PURPOSE: A bending machine for fabricating steel door is provided which is used to first bend upper and lower heming construction parts composing front and rear plates in a skirt shape in fabricating a non-welding type steel door. CONSTITUTION: In fabricating a non-welding type steel door in which front and rear plates are reciprocally assembled and fixed with spaced apart from each other by inserting and pressing two channels into upper and lower heming parts respectively, the bending machine for fabricating steel door comprises a main frame(100); two bending units(200) which are oppositely installed on the main frame with spaced apart from each other and bend upper and lower heming construction parts of a steel sheet(11') in a skirt shape by hydraulic pressure; a table(300) which is installed on the main frame between the two bending units to support the steel sheet to be bended; a hydraulic pump(400) which is installed at the main frame to provide each of the bending units with hydraulic pressure; and a controller(500) for controlling operation of the bending units, wherein each of the bending unit comprises a base(210), a die block(230), an ascending and descending cylinder(250), an ascending and descending plate, a pressing plate and a punch block(240), and at least any one bending unit(200) comprises an installation position adjusting means comprising a transfer screw(263), a bush, two guide rails(261) and two guide blocks(262).
