Abstract
The utility model provides a cutting saw blade of high-speed tool steel, belonging to mechanical cutting tools. The material of the cutting saw blade of high-speed tool steel is high-speed tool steel. The utility model is characterized in that the saw blade is thin; the tooth tip point of each saw tooth is milled with an inclined plane. The cutting saw blade of high-speed tool steel has an optimum effect of cutting pipe materials with thin walls and particularly for cutting copper pipe materials with thin walls, being an ideal cutting tool at home.
Description
The utility model provides a kind of cutting tools, particularly can the sawing metal and the high-speed tool steel cast-cutting saw slice of slim tubing of non-ferrous metal or section bar.
At present, the various cutting tools of domestic production all are not suitable for the slim pipe of sawing, section bar, the common saw blade that replaces using can make tube wall surface produce concave surface, and the saw kerf rough surface is uneven, and saw kerf leaves burr, promptly do not conform to technological requirement, the requirement of can't ensuring the quality of products, the useless raw material of wave again.
The purpose of this utility model is that a kind of high-speed tool steel cast-cutting saw slice will be provided, and it is applicable to that its linear velocity of high-speed cutting is 50 meter per seconds, and it is sawing metal and non-ferrous metal thin-wall pipes and section bar effectively.Reach that sawing is sharp, saw kerf is not stayed smear metal and burr, can not produce concave surface during sawing and lack now, can reduce the end face run-out of saw blade.
Be achieved in that order of the present utility model on the both ends of the surface of the high-speed tool steel cast-cutting saw slice that is similar to circular saw blade for wood and grind certain tapering, its tapering grinds in the ratio of 1:500, make the tooth portion of saw blade thick, the middle part is thin, the place leaves a platform apart from the aperture, and at the place, secondary cutting face of sawtooth, with single face, two-sided or grind the inclined-plane every the left and right intersection of tooth.(do not draw two-sided in the accompanying drawing or every about tooth, intersect)
The utility model is because the tooth portion of tapering, saw blade that only need grind in the both ends of the surface of saw blade grinds certain inclined-plane, and it is simple in structure, and mode of operation is not had specific (special) requirements.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the schematic diagram of front view of the present utility model and cutaway view.
Describe architectural feature of the present utility model in detail below in conjunction with accompanying drawing.
The utility model is the cast-cutting saw slice of being made by a circular high-speed tool steel sheet, its saw blade comprises the saw body (2) and the sawtooth (3) thereof of platform (1) and band tapering, mill has inclined-plane (4) at the place, secondary cutting face of sawtooth (3), the angle of inclination on its inclined-plane (4) is 15 °-18 °, and the saw blade centre punch has an installing hole (5).The diameter of this saw blade is 25-32mm in the 200-350mm aperture.Saw blade hardness is HRc63 °-66 °, and thickness is 1.0-2.5mm, and it is simple in structure in full force and effect.
Claims (3)
1, a kind of by with tungsten being the refining high-speed tool steel cast-cutting saw slice that forms of metal material, it is characterized in that apart from installing hole (5) locate a platform (1) and the generation have the saw body (2) of tapering and circumference place thereof to cut sawtooth (3), there are inclined-plane (4), its inclined-plane (4) also can wear into two-sided or at the place, secondary cutting face of sawtooth (3) mill every the left and right intersection of tooth.
2, high-speed tool steel cast-cutting saw slice according to claim 1, it is characterized in that saw blade is to make with high-speed tool steel, hardness is HRc63-66, thickness is 1.0-2.5mm, the saw blade diameter is 200-350mm, the aperture is 25-32mm, and taper ratio is 1:500, and the angle of inclination of inclined-plane (4) is 15 °-18 °.
3, high-speed tool steel cast-cutting saw slice according to claim 1 and 2 is characterized in that said this saw blade, its hardness are HRc63-66, and the angle of inclination, inclined-plane is 16 °-17 °, and saw blade thickness is 1.2mm, and diameter is 250mm.
