The specific embodiment
Following the present invention combines the embodiment in the accompanying drawing to further describe:
Fig. 1 is the internal organs view of major equipment among the present invention.There is a feeding unit 4 on main frame 1 left side, and the right of main frame 1 is followed successively by dent puller 2 and traction machine 3.The compound rail manufacturing line of actual steel aluminium respectively has a traction machine 3 and at least four feeding units 4 is respectively arranged on main frame two limits, long and more than 15 meters to adapt to the compound rail length of steel aluminium.Feeding unit 4 is unpowered, and 2 backup guide rolls are arranged on the frame of each feeding unit, lays without compound aluminium section bar 27 on the deflector roll of the feeding unit 4 on main frame 1 left side, places stainless steel tank 29 on it again.The feeding unit on main frame 1 the right is laid the compound rail finished product 22 of steel aluminium.Traction machine 3 produces material or the mobile from left to right part power of finished product.Main frame 1 is made up of five parts, is followed successively by preparatory complex group 5, main complex group 6 from left to right, repeats to set up jointly 7, vertically modulating mechanism 8, level(l)ing mechanism 9.Three combinations 5,6,7 in the left side and the right combination 9 have four pairs of horizontal pinch rollers 14 on the main frame 1.The critical component of dent puller 2 is shaping wheels 18.The nonstraightness that two mechanisms 8 in the right and 9 are used for proofreading and correct the compound rail of steel aluminium in the main frame 1.Vertically modulating mechanism 8 is used for regulating vertical nonstraightness.Two accent rollers 15 that hang down of passive rotation are unmodifieds at vertical width between centers.The a pair of horizontal pinch roller 14 of level(l)ing mechanism 9 all is a follower; Each links to each other with pinch roller driving and reversing mechanism 16 respectively; This is to bearing center of horizontal pinch roller 14 a bit of distance that staggers longitudinally; So level(l)ing mechanism both can be used for proofreading and correct the nonstraightness of compound rail 22 horizontal directions of steel aluminium, also can be used for making the compound rail of steel aluminium crooked by predetermined arc.Actuating unit 10 is used to drive 18 rotations of shaping wheel, and the actuating unit of traction machine 3 is identical with the actuating unit 10 of dent puller 2.Actuating unit 11 is used for the vertical pinch roller 13 and the horizontal pinch roller 14 of three combinations 5,6,7 in driving host 1 left side, all is to drive the axle rotation on the pinch roller by electromagnetic variable speed motor through drop-gear box and chain, sprocket wheel 12 earlier.And the passive pinch roller of corresponding active rotation pinch roller connects together with pinch roller driving and reversing mechanism 16, regulates the degree that compresses up and down or be out of shape to the compound rail 22 of steel aluminium.But the actuating unit of the actuating unit 11 of main frame 1, the actuating unit 10 of dent puller 2 and two traction machines 3 has quadruplet electrical motor synchronous variable-speed, and the compound rail manufacturing line of steel aluminium front and back are coordinated.The horizontal pinch roller 14 of the bevel gear 26 of main complex group 6 and active rotation is at the left of longitudinal centerline in the main frame 1; And preparatory right-hand at longitudinal centerline of complex group 5 and the horizontal pinch roller 14 that repeats to set up jointly 7 active rotation; This arrangement can make rotation and the distortion of two journal stirrups 28 in recombination process of aluminium section bar 27 more even, avoids the tight pine on one side of tightening degree of 28 pairs of stainless steel tanks 29 of two journal stirrups on one side.Thereby the straightness accuracy of the compound rail 22 of horizontal direction steel aluminium is better.
