Abstract

The utility model discloses a sawtooth structure of carbide saw blade relates to cutting means technical field, outer knife tip including top surface, relative two sides and inner face and formation, two sides are equipped with a plurality of slots, the slot contact the inner face, and form a pair of cutting knife tip on the inner face. The many of sawtooth side formation improve effect of cutting to the cutting knife point, and the wearing and tearing circumstances of outer knife tip when effectively reducing the use increases hard alloy saw web life, and chip removal and radiating technological effect can be played to the side slot while.

Description

A kind of broached-tooth design of sintered carbide circular saw

Technical field

This utility model is related to cutting tool technical field, especially a kind of broached-tooth design of sintered carbide circular saw.

Background technology

The broached-tooth design of existing sintered carbide circular saw, as shown in figure 1, using the top surface of sawtooth, side and inner face institute The point of a knife of formation is being cut, but above-mentioned broached-tooth design only one of which point of a knife, and effective cut point is single, and cutting effect is paid no attention to Think, while the service life of sawtooth can only extend by lifting its hardness.

Utility model content

For the problems referred to above, this utility model provides a kind of broached-tooth design of sintered carbide circular saw, both sides band cutting ditch Groove.

A kind of broached-tooth design of sintered carbide circular saw, including top surface, two relative sides and inner face and its formation Outer point of a knife, described two sides are provided with groove, inner face described in the trench contact, and a pair of cutter are formed on the inner face Point；The quantity of the groove is set according to the length of circular saw blade saw tooth.

Further, the groove is arranged parallel to the top surface.

Further, the length of the groove is 3/4ths of the lateral width.

The beneficial effects of the utility model：Sawtooth side forms multipair cutting point of a knife, improves cutting effect, and effectively reducing makes The abrasion condition of used time outer point of a knife, increases hard alloy saw blade service life, and side groove can play chip removal simultaneously with radiating Technique effect.

Specific embodiment

With reference to the accompanying drawings and detailed description this utility model is described in further detail.It is of the present utility model Embodiment is given for the sake of example and description, and be not be limited to exhaustively or by this utility model it is disclosed Form.Many modifications and variations are obvious for the ordinary skill in the art.Select and describe to implement Example be in order to more preferably illustrate principle of the present utility model and practical application, and make one of ordinary skill in the art it will be appreciated that This utility model is suitable to the various embodiments with various modifications of special-purpose so as to design.

Embodiment 1

A kind of broached-tooth design of sintered carbide circular saw, as shown in Figure 1, Figure 2, Figure 3 shows, including top surface 101, relative two Individual side 102 and inner face 103 and its outer point of a knife 104 for being formed, described two sides 102 are respectively provided with three groups of grooves 105, the ditch Groove 105 contacts the inner face 103, and a pair of cutting points of a knife 1051 are formed on the inner face 103；The quantity of the groove 105 Set according to the length of circular saw blade saw tooth.

The groove 105 is arranged parallel to the top surface, so preferably can be cut, and improves cutting efficiency；Institute The length for stating groove 105 is 3/4ths of the lateral width, not through the side, is conducive to improving the steady of broached-tooth design It is qualitative.

Obviously, described embodiment is only a part of embodiment of the present utility model, rather than the embodiment of whole. Based on the embodiment in this utility model, this area and those of ordinary skill in the related art are not making creative work Under the premise of the every other embodiment that obtained, should all belong to the scope of this utility model protection.
