Planetary web roll rotating hub type flattening machine
Technical field
The utility model relates to a kind of straightener of planet cross roll rotary hub type strengthening round section equipment, particularly a kind of ultralong thin walled metal pipe material.
Background technology
Present cross roll rotary hub type strengthening round section machine both domestic and external all is by commentaries on classics hub that a plurality of passive smoothing rolls are housed and preceding pinch roll basically, back pinch roll is formed, such structure has certain restriction to strengthening round section, particularly when thin-wall pipes is aligned, if straightening force applies too big, at first the phenomenon that tubing is crushed can appear, secondly, when being subjected to bigger straightening force in the commentaries on classics hub, workpiece does the time spent, will inevitably produce very big with torque, pinch roll is difficult to eliminate and is somebody's turn to do with torque before and after relying on, in case and workpiece produces in the aligning process with commentaries on classics, then straightening quality just can not get guaranteeing, and workpiece is abnormally dangerous in operating process with the whipping phenomenon that commentaries on classics causes.Too little as straightening force, though eliminated, can not reach desired flattening precision, because guarantee the primary condition of straightening quality with changeing phenomenon, be to make the workpiece plastic deformation that its each cross section can both obtain uniformly, the degree of depth is enough after by straightener, and align required recurvation distortion.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of can effectively eliminate by the set round material with change phenomenon and can improve greatly smoothing roll with by the contacting and the press-bending state of set round material, help to improve the linearity aligned by the set round material and the planetary web roll rotating hub type flattening machine of circularity.
The purpose of this utility model is achieved through the following technical solutions:
A kind of planetary web roll rotating hub type flattening machine, be characterized in comprising and change hub and drive first Power Drive Unit that changes the hub rotation, be installed on second Power Drive Unit that changes at least two group smoothing rolls in the hub and drive each smoothing roll rotation, the upper and lower smoothing roll of wherein respectively organizing smoothing roll is arranged in the both sides of rotation symmetrically, and each smoothing roll is with respect to the certain angle of rotation inclination.
Wherein, above-mentioned first Power Drive Unit is made up of motor and belt pulley.Above-mentioned second Power Drive Unit comprises a plurality of hydraulic motors with the corresponding connection of each smoothing roll difference, and connects by the flexible pipe polyphone between described each hydraulic motor, and two ends are connected with chicksan respectively again.Above-mentioned each smoothing roll that changes in the hub that is installed on can be realized upper and lower moving and left rotation and right rotation by vertical adjusting screw mandrel and level adjusting screw mandrel respectively.
But the utility model is owing to adopt the smoothing roll of rotation and the commentaries on classics hub structure combining of revolution, change the passive smoothing roll that changeed in the past in the hub into initiatively smoothing roll, the rotating speed that changes hub and smoothing roll by coupling with eliminate by the set round material with the commentaries on classics phenomenon, improved smoothing roll with by the contacting and the press-bending state of set round material, help to improve linearity.Guarantee its circularity by smoothing roll clamping by the set round material and around being rolled, be very beneficial for the aligning of ultralong thin walled tubing by the set round material by fluid motor-driven.Simultaneously, the adjustment parameter that changes hub rotating speed and smoothing roll rotating speed coupling can be adjusted by the flow of rotating speed of motor and hydraulic motor easily.
Describe basic composition of the present utility model and operation principle in detail below in conjunction with accompanying drawing.

The specific embodiment
As Fig. 1~shown in Figure 2, planet cross roll rotary hub type strengthening round section machine described in the utility model adopts changes that hub 5 rotates and smoothing roll 3 rotations and by the non-rotary method for aligning of set round material, comprise and change hub 5 and drive first Power Drive Unit that changes hub 5 rotations, be installed on second Power Drive Unit that changes at least two group smoothing rolls 3 in the hub 5 and drive each smoothing roll 3 rotation, the upper and lower smoothing roll of wherein respectively organizing smoothing roll 3 is arranged in the both sides of rotation symmetrically, and each smoothing roll 3 is with respect to the certain angle of rotation inclination.Wherein, above-mentioned first Power Drive Unit is made up of motor 9 and belt pulley 8.Above-mentioned second Power Drive Unit comprises a plurality of hydraulic motors 7 with the corresponding connection of each smoothing roll 3 difference, and connects by flexible pipe 2 polyphones between described each hydraulic motor 7, and two ends are connected with chicksan 1 respectively again.Above-mentioned each smoothing roll 3 that changes in the hub 5 that is installed on can be realized upper and lower moving and left rotation and right rotation by vertical adjusting screw mandrel 6 and level adjusting screw mandrel 4 respectively.At this moment, changeing hub 5 is two supports, its power resources are first Power Drive Unit, this first Power Drive Unit is passed to by belt pulley 8 by a motor 9 to be changeed on the hub 5, change smoothing roll that at least six symmetrical expressions arrange 3 is housed in the hub 5, at least six smoothing rolls are drive roll, its power resources are second Power Drive Unit, this second Power Drive Unit is the hydraulic motor 7 that links separately, the hydraulic motor of at least six rollers connects by flexible pipe 2 polyphone, and the rotating speed of each smoothing roll is the same when guaranteeing a certain specification.The hydraulic oil that drives the hydraulic motor of smoothing roll rotation is supplied with by chicksan 1.By driving upper-lower position that screw mandrel 6 controls smoothing roll 3 to adapt to the aligning of different-diameter roundwood, be convenient to realize numerical controlization, avoided artificial factor, reach the purpose that infinitely adapts to the roundwood diameter.Simultaneously, in the process of the rise and fall of smoothing roll 3, can also demonstrate the position and the corresponding roundwood diameter of smoothing roll 3 intuitively, help monitoring by dial.Regulate screw mandrel 4 left rotation and right rotation smoothing rolls by level and realize angle adjustment, and dispose the angle that accurate rule shows smoothing roll 3, can make things convenient for and control intuitively the size of feeding component when aligning, and then controlled the speed of aligning.
As shown in Figure 2: the smoothing roll 3 in the commentaries on classics hub 5 is with respect to the certain angle of rotation inclination, and two rows smoothing roll 3 symmetric arrangement, guaranteed to change the dynamic balancing of hub 5, made by the set round material in whole aligning process, to have enough stability, thereby guarantee effectively by the straightening quality of set round material.
