The three-dimensional bending device of the pipe.

For the sake of understanding, we will define two-dimensional bending and three-dimensional bending.

Secondary bending refers to bending a pipe or the like in one direction on a plane (for example, XY plane), and three-dimensional bending refers to a two-dimensional bent pipe or the like that does not coincide with a Z bending plane (for example, XY plane) It means to bend in either direction on the plane (XY plane) and (YZ plane).

Conventionally, in bending a pipe that is welded and fixed to a chamber such as a compressor, a worker inserts a rod into a pipe of a chamber and manually bends the pipe three-dimensionally so that not only the work efficiency is lowered, but also the desired shape of the pipe. There were various problems such as not being able to bend.

Referring to the effect of the three-dimensional bending device of the pipe according to the present invention configured as described above are as follows.

First, when the chamber 18 to which the pipe 19 to be bent is welded in the solid state display state of FIGS. 1 and 2 is supplied to the working position, the cylinder 15 for pipe coupling and separation of the primary bending means is provided. The groove is formed at the tip of the pipe noise bar 20, which is fixedly connected to the clamp 17 and the connector 21 at the tip of the plunger 14 by driving, as shown in FIGS. The pipe 19 is inserted and joined to 20a.

In this case, since the clamp 17 is linearly guided by the linear motion guide 16, the pipe noise bar 20 fixed thereto is accurately approached toward the pipe 19.

When the pipe 19 is coupled to the pipe noise bar 20 as described above, the rotary actuator 3 is driven to rotate the Z-axis driving shaft 2 at a predetermined angle, and the driving gear fixed to the Z-axis driving shaft 2 ( 4) is rotated, the driven gear (11) engaged with the drive gear (4) is rotated about the Z-axis rotation axis (6) and is fixedly coupled to the Z-axis rotation axis (6) with the driven gear (11) The rotating plate 12 rotates in a counterclockwise direction, whereby the bracket 13 coupled to the rotating plate 12 rotates in a counterclockwise direction about the Z axis rotating shaft 6.

As shown in FIG. 7 and FIG. 8, the primary ben of the pipe 19 inserted into and coupled to the tip groove 20a of the pipe noise bar 20. This will be written.

Here, the primary bending is made in a certain direction on the X-Y plane.

After the first bending is completed, the secondary bending cylinder 31 constituting the second bending means is driven so that the plunger 30 moves forward, and thus the rack 33 fixedly connected to the tip of the plunger 30 is driven.
