The operation state of the cutting machine of the present invention at each step operated in the above order will be described once again with reference to FIGS. 3 to 5.

That is, in the power applying step (S100), the user applies power to the cutter. In this case, when the cutter cuts only one end portion of the window frame aggregate, the operation selector switch 100 of one cutter body housing 190 is turned on, and two cutter body housings are cut at the same time. Turn on the operation selector switch 110 of (190).

When operating the operation selection switch 110 in this way, while the power is applied to the cutting motor 122, the rotary saw blade 121, which is the cutting unit 120, starts to operate while rotating at a high speed. At this time, the rotary saw blade 121 is preferably continuously operated regardless of the aggregate cutting. This is to prevent malfunction or failure of the cutting motor 122 due to frequent operation and stop.

Thereafter, the user places the cut aggregate on the shelf of each of the cutter body housings 190.

Next, the operation switch 130 is turned on. (ON) At this time, the operation switch 130 is a foot switch for the user's convenience. When the user presses the switch once, the operation signal is applied. Will be.

When an operation signal is generated by the operation switch 130, the control unit 145 receiving the operation signal continuously transmits a pushing operation signal to the pneumatic pump 150.

The pneumatic pump 150 receives the push operation signal by the control unit 145 transmits the pneumatic pressure of the same pressure to the pneumatic cylinders 160, 170, 180 connected to the next stage. As is well known to those skilled in the art, the pneumatic pump 150 at this time is preferably used an electronically controlled pneumatic pump operated by the control of the electrical signal.

The fixed pneumatic cylinders 170 and 180 of the pneumatic cylinders that receive the pneumatic pressure by the pneumatic pump 150 first complete the pushing operation. This is because the internal volume of the fixed pneumatic cylinders 170 and 180 is smaller than the internal volume of the cut moving pneumatic cylinder 160 is made sequentially. At this time, two or more fixed pneumatic cylinders 170 and 180 are preferably used as shown in FIG. 3, in order to stably fix the aggregate. Also, in one embodiment, the internal volume of the fixed pneumatic cylinders 170 and 180 versus the internal volume of the cut moving pneumatic cylinder 160 is preferably set to 1: 3.

Thereafter, the pneumatic pressure is sequentially applied to the cutting unit moving pneumatic cylinder 160 to move the cutting unit 120 including the cutting motor 122 and the rotary saw blade 121 as shown in FIGS. 4 and 5. At this time, the cutting unit 120 is the rotary saw blade 121 is being rotated at a high speed, so that the aggregate is cut while proceeding in the aggregate direction.

At this time, when the cutting unit 120, which is moved by the set distance, is moved to the end, it comes into contact with the reset switch 140 located at the end and presses the switch to generate a signal.

As such, the signal generated by the reset switch 140 is input to the controller 145, and accordingly, the controller 145 inverts and outputs the pull operation signal, which is the opposite signal, to the pneumatic pump 150.

The pneumatic pump 150 receiving the pull operation signal from the controller 145 transmits the pneumatic pressure so that each of the pneumatic cylinders 160, 170, 180 performs the pull operation.

At this time, the fixed pneumatic cylinders 170, 180 of the pneumatic cylinders 160, 170, 180 that enter the pulling operation first complete the operation to release the aggregates, and then the cut moving pneumatic cylinder 160 operates. Upon completion, the cutout 120 returns to its original position.

Afterwards, if the user has more aggregates to work with, the aggregates are placed, and the cutter is operated by pressing the foot switch, which is an operation switch 130 again.

According to the present invention, the cutter can be controlled by a simple electric circuit and only a switch, and when the user applies an operation signal using the switch at the beginning of operation, the cutting operation is automatically performed, and thus the work and management can be easily performed. It is obvious that this is a beneficial invention.
