Crystallizer copper pipe inner cavity machine tool

Abstract

The invention provides a crystallizer copper pipe inner cavity machine tool. The crystallizer copper pipe inner cavity machine tool comprises a machine tool body which is placed on a horizontal working face, the upper end of the machine tool body is provided with a longitudinal slideway, a lower slide seat is arranged on the longitudinal slideway, and thus, the lower slide seat can move longitudinally under driving of a longitudinal feeding mechanism; the lower slide seat is provided with a transverse slideway, the transverse slideway is provided with an upper slide seat, and thus, the upper slide seat can move in the transverse direction under driving of a transverse feeding mechanism; the upper slide seat is provided with a workbench, and the workbench is provided with an indexing system; the indexing system comprises an indexing mechanism, an upper opening chuck and a lower opening chuck, and the upper opening chuck and the lower opening chuck are oppositely arranged and cooperate to clamp a copper pipe; and the side edge of the machine tool body is provided with a vertical column, the vertical column is provided with a vertical slideway, the vertical slideway is provided with acutter bar box, and thus, the cutter bar box can be driven by a vertical feeding mechanism to move in the vertical direction. The machine tool has the advantages of being capable of conducting clamping conveniently, good in rigidity, high in precision and the like, and the problems that a single or small batch of copper pipe inner cavities are long in machining cycle, low in precision and the like are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing and processing, in particular to a special machine tool for processing inner cavities of copper tubes of crystallizers, which is suitable for processing inner cavities of copper tubes of square, rectangular and round tubular molds. Background technique [0002] The continuous casting mold is called the "heart" of the continuous casting machine, and the copper tube is the most important part in the mold. During the continuous casting process, the copper pipe not only contacts with the high-temperature molten steel, but also constantly rubs against the solidified billet shell, which is easily damaged, so the repair of the copper pipe is extremely important. [0003] With continuous casting industry's continuous improvement of billet quality and passing steel requirements, single-taper or double-taper copper pipes can no longer meet the demand, multi-taper or continuous taper can ada...

AI Technical Summary

Problems solved by technology

The explosion method can obtain copper tubes with high precision, but the cost is relatively expensive and the domestic technology is not yet mature; the extrusion method mainly relies on the mandrel mold, and the manufacture of the mandrel mold takes a long time and the extrusion method is not easy to obtain high-precision copper tubes. Copper tube: Machining needs to design a special machine tool, the processing cycle is short and the precision is high, there is no need to customize the mandrel mold for a certain type of copper tube, and the versatility is wide

[0005] At present, the processing of the inner cavity of the copper tube of the crystallizer cannot be completed by ordinary CNC machine tools or machining centers. It is necessary to design a special machine tool. The existing special machine tools include two methods of profiling and numerical control system to ensure the accuracy of the inner cavity of the copper tube.

For the former, copper tubes with different inner cavity tapers need different profiles, and customized profiles will increase the processing cycle of copper tubes, so it is difficult to achieve efficient processing of single-piece small-batch copper tubes

Controlling the size of the inner cavity through the numerical control system has good versatility and higher promotion value, but the existing machine tools of this type have the problem of low machine rigidity
