Description

  The present invention relates to straight and arbitrary curve cutting by a circular saw (metal saw), and in particular, straight lines such as carbon fiber reinforced plastic laminated plates and duralumin plates, other synthetic resin plates, metal thin plates, stone materials, asphalt roads, etc., which are aircraft bodies. Further, the present invention relates to a straight and arbitrary curve cutting device using a novel circular saw for cutting an arbitrary curve.

  In recent years, for example, there has been an increase in demands for low fuel consumption in order to cope with an increase in international logistics by aircraft and to improve the environment for the earth, and weight reduction and improvement in fuel consumption of aircraft have been attempted. As a concrete measure, since fiber reinforced plastic composite products such as CFRP (carbon fiber reinforced plastic) are lightweight and have high strength and rigidity, structural members such as aircraft (main wing, tail wing, fuselage) Etc.). The straight and arbitrary curve cutting of the aircraft structural members is performed by a dedicated straight and arbitrary curve cutting machine, a hand tool (cutting tool using a circular saw), a curved blade cutter, and a water jet device. .

  As an example of the dedicated straight line and arbitrary curve cutting machine, a thin plate cutting machine is provided. The configuration is such that the holding member can be moved relative to the work table in any three-dimensional direction, and a rotary blade having a V-shaped cutting edge made of a super hard material is attached to the tip of the holding member. To do. The thin blade on the work table is cut by appropriately moving the rotary blade in the X-axis and Y-axis directions while rotating and driving the rotary blade at a high speed while moving the holding member down to a predetermined height. As a result, the small-diameter disk-shaped rotary blade is rotated relative to the plate material and moved in the X and Y axis directions to cut the plate material. For example, as in a conventional laser processing machine, the plate material is appropriately selected. The product having a shape can be easily cut out (for example, see Patent Document 1).

  The above-mentioned curved blade cutter is an improvement of a flat circular cutter (including a circular saw), and has a structure in which a mounting hole for a rotating shaft is provided at the center of a circular shape, and a cutting blade member or a saw tooth is provided on the outer periphery of the circular shape. It is a metal dish-shaped circular cutter equipped with a member, and the periphery of this outer periphery is formed of a conical dish bowl member, and several cut grooves are formed on the entire conical surface of the dish bowl member. The conical radial members are arranged at equal intervals, and the cutting blade members or sawtooth members provided on the outer peripheral edge of the counter ridge member are also arranged at equal intervals across the cut groove, and each has a circumferential arrangement in the conical shape. In addition, both the inner and outer side surfaces of the cone shape of the transplant blade member or the sawtooth member form the conical arc-shaped cutting blade. Thereby, first, the cutting blade to be rotated and cut can always maintain a suspended state with respect to the surface of the flat work material, and at the same time, during the rotary cutting and cutting with respect to the cutting edge width of the cutting and cutting blade, A constant clearance can be constantly maintained on both sides of the rotary blade. Next, as a rotary cutting curved blade that reasonably matches a circular arc of a required cutting circular shape of a flat work material, it is not subjected to excessive load such as galling or stagnation during rotary cutting (for example, (See Patent Document 2).

  The thin plate cutting machine moves the X- and Y-axis directions while rotating a small-diameter disk-shaped rotary blade relative to the plate material, and cuts the plate material easily. However, since the rotary blade has a V-shaped cutting edge, the cutting surface of the plate material has a V-shaped oblique shape, and correction processing is performed in which this cutting surface is a vertical surface. The problem of having to do is not solved.

  In addition, the above-mentioned curved blade cutter must be subjected to an excessive load such as squeezing and stagnation during the rotational cutting as a rotational cutting curved blade reasonably matching the large and small circular arcs necessary for cutting of a flat work material. However, since the in-cone angle of the curved blade cutter is fixed and fixed, it is limited to straight line and predetermined curve processing constrained by this in-cone angle. For this reason, there remains a problem that it is impossible to process a straight line and an arbitrary curve in which the processing straight line and the arbitrary curve change to the left and right, and the curvature radius arbitrarily changes continuously. That is, it cannot be applied to straight line and arbitrary curve machining that requires precise straight line and arbitrary curve machining with large workpieces, such as structural members (main wing, tail wing, fuselage, etc.) such as aircraft.

