[ 0021 ]
Next, the operation of the perforation / cutting device in the embodiment of the invention will be described.
In the drilling machine 2, the drill 6 can drill the rod 6 by rotating, striking and feeding the rod 6. Since the position of the drilling machine 2 can be adjusted by moving the slide base 9 with the hydraulic cylinder 10, the drilling position and the drilling interval can be adjusted freely.
[ 0022 ]
In the wire saw device 3, the cutting wire 22 suspended endlessly by the guide pulleys 15, 16, 17, 18, 19, 20 and the drive wheel 21 can be cut by being driven by the motor 23 via the drive wheel 21.

[ 0023 ]
The rod guide 25 is fixed to a support member 24 fixed to the abutment 11, and the advance / retreat rod 26 is slidably inserted into the rod guide 25. When the angle of the table 11 is adjusted, the advance / retreat lever 26 is also moved and adjusted along with it. At the same time, the punching machine 2 provided on the abutment 11 also moves. In this example, when the hydraulic cylinder 13 is set to the extended position, the center position of the advancing / retracting rod 26 that supports the cutting wire 22 via the guide pulleys 15, 16, 17, 18 is the hole core drilled by the drilling machine 2. Is set to match.
[ 0024 ]
Therefore, after drilling with the drilling machines 2 and 2 in the state shown in the figure, when the hydraulic cylinder 13 is moved to the extended position, the abutment 11 moves by a predetermined angle, the drilling machine 2 moves outward from the drilling position, and the wire saw device 2 The center position of the advance / retreat rod 26 is moved to a position that coincides with the drilled hole core. Therefore, when the wire saw device 3 is driven, as shown in FIG. 5, the advancement / retraction rod 26 can enter the object to be cut, for example, the perforation 35 of the continuous wall 34, and the perforation 35, 35 is cut by the cutting wire 22. it can.
When the diameter of the perforation 35 is small and the diameters of the advancement / retraction rod 26 and the guide pulleys 15 and 16 are large, and the advancement / retraction rod 26 cannot enter the perforation 35, wrap a plurality of holes 35a, 35b as shown in FIG. Drill and allow advance / retreat 26 to enter.
[ 0025 ]
FIGS. 7A, 7B, 7C, and 7D illustrate cutting patterns. Reference numeral 35 denotes perforations and 36 denotes a cutting line, and various cutting patterns can be employed in the present invention.
[ 0026 ]
Next, an example of the operation sequence of the drilling and cutting device will be described.
(1) This apparatus is set and waits in the state of FIG. In this state, the hydraulic cylinders 8, 13, 33 are in the contracted position, and the hydraulic cylinder 27 is in the extended position.
(2) Then, when the hydraulic circuit is opened and the operation start button is turned ON, the rod 6 and the bit 7 start to rotate by the motor of the drill head 5 of the drilling machine 2.
[ 0027 ]
(3) After time-up (after 2 seconds in this example), the hydraulic cylinder 8 is activated and the drill head 5 starts to advance.
(4) As a result, the rod 6 also moves forward, and when the bit 7 attached to the tip of the rod 6 hits the perforated surface and detects an increase in the pressure of the hydraulic cylinder 8, the drill head 5 starts to be hit. 7 is given rotation, striking and advancement. At this time, drilling is performed while the rod 6 is added according to the drilling depth.
[ 0028 ]
(5) When the drilling progresses and the extension of the hydraulic cylinder 8 is detected, the punching of the drilling machine 2 is stopped, and the contraction of the hydraulic cylinder 8 is started.
(6) With this contraction of the hydraulic cylinder 8, the drill head 5 moves backward and the rod 6 and the bit 7 are also returned to their original positions.
(7) When the hydraulic cylinder 8 reaches the limit, it is stopped, and the motor of the drill head 5 is also stopped. This completes the drilling operation.
[ 0029 ]
(8) Next, the hydraulic cylinder 13 operates to rotate the abutment 11. When the hydraulic cylinder 13 reaches the extended position, it stops. As a result, the advancement / retraction rod 26 of the wire saw device 3 is set at the drilled hole core position.
(9) The hydraulic cylinder 33 starts to extend and presses the machine frame 28 to constantly apply tension to the cutting wire 22.
[ 0030 ]
(10) After the time is up, the rotation of the motor 23 and the hydraulic cylinder 27 are activated to start contracting. As a result, the advancement / retraction rod 26 advances, and the wire saw device 3 constituted by the guide pulleys 15, 16, 17, 18, 19, 20 and the cutting wire 22 suspended on the drive wheel 21 advances. Then, since the tip of the advancement / retraction rod 26 can enter the drilling by the punching machine 2, the cutting wire 22 to be driven comes into contact with the workpiece and starts cutting.
(11) When the cutting progresses and the hydraulic cylinder 27 reaches the contracted position, the hydraulic cylinder 27 is temporarily stopped, and this time an extension operation is started.
[ 0031 ]
(12) When the hydraulic cylinder 27 reaches the extended position, it is stopped, the contraction operation of the hydraulic cylinder 13 starts and returns to the original position, the rotation of the motor 23 is stopped, and the operation of the hydraulic cylinder 33 is also stopped. The cutting operation ends.
The above operations are all automatically performed by providing detection means such as limit switches and sensors.
[ 0032 ]
In this apparatus, although there are two drilling machines 2, the same operation is performed, and although there are two hydraulic cylinders 27 and advance / retreat levers 26 of the wire saw apparatus 3, the same operation is performed.
[ 0033 ]
FIG. 8 is a plan view of a perforating / cutting device showing another embodiment of the present invention. This example is a case where the wire saw device 3 is provided outside the two punching machines 2 and 2, and the others are the same as those of the above-described embodiment. Is omitted.
In this example, when the perforating machines 2 and 2 are tilted inward after completion of the perforation, the center position of the advancing and retracting rod 26 that supports the cutting wire 22 comes to coincide with the hole core perforated by the perforating machine 2.
[ 0034 ]
【The invention's effect】
As described above in detail, the present invention has the following effects.
(1) Since the punching machine and the wire saw device are combined and combined, and the drilling by the punching machine and the operation of cutting by the wire saw device using the drilling can all be performed automatically, it is possible to cut quickly and effectively.
[ 0035 ]
(2) In addition, cutting with a wire saw device is performed using holes drilled by a drilling machine, that is, continuous drilling is performed while two holes are drilled on one plane and two advance and retreats are entered. Therefore, the cutting operation can be performed even on a single continuous wall surface or in a narrow space.
[ 0036 ]
(3) In addition, drilling with a drilling machine is performed at the same time, and the drilling is performed with a wire saw device, and it is necessary to continuously wrap the holes in the cutting direction and wrap holes. Therefore, it is possible to carry out drilling and cutting work without the need for skill because all work can be performed automatically.
[ 0037 ]
(4) Further, the cutting width that can be cut by one operation can be easily adjusted by adjusting the interval between the two drilling machines, and can correspond to various work areas.
[ 0038 ]
(5) Since the perforating and cutting apparatus of the present invention is a compact unit of the perforating machine and the wire saw apparatus, it can be freely mounted on a self-propelled carriage, an elevating stage, etc., including horizontal, vertical and ceiling surfaces. Continuous cutting at an angle is possible. In addition, transportation and positioning in a narrow space are easy.
[ 0039 ]
(6) Furthermore, since the centering of the forward / backward movement and the hole core drilled by the drilling machine can be performed only by adjusting the pivot of the abutment, the operation is easy and efficient.
