Problems solved by technology

The inner and outer bevels and circular grooves at both ends of the half-chord are usually milled by edge milling machine equipment. Because the parts are super large and semi-circular, the clamping stability on the machine tool is poor when processing the ends, and the two clampings can only Processing one piece, high production cost and low efficiency

Abstract

A half-chord pipe bevel processing method and its equipment are used to process half-chord pipe bevels or similar curved surface bevels on jack-up drilling platforms. Chord tube processing tool, the half-chord tube processing fixture is installed on the workbench of the planer milling machine, the workbench is provided with a clamping groove for the positioning of the half-chord tube processing fixture, the half-chord tube The machining tools include at least two groups of forming tools, which are respectively used to process the bevel plane and the outer fillet groove of the bevel of the half chord. The method includes positioning and clamping, positioning and clamping at least two half chords to be processed in the half chord processing fixture; milling, processing the groove plane and the outer circle on the outside of the half chord respectively with a forming tool Corner groove; exchange processing, exchange the positions of the two half chords, repeat the above steps for the unprocessed part inside the half chord, and then cut the material for inspection and report.

Description

technical field [0001] The invention relates to a machining method and equipment, in particular to a half-chord beveling method and equipment for jack-up drilling platform half-chord beveling or similar curved surface beveling. Background technique [0002] The half-chord of the jack-up drilling platform is made of high-strength steel, and the expanded size of a single half-chord is more than 8 meters * 0.4 meters. The shape of the half chord is pressed through a large hydraulic mold. The inner and outer bevels and circular grooves at both ends of the half-chord are usually milled by edge milling machine equipment. Because the parts are super large and semi-circular, the clamping stability on the machine tool is poor when processing the ends, and the two clampings can only Processing one piece, the production cost is high and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a half-chord be...
