s4, switching a bending wheel: automatically switching the bending wheel with the required radius according to the set radius and bending length, and adjusting the center position of the bending wheel and the center position of the auxiliary bending;
s5, bending: the auxiliary bending adopts an inclined slide block, so that the pressing position can be automatically adjusted, a certain pressing force is maintained, and the automatic bending is realized.
