Description
Technical field
The present invention relates to a kind of jigsaw field for cutting timber, especially a kind of jigsaw for installing timber cutting scroll saw.
Background technology
Current scroll saw has two kinds.One utilizes steel wire to dig out sawtooth in steel wire side, and another kind is very narrow saw blade.The cutting mode of these two kinds saws, only has cut object just just to have cutting ability to the direction motion of cutting edge.Therefore, when making curvilinear cut.There are two kinds of modes: one is that the relative scroll saw of workpiece moves along a curved path, and now requires that workpiece has rotary motion.As processed a bowlder on the plank that a leaf length is longer, length direction just limits the rotary motion of workpiece, does not process a full circle.Another kind is scroll saw moving along processed curve.Same plank length also can limit the rotary motion of saw frame.Therefore, if digital control processing will be adopted, the linkage function of more than three axles must be reached to the control of lathe.Very high requirement is proposed to lathe.Equipment cost is high, not easily penetration and promotion application.Therefore, this longer sheet material carrying out curvilinear cut can only adopt the mode of carving milling.
In the prior art, if the patent No. is a kind of omnidirectional fret saw of 94211675.5, this saw blade has sawtooth to arrange on the steel wire face of cylinder, and sawtooth is circumferentially enclosing orientation arrangement at saw blade, therefore can be used for comprehensive cutting.The sawtooth of this saw adopts chisel to dig out on the steel wire face of cylinder.Therefore, there is very large internal stress in it, in use very easily causes and fracture.But the saw blade of this structure makes very difficult, not only cost is high to make this saw blade, production efficiency is low, saw blade need need length customized in making, and in use, the sawtooth on saw blade easily damages, and cannot change or repair, especially easily local damage, if changed, causes use cost very high, does not change, affect the quality of processing parts.Because when cutting, part contacts with the steel wire on saw blade, easily damage steel wire, cannot repair after damage, this saw blade is very unpractical in actual applications, is unfavorable for widely using.Use particularly on numerical control curve cutting machine proposes higher requirement to the durability of scroll saw.
And saw blade can produce a large amount of wood chips when cutting timber, and wood chip is easy to carve on sawtooth, affects the cutting effect of sawtooth.Therefore according to the timber of unlike material, adopt the saw blade of different densities sawtooth, if sawtooth distribution is too intensive, then wood chip easily blocks sawtooth, affects cutting effect; If sawtooth distribute spacing is too large, then affect cutting force.Need to change saw blade when therefore cutting unlike material timber, therefore multiple saw blade for subsequent use, causes cost high.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and provide a kind of jigsaw for installing timber cutting scroll saw, its structural design advantages of simple, can realize comprehensive cutting, not only cost of manufacture is low, and can keep in repair, and use cost is low.
The present invention solves the technical scheme that its technical problem adopts: this scroll saw for cutting timber, comprises steel wire, and steel wire overcoat has the saw cover of one group of tubular structure, and the outer surface of saw cover is provided with the cut surface for cutting.Such saw cover is wrapped in the outside of steel wire, each adjacent saw cover compact siro spinning technology, and do not contact steel wire when cutting, can not produce wearing and tearing to steel wire, therefore saw blade is not allowed easily broken, long service life; And the length of steel wire is easy to shear, according to actual required saw cover of going here and there Len req on steel wire, the length of saw blade easily regulates, and saw is enclosed within after cutting is worn, and only need change the saw cover damaged, it is convenient to change, and such replacement cost is low.
In order to be provided with the spacer be enclosed within steel wire between perfect further, adjacent saw cover.According to the required length arranging spacer, the spacing size regulated between saw cover is played in the effect of spacer, can reduce wood chip incrustation on saw blade, strengthens the cutting effect of saw blade.
Cut surface is taper surface.Such saw cover is frustum cone structure, and the outer surface of round platform is the cut surface of pyramidal structure, and the saw cover on such steel wire is formed can the saw blade of 360 degree comprehensive cuttings, and the saw cover of this spline structure makes easily, and cost is low, and saw cover is not easy damage.
The surrounding of taper surface is provided with sawtooth.Taper surface sets up sawtooth, and the such cutting effect of sawtooth is better.
Cut surface is cylindrical surface structure, and cut surface periphery is provided with a circle sawtooth.Sawtooth is distributed in saw cover outer surface one circle, and saw cover plays the effect of 360 degree of comprehensive cuttings like this.
One end of steel wire is the stiff end be fixed in frame, and the other end penetrates end for sawing cover.Stiff end can be fixed on sawing machine easily, also plays and prevents saw cover from skidding off outside steel wire.
The jigsaw of the above-mentioned scroll saw for cutting timber of this employing, comprise the upper holder and lower fixed frame of fixing the upper and lower two ends of steel wire respectively, upper holder and lower fixed frame are all fixed on sliding seat, sliding seat is pressed in frame by slide rail, and in frame, being provided with the push rod promoting sliding seat and reciprocatingly slide, push rod is connected on motor-driven disk.Screw hole location on disk is according to the back and forth upper and lower distance of the thickness of rapidoprint conveniently adjusted disk length adjustment saw frame.Reciprocating frequency is regulated by the speed of motor.
The outer end of upper holder is threaded and regulates the upper adjusting rod of saw cover elasticity, and wherein steel wire is through upper adjusting rod, and the top, lower end of upper adjusting rod is pressed in saw and puts; The outer end of lower fixed frame is threaded and regulates the lower dolly bar of saw cover elasticity, and wherein steel wire is through lower dolly bar, and the top, upper end of lower dolly bar is pressed in saw and puts; Lower dolly bar is through lower fixed frame lower end, and the steel wire regulating part that has been threaded in the lower end of lower dolly bar, wherein the lower end of steel wire is fixed on steel wire regulating part.
Upper holder is fixed in this regulating tank by securing member, and on sliding seat, install the feed screw nut's cover regulating upper holder upper-lower position.
Frame is provided with the clamp system for clamping timber, clamp system comprises and is fixed on supporting seat in frame and down-pressed pole, supporting seat is provided with the ball supporting timber, depression bar is established in the outer end of down-pressed pole, the central rotational of depression bar is connected to the outer end of down-pressed pole, the outer end of depression bar is provided with the pressure head compressing timber, and the inner of depression bar is provided with the handle that depression bar outer end is tilted, and down-pressed pole is provided with the spring withstanding on handle bottom surface.
The effect that the present invention is useful is: the saw blade in the present invention has comprehensive cutting power, structure is simple, reasonable in design, cost of manufacture is low, and is convenient to the length keeping in repair and regulate saw blade, the spacing size of sawtooth on saw blade can also be regulated, make wood chip be not easy to be blocked on saw blade, strengthen the cutting effect of saw blade, and for this saw blade appropriate design jigsaw, saw blade two ends are fixed on lathe, control saw blade and move up and down and the effect realizing cutting timber.Especially numerical control curve cutting provides a kind of effective scroll saw.
