Cutting apparatus for stainless steel thin-wall bend pipe

The utility model provides a cutting apparatus for a stainless steel thin-wall bend pipe. The cutting apparatus comprises a cutting blade, a clamping round disc, a pedestal, an index plate and clamping devices, wherein the cutting blade is arranged on a cutting machine; the bend pipe is mounted on the clamping round disc; the round disc is connected with the pedestal; the round disc is mounted on the index plate; rotation angles of the bend pipe can be timely controlled via adjustments of the index plate angle; and the round disc is equipped with two clamping devices respectively clamping a bend pipes with a pipe diameter of 65mm and a bend pipe with a pipe diameter of 52mm. Stainless steel thin-wall bend pipes with different pipe diameters can be mechanically cut by the cutting apparatus, so part profile deformation and surface damage caused by manual cutting can be greatly reduced; and beneficial effects of stable forming quality, product profile and surface quality improvement as well as cutting efficiency
