Description

Technical Field

[0002] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern mechanical processing industry; double-end elbows include a straight pipe section and two elbow sections symmetrically arranged at both ends of the straight pipe section. During the production process of this type of pipe fittings, the elbow margins at both ends need to be cut by a cutting machine so that the length of the elbows at both ends meets the requirements of the drawings and ensures that the two ends are parallel;

[0003] When some existing cutting machines cut double-ended elbows, they can only process one end of the elbow at a time. After cutting one end, the pipe needs to be removed and rotated before processing the other end. This easily causes the two ends to be non-parallel and the work efficiency is low. Therefore, a double-ended elbow cutting machine is proposed. Utility Model Content
