The invention has the beneficial effects as follows:
Weight of the present invention is less than existing product quality, and can reach within 136 grams, in use, centrifugal force is minimum, and stability is better, substantially prolongs service life.Line wheel body hardness is high, not fragile, and can reclaim reprocessing, reduces cost and drops into, and reduces discarded object to the pollution of environment.And balance test effectively can control the amount of unbalance of product, product is operated stable, centrifugal force is minimum, thus has less frictional force under can ensureing high rotating speed.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in embodiment of the present invention technology, be briefly described to the accompanying drawing used required in the description of embodiment technology below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is line of the present invention wheel body construction schematic diagram;
Fig. 2 is global sections structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
With reference to shown in Fig. 1 and Fig. 2, a kind of polysilicon cutting wire guide roller, comprises line wheel body 1, and line wheel body is made up of carbon fiber, and the excircle of line wheel body is fixedly installed wire grooved ring 2, and described wire grooved ring material is polyurethane.
Wire grooved ring inwall is set to fixed groove 3, and fixed groove is fastened on line wheel body perimeter, and link together for taking turns body with line, degree of being connected firmly is high, is also convenient to integrated injection molding.
Line wheel body surface is positioned at circumferential section and is provided with some through holes 4, also connected by joint pin 5 between fixed groove inwall, joint pin is arranged in through hole, the material of joint pin is identical with the material of wire grooved ring and one-body moldedly make, wire grooved ring is close to line wheel body and is fixed, thus the use of glue can be saved, degree of being connected firmly is strong.
Line wheel body is evenly provided with some lightening holes 6, for reducing weight to greatest extent, and is positioned on the surface of fixed groove and bottom surface and is evenly provided with some protruding 7, wire grooved ring can be blocked, increase its firmness.
A preparation technology for polysilicon cutting wire guide roller, comprises the following steps:
Step 1) shape cuts, first divided by carbon cloth and be cut into strip, then strikes out some circular cloth;
Step 2) compression molding, by stacked for multiple circular cloth and put into vulcanizing press mold pressing, make semimanufactured body;
Step 3) essence cuts, and semimanufactured body put into precision machine tool fine finishining, by the removal such as burr, spine, obtains line wheel body;
Step 4) metallic channel ring forming, by coextrusion wire grooved ring on injection machine direct-on-line wheel body peripheral, obtain guide roller;
