The invention relates to the technical field of sheet metal part bending, in particular to a combined type bending machine which comprises a rack, a lower die and an upper die are arranged on the rack, and the upper die punches a sheet metal part so that the sheet metal part can form a first bend on the lower die; the upper bending mechanism forms a second bend on the sheet metal part; and the lower bending mechanism forms a third bend on the sheet metal part. The manufacturing method of the M-shaped sheet metal part adopts the composite bending machine, and comprises the following steps: placing the sheet metal part on the lower die, and stamping a first bend on the sheet metal part; the profiling mechanism compresses the sheet metal part on the side surface of the upper die; the upper inclined pressing block forms a second bend on the sheet metal part; and the lower inclined pressing block forms a third bend on the sheet metal part. All bending of the sheet metal parts can be completed only through one-time
