Abstract
The utility model relates to a double metal saw blade which mainly solves the problems that an existing saw blade is easy to abrade and cutting metal materials is difficult in the process of use. A strip-shaped clamping groove is formed in one side of a saw blade body. A hard alloy sheet is arranged in the strip-shaped clamping groove. Sawteeh are arranged at an edge of the hard alloy sheet. The double metal saw blade has the advantages of being good in cutting and bearing capacity and long in service life.
Description
Technical field
The utility model relates to a kind of bimetal saw blade.
Background technology
Saw blade is widely used in a plurality of industries such as machine-building, timber processing, metallurgy, chemical industry, military project.Saw blade divides again frame saw blade and bands for band, and frame saw blade is not only thin but also long, Yi Bian the symmetrical saw that is shaped with several sawtooth of hump, this saw is arranged on and carries out sawing workpieces on the buck saw lathe; Bands for band is not only thin but also long, one side the band saw that is shaped with several sawtooth of hump symmetry is arranged on and carries out sawing work on band-saw machine tool.
Existing saw blade is made of the sawtooth of saw blade body, in order to realize better processing characteristics, the saw blade body requires to have higher toughness, sawtooth requires to have higher hardness, due to the restriction that is subject to cost and toughness reguirements, saw blade is generally all made by high-carbon steel, improve hardness by the saw blade integral quenching, the hardness of saw blade integral body is all the same like this, so the sawtooth hardness of existing this saw blade is limited, stock-removing efficiency is low, affect cutting quality, service life is short, is difficult to use in cutting metal material, restricted application.
The utility model content
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of bimetal saw blade, mainly solves existing saw blade and exists in use easy to wear and the cutting metal material hard problem.
The technical solution of the utility model is: a kind of bimetal saw blade, comprise saw body and sawtooth, it is characterized in that: a side of described saw body is provided with the strip draw-in groove, is provided with hard metal tip in described strip draw-in groove, and described sawtooth is arranged on the edge of hard metal tip one side.
Described hard metal tip welds mutually with described strip draw-in groove.
The hardness of described hard metal tip is HRC65-80.
The beneficial effects of the utility model: owing to taking such scheme, it is good that bimetal saw blade of the present utility model has the cutting bearing capacity, the characteristics of long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, saw body 1, hard metal tip 2, sawtooth 3.
The specific embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
Shown in figure, this bimetal saw blade comprises saw body 1 and sawtooth 3, and it is characterized in that: a side of described saw body 1 is provided with the strip draw-in groove, is provided with hard metal tip 2 in described strip draw-in groove, and described sawtooth 3 is arranged on the edge of hard metal tip 2 one sides.The saw body of saw blade and the axial limiting of strip draw-in groove and hard metal tip are partly the integrated punching moulding, has larger bearing capacity, hard metal tip passes through the laser weld moulding with the saw body, make sawtooth with the Hardmetal materials that adopts high rigidity metalwork is carried out sawing, has good comprehensive cutting ability, be applicable to cut the metal materials such as solid round steel, tubing, shape material and stainless steel, steel alloy, mould steel, the saw blade antiwear property is strengthened greatly, has the cutting bearing capacity good, the characteristics of long service life.
Weld mutually as preferred described hard metal tip 2 and described strip draw-in groove, connect in the mode of draw-in groove welding, have easy for installation, the characteristics of firm welding.
Hardness as preferred described hard metal tip 2 is HRC65-80, has rub proofness high, the effect that bearing capacity is good.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
Claims (3)
1. a bimetal saw blade, comprise saw body and sawtooth, and it is characterized in that: a side of described saw body is provided with the strip draw-in groove, is provided with hard metal tip in described strip draw-in groove, and described sawtooth is arranged on the edge of hard metal tip one side.
2. bimetal saw blade according to claim 1, it is characterized in that: described hard metal tip welds mutually with described strip draw-in groove.