  In addition to the above, there are major problems that impair the machining of structural members such as aircraft (main wings, tail wings, fuselage, etc.). There is a need for development and practical application of curve cutting equipment. In addition, for other synthetic resin plates, metal thin plates, stones, asphalt roads, etc., use straight cutting as a basic technology, and after cutting, use straight or arbitrary curved cutting surfaces with tools such as cutting of luxury, cutting, cutting, etc. It is forced to cut straight and arbitrary curves.

  According to the first and second aspects of the present invention, the operation of the linear and arbitrary curve cutting device using the circular saw is achieved by balancing the pressing force of the elastic member and the pressing drive member on the left and right side surfaces of the circular saw in the direction of the rotational axis. Because the external force that changes the direction of the axis of rotation of the same axis makes it possible to control the bending of the axis of rotation, when the circular saw is in a straight stretched state that is evenly balanced with respect to the left and right sides, a carbon fiber reinforced plastic laminate or duralumin Circular saws can be linearly cut from plates, other synthetic resin plates, thin metal plates, stones, asphalt roads, and other plate materials and materials. Further, when the circular saw is in a bending posture curved with respect to the left side surface, it is possible to cut straight lines and arbitrary curves in the direction of the left side surface following the cross-sectional shape of the circular saw with respect to the plate material / material. When the circular saw is in a bending posture curved with respect to the right side surface, straight and arbitrary curve cutting in the right side surface direction following the cross-sectional shape of the circular saw with respect to the plate material / material can be performed.

  According to the third and fourth aspects of the present invention, since the circular saw is a spring steel or a resin material that can be bent, the bending amount and the straight extension of the circular saw to the left and right side surfaces are as follows. Since it is excellent in performance, arbitrary straight and arbitrary curve cutting and straight cutting in the left and right direction by a circular saw with respect to the plate material and the raw material are accurately performed.

  According to the fifth aspect of the present invention, the operation of the straight and arbitrary curve cutting device using the circular saw is such that the pressing drive member rolls and presses the roller provided at the tip of the pressing body that moves forward and backward to the side surface of the cone body that rotates integrally with the circular saw. Therefore, the circular saw can be deformed and controlled by pressing and rotating while the roller of the pressing drive member rolls with low resistance (low friction) on the side surface of the cone body that rotates integrally with the circular saw.

  According to the sixth and seventh aspects of the present invention, the operation of the linear and arbitrary curve cutting device by the circular saw is such that the lubricating coolant or gas supplied from the outside is radially radiated around the outer edge by self-pressure and centrifugal force. Since the jetting point is directly lubricated and cooled, the cutting resistance and cutting friction against the workpiece material are reduced, and the smooth cutting action with reduced chip heat generation and wear is maintained.

  According to the straight and arbitrary curve cutting device using the circular saw of the present invention, the circular saw can be bent in the direction of the rotation axis by the external force on the left and right sides in the direction of the rotation axis. In a straight stretch state that is evenly balanced, a circular saw can be cut straight. In the bending posture in which the circular saw is curved with respect to the left side surface, straight and arbitrary curve cutting in the left side direction following the cross-sectional shape of the circular saw with respect to the plate material / material can be performed. In the bending posture in which the circular saw is curved with respect to the right side surface, straight line and arbitrary curve cutting in the right side surface direction following the cross-sectional shape of the circular saw with respect to the plate material / material can be accurately performed.

  Since the above circular saw is made of spring steel or resin material that can be bent, it is excellent in the amount of bending and straight extension to the left and right sides of the circular saw, and arbitrary straight and arbitrary curve cutting and straight cutting by the circular saw with respect to the plate material Can be made even more accurate.

  The pressing drive member presses a roller that rolls at a low resistance provided at the tip of a push body that moves forward and backward against the side surface of the cone body that rotates integrally with the circular saw, so that the roller of the press drive member rotates integrally with the circular saw. The circular saw can be deformed and controlled by pressing and rotating while rolling on the side surface of the body with low resistance (low friction), and the heat generation and wear of this part can be drastically reduced.

