The vertically arranged device method of work of axle is as follows:
Main drive (not expression on the figure) driving cam 24 and 61(Fig. 2 by milling train).Cam 24 is through roller 28, lever 27, reversible protector 13, lever 30 and roll bar 31 crossbeam between the idler pulley 11 9 is moved right, and axle 8(Fig. 3) on cylindrical bearing 16, rotate, half anchor clamps 1 are tightened up, thereby blank 23 is clamped.Cam 24(Fig. 2) profile be designed to 5/6 cycle period (being that positive and negative stroke is when rolling and during feeding) blank all clamped by half anchor clamps 2.Cam 61 profiles are designed to when positive and negative stroke is out of shape, double-arm lever 62 transfixions, and axial rolling force is passed to cam 61 by blank 23 through half anchor clamps 2, frame 69, conduit 4 and lever 62.When feeding, cam 61 moves a feeding pitch through lever 62, conduit 4, frame 69 and half anchor clamps 2 with blank 23.Before blank rotated, cam 24 profiles can make reverse protector 13 be moved to the left together with lever 27,30, roller 28,31 and crossbeam 9.At spring 17(Fig. 3) effect under, axle 8 is rotated on cylindrical bearing 16, half anchor clamps 2 unclamp, and blank 23 is deviate from.This moment, blank 23 began to rotate, and at spring 68(Fig. 2) effect under, frame 69 is got back to the home position with half anchor clamps 2, conduit 4 and 5, levers 62, this is guaranteed by correspondent section on cam 61 profiles.When blank rotated, reverse protector 13 moved right together with lever 27,30, roller 28,31 and crossbeam 9, and finished back (Fig. 3) axle 8 in the blank rotation and rotate on cylindrical bearing 16, tightened up half anchor clamps 2, and the latter clamps blank 23.Circulation subsequently repeats.
Oil infeeds (Fig. 2) in the power cylinder chamber 37, and oil pressure can be regulated, and oil pressure value depends on blank clamping force allowable.When the clamping force in half anchor clamps 2 surpassed, to the active force rising of crossbeam 9 and piston 36, the two was moved to the left under the effect of this power, thereby avoided mechanism's overload, and this is because the gap between half anchor clamps 2 increases, and blank 23 clamping forces stop to increase.
When load was reduced to allowable value, piston 36 was got back to initial position.
The blank clamping force can change, and its measure is adjusting wedge adjuster 12(Fig. 1) the position, change the inclination angle of axle 8, the result has changed the gap between half anchor clamps 2.The blank clamping force can change in the wide range between the maximum allowable value 0.
In addition, the voussoir adjuster 12 that changes axle 8 inclination angles can be used for changing the gap between half anchor clamps 2, thereby with the identical blank of half chuck enforcement diameter deviation in the 5-6% scope
For example diameter can equal identical half pallet feed of blank maximum gauge with the seam road from 56 to 60mm blank.Can reduce half required anchor clamps kind of this device like this.
The convex shoulder 22 of roller 7 sleeves 20 can be made one with sleeve, also can make separately, is pressed on the sleeve subsequently.
Axle 8 is horizontally disposed and clamped the work of the cold tube-rolling mill pay-off of two blanks simultaneously by half anchor clamps 2; the method that also using chats face to face states is implemented; its cam 24(Fig. 6) action is through roller 45, lever 42, and reversible protector 13 flexible members 41 are passed to crossbeam 9.
The adjusting at 8 couples of roll line 0-0 of axle inclination angle moves up or down with voussoir adjuster 12 and realizes; can regulate clamping force so gentlely; the motion closure of the reversible protector riding chain that make with flexible member 41 this moment, the active force of 11 pairs of crossbeams 9 of idler pulley is implemented when acting on axle 8 by spring 17.The power cylinder type protector riding chain closed embodiment similar (Fig. 1,2) that moves.
Flexible member 41(Fig. 6) compress in advance with adjusting nut 57, this power can in very large range be regulated, and its value depends on the given allowable clamping force of half anchor clamps to blank.When exceeding given clamping force allowable, active force to crossbeam 9 and disk 56 increases, the two is under the effect of this power, to spring 41 additional compaction, move right, thus the overload of anti-locking mechanism, because the gap between half anchor clamps 2 increases, actual the stopping of the clamping force of blank 23 increases, and bar 54 inserts in the chamber 59 of crossbeams 9 at this moment.
