PURPOSE: A bellows pressing device is provided to reduce defects by inserting a mandrel so as to maintain the horizontality of bellows and uniformly compress bellows. CONSTITUTION: A bellows pressing device comprises a fixed and a movable jaw(10,20) and a mandrel(100). The fixed and the movable jaw are formed on both upper sides of a die. The movable jaw compresses a bellows(2) while longitudinally operating along a guide unit(35) by using a pressing cylinder(30). The mandrel is horizontally installed at the inner center between the fixed and the movable jaw. The mandrel is moved forward and backward by a working cylinder(110).