Fig. 2 is the lateral plan of main frame 1 of the present invention and dent puller 2.5 combinations are housed on the pedestal of main frame 1, are followed successively by preparatory complex group 5, main complex group 6 from left to right, repeat to set up jointly 7, vertically modulating mechanism 8, level(l)ing mechanism 9.First three combination 5,6,7 of the left side all has pinch roller driving and reversing mechanism 16 to link to each other with superposed vertical pinch roller 13, so the high and low position of the vertical pinch roller 13 on top is adjustable.And the position that is positioned at three vertical pinch rollers of bottom in these three combinations is fixed.The diameter of all vertical pinch rollers 13 is identical, and the height of the compound rail 22 of the steel of void ratio up and down aluminium between the every pair of vertical pinch roller 13 is slightly smaller.Main complex group 6 and the semi-sictional view that repeats to set up jointly 7 have reflected the assembly relation of horizontal pinch roller 14 and axle and bearing.Main complex group 6 and the vertical line of centers that repeats to set up jointly each a pair of vertical up and down pinch roller 13 of the 7 a bit of distance L that staggers longitudinally.Can avoid the compound rail 22 of steel aluminium to be ingot-shaped upwarping like this.The top that contacts with vertical pinch roller 13 is corrosion-resistant steel, and friction coefficient is about 0.1; The bottom is an aluminium section bar, and friction coefficient is about 0.2.The two differs nearly one times, and therefore, the moment that the compound rail half-blank of steel aluminium is crossed every pair of vertical pinch roller is the balance of trying to achieve the mechanics neutral line, must calculate to remedy the required distance L value of the inconsistent mechanical balance that brings of friction coefficient.On the vertically modulating mechanism 8 of dent puller 2 and main frame 1 a pair of left and right sides position-limited wheel 19 is arranged respectively, be used for controlling the compound rail half-blank of steel aluminium, two diagonal bars 32 of shaping wheel 18 are pressed on two journal stirrups 28 of aluminium section bar 27 exactly in the tram, the left and right sides of horizontal surface.Except that vertically modulating mechanism 8, the frame 20 of all the other 4 combinations on the main frame 1 all is identical.The side of each frame 20 all is furnished with deflector roll 17.The line of the vertex of all bottom deflector rolls becomes the level run line of the compound flange of rail face of steel aluminium, and the line of the nadir of all top deflector rolls becomes the level run line of the compound tread face of steel aluminium.So these deflector rolls have the certain effect in the compound rail nonstraightness of orthocorrection steel aluminium.The shaping of dent puller 2 wheel 18 links to each other with driving and reversing mechanism 16, and the upper-lower position of shaping wheel 18 is adjustable, and another roller center below the shaping wheel is fixed.
Fig. 3 repeats to set up jointly 7 right cutaway view in the main frame 1 of the present invention.Fixing two frames 20 on the pedestal of main frame 1.The bearing seat of lower shaft 24 directly is fixed on the pedestal of main frame 1.The top of two frames 20 about two pinch roller driving and reversing mechanisms 16 are separately fixed at.The bearing seat of last axle 23 2 ends then is positioned at the screw mandrel end of pinch roller driving and reversing mechanism 16.This mechanism utilizes handwheel to make screw mandrel make bearing seat drive the last vertical pinch roller of going up on the axle 23 13 with respect to the rotation of captive nut and moves up and down, scalable and be contained in the gap between the following vertical wheel 13 on the lower shaft 24.The locking wheel of driving and reversing mechanism 16 handwheels below then is used to keep the height in this gap constant.This gap and the fine difference of compound rail 22 actual heights of steel aluminium have determined the compressing degree of 13 pairs of compound rails 22 of steel aluminium of vertical up and down pinch roller.On the last axle 23 the grating chi is housed and is connected to digital display device 25, can accurately reflect the state that moves up and down of axle 23 and the variation in gap.Two bearing seats are housed on the frame 20 on the left side are used for installing vertical pivot 21, the bevel gear of vertical pivot 21 lower ends is meshed with bevel gear on the lower shaft 24.When the sprocket wheel on the lower shaft 24 12 rotated, the horizontal pinch roller on the vertical pivot 21 also can rotate, and the bevel gear number of teeth is 2 times of vertical pivot 21 below bevel gears on the lower shaft 24.The diameter of the vertical pinch roller 13 on the lower shaft 24 is 2 times of horizontal pinch roller diameter on the vertical pivot 21, so just makes vertical pinch roller 13 have identical linear velocity with horizontal pinch roller 14 circumferential surfaces.The diameter of vertical pinch roller 13 is obtained bigger, makes up and down that the pressure of vertical 13 pairs of compound rails 22 of steel aluminium of pinch roller reduces, and is difficult for causing the local aluminum alloy deformation.The driving and reversing mechanism 16 of horizontal direction is housed on the frame of the right, regulates horizontal pinch roller about 14 advance and retreat on the right.The position of the horizontal pinch roller 14 on the right of the grating chi of here installing can accurately reflect with digital display device 25, thereby the accurate degree that is adjacent to of the degree of rotation of two journal stirrups 28 of 14 pairs of compound rails 22 of steel aluminium of the horizontal pinch roller of adjustment and steel and aluminium.Have locking wheel on the pinch roller driving and reversing mechanism 16, can be used for keeping the tightening degree of this journal stirrup degree of rotation and steel and aluminium, keep the stability of producing.
