DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing a cutting machine 1 provided with an embodiment of a cutting material fixing device according to the present invention, FIG. 2 is a schematic sectional view thereof, and FIGS. 3 to 6 schematically show mechanisms of main parts. It is.

As shown in FIG. 1, the cutting machine 1 is formed with a concave portion which is continuous on the left and right as a mounting portion 20 for mounting a cutting material at a central portion thereof. The recess is provided so that the opening is inclined obliquely upward and descends downward. Therefore, the cutting material can be easily inserted from the opening, and the cutting material can be stably stored at the bottom.

A rotary blade 10 for cutting a cutting material is built in the cutting machine 1 as shown in FIG. 2, and a motor 11 is driven by a switch operation of an operation panel 40 (FIG. 1). , And is lowered toward the mounting portion 20 to cut the cutting material. As shown in FIG.
The motor 11 for rotating the rotary blade 10 has two support rods 13.
A screw rod 14 provided in parallel with the support rod 13 is screwed into the center of the base 12, and the screw rod 14 is connected to another motor (see FIG. 1). Not shown)
It is designed to rotate by the drive of. Screw rod 14
Rotates, the base 12 moves along the screw rod 14,
At the same time, the rotary blade 10 moves. In FIG. 2, the rotary blade 10 is lowered toward the mounting portion 20 by the forward / reverse rotation of the screw rod 14, and is raised to return to the original position. This operation is
By providing a limit switch at the lower end of the support rod 13 to switch between forward and reverse rotation of the screw rod 14 by contacting the base 12, reciprocation of descending and ascending can be automatically performed.
When the rotary blade 10 returns to the original position, the rotary blade 10
By providing a switch for stopping the driving of the motor 11, the rotation of the rotary blade 10 can be automatically stopped.

In the cutting machine 1 provided with such a rotary blade 10, a portion on which a cutting material is placed is shown in FIGS.
As shown in FIG. 5 and FIG. 5, a moving unit 30 that moves toward and away from the mounting unit 20 is provided. The moving unit 30
A steel plate 32 to be moved along the bottom surface of the mounting portion 20, and a holding plate 31 spot-welded on the steel plate 32 in an upright state;
And The steel plate 32 is slidably supported by a steel material 47 provided in the cutting machine 1, and a screw bar 42 is screwed into a lower portion thereof. The screw rod 42 is a gear 43, a pulley 44,
It is connected to a handle 46 attached to the right side surface of the cutting machine 1 via a chain belt 45 (see FIGS. 1, 2,
4), the handle 46 is rotated by a rotating operation. Therefore, the screw rod 42 is rotated by the normal rotation and the reverse rotation of the handle 46, whereby the steel plate 32 can be moved up and down. Due to the vertical movement of the steel plate 32, the presser plate 31 is brought closer to the mounting portion 20,
As shown in FIG. 5, the placing section 20 and the moving section 30 form a structure in which the placing section 20 and the moving section 30 enclose three directions of the placed cutting material and open in one direction for inserting the cutting material. The cutting material can be clamped and fixed between one surface of the mounting portion 20 and the pressing plate 31. In addition, the steel plate 32 is provided with a cut portion 33, and the cut portion 33 is a portion through which the rotary blade 10 passes.

As shown in FIG. 5, the holding plate 31 is inclined so as to decrease its width toward the opening into which the cutting material is inserted. For this reason, the cutting material is securely fixed without escaping toward the opening.
The cutting material is not shaken by the vibration caused by the contact with the material. In particular, in the case of a form in which the cut material has an open surface such as the wiring duct X1, since the pressing surface cannot be pressed on the open surface side, it is effective to securely fix such a cut material. In addition, as shown in FIG. 6, even when cutting the round shape member X2 that is easy to escape to the outside, the holding plate 31 is pressed inward on the side opposite to the opening side, so that it can be securely fixed. In this case, the inclination angle θ of the holding plate 31 is 8 in this case.
It is set to 5 degrees. The holding plate 31 is made of a cutting material X1,
In order to act as a presser for X2, the end is bent into an angle as shown in FIG. I have.

As shown in FIG. 2, the cutting machine 1 is provided with a transparent cover 15 for covering the opening of the mounting portion 20. The cover 15 is used to ensure the safety of work when cutting the cutting material placed on the placing portion 20 and to prevent flying chips. The cover 15 is connected to the base 12 by a wire 16, and corresponds to the advance and retreat of the rotary blade 10 to and from the mounting portion 20.
It moves to 0. That is, the rotary blade 10
When starts to rotate and moves toward the mounting portion 20,
The cover 15 also moves toward the mounting portion 20, and is in a state of covering the mounting portion 20 during cutting. When the rotary blade 10 moves away from the mounting portion 20 after cutting, the cover 15 also moves from the mounting portion 20. It is designed to move away. Note that the tip of the cover 15 is disposed forward of the rotary blade 10 so that the cover 15 enters the mounting portion 20 before the rotary blade 10 enters.

Next, an example of use of the cutting machine 1 provided with the above-mentioned cutting material fixing device will be described. First, the cutting materials X1 and X2 are placed on the placing portion 20 of the cutting machine 1 with the cutting position adjusted to the passing position of the rotary blade 10. Next, the handle 46 provided on the right side surface of the cutting machine 1 is turned to lower the moving unit 30 and press the cutting materials X1 and X2 with the holding plate 31 to fix the cutting materials X1 and X2. In addition, the moving part 30 is the rotary blade 10
In the case of the steel plate 32 provided with the cut portion 33 through which the cutting material X passes, the cut material X on both sides cut by the rotary blade 10
Since X1 and X2 can be pressed down at the same time, the fixing operation can be performed very easily.

Next, after fixing the cut materials X1 and X2, the switch 41 of the operation panel 40 is turned on, and the rotary blade 10 is rotated to perform a cutting operation. This cutting work, as described above,
This can be done automatically by providing various limit switches and the like. In addition, the safety of the work can be ensured by the combination with the cover 15, and furthermore, the environmental deterioration due to the scattering of the cuttings in the work place can be prevented.
