Abstract
The invention relates to a making method for cutting sawteeth of a dual metal saw. The making method comprises the following steps of: performing laser cutting or punching or linear cutting forming on a dual metal composite steel band serving as a saw raw material according to the tooth shape; quenching and tempering the cut saw so as to enhance the hardness of a tooth part; grinding and milling a front corner and a rear corner of the thermally processed sawtooth-shaped tooth part so as to form sharp tooth tips; and dividing the teeth. By adopting laser cutting to form the sawtooth, the making method improves the production efficiency, reduces the machining cost and simultaneously solves the problem of overheating of the quenched tooth tips caused by burrs on the tooth tips; furthermore, as the tooth part is separately milled to form the sharp tooth tips, the saw in the use has no run-in period, thereby improving the cutting efficiency of the dual metal saw and prolonging the service lifetime of the dual metal saw.
Description
Technical field
The present invention relates to a kind of manufacture method of bimetal saw blade, especially the sawtooth manufacture method of bimetal saw blade.
Background technology
Common double metallic decoration wire manufacture method be with the bimetallic composite steel band carry out mill teeth (or roll flute), divide tooth, operations (referring to Fig. 1) manufacturing such as Q-tempering heat treatment forms, the sawtooth moulding manufacture method is general to adopt many saw blade raw material overlap mill teeth or roll flute.
The deficiency that adopts above-mentioned sawtooth mill teeth forming manufacture technique to exist has: it is low and expend milling cutter to mill big tooth pitch flute profile efficient, and crown is sharp inadequately, and crown forms burr easily and causes when quenching crown overheated, and the client must carry out break-in when using saw blade.
Summary of the invention
The problem to be solved in the present invention is, in order to overcome defectives such as existing big tooth pitch bimetal saw blade manufacturing cost height, crown are not sharp, proposes a kind of manufacture method of bimetal saw blade sawtooth, has production efficiency height, characteristics that cutting effect is good.
Technical scheme of the present invention is that the processing step of the manufacture method of described bimetal saw blade sawtooth is:
(1) saw blade raw material bimetallic composite steel band is carried out excision forming by flute profile, described excision forming adopts one of following processing method:
A. laser cutting;
B. punch forming;
C. line cutting;
(2) saw blade to excision forming quench, tempering heat treatment, to improve tooth portion hardness;
(3) grinding is carried out at the angle, jagged tooth portion front and back that cuts into after described heat treatment, formed sharp crown;
(4) divide tooth.
Below the present invention made further specify.
Among the present invention, describedly carry out the laser cutting moulding by flute profile and can carry out continuously by beat.
The tooth portion material of described bimetal saw blade can be a high-speed steel.
Said method of the present invention owing to be earlier the processing profile of tooth and the tempering heat treatment of quenching, forms sharp crown to the grinding of tooth portion again, and the contour unanimity of crown and do not have burr need not to carry out break-in during use.And, owing to adopt laser cutting to form sawtooth, improved production efficiency, reduced the machined cost, solved the easy overheated problem of quenching rear tooth point that the crown burr causes simultaneously, and because the independent reconditioning of tooth portion forms sharp crown, saw blade need not break-in when using, and can improve the cutting efficiency and the service life of bimetal saw blade.
As known from the above, the present invention is a kind of manufacture method of bimetal saw blade sawtooth, this method production efficiency height, machined cost are low, solved the easy overheated problem of quenching rear tooth point that the crown burr causes simultaneously, saw blade need not break-in when using, and has improved the cutting efficiency and the service life of bimetal saw blade.
Description of drawings
Fig. 1 is the process chart that prior art is produced bimetal saw blade;
Fig. 2 is a kind of embodiment process chart that the present invention produces bimetal saw blade.
The specific embodiment
Embodiment 1:Manufacture method with described bimetal saw blade sawtooth is produced the wide saw blade of 54mm, and raw material are that the back is that Special spring steel, tooth portion are the bimetallic composite steel band of high-speed steel, and width is 54mm; Tooth portion can adopt the M42 high-speed steel; Production craft step is:
(1) saw blade raw material bimetallic composite steel band is carried out the laser cutting moulding by flute profile:
Cut profile of tooth with laser cutting machine, cut required profile of tooth by numerical control programming; Carry out the laser cutting moulding of flute profile continuously by beat, every beat cutting 5 or 5 above tooth pitches, per minute cutting 5-8 rice, crown forms the circular arc of 0.05mm-0.1mm;
Laser cutting device can be selected the logical fast Trulaser3030 laser cutting machine of Germany for use, or Switzerland's hundred super laser cutting machines, or other suitable laser cutting machine;
(2) saw blade to excision forming quench, tempering heat treatment, to improve tooth portion hardness:
Adopt the continuous quenching tempering; 1190 ℃-1230 ℃ of hardening heats, temperature retention time 60 seconds-90 seconds; 600 ℃-630 ℃ of temperatures, temperature retention time 360 seconds-420 seconds, tempering is 3 times continuously, more than the hardness HRC68 of tooth portion;
(3) grinding is carried out at angle before and after the jagged tooth of cutting into after the described heat treatment portion respectively and formed sharp crown, reconditioning quality is 0.05-0.1mm, can grind anterior angle earlier, also can grind relief angle earlier;
(4) divide tooth:, be finished product after dividing tooth with conventional method by a minute tooth amount requirement.
