Abstract
The utility model provides a double-metal band saw blade with a protection layer and is aimed at solving the problems that the conventional saw blade gets broken easily and saw teeth thereof are often excessively worn. The double-metal band saw blade comprises a saw blade body and saw teeth disposed on one side of the saw blade body continuously. Each saw tooth comprises a tooth tip part and a tooth root part. The saw blade body is made of alloy spring steel and the tooth tip parts of the saw teeth are made of powder metallurgy high speed steel. The saw teeth are provided with TICN coatings. Through combination of two kinds of metal of different materials, both the tenacity of the saw blade and the rigidity of the saw tooth part are guaranteed. The saw teeth are provided with the TICN coatings, so that the wear of the saw teeth is prevented and the service lifetime of the saw blade is prolonged. The double-metal band saw blade has the advantages of stable and reliable quality, high adaptability, hardness resistance, fatigue resistance, long service life and high accuracy and guarantees smoothness and cleanness of saw-cut surfaces.
Description
Technical field
The utility model relates to a kind of saw blade, is specifically related to a kind of bi-metal bandsaw blades that is coated with matcoveredn.
Background technology
Saw blade is mainly used in the cutting to metal, nonmetallic materials.Saw blade is combined by saw blade and sawtooth, and wherein saw blade is in the process of cutting, and sawtooth has played crucial effect, and it requires sawtooth to have certain hardness, and the toughness that fractures to saw blade for fear of saw blade also has certain requirement.The saw blade that is mainly used in cutting metal material that uses in the market, because of sawtooth hardness not or saw blade toughness inadequate, saw blade fracture or sawtooth easily occur and produce and draw the various problems such as tooth, run in cutting process, thereby reduce the service life of saw blade.
Summary of the invention
In background technology, saw blade easily ruptures in order to solve, the easy excessive wear problem of sawtooth, and the utility model provides a kind of bi-metal bandsaw blades that is coated with matcoveredn.
The technical solution of the utility model is: a kind of bi-metal bandsaw blades that is coated with matcoveredn; comprise the saw blade body and be located at the saw blade body one continuously arranged sawtooth of lateral edges; described sawtooth comprises crown section and tooth root section; described saw blade body adopts alloy spring steel; the crown section of described sawtooth adopts PM HSS, and described sawtooth is provided with the TICN coating.
Advance a kind of improvement as of the present utility model, described crown section and tooth root section are the integral type structure by electron beam welding.
Advance a kind of improvement as of the present utility model, the tooth root section of described sawtooth and saw blade body are the integral type structure.
The beneficial effects of the utility model are, adopt the metal of two kinds of unlike materials to combine, and the toughness that has namely guaranteed saw blade has guaranteed again the hardness of crown section.Simultaneously, scribble the TICN coating on sawtooth, can prevent the wearing and tearing of sawtooth, extended the service life of saw blade.And the utility model also has steady quality, reliable, strong adaptability, anti-hard, endurance, long service life, sawing any surface finish, precision advantages of higher.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In figure, 1, the saw blade body; 2, sawtooth; 21, crown section; 22, tooth root section; 23, TICN coating.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
by shown in Figure 1, a kind of bi-metal bandsaw blades that is coated with matcoveredn, comprise saw blade body 1 and be located at the saw blade body 1 one continuously arranged sawtooth 2 of lateral edges, described sawtooth 2 comprises crown section 21 and tooth root section 22, described saw blade body 1 adopts alloy spring steel, the crown section 21 of described sawtooth 2 adopts PM HSSs, certainly also can adopt the materials such as M42 high-speed steel (the high cobalt toughness of W2Mo10Cr4Co8 high-speed steel) in the utility model mesostyle section 21, it is Titanium Carbonitride that described sawtooth 2 is provided with TICN coating 23(, titanium carbonitride coating).。Specifically, described crown section 21 and tooth root section 22 are the integral type structure by electron beam welding, and the tooth root section 22 of described sawtooth 2 is the integral type structure with saw blade body 1.Adopt the metal of two kinds of unlike materials to combine, the toughness that has namely guaranteed saw blade has guaranteed again the hardness of crown section.Simultaneously, scribble the TICN coating on sawtooth, can prevent the wearing and tearing of sawtooth, extended the service life of saw blade.And the utility model also has steady quality, reliable, strong adaptability, anti-hard, endurance, long service life, sawing any surface finish, precision advantages of higher.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
