DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a cold-bent steel pipe straightening device includes a base plate 1, characterized in that: a support frame 2 is fixedly connected to the outside of the base plate 1, and the bottom of the inner wall at both ends of the support frame 2 is fixedly connected to the same limit rod 3, and a driving component 6 is installed on the outside of the limit rod 3. The driving component 6 includes two mounting plates 601 slidably mounted on the limit rod 3, and a plurality of driving wheels 602 are rotatably connected to the middle of the two mounting plates 601, and a pulley 603 is coaxially fixed to the outside of the top of the plurality of driving wheels 602, and two adjacent pulleys 603 are sleeved with the same belt 604.

[0025] An extension frame 605 is fixedly connected to the outer walls of the ends of the two mounting plates 601 that are away from each other, and a motor 606 is fixedly installed on the outer walls of the tops of the two extension frames 605. The rotating shafts of the two motors 606 are coaxially fixed to the two pulleys 603 respectively.

[0026] The two mounting plates 601 will move synchronously with the two limit blocks 702, and the multiple driving wheels 602 on the top will also move toward each other. At this time, it is only necessary to start the motor 606 on the top of the extension frame 605. The rotating shaft of the motor 606 can drive the pulley 603 connected to it to rotate. The pulley 603 will drive several other pulleys 603 to rotate synchronously through the belt 604 connected to it, and then the multiple driving wheels 602 will also be driven to rotate at the same time. Driven by the multiple driving wheels 602, the steel pipe can be pulled to move automatically.

[0027] like Figure 2 and Figure 4 As shown, a correction component 7 is installed inside the support frame 2, and the correction component 7 includes a same bidirectional screw 701 that is rotatably connected to the top of the inner walls at both ends of the support frame 2, and a limit block 702 is threadedly connected at both ends of the bidirectional screw 701. The two limit blocks 702 are respectively fixedly connected to the top outer walls of the two mounting plates 601, and a motor 2 703 is fixedly installed on the outer wall of one end of the support frame 2. The rotating shaft of the motor 2 703 and the bidirectional screw 701 are coaxially fixed.

[0028] The relative positions of the two limit blocks 702 are adjusted according to the size of the cold-bent steel pipe. By starting the second motor 703, the bidirectional screw rod 701 is driven to rotate between the support frames 2. The two limit blocks 702 restricted by the limit rod 3 will be driven by the bidirectional screw rod 701 to move toward each other, thereby ensuring that the two limit blocks 702 can just contact the outer wall of the steel pipe. When the steel pipe slides between the two limit blocks 702, the bent part can be corrected.

[0029] like Figure 2 and Figure 3As shown, a cleaning assembly 8 is installed on one side of the top of the two mounting plates 601, and the cleaning assembly 8 includes a cleaning roller 802 rotatably connected to one side of the top outer wall of the mounting plate 601, wherein a driving wheel 602 and the top outer wall of the cleaning roller 802 are coaxially fixed with a transmission wheel 801 and a driven wheel 803, respectively, and the transmission wheel 801 and the driven wheel 803 are sleeved with the same belt 2 804.

[0030] The transmission ratio between the driving wheel 801 and the driven wheel 803 is much greater than one, and one rotation of the driving wheel 801 can drive the driven wheel 803 to rotate multiple times, which is beneficial to improving the cleaning effect.

[0031] When the two pulleys 603 rotate, they will also drive the two connected transmission wheels 801 to rotate. The transmission wheel 801 drives the driven wheel 803 to rotate through the belt 2 804. The driven wheel 803 drives the cleaning roller 802 to rotate on the top of the mounting plate 601. The cleaning roller 802 can clean up the debris generated during the correction process.

[0032] like Figure 1 and Figure 2 As shown, a support plate 5 is fixedly connected to both ends of the top outer wall of the base plate 1, and multiple stabilizing rods 4 are fixedly connected between the two support plates 5. The two mounting plates 601 are slidably mounted on the outside of the two stabilizing rods 4, which can increase the stability of the overall state of the mounting plates 601 and help ensure the driving effect.

[0033] like Figure 3 As shown, the outer walls of the circumferences of the multiple driving wheels 602 are all fixedly covered with rubber anti-skid sleeves, which can increase the friction between the driving wheels 602 and the steel pipes to avoid slipping during the driving process.

[0034] The utility model provides a cold-bent steel pipe correction device, the specific working principle is as follows:

[0035] When the device is working, first adjust the relative position of the two limit blocks 702 according to the size of the cold-bent steel pipe, and drive the bidirectional screw rod 701 to rotate between the support frame 2 by starting the motor 2 703. The two limit blocks 702 restricted by the limit rod 3 will be driven by the bidirectional screw rod 701 to move toward each other, thereby ensuring that the two limit blocks 702 can just contact the outer wall of the steel pipe. When the steel pipe slides between the two limit blocks 702, the bent part can be corrected, and the two mounting plates 601 will move synchronously with the two limit blocks 702, and the multiple driving wheels 602 on the top will also move toward each other. At this time, you only need to start the motor 1 606 on the top of the extension frame 605, and the motor 1 606 on the top of the extension frame 605 will start. The rotating shaft of machine 606 can drive the pulley 1 603 connected to it to rotate, and the pulley 1 603 will drive several other pulleys 603 to rotate synchronously through the belt 1 604 connected to it, and then multiple driving wheels 602 will also be driven to rotate at the same time. Driven by multiple driving wheels 602, the steel pipe can be pulled to move automatically, and the two relatively two pulleys 603 will also drive the two connected transmission wheels 801 to rotate when rotating. The transmission wheel 801 drives the driven wheel 803 to rotate through the belt 2 804, and the driven wheel 803 drives the cleaning roller 802 to rotate on the top of the mounting plate 601, and the cleaning roller 802 can clean up the debris generated during the correction process.
