Abstract

The invention 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 rolls is installed on the fixed frame. A swing frame is installed on the fixed frame through an articulated shaft, and a pair of swing rolls 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 rolls and the fixed rolls to be output. After the structure is adopted and 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

Correcting device before the stretch bending-straightening machine circle shear

Technical field

The present invention relates to a kind of auxiliary equipment of stretch bending-straightening machine, 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 is a kind of finishing equipment that product is stretched, aligns, cleans, cuts edge; The user is more and more higher to the strip width required precision now, so also just more and more higher to the equipment performance requirement, maximum 7.5mm is measured in sometimes monolateral side cut, and the 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 because of about move about narrowly when wide can occur shearing material the time, namely impartial from incipient both sides, then monolateral broken hem width degree is changeable, sometimes in addition boundless can be broken, directly affect end product quality or cause and scrap.

Although the uncoiler of prior art has the midline detect device, but broken limit device approximately has 42 meters from the uncoiler to the disk, when band is sidelong material out from uncoiling, when retrodeviating from 1 millimeter to entrance pinch roll, when being linear deviation, understand tens millimeters of deviations (wherein not considering the alignment error of each rubber roll and jockey pulley) to circle shear; 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 problem to be solved in the present invention provides a kind of front correcting device of stretch bending-straightening machine circle shear that can thoroughly solve band sideslip problem when shearing.

In order to solve the problems of the technologies described above, correcting device before the stretch bending-straightening machine circle shear of the present invention, comprise frame, be provided with fixed mount on the frame, 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 the fixed mount, by a jointed shaft swing span is installed on the fixed mount, a pair of oscillating roller is installed on the swing span, be equipped with between swing span and the fixed mount and can drive the hydraulic cylinder that swing span swings along jointed shaft, band to be conveyed is exported after walking around successively oscillating roller and stationary roll.

Described two stationary rolls are installed in respectively the up and down two ends of fixed mount, and the central shaft of two stationary rolls is positioned on the same center line.

Described two oscillating rollers are installed in respectively the up and down two ends of swing span, and the central shaft of two oscillating rollers also is positioned on the same center line.

After adopting above-mentioned structure, because what arrange is installed in the stationary roll on the fixed mount and is installed in oscillating roller on the swing span, swing span is swung along jointed shaft by Driven by Hydraulic Cylinder, rectify a deviation thereby after band skew to be conveyed, can swing by the Driven by Hydraulic Cylinder swing span thus, band sideslip problem when having solved shearing fully, 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 the Economy Benefit value.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, be that correcting device is described in further detail before the stretch bending-straightening machine circle shear of the present invention to Fig. 1 of the present invention.

As shown in the figure, correcting device before the stretch bending-straightening machine circle shear of the present invention, comprise frame 9, be provided with fixed mount 3 on the frame 9, 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 the guiding is installed on the fixed mount 3 draws positive stationary roll 4, when guaranteeing the band outlet on the roll line absolute altitude; By a jointed shaft 8 swing span 2 is installed on the fixed mount 3, a pair of oscillating roller 1 is installed on the swing span 2, be equipped with between swing span 2 and the fixed mount 3 and can drive the hydraulic cylinder 5 that swing span 2 swings along jointed shaft 8, two bar effects of hydraulic cylinder push away or draw after swing span is swung, wherein, two stationary rolls 4 are installed in respectively the up and down two ends of fixed mount 3, the central shaft of two stationary rolls 4 is positioned on the same center line, two oscillating rollers 1 are installed in respectively the up and down two ends of swing span 2, the central shaft of two oscillating rollers 1 also is positioned on the same center line, and band 7 to be conveyed is walked around oscillating roller 1 and stationary roll 4 rear outputs successively.

Its operation principle is as follows:

After midline detect device 6 detects the band center line and departs from, can send the action of a voltage signal control hydraulic cylinder; If when finding that band is turned left lateral deviation, then hydraulic cylinder 5 notified rodless cavity actions, swing span lifts to the right, because on-line tension effect, band is with putting to the right behind the oscillating roller 1 on the swing span 2, and center line is mobile to the right, again two stationary roll 4 correctings on fixed mount 3, consistent with the front midline detect when the band center line, hydraulic cylinder stops action; Otherwise, when finding that the band center line is turned right lateral deviation, then hydraulic cylinder 5 notified rod chamber actions, swing span lifts to the left, band is put with the 1 backward left side of oscillating roller on the swing span 2, center line is mobile to the left, and namely center line is mobile to the left, again two stationary roll 4 correctings on fixed mount 3, when the band center line consistent with the front midline detect, hydraulic cylinder stops action, thereby makes the band center line in setting value, and the both sides strip width is impartial when entering circle shear.
