【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing a cutting machine 1 equipped with an embodiment of a cutting material fixing device according to the present invention, FIG. 2 is a schematic cross-sectional view thereof, and FIGS. 3 to 6 schematically show the mechanism of main parts. It is a figure.

As shown in FIG. 1, the cutting machine 1 is provided with a recess that is continuous to the left and right as a mounting portion 20 on which a cutting material is mounted. The recess is provided so that the opening is diagonally upward and is inclined downward toward the back. Therefore, the cutting material can be easily inserted from the opening, and the cutting material can be stably stored in the bottom portion.

As shown in FIG. 2, a rotary blade 10 for cutting a cutting material is built in the cutting machine 1, and a motor 11 is driven by a switch operation of an operation panel 40 (FIG. 1). The cutting material can be cut by rotating it and lowering it toward the mounting portion 20. As shown in FIG. 3, a motor 11 for rotating the rotary blade 10 is fixed to a base 12 slidably supported by two support rods 13, and a support rod 13 is provided at the center of the base 12. A screw rod 14 provided in parallel with is screwed into the screw rod 14, and the screw rod 14 is rotated by the driving of another motor (not shown). When the screw rod 14 rotates, the base 12 moves along the screw rod 14, and at the same time, the rotary blade 10 moves. Then, in FIG. 2, the rotary blade 10 is lowered toward the mounting portion 20 by the forward and reverse rotations of the screw rod 14, and is returned to the original position even when raised. In this operation, a reciprocating motion of descending and ascending can be automatically performed by providing a limit switch at the lower end of the support rod 13 with which the base 12 is contacted to switch between forward and reverse rotation of the screw rod 14. . Further, the rotation of the rotary blade 10 can be automatically stopped by providing a switch for stopping the driving of the motor 11 of the rotary blade 10 when the rotary blade 10 returns to the original position.

Now, in the cutting machine 1 equipped with the rotary blade 10 as described above, as shown in FIG. 2, FIG. 4 and FIG. A moving unit 30 that moves back and forth is provided. The moving unit 30 includes a steel plate 32 that moves along the bottom surface of the mounting unit 20, and a holding plate 31 spot-welded to the steel plate 32 in an upright state. The steel plate 32 is slidably supported by a steel material 47 provided on the cutting machine 1, and a screw rod 42 is screwed into the lower portion thereof. The screw rod 42 is connected to a handle 46 attached to the right side surface of the cutting machine 1 via a gear 43, a pulley 44, and a chain belt 45 (FIG. 1, FIG. 2, FIG. 4), and rotation of the handle 46. It is designed to rotate by operation. Therefore, the steel rod 32 can be moved up and down by rotating the screw rod 42 by rotating the handle 46 forward and backward. By vertically moving the steel plate 32, the pressing plate 31 can be moved toward or away from the placing section 20, and the placing section 20 and the moving section 30 can change the three directions of the placed cutting material. The enclosure has a structure in which the cutting material is opened in one direction for inserting the cutting material, and as shown in FIG. 5, the cutting material can be clamped and fixed between one surface of the mounting portion 20 and the holding plate 31. The steel plate 32 is provided with a notch 33, which is the part through which the rotary blade 10 passes.

As shown in FIG. 5, the holding plate 31 is inclined so as to narrow its width toward the opening into which the cutting material is inserted. Therefore, the cutting material is securely fixed without escaping toward the opening, and the cutting material does not shake due to vibration caused by contact between the cutting material and the rotary blade 10 during cutting. In particular, in the case where the cutting material has a shape in which one surface is opened, such as the wiring duct X1, since the opening surface side cannot be pressed, it is effective in securely fixing such cutting material. . Further, as shown in FIG. 6, even when the round mold material X2 that easily escapes to the outside is cut, the pressing plate 31 presses inward on the side opposite to the opening side, so that reliable fixing can be performed. In addition, the inclination angle θ of the pressing plate 31 is set to 85 degrees in this case. Further, since the holding plate 31 acts as a holding member for the cutting materials X1 and X2, the end portions are bent and formed in an angle shape as shown in FIG. 4, and the width of the base portion is made thicker as shown in FIG. As a result, the structure and strength of the holding plate 31 are enhanced.

As shown in FIG. 2, the cutting machine 1 is provided with a transparent cover 15 that covers the opening of the mounting portion 20. The cover 15 is for ensuring the safety of the work at the time of cutting the cutting material placed on the placing portion 20 and for preventing cutting chips from flying. The cover 15 is connected to the base 12 by a wire 16, and is adapted to move back and forth to the mounting portion 20 in correspondence with the movement of the rotary blade 10 to and from the mounting portion 20. That is, when the rotary blade 10 starts to rotate and moves toward the mounting portion 20, the cover 15 also moves toward the mounting portion 20, and during cutting, the mounting portion 20 is covered and After that, when the rotary blade 10 moves away from the mounting portion 20, the cover 15 also moves away from the mounting portion 20. The front end of the cover 15 is arranged in front of the rotary blade 10 so that the cover 15 enters the placing portion 20 before the rotary blade 10.

Next, a usage example of the cutting machine 1 equipped with the cutting material fixing device will be described. First, the cutting materials X1 and X2 are mounted on the mounting portion 20 of the cutting machine 1 so that the cutting position matches the passage position of the rotary blade 10. Next, the handle 46 provided on the right side surface of the cutting machine 1 is rotated to lower the moving unit 30 and press the cutting materials X1 and X2 with the pressing plate 31 to fix the cutting materials X1 and X2. When the moving part 30 is made of the steel plate 32 provided with the notch 33 through which the rotary blade 10 passes, the cutting materials X1 and X2 on both sides to be cut by the rotary blade 10 can be simultaneously pressed. Therefore, the fixing work can be performed very easily.

Next, after the cutting materials X1 and X2 are fixed, the switch 41 of the operation panel 40 is turned on and the rotary blade 10 is rotated to perform the cutting work. This cutting operation can be automatically performed by providing various limit switches and the like as described above. In addition, by combining with the cover 15, it is possible to ensure the safety of work and prevent the deterioration of the environment due to the scattering of cutting chips in the work place.
