step five: starting a second motor (31) to drive the bending roll (30) to rotate, and simultaneously extending the telescopic rod (32) to drive the bending roll (30) to move towards one side close to the pipe;
step six: the bending roller (30) applies pressure to the right end of the pipe, so that the pipe is bent towards one side close to the second limiting roller (26);
step seven: removing the bent pipe;
step eight: and repeating the process from the first step to the seventh step until all the pipes are bent.
