DEVICE FOR EXTRUDE SHAPING CROSS-LINKED POLYETHYLENE PIPE

摘要

PURPOSE: A device is provided to increase a compressed administration distance of a piston and to improve a required liner structure for increasing a productivity for over twice than a traditional device. CONSTITUTION: A device for extrude shaping a cross-linked polyethylene pipe is formed by: an integral typed adapter(3) with 15 ¯ 20 millimeters for an inner circumference and 80 ¯ 150 millimeters for a length; a torpedo(1) containing a spider leg for supporting oneself in plural areas in a ring shaped flowing passage; a piston(11) with over 20 millimeters for a compressed administration distance and 16 ¯ 20 millimeters for an outer circumference; a liner(2) with 30 ¯ 40 millimeters for a height and 16 ¯ 20 millimeters for an inner circumference for containing a resource inputting aperture in the center; a mandrel(7) with 600 ¯ 800 millimeters for a length; and a die(6) with 600 ¯ 800 millimeters for a length for containing a ring shaped projected unit being projected in a certain location of the inner circumference toward a central shaft direction of the die for 1 ¯ 3 millimeters. If a cross-linked pipe is extruded, an extruding productivity is increased for over 100 % while improving the exterior and the function of the manufactured pipe by using the presented device.
