Abstract

The invention relates to a special combined fixture for machining the upper end face and the lower end face of a round mold crystallizer copper tube and a use method of the special combined fixture. The fixture comprises an installation bottom plate, a first set of upper and lower clamping plates, a second set of upper and lower clamping plates and a positioning plate. The installation bottom plate is used for arranging the fixture on a machine tool or a worktable. The first set of upper and lower clamping plates are vertically arranged at one end of the installation bottom plate, the second set of upper and lower clamping plates are vertically arranged at the other end of the installation bottom plate, the upper clamping plates correspond to the lower clamping plates from the upper portion, and preset shapes are formed between the upper clamping plates and the lower clamping plates so that the copper tube to be machined can be positioned and fixed. The positioning plate is arranged on the machine tool or the worktable and used for positioning the installation bottom plate. By means of the fixture, the standard of upper end face and lower end face machining of the copper tube difficult to precisely position is ingeniously transferred to the fixture, and precise installation and positioning of the copper tube are guaranteed through the specially designed structure of the fixture. Accordingly, errors caused by a lineation method or a simple backer are avoided, it is guaranteed that machined parts are precise and reliable, product quality is improved, and defective products are reduced.

Description

technical field [0001] The invention relates to a crystallizer copper tube for metallurgical continuous steel casting, in particular to a processing and manufacturing technology for an arc-shaped round billet crystallizer copper tube. Background technique [0002] Mold copper tube is a key component in metallurgical continuous steel casting production equipment. According to the shape of the billet cross-section, mold copper tube can be divided into square billet, round billet, rectangular billet and other types. Among them, the arc-shaped round billet mold copper Tube is one of the most widely used types at present. Since the mold copper tube is in a particularly important position in the continuous casting machine, its processing and manufacturing precision requirements are particularly high. [0003] The arc-shaped round billet mold copper tube is characterized in that the transverse section of the mold copper tube cavity is circular and the longitudinal axis line along ...