When load was reduced to allowable value, flexible member 41, disk 56 and crossbeam 9 were got back to initial position.
The adjustment in gap is implemented with screw rod 49 between clamping force and half anchor clamps.This screw rod by motor 75 through worm reducer 76 transmissions.
The adjusting of feeding amount is by screw rod 65(Fig. 5) implement, this screw rod by motor 77 through decelerator 78 transmissions.
In the vertically arranged device of axle, discharge power cylinder chamber 37(Fig. 2) in oil, can stop feeding, this moment, piston rod 29, lever 30, roller 31 and crossbeam 9 were moved to the left.This moment, half anchor clamps unclamped, and did not clamp blank, and device idle running.
In the horizontally disposed device of axle, with voussoir 48(Fig. 6) set-point that moves up, can stop feeding.Half anchor clamps unclamp in this case, no longer clamp blank.
Under first kind of situation, pressure oil infeeded chamber 37(Fig. 2), can begin feeding; Under second kind of situation, make voussoir 48(Fig. 6) recover initial position, can begin feeding.
No matter be to clamp and pay-off, all can in clamping and feeding, realize tube reducing by the blank above-mentioned which kind of scheme realizes.For this reason should be according to Fig. 8 construction joint road 72 on half anchor clamps 2.Zhuan Zhi adjustment and work are undertaken by following mode in this case.By means of voussoir adjuster 12, half anchor clamps 2 are seamlessly installed.
After half anchor clamps are opened, when it got back to initial position, half anchor clamps were with the conical section contact of being out of shape blank, with the angled installation of roll line, and be in contact with one another along the edge with half anchor clamps 2 of radius r rounding, and contact with blank along the sizing reduction section A and the line of demarcation of proofreading and correct section B.Because changeover portion profile radius R is greater than half anchor clamps, 2 edge chamfering radius r, in compression subsequently, close fully when tight at half anchor clamps, promptly proofread and correct section A edges generating line with the blank center line when parallel, seam road 72 contacts blank at the terminal point of proofreading and correct section B and the boundary of proofreading and correct section B and changeover portion C.Therefore can eliminate the local impression of blank fully.
Be worth pointing out in the horizontally disposed device of axle, during simultaneously to two blank tube reducings, to have only with two and half anchor clamps 2(Fig. 5 on the limit of roller 7 contacts) be installed in roll line angled.Therefore when half chuck is got back to initial position, last blank is by the roll line deflection that makes progress, and following blank is then by the roll line downwards, and tilt quantity is 0.5mtg x, m-feeding pitch wherein, tg x-sizing reduction section A tapering.For example when m=20mm and tg x=0.1, it is 1mm that its departure is venerated, and this can not cause destroying technical process.
When blank passed through to close anchor clamps 2, its diameter reduced, and therefore half identical anchor clamps can be used for the feeding that the diameter deviation amount equals the various blanks of diameter reducing area decrement, have from then on reduced required instrument kind number.The blank that is come out by (adjustment) clamping device has the external diameter of correction, and this has improved the condition of work of chuck in the middle of the milling train greatly.
The tube reducing of blank in pay-off can be used to shorten design of section of rolling mill diameter reducing area length, thereby can increase the compressional zone of wall and proofread and correct section, and this can cause improving the production capacity of milling train, because can increase the blank feeding pitch like this.
The cold reduction of tubes machine blank feeder structure that is proposed (no matter axle level or be arranged vertically), compare with known structure, can improve the device functional reliability, prolong high blank pushing precision of critical piece life-span, the result can improve tube rolling speed and increase the blank feeding pitch.
This device also can carry out blank part tube reducing when implementing the blank feeding in addition, so also can increase the blank feeding pitch.
Like this, improve tube rolling speed, increase feeding pitch, and, finally cause increasing the production capacity of milling train owing to improving the shortening downtime that device reliability and life-span cause.
