Description
Technical field
The utility model pipe end rolling device belongs to steel pipe's production field, specifically a kind of equipment producing dual-metal clad steel pipe with hydraulic pressure complex method.
Background technology
Pipe end roller press produces guardian technique equipment needed for composite bimetal pipe with hydraulic pressure complex method, and its Main Function shows: by pipe end roll extrusion, improves the making precision of steel pipe, can ensure carrying out smoothly of the soldering and sealing of subsequent technique pipe end and hydraulic pressure compound.
For hydraulic pressure bimetal composite multiple tube, its formation mechenism is as follows: by the inner and outer pipes two ends good seal assembled---the airtight long cylinder in pair of lamina, again liquid is injected in the socket of internal layer, by the pressure of the liquid in certain speed increased pipe, make internal lining pipe progressively diametric(al) expand, inwardly shrink at axial direction.By controlled pressurization, make internal lining pipe finally reach plastic deformation, outer base tube is still in regime of elastic deformation.Can work as and judge that internal lining pipe reaches plastic deformation by Pressure gauge or pressure sensor, when the elastic deformation that outer base tube reaches design requires, release pressure, compound completes.But this complex method requires high to pipe end, and pipe end will carry out soldering and sealing and prevent seepage from entering in the middle of double-metal layer, simultaneously pipe end internal diameter size will meet hydraulic press end socket and can enter pipe end smoothly and have suitable seal clearance for ensureing sealability.Hydraulic pressure composite algorithm domestic at present not yet processes pipe end, and easy like this exist following two problems:
1, the multiple tube after fit, internal lining pipe makes end bus and outer base tube fit because of the reason of self gravitation, and the gap of Up Highway UHW and outer base tube is then very large.So just make the gap between internal lining pipe and outer base tube just uneven, easily cause not prison welding solid when pipe end soldering and sealing, the defect such as uneven, even also can solder skip.Pipe end soldering and sealing poor quality, when easily to cause between double-metal layer water inlet and axial deformation, weld seam such as to tear at the problem, affects composite effect.
2, without after the multiple tube soldering and sealing of pipe end roll extrusion, the gap of double-metal layer is uneven, causes the center of outer base tube and internal lining pipe not overlap.When hydraulic pressure compound, clamp be outer base tube, base tube centralized positioning in addition, the center of compounding machine end socket and outer base tube center superposition, so just cause end socket center not overlap with internal lining pipe center, after end socket enters internal lining pipe, because of departing from of center,, if misalignment is large, even can there is the phenomenon that end socket enters not go internal lining pipe in the phenomenon that easy generation is poorly sealed.
Utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art, thus the combining efficient providing a kind of composite bimetal pipe being suitable for hydraulic pressure complex method to produce, convenient and swift, the simple pipe end roll unit of structure.
A kind of pipe end rolling device is become by the roller of mount pad, some quantity, securing member A, securing member B, securing member C, taper shank, retainingf key, adjusting shims.Each roller is made up of running roller, axle, needle bearing, shaft block ring, spacer A, taper roll bearing, thrust ball bearing, spacer B, round nut, stop washer.Thrust ball bearing, shaft block ring, needle bearing, spacer A, spacer B, taper roll bearing are arranged between running roller and axle, finally fix with stop washer and round nut.Roller is installed on mount pad in the mode of circumference uniform distribution, installs different adjustment pads, and be fixed on mount pad with securing member A according to different roll extrusion diametric requirements.Retainingf key is fixed on mount pad front end by securing member C.Mount pad is fixed on taper shank by securing member B.
Accompanying drawing explanation
Accompanying drawing 1 sectional view of the present utility model.
Accompanying drawing 2 right side structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
In figure: mount pad 1, running roller 2, axle 3, spacer A4, spacer B5, taper shank 6, retainingf key 7, adjustment pad 8, needle bearing 9, taper roll bearing 10, thrust ball bearing 11, round nut 12, stop washer 13, securing member A14, shaft block ring 15, securing member B16, securing member C17.
As shown in accompanying drawing 1 and accompanying drawing 2, a kind of pipe end rolling device is made up of the roller of mount pad 1, some quantity, securing member A14, securing member B16, securing member C17, taper shank 6, retainingf key 7, adjustment pad 8.Each roller is made up of running roller 2, axle 3, needle bearing 9, shaft block ring 15, spacer A4, taper roll bearing 10, thrust ball bearing 11, spacer B5, round nut 12, stop washer 13.Thrust ball bearing 11, shaft block ring 15, needle bearing 9, spacer A4, spacer B5, taper roll bearing 10 are arranged between running roller 2 and axle 3, finally fix with stop washer 13 and round nut 12.Roller is installed on mount pad 1 in the mode of circumference uniform distribution, installs different adjustment pads 8, and be fixed on mount pad 1 with securing member A14 according to different roll extrusion diametric requirements.Retainingf key 7 is fixed on mount pad 1 front end by securing member C17.Mount pad 1 is fixed on taper shank 6 by securing member B16.
Workflow of the present utility model:
1, multiple tube is loaded Working gantry
Multiple tube after fit is lifted to lifting conveying roller by the horizontal dolly that send, lifting conveying roller can regulate height according to caliber, pseudo-classic tube hub is lifted to slightly higher than clamp central, so that fixture enters pipe end, simultaneously can by the position of the conveying function adjustment multiple tube of running roller.
2, multiple tube is fixing
After multiple tube adjusts good position on lifting conveying roller, start mechanical skid plateform, the fixture be arranged on mechanical skid plateform table top advances by mechanical slide strips is dynamic, open fixture simultaneously, after multiple tube pipe end enters fixture, mechanical skid plateform stops, clamp pipe end, lifting conveying roller declines, by the fixture support multiple tube of two pipe ends.
3, pipe end rolling device roll extrusion
After clamp multiple tube pipe end, start unit head, unit head does length feed motion, the pipe end rolling device be arranged on its main shaft rotates, pipe end rolling device self is rotating and roll extrusion pipe end under the slow feed motion of eastern power head, the external diameter of pipe end rolling device is because of larger than internal lining pipe internal diameter, and in rolling process, internal lining pipe generation plastic deformation makes internal diameter become large, and the gap between internal lining pipe and outer base tube reduces and evenly.After pipe end rolling device straightway all enters internal lining pipe, the rotary motion of pipe end rolling device continues, the moving direction of unit head is reverse, rotation limit, pipe end rolling device limit is exited, and after pipe end rolling device exits pipe end completely, unclamps fixture, multiple tube is lifted in lifting conveying rising, start mechanical skid plateform afterwards, slide unit drives fixture to retreat, and horizontally send little handlebar to be transported on next process through the multiple tube of pipe end rolling device roll extrusion.
