Method for processing crystallizer copper pipe with upper and lower installation spigots

Abstract

The invention discloses a method for processing a crystallizer copper pipe with upper and lower installation spigots. The method comprises the specific steps that (1) each side of a copper pipe semi-finished product which is formed through extrusion are respectively reserved with 1-2millimeters as a machining allowance according to the length dimension of a finished product; (2) a mounting plate of a combination fixture is fixed on an operating platform of a numerical control machine tool; (3) the copper pipe is installed and fixed through the combination fixture; (4) a lower end spigot mounting surface, a lower opening end face, an external chamfer and an internal chamfer are machined on the copper pipe; (5) an upper end spigot mounting surface is machined on the copper pipe; and (6) an upper opening end face and an upper opening annular groove are machined on the copper pipe. According to the method, the method which is continuously used by a conventional machining method and takes the external surface of the copper pipe as a basis reference for various machining surfaces is changed, and the surface of an inner cavity of the copper pipe is used as the basis of machining; and moreover, processes are reasonable in arrangement, and tools are appropriately used, so that the machining quality can be ensured.

Description

technical field [0001] The invention relates to a processing and manufacturing technology for a mold copper tube of a continuous casting machine. Background technique [0002] The mold copper tube is the core component of the continuous casting machine, and its manufacturing accuracy and installation accuracy are very high, especially the manufacturing accuracy, which is an important basis for ensuring the installation accuracy. If the deviation of manufacturing accuracy is too large and exceeds the specified requirements, it will have a serious adverse effect on the performance of the continuous casting machine equipment, affect product quality, reduce production efficiency, and even cause abnormal production. [0003] With the development of continuous casting technology, the level of technology has improved rapidly, and the requirements for equipment performance have become higher and higher. The structure and manufacturing process of equipment have been continuously impr...

Problems solved by technology

At present, most of the conventional processing methods are directly processed on the machine tool based on the shape of the copper pipe, or with a small amount of conventional tooling to assist in processing. The arrangement of the processing procedures varies from manufacturer to manufacturer, so the quality varies greatly. The processing quality is difficult to meet the design requirements
