The chamfer also can be processed into in the tooth root both sides of sword tooth, and the chamfer part is put the first edge on a knife or a pair of scissors. The utility model discloses in the process of cutting downwards, the sword tooth is from up rotating down, and the tooth root of sword tooth can touch the saw kerf that has just sawed, because the tooth root is very smooth through putting the first edge on a knife or a pair of scissors, can not rub to the saw limit, makes the saw limit more smooth, avoids collapsing the limit.
Description
Technical field
This utility model relates to cutting tool, especially polycrystalline diamond saw blade.
Background technology
Saw blade is as a kind of cutting tool, including discoideus supporter and the multiple cutters tooth being located at supporter circumferential edge.Most cutters tooth is also machined with anterior angle inclination angle, so that what cutter tooth and machined material adapted.Saw blade is installed on processing unit (plant), carries out materials processing by rotary cutting.Easily there is out-of-flatness in the facet that saw blade cuts out, occurs that turnup, burr etc. collapse limit phenomenon.
In order to solve the problems referred to above, Chinese utility model patent CN201776524U discloses a kind of Special alloy saw blade for cutting aluminium materials, and cutter tooth uses stepped tooth and the form of flat tooth cross arrangement, and stepped tooth height is higher than flat tooth height.Wherein, stepped tooth plays cutting action, and flat tooth plays correction, optimizes the effect of saw kerf, improves the fineness of saw kerf while ensureing cutting efficiency.In technique scheme, although flat tooth can reach to revise the effect of facet to a certain extent, but when facet contacts with cutter tooth root, can produce friction, causes facet to be ground coarse.Visible, there is following defect in existing saw blade: revised facet is easily rubbed by cutter tooth root, and the fineness causing saw kerf is not high enough.
Utility model content
The purpose of this utility model is to provide polycrystalline diamond saw blade, it is possible to prevents saw kerf from producing friction with cutter tooth, prevents from collapsing limit, and simple in construction, easy to process.
In order to achieve the above object, the following technical scheme of this utility model offer:
Polycrystalline diamond saw blade, including discoideus supporter and cutter tooth, described cutter tooth is arranged on the circumferential edge of described supporter, and the tooth root both sides of described cutter tooth are through putting the first edge on a knife or a pair of scissors process.Saw blade is when cutting, and material is cut open by the tip portions of cutter tooth, and the saw edge of material the side of cutter tooth and moves to tooth root direction.When saw limit is with root contact, the tooth root unusual light put the first edge on a knife or a pair of scissors, will not rub to saw limit, make saw marginal ray sliding, it is to avoid to collapse limit, improve the effect of sawing.
In a preferred embodiment, the tooth root both sides of described cutter tooth are chamfering, and described chamfering is chamfering of putting the first edge on a knife or a pair of scissors.Tooth root both sides carry out chamfered, reduce its stress and concentrate, strengthen the intensity of tooth root both sides.
In a preferred embodiment, described cutter tooth is flat tooth, stepped tooth, or flat tooth and stepped tooth cross arrangement.Cutter tooth can all use flat tooth, it is also possible to all uses stepped tooth, it would however also be possible to employ flat tooth and stepped tooth cross arrangement.
In a preferred embodiment, except the connecting portion of described cutter tooth Yu described supporter, other outline limits of described cutter tooth are through putting the first edge on a knife or a pair of scissors process.
In a preferred embodiment, the thickness range of described supporter is 1.0mm～6.0mm, and the thickness range of described cutter tooth is 1.2mm～7.0mm.
In a preferred embodiment, the thickness range of described supporter is 2.0mm～4.0mm, and the thickness range of described cutter tooth is 3.0mm～5.0mm.
In a preferred embodiment, when described cutter tooth is flat tooth and stepped tooth cross arrangement, described stepped tooth top is at least above described flat tooth top 0.25mm.
The beneficial effects of the utility model are:
This utility model is in the process of cutting downwards, and cutter tooth rotates from the bottom up, and the tooth root of cutter tooth can touch the saw kerf just cut, owing to tooth root is through putting the first edge on a knife or a pair of scissors, unusual light, will not rub to saw limit, make saw limit more smooth, it is to avoid to collapse limit.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Shown in Fig. 1-2, the polycrystalline diamond saw blade that the present embodiment provides, including discoideus supporter 1 and cutter tooth 2.The circumference of supporter 1 is processed into sawtooth 11, and sawtooth 11 is equably in the circle distribution of supporter 1.The surface soldered cutter tooth 2 of sawtooth 11.The thickness range of supporter 1 is 1.0mm～6.0mm, and the thickness range of cutter tooth 2 is 1.2mm～7.0mm.The saw blade of this thickness can be suitable for the sheet material that cutting thickness is bigger.Preferably, the thickness of supporter 1 uses 2.0mm～4.0mm, and the thickness of cutter tooth 2 uses 3.0mm～5.0mm.Centre bore 12 is offered at the center of supporter 1, offers installing hole 13 around centre bore 12.Also offering four expansion slots 14 on supporter 1, the expansion slot 14 middle part between two sawtooth 11 extends along centre bore 12 direction.Four expansion slots 14 are question mark shape, and the circumferential edge evenly along supporter 1 is distributed.
Such as Fig. 3, the cutter tooth 2 in the present embodiment is flat tooth.The tooth root both sides 21 of cutter tooth 2, through putting the first edge on a knife or a pair of scissors processs, make tooth root both sides 21 avoid and saw limit to produce friction, prevent from sawing collapse while.Such as Fig. 4, chamfering can be processed in the tooth root both sides 21 of cutter tooth 2, and this chamfered part carries out process of putting the first edge on a knife or a pair of scissors.The position 20 being connected with supporter 1 except cutter tooth 2, the whole outline limit of cutter tooth 2 has all carried out process of putting the first edge on a knife or a pair of scissors, and produces friction with the side and root ensureing cutter tooth 2 all without to saw limit.
Such as Fig. 5, in one embodiment, cutter tooth 2 is stepped tooth, and chamfering is processed in tooth root both sides 21, and the part put the first edge on a knife or a pair of scissors is whole chamfering.Chamfered can reduce the stress of tooth root both sides 21 and concentrate, and strengthens its intensity.Tooth root can not also be carried out chamfering, directly put the first edge on a knife or a pair of scissors.
In one embodiment, cutter tooth 2 can also use the mode of flat tooth and stepped tooth cross arrangement, and stepped tooth top is at least higher 0.25mm than flat tooth top.And, process of putting the first edge on a knife or a pair of scissors all through in the tooth root both sides 21 of all of cutter tooth 2, prevent cutter tooth 2 to saw limit produce friction, prevent saw collapse while.In order to improve the efficiency of chip removal, such as Fig. 2, slope can also be processed in the junction 10 between two sawtooth 11.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with scope of the claims.
