Description
The utility model belongs to the rolling machinery technical field.
The technical background that the utility model produces is, carrying the coil of wire that is transferred on the cold roller-way of control at present high speed hot rolling wire production line with the coil of wire is to do translational motion basically, this motion mode can not change overlapped points between each circle of the coil of wire and the stacking states on roller-way, thereby also just can not realize the even cooling of the coil of wire.
Mo Gen-Xi mark company carries the air feed system of the cold roller-way of control bottom at high speed hot rolling wire production line with the coil of wire, has developed an a kind of air quantity distributor (seeing Figure 13) that is called as Optiflex.It is divided into three parts to the air quantity from the roller-way bottom by coil of wire bulk density difference, in the hope of make coil of wire cooling evenly as far as possible.
The weak point of original technology is, when the coil of wire that is the volume state that looses cools off on roller-way, only does translational motion, but the density degree of piling up because of the coil of wire differs, and can not change the overlapped points of coil of wire centre circle and circle,, cause wire rod performance inequality so caused the serious uneven present situation of coil of wire heat radiation.Although the Optiflex device can solve air quantity assignment problem on the zones of different.But its air quantity allocation result does not also meet the rule of coil of wire bulk density on roller-way, thereby this device fail fundamentally to solve problem of coil of wire inhomogeneous cooling.
The purpose of this utility model is that a kind of high speed hot rolling wire production line of design is carried the cold roller-way of control with coil of wire rotation.This roller-way can force the coil of wire of operation thereon, moves in the mode that advance in the limit, the limit rotates, and continuously changes each point relative overlapped points between each circle of the residing lateral attitude and the coil of wire on the roller-way on the coil of wire thereby reach, and realizes the even cooling of the coil of wire.
The high speed hot rolling wire production line that this utility model provides carries the technical scheme of the cold roller-way of control (seeing Fig. 1 and Fig. 2) to be with coil of wire rotation: comprise parts such as motor, gear-box, fixed support, travel(l)ing rest, travel(l)ing rest position regulator, Hooks coupling universal coupling, the roller that is the truncated cone-shaped body of roll, automatic aligning type rolling bearing, straight hole bearing block and spherical pore bearing block.Every group of roller-way is by gear-box with a plurality of output shafts of a Motor Drive, and each output shaft of this gear-box drives a roller with truncated cone-shaped body of roll separately through Hooks coupling universal coupling.Automatic aligning type rolling bearing is installed on the bearing position at roller axle two ends, and it is installed in the hole of spherical interior cover.The spherical interior cover of one end is installed in the spherical pore bearing block of transmission side; Cover is installed in the hole that places the dissection type spacer shell part in the non-transmission side straight hole bearing block in the other end spherical, the straight hole bearing block of this non-transmission side be installed in travel(l)ing rest above.Below travel(l)ing rest, be provided with the travel(l)ing rest position regulator.This adjusting device or the pinion and rack that constitutes by tooth bar and the gear meshing that is installed on the rail chair that is cemented on the travel(l)ing rest, the adjustment torque that it adds is applied on the gear shaft; Or being cemented in the nut on the rail chair and the screw mechanism of the leading screw of the axial constraint that cooperates with it and be subjected to travel(l)ing rest, the adjustment torque that it adds is applied on the leading screw; It can also be other linear moving apparatus.So just formed the travel(l)ing rest position regulator that can on rail chair, slide.
On the cold roller-way of control, the linear differential that the truncated cone-shaped roller diameter difference of utilization rotation produces on roll surface forces the coil of wire that is transported to move in the mode that advance in the limit, the limit rotates on roller-way.For moving on the center line longitudinally along roller-way all the time at the center that guarantees each circle of the coil of wire, vertically move travel(l)ing rest by regulating the travel(l)ing rest position regulator, roller center line and gearbox output shaft axis angle are changed, realize that control line twists in the requirement of the sideslip on the roller-way.The key that the angle of cut of roller and gear-box is adjusted arbitrarily within the specific limits, one is to have adopted Hooks coupling universal coupling, to guarantee the transmission of power under the angular displacement condition between the connected piece; Another is to have adopted the travel(l)ing rest position regulator.
The beneficial effects of the utility model are to have utilized the diameter of the truncated cone-shaped body of roll poor, when roller rotates, along the linear differential that has on the roll surface length direction, just forced the coil of wire to do the action that limit rotation, limit are advanced, and can change on the overlapped points between each circle of the coil of wire and the coil of wire any point constantly in roller-way position transversely.Thereby the even cooling that has realized the coil of wire is no longer dependent on the situation that air quantity distributes.
Organic assembling with bearing block, Hooks coupling universal coupling and travel(l)ing rest position regulator of self-alignment, realized that the rollgang roller inclination adjusts arbitrarily in the angle that the Hooks coupling universal coupling inclination angle allows, thus can guarantee that the coil of wire moves on roller-way to neutrality.This coil of wire rotation carries the cold roller-way of control to compare with Mo Gen-Xi mark's Optiflcx device, not only has characteristics simple in structure, cheap, easy and simple to handle, and main is that coil of wire cooling is very even, and is no longer dependent on the distribution condition of wind supply quantity.

