Abstract
A housingless roll stand has parallel first and second rolls extending transversely with respect to the mill pass line. The roll ends of the first roll are journalled for rotation in bearings contained in first chock assemblies and the roll ends of the second roll are journalled for rotation in bearings contained in second chock assemblies. Each of the first chock assemblies is arranged adjacent to a second chock assembly on a respective side of the mill pass line. Pairs of identically configured screw shafts interconnect each of the first chock assemblies to the adjacent second chock assembly. The screw shafts each have a first threaded section threadedly engaged with the respective first chock assembly and an opposite hand second threaded section threadedly engaged with the respective second chock assembly. The screw shafts are simultaneosly rotated to effect roll parting adjustments.
Description
The present invention relates generally to rolling mill, relates more specifically to be used for to regulate the improvement system of the roll parting between the roll of so-called " no frame support ".
In traditional no frame support, axle journal is made so that rotate in the bearing in the roll bearing holder assembly in the two ends of a pair roller, and each roll bearing holder assembly of the every side of mill stand is interconnected by the screw rod that bears the roll separating force in pairs when rolling.Screw rod has the reverse thread section in pairs, and backward rotation is so that carry out the roll gap adjustment between roll.
A problem of running in the known no frame support is to need two to construct different screw rods to form the cheek on the every side of mill stand.Such as, in a horizontal milling train, a screw rod typically has left hand thread segment and the right-hand thread section that combines with the top and bottom rolls bearing block assembly respectively, and another screw rod then has respectively right-hand thread section and the left hand thread segment with the combination of identical roll bearing holder assembly.Owing to need heteroid screw rod, unnecessarily increased the complexity of maintenance process, also increased stock's spending of parts simultaneously greatly.
Also have a problem to be in the traditional design, screw rod is driven by unnecessary complex drive mechanism so, and this driving mechanism comprises very big gear-box, and they make and enter the mill stand inconvenience, have also disturbed the compact support space along the milling train operating path.
An object of the present invention is to provide a kind of improved no frame support, wherein roll gap is controlled by a pair of screw rod with same configuration that is installed on the every side of milling train operating path.
Another object of the present invention be simplify be used for drive screw driving mechanism and reduce its appearance and size.
According to the present invention, the no frame mill stand has a pair of first and second rolls with respect to the horizontal expansion of milling train operating path.The roller end of first roll is made axle journal so that rotate in the bearing in the first roll bearing holder assembly is housed, and the roller end of second roll is made axle journal similarly so that rotate in the bearing in being contained in the second roll bearing holder assembly.Each first roll bearing holder assembly is mutually close with the one second roll bearing holder assembly that is positioned at each side of milling train operating path.The full screw rod together of structure interconnects the first and second close roll bearing holder assemblies.Each screw rod has first thread segment that combines with each first roll bearing holder assembly screw thread and second thread segment that combines with each second roll bearing holder assembly screw thread.With drive system every pair of screw rod is rotated simultaneously along same direction, thereby carry out the roll gap adjustment.
Preferably, every pair of screw rod fixes by the supporting of the frame spare between the adjacent first and second roll bearing holder assemblies and with frame spare rotationally.The supporting of frame spare also is fixed on the pedestal that is positioned at both sides, rolling path movably.
The drive system that is used for carrying out the roll gap adjustment preferably includes the pinion that is loaded on each screw rod.The pinion of every pair of screw rod is meshed with placing the 3rd pinion therebetween, and a worm gear is coaxial and fixing rotationally with it with each third pinion.The worm screw that each worm gear and is positioned on the public rotating driveshaft is meshed.
Fig. 1 is the front view of the embodiment of no frame mill stand of the present invention;
Fig. 2 is the side view of mill stand among Fig. 1, and for showing inner each parts better, the part of front supporting base, roll bearing holder assembly and frame spare is broken away;
Fig. 3 is the top view of mill stand illustrated in figures 1 and 2;
Fig. 4 is that the roll bearing holder assembly dots along the cutaway view of 4-4 line among Fig. 3;
Fig. 5 is the cutaway view along 5-5 line among Fig. 4;
Fig. 6 is the schematic three dimensional views of each screw rod and each associated drives mechanism.
Now please referring to accompanying drawing, no frame mill stand of the present invention is shown in 10 places.Mill stand comprises along the first and second parallel rolls 12,14 with respect to milling train operating path P horizontal expansion.The roller end of first roll 12 is made axle journal so that rotate in the bearing 16 in being contained in the first roll bearing holder assembly 18, and the roller end of second roll 14 is made axle journal similarly so that rotate in the bearing 16 in being contained in the second roll bearing holder assembly 20.
Each first roll bearing holder assembly 18 is near the second roll bearing holder assembly 20 that is positioned on the operating path P respective side.The first and second adjacent bearing block assemblies are interconnected by the identical screw rod 12 of a pair of structure.Each screw rod comprises the left hand thread segment 22a on a top, the cylindrical section 22b of a centre and the right-hand thread section 22c of a bottom.
The left hand thread segment on top combines with left hand nut 24 screw threads that are positioned at the first roll bearing holder assembly 18, and the right-hand thread section combines with right hand nut 26 screw threads that are positioned at the second roll bearing holder assembly 20 similarly.Thereby middle circle shell of column 22b fixes vertically and makes axle journal and rotate in frame spare 28 with respect to frame spare 28.Frame spare itself is bearing on the supporting base 30, and is fixed on removably on the pedestal 30 by swivel bolt 32.
Any gap between thread screw section 22a, 22c and their respective nut 24,26 is eliminated by the hydraulic piston cylinder mechanism 34 that extension and its two ends between first and second roll bearing holder assembly 18,20 are connected in bearing block assembly 18,20.
Each screw rod 22 upwards protrudes into one of two gear-boxes 36, and a pinion 38 is arranged in the gear-box 36.The pinion 38 of every pair of screw rod is meshed with a third pinion 40 on the minor axis 42 between them and in the middle of being supported on.One worm gear 44 is positioned at each above the third pinion 40, and is connected to minor axis 42 and rotation together with key or other modes.
Regulate roll gap between the roll 12,14 by rotating driveshaft 48 along clockwise direction or counterclockwise, this depends on wants separately that roll still will close roll.The separating force that is applied by fluid power piston rod mechanism 34 is surmounted by the power that the screw rod on the roll bearing holder assembly 18,20 22 produces.
Because each screw rod 22 all along same direction rotation, therefore can be made identical structure,, has the rightabout thread segment of aligned identical that is.This has simplified maintenance, and has reduced inventory cost to greatest extent.
The transmission arrangements that drives each screw rod 22 makes the size of gear-box 36 reach minimum, thereby helps along each mill stand of milling train operating path close at interval.More particularly, as shown in Figure 6, with the benchmark of the distance C between the right axis of each screw rod as size, the width W of each gear-box 36 approximates C/2, and length L is about 3C/2.This cramped construction also has advantage, that is, the zone that is positioned at above the roll neatly makes the operator enough reach easily, thereby is convenient to maintenance.