  Lubricating coolant or gas supplied from the outside is lubricated and cooled directly to the outer periphery by self-pressure and centrifugal force against the above circular saw, so cutting resistance and cutting friction against workpiece materials can be reduced. Smooth cutting action with reduced chip heat generation and wear can be maintained.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  1st Embodiment of this invention is the linear and arbitrary curve cutting device 100 by the circular saw shown in FIGS. 1-3. A tool rotating shaft 2 connected to a main shaft 1 of a machine tool by a tapered portion 2A is rotatably supported by bearings B1 and B2 on left and right single frames 5A and 5B of a U-shaped frame 5. A circular saw 6 is fitted to the tool rotating shaft 2 and a center hole 6A serving as a flange is fitted. A pair of cone bodies 8 and 9 are fitted to the outer peripheral edges 6B and 6C of the circular saw 6 so that the protruding outer peripheral edges 8A and 9A are in contact with each other and rotate integrally with the tool rotating shaft 2. The circular saw is a flexible spring steel or a flexible resin material. The pair of cone bodies 8 and 9 are pressed against the outer peripheral edges 6B and 6C of the circular saw 6 so as to be able to advance and retreat in the axial direction from both sides.

  The configuration is such that a tool between one side 6B and one frame 5A at the outer peripheral edge of both sides of the circular saw 6 is formed with a coil-shaped elastic member 10 at the center of the back surface of one of the pair of cone bodies 8,9. The cone body 9 on the other side is adjusted and pressed by the pressing drive member 20 while being retracted and pressed on the rotating shaft 2. The pressing drive member 20 includes a pressing plate 21 fitted to the tool rotating shaft 2 between the outer peripheral edge 6C and the one frame 5B, and the pressing plate 21 is hydraulically or pneumatically forged or electric (a screw rod is driven by a motor). It is connected to an advancing / retreating drive unit (illustrated by a piston 22 and a cylinder 23) 24 driven by rotation. That is, the roller R attached to the tip of the piston 22 is pressed against the outer peripheral surface 21A of the pressing plate 21, and rolls on the outer peripheral surface 21A of the pressing plate 21 that rotates integrally with the rotation of the tool rotating shaft 2. To do. The roller R is rotatably supported with a low resistance, that is, a frictional resistance (rotatable with a low torque) with respect to the pin 22 </ b> A entangled at the tip of the piston 22. Thus, the roller R is configured to be rotatable with low resistance, that is, frictional resistance (rotatable with low torque) with respect to the circular saw 6 and cone body 9 rotating at high speed and the outer peripheral surface 21A of the pressing plate 21. . The circular saw 6, the pair of cone bodies 8 and 9, and the resilient member 10 also rotate integrally with the tool rotating shaft 2.

  Thus, between the circular saw 6 and the pair of cone bodies 8, 9, an elastic member 10 and an umbrella mechanism AK composed of the cone body 9 and the pressing drive member 20 are configured. In the advance / retreat drive unit 24, the piston 22 As shown in FIGS. 2 and 3, the push plate 21 is moved forward and backward by the pressing force F0 against the elastic force F of the elastic member 10 on the tool rotating shaft 2. That is, FIG. 1 shows a state where the elastic force F is equal to the pressing force F0 by controlling the pressing force F0 of the pressing drive member, and the pair of cone bodies 8 and 9 includes the circular saw 6 and the outer peripheral blade portion (the cutting edge for processing). Tip) 6D is set to the straight extension posture. Further, FIG. 2 shows a state where the elastic force F> the pressing force F0, and the pair of cone bodies are restricted to the right bending posture of the circular saw. FIG. 3 shows a state in which the elastic force F <the pressing force F0, and the pair of cone bodies regulate the circular saw to the left side bending posture.

  The straight and arbitrary curve cutting device 100 using the circular saw according to the first embodiment of the present invention is configured as described above and operates as shown in FIG. First, an umbrella mechanism AK is provided between the circular saw 6 and the cone bodies 8 and 9, and the advancing / retreating drive unit 24 controls the elastic force F = the pressing force F0 by controlling the pressing force F0 of the pressing drive member 20. In this state, the pair of cone bodies set the circular saw in a straight extending posture, and the circular saw 6 performs a straight cutting (straight processing) a on the plate material P. Further, in the advancing / retreating drive unit 24, when the elastic force F pressing force> F0 is controlled by the control of the pressing force F0 of the pressing drive member 20, the pair of cone bodies make the circular saw a right bending posture, The circular saw 6 performs a right straight line and arbitrary curve cutting (right straight line and arbitrary curve machining) b on the plate material P. Further, in the advance / retreat drive unit 24, when the elastic force F <the pressing force F0 is established by controlling the pressing force F0 of the pressing drive member 20, the pair of cone bodies set the circular saw to the left bending posture, The circular saw 6 performs left straight line and arbitrary curve cutting (left straight line and arbitrary curve machining) c on the plate material P.

