Description
The utility model relates to a kind of saw cutting device, particularly is applicable to the online single or saw cutting device of metal material in groups of sawing.
Germany DE3242572 patent disclosure a kind of saw blade that has the saw blade cover be the saw cutting device that cantilevered is installed, it is applicable to that the garden saw blade is installed in the saw that is supported on the planker axle head, the installation of the saw blade of this saw cutting device adopts nut screwing clamping on power transmission shaft, and is irrelevant with the saw blade cover.This machine saw blade cover is made up of upper lid and lower cover two parts, and upper lid is attached on the planker rigidly, and lower cover is lining shape and guide post matches, and can slide at the extending part of upper lid, realizes radial displacement.The shortcoming of this saw cutting device is, be contained in axle head the saw blade cantilever, the amount of deflection of stand under load back boom end causes saw blade crooked, make saw blade under the effect of additional axial force, produce bigger axial vibration, increase the sawing noise, cause environmental pollution and the saw kerf width is strengthened, increased metal wastage, coping saw blade causes the replacing saw blade time-consuming on power transmission shaft with nut screwing clamping simultaneously, influences the operating rate of saw.
In order to overcome the above-mentioned shortcoming of existing saw cutting device, the purpose of this utility model provides a kind of applicable to the reducing noise, change the convenient and time-saving saw cutting device of saw blade of various ways saws such as slide-like, link-type, gate-type, has energy-conservation simultaneously and advantage material-saving.
Saw cutting device described in the utility model comprises saw blade, saw blade cover and saw blade supporting.Wherein saw blade is the saw blade assembly of combining structure, and the saw blade cover is axial open-close type structure, and noise reducing plate, saw blade employing double supporting structure are housed in the saw blade cover.The saw that above-mentioned saw cutting device has been installed can reach the purpose of this utility model.
Concrete solution is as follows:
Saw cutting device described in the utility model, saw blade assembly wherein comprise chuck body 16, platen 21, saw blade 34 and combine as a whole by bolt 33, can change saw blade by the mode of changing the saw blade assembly when blade wear or when damaging.The saw blade assembly is enclosed within on the power transmission shaft 7 by chuck body 16 whole skies again, the chuck body socket end has jaw clutch 44 to be meshed with jaw clutch 45 on the half-clutch cover 15 that is fixed in key 35 on the power transmission shaft 7, to transmit moment of torsion, realization is to the transmission of saw blade, the saw blade assembly of this combining form can be realized providing convenience for the fast assembling-disassembling saw blade again to the transmission of saw blade, also improve the rigidity of saw blade simultaneously, helped adopting the attenuate saw blade.
On the inboard relevant position of the chuck body of saw blade assembly and platen, be processed with the cannelure of placing damping ring and ring-type damping sheet respectively, when assembling saw blade assembly, damping ring 22 and ring-type damping sheet 23 are put into groove in advance, also clamp saw blade tightly by means of bolting, the vibration that produces when making sawing is subjected to damping to reduce noise.
The axial open-close type saw blade cover of saw cutting device described in the utility model comprises that adopt cast structure fixing partly covers 17 and move and partly cover 19.Fixing half cover is installed on the loam cake 11 and base 48 of supporting drive shaft by bolt 47; move and partly to cover 19 and fixingly partly cover on 17 and the guide posts of protecting with cover 38 39 link with being installed in by the bearing holder (housing, cover) on it 37; under the effect that is installed on the hydraulic cylinder 41 on fixing half cover, make mobile half cover do axially-movable along guide post 39; and and the whole together displacement of driven axle 31; thereby realize the axial keying of saw blade cover, make whole quickly and easily loading and unloading saw blades groups part become possibility like this.
Be in fixing half cover and move the inboard noise reducing plate 18,20 of half cover and be fixed on fixing half cover by bolt 32 and move in half cover.Form the effect of the low sound intensity of landing by means of the expanded metal lath clamping by porous light-weight materials such as ultra-fine fibre glass or aluminosilicate refractory fibers.
The saw blade double base of saw cutting device described in the utility model is: the aiding support and the tapered shaft end on the chuck body 16 that are had the power transmission shaft that the driven axle 31 of bellmouth constituted by end cap 27, garden nut 28, bearing 25,26, bearing a set of cups 24, separation sleeve 29, bolt 30, end constitute together with the bearing 10,12 that power transmission shaft 7 is supported on loam cake 11, the base 48.Because the bellmouth of driven axle 31 ends in the auxiliary supporting system of power transmission shaft is supporting the tapered shaft end on the chuck body 16, under the effect that is installed on hydraulic cylinder 41 pulling force on fixing half cover, make the power transmission shaft that the saw blade assembly is installed realize keyless transmission to driven axle.Because saw blade adopts double supporting structure, the amount of deflection of power transmission shaft when having reduced saw blade work, and saw blade be difficult for crooked, both reduced saw blade axial amplitude, reduce noise pollution, reduced the saw kerf width again, saved metal material and reduced energy consumption.
Saw cutting device of the present utility model can be used as the saw cutting device of new system saw, also can be used for replacing the saw cutting device of existing saw, so that it is undergone technological transformation.
Adopt characteristics such as double supporting structure because saw cutting device of the present utility model has the axial open-close type saw blade cover, saw blade of the saw blade assembly of combining structure, interior dress noise reducing plate, therefore can reach reduce noise, change saw blade convenient, save time and effect such as saving metal material and energy.The saw of saw cutting device of the present utility model has been installed, and its overall noise reduces by 15 decibels than common saw.Adopt the saw of saw cutting device of the present utility model, change the saw of the time ratio prior art of a saw blade and change saw blade required time minimizing 50%.The reducing of coping saw blade attenuate, saw blade axial amplitude also brought effect energy-conservation, material-saving, it for example is 1800 millimeters saw cutting device for the saw blade diameter, saw blade thickness can be reduced to 8 millimeters by original 12 millimeters, it is attenuate 1/3, then required sawing force reduces 1/3, also the sawing power reduction 1/3 that promptly consumes has reduced energy consumption significantly.With such attenuate saw blade, the saw kerf width can be not less than 13 millimeters and be reduced to and be not more than 8.5 millimeters by original, by 3-4 saw kerf of every rolled piece saw, but about 300 tons of 650 unit material-saving in every year of 430,000 tons of annual outputs.
