Concrete, the flexible guide and guards of the adaptive double speed of width of what the utility model provided be applied to mill, leading screw processed by alloy wrought steel and left-handed coarse pitch section A (can match with the internal thread of left-handed coarse pitch nut 2) can be divided into by machining feature, left optical axis section B, left-handed fine pitch section C(can match with the internal thread of left-handed fine pitch nut 5), central segment G, dextrorotation fine pitch section D(can match with the internal thread of dextrorotation fine pitch nut 7), right optical axis section E and dextrorotation coarse pitch section F(can match with the internal thread of dextrorotation coarse pitch nut 8).As shown in Figure 5, the version of left-handed fine pitch nut 5, dextrorotation fine pitch nut 7 as shown in Figure 6 for the version of left-handed coarse pitch nut 2, dextrorotation coarse pitch nut 8.
In first axle sleeve 3 of left-handed coarse pitch nut 2 and left-handed fine pitch nut 5 embedding operation side M and by screw closing, in the second axle sleeve 14 that dextrorotation fine pitch nut 7 and dextrorotation coarse pitch nut 8 embed transmission side N and by screw closing, the diameter of bore of the first axle sleeve 3 and the second axle sleeve 14 is greater than the left optical axis section B of leading screw 6 and the external diameter of right optical axis section E, is not in contact with it, in order to prevent injuring screw thread when installation and greatest limit position, and left-handed coarse pitch nut 2 and left-handed fine pitch nut 5 do not allow to engage simultaneously, dextrorotation fine pitch nut 7 and dextrorotation coarse pitch nut 8 do not allow to engage simultaneously, therefore the left-handed coarse pitch section A of leading screw 6 and the large footpath of dextrorotation coarse pitch section F are less than the path of left-handed fine pitch nut 5 and dextrorotation fine pitch nut 7 respectively, do not come in contact each other, left-handed coarse pitch nut 2, the path of dextrorotation coarse pitch nut 8 is all greater than left optical axis section B, the diameter of right optical axis section E, do not come in contact each other, left-handed fine pitch nut 5, the path of dextrorotation fine pitch nut 7 is greater than central segment G, left optical axis section B, the diameter of right optical axis section E, do not come in contact each other.
The welding support body of the first axle sleeve 3 and the first deflector roll seat 15 is by the seam along rolling direction with location and together with being put together on by king-bolt, the welding support body of the second axle sleeve 14 and the second deflector roll seat 16 is by the seam along rolling direction with location and together with being put together on by king-bolt, guide rail bracket 12 to be connected with transmission side bearing block 10 by the three-dimensional seam of U-shaped and fore side bearing block 1 and realize its level to vertical accurate location, as shown in Figure 4.
One end of leading screw 6 is arranged in fore side bearing block 1 by little rolling bearing, the other end of leading screw 6 by the output shaft of shaft coupling 9 and motor 11 in level to connecting as one, shaft coupling 9 is arranged in transmission side bearing block 10 by large-diameter roller bearing, together with motor 11 to be put together on screw after being located by circular seam with transmission side bearing block 10.Before fore side bearing block 1 and transmission side bearing block 10 put together on machine by screw after device or machine device support body on and join and make alignment pin.
Operation principle of the present utility model is:
During original state, deflector roll 4 is in most wide limits position, leading screw 6 and left-handed coarse pitch nut 2 and dextrorotation coarse pitch nut 8 form left-handed steep-pitch thread pair and dextrorotation steep-pitch thread pair respectively, and leading screw 6 does not contact with dextrorotation fine pitch nut 7 with left-handed fine pitch nut 5, as shown in Figure 1.
As shown in Figure 2, when band proceeds to this guide and guards, motor 11 starts and drives leading screw 6 that low speed occurs by shaft coupling 9 and rotates stably, leading screw 6 provides to left-handed coarse pitch nut 2 and dextrorotation coarse pitch nut 8 axial force that size equidirectional is contrary by the effect of left-handed steep-pitch thread pair and the effect of dextrorotation steep-pitch thread pair, and and then the entirety driving the first axle sleeve 3 and the first deflector roll seat 15, second axle sleeve 14 and the second deflector roll seat 16 to form horizontally do move toward one another fast, the first deflector roll seat 15, second deflector roll seat 16 synchronizing close fast.
When deflector roll 4 is 10mm ~ 20mm with the distance of strip side portion, as shown in Figure 2, leading screw 6 is thrown off with left-handed coarse pitch nut 2 and dextrorotation coarse pitch nut 8, and leading screw 6 starts to screw with left-handed fine pitch nut 5 and dextrorotation fine pitch nut 7 and forms left-handed fine pitch screw thread pair and dextrorotation fine pitch screw thread pair respectively simultaneously.Along with the continuation of motor 11 rotates, leading screw 6 provides to left-handed fine pitch nut 5 and dextrorotation fine pitch nut 7 axial force that size equidirectional is contrary by the effect of fine pitch screw thread pair, and and then the entirety driving the first axle sleeve 3 and the first deflector roll seat 15, second axle sleeve 14 and the second deflector roll seat 16 to form horizontally do move toward one another slowly, deflector roll 4 synchronizing close slowly, meanwhile, the first deflector roll seat 15, second deflector roll seat 16 center line band being pushed to unit slowly.
When band is positioned on unit centre line, motor 11 overflow is also stopped the rotation, and the first deflector roll seat 15, second deflector roll seat 16 no longer changes due to its lateral attitude of self-locking effect of fine pitch screw thread pair.Band moves on and finally completes threading, and guide and guard complete.After threading completes, motor 11 drags leading screw 6 and reverses, and in like manner, leading screw 6 promotes the first deflector roll seat 15, second deflector roll seat 16 by the effect of fine pitch screw thread pair and horizontally opens slowly.When leading screw 6 is thrown off with left-handed fine pitch nut 5 and dextrorotation fine pitch nut 7, leading screw 6 and left-handed coarse pitch nut 2 and dextrorotation coarse pitch nut 8 start to screw and form the secondary and dextrorotation steep-pitch thread pair of left-handed steep-pitch thread respectively.Along with the continuation of motor 11 rotates, the first deflector roll seat 15, second deflector roll seat 16 is horizontally opened fast and gets back to original state rapidly, waits for threading next time and guide and guard, as shown in Figure 1.
First deflector roll seat 15, second deflector roll seat 16 without the need to being all opened to most wide limits position at every turn, when the specification of blank is close, first deflector roll seat 15, second deflector roll seat 16 can be opened to suitably narrow position, the guide and guard time next time needed for threading will be reduced like this, improve rhythm of production, there is the adaptive characteristic of width, applied range.
Guide rail bracket 12 and adopt the three-dimensional seam of U-shaped to locate between fore side bearing block 1 and transmission side bearing block 10, structure is simple, and maintenance is convenient.
The utility model utilizes the identical screw thread pair of rotation direction phase reverse pitch to realize stable synchronously the opening and closing of deflector roll, remotely adopt steep-pitch thread secondary from strip side portion, fine pitch screw thread pair is adopted more nearby from strip side portion, non-maintaining self-lubricating bearing is installed at deflector roll place, arranges suitable oil pressure relief for CD-ROM drive motor.The utility model rhythm of production is high, the large flexible contact of low speed, and environmental protection and range of application are large, and structure is simple, convenient operation and maintenance.
