The present invention relates to a pipe cutter device, and in particular, the purpose of cutting the pipe of about 6m to the required size at a time to cut the pipe cutter by setting the feed cutter to the length to focus on the faster pipe cutting will be.

Referring to the conventional pipe cutter, as shown in Figs. 3A and 3B, the pipe cutter is provided with a pipe cutter 100 in which three roller-type cutters are installed in a vise form, and a chain type roller is provided for each node. Pipe cutters 200 and the like were used.

However, this means that the pipe is fixed to a separate support and rotated by manual operation to cut it, which requires a separate gold drawing on the pipe to cut to a certain length, and requires a lot of time for cutting work. There was a problem with mass cutting.

Therefore, the present invention has a pair of upper and lower supports on both sides to cut a predetermined length (typically 6 m) of pipes, which are pre-fabricated and supplied in a single operation, or divided into arbitrary sizes in order to solve the above problems. At least two pairs of pipe cutters fixed at the guide position are installed by fixing the H-shaped guide beams as crossbars so that the pipes can be cut by the required number of pipes by manual cutting. It is an object of the present invention to provide a pipe cutting device that allows a simple and rapid operation.

Hereinafter, described in detail by the accompanying drawings as follows.

In constructing the pipe cutter apparatus, as shown in FIGS. 1 and 2, H-shaped guide beams 13A and 13B having a positioning scale 12 above and below the support 11 on both sides are rolled up, In the guide beam 13A, guide rollers 22 guided from the upper and lower sides of the guide beam 13A are arranged inside the c-shaped frame 21, and the lower side of the frame 21 has a roller cutter 23 at the end thereof. The cutting body 2 to which the cylinder 24 is installed is installed to be transported left and right, and at the lower portion of the corresponding position, guide rollers 32 guided from both the upper and lower sides of the H-shaped guide beam 13B inside the c-shaped frame 31. A pair of support rollers 34 are arranged at intervals before and after a plurality of support rollers 34 are arranged at brackets 33 which are installed on both sides of the c-frame 31, and the bottom of the c-shaped frame 31 is fixed and rotated by a motor 4 having a built-in reducer. The interlocking gear 42 meshing with the upper surface of the driving gear 41 is constructed and A support 3 having a pair of driven gears 43 arranged on the bracket 33 on the same axis as the support roller 34 axis to be engaged with the interlocking gear 42 is installed to be moved left and right in the guide beam 13B. On the pipe alignment axis of the one side support, a pneumatic cylinder 14 for pipe alignment is installed.

In the drawings, reference numerals 25 and 35 denote lock fasteners after the point positions of the cutter body 2 and the support 3 are transferred, and 5 denotes a pipe to be cut.

Looking at the operation and effect of the present invention configured as described above, first, by using the graduation 12 displayed in front of the upper and lower guide beams (13A, 13B) in Figure 1 the predetermined length by manual operation or automatic supply from the rear The cutting body 2 and the support 3 are guided in the state in which the fasteners 25 and 35 are loosened so as to be in a position to be cut in an equal or arbitrary division length of the pipe 5 as the fasteners 25 and 35. Fix it.

At this time, the guide is moved along the upper and lower ends of the H-shaped guide beams 13A and 13B by the respective guide rollers 22 and 32.

Subsequently, the pipe 5 having a predetermined length is supplied from the rear of the device of the present invention by manual operation or automatic supply, and its outer diameter is seated on the front and back support rollers 34 of the support 3, before and after the support 11 The pneumatic cylinder 14 on one side is operated to align the reference position of the pressure seated pipe 5.

Subsequently, the pipe 5 seated between the support rollers 34 of the supporter 3 with the roller cutter 23 at the rod end by applying air pressure to the pneumatic cylinder 24 of the cutter body 2 located on the upper surface thereof. Pressurize.

Subsequently, a reduced rotational force by supplying power to the motor 4 rotates the drive gear 41 and rotates the interlocking gear 42 and the driven gear 43 connected thereto, thereby supporting a pair of support rollers 43. ) Is rotated in one direction and at the same time the pipe (5) is rotated and the pipe is pre-set by the roller cutter (23) pressed on the pipe (5) by the action of pressing the pneumatic cylinder 24 of the cutting body (2) It is cut at one time according to the measured dimensions.

The present invention is constructed and operated as described above by cutting a predetermined number of water pipes to a desired dimension by processing a pipe having a predetermined length, and forming a pair of supports and a cutter body in one operation. This is quick.

Therefore, it is a design having features that can greatly reduce the cumbersome work and the resulting work cost by a number of conventional processes.

Claims (3)

In constructing the pipe cutter device, the H-shaped guide beams 13A and 13B having the positioning scales 12 above and below the both sides of the support 11 are rolled up, and the upper guide beam 13A is inside the c-shaped frame 21. At least two or more cutting bodies 2 on which the pneumatic cylinders 24 having roller cutters 23 are placed left and right at the same time as the guide rollers 22 arranged on both sides of the upper and lower sides are laid down. A pair of brackets 33 which are installed to be transported and arranged in the lower guide beam 13B on both sides of the upper and lower sides of the c-shaped frame 31 are laid out, and at the same time, the brackets 33 are placed on both sides of the upper portion of the frame 31. Of the support roller 34 is formed at regular intervals before and after, and at the bottom thereof, an interlocking gear 42 engaged with the upper surface of the drive gear 4 on which the motor 4 with the reduction gear is fixed is rotated. In the same axis as the supporting roller shaft A pair of chukseol the kit driven gear 43, a pipe cutter device of the at least two support 3 engaged with the interlocking gear, characterized to be installed so the left and right feed.
