The specific embodiment
Shown in Fig. 2 a, 2b, be respectively the utility model embodiment described welding compression roller front view and side view.With regard to its structure, adopt planer-type frame 201 to guarantee whole rigidity.Two pairs of cross rolls 203 replace vertical roller about employing, replace two little cross rolls with one group of coaxial top roller 204 again, and the closed type of Zu Chenging can well apply upset force to the pipe that is heated to welding temperature continuously thus.In addition, be used for two semi-circular bracket 301 of the upper right lower roll of carries left respectively, being installed in two fan-shaped gate bearings 202 of symmetry, and that fan-shaped gate bearing 202 can be independent or paired swinging around its door-hinge 402 are to finish the adjustment of 205 pairs of steel pipe amount of compression of all roller regulating devices of ring.Simultaneously, a pair of top roller 204 can be in vertical motion by hydraulic cylinder 508, depresses fast or lifts to finish.Top roller adjusting device 204 can be carried out electronic adjustment of drafts or manual fine-tuning by elevating mechanism 503.
By above-mentioned installation and adjustment, very reliable and realized control easily to steel pipe geometry and upset force, thus guaranteed the quality of weld seam.
In addition, since adopted about, about four rollers than minor diameter, this has just strengthened the nip angle of steel pipe, thereby has improved the direction of extruding force, promptly reduced idle axial force and improved meritorious radially and peripheral force, the upset force of unit are is improved.Equally, owing to cancelled larger-size two vertical rollers, make the required space of high-frequency heating obtain very big improvement, the induction coil (or leg) of heating usefulness can more close meeting point.Thereby guaranteed best " kindred effect ", improved speed of welding.
As shown in Figure 3, be all roller arrangement structure charts of the described ring of the utility model embodiment.By the shifting fork device 406 drive bearing pins 303 that are installed on the fan-shaped gate bearing 403 all roller assemblings 302 of semi-circular bracket 301 drive rings are rotated around the pipe fitting center, thus the geometry of adjustment pipe fitting.By adjusting skewback 304 and screw 305 all roller assemblings 302 of ring are moved radially, thereby adjust the geometry and the amount of compression of pipe fitting, simultaneously, also make and the reparation increased frequency of roller improved utilization rate, reduce cost.The welding compression roller of this kind annular array, having ready conditions is designed to " apple shape " with its pass that closes up, and promptly the steel pipe of welded condition is the bigger and level and smooth geometry in top, makes its weld seam stress the best.In addition, when producing the different size steel pipe, can realize quick replacing.
Shown in Fig. 4 a, 4b, 4c, be respectively all roller regulating device vertical views of the described ring of the utility model embodiment, front view, side view.The adjustment process of all rollers of ring is among the figure: contained most skelp by the ring week roller assembling 302 that left part upper and lower roll and right part upper and lower roll are formed, played when drawing the joint close effect in, also the weld seam that is heated to welding temperature has been applied upset force.Because left and right sides two parts are installed in the fan-shaped gate bearing 403 separately.And two fan-shaped gate bearings 403 are separately around its door-hinge 402 swings, the size that bearing folding adjusting device 401 changes amplitude of fluctuation can be adjusted the radial distance of all roller assemblings 302 of ring, thereby realized contraction (increasing upset force) and loose (reducing upset force), controlled the shape and the amount of compression of welded tube thus skelp.
About the swing of two fan-shaped gate bearings 403, by manual adjustment worm-gear speed reducer 405 drive screw mandrel 407, screw 408 is realized.Two fan doors can be swung synchronously, can revise separately again, and itself again a force-increasing mechanism for compression roller.Because reductor 405 is worm gear devices, so fan-shaped gate can be by locking device 404 self-lockings after swinging to suitable position.
Shown in Fig. 5 a, 5b, 5c, be respectively the described top roller adjusting device of the utility model embodiment side view, front view, vertical view.The process of the adjustment of top roller is among the figure: top roller above steel pipe seam, by about two roller sheets and middle spacer sleeve form.Its installation site and four all rollers of ring are on the same cross section, and its effect is to compress steel pipe and be the weld seam guiding.
Whole top roller device 506 links by hinge and front-slider 509, links by swing arm 505 and rear slider 510.Forward and backward slide has motor 501, clutch 502, connecting rod 507, lift 503, front-slider 509, rear slider 510 to realize moving up and down respectively, satisfies the requirement of top roller differing heights.In addition, top roller can also be realized depressing fast or lifting by the hydraulic cylinder 508 on its top, and can be by manual regulating device 504 fine settings.After adjusting the position, the control by hydraulic lock can guarantee the constant of weld seam force value.Above-mentioned top roller adjusting device can effectively prevent the generation of " peach shape point " defectives such as " mismatch ", has guaranteed the quality of weld seam.
