Description
Technical field
The present invention relates to a kind of multi-wire saw technology, particularly relate to a kind of multi-wire saw equipment and tension adjustment mechanism thereof.
Background technology
Line cutting technology is the most more advanced evolution process technology, and its principle is the golden steel wire by high-speed motion
Workpiece to be processed (such as: silicon rod, sapphire or other quasiconductor hard brittle materials) is rubbed, the side's of cutting out ingot, thus
Reach to cut purpose.In the cutting process to workpiece, the gold steel wire guiding by guide roller, main line roller is formed a bracing cable
Net, and workpiece to be processed realizes the feeding of workpiece by the rise and fall of workbench, under the effect of compression pump, is assemblied in equipment
On cooling water automatic spraying device cooling water is sprayed to gold steel wire and the cutting position of workpiece, gold steel wire move back and forth and produce
Cutting, to be cut into polylith by hard brittle materials such as quasiconductors the most simultaneously.Line cutting technology and traditional knife saw sheet, grinding wheel and
Inner circle cutting is compared has efficiency height, production capacity height, precision advantages of higher.
Existing multi-wire saw equipment such as crystalline silicon rod cutting machine etc. typically at least includes: frame, is arranged in described frame
For carrying the workbench of crystalline silicon rod, for the reel of wrapping wire, multiple reel and liftable cutting roller etc., right
In the cutting process of crystalline silicon rod, steel wire by the guiding of ten several reel, between multiple cutting rollers on form a pull spring net,
And crystalline silicon rod to be cut is when being fixed on described workbench, cutting roller is lowered, and under the effect of compression pump, dress
Cooling water is sprayed to gold steel wire and the cutting position of crystalline silicon rod by the cooling water automatic spraying device fitted on equipment, by gold steel wire
Move back and forth and workpiece is produced cutting, crystalline silicon rod to be cut into several sections the most simultaneously.
In above-mentioned cutting operation, the effect of gold steel wire holds the balance, even if but best golden steel wire, its ductility and wear-resisting
Degree is also limited, say, that gold steel wire can be tapered, until being finally pulled off in reciprocating motion.Present is multi-thread
Cutting equipment (lathe) all can design gold steel wire tension force compensation mechanism, for making up the ductility during gold steel wire goes and back running.Figure
1 is shown as in the linear cutting equipment of prior art gold steel wire tension force compensation mechanism schematic diagram, as it is shown in figure 1, described gold steel wire is opened
Force compensating mechanism includes: the drag board 11 being arranged in frame 10, the cutting being arranged on drag board 11 wheel 12, guide roller
13, regulating wheel 14, gold steel wire 15 are wound between described cutting wheel 12, guide roller 13 and regulating wheel 14, in described
The air spring 16 for drawing regulating wheel 14 it is additionally provided with and for sensing the tension force of gold steel wire 15 to drive on drag board 11
The displacement transducer 17 of this Pneumatic extension part 16 (such as cylinder or air spring etc.).In cutting process, work as displacement transducer
The when that 17 tension force sensing golden steel wire 15 generation being wound on described regulating wheel 14 changing, can order about described pneumatic
Extensible member 16 pulls described regulating wheel 14 in horizontal motion, and then reaches the effect of regulation to supplement the change of this tension force.
But due to this tension force compensation mechanism uses Pneumatic extension part as absorbing the driving element of tension force, and pneumatic element itself
There is the performance of elastic telescopic, be continually changing due to the tension force of gold steel wire in actual cutting process, such as cutting process
In due to compensate tension force result cause gold steel wire tension force become big time, this Pneumatic extension sword can discharge gold steel wire and cause gold steel wire
Lax, and then it is unfavorable for cutting operation；Furthermore, the cutting wheel of the same side in the cutting equipment of present technology is all arranged at same
On individual cutting roller, and the different degrees of wear is had to often lead to the girth of each cutting wheel on cutting wheel due to gold steel wire in cutting
That does not waits changes, and the result produced is that the steel wire tension being back and forth wound on each cutting wheel is different, and then causes
Displacement transducer between described cutting wheel and guide roller can not be precisely sensed the tension variation of reality, i.e. described gas
The tension force that dynamic Extension sword then can not obtain tension signal accurately and will produce in time absorbs, so being still unfavorable for cutting operation.
