Further, described wire grooved ring be connected that post is one-body molded to be made.
Further, described line wheel body is evenly arranged with some lightening holes, and is positioned at fixed groove It is evenly arranged with some projections on interior surface and bottom surface.
The preparation technology of a kind of polysilicon cutting wire guide roller, comprises the following steps:
Step 1) shape cuts, first divided by carbon cloth and be cut into strip, is then punched into some circular cloth;
Step 2) compression molding, multiple circular cloth stackings putting in vulcanizing press are molded, makes half Finished bulk;
Step 3) essence cuts, and semimanufactured body is put into polish in precision machine tool, obtains line wheel body;
Step 4) metallic channel ring forming, by preparing metallic channel on injection machine direct-on-line wheel body peripheral Ring, obtains guide roller;
Step 5) balance test, guide roller carried out dynamic balancing measurement and adjusts, obtaining finished product.
Further, described step 3 center line wheel body surface is positioned at circumferential section and is drilled with by boring machine Some through holes.
Further, the finished product in described step 5 carries out abrasion survey after dynamic balancing measurement adjustment terminate Examination.
The invention has the beneficial effects as follows:
The weight of the present invention is less than existing product quality, it is possible within reaching 136 grams, in use, from Mental and physical efforts are minimum, and stability more preferably, substantially prolongs service life.Line wheel body hardness is high, is hardly damaged, And reprocessing can be reclaimed, reduce cost and put into, reduce the garbage pollution to environment.And balancing side Examination can effectively control the amount of unbalance of product, makes product operating stable, and centrifugal force is minimum such that it is able to Ensure to have under high rotating speed less frictional force.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the skill of the present invention Art means, and can being practiced according to the content of description, below with presently preferred embodiments of the present invention and join After closing accompanying drawing detailed description such as.The detailed description of the invention of the present invention is given in detail by following example and accompanying drawing thereof Go out.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in embodiment of the present invention technology, below will be to embodiment skill In art description, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below It is only some embodiments of the present invention, for those of ordinary skill in the art, is not paying creation Property work on the premise of, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the line wheel body construction schematic diagram of the present invention;
Fig. 2 is the 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, the technical scheme in the embodiment of the present invention is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one
With reference to shown in Fig. 1 Yu Fig. 2, a kind of polysilicon cutting wire guide roller, including line wheel body 1, line Wheel body is made up of carbon fiber, and the excircle of line wheel body is fixedly installed wire grooved ring 2, described wire Grooved ring material is polyurethane.
Being set to fixed groove 3 on wire grooved ring inwall, fixed groove is fastened on line wheel body perimeter, is used for Linking together with line wheel body, degree of being connected firmly is high, also allows for integrated injection molding.
Line wheel body surface is positioned at circumferential section and is provided with some through holes 4, between fixed groove inwall also by Connecting post 5 to connect, connect post and be arranged in through hole, the material connecting post is identical with the material of wire grooved ring And one-body molded making, wire grooved ring is close to line wheel body and fixes, such that it is able to save making of glue With, degree of being connected firmly is strong.
It is evenly arranged with some lightening holes 6, for reducing weight, and position to greatest extent on line wheel body It is evenly arranged with some protruding 7 on surface in fixed groove and bottom surface, it is possible to block wire grooved ring, increases Add its firmness.
The preparation technology of a kind of polysilicon cutting wire guide roller, comprises the following steps:
Step 1) shape cuts, first divided by carbon cloth and be cut into strip, is then punched into some circular cloth;
Step 2) compression molding, multiple circular cloth stackings putting in vulcanizing press are molded, makes half Finished bulk;
Step 3) essence cuts, semimanufactured body put into polish in precision machine tool, burr, spine etc. is gone Remove, obtain line wheel body;
Step 4) metallic channel ring forming, by preparing metallic channel on injection machine direct-on-line wheel body peripheral Ring, obtains guide roller;
Step 5) balance test, guide roller carried out dynamic balancing measurement and adjusts, obtaining finished product, do so The amount of unbalance making guide roller minimizes, and rotation centrifugal force in use the most just decreases, Stability of rotation, does not haves problems such as beating.When therewith whole polysilicon being cut, putting down of its facet Whole degree also brings up to uniform height level, and (rotation is rocked or is beated and the irregularity degree of facet can be caused big Big raising, and grinder can only grind the product in specific thickness, exceedes grinding thickness and can only be considered as waste product), Providing the most excellent product for follow-up grinding, yields is high, brings bigger economic effect for enterprise Benefit.
Wherein, step 3 center line wheel body surface is positioned at circumferential section and is drilled with some through holes by boring machine, After being molded, it is possible to realize firmly connecting, do not fall out, eliminate the step of following process adhesion, also Eliminate the use of adhesive, reduce the pollution to environment.
And the finished product in step 5 carries out wear test after dynamic balancing measurement adjustment terminate, it is ensured that wire The abrasion resistance of grooved ring, thus improve the serviceability of integral product.
Guide roller described in the present embodiment is not owing to having the use of adhesive, when recycling, it is not necessary to Line wheel body is carried out grinding process, and surface will not glue to stick the impurity being difficult to remove, and improves reuse Be worth, and can rapid processing finished product, increase economic efficiency.
Embodiment two
Embodiment two is that with the difference of embodiment one fixed groove takes turns the bonding setting of body with line, such The operation that can save boring in the preparation is set, uses adhesive after direct coextrusion mold, reduce equipment Buying cost.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses The present invention.Multiple amendment to these embodiments will be aobvious and easy for those skilled in the art See, generic principles defined herein can without departing from the spirit or scope of the present invention, Realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, And it is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
