Abstract
The utility model relates to a diamond disc with horizontally staggered tool bits, which comprises the tool bits (1), a basal body (2) and teeth protection blocks (3), wherein the tool bits (1) take the shape of nodes and are connected to the basal body (2) at the periphery; the basal body (2) takes the shape of a ring, uniformly distributed U-shaped grooves (2a) are formed at the periphery, and an unthreaded hole (2b) is formed in the center; each teeth protection block (3) is arranged between every two adjacent U-shaped grooves (2a); the tool bits (1) are distributed on the basal body (2) in a horizontally staggered manner and are positioned on the two edges of the U-shaped grooves (2a) on the basal body (2); and the thickness of the tool bits (1) is half of that of the disc. The utility model has the benefits that the diamond disc solves the defects of large cutting resistance force, slow process, excessively generated heat and easily cracked tool bits from the root parts during the operation of the prior disc, and provides the diamond disc with high cutting speed, fast heat radiation and long service life which can be used for saw-cutting on concrete and asphalt pavement.
Description
Technical field
The utility model relates to a kind of diamond disc, and staggered diamond disc can be widely used in the sawing of materials such as concrete, bituminous paving about particularly a kind of cutter head.
Background technology
At present, diamond disc is in field extensive uses such as municipal road and bridge maintenance, building, finishings.In the prior art, diamond disc is when sawing, and two sides and the cut surface of cutter head rub, increased the resistance of saw blade cutting, made the saw blade cutting speed slack-off, and produce a large amount of heats, the saw blade temperature raises rapidly, has a strong impact on the service life of saw blade.In addition, because cutter head root and matrix weld do not contain diamond, cutter head root serious wear, cutter head ruptures from root easily.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and staggered diamond disc about a kind of sharp more durable, rapid heat dissipation, the life-span is long, cost is low cutter head is provided.
The technical solution of the utility model is: staggered diamond disc about a kind of cutter head, comprise cutter head, and matrix protects the tooth piece.It is block that cutter head is joint, links to each other at periphery with matrix; It is circular that matrix is, and periphery is provided with uniform U type groove, and the center is provided with unthreaded hole; Every interval U type groove is provided with one and protects the tooth piece.Cutter head is interspersed about being on the matrix, and cutter head is positioned at the U type groove both sides of matrix, and the thickness of cutter head is 1/2 of saw blade thickness.
The beneficial effects of the utility model are: the cutting resistance is big when having solved the work of existing saw blade, speed is slow, the heat that produces is many, cutter head is easily from deficiencies such as root fractures, provide a kind of cutting speed fast, rapid heat dissipation, staggered diamond disc can be used for the sawing of concrete, bituminous paving about the cutter head of life-span length.

The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
Staggered diamond disc comprises cutter head 1 about cutter head, and matrix 2 protects tooth piece 3.It is block that cutter head 1 is joint, links to each other at periphery with matrix 2; Matrix 2 is circular, and periphery is provided with uniform U type groove 2a, and the center is provided with unthreaded hole 2b; Every interval U type groove 2a is provided with one and protects tooth piece 3.Cutter head 1 is interspersed about being on the matrix 2, and cutter head 1 is positioned at the U type groove 2a both sides of matrix 2, and the thickness of cutter head 1 is 1/2 of saw blade thickness.
Claims (2)
1. staggered diamond disc about a cutter head comprises cutter head (1), and matrix (2) protects tooth piece (3); It is characterized in that: it is block that cutter head (1) is joint, links to each other at periphery with matrix (2); Matrix (2) is circular, and periphery is provided with uniform U type groove (2a), and the center is provided with unthreaded hole (2b); Every interval U type groove (2a) is provided with one and protects tooth piece (3).
2. ask staggered diamond disc about 1 described cutter head according to right, it is characterized in that: described cutter head (1) is interspersed about being on the matrix (2), and cutter head (1) is positioned at U type groove (2a) both sides of matrix (2), and the thickness of cutter head (1) is 1/2 of saw blade thickness.
