Referring to FIG. 1, a flange forming apparatus 1000 according to an embodiment of the present invention includes a clamping portion 2000 and an angle portion 3000.

According to the present embodiment, the clamping part 2000 can be rotated about the angle part 3000 with the flange 10 fixed, and the flange 10 can be fixed to the angled part 3000, The iron insert 710 can be engaged with the side portion 14 of the flange 10 by using the punching portion 600 so that the steering angle with respect to the flange 10 can be performed more easily and precisely.

Hereinafter, the configuration of the flange steering apparatus 1000 according to the present embodiment will be described in detail with reference to FIGS. 1 to 5. FIG.

The clamping portion 2000 can rotate the flange 10 in a compressed state. That is, the flange 10 can be rotated by the rotation unit 300, which will be described later, while being fixed by the clamping unit 2000. For reference, the rotary unit 300 may include a rotary shaft 320 and a rotary drive unit (not shown) for rotating the rotary shaft 320.

The clamping part 2000 according to the present embodiment may include a flange supporting part 100, a first pressing part 200, and a rotation part 300.

The flange support 100 may provide a mounting surface for supporting the flange 10 prior to squeezing the flange 10 using a first compression portion 200 as described below, as shown in Fig.

The flange support 110 may have a "U" -shaped cross-section as viewed from the side of FIG. Accordingly, the circular flange 10 can be mounted on the "U" -shaped flange support 110.

At this time, the flange 10 may be separated from the pipe. Therefore, the flange 10 can be more easily mounted on the flange supporting portion 100 of the clamping portion 2000. [

A first pressing portion 200 to be described later may be disposed on one side of the flange supporting portion 100 and a rotating shaft 320 of the rotating portion 300 is fixedly coupled to the other side of the flange supporting portion 100. The rotary shaft 320 may be rotatably supported by the fixture 500. [

In addition, a protrusion 110 may be formed on the inside of the flange supporting portion 100. The protrusion 110 may be, for example, a rod shape. The flange 10 can be supported on the protrusion 110 by placing the central opening 12 of the flange 10 over the protrusion 110 as shown in Fig.

When the flange 10 is small enough not to be supported by the flange support 100, the flange 10 may be supported by the protrusion 110.

The first pressing portion 200 includes a clamping roller 210 for pressing the side portion 14 of the flange 10 and a pressing driving portion 220 for moving the clamping roller 210 in the radial direction of the flange 10 .

As shown in FIG. 3, the clamping roller 210 may be rotatably coupled to a moving member 224, which will be described later. In this embodiment, as shown in FIG. 3, two clamping rollers 210 may be installed on one shifting member 224. The shifting member 224 provided with the pair of clamping rollers 210 may be disposed on both sides of the flange (10 in Fig. 1), respectively, and as shown in Figs. 4 and 5, Can be moved toward the side portion 14 of the flange 10 or in the opposite direction by the stretching and relaxing operation of the driving portion of the flange 10.

As described above, when the moving member 224 to which the pair of clamping rollers 210 are coupled is disposed on both sides of the flange 10, the flange 10, which is initially mounted on the flange supporting portion 100, The center axis of the rotary shaft 320 can be aligned with the center of the rotary shaft 320 of the rotary unit 300.

That is, in the state where the flange 10 is initially mounted on the flange supporting portion 100, the center axis of the flange 10 may be inconsistent with the center of the rotation shaft 320 of the rotation portion 300. However, A pair of clamping rollers 210 are disposed on both sides of the flange 10 (i.e., a total of four clamping rollers 210 press the side portions 14 of the flange 10) The center axis of the flange 10 can be automatically aligned with the center of the rotating shaft 320 in the process of pressing the clamping roller 210 to the side 14 of the flange 10 using the clamping roller 220. [

The pressing driving unit 220 is a device for moving the clamping roller 210 in the radial direction of the flange 10 and may include a guide member 222, a moving member 224, a driving unit, and a link member 226.

Specifically, the guide member 222 is capable of movably supporting the clamping roller 210 so that the clamping roller 210 can move in the radial direction of the flange 10.

In the case of this embodiment, the guide member 222 may be a plate extending in the radial direction of the flange 10. In this case, the guide member 222 may be provided with a guide hole 222a extending along the longitudinal direction thereof.

The guide hole 222a can provide a movement path of the moving member 224 connected to the clamping roller 210. [

Referring to FIG. 2, a plurality of guide holes 222a may be arranged along the longitudinal direction of the guide member 222. As shown in FIG. According to the present embodiment, the guide member 222 may be formed with two guide holes 222a parallel to each other. In this case, the moving member 224, which will be described later, can stably move along the guide hole 222a while supporting the clamping roller 210. [

4, the guide member 222 may be formed with a center shaft 222b protruding therefrom. The center shaft 222b may be connected to the first link 226a of the link member 226 to be described later.

The moving member 224 is rotatably coupled to the clamping roller 210 as shown in FIG. The moving member 224 slides along the guide hole 222a formed in the guide member 222 and guides the movement of the clamping roller 210 as shown in Figs.

3, the moving member 224 according to the present embodiment includes a support 224a to which the clamping roller 210 is rotatably coupled, and a guide hole 222a rotatably coupled to the support 224a. And a guide roller 224b that moves along the guide roller 224b.

