2, the large-sized high-speed pipe cutter according to the present invention comprises a transfer unit 100, a pressing unit 200, a stopper unit 300, a pipe fixing unit 400, and a cutting unit 500.

The pushing portion 200 allows the pipe to move to the cutting portion side and the stopper portion 300 moves the pipe to the cutting portion side. The pipe fixing part 400 restricts the pipe moving position, and the pipe fixing part 400 rotatably supports the pipe from the upper side, so that the cut part 500 can cut the pipe.

Fig. 2 shows an overall view of a large-sized pipe high-speed cutter, which will be described with reference to Figs. 3, 4, 5, 6, 7, 8 and 9, If there is no mention, it can be understood with reference to FIG.

The transfer unit 100 is a device that can move the pipe in the longitudinal direction to move to the cutting unit side and to rotate the pipe when cutting the pipe.

3, the conveying unit 100 includes a conveying roller 120 provided on the elevating means 110 installed on the frame F to support the pipe so as to be movable in the longitudinal direction, And a rotating roller 140 mounted on the lower end of the lifting means to receive the pipe, and connected to the power of the motor M to rotate and support the pipe.

Here, the frame F is divided into long pieces to support the length of the pipe P, and the elevating means 110 constituted by a cylinder device for vertically moving up and down by a hydraulic cylinder at regular intervals is installed And a conveying roller 120 rotatably supported at both sides of the lower portion of the pipe is formed at an end of the elevating means so as to unload the initial pipe and to move the pipe P longitudinally do.

Since the pipe P can be unloaded and moved in the longitudinal direction, there is no interference when the pipe is unloaded, and the pipe can be quickly moved toward the pipe fixing part 400 and the cut part 500.

Then, when the elevating means is lowered after the pipe is conveyed by the conveying roller 120, the pipe is seated on the rotary roller 140 provided on the frame F to be able to rotate.

Since the rotary roller 140 is configured to rotate and cut the pipe, the cutting unit 500 will be described. The pressing unit 200 is required to move the pipe.

The pushing portion 200 pushes the pipe to move the pipe fixing portion 400 and the cutting portion 500, and FIG. 4 is an enlarged view of the pushing portion of FIG.

4, the pressing part 200 is provided at one side of the conveying part and is advanced by the reciprocating means 220 to be closely attached to one end of the pipe, and is supported by a ball caster 242 And the pressing member 240 is provided.

The reciprocating means 220 includes a forward / reverse motor 222, a chain 224 installed on the frame and power-connected to the forward and reverse motors, a bracket 226 fixed on the chain, The bracket can be moved forward and backward by the rotation of the forward and reverse motors 222 so that one side of the pipe can be pressed and pushed by the pressing member 240 connected thereto.

The pressing member 240 is provided in the shape of a bar in the horizontal direction, and the ball caster 242 formed at the end can be positioned at the end of the pipe to support the rotation.

The pipe is pressed and moved by the pressing member 240, and the movement of the pipe is restricted by the stopper 300 on the opposite side.

5, which is an enlarged view of the stopper portion of FIG. 2, the stopper portion 300 is provided on the other side of the conveying portion and is moved toward the other end of the pipe by the position adjusting means 320, And a horizontal moving member 340 having a ball caster 342 at an end thereof for restricting the movement of the pipe moved by the rotation and supporting the rotation.

The position adjusting means 320 includes a lower frame 322, a screw shaft 324 rotated by a handle knob 323 on an upper portion of the lower frame, And a vertical cylinder 328 installed on the pedestal 326 for moving the horizontal moving member up and down.

In other words, the position of the horizontal moving member can be adjusted by rotating the handle knob 323, and the height of the horizontal moving member can be adjusted by raising the vertical cylinder 328 The position of the horizontally moving member can be determined at an appropriate position according to the size of the pipe.

In order to confirm the moving distance of the pedestal 326, a ruler is formed on the lower frame 322.

Both side ends of the pipe are supported by the pressing portion 200 and the stopper portion 300 and are easily rotated by the ball caster. Then, the pipe fixing portion 400 rotatably supports the upper side of the pipe.

6 is a side view of the primary clamp side view of FIG. 2. Referring to FIG. 6, the pipe fixing portion 400 is lowered by a lifting means composed of a cylinder device, And FIG. 7 is a side view of the secondary clamp side view of FIG. 2. The primary clamp 420 is spaced apart from the primary clamp and descended by a lifting means composed of a cylinder device, And a secondary clamp 440 provided with a roller 442 for performing a clamping operation.

The upper portion of the pipe can be rotatably supported by the pipe fixing portion 400, and can be cut by the cut portion 500.

The cutting part 500 is provided so as to be movable upward and downward from the upper part of the feeding part and is capable of cutting the pipe by a cutting blade descending between the primary clamp and the secondary clamp and rotating simultaneously with the rotation of the pipe by the rotating roller .

As shown in FIG. 8, the cutting blade 522 is a band saw that rotates in an endless track by both rolls, and a circular saw can also be used.

As shown in FIG. 9, the feeding cylinder 100 further includes a discharging cylinder 600 for pressing the cut portion of the pipe so as to be separated from the rotating roller. The cut pipe is evacuated.

Therefore, in the present invention, a pipe is cut by a band saw which rotates and simultaneously rotates the pipe so that a large-sized pipe is transported in the longitudinal direction and then rotatably supported at the lower, upper and both ends, Accuracy can be increased.

As described above, it can be seen that the present invention is based on the basic technical idea of providing a high-speed pipe cutter of a large-sized pipe, and, within the scope of the basic idea of the present invention, Of course, many variations are possible.
