Background

At present, most of the cutting wheels are used for cutting the base material, the cutting wheels are used as the cutting process which is the most widely applied and cost-optimized cutting process, the technology is mature and stable, the process is simple, the efficiency is high, the yield of the base material cutting is mainly dependent on the quality (stability, sharpness of cutting edges, accuracy of processing, suitability of the cutting wheels and a cutting machine and other high-precision characteristics) of the cutting wheels, and therefore, higher requirements are also put forward on cutting.

When the existing cutter wheel is used for cutting processed materials, dust and scraps are generated, a large amount of dust and scraps adhere between tooth gaps of the cutting edges of the cutter wheel, and the phenomenon of scraps clamping occurs, so that the cutting quality is reduced.

Disclosure of Invention

In view of the related problems mentioned in the background art, an object of the present utility model is to provide a cutting blade wheel that prevents chip sticking.

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a prevent cutting cutter wheel of card bits, includes the cutter wheel body, the cutter wheel body includes two quotations that are parallel to each other, the shaft hole of two quotations of intercommunication is seted up along its axial in cutter wheel body center, two the outer circumference of quotation outwards extends and forms symmetrical conical surface, two cutting edge has been seted up to crossing department, two stagger on the conical surface be equipped with the chip groove with cutting edge intercommunication, the chip groove extends to the edge of quotation.

As a further description of the above technical solution: the cutting edge is a V-shaped edge.

As a further description of the above technical solution: the depth of the chip groove from the cutting edge to the disk surface becomes shallow gradually, and the groove width becomes large gradually.

As a further description of the above technical solution: the disc surface is of a concave cambered surface structure.

As a further description of the above technical solution: and an internal spline is arranged in the shaft hole.

As a further description of the above technical solution: the cutter wheel body is made of polycrystalline diamond subjected to cobalt removal treatment.

Compared with the prior art, the utility model has the advantages that:

(1) according to the scheme, the chip grooves which are distributed in a staggered manner are formed in the conical surface of the cutter wheel body, the chip grooves are communicated with the cutting edge, chip guiding and chip discharging functions are achieved, the cutter wheel is blocked by glass chips generated in the cutting process, the contact area and resistance during cutting are further reduced, and the cutting efficiency is improved.

(2) The cambered surface structure of this scheme quotation for indent can reduce the thickness in shaft hole, and the area of contact of shaft hole and connecting axle is little promptly, makes glass bits be difficult for getting into, is difficult for appearing the risk of smooth sword and card bits.

fig. 2 is a schematic structural view of the utility model with a concave cambered surface.

The reference numerals in the figures illustrate:

1. a cutter wheel body; 2. a disk surface; 3. a shaft hole; 4. a conical surface; 5. cutting edges; 6. a chip removal groove; 7. an internal spline.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model;

referring to fig. 1, a cutting knife wheel capable of preventing scraps from being clamped comprises a knife wheel body 1, wherein the knife wheel body 1 comprises two mutually parallel disc surfaces 2, a shaft hole 3 for communicating the two disc surfaces 2 is formed in the center of the knife wheel body 1 along the axial direction of the knife wheel body, symmetrical conical surfaces 4 are formed by outwards extending the outer circumferences of the two disc surfaces 2, cutting edges 5 are formed at the intersection of the two disc surfaces 4, scraps grooves 6 communicated with the cutting edges 5 are formed in the two conical surfaces 4 in a staggered mode, and the scraps grooves 6 extend to the edge of the disc surfaces 2.

The cutting edge 5 is a V-shaped edge, the depth of the chip groove 6 from the cutting edge 5 to the disc surface 2 becomes shallow gradually, the groove width becomes larger gradually, and scraps are discharged along the chip groove 6 during cutting, so that the phenomenon of cutting edge blockage is not easy to occur; an internal spline 7 is arranged in the shaft hole 3, so that the glass cutter wheel and the matched connecting shaft do not rotate relatively.

Referring to fig. 1, the disc surface 2 is of a concave cambered surface structure, so that the thickness of the shaft hole 3 can be reduced, namely, the contact area between the shaft hole 3 and the connecting shaft is small, glass scraps are not easy to enter, and the risks of sliding cutters and scraps are not easy to occur; in addition, the weight of the cutter wheel body 1 is reduced, and inertia is reduced.

In addition, the material of the cutter wheel body 1 is polycrystalline diamond subjected to cobalt removal treatment, and the cutter wheel body 1 material polycrystalline diamond is subjected to cobalt removal treatment, so that the wear resistance and heat resistance of the cutter wheel after treatment are improved to a greater extent, and the service life of the cutter wheel is further prolonged.

To sum up: according to the scheme, chip grooves 6 which are distributed in a staggered manner are formed in the conical surface of the cutter wheel body 1, the chip grooves 6 are communicated with the cutting edge 5, chip guiding and chip discharging functions are achieved, when the cutter wheel body 1 works, the cutter wheel body 1 rotates at a high speed, in the cutting process, the chip grooves 6 arranged on cutting can timely and effectively discharge waste chips generated in the working process, so that the phenomenon that the cutter wheel is blocked by glass chips generated in the cutting process is effectively reduced, meanwhile, the contact area and resistance during cutting are further reduced through the additionally arranged chip grooves 6, and the cutting efficiency is improved;

in addition, the quotation 2 is concave cambered surface structure, can reduce the thickness in shaft hole 3, and the area of contact in shaft hole 3 and connecting axle is little promptly, and when cutter wheel body 1 cutting rotation work, the sweeps are difficult for converging to the direction in shaft hole 3, are difficult for getting into shaft hole 3, are difficult for appearing the risk of smooth sword and card bits.

The above description is only of the preferred embodiments of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
