And a corrugated pipe machined by a cutting and stripping device.

First, as shown in FIGS. 1 to 7, the cutting apparatus of the present invention comprises a feeding unit 100, a cutting unit 200, and an operating unit 300.

The conveyance unit 100 includes at least one conveying roller 110 to convey the corrugated pipe 11.

That is, the conveying unit 100 horizontally arranges a plurality of conveying rollers 110 in two rows, and moves the conveying rollers 110 between the conveying rollers 110 installed on the upper and lower sides by the rotation of the conveying rollers 110.

Thus, the corrugated pipe 11 is moved to the operating part 300 through the conveying part 100.

At this time, the incision part 200 moves the first block 260 forward by driving the main cylinder 210 so that the covering material 12 of the corrugated pipe 11 can be cut in the longitudinal direction after the movement of the corrugated pipe 11 is completed by the operation part 300.

In addition, the blade 250 can be brought into close contact with the covering material 12 through the sub-cylinder 220 installed in the first block 260.

That is, in the cut-off section 200, the main cylinder 210 is driven to move the first block 260 forward after the corrugated pipe 11 is transported and stopped.

Then, the sub-cylinder 220 installed in the first block rotates downward to closely contact the blade 250 coupled to the sub-cylinder 220 to the cover 12.

Thereafter, when the main cylinder 210 is driven to move the first block backward, the blade 250 is cut into the cover material 12 in the longitudinal direction.

Next, the sub cylinder 220 is rotated reversely to rotate the blade 250 upward to separate the blade 250 from the covering material 12, thereby completing the cutting process of the covering material 12.

Here, a portion cut in the longitudinal direction of the covering material 12 by the blade 250 is referred to as a primary cutting portion 13.

The process then cuts the corrugated tube 11 through the operating part 300 and at the same time allows the cover 12 to be completely cut.

The operating part 300 is installed at one side of the conveying part 100 and rotatably installed at the periphery of the through hole 311 of the cutting block 310 through which the corrugated pipe 11 moved by the conveying part 100 passes, And an operating part 300 for cutting the covering material 12 in the longitudinal direction so that the peeling work of the covering material 12 can be more easily achieved.

That is, in the bellows pipe 11 moved by the feeding unit 100, the primary cutting unit 13 is positioned on the operation unit 300, and then the bell pipe 11 is cut by the receiving unit 320 and the cutting unit 360 of the operation unit 300, The secondary incision is made in the longitudinal direction on both sides.

The secondary cutout portion refers to a portion cut in the longitudinal direction on both sides of the primary cutout portion cut in the lateral direction in the covering material 12. The secondary cutout portion is provided at one end of the corrugated pipe 11 through the primary cutout portion 13 and the secondary cutout portion 14 So that the peeling of the coated covering material 12 can be easily achieved.

The operation unit 300 for performing the cutting process of the secondary cutout unit 14 includes a receiving unit 320 and a cutting unit 360.

A pair of rolling rollers 321 are mounted on the periphery of the through hole 311 of the cutting block 310 so as to seat the corrugated tube 11, and a first bracket 322 for rotatably supporting the rolling roller 321 is disposed in the first cylinder 323, respectively.

That is, after the corrugated pipe 11 enters the through hole 311 in the state where the corrugated pipe 11 is positioned at the inner periphery of the through hole 311 of the operating portion 300 so that the receiving means 320 does not interfere with the through hole 311 of the operating portion 300, The first bracket 322 is raised by the first cylinder 323 so that the rolling roller 321 is brought into close contact with the outer peripheral edge of the corrugated pipe 11. [

This allows the corrugated tube 11 to be supported without shaking of the corrugated tube 11 when the cutting and covering member 12 cutting process is performed by the cutting means 360, thereby achieving precise cutting of the secondary cutout 14. [

Thereafter, after the corrugated pipe 11 is cut and the covering material 12 is removed, the first cylinder 323 is driven to lower the pair of rolling rollers 321 to prevent interference with the next corrugated pipe 11 moving into the next operation part 300 do.

In addition, the cutting means 360 includes a cutting blade 361 installed at the periphery of the through hole 311 of the cutting block 310 and corresponding to the receiving means 320, and a second bracket 363 for rotatably supporting the cutting blade 362. 2 cylinder 364. As shown in Fig.

Here, the incision blades 362 are provided on both sides of the cutting blade 361, and the incision blade 362 and the transfer blade 361 are integrally coupled to one shaft, and the diameter of the incision blade 362 is smaller than that of the cutting blade 361 .

That is, when the corrugated pipe 11 is positioned inside the through hole 311 of the operation part 300 and the supporting means 320 is brought into close contact with the outer periphery of the corrugated pipe 11, the second cylinder 364 installed inside the operating part 300 is driven, So that it is in close contact with the surface.

Then, the operation unit 300 rotates to interlock the supporting means 320 and the cutting means 360.

At this time, the supporting means 320 rotates at the outer periphery of the corrugated pipe 11 in a fixed state while the rolling roller 321 is in rolling contact with the covering material 12 of the corrugated pipe 11.

The cutting edge 361 and the cutting edge 362 of the cutting means 360 provided on the opposite side of the receiving means 320 at the inner periphery of the through hole 311 of the operating part 300 are rotated while being rolled and rotated at the outer peripheral edge of the covering material 12 of the corrugated pipe 11.

Here, the cutting edge 361 and the incising blade 362 are gradually moved upward through the second cylinder 364 so that the cutting blade 361 cuts the corrugated tube 11, while the incision blade 362 cuts both sides of the first- Both sides of the primary incision are rotated in the circumference to make a second incision in a circular shape.

Thus, the process of cutting the corrugated tube 11 through the cutting edge 361 and cutting the covering material 12 through the cutting edge 362 is completed.

The fixing unit 400 further includes a fixing unit 400 provided at the front of the operation unit 300 and gripping the corrugated pipe 11 without flowing when the corrugated pipe 11 is cut by the operation unit 300 and the cutting process of the covering member 12 proceeds.

The fixing part 400 includes a third bracket 410 and a through hole 421 formed in the front of the third bracket 410 so as to penetrate through one end of the bending pipe 11. A fixing hole 422 is formed in the outer periphery of the fixing part 400, And a third cylinder 430 vertically installed on the third bracket 410 and capable of fixing the corrugated tube 11 by selectively engaging the pressing means with the insertion hole 422. [

That is, the fixing part 400 is for fixing the corrugated tube 11 without shaking when the corrugated tube 11 is cut and the cutting process of the covering material 12 is performed, and functions to press and hold one end of the corrugated tube 11 penetrating the working part 300.

In other words, when the corrugated tube 11 passing through the actuating part 300 is coupled to the through hole 421 of the fixing part 400, the fixing block 420 is moved downward through the third cylinder 430 so that the fixing block 420 is inserted into the through hole 421 And is pressed against the outside of the corrugated tube 11 to fix the corrugated tube 11 without shaking.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
