Abstract
The utility model provides an omnidirectional fret saw blade. Saw teeth-shaped by punching and chiseling are arranged on the cylinder face of a steel wire in the omnidirectional way. Both ends of the saw blade are connected with hanging rings used for stretching and positioning. The saw blade can do omnidirectional sawing and cutting, while workpieces just need to do orthogonal motion in both the vertical direction and the horizontal direction without rotation to complete sawing and cutting of any plane curves. Thus the condition of realizing automatic to realize automatic curve sawing and cutting can be provided. The saw blade has high sawing and cutting precision, can increase the work efficiency in a double way, and is suitable for curve sawing and cutting of materials such as wood, plastics, rubber, organic glass, etc.
Description
The utility model relates to the woodworking machinery technical field, particularly a kind of comprehensive wire saw blade in order to sawing curve workpiece.
In the prior art, the wire saw blade in order to sawing curve workpiece is towards cutting a hole the sawtooth that is shaped and constituting in the upper edge, a side face of cylinder of round wire axially-aligned.This thread saw blade can only be made folk prescription to sawing behind tension location on the saw bow, if the sawing curve, the operator is turning of work piece or saw blade constantly, to adjust the sawing direction.With this saw blade sawing curve, time-consuming, precision is low, and workpiece interchangeability is poor, particularly uses this saw blade to be difficult to realize the automatic and mechanical sawing.
The purpose of this utility model is to overcome the deficiency of above-mentioned wire saw blade, the folk prescription position of the sawtooth on the former thread saw blade from the circumference is arranged change comprehensive arrangement into, and a kind of wire saw blade that can comprehensive sawing is provided.
Comprehensive wire saw blade described in the utility model, the sawtooth that is shaped by round wire, at steel wire upper punch cutter, be positioned at the suspension ring that the saw blade two ends are used to strain the location and form, on the steel wire face of cylinder, along its circumference and axially all there is sawtooth to arrange the axis projection of sawtooth on the steel wire cross-sectional circumferential on the unit length saw blade greater than 4 teeth, the axially spaced-apart between any two adjacent sawtooth is the 1-5 millimeter.
The sawtooth of above-mentioned wire saw blade can be arranged by the helix form on the steel wire face of cylinder.
In order to make the workpiece reverse side keep bright and clean, do not stay burr, can on one section saw blade of 1-5 centimeter length, sawtooth be made progress towards cutting a hole into crown at the downward saw blade latter end of sawtooth crown.
Advantage of the present utility model is: because sawtooth comprehensive arrangement on the saw blade circumference, so can be used as comprehensive sawing, behind the saw blade tension location, need not turning of work piece and saw blade, as long as with the plane of workpiece edge perpendicular to saw blade, do the orthogonal motion of both direction in length and breadth, can finish the sawing of any plane curve, this has just created condition for the sawing of realization automatic and mechanical curve.Simultaneously, sawing precision height can significantly improve work efficiency, and the uniformity of workpiece and interchangeability have also just had may.This thread saw blade is suitable for the usefulness that materials such as timber, plastics, rubber, lucite are done the curve cutting.
Further specify architectural feature of the present utility model below in conjunction with accompanying drawing embodiment.
Fig. 1 is comprehensive wire saw blade structure schematic diagram;
Fig. 2 is the thread saw blade partial enlarged drawing;
Fig. 3 is the perspective view of sawtooth on the saw blade cross-sectional circumferential;
Fig. 4 is the arrangement expanded view of sawtooth on the steel wire face of cylinder.
Fig. 1-Fig. 4 is described to be an embodiment of the present utility model.It is to be that the steel wire (1) of 0.5-2.5 millimeter is made with diameter, and the suspension ring (3) that respectively have steel wire to be hinged at the saw blade two ends are attached thereto, in order to the stretch-draw location of saw blade.On the face of cylinder of steel wire (1), reach sawtooth (2) arrangement that axially all has through being shaped along its circumference towards cutter.The sawtooth of present embodiment (2) is to arrange on the face of cylinder with helix (among the figure shown in the dotted line) form, axis projection on steel wire (1) cross-sectional circumferential is by a, c, e, g, b, d, f, the order of a is arranged, every two weeks of rotation of helix, sawtooth (2) is arranged as one-period, (the g shown in Fig. 2 for example if adjacent two sawtooth, b two teeth) axially spaced-apart M is 1 millimeter, the unit length that the sawtooth of side one-period is arranged on saw blade is 7 millimeters, so the axis projection that the sawtooth on the present embodiment unit length T is arranged on the steel wire cross-sectional circumferential is 7 teeth.
In order to improve the fineness of sawing, make the workpiece reverse side not stay burr, at the saw blade latter end that the sawtooth crown is arranged downwards, it is the saw blade of 1-5 centimeter length that L can be arranged, its sawtooth crown is upwards arranged, in order to fall to remove workpiece reverse side burr.
Sawtooth (2) also can other form be arranged on steel wire (1) face of cylinder, as long as the axis projection of sawtooth on cross-sectional circumferential on guarantor unit's length saw blade is greater than 4 teeth, keep suitable axially spaced-apart between any adjacent sawtooth, all do not depart from matter of the present utility model.
Claims (3)
1, a kind of comprehensive wire saw blade, being connected the suspension ring that are used for saw blade tension location by round wire, at the sawtooth of steel wire upper punch cutter shaping, with the steel wire two ends forms, it is characterized in that: on the steel wire face of cylinder, along its circumference and axially all there is sawtooth to arrange, sawtooth on the unit length saw blade is arranged in axis projection on the steel wire cross-sectional circumferential greater than 4 teeth, and the axially spaced-apart of any two adjacent sawtooth is the 1-5 millimeter.
2, wire saw blade according to claim 1 is characterized in that: sawtooth is pressed the helix form and is arranged on the steel wire face of cylinder.
3, wire saw blade according to claim 1 and 2 is characterized in that: in the saw blade latter end that the sawtooth crown is arranged downwards, can have the sawtooth crown on the saw blade of 1-5 centimeter length upwards to arrange.