The shifting member 224 may be formed by projecting a link shaft 224c parallel to the center axis of the clamping roller 210. [ The link shaft 224c may be connected to the second link 226b of the link member 226 to be described later.

As described above, the moving member 224 moves along the guide hole 222a while supporting the clamping roller 210, so that the clamping roller 210 can be moved to the side portion 14 of the flange 10.

The moving member 224 is moved along the guide hole 222a by receiving driving force from the driving unit. The driving force of the driving portion is transmitted to the moving member 224 by the link member 226.

4 and 5, the link member 226 may include a first link 226a and a second link 226b.

The first link 226a is a bar-shaped member, and the center portion thereof is rotatably coupled to the center shaft 222b of the guide member 222 and can rotate about the center shaft 222b.

The second link 226b is a bar-shaped member, one end of which is rotatably coupled to the end of the first link 226a and the other end of which is rotatably coupled to the moving member 224. [ Specifically, the other end of the second link 226b may be rotatably coupled to a link shaft 224c provided on the movable member 224. [

According to this embodiment, as shown in Figs. 4 and 5, the first link 226a rotates about the center shaft 222b of the guide member 222, so that the second link 226b is rotated about the center shaft 222b of the guide member 222, The movable member 224 can be moved while rotating around the end of the movable member 226a. At this time, the moving member 224 can move the clamping roller 210 while moving linearly reciprocating along the guide hole 222a.

Therefore, the clamping roller 210 can be moved to the side portion 14 of the flange 10 or in the opposite direction through a process in which the link member 226 and the moving member 224 operate in an interlocked manner.

The driving portion provides a driving force so that the link member 226 and the moving member 224 cooperatively operate.

Specifically, the driving unit according to the present embodiment may include a cylinder 225. The cylinder 225 may be, for example, a pneumatic or hydraulic cylinder.

In this case, one end of the cylinder 225 may be rotatably coupled to a portion where the first link 226a and the second link 226b are coupled, as shown in FIG. The other end of the cylinder 225 may be rotatably coupled to the guide member 222.

4, the extension driving force of the cylinder 225 is transmitted to the shifting member 224 through the link member 226, and the shifting member 224 is engaged with the flange 10 from the sides 14 thereof.

5, the compression driving force of the cylinder 225 is transmitted to the shifting member 224 via the link member 226 so that the shifting member 224 is moved to the position shown in Fig. 10 toward the side 14 of the body.

Although the present invention is not limited to this configuration, the first link 226a may be provided on the center shaft of the guide member 222, And can be transformed into various types of driving parts if they can rotate about the center line 222b.

For example, the driving unit may include a motor that rotates the first link 226a about the center shaft 222b of the guide member 222. [ In this case, the motor can rotate the first link 226a around the center shaft 222b while being fixed to the guide member 222. [

Alternatively, although not shown, the crimping driver 220 may be coupled to the clamping roller 210 by, for example, one end coupled to the clamping roller 210 and the other end coupled to the support member 310 or the guide member 222, And may include a pneumatic or hydraulic cylinder that moves in the radial direction of the flange 10.

Meanwhile, the clamping part 2000 according to the present embodiment may further include a second pressing part 400.

Referring to FIGS. 1 and 2, the second pressing part 400 may include a pressing plate 410 and a driving part 420.

The compression plate 410 may be a plate disposed opposite the side of the flange 10 as shown in FIG.

As shown in Fig. 1, the compression plate 410 can move forward or backward relative to the side surface of the flange 10, thereby pressing the side surface of the flange 10 in the state supported by the flange support 100, So that the flange 10 can be more stably fixed.

The flange 10 can be more stably fixed regardless of the thickness of the side portion 14 of the flange 10 because the compression plate 410 can be moved back and forth with respect to the side surface of the flange 10.

The driving unit 420 causes the compression plate 410 to move back and forth with respect to the side surface of the flange 10. As the driving unit 420, for example, a hydraulic or pneumatic cylinder may be used. In addition, a linear actuator may be used as the driving unit 420, for example.

On the other hand, the first pressing part 200 is rotated by the rotating part 300 with the flange (10 in Fig. 1) fixed. The rotation unit 300 may include a support member 310 for supporting the first pressing unit 200 and a rotation driving unit (not shown) for rotating the support member 310 about the center axis of the flange 10.

Referring to FIG. 2, the support member 310 may be formed in a shape corresponding to the guide member 222 of the first press portion 200. One side of the support member 310 can be coupled to the guide member 222 of the first press portion 200. The support member 310 and the guide member 222 may be spaced apart to allow the flange 10 to be inserted therebetween. The flange support 100 may be disposed between the support member 310 and the guide member 222.

Referring to FIG. 1, a rotating shaft 320 may be formed on the other side of the supporting member 310 (FIG. 2), and the rotating shaft 320 may be rotatably coupled to the fixing body 500.

In this case, a rotation driving unit (not shown) may be installed in the fixing body 500 and may be connected to the rotating shaft 320 to rotate the rotating shaft 320 to rotate the flange supporting unit 100 and / The first pressing portion (200 in Fig. 2) can be rotated.
