Abstract

The utility model discloses a single-sided step saw bit base member puts at the central point of base member and has seted up central mounting hole, evenly is provided with the basin along the circumference equidistance in the base member outer fringe, the base member is equipped with the step, and the step divide into inner circle and outer lane with the saw bit base member. Only one side of the base body is provided with a step, and the other side of the base body is integrally a plane. The thickness of the inner ring part is larger than that of the outer ring part. The cutting section of its design has reduced the friction for a short time, reduces lamellar body friction heat, has improved the sharpness of saw bit, has just also promoted the life of cutting efficiency and saw bit base member, can not bring great impact force when cutting slim panel and shake bad panel, and the rigidity that its design portion influences the saw bit base member has guaranteed the cutting quality of saw bit simultaneously.

Description

A kind of single side step saw bit matrix

Technical field

The utility model and a kind of technical field of diamond saw blade, more particularly to a kind of single side step saw bit matrix.

Background technique

Diamond saw blade has a wide range of applications in terms of the materials such as cutting stone material, timber, ceramics, metal, cuts in saw blade During cutting, saw blade surface and cutting material severe friction not only influence cutting efficiency, but also the generation amount of heat that rubs makes to cut Cutter head and saw bit matrix are rapidly heated, and then influence the mechanical property of saw bit matrix itself, reduce its service life.Especially exist In the slim plate cutting of some top grades, common saw blade cutting leads to the problem of not only saw blade severe friction, while because of its saw Piece thickness it is thicker cutting it is not sharp, brought when entering knife biggish impact dynamics can shatter cut thin plate the problems such as, simply The thickness of reduction saw blade be that can solve problem above, but the thinned of saw blade thickness can bring the insufficient of its rigidity that can draw again Cutting beat and twisted straps cut the problem of quality reduces.

Utility model content

The purpose of this utility model is to provide a kind of single side step saw bit matrixes, and the cutting section of design is small to be reduced Friction reduces sheet body frictional heat, improves the sharpness of saw blade, also just improve the use of cutting efficiency and saw bit matrix Service life will not bring biggish impact force shake bad plate when cutting slim plate, while its design portion influences the rigid of saw bit matrix Property ensure that the cutting quality of saw blade.

In order to realize above-mentioned technical characteristic, purpose of the utility model is realized as follows: a kind of single side step saw blade Matrix, offers center mounting hole in the center of matrix, is circumferentially equidistantly evenly arranged with sink in matrix outer rim, described Matrix is equipped with step, and saw bit matrix is divided into inner ring and outer ring by step.

Described matrix only has one side and is equipped with step, and in addition one side is whole is a flat surface.

The inner round portion thickness is greater than outer perimeter section thickness.

The utility model has the advantages that:

The utility model is divided into inner ring and outer ring, outer ring because of step by providing a kind of single side step saw bit matrix, matrix Part is designed relatively thin, and the cutter head of welding is also just thinner than common saw blade tip, and outer ring position and material when cutting are cut The small friction reduced between saw blade and material of section reduces piece body heat content, and then promotes the use of cutting efficiency and saw blade Service life, cutter head be thinned also brings cutting sharpness promotion, would not also be generated when entering knife it is huge impact and it is shatter Thin plate；Inner round portion design is thicker, increases the rigid of saw blade, improves cutting quality；Its step design is single simultaneously Face reduces its difficulty in blades machining step.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the A-A cross-sectional view of Fig. 1.

In Fig. 1,1-matrix, 2-steps, 3-sinks, 4-center mounting holes；

In Fig. 2,2-steps, 5-inner rings, 6-outer rings.

Specific embodiment

The embodiments of the present invention is described further with reference to the accompanying drawing.

As shown in Figs. 1-2, a kind of single side step saw bit matrix, offers center mounting hole 4, outside circumferentially on matrix 1 It is equidistantly uniformly arranged sink 3, described matrix 1 is equipped with step 2, and step 2 divides saw bit matrix 1 for inner ring 5 and outer ring 6；It is using In the process, matrix 1 is mounted on cutting main shaft by center mounting hole 4, is protected by being provided with sink 3 in the outer rim of matrix 1 It has demonstrate,proved and has been able to carry out cooling in cutting process, step 2 is provided on matrix and is classified as inner ring 5 and outer ring 6, outer ring 6 Set up separately and haggle over thin, the cutter head of welding is also just thinner than common saw blade tip, and 6 position of outer ring and material when cutting are cut The small friction reduced between saw blade and material of section reduces piece body heat content, and then promotes the use of cutting efficiency and saw blade Service life, cutter head be thinned also brings cutting sharpness promotion, would not also be generated when entering knife it is huge impact and it is shatter Thin plate；The design of 5 part of inner ring is thicker, increases the rigid of saw blade, improves cutting quality.

Further, described matrix 1 only has one side equipped with step 2, and in addition one side is whole is a flat surface；Its step is set simultaneously It is calculated as single side, when blades machining step reduces its difficulty.

Further, 5 segment thickness of inner ring is greater than 6 segment thickness of outer ring.Cutting process is improved by outer ring 6 In blade sharpness, reduce the friction between saw blade and material；And it ensure that its structure is strong by the inner ring 5 Degree.

Above-described embodiment is used to illustrate the utility model, rather than limits the utility model, practical at this In novel spirit and scope of protection of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within With novel protection scope.
