Abstract
The utility model provides a kind of diamond saw blade for cutting aluminium section bar, comprise matrix, sawtooth and cutter head, described sawtooth is uniformly distributed in the outer rim of described matrix, first joint face of described cutter head and the second joint face are fixed on the both sides, top of each described sawtooth respectively in the mode of soldering, form two-sided welding structure; The tooth top of described cutter head is arcuate structure.Arc tooth top makes saw blade transition in cutting process mild, can not cause the scuffing of cutting surfaces, significantly improve cut quality.
Description
Technical field
The utility model relates to materials processing field of tool, is specifically related to a kind of diamond saw blade for cutting aluminium section bar.
Background technology
Industrial aluminum profile a kind ofly therefore for the processing of aluminium section bar, has comparatively strict requirement for comparatively accurate occasion (as mounting) in fracture morphology and cutting effect etc., stricter to its requirement.
Although at present for the polycrystalline diamond rack saw sheet processing aluminium section bar have hardness high, cut sharp, the nonabradable advantage of sawtooth, but the impact resistance of the cutter head on sawtooth is in urgent need to be improved, owing to belonging to severe interrupted cut to aluminium section bar cutting process, therefore the sawtooth of saw blade occurs collapsing the phenomenon such as tooth, broken teeth possibly; In addition, existing sawtooth tooth top is planar structure, often occurs the phenomenon that section out-of-flatness is jagged affecting cut quality to a certain extent.
Utility model content
In view of this, the utility model provides a kind of diamond saw blade for cutting aluminium section bar, is intended to improve the cut quality of saw blade for aluminium section bar.
The technical solution adopted in the utility model is specially:
A kind of diamond saw blade for cutting aluminium section bar, comprise matrix, sawtooth and cutter head, described sawtooth is uniformly distributed in the outer rim of described matrix, first joint face of described cutter head and the second joint face are fixed on the both sides, top of each described sawtooth respectively in the mode of soldering, form two-sided welding structure; The tooth top of described cutter head is arcuate structure.Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the central angle that the circular arc line of described arcuate structure is corresponding is 160 ~ 180 °.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the central angle that the circular arc line of described arcuate structure is corresponding is 175 °.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the radius that the circular arc line of described arcuate structure is corresponding is 2 ~ 2.5mm.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the radius that the circular arc line of described arcuate structure is corresponding is 2.1mm.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the length of described sawtooth is 3 ~ 5mm.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the length of described sawtooth is 3.5 ± 0.1mm.
Above-mentioned for cutting in the diamond saw blade of aluminium section bar, the angle that described first joint face and described second joint face are formed is 60 ~ 70 °.
The beneficial effect that the utility model produces is:
The cutter head of diamond saw blade of the present utility model realizes being connected with sawtooth by the mode of two-sided soldering, and under the prerequisite ensureing cutting edge sharpness, the connected mode of this slip-off preventing of cutter head significantly increases the service life of saw blade entirety;
Compare to the tooth top of the planar junction shape structure formula of traditional sawtooth, arc-shaped gear of the present invention withstands on because transition is round and smooth, uniform force in cutting process, and therefore can not scratch cut surface, can make the smooth impulse-free robustness of section, cut quality is obviously improved.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, more completely the utility model can be understood better.Accompanying drawing described herein is used to provide further understanding of the present utility model, and embodiment and explanation thereof, for explaining the utility model, are not formed improper restriction of the present utility model.
Fig. 1 is the perspective view (locally) of a kind of diamond saw blade for cutting aluminium section bar of the utility model;
Fig. 2 is the cutter head of a kind of diamond saw blade for cutting aluminium section bar of the utility model and the syndeton schematic diagram of sawtooth.
In figure: 1, matrix 2, sawtooth 3, cutter head 31, first joint face 32, second joint face.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of diamond saw blade for cutting aluminium section bar as shown in Figure 1, mainly comprise matrix 1, be uniformly distributed in the sawtooth 2 of matrix outer rim and be fixed on the cutter head 4 of sawtooth, the edge of matrix 1 is inwardly cut with the 3-8 bar line of rabbet joint (not marking) for noise reduction, the length of sawtooth is 3-5mm, is preferably 3.5 ± 0.1mm.Further as shown in Figure 2, two joint faces (31,32) of cutter head 3 are fixed on the top of sawtooth 2 in the mode of soldering, form two-sided welding structure, preferred as one, joint face (31,32) forms the sharp angle α (as 67 °) of 60 ~ 70 °.
And in working On The Sawteeth Shape in saw blade of the present utility model, the tooth top structure of cutter head 3 is optimized for arcuate structure by current planar structure, with further reference to Fig. 1, the central angle that the circular arc line of arcuate structure is corresponding is 160 ~ 180 ° (as 175 °), corresponding radius is 2 ~ 2.5mm (as 2.1mm).
Because arc surface does not have corner angle in cutting process, the contact of gentle transition formula can not cause scuffing to cutting surfaces, significantly improves cut quality.
Below explain embodiment of the present utility model by reference to the accompanying drawings, accompanying drawing is herein used to provide further understanding of the present utility model.Obviously; the foregoing is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any be to one skilled in the art can expect easily, do not depart from change of the present utility model or replacement in fact, be also all included within protection domain of the present utility model.
