with the C place, half pitch position of relative moulding pipe fitting 20.
Forming angle adjuster 2 is by rotating disk 21, rotating shaft 22, and worm gear 23, worm screw 24 and pedestal 25 constitute, and its shaft 22 is fixedlyed connected with rotating disk 21 by metallic bond, and worm gear 23 is fixed in the rotating shaft 22, and worm gear 23 and worm screw 24 are meshing with each other.
The internal diameter of sizing sleeve 15 is consistent with the final diameter of moulding pipe fitting 20 moulding of wanting, and is sliding friction between them.
In the helix tube forming process, can can regard shaping mould 1 as outer sleeve 11 that many balls 17 are installed on the inwall basically, when the band steel is advanced in the shaping mould 1 by brute force with a certain special angle mouthful A that gone forward one by one by strip material continuously by delivery apparatus, the band steel promptly rolls into helical form automatically in mould under the effect of ball 17, helical form band steel is through sizing sleeve 15 and the collar 12 carries out diameter and the weld seam adjustment makes moulding more regular, the weld seam merging precision is higher, and with fusing process of intermediate or by spot welding it is welded into helix tube at half pitch place.To the individual layer thin walled helical tube, only need carry out the welding that melting welding just can be finished pipe fitting at pipe fitting half pitch place, and for thicker metal tube and the bimetal tube that needs to adopt silk filling of tube wall, the molten bath has outstanding then can carry out local spot welding at half pitch place earlier, carries out the precision welding again at one or one and half pitch places then.Because shaping mould 1 is fixed on the forming angle adjuster 2, forming angle adjuster 2 is the worm gear-endless screw system, when rotary worm, can drive shaping mould 1 by worm gear 23 and rotate, thus the adjusting of realization forming angle.
The deformation force of band steel and the brute force that propulsive force all derives from delivery apparatus are sent, wherein most radial deformation power are passed to ball 17 by the band steel, ball 17 is directly passed to outer sleeve 11, few part radial deformation power is when helical form band steel process sizing sleeve 15, pass to sizing sleeve 15 by the band steel, sizing sleeve 15 passes to rolling bearing 14 again, and rolling bearing 14 passes to outer sleeve 11; Because between sizing sleeve 15 and the moulding pipe fitting 20 is sliding friction, so most of axial advance power passes to sizing sleeve 15 by the band steel, 15 in sizing sleeve passes to rolling bearing 14 with power, rolling bearing 14 passes to power the ball retainer 16 of shaping mould rear end again, on institute's end cap that is delivered to 13, end cap 13 finally passes to outer sleeve 11 by connecting bolt then; And wherein the small part axial force has passed to ball 17 by the band steel, ball 17 passes to power ball retainer 16 again, the ball retainer 16 of front end is successively passed to end cap 13 through the ball retainer 16 of rolling bearing 14 and rear end with power again, pass to outer sleeve 11 at last, and the ball retainer 16 of rear end is directly passed to power end cap 13, passes to outer sleeve 11 at last.All have the hole of a Φ 30 on the outer sleeve 11 and the collar 12 with respect to the upper end at pipe fitting half pitch place, its purposes is exactly that the rifle head of melting welding or spot-welding gun can be stretched in the mould, aims at weld seam and implements welding.
