[0032] Step 2: manually hang a material corresponding to the model into a predetermined area on the material input roller group 11, and then start the machine.

[0033] Step three, the power cylinder 14.3 of the straightening rod transmission mechanism 14 automatically drives each pair of side-pushing straightening rods 12 to translate symmetrically to the vertical plane of the longitudinal axis of the equipment unit according to the program instructions, and the power cylinder 14.3 automatically locks the material after it is centered; at the same time, the cutting bracket 2 automatically moves vertically according to the program instructions so that the axis line of the circular hole of the turntable wheel seat 2.3 coincides with the cross-sectional geometric center line of the material; at the same time, the side support rod transmission mechanism 23 in the workpiece output roller area is automatically driven by the transmission gear group 25 and the shaft transmission motor reducer 26 according to the program instructions, so that each pair of side support rods 21 translate symmetrically to the vertical plane of the longitudinal axis of the equipment unit, and automatically stops when the symmetrical spacing is in a position suitable for the workpiece width guide and is slightly wider than the workpiece width.
