Abstract
The utility model discloses a correcting device before a disc shear of a stretch-bending straightening machine. The correcting device comprises a rack, wherein a fixed frame is arranged on the rack. A centering detection device which can detect the deviation position of strips to be conveyed is arranged behind the fixed frame, and a pair of fixed rollers is installed on the fixed frame. A swing frame is installed on the fixed frame through an articulated shaft, and a pair of swing rollers is installed on the swing frame. A hydraulic cylinder which can drive the swing frame to swing along the articulated shaft is installed between the swing frame and the fixed frame, and the strips to be conveyed sequentially bypass the swing rollers and the fixed rollers to be output. Through the adoption of such a strucutre, after the strips to be conveyed are deviated, the hydraulic cylinder can drive the swing frame to swing so as to correct deviation, and the deviation problem of the strips during shearing is completely solved. Meanwhile, the machine column speed is not influenced, and any surface scratching and sliding cannot be generated. The product quality is ensured, the intended production target is achieved, the rate of finished products is increased, and the economic benefit is increased.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of stretch bending-straightening machine, and specifically correcting device before a kind of stretch bending-straightening machine circle shear, belongs to cold rolling technical field of processing equipment.
Background technology
Stretch bending-straightening machine be a kind of to product stretch, align, the finishing equipment of cleaning, trimming; Now user is more and more higher to strip width required precision, thus equipment performance is required also just more and more higher, the maximum 7.5mm of monolateral trimming amount sometimes, strip side portion staggered floor is in 0.5mm; The design of some stretch bending-straightening machines is in order to make strip side portion smooth bright and clean, just considers that the broken limit of disk device is placed on to batch side, cut rear directly upper coiling machine.
When actual production is sheared, along with shear time is passed, band moves about and there will be when wide while shearing material narrowly because of left and right, and impartial from incipient both sides, then monolateral broken hem width degree is changeable, sometimes even boundless can be broken, directly affect end product quality or cause and scrap.
Although the uncoiler of prior art has midline detect device, but broken limit device approximately has 42 meters from uncoiler to disk, when band is sidelong material out from uncoiling, while retrodeviating from 1 millimeter to entrance pinch roll, when being linear deviation, to circle shear, understand tens millimeters of deviations (wherein not considering the alignment error of each rubber roll and jockey pulley); And entrance pinch roll to the broken limit of disk without any correction means for correcting, the band forward tension force of walking is controlled, during shearing band not sideslip be impossible.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of front correcting device of stretch bending-straightening machine circle shear that can thoroughly solve band sideslip problem while shearing.
In order to solve the problems of the technologies described above, correcting device before stretch bending-straightening machine circle shear of the present utility model, comprise frame, in frame, be provided with fixed mount, the rear of fixed mount is provided with the midline detect device that can detect band deviation post to be conveyed, a pair of stationary roll is installed on fixed mount, on fixed mount, by a jointed shaft, a swing span is installed, a pair of oscillating roller is installed on swing span, the hydraulic cylinder that can drive swing span to swing along jointed shaft is installed between swing span and fixed mount, and band to be conveyed is exported after walking around successively oscillating roller and stationary roll.
Described two stationary rolls are arranged on respectively the two ends up and down of fixed mount, and the central shaft of two stationary rolls is positioned on same center line.
Described two oscillating rollers are arranged on respectively the two ends up and down of swing span, and the central shaft of two oscillating rollers is also positioned on same center line.
Adopt after above-mentioned structure, due to what arrange, be arranged on the stationary roll on fixed mount and be arranged on the oscillating roller on swing span, swing span is swung along jointed shaft by Driven by Hydraulic Cylinder, thereby after band skew to be conveyed, can swing and rectify a deviation by Driven by Hydraulic Cylinder swing span thus, band sideslip problem while having solved shearing completely, it neither affects machine row speed simultaneously, can not produce again any surface and wipe sliding injury, guaranteed product quality, reached predetermined productive target, improve yield rate, increased Economy Benefit value.

Fig. 3 is the left TV structure schematic diagram of correcting device before the utility model stretch bending-straightening machine circle shear.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, to Fig. 1 of the present utility model, be that correcting device is described in further detail before stretch bending-straightening machine circle shear of the present utility model.
As shown in the figure, correcting device before stretch bending-straightening machine circle shear of the present utility model, comprise frame 9, in frame 9, be provided with fixed mount 3, the rear of fixed mount 3 is provided with the midline detect device 6 that can detect band 7 deviation posts to be conveyed, a pair of can guiding is installed on fixed mount 3 and draws positive stationary roll 4, while guaranteeing band outlet on roll line absolute altitude, on fixed mount 3, by a jointed shaft 8, a swing span 2 is installed, a pair of oscillating roller 1 is installed on swing span 2, the hydraulic cylinder 5 that can drive swing span 2 to swing along jointed shaft 8 is installed between swing span 2 and fixed mount 3, two bar effects of hydraulic cylinder push away or draw after can make swing span swing, wherein, two stationary rolls 4 are arranged on respectively the two ends up and down of fixed mount 3, the central shaft of two stationary rolls 4 is positioned on same center line, two oscillating rollers 1 are arranged on respectively the two ends up and down of swing span 2, the central shaft of two oscillating rollers 1 is also positioned on same center line, band 7 to be conveyed is walked around oscillating roller 1 and the rear output of stationary roll 4 successively.
Its operation principle is as follows:
After midline detect device 6 detects band center line and departs from, can send a voltage signal and control hydraulic cylinder action; When if find, band is turned left lateral deviation, the notified rodless cavity action of hydraulic cylinder 5, swing span lifts to the right, due to on-line tension effect, band is with putting to the right after oscillating roller 1 on swing span 2, and center line moves to the right, then two stationary roll 4 correctings on fixed mount 3, when band center line is with midline detect is consistent above, hydraulic cylinder stops action; Otherwise, while finding that band center line is turned right lateral deviation, the notified rod chamber action of hydraulic cylinder 5, swing span lifts to the left, band is put with the backward left side of oscillating roller 1 on swing span 2, center line moves to the left, and center line moves to the left, then two stationary roll 4 correctings on fixed mount 3, when band center line is with midline detect is consistent above, hydraulic cylinder stops action, thereby makes band center line in setting value, and while entering circle shear, both sides strip width is impartial.
