Among pipe connecting method without welding in order to take advantage of pipeline flange is a integrally molded him processing method and apparatus for producing

摘要

The present invention relates to a method for connecting a pipeline without welding and a pipeline connection method using a flange, a gasket, and a clamp, The present invention relates to a method for machining a flange and a method for manufacturing the same, and more particularly, to a pipe-integrated flange machining method in which a steel pipe is inserted, a steel pipe is machined into a flange, The essential function of the main working part, which folds the end of a steel pipe as a working material and processes it into a pipe-integrated flange, is to supply the steel pipe, to fix it while the steel pipe is being formed into the flange, And a steel pipe for discharging the formed steel pipe after the completion of the forming Tube fixing bracket part; A machining head for cold-pressing the end portion of the steel pipe to form a flange to be molded; Can be divided into plural; The constitution of the steel pipe fixing bracket is composed of a shut-off bar (111) for positioning the supplied steel pipe at a predetermined position and for determining the width of the flange at the same time; A first guide rod 110 connected to the shut-off bar, the first guide rod 110 indicating the position of the steel pipe as a measured unit and having a manual work handle; And a first hydraulic cylinder (210) for applying a force to the mold frame (200) so as to fix and support the steel pipe so that the steel pipe does not move back due to the pressing force applied to the steel pipe end during the cold rolling process for the machining process; The construction of the machining head portion for cold-pressing and machining into a flange includes a conical roller 20 for applying a pressing force for rolling; A machining support 10 for allowing the conical roller 20 to be inserted in the center so that the setting position of the conical roller 20 can be changed along the guide path; A second hydraulic cylinder (40) which provides a pressing force to allow the work support (10) to be rolled; An induction furnace (30) for converting linear motion of the second hydraulic cylinder (40) into rotary motion; And a T-shaped guide screw longitudinal axis (50) for maintaining the set travel distance when the machining support (10) slides along the guide path (30).
