Abstract
The utility model provides a multifunctional saw blade which can be arranged and clamped on a portable hand saw handle. The multifunctional saw blade not only can be used as a saw, but also can be used as a knife, has the functions of sawing, sawing, peeling, cutting, carving, scraping, etc., and can be suitable for indoor and outdoor decoration, mechanical and electric appliance repair and daily life. The saw blade not only is provided with saw teeth (1), a cusp (2) and a cutting edge (3), but also is provided with a score (4). When the cutting edge of the cusp is dull, can be used when a certain mode to apply bending moment, the cusp can be broken off along the score by the bending moment applied by using a certain mode. Thus the new sharp cutting edge of the cusp is reproduced.
Description
The present invention relates to a kind of improved multi-functional saw blade, one side of this saw blade is a sawtooth, be used for the sawing material, opposite side has wedge angle and puts the first edge on a knife or a pair of scissors, be used for cutting, cut, carve, cutting to material, the indentation of some parallel oblique is particularly arranged on it has the saw face of cutting edge, and these indentations have guaranteed the repeatedly renewal of this cutlery wedge angle cutting edge, can give full play to it and cut, carve function when the cutter time spent.
The general side of existing saw blade is a sawtooth, and opposite side does not utilize; There are a kind of both sides that the saw blade of tooth is arranged, also only have the sawing function.Existing decorative engineering wallpaper cutter, though the function of cutter is arranged, and its wedge angle can repeat to upgrade, and do not possess the sawing function, and task of the present invention is exactly: provide a kind of and can work as saw usefulness, can work as the saw blade that cutter usefulness and wedge angle cutting edge can repeat to upgrade again.
Task of the present invention is finished as follows: a kind of saw blade at first is provided, and this saw blade one side is a sawtooth, its opposite side dorsad the sawtooth point towards an end, cut out the wedge angle of a suitable angle, begin from pointed tip, grinding goes out the sharp cutting edge of light.In the plane of cutting edge place length, processing with the cutting edge wedge angle does not have some parallel trickle indentations of cutting edge on one side.The spacing distance of these indentations equates, its degree of depth, width, the intensity when neither the influence row is executed the sawing function can reach again when the wedge angle cutting edge rust of this saw blade, with the bending moment of certain mode it is fractureed along indentation and come off, thereby repeatedly pay attention to the purpose of sharp keen wedge angle cutting edge.The number of times that the wedge angle cutting edge reappears is corresponding with the bar number of indentation.
Indentation can be with special equipment delineation processing on the stock of undressed profile of tooth, and slitting processes sawtooth and wedge angle then, and corase grind cutting edge, finish grind cutting edge after the heat treatment again, or after heat treatment disposable grinding cutting edge (note the cooling of cutting edge, still will keep former heat treated hardness after the grinding).Technology for Heating Processing should guarantee the grazing of the suitable bending strength of saw blade, hardness and outward appearance.This saw blade generally adopts carbon tool steel, also can adopt high-speed tool steel, and heat treatment hardness is HRC55-65.
This saw blade mainly is applicable to portable multi-function handsaw (declaring utility model patent on December 23rd, 93 by the inventor).With its clamping on this handsaw, can the sawing metal, plastics and wood materials, also can cut, cut, cut, carve paper, artificial leather, flexible material etc.The clamping position of saw blade and direction, the use length of saw blade sawtooth and blade can arbitrarily be adjusted, to adapt to different operating mode needs.This handsaw is applicable to family and indoor and outdoor decoration, in the repairing and daily life of machinery, electrical installation.
In addition,, put the first edge on a knife or a pair of scissors in a manner described, and adopt portable multi-function handsaw clamping, can make the former reciprocating saw blade of can only machine using, also can be used for manually, and increase the function of its cutter the electric reciprocating saw blade.Existing telescopic decorative engineering wallpaper cutter is if adopt above-mentioned form, with offside tooth punching and suitable lengthening, can increase the function of its sawing, so not only can widen its original purposes, make things convenient for our work life, and can save a large amount of instrument steel.
Below in conjunction with accompanying drawing this invention is described further:
With reference to Fig. 1, a long 90-290 millimeter, wide 10-18 millimeter, the saw blade of thick 0.5-1.0 millimeter, one side are sawtooth (1), and tooth pitch is the 1.4-1.8 millimeter, sawtooth point dorsad towards an end do not have sawtooth one side, it is 45 °-70 ° wedge angle (2) that one angle is arranged, and the cutting edge of a knife or a sword that from the top of wedge angle (2) effective length to be arranged be the 50-120 millimeter gets cutting edge (3), and the cutting edge wedge angle is 18 °-25 °.On the plane of cutting edge place length, have some with the end edge of the no cutting edge of wedge angle (2) along indentation (4) parallel and that spacing distance equates, its spacing is the width of 0.5-1.0 times of saw blade.Along reaching blade, its width, the degree of depth and spacing be by the cutter and the processing technology assurance that be indentation (4) design from sawtooth bottom for indentation (4), and adapt with the thickness and the width of saw blade.
Claims (4)
1, an a kind of side has the multi-functional saw blade of sawtooth (1), it is characterized in that: an end of the opposite side of this saw blade has wedge angle (2), and the sharp cutting edge (3) of a light and the trickle indentation (4) parallel to each other of some inclinations are arranged from wedge angle (2) top.
2, saw blade according to claim 1 is characterized in that: indentation (4) is parallel with one side of the no cutting edge of wedge angle (2), and is distributed in the saw face of cutting edge (3) place length.
3, according to the described saw blade of claim 2, it is characterized in that: the spacing distance of indentation equates that its spacing distance is in saw blade width 0.5-1.0 scope doubly.
4, saw blade according to claim 3, it is characterized in that: the length of this saw blade is the 90-290 millimeter, wide 10-18 millimeter, thick 0.5-1.0 millimeter, tooth pitch is the 1.4-1.8 millimeter, wedge angle (2) is 45 °-70 °, and the angle of cutting edge (3) is 18 °-25 °, and the effective length of cutting edge (3) is the 50-120 millimeter.
