An underwater cutting system for an extruding machine is provided to minimize an economic loss according to a maintenance of a machinery by remarkably reducing a changing cost of a cutter. In an underwater cutting system for an extruding machine, a housing(12) has a spring(11) connecting with an inner part of an axis support part and a groove formed toward an axial direction. A bolt is connected to the axis support part to joint with the groove of the housing. A seat has an arc type of a contact surface located at the inner part of the housing. A ring type of a groove is formed at a front side of the seat and is connected by a front end of the housing and four joint grooves. A bushing forms the joint groove connected with a ball. A ball is fixed with a nut jointing a screw into a screw bar. An arc type of a contact face is formed at a rear end of a joint axis coping with the arc type of the contact face of the seat. And, a fin is fixed to a joint axis for locating at the ring type of groove formed at the inner part of the housing. |
