Description
Technical field
The utility model relates to the metallurgical industry equipment technical field, relates in particular to hydraulic pressure cutting edge machine, and particularly aluminium sheet mill hydraulic pressure is cut shearing edge gap adjusting device, is applied to large aluminium-board tandem rolling unit.
Background technology
The large aluminium-board tandem rolling unit of prior art after the roughing unit and before the mm finishing mill unit, is separately installed with the light pruning of a 120～150mm heavy pruning and a 40～60mm.Heavy pruning is used for thicker aluminium sheet is carried out cutting head cutting tail, removes thicker aluminium sheet warpage end to end, is convenient to follow-up rolling.Thicker aluminium sheet is through the roughing mill reversible rolling of some passages, and the thickness attenuation still can produce warpage, arc etc. end to end, at this moment must carry out cutting head cutting tail with light pruning, is convenient to the mm finishing mill unit band of nipping, and is rolling smoothly.Above-mentioned two kinds of hydraulic pressure are cut the blade clearance and are fixed value.The deficiency of prior art is: because the heavy pruning blade clearance is big and can not onlinely adjust, be unfavorable for shearing the sheet material of this kind than minimal thickness, therefore, must promptly be provided with heavy pruning on the unit and be provided with light pruning again, Neither of the two can be dispensed.This set has brought weight of equipment big, the problem that one-time investment is big.
Summary of the invention
The purpose of the utility model provides stepless adjustment blade clearance, a kind of blade clearance device, shears to adapt to different thicknesss of slab, makes a heavy pruning can adapt to the shearing of slab and thin plate, thus cancellation light pruning equipment.
The technical scheme that the utility model technical solution problem is adopted is: large aluminium-board hot-milling-machine hydraulic shearing machien shearing-cutter interval on-line adjusting device; The upper cutter head, cutting edge base and the cutting edge that comprise large aluminium-board hot-rolling mill hydraulic shearing machine; It is characterized in that said large aluminium-board hot-milling-machine hydraulic shearing machien shearing-cutter interval on-line adjusting device also comprise clearance adjustment mechanism and with spring compression mechanism, said clearance adjustment mechanism comprises fixedly wedge in the chute that is installed in tool rest, moves wedge and hydraulic cylinder, said fixedly wedge is that a face is the inclined-plane wedge; Fixedly the wedge inclined-plane outwards is fixed on the upper cutter head; Said hydraulic cylinder body is fixed on the outer end of upper cutter head, and said mobile wedge is that a face is the inclined-plane wedge, and it is identical with the inclined-plane gradient of fixing wedge to move the inclined-plane of wedge; The inclined-plane is relative; Mobile wedge places fixedly between the wedge inclined-plane and cutting edge base, and the outer end of moving wedge is connected with the piston rod of hydraulic cylinder, fixedly in chute, moves back and forth on the wedge inclined-plane in the driving lower edge of hydraulic cylinder; Said spring compression mechanism comprises fairlead, back-moving spring and clamping screw; Said fairlead lower end places on the cutting edge base; Fairlead upper end pass move wedge and fixedly wedge connect; Back-moving spring is installed on the clamping screw in the fairlead, and the clamping screw upper end joins hydraulic cylinder and the translation of back-moving spring drive upper scissor blade with fixing wedge.。
The said large aluminium-board hot-milling-machine hydraulic shearing machien shearing-cutter interval on-line adjusting device of the utility model, the gradient that it is characterized in that said fixedly wedge and mobile wedge is 1: 10-1: 30.
The said large aluminium-board hot-milling-machine hydraulic shearing machien shearing-cutter interval on-line adjusting device of the utility model is characterized in that said hydraulic cylinder is the hydraulic cylinder of band displacement transducer.
The said large aluminium-board hot-milling-machine hydraulic shearing machien shearing-cutter interval on-line adjusting device of the utility model is characterized in that the displacement sensor and the single board computer communication of said hydraulic cylinder.
The principle of the utility model is; Move wedge and fixedly in chute, move back and forth on the wedge inclined-plane, make the cutting edge that is fixed on the tool rest produce lateral displacement in the driving lower edge of hydraulic cylinder.Thereby reach the purpose of regulating the cutting edge sideshake.Give certain pretightning force during the back-moving spring assembling, make cutting edge remain tight the contact with mobile wedge.
The invention has the beneficial effects as follows: the blade clearance adjusting range is increased, adapt to shearing thickness on a large scale; Can reduce by an equipment, reduce weight of equipment, practice thrift cost of investment.With the wide aluminium sheet hot continuous rolling of 2000mm unit is example, and light pruning weight is about 160 tons, cost-saved like this more than 5,000,000.The large aluminium-board milling train, like 4200mm aluminium sheet hot continuous rolling unit, light pruning weight is more than 250 tons, and cost-saved nearly 8,000,000.If add expenses such as hydraulic drive and control system, it will be more considerable practicing thrift investment.
