[0027] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0028] See also Figure 1-Figure 4 The utility model provides a multi-station pipe bending machine, including a pipe bending device 001, a limiting device 002 and a supporting device 003.

[0029] The pipe bending device 001 includes a first column 100, and a first groove 110 for limiting the position of the steel pipe is provided on the rod body of the first column 100. The first groove 110 is provided so that a plurality of steel pipes can be placed on the rod body of each first groove 110, and the first groove 110 cooperates with the second groove 251 to support the steel pipe. A connecting rod 120 for supporting the first groove 110 is fixedly installed at the lower end of the first column 100.

[0030] A turntable 130 is fixedly installed at the lower end of the connecting rod 120 for cooperating with the limiting device 002 to control the rotation of the first column 100. The turntable 130 is located inside the cavity of the operating cavity 210. A rotating shaft 131 is fixedly installed in the middle of the turntable 130 for cooperating with the supporting box 200 to support and limit the turntable 130. The rotating shaft 131 is hinged in the hole cavity of the limiting hole 211 to facilitate the rotating shaft 131 to drive the turntable 130 to rotate, so that the first groove 110 revolves around the rotating shaft 131 as the rotating axis. The outer wall of the turntable 130 is fixedly installed with worm gear teeth 132 for cooperating with the worm 220 to control the synchronous rotation of multiple turntables 130. The worm gear teeth 132 and the worm 220 are meshed, so that when the worm 220 rotates, it synchronously drives the turntable 130 to rotate, so that the turntable 130 drives the first column 100 to revolve under the limitation of the rotating shaft 131, and cooperates with the second column 250 to bend the steel pipe.

[0031] A limiting device 002 is installed at the lower end of the pipe bending device 001 for cooperating with the pipe bending device 001 to bend multiple groups of steel pipes. The limiting device 002 includes a support box 200 for supporting and limiting the turntable 130. An operating cavity 210 is opened inside the support box 200, and the turntable 130 is arranged in the cavity of the operating cavity 210.

[0032] The inner cavity of the operating cavity 210 is provided with a limiting hole 211 for limiting the rotating shaft 131. When the worm 220 cooperates with the worm gear 132 to drive the rotating disk 130 to rotate, the rotating disk 130 drives the rotating shaft 131 to rotate in the cavity of the limiting hole 211. The operating cavity 210 is equipped with a worm 220 for controlling the rotation of multiple rotating disks 130. The worm 220 is tilted in the cavity of the operating cavity 210 to facilitate the control of the rotation of multiple rotating disks 130. The inner cavity of the operating cavity 210 is installed with a limit block 221 for limiting the worm 220. The limit blocks 221 are arranged at both ends of the worm 220. The front end of the worm 220 is fixedly installed with a motor 222 for controlling the rotation of the worm 220, so that after starting, the motor 222 drives the worm 220 to rotate, so that the worm 220 cooperates with the worm wheel teeth 132 to drive the turntable 130 to rotate, and the turntable 130 drives the first groove 110 to revolve, so that the first groove 110 cooperates with the second column 250 to bend multiple groups of steel pipes synchronously.

[0033] A support plate 230 for supporting the motor 222 is fixedly installed at the front end of the support box 200. An arc-shaped slide groove 240 for the connecting rod 120 to slide is provided at the upper end of the support box 200. When the turntable 130 drives the first column 100 to revolve around the rotating shaft 131, the connecting rod 120 is synchronously driven to rotate in the groove cavity of the arc-shaped slide groove 240. A second column 250 for cooperating with the first column 100 to bend the steel pipe is fixedly installed at the upper end of the support box 200. When the first column 100 revolves around the rotating shaft 131, the first column 100 revolves around the second column 250 synchronously. The middle of the second column 250 is provided with a second groove 251 for limiting the steel pipe. The second groove 251 cooperates with the first groove 110 to limit the steel pipe synchronously, so that one side of the steel pipe is in the groove cavity of the second groove 251, and the other side of the steel pipe is in the groove cavity of the first groove 110. The second groove 251 cooperates with the first groove 110 to support the steel pipe together. The first column 100 cooperates with the second column 250 to divide the steel pipe into multiple columns. The second column 250 is 1 / 4 of the distance from the support box 200. The distance between the left wall gradually increases, so that the distance between the first row of second columns 250 and the left wall of the support box 200 is smaller than the distance between the second row of second columns 250 and the left wall of the support box 200, and the distance between the second row of second columns 250 and the left wall of the support box 200 is smaller than the distance between the third row of second columns 250 and the left wall of the support box 200, and so on. This makes it easier for the steel pipes to avoid collision when they are bent, and the distance between adjacent second columns 250 can also be increased to avoid collision of the steel pipes when they are bent.

[0034] A supporting device 003 for supporting and limiting the limiting device 002 is fixedly installed at the lower end of the limiting device 002. The supporting device 003 includes a supporting platform 300 for supporting the limiting device 002. Support legs 320 for supporting the supporting platform 300 are fixedly installed at the lower end of the supporting platform 300. A third column 310 for limiting the steel pipe is fixedly installed at the upper end of the supporting platform 300. A third groove 311 for further limiting the steel pipe is opened in the middle of the rod body of the third column 310. The third groove 311 cooperates with the second groove 251 and the first groove 110 to support the steel pipe. Every two rows of third columns 310 support one row of steel pipes, and each row of steel pipes is a group. Multiple rows of third columns 310 are arranged on the upper end of the supporting platform 300 for synchronously bending multiple groups of steel pipes to increase bending efficiency.
