Abstract

The utility model discloses a cutting flywheel knife used for glass, which adopts a discoid wheel body; a first wheel face and a second wheel face are oppositely formed on the wheel body; both the first wheel face and the second wheel face form a first oblique ring surface and a second ring surface which are connected mutually and obliquely at a specific angle in the position near the outer ledge, so that a knife ridge part used for cutting is formed at the junction of the first ring surface and the second ring surface; a plurality of incisions are arranged on the knife ridge part at intervals; the incisions extend to be a first groove and a second groove respectively corresponding to the first oblique ring surface and the second oblique ring surface; the widths of the first groove and the second groove near the position of the knife ridge part are smaller than the width of the position of the knife ridge part, so that glass fragments are not easy to be accumulated in the first groove and the second groove and integral shear marks are kept.

Description

Glass is with cutting flywheel knife

Technical field

The utility model is a kind of glass with the cutting flywheel knife, refer in particular to a kind of can be at the cutting flywheel knife of generation cut channel on glass.

Background technology

All can use a cutting flywheel knife in the time of generally will cutting large stretch of glass material, at the cut channel of generation certain depth on glass, then on glass when applying strength, glass promptly can rupture along cut channel, reaches the purpose of cutting.But patent as TaiWan, China patent announcement numbers 308581, it discloses a kind of glass cutting rotary knife, be that design has protuberance 14 and groove 15 alternative features on radial is outwards chamfered formed perimeter ridge, rotate the contact glass material with this and reach the purpose that produces cut channel, but this kind rotary knife is because of being subject to the mode of tradition cutting, groove 15 is a plane, there is glass fragment to embed wherein during cutting easily, and in cutting, produce extruding with glass, make glass when cut channel ruptures, be easy to generate side cut condition of poor such as ripple glaze, shell line and produce.

The utility model content

The purpose of this utility model is to provide a kind of and is difficult for making glass material to produce the bad glass of cutting edge cutting flywheel knife.

For achieving the above object, glass of the present utility model is a discoid wheel body with the cutting flywheel knife, this wheel body is formed with one first opposite wheel face and one second wheel face, this first wheel face and this second wheel face are being sentenced one first oblique anchor ring and the one second oblique anchor ring that special angle constitutes mutual ramp interface respectively near outer ledge, make this first oblique anchor ring and this second oblique anchor ring joint be formed with an incisory cutter spine, this cutter spine equally spaced is provided with plural otch, this otch also extends one first corresponding groove and one second groove respectively at this first oblique anchor ring with this second oblique anchor ring, and this first groove and this second groove respectively near the width of this cutter spine position less than width away from this cutter spine position, make this first groove and this second groove be difficult for piling up glass fragment and complete cut channel being arranged.

Effect of the present utility model is that when cutting, the side cut of glass is neatly level and smooth, is difficult for piling up glass fragment in first groove and this second groove.

Description of drawings

Fig. 1 is the front appearance synoptic diagram of glass of the present utility model with a preferred embodiment of cutting flywheel knife.

Fig. 2 is the side schematic view after this preferred embodiment is used.

Primary clustering nomenclature in the accompanying drawing:

1 wheel body

11 first wheel faces

12 second wheel faces

13 first oblique anchor rings

14 second oblique anchor rings

15 cutter spines

2 otch

21 first grooves

22 second grooves

Embodiment

Relevant the utility model is to reach technique means and the effect thereof that above-mentioned purpose, feature adopt, and exemplifies a preferred embodiment and cooperates the following drawings to elaborate:

Consult Fig. 1 and Fig. 2, glass of the present utility model is a discoid wheel body 1 with a preferred embodiment of cutting flywheel knife, this wheel body 1 is formed with one first opposite wheel face 11 and one second wheel face 12, this first wheel face 11 is being sentenced one first oblique anchor ring 13 and the one second oblique anchor ring 14 that special angle constitutes mutual ramp interface respectively with this second wheel face 12 near outer ledge, make this first oblique anchor ring 13 and these second oblique anchor ring, 14 joints be formed with an incisory cutter spine 15.

This cutter spine 15 equally spaced is provided with plural otch 2, this otch 2 also extends one first corresponding groove 21 and one second groove 22 respectively at this first oblique anchor ring 13 with this second oblique anchor ring 14, see by first figure, otch 2 slightly is spill under the arcuation, and this first groove 21 and this second groove 22 respectively near the width of these cutter spine 15 positions less than width away from these cutter spine 15 positions, constitute a splayed blade in appearance, can utilize the mode of laser sculpture to reach this structure.

So, make cutter spine 15 have inside and outside two place's knifes edge, the peripheral notch 2 fracture function of partly mainly on glass material, ruling, in enclose the both sides blade that first groove 21 or second groove 22 constituted and then use as glass material is broken, because of this first groove 21 and this second groove 22 are splayed and are not a plane, therefore be difficult for the accumulation glass fragment and quite complete cut channel is arranged, and then make the glass material surface of fracture quite complete and beautiful.

The above only is embodiment of the present utility model, and all simple and easy modification and equivalences of doing according to spirit of the present utility model change design, should be covered by in the claim scope of application.

Claims

1, a kind of glass is with cutting flywheel knife, it is a discoid wheel body, this wheel body is formed with one first opposite wheel face and one second wheel face, this first wheel face and this second wheel face are being sentenced one first oblique anchor ring and the one second oblique anchor ring that special angle constitutes mutual ramp interface respectively near outer ledge, make this first oblique anchor ring and this second oblique anchor ring joint be formed with an incisory cutter spine, it is characterized in that:

This cutter spine equally spaced is provided with plural otch, this otch also extends one first corresponding groove and one second groove respectively at this first oblique anchor ring with this second oblique anchor ring, and this first groove and this second groove respectively near the width of this cutter spine position less than width away from this cutter spine position.
