Description
Technical field
The utility model relates to the scroll saw field, especially a kind of scroll saw for cutting timber.
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 has cut object just to have cutting ability over against the direction motion 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 bowlder of processing on the long plank of a slice 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 linkage function more than three axles to the control of lathe.Lathe has been proposed very high requirement.Equipment cost is high, is difficult for penetration and promotion and uses.Therefore, carrying out the mode that curvilinear cut can only adopt carving to mill on this long sheet material completes.
In the prior art, be a kind of omnidirectional fret saw of 94211675.5 as the patent No., this saw blade has sawtooth to arrange on the steel wire face of cylinder, and sawtooth is arranged in circle orientation on the saw blade circumference, 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 to fracture.It is very difficult that but the saw blade of this structure is made, not only cost is high to make this saw blade, production efficiency is low, saw blade needs length customized in making, and in use, the sawtooth on saw blade easily damages, and can't change or repair, especially easily local damage if change cause use cost very high, is not changed the quality that affects processing parts.Due to when cutting part contact with steel wire on saw blade, easily damage steel wire, can't repair after damage, this saw blade is very unpractical in actual applications, is unfavorable for being widely used.Particularly the use on the 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 in cutting during 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, too intensive if sawtooth distributes, wood chip easily stops up sawtooth, affects cutting effect; If the sawtooth distribute spacing is too large, affect cutting force.Need to change saw blade when therefore cutting unlike material timber, therefore standby multiple saw blade, cause cost high.
The utility model content
The utility model 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 utility model solves the technical scheme that its technical problem adopts: this scroll saw for cutting timber, comprise steel wire, and the 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.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, and requiredly according to reality going here and there the saw cover of Len req on steel wire, and the length of saw blade is easily regulated, and after saw is enclosed within cutting and is worn, only needs the saw cover that damages is changed, and 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 steel wire between further perfect, 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 steel wire form can the 360 comprehensive cuttings of degree saw blade, and the saw of this spline structure cover makes easily, cost is low, the saw cover is not easy damage.
The surrounding of taper surface is provided with sawtooth.Set up sawtooth on taper surface, cutting effect is better like this.
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 360 comprehensive cuttings of degree like this.
One end of steel wire is the stiff end that is fixed on frame, and the other end penetrates end for the saw cover.Stiff end can be fixed on sawing machine easily, also plays to prevent that the saw cover from skidding off outside steel wire.
The effect that the utility model is useful is: the saw blade in the utility model has comprehensive cutting power, simple in structure, reasonable in design, cost of manufacture is low, and be convenient to keep in repair and regulate the length of saw blade, can also regulate the spacing size of sawtooth on saw blade, make wood chip be not easy to be blocked on saw blade, strengthen the cutting effect of saw blade.Provide a kind of effective scroll saw in particular for the numerical control curve cutting.

Description of reference numerals: steel wire 1, stiff end 1-1 penetrates end 1-2, saw cover 2, through hole 2-1, cut surface 2-2, sawtooth 2-21, spacer 3.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment one: with reference to accompanying drawing 1, this scroll saw for cutting timber comprises steel wire 1, and steel wire 1 overcoat has the saw cover 2 of one group of cylinder-like structure, and each adjacent saw cover 2 closely connects, and the outer surface of saw cover 2 is provided with the cut surface 2-2 for cutting.The centre of saw cover 2 is provided with the through hole 2-1 that is enclosed within on steel wire 1, and saw cover 2 is wrapped in outside steel wire 1 like this, and steel wire 1 can not be worn, and saw cover 2 is a plurality of monomer structures, also is convenient to change single or multiple saw covers 2 in case damage, and the length of saw blade is also easily regulated.
Embodiment two: with reference to accompanying drawing 2, cut surface 2-2 is for becoming gradually large taper surface from top to bottom.This structure is comparatively simple, and also very firm, the cut surface on the product that cuts out is smooth.
