Here, the pipe 10 before processing means a pipe having a length of 6 m, for example, and the pipe 20 after processing means four pipes divided into quarters of 1.5 m. In the following description, ) Refers to the pipe 10 before machining.

First, the pipe supplying frame 100 supplies the pipe 10 in a state in which the pipe 10 is seated in the lateral direction before machining. For example, two or more pipes may be provided so as to be spaced apart from each other. As shown in Figs. 5 and 6, Likewise, the upper portion of the pipe feed frame 100 on which the pipe 10 can be placed before machining is sloped downward toward the pipe tilting unit 700 side. Thus, the pre-machined pipe 10 seated on the upper portion of the pipe feed frame 100 rotates toward the pipe tilting unit 700 side along the inclined surface of the pipe feed frame 100 and becomes movable.

Next, the pipe stacking frame 110 is for receiving pipes 4 after being divided into four by the pipe cutting and hole forming unit 600 to be described later and loading them in the horizontal direction. For example, four pipes And an upper portion of the pipe stacking frame 110 on which the pipe 20 is seated after the processing is provided so as to be inclined downward in a direction away from the pipe tilting unit 700.

[

12 and 13, in an initial state in which the pipe 10 is moved from the pipe feed frame 100 to the upper side of the pipe tilting unit 700 and is seated, as shown in Figs. 12 and 13, 412 are spaced apart from the one end of the pipe 10 by a predetermined distance. The control unit (not shown) drives the cylinder 413 so that the push plate 412 presses one end of the unprocessed pipe 10 to move to the pipe rotation unit 420 side. The pipe rotating section 420 is in a state in which the other end of the pipe 10 before machining can be fixed while the push plate 412 moves the pipe 10 before the machining to the pipe rotating section 420 side.

In the embodiment of the present invention, the pusher main body 411 is provided movably on the base rail 120. For example, when the length of the pre-machining pipe 10 is changed, (411) is movable along the base rail (120). Here, the base rail 120 may be a kind of LM guide rail, and the LM block 414 may be provided below the push portion main body 411 so as to be movable with respect to the base rail 120. Here, the reciprocating structure of the LM Guide unit is obvious to a person skilled in the art in the technical field of the present invention, and a detailed description thereof will be omitted.

The base rail 120 has a rack structure. The base rail 411 is rotatably supported by a separate driving motor (not shown) under the pusher body 411 and is coupled with the rack in a tooth- A plurality of spur gears (not shown) that can be moved can be provided.

Next, the pipe rotating part 420 is positioned in the other direction with respect to the base rail 120 on which the pipe tilting unit 700 or the like to be described later is installed, specifically, in a direction opposite to the direction in which the pipe pushing part 410 is installed, And to selectively rotate the pipe 10 by fixing the other end of the pipe 10.

Before the detailed description is made, if the through hole 30 is to be formed in the pipe 10 before machining, the pipe rotating part 420 clamps the pipe 10 before machining, And the hole forming unit 600 perform the forming operation of the through-hole 30. Alternatively, if the pipe 10 is to be cut into four equal parts before machining, the pipe rotating part 420 rotates the pipe 10 in a clamped state before machining, and cuts the pipe 10 by a pipe cutting and hole forming unit 600 A cutting operation is performed.

Therefore, in particular, in order to rotate the pipe 10 before machining, it is preferable to raise the pipe 10 before machining to a certain height above the seating portion of the pipe tilting unit 700, It is preferable to support the pipe 10 from the lower side before machining in a plurality of regions along the longitudinal direction. If the lower side of the pipe 10 can not be supported before machining, the bending of the shape may occur because only the other end of the pipe 10 is clamped to the fixing chuck 421, Problems that are difficult to cut occur.

4, the pipe supporting unit 500 is provided in plurality to be spaced apart from each other so as to selectively support the lower side of the unprocessed pipe 10 connected to the pipe rotating unit 400, A support body 510 provided on the support body 510 for selectively supporting the lower side of the pipe before machining to support the pipe before machining from the lower side, And a cylinder 530 connected to the rotating roller 520 and the bracket to which the rotating roller 520 is coupled to move the rotating roller 520 up and down.

In operation, the rotating roller 520 is positioned below the pipe 10 in a state where the pipe 10 is clamped to the fixing chuck 421 before machining. The cylinder 530 moves up the rotating roller 520 so that the rotating roller 520 moves the pipe 10 before machining to perform the cutting operation of the pipe 10 and the forming of the through hole 30 So as to support the lower portion of the pipe 10 before processing. Since the rotating roller 520 is freely rotatable and comes into rolling contact with the pre-machining pipe 10 in a rotating state, it can sufficiently support the pipe 10 from the underside before machining, So that it can be smoothly performed.

In the embodiment of the present invention, the support body 510 is movably provided on the base rail 120. For example, when the length of the pipe 10 before the modification is changed, the support body 510 Can be moved along the base rail 120. Here, the base rail 120 may be a kind of LM guide rail, and the LM block may be provided below the support body 510 so as to be movable with respect to the base rail 120. Here, the reciprocating structure of the LM Guide unit is obvious to a person skilled in the art in the technical field of the present invention, and a detailed description thereof will be omitted.

Here, each of the first moving part (not shown) and the second moving part (not shown) may include any one of a rack and pinion combination, a cylinder, and an LM guide.

When the through hole 30 is formed in the pipe 10 before machining and the pipe 10 is cut into four equal parts before machining, the through hole 30 is formed in the pipe 10 before machining And then cut into four equal parts.

More specifically, a control unit (not shown) drives a first moving unit (not shown) to form a through hole 30 on the untreated pipe 10, The hole cutting and forming body 620 is moved to a predetermined position for forming the hole cutting and forming body 620. [ The control unit (not shown) drives the second moving unit (not shown) to lower the plurality of plasma torches 630 in a direction approaching the outer surface of the pipe 10 before machining. Then, the plurality of plasma torches 630 form a through-hole 30 while generating a plasma arc. On the other hand, when the through hole 30 is formed, the plurality of plasma torches 630 are restored to the upper side.

Next, the control unit (not shown) drives the first moving unit (not shown) to cut the pre-machined pipe 10 having the through-hole 30 formed therein, 10 and the hole cutting and forming body 620 to a predetermined position for cutting. The control unit (not shown) drives the second moving unit (not shown) to lower the plurality of plasma torches 630 in a direction approaching the outer surface of the pipe 10 before machining. Then, the pipe rotating section 420, specifically, the driving motor 422 is driven to rotate the fixing chuck 421, thereby rotating the pipe 10 before machining at a constant speed. At this time, the rotating roller 520 of the pipe supporting unit 500 is in a state of supporting the pipe 10 from below. Next, a plurality of plasma torches 630 are cut along the circumferential direction of the pipe 10 before machining, generating a plasma arc.
