The utility model content
The main purpose of the utility model is to overcome the above-mentioned shortcoming of existing product technology; And a kind of boxing turning rolls is provided, it is simple to operate, in the tube-making process process; Support and drive the pipeline rotation, cooperate the multiplewire submerged arc welding machine to accomplish welding the outer circumferential weld of pipeline enclosure, interior longitudinal joint and outer longitudinal joint; Enlarge the control range of pipeline welding speed, not only had very strong shock resistance; And, stable in welding process, improved the precision and the welding quality of the pipeline speed of service; Simultaneously, the utility model can adapt to the pipeline of different-diameter, has improved welding efficiency.
The purpose of the utility model is realized by following technical scheme:
A kind of boxing turning rolls; Be provided with an active roller frame base and a return idler frame base; Active roller frame base and return idler frame base keep at a certain distance away and place relatively; Be separately installed with active roller and return idler on an active roller frame base and the return idler frame base, active roller is installed on the motor; It is characterized in that: keep at a certain distance away on active roller frame base and the return idler frame base and arrange the bolt hole that several are used to regulate distance between driving and driven roller two rollers respectively, it is right that adjusting bolt and nut are installed in the hole.
Said motor is the AC servo motor that has encoder close-loop feedback control device, and AC servo motor links to each other with double-contracting network turbine and worm gearbox.
Said active roller and return idler adopt polyurethane roller, and bearing is equipped with in inside.
Connect as one through the pipeline that is installed between active roller and the return idler between said active roller frame base and the return idler frame base.
The beneficial effect of the utility model: the utility model is simple to operate, owing to the spacing between two main drive wheels can be regulated, goes for the variation of any pipe diameter size, makes it when changing pipeline, can not receive the restriction of pipe diameter size; And stable, have very strong shock resistance; In the tube-making process process, support and drive the pipeline rotation, cooperate the multiplewire submerged arc welding machine to accomplish welding to the outer circumferential weld of pipeline enclosure, interior longitudinal joint and outer longitudinal joint; Multiplewire submerged arc welding motor speeds control range, welding procedure quality and production efficiency have been promoted.

Main label declaration among the figure:
1. AC servo motor, 2 active rollers, 3 active roller frame bases, 4 return idlers, 5 return idler frame bases, 6 double-contracting network turbine and worm gearboxes.
The specific embodiment
Like Fig. 1-shown in Figure 7, the utility model mainly by: active roller frame AC servo motor 1, active roller 2, active roller frame base 3, return idler 4, return idler frame base 5, double-contracting network turbine and worm gearbox 6 are formed.Wherein, active roller frame AC servo motor 1, active roller 2, linking to each other with active roller frame base 3 with bolt connecting mode constitutes the active roller frame; Double-contracting network turbine and worm gearbox 6 links to each other with active roller frame AC servo motor 1 with the keyway connected mode.Return idler 4 links to each other with return idler frame base 5 with bolt connecting mode, constitutes the return idler frame.Active roller frame base 3 and return idler frame base 5 keep at a certain distance away and place relatively.Active roller 2 and return idler 4 adopt polyurethane roller, and bearing is equipped with in its inside.Active roller frame base 3; Return idler frame base 5 weight capacities are respectively up to 15 tons; Keep at a certain distance away on active roller frame base 3 and the return idler frame base 5 and arrange the bolt hole that several are used to regulate 2,4 distances of driving and driven roller respectively, it is right that adjusting bolt and nut are installed in the hole.When the distance of 2,4 on two driving and driven rollers needs adjustment; The bolts and nuts that unload current bolt hole with spanner are right; Then move and again bolt is inserted the nut of screwing in the corresponding bolt hole after driving and driven roller 2,4 is adjusted distance; Thereby the distance that realizes 2,4 on two driving and driven rollers can be adjusted, and reaches to be fit to pipe diameter scope 900-3000mm.Active roller frame and return idler frame link to each other with AC servo motor 1 through double-contracting network turbine and worm gearbox, and 2 groups of double-contracting network turbine and worm gearboxes 6 link to each other with active roller 2 through connecting axle.Link to each other with servomotor 1 through double-contracting network turbine and worm gearbox 6, strengthened the ability of moment carrying, safer when work is produced.The effect of active roller frame is to drive to be soldered pipeline and to rotate, to accomplish weld seam centering; The return idler frame has been the effect that supplemental support is soldered pipeline.
