Description
Technical field
The present invention relates to a kind of scroll saw field for cutting timber, especially a kind of for cutting timber scroll saw and its jigsaw is installed.
Background technology
Present scroll saw has two kinds.A kind of is to utilize steel wire to dig out sawtooth in steel wire one side, and another kind is very narrow saw blade.The cutting mode of these two kinds of saws only is cut object and just has cutting ability over against the motion of the direction of cutting edge.Therefore, when doing the curve cutting.Dual mode is arranged: a kind of is that the relative scroll saw of workpiece moves along a curved path, and requires workpiece to have this moment and rotatablely moves.As processing a bowlder at the long plank of a leaf length, length direction has just limited rotatablely moving of workpiece, does not process a full circle.Another kind is scroll saw moving along processed curve.Same plank length also can limit rotatablely moving of saw frame.Therefore, if adopt digital control processing, must reach interlock function more than three to the control of lathe.Lathe has been proposed very high requirement.The equipment cost height is difficult for penetration and promotion and uses.Therefore, carrying out the mode that curvilinear cut can only adopt carving to mill at this long sheet material finishes.
In the prior art, be 94211675.5 a kind of comprehensive wire saw blade as the patent No., this saw blade has sawtooth to arrange on the steel wire face of cylinder, and sawtooth is arranging in saw blade circumference circle orientation, so 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 big internal stress in it, in use very easily causes to fracture.It is very difficult that but the saw blade of this structure is made, make not only cost height of this saw blade, production efficiency is low, saw blade needs length customized in making, and in use, the sawtooth on the saw blade damages easily, and can't change or repair, local damage especially easily if change then cause use cost very high, is not changed the quality that then influences processing parts.Since when cutting part contact with steel wire on the saw blade, damage steel wire easily, can't repair after the damage, this saw blade is very unpractical in actual applications, is unfavorable for being extensive use of.Particularly the use on numerical control curvilinear cut machine proposes higher requirement to the durability of scroll saw.
And saw blade can produce a large amount of wood chips in cutting during timber, and wood chip is easy to carve on sawtooth, influences the cutting effect of sawtooth.Therefore according to the timber of unlike material, adopt the saw blade of different densities sawtooth, too intensive if sawtooth distributes, then wood chip stops up sawtooth easily, influences cutting effect; If the sawtooth distribute spacing is too big, then influence cutting force.Need change saw blade when therefore cutting unlike material timber, therefore standby multiple saw blade causes the cost height.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of scroll saw for cutting timber is provided, and its structural design advantages of simple can realize comprehensive cutting, and 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, comprise steel wire, and steel wire is with the saw cover of one group of tubular structure outward, and the outer surface of saw cover is provided with the cut surface for cutting.Saw cover is wrapped in the outside of steel wire like this, and each adjacent saw cover closely connects, and does not contact steel wire when cutting, can not produce wearing and tearing to steel wire, thus saw blade do not allow easily broken, long service life; And the length of steel wire is easy to shear, according to reality required on steel wire is gone here and there the saw cover of Len req, the length of saw blade is regulated easily, saw is enclosed within after cutting is worn, and only needs the saw cover that damages is changed, it is convenient to change, and replacement cost is low like this.
In order to be provided with the spacer that is enclosed within on the steel wire between further perfect, the adjacent saw cover.According to the required length that spacer is set, the spacing size of regulating between the 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.Saw cover is frustum cone structure like this, and the outer surface of round platform is the cut surface of pyramidal structure, like this cover of the saw on the steel wire form can the comprehensive cutting of 360 degree saw blade, and the saw of this spline structure cover makes easily, cost is low, the saw cover is not easy damage.
Be provided with sawtooth around the taper surface.Set up sawtooth at taper surface, the such cutting effect of sawtooth is better.
Cut surface is cylindrical surface structure, and the cut surface periphery is provided with a circle sawtooth.Sawtooth is distributed in saw cover outer surface one circle, and the saw cover plays the effect of the comprehensive cutting of 360 degree like this.
One end of steel wire is the stiff end that is fixed on the frame, and the other end penetrates end for the saw cover.Stiff end can be fixed on the sawing machine easily, also plays to prevent that the saw cover from skidding off outside the steel wire.
The above-mentioned jigsaw for the scroll saw that cuts timber of this employing, comprise respectively fixedly steel wire upper holder and the lower fixed frame at two ends up and down, upper holder and lower fixed frame all are fixed on the sliding seat, sliding seat is pressed on frame by slide rail, and be provided with in frame and promote the push rod that sliding seat reciprocatingly slides, push rod is connected on the motor-driven disk.Screw hole location on the disk is according to the reciprocal distance up and down of the conveniently adjusted disk length adjustment of the thickness of rapidoprint saw frame.Reciprocating frequency is regulated by the speed of motor.
The outer end of upper holder is threaded and regulates the rise pole of saw cover elasticity, and wherein steel wire passes the rise pole, and the lower end roof pressure that raises pole puts at saw; The outer end of lower fixed frame is threaded and regulates the lower dolly bar of saw cover elasticity, and wherein steel wire passes lower dolly bar, and the lower end roof pressure of lower dolly bar puts at saw; Lower dolly bar passes the lower fixed frame lower end, and is connected with the steel wire regulating part at the lower end of lower dolly bar screw thread, and wherein the lower end of steel wire is fixed on the steel wire regulating part.
Upper holder is fixed in this regulating tank by securing member, and at sliding seat feed screw nut's cover of regulating the upper holder upper-lower position is installed.
Frame is provided with for the clamp mechanism that clamps timber, clamp mechanism comprises supporting seat and the down-pressed pole that is fixed on the frame, supporting seat is provided with the ball that supports timber, depression bar is established in the outer end of down-pressed pole, the centre of depression bar is rotatably connected on the outer end of down-pressed pole, the outer end of depression bar is provided with the pressure head that compresses timber, and the inner of depression bar is provided with the handle that makes the perk of depression bar outer end, and down-pressed pole is provided with the spring that withstands on the handle bottom surface.
The effect that the present invention is useful is: the saw blade among the present invention has comprehensive cutting power, simple in structure, reasonable in design, cost of manufacture is low, and is convenient to keep in repair and regulate the length of saw blade, can also regulate the spacing size of sawtooth on the saw blade, make wood chip be not easy to be blocked on the saw blade, strengthen the cutting effect of saw blade, and at this saw blade appropriate design jigsaw, the saw blade two ends are fixed on the lathe effect that the control saw blade moves up and down and realize to cut timber.Provide a kind of effective scroll saw in particular for the numerical control curvilinear cut.
