Description
Technical field
The present invention relates to a kind of ultrafine grain hard alloy bimetallic strip saw blade.
Background technology
At present; prior art is applied to the saw blade of metal, nonmetallic materials Cutting indexes; generally use the various ways such as strip, band shape, plate-like; but no matter that form; they all belong to the same one that sawtooth combines with body; this version; although there is certain advantage, as simple, convenient in manufactured processing, but often can not meet the demand of sawing difficult-to-machine material; the saw of this integral structure; often can make hackle distortion, rust, chip removal difficulty, sawing is crooked, and processing effect is poor; efficiency is low, and service life is short.
Bi-metal bandsaw blades because of its have efficiently, the feature of low energy, energy-conservation, material-saving and by industry extensive uses such as machine-building, metallurgy, chemical industry, military projects.It is welded through vacuum electronic with ultra high strength alloy steel matrix by cutting edge high-speed steel sawtooth, through the composite saw cutting tool that a series of hot and cold processing technology manufactures; Existing bi-metal bandsaw blades, its teeth portion cutting power, wearability are better, this is mainly because the selection of existing heat treatment process parameter is determined for teeth portion high speed steel material, and saw blade matrix alloy steel is under this technological specification process, its fatigue performance greatly reduces, when in so just causing using, minimum, the performance of teeth portion wearing and tearing is intact, matrix occur crackle even phenomenon of rupture, produce teeth portion and matrix and to lose efficacy nonsynchronous problem, affect the service life of bi-metal bandsaw blades, waste raw material.
Summary of the invention
The object of this invention is to provide a kind of ultrafine grain hard alloy bimetallic strip saw blade, to overcome prior art above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
A kind of ultrafine grain hard alloy bimetallic strip saw blade, comprise saw blade body, described saw blade body upper part is equidistantly provided with some crown bodies, crown groove is provided with in the middle part of described crown body, carbide alloy crown is welded with and adjacent two carbide alloy crowns are located at the both sides of saw blade body upper part respectively in described crown groove, one of them carbide alloy crown is welded on one end of corresponding crown groove, another carbide alloy crown is welded on the other end of corresponding crown groove, and the lateral surface of carbide alloy crown protrudes the lateral surface of saw blade body.
Beneficial effect of the present invention is: economical and practical, substantially increases production efficiency, reduces machined, manually, and the cost of electric energy; Crown is welded with ultra micron carbide alloy, can reach the object being with soft anticracking; Crown is comparatively hard, durable in use, crown firmly not easily carnassial tooth, fall tooth, long service life; Without the need to break-in during use, the cutting efficiency of bi-metal bandsaw blades and the service life of sawtooth can be improved, make Reducing Cost in Enterprises.

Detailed description of the invention
As shown in figs. 1-7, ultrafine grain hard alloy bimetallic strip saw blade described in the embodiment of the present invention, comprise saw blade body 1, described saw blade body 1 top is equidistantly provided with some crown bodies 3, crown groove 4 is provided with in the middle part of described crown body 3, carbide alloy crown 2 is welded with and adjacent two carbide alloy crowns 2 are located at the both sides on saw blade body 1 top respectively in described crown groove 4, one of them carbide alloy crown 2 is welded on one end of corresponding crown groove 4, another carbide alloy crown 2 is welded on the other end of corresponding crown groove 4, and the lateral surface of carbide alloy crown 2 protrudes the lateral surface of saw blade body 1.
The manufacture method of the saw blade sawtooth of the tungsten carbide button of sawing big-diameter wood (diameter 600-1500mm), saw blade former bar Jin Hang temper fire tempering 2 times, its hardness and toughness is made to reach optimum state, winding is adopted automatically to connect the die-cut sawtooth of punching method again, the method is than existing milling, the method of Linear cut or laser cutting wants fast 50-100 doubly, per minutely can make 180 teeth, economical and practical.Substantially increase production efficiency, reduce the cost of machined, artificial and electric energy, then through fibre weldering mode, the ultra micron carbide alloy fibre adopting hardness to reach 92 ° is soldered on die-cut good crown, reaches band soft anticracking, the long-lived effect of denticle.Adopt unique mosaic mode: rush recessed 60 percent tungsten carbide button of place crown at belt body crown position, leave 40 percent mother metal protection carbide alloy crown, make the more firm not easily carnassial tooth of crown, fall tooth.Adopt the method can make double the service life of band saw above.Carry out the four sides reconditioning of pipeline system monodentate again, its precision reaches 0.002mm, without the need to break-in during use, just can improve the cutting efficiency of bi-metal bandsaw blades and the service life of sawtooth, make Reducing Cost in Enterprises.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