Fig. 4 is the left cutaway view of complex group 6 in the main frame 1 of the present invention.Fig. 4 is similar with Fig. 3, and just Fig. 4 middle sprocket 12 is positioned at the lower right.Because the side of dissecing
of Fig. 3 and two views of Fig. 4 is opposite; Reflected the horizontal pinch roller 14 of vertical pivot 21 and active rotation in two views the position each at the longitudinal centerline right and left, this is the consistent important measures of tightening degree that guarantee 28 pairs of stainless steel tanks 29 of aluminium section bar 27 2 journal stirrups.
Fig. 5 sets up the partial enlarged drawing at the core position of 7 (Fig. 3) jointly for repeating in the main frame 1 of the present invention.Figure central part be the compound rail 22 of steel aluminium, be up and down vertical pinch roller 13, about be horizontal pinch roller 14.Aluminium section bar 27 is I-shape, and two journal stirrups 28 of its top two sides are outwards open before compound, and stainless steel tank 29 can be put into the groove of aluminium section bar 27 from top to bottom.Because the gap between the vertical up and down pinch roller 13 is slightly less than the height of the compound rail 22 of steel aluminium; Vertical pinch roller produces the squeese pressure to the compound rail 22 of steel aluminium; This squeese pressure is mainly born by the bottom of the concave arc groove 31 of horizontal pinch roller 14; So the application force of vertical 13 pairs of aluminium section bar 27 bottom surfaces of pinch roller is less, can avoid the waist distortion of aluminium section bar 27 like this, keep the height of the compound rail 22 of steel aluminium constant.In the preparatory complex group 5 of main frame 1, the circumferential surface of horizontal pinch roller 14 is smooth.Main complex group 6 with repeat to set up jointly in 7, the circumferential surface of horizontal pinch roller 14 has concave arc groove 31.The concave arc groove 31 of main complex group 6 is wide and shallow, and it is narrow and dark to repeat to set up jointly 7 concave arc groove 31.Two journal stirrups 28 have inwardly rotated 12 ° after aluminium section bar 27 and stainless steel tank 29 are simultaneously through the preparatory complex group of main frame 1; Through having rotated 6 ° after the main complex group again; Each journal stirrup corotation 18 °; Two journal stirrups are being compelled to crimp when repeating to set up 7 concave arc groove 31 jointly, and two journal stirrups tightly touch the outside of two hypotenuses of stainless steel tank 29.The gradient of hypotenuse reaches 8 °～15 °.After leaving main frame, this distortion has kept the power that forever is adjacent to the inner plane of the upper surface of aluminium section bar 27 and stainless steel tank 29, and steel and aluminium are combined into the less steel-aluminium composite conducting rail of contact resistance 22.
Fig. 6 is the right cutaway view Amplified image of shaping wheel 18 and the compound rail 22 of steel aluminium in the dent puller 2 of the present invention.There are two circle diagonal bars 32 just in time to push down the wedge angle of two journal stirrups 28 of aluminium section bar 27 on the shaping wheel 18 of dent puller 2.When aluminium section bar 27 passes through here together with stainless steel tank 29; The wedge angle of two journal stirrups 28 is out of shape from top to bottom, tightly touch two skew back limits of stainless steel tank 29, and steel and aluminium are more firmly compound; Steel aluminium contact resistance is littler; Also eliminated the gap of sharp corner steel and aluminium, both attractive in appearance, can prevent that again the dust productive set is in the slit.
Installation and Debugging in factory after all devices of the compound rail manufacturing line of steel aluminium comes out by drawing machine up.Compound rail 22 parameters of the steel aluminium of each description are different; The corresponding adjustment in position on the manufacturing line between each pinch roller, the compound rail 22 of the steel aluminium of same description just can be produced kilometers up to a hundred continuously afterwards, and left side material is entered; The right finished product comes out, and stably implements batch manufacturing.
