Abstract

An object of the present invention is to provide a helical bending pipe processing apparatus capable of bending an extremely thick steel pipe. A cylinder 1 having a spiral plate 8 wound around an outer periphery thereof at a predetermined pitch is rotatably mounted via a drive device, and a bent pipe attaching / detaching tool projecting from the outer periphery of the cylinder 1 is provided. 3, after inserting one end side of the bent tube 5 and fixing it with the jack bolt 7, the bent tube pressing adjustment tool 4 arranged with a gap on the outside of the cylinder 1 is moved by the slide shaft 4 a. After adjusting up or down, the cylinder 1 around which the spiral plate 8 is wound is rotated by the driving device, and the bent tube pressing adjustment tool 4 arranged at intervals outside the cylinder 1 is bent. The pressing force of the processing tube 5 can be adjusted. Furthermore, since the bent pipe 5 is naturally pressed by the spiral bent pipe pressing adjustment tool 4, when the cylinder 1 around which the spiral plate 8 is wound rotates, the bent pipe adjusting tool 4 rotates. The roller 4b also rotated at the same time, and a spiral bent tube was completed. [Selection] Figure 1

Description

The present invention relates to a helical bending tube processing apparatus.

Conventionally, this type of helical bending tube apparatus can only bend a pipe with a thin bending tube.

China Utility Model Notice (CN201930997)

Problems that the device tries to solve

The conventional spiral bending pipe processing apparatus is complicated in structure, expensive in machine, and can only bend a pipe with a thin steel pipe thickness, and it has been desired to provide a spiral bending pipe processing apparatus that can bend an extremely thick steel pipe. .

Means to solve the problem

In order to solve the above problems, the present invention provides a cylinder or column in which a plate is spirally wound at a predetermined pitch on the outer periphery, a drive device that rotationally drives the cylinder or column, and the cylinder or column. A bent pipe attaching / detaching tool that is fixed to the outer periphery and grips one end side of the bent pipe, and a bent pipe pressing adjustment tool that is arranged with an interval outside the cylinder or column. As the bending bending pipe processing device, the bent pipe pressing adjustment tool can be adjusted up and down, bending the thick steel pipe, which has been a difficult problem, and the ovalization of the steel pipe has been eliminated. .

Effect of device

The helical bending tube processing apparatus according to the present invention includes a bending pipe holding guide arranged at intervals parallel to the axis of a cylinder or a cylinder, and a pressing guide for the processing pipe as well as the rotation axis of the helical bending spindle. By rotating it, the ovalization rate of the bent tube was made as small as possible. Furthermore, by operating the presser guide of the bent pipe up and down, the diameter of the bent pipe can be adjusted differently, and the ellipticity of the bent pipe can be adjusted. Moreover, the conventional spiral bending apparatus can only bend a pipe with a thin steel pipe thickness, but the helical bending apparatus can bend a thick steel pipe and an extra-thick steel pipe. In addition, the bending time is short, and the helical pitch and the accuracy of the perfect circle of the helical steel pipe are improved, so that the elliptical bending of the helical bending pipe can be reduced.

It is a front view of the spiral bending pipe processing apparatus which shows one Example which concerns on this invention. It is the top view which looked at FIG. 1 from the upper part. It is detail explanatory drawing of the attachment / detachment tool which hold | grips the one end side of the bending process pipe | tube of FIG.

Form for carrying out the invention

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

1 to 3 show an embodiment according to the present invention. In this embodiment, a cylinder 1 having a spiral plate 8 wound around an outer peripheral portion at a predetermined pitch is mounted via a drive device 2 so as to be rotationally driven. At the same time, one end side of the bent tube 5 is inserted into the bent tube attaching / detaching tool 3 projecting from the outer peripheral portion of the cylinder 1 and fixed with the jack bolt 7. After adjusting the bent pipe pressing adjustment tool 4 provided and arranged with the slide shaft 4 a up or down, the cylinder 1 around which the spiral plate 8 is wound is rotated by the driving device 2, so that the outside of the cylinder 1 is rotated. The bent tube pressing adjustment tool 4 arranged with a gap can adjust the pressing force of the bent tube 5. Furthermore, since the bent pipe 5 is naturally pressed by the spiral bent pipe pressing adjustment tool 4, when the cylinder 1 around which the spiral plate 8 is wound rotates, the bent pipe adjusting tool 4 rotates. The roller 4b also rotated at the same time, and a spiral bending tube (not shown) was completed. In the present embodiment, the cylinder 1 around which the spiral plate 8 is wound is used, but a column may be used.

The present invention can be used in the industry for manufacturing boilers, heat exchangers, etc. as a helical bending tube processing device. Moreover, it can also be used for greenhouse cultivation etc. which require the spiral bending pipe | tube which heats underground, underwater, etc. with a helical warm pipe.
