Description

[0001] PIPE CUTTING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pipe cutting apparatus, and more particularly, to a pipe cutting apparatus capable of cutting a pipe easily and quickly and increasing cutting efficiency.

Generally, pipes are produced in batches at a certain length in a production plant, but because of various uses, various types of pipes are used in terms of their specifications and materials. In the case of a pipe for drainage, a long pipe may be connected to the pipe, but it is necessary to cut a pipe having a long length and use it if necessary.

Many pipe cutting apparatuses have been devised according to such industrial needs. Conventionally, when cutting a pipe in a radial direction, a method of cutting a fixed pipe in a radial direction by using a general saw machine has been used .

However, in the conventional method, when the pipe to be cut is a thin and light material, there is a fear that the pipe material is deformed when fixed for cutting, and the time required for pipe cutting is long.

Fig. 1 is a front view of a pipe cutting apparatus according to an embodiment of the present invention, Fig. 2 is a plan view of the pipe cutting apparatus shown in Fig. 1, Fig. 3 is a cross- Fig.

Referring to FIG. 2, the pipe cutting apparatus of the present invention mainly includes a pipe transfer assembly 100 for transferring a pipe, a pipe position adjusting assembly (not shown) for determining a cutting position of the pipe, A mounting support assembly 300 and a pipe assembly rotating assembly 400, and a pipe cutting assembly 500 for cutting the pipe.

Figures 1 and 2 show an overall view of a pipe cutting apparatus, with reference mainly to the overall system of Figure 2, with reference to Figure 3, where necessary, of the individual components, if any, .

First, the pipe transfer assembly 100 includes a frame 10 formed to be horizontally long enough to support the length of the pipe, and a plurality of feed rollers 121 to 126 spaced apart from each other at an upper portion of the frame 10, A plurality of conveying cylinders 101 to 105 provided between the conveying rollers 121 to 126 on the frame 10 and an hourglass shaped support roller 112 provided on the end of the conveying cylinders 101 to 105, (111 to 115).

Here, the feed rollers 121 to 126 are connected to the motor to move the pipe to be cut in the horizontal direction, and the pipe moved through the feed rollers 121 to 126 is fed to the feed cylinders 101 to 105 And is supported by support rollers 111 to 115 which are raised or lowered by the support rollers.

Therefore, it is preferable that a plurality of support rollers 111 to 115 provided at the ends of the conveying cylinders 101 to 105 are installed in the form of idle rollers.

Next, the pipe positioning assembly (not shown) includes a sensor for grasping the moving position of the pipe located on the pipe conveying assembly 100, and a driving unit for driving the conveying rollers 121 to 126 As shown in FIG.

Specifically, the process of conveying a pipe according to an embodiment of the present invention will be described as follows. When the pipe mounted on the pipe conveying assembly 100 is horizontally conveyed by the conveying rollers 121 to 126, the movement position of the pipe is sensed by the sensor. If the transported pipe is positioned at one end of the pipe transport assembly 100, the control unit stops driving the transport rollers 121 to 126 by a signal input from the sensor. At this time, the pipes are raised by a height equal to the height of the support rods 101 to 105 for cutting the pipes, the support rollers 111 to 115 are supported by the lower portions of the raised pipes, When the pipe is rotated through the pipe assembly rotation assembly, the support rollers 111 to 115 are supported stably.

Next, the pipe assembly rotating assembly 400 includes a support installed adjacent to the pipe transfer assembly 100, a second motor installed on the support, and a lower roller connected to the power of the second motor and driven to rotate 411, 412).

Here, the pair of lower rollers 411 and 412 horizontally provided on the supporter are in contact with the outer peripheral surface of the pipe conveyed to one end of the pipe conveyance assembly 100, and rotate the pipe through the driving force of the second motor .

Meanwhile, the drive control unit (not shown) for controlling the driving of the second motor can adjust the rotation number of the lower rollers 411 and 412 according to the radius of the pipe located at the end of the pipe mount rotation assembly 400.

For example, when the radius of the pipe is equal to the radius of the lower rollers 411 and 412, the lower rollers 411 and 412 are controlled to make one rotation, and when the radius of the pipe is twice the radius of the lower rollers 411 and 412, Can be controlled to make two rotations.

Next, the pipe mounting support assembly 300 serves to support the pipe together with the pipe mounting rotary assembly 400, and more specifically, to the upper part of the pipe mounting rotary assembly 400, (Not shown) disposed between the upper rollers 321 and 322 and the stationary cylinder 310, and upper and lower rollers 321 and 322 installed at the ends of the stationary cylinder 310, And a pressure sensor (not shown) provided at an end of the first and second pressure sensors 321 and 322.

The upper rollers 321 and 322 descend in the same manner as the downward movement of the stationary cylinder 310 to support the upper portion of the pipe after contacting the upper peripheral surface of the pipe, And the pressure sensor (not shown) senses the pressure applied to the outer circumferential surface of the pipe as the upper rollers 321 and 322 descend.

Next, the pipe cutting assembly 500 includes a cutting saw portion 520 and a cutting transfer portion 510.

The cutting saw blade unit 520 serves to cut a pipe supported through the pipe mounting support assembly 300 and the pipe mount rotation assembly 400 and more specifically to a saw blade rotating unit 500 connected to the saw blade rotating shaft 522, A saw blade body 521 for fixing and supporting the cutting saw blade 523 and a transfer body 511 connected to the cutting transfer part 510 to fix and support the saw blade body 521.

A servo motor and a ball screw may be further provided between the saw blade body 521 and the transfer body 511 to control the saw blade body 523 to be movable in the left and right direction.

The cutting transfer part 510 is connected to the cutting saw part 520 to horizontally move the cutting saw part 520 and includes a cutting cylinder 512 movable in the horizontal direction.

3, the process of cutting a pipe by the pipe mounting rotary assembly 400, the pipe mounting support assembly 300, and the pipe cutting assembly 500 will be described as follows.

When the pipe is transported to one end of the pipe transfer assembly 100 by the pipe transfer process described above, the upper rollers 321 and 322 are lowered by the stationary cylinder 310 to contact the upper peripheral surface of the pipe, , The pressure applied to the pipe is sensed by a pressure sensor (not shown).

When the sensed pressure reaches a predetermined pressure, the lowering operation of the upper rollers 321 and 322 by the mounting cylinder 310 is stopped, and the upper rollers 321 and 322 are fixed in a state supporting the upper portion of the contacted pipe And the lower rollers 411 and 412 connected to the power of the second motor rotate the pipe.

At this time, after the cutting saw blade 520 moves in either direction from the feed cylinder 512 to contact the side surface of the pipe, the cutting saw blade 523 included in the cutting saw blade 520 rotates The pipe is cut.

Although the lower rollers 411 and 412 are described as rotating in the step of fixing the pipe, the operation order may be changed so that the lower rollers 411 and 412 rotate in the step of cutting the fixed pipe.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