  Furthermore, since the circular saw 6 is made of a spring steel or resin material that can be bent, the circular saw 6 is excellent in the amount of bending to the left and right side surfaces and the straight stretchability. Straight line and arbitrary curve cutting b, c and straight line cutting a are accurately performed. Further, the pressing drive member 20 presses the pressing plate 21 that presses the side surface of the cone body 9 that rotates integrally with the circular saw 6 with the roller R provided at the tip of the piston 22 that moves forward and backward. The circular saw is pushed and rotated while rolling with low resistance (low friction) on the side surface of the pressing plate 21 which presses the cone body 9 that rotates integrally with the circular saw, and the deformation of the circular saw is controlled.

According to the linear and arbitrary curve cutting device 100 using the circular saw according to the first embodiment of the present invention, the following effects can be obtained.
According to the straight and arbitrary curve cutting device 100 using the circular saw of the present invention, the circular saw 6 can be bent in the direction of the rotation axis by the external force on the left and right sides in the direction of the rotation axis. On the other hand, the circular saw 6 can be linearly cut in the straight stretched state evenly balanced. In the bending posture in which the circular saw is curved with respect to the left side surface, straight line and arbitrary curve cutting in the left side direction following the cross-sectional shape of the circular saw with respect to the plate material / material P can be performed. Further, in a bending posture in which the circular saw is curved with respect to the right side surface, straight and arbitrary curve cutting in the right side surface direction following the cross-sectional shape of the circular saw with respect to the plate material / material can be performed.

  Since the circular saw 6 is made of a spring steel or resin material that can be bent, it is excellent in the amount of bending to the left and right sides of the circular saw and straight stretchability, and arbitrary arbitrary curve cutting b, c in the left and right direction by the circular saw with respect to the plate material, The straight line cutting a can be made more accurate.

  The pressing drive member 20 presses the pressing plate 21 that presses the side surface of the cone body 9 that rotates integrally with the circular saw 6 with the roller R that rolls at a low resistance provided at the tip of the piston 22 that moves forward and backward. The circular saw can be deformed and controlled by rolling and rotating with a low resistance (low friction) to the pressing plate 21 that presses the side surface of the cone body whose roller rotates integrally with the circular saw, and the heat generation wear of this portion can be drastically reduced.

  The straight and arbitrary curve cutting device 100 using the circular saw 6 of the present invention is not limited to the configuration in the above embodiment, and the design can be freely changed within the gist of the present invention. As shown in FIG. 5, the linear and arbitrary curve cutting device 200 by the circular saw 60 of the 2nd Embodiment of this invention is shown. The structure consists of a tool rotating shaft 2 that is detachably connected to the main shaft 1, and a plurality of fan-like plates 60B on the outer periphery of a flange 60A that is fitted to the tool rotating shaft. It is mainly composed of a circular saw 60 provided with a CP and provided with adjacent gaps X swingable in the left-right direction and pivotally supported by a hinge H. In order to control the posture of the outer peripheral edge surfaces 60C and 60D that form the plurality of fan-shaped plates 60B of the circular saw 60, the tool rotation shaft is used to contact the projecting outer peripheral edges 8A and 9A of the pair of cone bodies 8 and 9 2, the outer peripheral edge 8 </ b> A of one of the pair of cone bodies is pressed by the elastic member 10 to one side 60 </ b> C on both outer peripheral edges of the circular saw 60 with the pressing force F, and the other side The cone body 9 is urgedly pressed by the pressing drive member 20 to one side 60D on both sides of the outer peripheral edge by the pressing force F0 having the same configuration as in the first embodiment. That is, by controlling the pressing force F0 by the pressing drive member, the pair of cone bodies 8, 9 causes the plurality of fan-shaped plates 60B of the circular saw 60 to extend straight (F = F0) and deflect toward the resilient member (F <F0) and an umbrella mechanism AK having a bending posture toward the pressing drive member side (F> F0) are provided. Other configurations are denoted by the same reference numerals and description thereof is omitted.

