Numerical control cutting machine tool suitable for thin-wall pipeline

Abstract

The invention belongs to the technical field of numerical control cutting machine tools, and discloses a numerical control cutting machine tool suitable for a thin-wall pipeline, the numerical control cutting machine tool comprises a large rotary table and a small rotary table which can rotate, the small rotary table is eccentrically mounted on one side of the large rotary table through a rotary shaft, and two mounting rods are symmetrically fixed on the small rotary table; one mounting rod is coaxially matched with the large rotary table; two sets of positioning cutting assemblies are arranged between the two mounting rods, the two sets of positioning cutting assemblies are matched with the inner side and the outer side of the thin-wall pipeline correspondingly, and telescopic limiting pieces are connected between the two sets of positioning cutting assemblies and the two mounting rods correspondingly; in conclusion, rotation of one positioning and cutting assembly and revolution of the other positioning and cutting assembly can be achieved through rotation of the large rotary table, and therefore circumferential cutting can be conveniently completed when the thin-wall pipeline is fixed; and the positions of the two sets of positioning and cutting assemblies can be symmetrically switched through rotation of the small rotary table, so that the cut thin-wall pipeline is conveniently guided out while feeding is conducted, and efficient and continuous cutting is achieved.

Description

technical field [0001] The invention belongs to the technical field of numerical control cutting machine tools, and in particular relates to a numerical control cutting machine tool suitable for thin-walled pipes. Background technique [0002] In the process of cutting thin-walled pipes (with a wall thickness of 0.3-0.6mm), the cutting blade is arranged on the outside of the thin-walled pipe, and the rotation of the thin-walled pipe itself or the rotation of the cutting blade is used to achieve circumferential cutting, and when cutting Since the cutting blade will squeeze the thin-walled pipe to a certain extent, it will cause deformation at the incision of the thin-walled pipe. [0003] In view of the above problems, patent CN105965081B discloses a thin-walled tube cutting device that can be cut both internally and externally. Based on the principle disclosed in the patent, it can be known that the specific cutting is based on the rotation of the thin-walled tube itself. T...

[0002] In the cutting process of thin-walled pipes (with a wall thickness of 0.3-0.6mm), the cutting blade is arranged on the outside of the thin-walled pipe, and the rotation of the thin-walled pipe itself or the rotation of the cutting blade is used to achieve circumferential cutting, while cutting Since the cutting blade will squeeze the thin-walled pipe to a certain extent, it will cause deformation at the incision of the thin-walled pipe

[0003] In view of the above problems, the patent CN105965081B discloses a thin-walled pipe cutting equipment that can be cut internally and externally. Based on the principle disclosed in this patent, it can be known that the specific cutting is based on the rotation of the thin-walled pipe itself. This method is only suitable for cutting short and small-diameter pipes, but it cannot quickly realize continuous cutting of long or large-diameter pipes
