This utility model relates to a non-stop severing device for the production of tubes and other shaped sections. The utility model belongs to the material processing machinery, which comprises mountings, bearings, gears, revolving axles, cutting tools, radial adjusting devices, and angle adjusting devices etc. The utility model is characterized in that: the transverse sections of shaped sections to be severed determine that the edged cutting tools are fixed on the rotation axes and rotate along. The axial line of the rotation axes forms an angle with the moving direction of the shaped sections ranging from 70 degree to 110 degree. The cutting tools fulfill the severing task in the process of rotation with the rotation axes and complete the non-stop fixed-length severing of tubes and other shaped sections. The device has the advantage of low cost, simple operation, high productivity, little deformation of the tubes and shaped sections, which is particularly suitable for the severing of sections in the assembly lines of ornamentation pipes, capillary tubes, condensation tubes with plastic pipes, stainless pipes, copper pipes, band pipes, thick wall pipes, square pipes, rectangular pipes, elliptical pipes in the production thereof.
