The present invention relates to a bending device of a rotor housing. The invention comprises: a base jig which has a housing part with one open part penetrating a stove pipe hole on the floor of the housing part; a press jig which forms a bending part on the wings, encountering a circumference of the base jig by having parts of the plate of the rotor housing, and wings pressed and inserted into the housing part; and a supporter installed in the stove pipe hole in a moveable position in an upward and downward direction, and moved with the plate while supporting the wings applied to the bending part to prevent a poor quality of unfill wings except the bending part. Unlike an existing technology, the present invention can either prevent or minimize the poor quality of unfill parts other than the bending parts, by maintaining a width and a thickness of the bending part by back pressuring the lower part of the bent part when bend-forming the rotor housing. |
