Abstract
The utility model discloses a device for forming and processing metallic helically welded pipe, wherein a forming mould consists of a socket, a rolling ball, a rolling ball support bracket and a chassis; the rolling ball is fixed between the internal wall of the socket and a forming pipe fitting; the socket and the rolling ball support bracket are provided with a welding device intake port and an access opening; in addition, the socket regulates forming angle through a forming angle regulator connected with the socket. The device possesses small forming resistance and high forming precision and is particularly suitable for manufacturing thin-wall metallic helically welded pipe and double metallic helically welded pipe with precious metal layer.
Description
The utility model relates to a kind of manufacturing equipment of metal tube, especially relates to the spiral welded pipe forming processing device.
At present, the common metal spiral welded pipe has two types former both at home and abroad.A kind of is the sleeve forming device of sliding friction, and another kind is based on the full roller shell former of the rolling friction of three roll bending plate principles.The former moulding is accurate, good to be adjusted, but frictional resistance is big, must water oil to the surface of sleeve and pipe friction, so destroy welding surroundings, and weld seam is easy to generate pore, only uses this former to produce low pressure pipeline in friendship is welded frequently at present.The full roller shell former of the latter is owing to be rolling friction, so shaping resistance is little, need not water oil.At present, major diameter long-distance transport pipes such as general oil gas, the spiral welded pipe of employing all is this formers.Because it adopts the double-submerged arc manufacturing, cause its moulding and guiding mechanism complexity, the accent type is time-consuming, take material, and is difficult to point-device assurance weld gap.Particularly require moulding accurate, guarantee minimum weld gap, and adopt fusing process of intermediate that above-mentioned two kinds of formers all are difficult to satisfy such manufacturing requirement for thin-walled spiral welded pipe and the double metal spiral welded tube that has a layer of precious metal.
Goal of the invention of the present utility model provides a kind of forming processing device of making thin-walled spiral welded pipe and double metal spiral welded tube, and it can guarantee accurate moulding and weld gap, and the shaping resistance of implementing molten solder and generation in high quality is little.
To achieve these goals, the utility model provides a kind of forming processing device of metal spiral welded tube, mainly comprise: the shaping mould and the forming angle adjuster that are used for formation of tubes, its characteristics are: described shaping mould is made up of sleeve, ball and the ball bearing frame and the chassis that have the outlet of sheet metal strip charging aperture and moulding pipe fitting, the ball that is installed on the ball bearing frame is fixed between described sleeve lining and the described pipe fitting, have the welder inlet or the hand-hole of weld metal band on described sleeve and ball bearing frame, described sleeve is fixedly mounted on the chassis; Described forming angle adjuster is made up of rotating disk, rotating mechanism and base, and described rotating disk is driven by the rotating mechanism that is fixed on the described base; Described chassis and described rotating disk link together.
Above-mentioned forming processing device, its characteristics are: described charging aperture is opened at described sleeve top downside, the pipe fitting outlet that is provided with flange-interface is arranged on the end of described sleeve: the ring flange that the center has through hole is connected as a single entity with described flange-interface is concentric by bolt, described sheet metal strip is involved in by described charging aperture, is rolled out by described ring flange through hole.
Above-mentioned forming processing device, its characteristics are: described ball spiral vertically is evenly distributed on the described ball bearing frame, and its helical angle is consistent with the helical angle of made pipe fittings.
Above-mentioned forming processing device, its characteristics are: described rotating mechanism is made up of worm screw, worm gear and rotating shaft, and described worm screw and described worm gear mesh together, and described worm gear is fixed in the rotating shaft that connects with described jog key.
Above-mentioned forming processing device, its characteristics are: described chassis adopts bolt to be connected with described rotating disk.
Above-mentioned forming processing device, its characteristics are: described welder inlet or hand-hole are arranged on described sleeve top, half pitch place of described relatively pipe fitting.
Adopt said structure, make finishing die become the sleeve that many balls are installed on the inwall, when the band steel advanced continuously in the shaping mould by brute force with a certain special angle, the band steel promptly in mould, roll into helical form automatically, in the biting point and half pitch place with fusing process of intermediate with its spiral welded pipe that is welded.Because shaping mould is fixed on the forming angle adjuster, the forming angle adjuster is the worm gear-endless screw system, when rotary worm, promptly rotates by the worm gear drives shaping mould, thereby realizes the forming angle adjusting.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing
Fig. 1 is the structural representation of shaped device described in the utility model
In Fig. 1, this device is made up of shaping mould and forming angle adjuster, and shaping mould mainly is made up of sleeve 1, ball 2, ball bearing frame 3 and chassis 4.One breach A is also arranged at the end bottom at sleeve 1 and ball bearing frame 3, is convenient to steel band and sends to; The other end at sleeve 1 is a flange-interface, by bolt with this flange-interface and concentric being connected as a single entity of a ring flange, the transmission of realizable force.Radial deformation power is passed to ball 2 by steel band, and ball 2 is directly passed to sleeve 1, and axial advance power then passes to ball 2 by steel band, and ball 2 passes to ball bearing frame 3, and ball bearing frame 3 passes to sleeve 1 by flange and connecting bolt again.Have the hole of a φ 50mm at corresponding half pitch place, the top of shaping mould, its purposes is for soldering tip B stretches in the mould, aims at weld seam and implements welding.
The chassis 4 of sleeve 1 below is connected as a single entity by rotating disk 10 rigidity on bolt and the forming angle adjuster.The forming angle adjuster mainly by; Rotating disk 10, worm screw 7, worm gear 8 and rotating shaft 9 and support 11 are formed, and worm screw 7 meshes together with worm gear 8, and worm gear 8 is fixed in the rotating shaft 9, and rotating shaft 9 is bolted to connection together by metallic bond and chassis 4.
The utility model has been owing to installed ball in spiral distribution at the inwall of shaping mould sleeve, and its helical angle is consistent with the helical angle of the spiral welded pipe of manufacturing.Therefore, the band steel is to carry out spiral forming on ball, this has significantly reduced the frictional resistance of forming process, do not have lubricant pollution, because the dimensional accuracy of sleeve and ball is very high, therefore also just guaranteed the Forming Quality of pipe effectively, worm gear-guaranteed weldquality, thus obtain high-quality thin-walled welding pipe and the compound welded tube of bimetallic.Worm spiral angle controller structure is simple, and the adjusting control of helical angle is accurate, and this has just further guaranteed the accurate of spiral opposite joint.
