The invention relates to an oil filling iron pipe forming device and forming process. The oil filling iron pipe forming device comprises an end extrusion device, a straight pipe weld detection device,a bending device, a flaring device, a flaring weld detection device and a chamfering device. The end extrusion device is used for extruding an oil outlet of an oil filling iron pipe to form corrugations so that the oil outlet can be assembled to a hose conveniently. The straight pipe weld detection device is used for conducting weld detection on a straight pipe machined through the end extrusiondevice, a weld seam of the straight pipe serve as a top surface and is prevented from being located on the side of stress concentration in the bending process, and defective products are avoided. A bent pipe bent by the bending device is transported to the flaring device through a manipulator, and then the flaring device conducts flaring machining on an oil inlet. The flared part is subjected to weld detection and then is
