A holder member 40c is further provided on the body 40 provided with the table member 40b so as to prevent the flat steel from being cut off. The holder member 40c includes a holder body 40c coupled to the body 40, And a stopper 40c-2 that is screwed vertically to the holder body 40c-1 and moved up and down by the rotation direction.

As shown in FIG. 2, the blade unit 30 includes an angle cutting blade 31 for cutting an angle and a composite cutting blade 32 for cutting a flat iron and a pipe. The angle cutting blade 31, Like shape of an angle, and the angle insertion hole 44 is also formed as a V-shape.

2, the combined cutting blade 32 includes a blade body 32-4 formed at a lower end thereof with a flat cutting member 32-2 for cutting a flat iron, And a pipe cutting member 32-1 for cutting the pipe at the inner upper end portion of the insertion support hole 32-3 while forming the insertion support hole 32-3.

The insertion support hole 32-3 is formed to have a cubic shape with a half point of the entire area and with the vertex point facing downward so as to cut the square pipe and to cut the circular pipe And is formed at regular intervals.

The operation of the present invention having the above-described structure can be explained by dividing into three cutting operations. First, as shown in FIGS. 4A and 4B, the pipe cutting method is to cut a square pipe or a circular pipe A pipe is inserted into the guide hole 40a-1 of the pipe supporting member 40a provided on the front portion of the front block 40-1 and is inserted into the pipe insertion hole 42 of the front block 40-1 And passes through the blade cutting means 30 connected to the block body 20 and the pipe cutting space 401 of the rear block 40-2.

The pipe supporting member 40a supports the pipe so as to secure the stability in supplying and cutting the pipe. For example, the inserted pipe can be pushed into the block with a small force, and the pipe can be gripped without being shaken when it is cut.

The pipe is inserted into the guide hole 40a-1 of the pipe supporting member 40a, the pipe insertion hole 42 of the front block 40-1, the rear block 40-2 and the front block 40-1 The cylinder means 10 is operated to cut the pipe sequentially fitted in the blade cutting space portion 401 of the blade block 30 and the rear block 40-2 inserted into the blade insert space 41 When the cylinder rod is lowered, the block body 20 connected to the cylinder means 10 presses the spring means 50 and descends.

At this time, when the block body 20 is lowered, the blade means 30 provided on the lower surface of the block body 20 also moves downward. The blade unit 30 includes an angle cutting blade 31 for cutting an angle and a composite cutting blade 32 for cutting a flat iron and a pipe as shown in FIGS. 2 and 3A. So that the pipe can be cut using the pipe 32.

The operation of the compound cutting blade 32 is such that the pipe is inserted into the pipe insertion hole 42 of the front block 40-1 and the guide hole 40a-1 of the pipe supporting member 40a, Since the insertion support hole 32-3 is formed as a long hole, the composite cutting blade 32 is lowered in a state where the pipe is inserted, The pipe is cut by the cutting member 32-1 and another pipe cutting member on the body.

That is, the pipe is cut by the intersection of the pipe insertion hole 42 of the front block 40-1 and the pipe cutting member 32-1 provided at the inner upper end of the insertion support hole 32-3, Is discharged to the lower portion of the pipe cutting space portion (401).

When the pressing force of the cylinder means 10 is released when the pipe cutting is completed and the restoring force of the cylinder means 10 and the block body 20 are moved upward by the elastic force of the spring means 50, .

On the other hand, as shown in FIGS. 5A and 5B, the flat steel cutting method is a method in which flat steel is placed on a table member 40b of a "┣" shape attached to the front surface of a front block 40-1, The table member 40b supports the workpiece inserted into the flat steel insertion hole 43 formed at the lower end of the front block 40-1.

When the flat iron is pushed into the flat steel insertion hole 43 as described above, when the cylinder means 10 is operated to press the block body 20 downward, the blade means 30 is also lowered and the blade means 30 The flat steel is cut by the flat steel cutting member 32-2 provided at the lower end of the composite cutting blade 32 as one.

A pipe cutting member and a flat steel member having the same or symmetrical structure as that of the pipe cutting member 32-1 and the flat steel cutting member 32-2 provided on the compound cutting blade 32 at the time of cutting the pipe and flat steel, So that the pipe cutting member 32-1 is cut as in press punching and the cutting by the flat steel cutting member 32-2 is performed as in cutting the scissors.

The flat steel cutting member installed on the body 40 is installed in a horizontal state, but the flat steel cutting member 32-2 provided on the compound cutting blade 32 is inclined at a predetermined angle. The reason for this is that it is not cut down at once but cut like scissors.

At this time, the stopper 40c-2 is vertically screwed to the holder body 40c-1 provided at the upper end of the flat iron insertion hole 43 to adjust the distance from the table member 40b according to the thickness of the flat iron. The reason for this is to prevent the cutting edge of the workpiece from being lifted due to the pressing force of the blade means 30.

On the other hand, the cut flat steel is discharged down to the lower portion of the pipe cutting space portion 401. When the pressing force of the cylinder means 10 is released after the flat steel cutting is completed, the blade means 20 is restored to its original position when the block body 20 is moved upward by the elastic force of the spring means 50.

Finally, as shown in FIGS. 6A and 6B, the angles are cut by an angle insertion hole 44 and a fitting hole 404 formed in the front block 40-1 and the rear block 40-2 The workpiece to be cut, that is, the angle is inserted.

When the insertion of the workpiece is completed, the cylinder unit 10 is operated to lower the cylinder rod, so that the block 20 connected to the cylinder unit 10 presses down the spring means 50.

At this time, when the block body 20 is lowered, the blade means 30 provided on the lower surface of the block body 20 also moves downward. As shown in FIG. 2, the blade unit 30 includes an angle cutting blade 31 for cutting an angle and a composite cutting blade 32 for cutting a flat iron and a pipe. The angle cutting blade 31 So that the angle is cut.

The angles are cut at angles in the angle insertion holes 44 and the insertion holes 404 provided in the front block 40-1 and the rear block 40-2, And is cut by the pressing force of the angle cutting blade 31 that has been formed.

In this case, the size of the script is equal to the thickness t of the angle cutting blade 31, and the reason why the script is generated is that the angle cutting portion is formed at a right angle.

On the other hand, when the angle cutting is completed, when the pressing force of the cylinder means 10 is released, when the block is moved upward by the elastic force of the spring means, the blade means is restored to its original position.
