The specific embodiment
Figure 3 shows that the structural representation of multiple tube rolling device of the present invention, Figure 4 shows that the B of Fig. 3 is to view, as shown in Figure 3 and 4, multiple tube rolling device comprises: pull bar 6, roller 5, a plurality of needle rollers 51, bearing 52, swivel joint 61 and hydraulic cylinder 7.
Figure 5 shows that the working state schematic representation of multiple tube rolling device of the present invention, Figure 6 shows that the C of Fig. 5 is to view, as shown in Figures 3 to 6.Multiple tube is inserted in by internal lining pipe 4 that parent pipe 3 is interior to be formed.5 one-tenth, roller is cylindric, and the inner side of its hollow is arranged with bearing 52.Bearing 52 is arranged on pull bar 6, so that roller 5 circumferentially rotating freely of pull bars 6 relatively.With reference to figure 5, a plurality of needle rollers 51 are arranged on the face of cylinder of roller 5, there is certain angle in the axis of the axis of needle roller 51 and pull bar 6, so that in the process that pull bar 6 moves along the inwall of internal lining pipe 4, between a plurality of needle rollers 51 and the inwall of internal lining pipe 4, produce tangential forces, roller 5 is rotated around pull bar 6.
Figure 7 shows that the cutaway view of swivel joint, with further reference to Fig. 3, Fig. 5 and Fig. 7, between pull bar 6 and hydraulic cylinder 7, by swivel joint 61, be connected.One end cylinder lever connecting rod 6 of swivel joint 61, the piston rod 71 of other end connecting fluid cylinder pressure 7.Swivel joint 61 inside are fixed with bearing 62 and bearing 63.Swivel joint 61 is sheathed on the end of pull bar 6 by a plurality of screws 64, and fixing, to regulate the play of bearing 62 and bearing 63.The piston rod 71 of hydraulic cylinder 7 is sheathed in bearing 62 and bearing 63, and can rotate relative to bearing 62 and bearing 63, also just can eliminate pull bar 6 in the inwall moving process along internal lining pipe 4, the effect of the friction revolving force that hydraulic cylinder 7 produces due to the rotation of roller 5.And the relative swivel joint 61 of pull bar 6 is fixing, the piston rod 71 of hydraulic cylinder 7 moves vertically with pushing drawing rod 6.Hydraulic cylinder 7 can be fixed on basis or miscellaneous equipment.
Figure 8 shows that the enlarged drawing of the roller portion of multiple tube rolling device, shown in figure 8, between the axis of needle roller 51 and the axis of pull bar 6, there is angle a.The scope of angle a is for being more than or equal to 15 degree and being less than or equal to 45 degree.
For another embodiment, with reference to figure 8, the outside that a plurality of needle rollers 51 prolong roller 5 is spacedly distributed.
In addition, the hydraulic cylinder 7 in above-described embodiment also can adopt other power set to substitute according to no situation, for example, and by a cylinder replacement liquid cylinder pressure 7.
Work engineering in conjunction with Fig. 3-7 summary multiple tube rolling device one embodiment.Internal lining pipe 4 and parent pipe 3 can be steel pipe.During production, first lined steel pipe 4 is inserted in parent steel pipe 3, forms composite steel tube; By hydraulic cylinder 7, roller 5 is pushed away to (or drawing) from the tube head of composite steel tube again and enter in lined steel pipe 4, by hydraulic cylinder 7, push away (or drawing) moving roller 5 that makes external diameter be slightly larger than composite steel tube internal diameter and therefrom pass through.Because needle roller 51 is (being the angle of above-described embodiment) being in tilted layout on roller 5, so roller 5 can, along with pulling the size of speed to rotate in helix mode in the drawing process of hydraulic cylinder 7, reach the object of advancing in roller 5 rotation limits, limit.By roller 5 in the interior movement of lined steel pipe 4, thereby make lined steel pipe 4 by plastic deformation, be close to parent steel pipe 3 inwalls more closely, thereby realized the object of even roll extrusion internal lining pipe 4.
In sum, the rolling device of the composite steel tube of above-described embodiment relies on the tangential component of the frictional force of inclination needle roller and lined steel pipe inwall to make roller rotation, substitute the method for use motor rotating rod in the past, make only bearing tension and do not bear shearing force of pull bar, both save the energy, improved again the stress of pull bar.With the pulling force of hydraulic cylinder, replace existing motor rotary driving force.The frictional force of needle roller and lined steel pipe inwall, can reach the object that advance in rotation limit in roller limit in process of production, can strengthen the expanded support power of needle roller, thereby makes lined steel pipe by plastic deformation, be close to parent steel pipe inner wall more closely.Can improve the quality of composite steel tube, solve the problem that pull bar easily twists off in rotation process, improve production efficiency, and reduce the cost of manufacture of composite steel tube.
Although described the present invention with reference to several exemplary embodiments, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because can specifically implementing in a variety of forms, the present invention do not depart from spirit of the present invention or essence, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claims, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be claims and contain.
