Abstract
The utility model discloses a high-speed steel circular saw blade. Saw teeth 2 of an integral high-speed steel circular saw blade is subjected to setting before quench hardening and are divided into left teeth and right teeth, so that width W of a saw cut is greater than thickness B of a saw body; and meanwhile, a certain side blade back angle is formed during setting. An inclined blade grinding mode is adopted during blade grinding after thermal treatment, so that a certain side blade front angle psi is formed; rear surfaces of the teeth are ground into folding back outlines; and a certain top blade rear angle alpha is formed. Certain top blade front angle gamma and top blade inclination angle lambda are also formed after the circular saw blade is subjected to the blade grinding. A proper figure wedge angle beta is adopted; and a transition circular arc R with a certain radius is formed at the bottom of a tooth space. Through the measures, sharpness, saw cutting efficiency and strength rigidity of the integral high-speed steel circular saw blade are improved, and service life is prolonged.
Description
Technical field: the utility model relates to a kind of high-speed steel saw blade, specifically a kind of monoblock type high-speed steel saw blade with material toggling tooth.
Background technology: the high-speed steel saw blade that uses is divided into anodontia and tooth two big classes is arranged at present, and the friction-saw sheet is actually a kind of circular knife, is used for cutting softer things such as paper, plastics, veneer.Have tooth high-speed steel saw blade to be also referred to as metal saw, divide monoblock type and tooth-like two classes of weldering, monoblock type high-speed steel saw blade is made by the monoblock steel plate.The sawtooth that welds tooth-like high-speed steel saw blade is tooth piece independently, is soldered to saw on one's body with laser or soldering processes, technology cost height, and fall tooth easily, influence operator's personal safety.Existing monoblock type high-speed steel saw blade is regardless of left and right tooth, does not have the saw material, straight sharpening, and the anterior angle of side edge and relief angle all are zero, and sharpness is poor, and frictional force is big during sawing, heating easily, cutting-rate is low, and saw life is short.
Summary of the invention: the purpose of this utility model provides a kind of low cost of manufacture, sharpness is good, cutting-rate is high, the monoblock type high-speed steel saw blade of long service life.
The purpose of this utility model is achieved in that carried out material toggling to the sawtooth of monoblock type high-speed steel saw blade before quench hardening, be divided into left tooth and right tooth, made the saw kerf width greater than saw body thickness, formed certain side edge relief angle simultaneously during material toggling.Adopt bevel grinding sword mode after the heat treatment during sharpening, form certain side edge anterior angle, fold back contour is worn in the tooth back, and certain top relief angle is arranged.Form certain top angle of cutting edge and top cutting edge inclination behind the saw blade sharpening.Adopt the suitable profile angle of wedge, be provided with the transition arc of certain radius at the bottom of the teeth groove.
Because sawtooth carried out material toggling, be divided into left tooth and right tooth, the saw kerf width is greater than saw body thickness, thereby reduced the frictional force of saw body and saw kerf wall, improved cutting-rate, alleviates the heating of saw blade and saw kerf wall, prolonged the service life of saw blade.Owing to adopted bevel grinding sword mode, formed certain side edge anterior angle, thereby improved the sharpness of side edge greatly, improved cutting-rate, reduce the roughness of saw kerf wall, also alleviated the heating of saw blade and saw kerf wall simultaneously, prolonged the service life of saw blade.Owing to form certain top angle of cutting edge and top cutting edge inclination behind the saw blade sharpening, improved the sharpness of top sword and crown, improved cutting-rate.Owing to adopt the suitable profile angle of wedge, and be provided with the transition arc of certain radius at the bottom of the teeth groove, make sawtooth have enough strength and stiffness, between cog has enough chip spaces simultaneously, guarantees normally carrying out of sawing process.
Description of drawings: the utility model is further specified below in conjunction with drawings and Examples.
Fig. 1 represents the front view of material toggling tooth monoblock type high-speed steel saw blade.
Fig. 2 represents the right side cross-sectional view of material toggling tooth monoblock type high-speed steel saw blade.
Fig. 3 represents that the A of front view is to partial enlarged drawing.
Fig. 4 represents the tooth portion partial enlarged drawing of right side cross-sectional view.
Fig. 5 represents the tooth portion partial enlarged drawing of front view.
Among the figure: 1, arc radius at the bottom of saw body 2, sawtooth 3, installing hole 4, side edge 5, top sword 6, crest top land α, top relief angle β, profile wedge angle gamma, top angle of cutting edge ψ, side edge anterior angle λ, top cutting edge inclination B, saw body thickness W, saw kerf width L, folding back of the body length R, the teeth groove
The specific embodiment: among Fig. 1-Fig. 5, monoblock type high-speed steel saw blade is made up of saw body 1 and many sawtooth 2, and there is installing hole 3 in the central authorities of saw body 1.Sawtooth 2 carried out material toggling before quench hardening, be divided into left tooth and right tooth, made the saw kerf width W greater than saw body thickness B, formed certain side edge relief angle simultaneously during material toggling.Adopt bevel grinding sword mode after the heat treatment during sharpening, form certain side edge anterior angle ψ, the numerical value of ψ is 5 °-45 °.Fold back contour is worn in the tooth back, and folding back of the body length L is 1mm-5mm.Certain top relief angle α is arranged, and the numerical value of relief angle α is 5 °-25 °.Form certain top angle of cutting edge γ and top cutting edge inclination λ behind the sharpening, the numerical value of top angle of cutting edge γ is 3 °-25 °, and the numerical value of top cutting edge inclination λ is 2 °-15 °.The numerical value of profile angle of wedge β is 25 °-45 °, and the numerical value of arc radius R is 0.8mm-8mm at the bottom of the teeth groove.
Because sawtooth 2 carried out material toggling, be divided into left tooth and right tooth, the saw kerf width W is greater than saw body thickness B, thereby reduced the frictional force of saw body B and saw kerf wall, improved cutting-rate, alleviates the heating of saw blade and saw kerf wall, prolonged the service life of saw blade.Owing to adopted bevel grinding sword mode, formed certain side edge anterior angle ψ, thereby improved the sharpness of side edge 4 greatly, improved cutting-rate, reduce the roughness of saw kerf wall, also alleviated the heating of saw blade and saw kerf wall simultaneously, prolonged the service life of saw blade.Because fold back contour is worn in the tooth back, the numerical value of profile angle of wedge β is 25 °-45 °, and certain arc radius R is arranged at the bottom of the teeth groove, makes sawtooth 2 have enough strength and stiffness, and between cog has enough chip spaces simultaneously, guarantees normally carrying out of sawing process.Because certain top angle of cutting edge γ and top cutting edge inclination λ are arranged, improved the sharpness of top sword and crown, improved cutting-rate.
