Inner cutting type numerical control cutting machine tool for hollow pipes

Abstract

The invention discloses an inner cutting type numerical control cutting machine tool for hollow pipes. The structure of the machine tool comprises a numerical control milling lathe body, an inner cutting type device, an upper hydraulic cylinder, an upper clamping device, the hollow pipes, a linear transmission device, a lower clamping device and a lower hydraulic cylinder. The upper hydraulic cylinder is vertically connected to the inner top face of the numerical control milling lathe body. Compared with the prior art, the machine tool has the beneficial effects that the hollow pipes can be clamped and cut conveniently, meanwhile, the machine tool can adapt to clamping of the hollow pipes with different opening diameter sizes, is wide in application range, and can cut the hollow pipes in asegmented manner, after cutting is finished, the inner cutting type device can push out the cut hollow pipes under the drive effect of the linear transmission device, in the cutting process, cut scraps can be effectively prevented from splashing everywhere, the situation that the cut scraps harm operators is avoided, the high safety supportability is achieved for the operators, meanwhile, multiple cutting wheels cut the hollow pipes synchronously, the cutting area is increased, the cutting efficiency is improved, and cutting time is shortened.

Description

technical field [0001] The invention relates to the technical field of numerical control milling machines, in particular to a numerical control cutting machine tool for internal cutting of hollow tubes. Background technique [0002] CNC machine tools are one of the most widely used machine tools at present. Unlike traditional machine tools, CNC machine tools can perform more precise processing operations. CNC cutting machine tools are widely used in segmental cutting of hollow tubes. [0003] Existing cutting machine tools cut hollow pipes from the outside to the inside, which will cause cutting chips to splash around during cutting, and the cutting chips are extremely sharp, which may cause harm to the operator. In addition, using a single The cutting wheel cuts the hollow tube, that is, the contact surface between the cutting wheel and the hollow tube is small, the cutting efficiency is low, and the cutting time is long. Contents of the invention [0004] The main purpo...
