Description

A kind of flying shear being driven with bilateral gear

Technical field

The utility model belongs to rolling machinery field, is related to and flies for the start stop mode roller to continuous production Strip shearing Cut equipment, more particularly to a kind of flying shear being driven with bilateral gear.

Background technology

Domestic hot-rolled and cold-rolled start stop mode drum type flying shear equipment, is confined to the product of external introduction, mainly including day more at present The large-scale metallurgical equipment supply enterprise such as this Mitsubishi, German western mark, VAI.According to the difference of shear plate strip product thickness, The flying shears used on plate ＆ strip production line are broadly divided into hot rolled steel plate bundling with flying shear, cold continuous rolling thin plate bundling flying shear With very thin plate shearing flying shear on cold rolling subsequent treatment line.This three classes drum type flying shear structure type is roughly the same, but device structure Size gap is than larger, and being mainly reflected in cutter shaft centre-to-centre spacing or diameter of cylinder size has significant difference, shears thicker strip, The impulsive force of shearing it is bigger, it is necessary to equipment rigidity it is also bigger, it is necessary to cutter shaft centre-to-centre spacing or diameter of cylinder it is also bigger.From The type of belt drive of cutter shaft is seen, typically configures synchromesh gear engagement to transmit moment of torsion by upper cutter shaft and lower, current upper and lower knife Axle meshed gears form mainly has following two forms：

1. unilateral Helical gear Transmission is simultaneously disappeared gap using major-minor tooth, this flying shear is with relatively more, and major advantage is structure letter Single, gear is easy for installation, it is possible to drive the circumferential movement of another cutter shaft by the axial movement of cutter shaft well, so that real The adjustment of existing blade clearance.

2. the major-minor gear of the first form to be taken apart to the bilateral for being opened in memorial archway respectively, major-minor gear staggers in phase Certain angle eliminates gear backlash.The structure of this form is used for slab shearing, can do the facewidth of major-minor gear Greatly, bigger moment of torsion is transmitted, but very high is required to assembly precision.And due to a side gear when flying shear starts engaged transmission, Another side gear engaged transmission when flying shear is braked, actually cutter shaft is still within cantilever position, under the conditions of the same facewidth The antitorque ability of cutter shaft is not improved.

Above two mode is carried from cutter shaft gear from the point of view of the constraint of load square, cutter shaft all similar " cantilevered " support, knife Axle is when shearing band, and especially for spiral scissors, strip is sheared by pointwise, side pointwise movement of the shearing moment from strip To opposite side, and the gear of this cutting torsion is carried only in side, this certainly will cause the torsional deflection of cutter shaft, so that The gap of upper and lower cutting edge is increased.To improve the torsional rigidity of cutter shaft, common mentality of designing is to increase cutter shaft diameter to ensure knife Axle has enough torsional stiffnesses, and the flying shear diameter that such as hot rolling is used has reached 1000mm, meanwhile, cutter shaft centre-to-centre spacing also adds therewith Greatly, this certainly will cause gear, bearing, the size of framework memorial archway and weight all to significantly improve, the rotary inertia of whole transmission system Also increase, thus it requires the power and moment of torsion of driving motor are also required to lifting, add weight of equipment and manufacturing cost, invest into This also and then increases, and lacks the market competitiveness.

And sheared for thin material, although shearing impact power relative thick material is much smaller, but blade clearance then requires controlled It is smaller；Meanwhile, to blade clearance, its uniformity requirement in the width direction is higher, and blade clearance is too small to occur as soon as upper and lower cutting edge Interfere with each other and forge a knife, and blade clearance is excessive occurs that strip cuts continuous phenomenon, influences the rhythm of production of whole unit, drop Low production efficiency, or even there are useless, substandard products etc..

In summary, flying shear needs to bear moment huge shearing impact in shear history, and produces week according to coil of strip Phase needs frequent starting and braking, has been also subjected to the moment of torsion of positive and negative both direction, therefore, for ensureing upper and lower cutter shaft synchronization Gear pair needs enough intensity and can be in positive and negative both direction while control running clearance, tooth during avoiding rotating forward and invert There is sideshake and send impact sound in wheel engagement.On the other hand, for the shearing of Strip, to ensure that its shearing section occurs without hair Pierce and strip side either occur and cut opposite side cutting continuous phenomenon or thin strip occurs without the phenomenon of " tear ", this is just needed Ensure whole upper and lower cutting edge when shearing, along cutting edge width blade clearance uniformity.Also, with current The production needs and development trend of " being rolled with casting generation " technology, the strip steel specification scope of same unit production are more wide in range, strip rule Lattice scope has expansion to thick, thin both direction, and this requires flying shears to need higher rigidity to tackle when slab is sheared Cutter shaft torsional deflection, while ensureing blade clearance uniformity again to meet the shear precision requirement of thin material.
