Description

Cast-cutting saw slice

Technical field

The utility model belongs to cutting technique field, more particularly to a kind of cast-cutting saw slice.

Background technology

Cast-cutting saw slice is a kind of cutting tool, it is widely used in the cutting processing of the hard brittle materials such as stone material, ceramics.Cutting Saw blade is mainly made of matrix and cutter head two parts, and matrix is the main support part of cohesive cutter head, and cutter head is then to use The part of Cheng Zhongqi cuttings, cutter head can consume in use and constantly, and matrix then will not, and why cutter head can rise and cut The effect cut is that diamond is added as material most hard at present, its friction cuttings in cutter head because wherein containing diamond The object of work.

At this stage, with the increasingly increase of industrial production activities, the dosage of cast-cutting saw slice is increasing, but existing cuts Sawing piece still has that matrix is not high with cutter head bonding strength, and cutter head sharpness is poor, and chip removal is not easy in cutting process The deficiencies of.

Utility model content

For above description, the purpose of this utility model is to provide a kind of cast-cutting saw slice, to which existing skill can be overcome It is more insufficient in art.

The technical solution of the utility model is achieved in the following ways：

A kind of cast-cutting saw slice, it includes the matrix with center mounting hole, and is fixed on described matrix periphery at Cutter head, cutter head described in ring it is circumferential formed with multiple cutting grooves along the cutter head radial arrangement, the cutting groove is to the knife The inner side of head extends and is opened in described matrix；The edge of cutter head described in ring is also formed with multiple tooth top grooves for U-shaped, and The tooth top groove present position formed with along the cutter head radially and extend the chip space in described matrix；In described matrix Edge, in the shield tooth that the both sides of the chip space are also formed with extending to the cutter head side, and in the two adjacent cuttings In each shield tooth between groove, the dovetail groove for being configured to connect with the chip space is also enclosed in adjacent shield between cog.

It is adjacent in each chip space between the two adjacent cutting grooves as the restriction to aforesaid way Extension depth of two chip spaces into described matrix is different.

As the restriction to aforesaid way, in the shield tooth positioned at the cutting groove both sides, in the close of the shield tooth In the cutting groove side vertex formed with recess.

As the restriction to aforesaid way, the cutting groove takes the shape of the letter U.

The utility model has the advantage of：

The setting for multiple shield teeth that the cast-cutting saw slice of the utility model passes through matrix edge, can structure improve matrix and cutter head it Between bonding strength, by setting cutting groove, and at the edge of cutter head, tooth top groove is set, by increasing capacitance it is possible to increase the sharpness of cutter head, And by setting chip space, and make it that chip space is extended in matrix, thus can also increase saw blade in cutting chip removal it is logical Smooth property, in addition, by the setting of adjacent shield between cog dovetail groove, can also be beneficial to be molded during saw blade compacting, thus may be such that the cutting Saw blade can overcome the shortcomings of existing saw blade, and have good practicality.

Embodiment

, it is necessary to explanation, the orientation of the instruction such as term " on ", " under ", " interior ", " back of the body " in the description of the utility model Or position relationship is based on orientation shown in the drawings or position relationship, is for only for ease of description the utility model and simplification is retouched State, rather than instruction or imply signified device or element there must be specific orientation, with specific azimuth configuration and operation, Therefore it is not intended that limitation to the utility model.In addition, term " first ", " second " are only used for description purpose, and cannot It is interpreted as indicating or implying relative importance.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The present embodiment is related to a kind of cast-cutting saw slice, and as shown in Fig. 1 combinations Fig. 2, it includes the matrix with center mounting hole 3 1, and cutter head 2 of 1 periphery of matrix at is fixed on, the circumferential direction of cutting ring first 2 is formed with multiple cuttings along 2 radial arrangement of cutter head Groove 4, and cutting groove 4 extends to the inner side of cutter head 2 and is opened in matrix 1, so that cutting groove 4 is communicated with matrix 1.Cutting ring head 2 edge is also formed with multiple tooth top grooves 5 for U-shaped, and is also formed with 5 location of tooth top groove along cutter head 2 The chip space 8 in matrix 1 radially is extended, and in each chip space 8 between two adjacent cutting grooves 4, adjacent two Extension depth of a chip space 8 into matrix 1 is also different.

In the present embodiment, at the edge of matrix 1, in the shield that the both sides of chip space 8 are also formed with extending to 2 side of cutter head Tooth, and among each shield tooth between two adjacent cutting grooves 4, also enclosed between two adjacent shield teeth be configured to The dovetail groove 10 that chip space 8 connects, by the design of the dovetail groove 10, can be easy to shaping of the saw blade in compacting.Meanwhile this It is also classified into embodiment based on adjacent chip space 8 in the difference of the extension depth in matrix 1, the shield tooth for being formed at 1 edge of matrix The small shield tooth 7 arranged close to cutting groove 4, and the larger big shield tooth 6 between the small shield tooth 7 in both sides, and at the same time, prolong The dovetail groove 10 stretched corresponding to the larger chip space 8 of depth is also larger.

, can be beneficial to the chip removal in cutting process by making chip space 8 extend in matrix 1, and chip space 8 extends depth Difference, on the one hand can ensure chip removal effect, on the other hand can also ensure to protect increasing of the tooth to bonding strength between matrix 1 and cutter head 2 Pretend use.

It is further in the present embodiment, in the small shield tooth 7 positioned at 4 both sides of cutting groove, in the small shield tooth 7 close to cutting The vertex for cutting 4 side of groove is also formed with recess 9, and the setting of the recess 9 can also ensure shaping when saw blade is suppressed.In addition, To lift the sharpness of cutter head 2, each cutting groove 4 also takes the shape of the letter U setting in the present embodiment.

The cast-cutting saw slice of the present embodiment, is sintered together after matrix 1 and cutter head 2 are compressing, when specifically used, in Saw blade is installed in angle grinder by heart mounting hole 3 can carry out cutting operation.

The foregoing is merely the preferred embodiment of the utility model, but the scope of protection of the utility model is not limited to This, any those skilled in the art are in the technical scope that the utility model discloses, technology according to the present utility model Design is subject to equivalent substitution or changes the technical solution of gained, should all be covered by the scope of protection of the utility model.
