Abstract
The utility model relates to a saw blade which mainly solves the problems of high possibility of binging and breaking and low efficiency when the existing saw blade is used for sawing. Sawteeth are divided into first sawteeth and second sawteeth; the first sawteeth and the second sawteeth are arrayed on the edge of one side of a saw body in a staggered manner; the width of a tooth crest on each first sawtooth is 1.1-3.5 times greater than that of a saw back of the saw body; the width of a tooth crest on each second sawtooth is less than that of the tooth crest on each first sawtooth; the width of a saw surface formed by each second sawtooth and the saw body is greater than that of a saw surface formed by each first sawtooth and the saw body; a notch is formed at the top of each second sawtooth; and a carbide blade is arranged on each notch. The saw blade has the characteristics of convenient material change, high cutting efficiency and long service life.
Description
Technical field
The utility model relates to a kind of saw blade.
Background technology
Sawing is the main method of decomposing timber, is again the first operation of timber work.Straight blade or bands for band are the sawing instruments of commonly using.Saw blade is generally all made by high-carbon steel, improves hardness by the saw blade integral quenching, and the hardness of saw blade integral body is all the same like this, when cutting timber, when sawtooth enters timber inside, the timber of saw kerf wall both sides, under the effect of land, temporarily compress in the saw kerf wall, once land passes through, resilience immediately, compress denticle, along with saw kerf is goed deep into, clamp again saw body, i.e. binding phenomenon.for fear of binding, common are and dial curved to saw body both sides with the sawtooth crown is staggered, make saw kerf width that land cuts out greater than saw body thickness, when denticle and saw pass through in wider saw kerf, just unlikely by the timber extruding of saw kerf wall both sides, the binding phenomenon obviously descends, but due to being interspersed of crown, the cutting edge of sawtooth just tilts to both sides, the saw power of use on saw blade is disperseed greatly, stock-removing efficiency obviously reduces, and general high-speed steel is subject to cost and toughness reguirements, sawtooth hardness is very limited, stressed excessive easily cause cracked, the defectives such as service life is short.
The utility model content
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of saw blade, mainly solves existing saw blade and exists easy binding, inefficiency to reach easily cracked problem when sawing.
the technical solution of the utility model is: a kind of saw blade, comprise saw body and sawtooth, it is characterized in that: described sawtooth divides the first sawtooth and the second sawtooth, described the first sawtooth and the second sawtooth are staggered on the edge of saw body one side, the width of the tooth top on described the first sawtooth be saw hump width with it 1.1-3.5 doubly, addendum width on described the second sawtooth is less than the addendum width on the first sawtooth, the saw face width degree that described the second sawtooth and saw body consist of is greater than the saw face width degree of described the first sawtooth with saw body formation, described the second sawtooth top is provided with a breach, be provided with carbide chip on this gap position.
Addendum width on described the second sawtooth be saw hump width with it 1-2.5 doubly.
Described carbide chip welds mutually with the second sawtooth.
Described the first sawtooth is the inverted trapezoidal cross section with the saw blade cross section that the saw body consists of.
The beneficial effects of the utility model: owing to taking such scheme, saw blade of the present utility model when sawing, have reload conveniently, stock-removing efficiency is high, the characteristics of long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of A-A face in Fig. 1.
In figure, saw body 1, the first sawtooth 2, the second sawtooth 3, carbide chip 31.
The specific embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
shown in figure, this saw blade, comprise saw body 1 and sawtooth, described sawtooth divides the first sawtooth 2 and the second sawtooth 3, described the first sawtooth 2 and the second sawtooth 3 are staggered on the edge of saw body 1 one sides, the width of the tooth top on described the first sawtooth 2 be hump width on saw body 1 1.1-3.5 doubly, addendum width on described the second sawtooth 3 is less than the addendum width on the first sawtooth 2, the saw face width degree that described the second sawtooth 3 and saw body 1 consist of is greater than the saw face width degree of described the first sawtooth 2 with saw body 1 formation, described the second sawtooth top is provided with a breach, be provided with carbide chip 31 on this gap position.Addendum width on described the second sawtooth 3 be hump width on saw body 1 1-2.5 doubly.Higher than being interspersed of the first sawtooth, when sawing, the carbide chip on the second sawtooth carries out fly-cutting to material, has greatly strengthened stock-removing efficiency by the second sawtooth, and the chip resistant effect, has extended the service life of saw blade.The gap of larger the first sawtooth of width after to the second saw cut expanded processing, and the addendum width by sawtooth only needs slightly to tilt can make saw blade and feed separation during feeding greater than the setting of hump width, has the effect easily of reloading.
Described carbide chip 31 welds mutually with the second sawtooth 3, have easy for installation, characteristics firmly.
Described the first sawtooth 2 is the inverted trapezoidal cross section with the saw blade cross section that saw body 1 consists of, and cut stressed evenly, has effectively increased service life of saw blade.
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 (4)
