Abstract
The utility model discloses a diamond saw bit capable of fast cutting hard and brittle materials without swinging or edge cracking. The diamond saw bit comprises a base body and a cutter head, wherein the outer edge of the base body is provided with water openings. The utility model has the main design scheme that the inner ends of the water openings are in a circular shape, a plurality of 0.8 mm to 1.2 mm gaps are arranged on the cutter head, and each gap is correspondingly communicated with one water opening. The diamond saw bit with the design has the advantages that the stress concentration can be reduced through the circular design of the inner ends of the water openings of the base body, the cracking of the base body is prevented, and the cutter head is provided with the gaps so that the tensile deformation has a certain release space in the cutting process, so the occurrence of phenomena such as twisting and edge cracking are completely avoided, the gaps are controlled between 0.8 mm and 1.2mm, the chip removal and cooling effects of the cutter head can be enhanced, a mold is convenient to be directly adopted for processing, and the manufacture cost is reduced.
Description
Technical field
The utility model relates to diamond saw blade, specifically a kind of diamond saw blade that carries out the hard crisp material of fly-cutting.
Background technology
General continuous tooth diamond saw blade is used for driedly cutting or wet cutting the material that hardness height, fragility greatly, easily collapse the limit more.As pottery, granite etc.But the rack saw sheet under the effect of cutting resistance and driving force, usually can produce stretcher strain, distortion in the high-speed cutting process continuously, and then causes the saw blade swing, influence cutting speed, even the limit phenomenon is collapsed in generation.
The utility model content
The purpose of this utility model just provides the hard crisp material of a kind of energy fly-cutting, does not swing, do not collapse the diamond saw blade on limit.
The purpose of this utility model is to realize like this
Diamond saw blade provided by the utility model, comprise matrix and cutter head, the outer rim of matrix has the mouth of a river, and the inner that its design main points are the mouth of a river is for circular, cutter head is provided with the slit of several 0.8～1.2mm, the corresponding connection in a mouth of a river of slit and matrix outer rim.
The diamond saw blade of design like this, the circular design of the inner, the matrix mouth of a river can reduce stress to be concentrated, and prevents MATRIX CRACKING; Cutter head has slot can make the stretcher strain in the cutting process that certain Free up Memory is arranged, thereby has avoided distortion fully, collapse the generation of limit phenomenon; Slot is controlled at 0.8～1.2mm, both can increase the effect of cutter head forced-ventilated bits and cooling, is convenient to again directly adopt Mould Machining, thereby has reduced manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model includes matrix 1 and cutter head 2.The outer rim of matrix 1 has the mouth of a river 3, and the inner at the mouth of a river 3 is circular.Cutter head is provided with the slit 4 of several 0.8～1.2mm.Each slit 4 is connected with the mouth of a river 3 of matrix outer rim.In order to strengthen the durability of cutter head, described cutter head can adopt the adamantine alloyed powder sintering of parcel or be welded on the mouth of a river and the matrix between the mouth of a river of matrix outer rim.
Claims (2)
1. but the diamond saw blade of the hard crisp material of fly-cutting, comprise matrix (1) and cutter head (2), the outer rim of matrix (1) has the mouth of a river (3), the inner that it is characterized in that the mouth of a river (3) is for circular, cutter head (2) is provided with the slit (4) of several 0.8～1.2mm, the corresponding connection in a mouth of a river (3) of a slit (4) and matrix outer rim.
2. diamond saw blade according to claim 1 is characterized in that cutter head is with the adamantine alloyed powder sintering of parcel or is welded on the mouth of a river (3) and the matrix (1) between the mouth of a river (3) of matrix outer rim.
