The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is small. Welded pipe can play different roles in construction sites and construction sites. Therefore, in order to facilitate the use of welded pipes, it is sometimes necessary to bend the welded pipes to meet the use requirements of the welded pipes. When bending the welded pipes, bending equipment will be used.
[0003] According to the search, the Chinese patent document, authorization announcement number CN212070050U, discloses a pipe bending device that is easy to adjust and quickly disassemble and assemble. The device can make the transmission of the welding pipe by the device more automated by setting a first drive frame, a second drive frame, a drive motor, a drive disk, a rotating rod and a fixed column. The use of a bending motor, a vertical rod, a bending disk and an output rod can make the bending operation of the device more convenient. The use of a vertical plate, a fixed screw, a through hole and a fixed nut can make it more convenient for the user to change the transmission size of the equipment. However, the clamping roller and the driven rod in the device are fixed assembly designs, that is, the clamping roller cannot be replaced, and the distance between the two clamping rollers is predetermined and cannot be adjusted, which makes the device unable to adapt to the bending of welding pipes with larger diameters. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
