[

The moving block 144 is configured at one end of the second frame 142 and configured to reciprocate so that the cutting edge 146 is brought into close contact with the outer periphery to cut the drum 1, When done, let it spread.

The movable block 144 is formed with a fixed clamp 145 which is supported by the second frame 142 and fixes a position to be reciprocated. The fixing clamp 145 prevents the fixing position from being changed by vibration or other external impacts generated when the cutting blade 146 cuts the drum 1.

The cutting edge 146 is cut by cutting the portion of the cutting edge 146 which is in close contact with the outer peripheral edge of the drum 1 while being rotated by the rotational force of the rotary portion 148. The cutting blade 146 is preferably formed in a saw tooth shape to facilitate cutting of the drum 1. Of course, the present invention is not limited thereto, and any shape can be used as long as the drum 1 can be easily cut.

The rotary part 148 provides a rotational force to the cutting blade 146 supported by the moving block 144 so that the drum 1 is cut. The rotation unit 148 is configured to rotate by a motor that provides a rotational force by an electric current provided from the outside, and a power transmission medium that rotates the prime mover and the driven pulley. Of course, the present invention is not limited thereto, and any means that can apply a rotational force to the cutting edge 146 can be used.

The side idle rolls 150 support the side surface when the drum 1 rotates to help smooth rotation.

The side idle roll 150 is composed of a third frame 152 and one or more rolls 154 formed on one side of the third frame 152.

The third frame 152 is configured to support the side surface of the drum 1 while supporting the roll 154 to rotate freely.

The roll 154 is supported to rotate freely on the third frame 152.

The rolls 154 are preferably formed in a plurality of positions symmetrical with respect to the center of the drum 1 so as to smoothly support the circular drum 1. In addition, a soft synthetic resin may be formed on the outer circumference of the roll 154 in order to prevent the friction coefficient from being high and being damaged so as to facilitate rotation with surface contact with the drum 1.

The drawing unit 160 treats the cut sharp portion of the drum 1 so as not to be injured in use.

The drawing unit 160 includes a fourth frame 162, a second hinge 164 provided on one side of the fourth frame 162, a second hinge 164 disposed on one side of the fourth frame 162, A link 166 and a drawing die 168 formed at one end of the rotary link 166. [

The rotary link 166 rotates the second hinge 164 at a predetermined angle to position or release the drawing die 168 at the cutting position of the drum 1.

The drawing die 168 removes burrs generated at the cut portion of the drum 1. [ In addition, the drawing die 168 bends a cut portion of the drum 1 to a certain extent to smoothly form a sharp cut portion, thereby preventing injury.

The punching press (170) is a press forming a hole in the cut drum (1).

Further, the punching press 170 is fixed to one side of the first frame 122.

A positioning pin 172 is formed at the lower end of the punching press 170 so as to form a hole at the same position in a direction symmetrical to the hole formed by the punching of the punching press 170.

The operation state of the drum cutter constructed as described above will be described below.

First, the drum 1 is placed in the housing 112 of the lower chuck 110, as shown in Fig.

When the tightening handle 116 provided on one side of the housing 112 is rotated, the plurality of troughs 114 interlock with each other to tighten the lower reinforcing bolt 4 of the drum 1.

A plurality of hooks 126 provided on the upper chuck 120 are pulled so as to be caught by the upper clamping pawl 4 of the drum 1 and the repulsive force due to the elasticity of the elastic rotating part 124 acts The pulled hook 126 is pulled up by the repulsive force of the elastic rotation part 124. At this time, the ends of the plurality of hooks 126 are fastened to the reinforcing flange 4 around the hinge 128 provided at the end of the elastic rotation part 124 to complete the fixing of the upper end of the drum 1.

When the moving block 144 of the cutting portion 140 is moved to the drum 1 side, the cutting edge 146 is held in close contact with the outer circumference of the drum 1. In addition, the moving block 144, to which movement has been completed, is fixed in its moving position by the fixing force of the fixed clamp 145. [

When the motor 132 of the driving unit 130 generates a rotational force, a rotational force is transmitted from the driven gear 134 to the driven gear 136, so that the driven gear 136 is fixed to the housing 112, So that the drum 1 is rotated.

5, a rotating force is generated in the rotating part 148 provided in the cutting part 140, and the cutting edge 146 is rotated through the rotating part 148 to cut the outer peripheral edge of the drum 1 And cut.

It is preferable that the cutting direction of the drum 1 and the cutting edge 146 are opposite to each other so that cutting of the drum 1 is facilitated by the cutting edge 146.

As shown in FIG. 6, when cutting of the drum 1 is completed through the above process, the cut drum 1 fixed by the upper chuck 120 is removed.

7, the lower chuck 110 is rotated by the rotational force of the driving unit 130 so that the drawing die 168 of the drawing unit 160 is positioned at the cutting position of the drum 1 And rotates the rotating link 166.

In addition, as the drum 1 is rotated by the rotation of the lower chuck 110, the cutting portion of the drum 1 is bent by the drawing die 168.

When a hole is to be drilled in the cut drum 1, a part of the drums 1 cut into the punching press 170 formed on one side of the first frame 122 is inserted, Lt; / RTI >

Thereafter, in order to perforate a hole in a direction symmetrical to the perforated hole, a perforated hole is formed in the positioning pin 172 formed below the punching press 170, and the upper part of the positioning pin 172 A hole having a symmetrical direction can be formed in the drum 1 by perforating the hole with the punching press 170 located in the drum 1.

The above description is only one embodiment for implementing the drum cutter, and the present invention is not limited to the above embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
