Abstract

The utility model provides a fully automatic C-shaped pipe port sealing machine, which belongs to the technical field of pipe bending machines. It solves the problems that the pipe end of the C-shaped pipe bent by the existing pipe bending machine always has a section that is not in an arc shape, and when the pipe end of the C-shaped pipe needs to be sealed, it can only be welded and polished by adding an additional cover disc, which is inefficient and has poor aesthetics. The utility model first bends the two ends of the pipe material, and the bending force arm is longer, which is more labor-saving. The two ends are bent first by the front pipe bending mechanism. After the first bending and cutting are completed, the two arc-shaped bent pipes at the head and tail of the front and rear pipe materials can be made at the same time, and then the two arc-shaped bent pipe ports on a pipe material are sealed by the pipe mouth sealing mechanism. Finally, the middle part of the pipe material is bent by the rear pipe bending mechanism to form a C-shaped main pipe. The utility model has a high degree of automation and greatly improves production efficiency.
