いる。(Example) Examples of the present invention will be described in detail below with reference to FIGS. 3 to 5. As shown in the figure, the curve cutting device of this embodiment is
It is equipped with a plate feed roll device @ 8 for feeding the plate material 5 to be cut in the direction shown by the arrow 7, and a cutting blade drive device 9 installed in a direction transverse to the plate material 5 to be cut. The cutting blade drive device 9 includes a holding frame 10 through which the plate material 5 to be cut passes.
A pair of drive screws 11.12 are rotatably supported inside the drive screws 11.12 in parallel to the upper and lower inner surfaces thereof, and these drive screws 11.12 are connected to the synchronization gear mechanism 13.
The control motor 14 rotates the motor synchronously through the control motor 14. Blade holders 15 and 16 are screwed into the upper and lower driving screws 11 and 12, respectively, and are guided by the holding frame 10 and driven in a direction across the plate material 5 to be cut by the synchronous rotation of these driving screws 11 and 12. It is now possible to do so. A convex cutting blade roller 19 and a concave cutting blade roller 20 are rotatably supported on each blade holding table 15, 16 via spherical alignment bearings 17, 18, respectively. The convex cutting edge roller 19 has a cutting edge portion 19B protruding from the center of the roll surface 19A along the circumference. The concave cutting edge roller 20 has a shape in which a groove 20B into which the cutting edge portion 19B fits is provided along the circumference at the center of the roll surface 2OA.

的に描かれるあらゆる軌跡の切断が可能である。Such a curve cutting device controls the number of rotations of the rollers of the sheet feed roll device 8, that is, the traveling speed of the sheet material 5 to be cut, and the transfer speed of the double-edged rollers 19.20 in the direction of movement shown by the arrow 7.21. Cutting can be performed with a cutting line tracing a locus in the direction of the composite vector of the velocity vectors. For example, a simple right-angle cut can be performed by stopping the sheet feed roll device 8, operating only the cutting blade drive device 9, and moving both cutting blade rollers 19, 20 in the direction of the arrow 21. Also, the advancing speed of the plate material 5 to be cut and the double cutting edge roller 1
When the advancing speed of 9.20 is set in a 1:1 ratio by the controller 24, an inclined cutting of tan θ=1, that is, 45° can be performed. Controller 2 controls the moving speed of both cutting edge rollers 19 and 20.
4, it is possible to cut any trajectory drawn two-dimensionally by controlling the reciprocation.

The cutting edge part 19 is held between the roll surfaces 19A and 2OA of the
Due to the action of B and the groove 20B, double-edged cutting is performed at both edge portions of the cutting edge portion 19B while producing a cutting layer with the width of the cutting edge portion 19B.

2 seconds, but in the case of the curve cutting device according to the present invention shown in FIG.
When I conducted an experiment with the cutting speed set to 110 seconds, I was able to cut a 110mm wide plate material in about 0.6 seconds.

種の形状の切断を低コストで行うことができる。(Effects of the Invention) As explained above, in the curve cutting device according to the present invention, the traveling speed of the plate material to be cut, the upper and lower convex cutting blade rollers and the convex cutting blades that advance the plate material to be cut in a direction transverse to the plate material to be cut, Since the plate material to be cut can be cut into any curved shape by controlling the speed at which the roller moves forward, it is necessary to prepare a variety of expensive dedicated molds such as press molds. There are no cutting edges, and cutting into various shapes can be performed at low cost using one type of convex and concave cutting roller.
しかも切断形状の変更は、切刃の変換を行わないで簡単

断のため小さな動力で切断が可能となる利点がある。In addition, when cutting is performed by meshing convex and concave cutting rollers, it is possible to cut using a press mold or shearing machine. Since the material to be cut is held down by the roll surface, there is an advantage that the cutting direction of the material to be cut is sharp.Furthermore, since this device does not perform pressing, shearing, etc., there is no noise during cutting. Another advantage is that cutting can be performed with a small amount of power due to transfer cutting.