High speed hot rolling wire production line carries the cold roller-way of control to be located at the Laying head back of high-speed wire production line with coil of wire rotation, is used for substituting the cold rollgang of existing diffusing volume cooling control.This device structure and characteristics division thereof are as follows.
Whole roller-way as depicted in figs. 1 and 2.Comprise that the motor (7) as power source provides power, gear-box to have a plurality of output shafts to gear-box (6), each output shaft drags a roller (2) with truncated cone-shaped body of roll by Hooks coupling universal coupling (5), forms the type of belt drive of collective's transmission.The driving end of roller is installed on the fixed support (4) by spherical pore bearing block (3), and its non-transmision end is installed on the travel(l)ing rest (11) by straight hole bearing block (1).Utilize the linear differential that the diameter difference on the body of roll produces when rotating, force the coil of wire (8) on it to do the motion that the limit rotates, advance in the limit, thereby realized the even cooling purpose of the coil of wire.Because coefficient of friction can exist difference between the mutual traction action under the different condition between each circle of the coil of wire and the roller-way and the coil of wire, meeting disalignment (9) when the unavoidable coil of wire travels forward on roller-way, so must adjust angle (α angle) between truncated cone-shaped roller axis and gearbox output shaft axis easily and accurately, so that the deviation phenomenon when can strictness controlling the coil of wire and advancing.Control for deviation phenomenon, or utilize pinion and-rack travel(l)ing rest position regulator (12) under the travel(l)ing rest, or utilize spiral travel(l)ing rest position regulator (10), realize that travel(l)ing rest vertically moves a segment distance forward or backward along rail chair (13).The application of standard component Hooks coupling universal coupling has solved the transmission of power problem when roller tilts.
The assembly relation of roller-way assembly as shown in Figure 3.The roller (16) of frame on fixed support (15) and travel(l)ing rest (17) installed automatic aligning type rolling bearing (25) on its two side shaft positions, and rolling bearing is contained in the hole of the spherical interior cover (14) with spherical outer surface.But overlap in spherical in spherical pore bearing block (23) hole that then is contained in the transmission side dissection type respectively and in the spherical inner hole of dissection type spacer shell (20).And the dissection type spacer shell with connecting bolt (18) fixed be one after, the mode with matched in clearance has been contained in the straight hole of straight hole bearing block (21) again.Use bearing block connecting bolt (22) that the loam cake and the base of above-mentioned two bearing blocks are connected to together at last again, and they are installed in respectively on fixed support and the travel(l)ing rest with bearing block foundation bolt (24).When travel(l)ing rest when rail chair vertically moves, on the roller axle that tilts axial float takes place in order not make bearing inner race, should allow that cover in axial direction moves with the straight hole bearing block in the non-transmission side sphere.Between has been set up the dissection type spacer shell for this reason.So just constituted the axial restraint of roller, the design feature of non-transmision end retractable at driving end.Guaranteed when roller tilts in thermal expansion with because of roller that freely stretching under the factors such as variation appears in its two end axles bearing centre-to-centre spacing, also made this bearing have the characteristics of self-alignment, the service life of having improved roller bearing.Simultaneously, also allow can operate as normal under certain angular displacement (α angle) condition between the center line of roller axis and spherical pore bearing block and straight hole bearing block for this structure.The sealing of both sides bearing chamber is cemented in lid (26) and end cap (19) thoroughly to overlap on two side end faces in spherical with screw and realizes.
The structure of spherical pore bearing block, straight hole bearing block, spherical interior cover and dissection type spacer shell such as Fig. 4～shown in Figure 11.The inner ring of the rolling bearing on the roller axle is contained in respectively on the bearing position of roller two side shafts with the form of interference fit.The outer ring of rolling bearing is contained in the hole of the spherical interior cover (34) with spherical outer surface.Cover is contained in gap fiting mode in the spherical pore of base (28) composition of the loam cake (27) of spherical pore bearing block of transmission side and spherical pore bearing block in sphere.Another spherical interior cover is contained in two and half of dissection type spacer shell (35 and 36) with gap fiting mode equally and overlaps in the spherical inner hole of forming, dissection type spacer shell (37) is fixed with connecting bolt to be one, and then with gap fiting mode it is contained in the hole of base (31) of the loam cake (30) of non-transmision end straight hole bearing block and straight hole bearing block.It is whole going up of two bearing blocks being somebody's turn to do fixed with base respectively with connecting bolt at last.
When the coil of wire to be cooled entered this rollgang, because the linear differential of truncated cone-shaped roller surfaces, the mode that forces the coil of wire to advance with limit rotation, limit was moved.This method of operation can change the overlapped points between each circle of the coil of wire effectively constantly.Under suitable roller-way inclination angle condition, the central point of every circle moves along the roller-way center line all the time on the coil of wire.Continuous variation has also taken place in the transversely residing position of roller-way in the arbitrfary point on the coil of wire simultaneously, is promptly moved by a side direction opposite side.Fundamentally solved the phenomenon of present ubiquitous coil of wire inhomogeneous cooling.
