The specific embodiment
Below in conjunction with accompanying drawing the production technology of the double-faced corrugated metal pipe of the present invention's proposition and the structure and the principle of manufacturing equipment are described in further details:
Be depicted as the shape and the plan view of double-faced corrugated metal pipe as Fig. 1 a, b, i.e. the ripple annulus that is pressed on the tube wall 16 in the middle of the metal tube with crest 17, trough 18, the number that can choose the ripple annulus as required can be one or more, and, height e1, the e2 of crest 17 and trough 18 can be identical, also can be different (be e1＞e2, or e1＜e2).
Be depicted as the structure chart of making double-faced corrugated metal pipe equipment and auxiliary equipment as Fig. 2 and Fig. 3 a, b.
The structure of manufacturing equipment comprises: have upper and lowerly in framework 9, the framework to be fixed with in opposite directions the rotating shaft 3,7 of rotating, wherein going up axle is active rotating shaft 3, lower shaft is a driven spindle 7, drive active rotating shaft 3 by power set 1 and rotate, driven spindle is then by having 2 or 4 change gear case 2 drive rotations that the identical gear of diameter is formed.Main shaft and from the rotating shaft according to the alternate mould circle wheel 5 that is fixed with of the number of pressed metal tube wave line, the two ends of driven spindle be installed with by drive link 10 through changed course gear driven elevating lever 8 form can synchronous upper and lower displacement lifting or gearshift.In addition, fixedly the pedestal 6 of framework one end of active rotating shaft connects with frame hinge, the fluted annulus 4 of cover on the axle between the mould circle wheel changes
Auxiliary equipment comprises: have the inner supporting circle of metal chock breach 12, fixing hole 15 and have the outer cranse of breach 12, fixing hole 15, wherein on inner supporting circle, have one its highly be less than or equal to the platform 13 of metal tube tube wall.
The method step that utilizes the said equipment to make double-faced corrugated metal pipe is:
At first inner supporting circle 11 is inserted in the two ends of metallic cylinder, and barrel 16 is snapped in the platform 13, and utilize metal chock (not shown) to insert in the breach 12, make chock with the inner supporting circle stretching, again outer cranse 14 is inserted in the cylinder two ends and inserts in the fixing hole 15, cylindrical wall 16 is clamped with screw rod.
Second step, open pedestal 6, the metallic cylinder that two ends is fixed with support ring and cranse is inserted on the mould circle wheel 5 of driving shaft 3, and closed-lock pedestal 6.
The 3rd step, open the synchronous lifting device driven spindle of forming by elevating lever 8 and drive link 10 7 and rise, make the mould circle wheel 5 in the driving and driven rotating shaft compress metallic cylinder.
The 4th step, device turns on the power, the moving rotating shaft 3,7 of principal and subordinate drives alternate mould circle wheel 5 and rotates with the speed that per minute 30-150 changes, simultaneously lowering or hoisting gear promotes driven spindle 7 with the speed of per minute 2-5mm and draws close to active rotating shaft 3, makes that alternate fixing mould circle wheel 5 extrusion cylinder barrels make it form two-sided ripple in two rotating shafts.Because the wheel limit of mould circle wheel 5 is to be fixed with groove annulus 4 between smooth camber and mould circle wheel, so the crest 17 of the two-sided ripple of institute's extrusion modling, trough 18 moulding are smooth.In addition, by adjusting the size of the mould circle wheel 5 on active rotating shaft or the driven spindle, the depth of crest 17, trough 18 on can the formed metallic cylinder of corresponding adjustment can also be by adjusting the distance between the mould circle wheel 5, to adjust the spacing of ripple on the formed metallic cylinder.
The 5th step behind the two-sided ripple forming on the metallic cylinder, descended elevating lever 8, and active rotating shaft and driven shaft draw back certain distance, open pedestal 6, pull out cylinder.The lock ring cranse 14 outside its two ends inner supporting circle 11 of dismantling, i.e. double-faced corrugated metal pipe moulding.
Utilize this special equipment and technology can produce the double-faced corrugated metal pipe of diameter between DN200-300mm of 1,2 or a plurality of ripples according to need, it is simple to have processing technology, the advantage that production cost is low.
