Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, specifically a machine tool for processing the inner cavity of a crystallizer copper tube. Background Technology

[0002] The crystallizer copper tube is one of the accessories of the casting machine. The traditional crystallizer copper tube generally includes a copper tube and a cooling jacket. The cooling jacket is fitted on the outside of the copper tube, and a cooling channel is set between the cooling jacket and the copper tube. Coolant is passed into the cooling channel to cool the copper tube. The inner cavity of the crystallizer copper tube needs to be finely machined during processing.

[0003] However, traditional crystallizer copper tube processing machine tools often use clamping plates on both sides to fix the copper tube in place when limiting and fixing the copper tube. The clamping plates are not compatible with the shape of the copper tube, resulting in poor fixing effect and a large risk of copper tube displacement during processing. Utility Model Content