  The operation of the straight and arbitrary curve cutting device 200 by the circular saw 60 is as follows. As shown in FIG. 6, the circular saw 60 is moved between the elastic member 10 and the pressing drive member 20 on the left and right side surfaces in the direction of the rotation axis. Because the external force that changes the balance of the pressing force enables the lateral deflection of the rotating shaft to be controlled, when the circular saw is in a straight extension state (F = F0) that is evenly balanced with respect to the left and right side surfaces, A straight cut a of the circular saw 60 can be performed on a plate material / material P such as a carbon fiber reinforced plastic laminated plate, duralumin plate, other synthetic resin plates, metal thin plates, stone materials, asphalt roads, and the like. Further, when the circular saw 60 is in a bent posture (F <F0) curved with respect to the left side surface, straight line and arbitrary curve cutting in the left side direction following the cross-sectional shape of the circular saw 60 with respect to the plate material / material P is performed. c becomes possible. When the circular saw is in a bent posture (F> F0) with respect to the right side surface, the straight line and arbitrary curve cutting b in the right side direction following the cross-sectional shape of the circular saw with respect to the plate material / material P is It becomes possible.

  According to the straight and arbitrary curve cutting device 200 using the circular saw of the present invention, the outer periphery of the circular saw 60 becomes a plurality of fan-shaped fan plates 60B in the rotational axis direction by the external force on the left and right side surfaces that are in the rotational axis direction. Since both surfaces 60C and 60D can be bent to the left and right, in a straight extension state where the circular saw is evenly balanced with respect to the left and right side surfaces, the circular saw can be linearly cut a. In the bending posture in which the circular saw is curved with respect to the left side surface, a straight line and an arbitrary curve cutting c in the left side direction following the cross-sectional shape of the circular saw with respect to the plate material / material P can be performed. Further, in a bending posture in which the circular saw is curved with respect to the right side surface, straight line and arbitrary curve cutting b in the right side surface following the cross-sectional shape of the circular saw with respect to the plate material / material can be performed. In addition, the circular saw is provided with a flange 60A and a plurality of fan-shaped plates 60B and outer peripheral surfaces 60C and 60D, and a peripheral edge X that is provided with a cutting edge tip C on its outer periphery and can be swung left and right. Since it is pivotally supported, the bending posture is greatly curved, and it is good at cutting large curved straight lines and arbitrary curves with small curvature radii.

  Other functions and effects are the same as those of the straight and arbitrary curve cutting device 100 using the circular saw according to the first embodiment.

  In the linear and arbitrary curve cutting apparatus 100 using the circular saw, as shown in FIG. 7, the lubrication cooling supplied from the nozzle N installed outside is provided on the outer peripheral surfaces 6B and 6C of one disk of the circular saw 6. Liquid E or gas K is lubricated and cooled directly to the processing point K0. Alternatively, the lubricating coolant E or gas K is radially ejected from the nozzle N1 protruding from the center hole 6A serving as a flange through the through hole h penetrating the tool rotating shaft 2 to the outer peripheral surfaces 6B and 6C by the self-pressure and centrifugal force. Then, the machining point K0 is directly lubricated and cooled.

  Further, in the linear and arbitrary curve cutting device 200 using the circular saw, as shown in FIG. 8, the lubrication cooling supplied from the nozzle N installed outside is provided in the adjacent gaps X of the plurality of fan-shaped plates 60B of the circular saw 60. Liquid E or gas K is lubricated and cooled directly to the processing point K0. Alternatively, the lubricating coolant E or gas K is radially ejected from the nozzle N1 protruding from the center hole 6A serving as a flange through the through hole h penetrating the tool rotating shaft 2 to the outer peripheral surfaces 6B and 6C by the self-pressure and centrifugal force. Then, the machining point K0 is directly lubricated and cooled.

  Therefore, is the lubricating cooling liquid E or the gas K supplied to the machining point K0 from the outside to the circular saws 6 and 60 and directly lubricated and cooled? In addition, since the lubricating coolant E or gas K is radially jetted around the outer edge by self-pressure and centrifugal force, the machining point K0 is lubricated and cooled directly, so that the cutting resistance and cutting friction against the workpiece P can be reduced, and the cutting edge for machining Smooth cutting action with reduced chip heat generation and wear can be maintained.

  The present invention has been described in the embodiments targeting the workpieces such as carbon fiber reinforced plastic laminates, duralumin plates, other synthetic resin plates, metal sheets, stones, asphalt roads, etc. However, it can be applied to plate-like / material workpieces in various product devices.
