Abstract

DC60 (13/10/43) In the rolling method, dimensions are made by installing at least three sets of a four-roller rolling mill as a set, the central corner at 1-eye of the section that forms the full circle of each extrusion roller. The ball in the first path was arranged to be less than 15 degrees, the center corner theta 3 was arranged to be at least 45 degrees in the third path, and the center theta 2 angle was at least 30 degrees in the second path B groove of each rolling roller. The ball was arranged in such a way that it was avoided. It consists of a tangent line formed by a part that forms a full circle. A guide roller with four guide rollers is installed on the inlet side of the second path. And the free surface of the workpiece is Captured and guided by a guide roller, the angle of each roller's V-groove is aligned with the same angle (90 degrees + theta 1) between the straight line that forms the escape section of the closest rolling roller in the first path. This technology Even wire diameters of 7.0 mm or less, excellent surface properties can be achieved while maintaining a large free range (larqe size free ranqe) in the extrusion method. At least three sets of a four-roller compactor in a series, the center corner thread 1 of the full circle section of each rolling roller in the first path is classified as less than 15 ํ. At least 45 in the third path and the center corner theta 2 is arranged as at least 30 in the second path B. The grooves of each roller are arranged so that the sidewalls It consists of a tangent line formed by a part that forms a full circle. A guide roller with four guide rollers is installed on the inlet side of the second path. And the free surface of the workpiece is Captured and directed by guide rollers, the angle of each roller's V-groove is aligned like an angle (90 ํ + thread 1) between the straight line that forms the escape section of the closest rolling roller in the first path. This technology Even with a diameter of 7.0mm or less, excellent surface properties can occur while maintaining a large free range (larqe size free ranqe).
