Round tube and square tube mixed tube making machine

The invention relates to a round tube and square tube mixed tube making machine. The problems that in the prior art, synchronous pipe manufacturing of round pipes and square pipes is difficult to achieve through pipe manufacturing equipment, and the pipe manufacturing efficiency is low are solved. The device comprises a two-dimensional unreeling device, a steel plate leveling structure is arranged at one end of the two-dimensional unreeling device, the steel plate leveling structure is connected with a pipe body forming device through a transition conveying table, a sizing assembly is arranged on one side of the pipe body forming device, a pipe body fine adjustment mechanism is arranged between the sizing assembly and the pipe body forming device, and a pipe body cutting device is arranged at one end of the sizing assembly. And the segmented pipe body is conveyed to the pipe pushing device through the conveying roller way frame and is conveyed to the outside through the pipe pushing device. The pipe making ma
