step four: starting a third motor (27) to drive the first limit roller (25) and the second limit roller (26) to rotate and move the pipe, so that the right end of the pipe exceeds the right side surfaces of the first limit roller (25) and the second limit roller (26);
step five: starting a second motor (31) to drive the bending roller (30) to rotate, and simultaneously enabling the telescopic rod (32) to stretch to move towards one side close to the pipe along with the bending roller (30);
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 processes from the first step to the seventh step until all the pipes are bent.
