CN223531545U - A mandrel cutting device for bending pipes - Google Patents

Abstract

This utility model relates to a mandrel cutting device for bent pipe fittings, including a pipe feeding assembly, a pipe clamping assembly, and a mandrel cutting assembly. The mandrel cutting assembly includes a mandrel cutting longitudinal slide rail, a mandrel cutting longitudinal slide block, a mandrel cutting longitudinal moving cylinder, a mandrel cutting frame plate, a mandrel cutting pressure cylinder, a mandrel cutting pressure plate, a mandrel cutting upper pressure slice, and a mandrel cutting lower top slice. The bent pipe fitting is fed to the front end of the pipe clamping assembly and clamped by the pipe feeding assembly. The mandrel cutting longitudinal moving cylinder drives the mandrel cutting longitudinal slide block to move toward the bent pipe fitting. The mandrel cutting pressure cylinder drives the mandrel cutting frame plate upward, causing the mandrel cutting pressure plate to press downward under the hinged connection with the mandrel cutting frame plate. The upper pressure slice also presses downward in conjunction with the lower pressure slice, thus cutting off the excess mandrel portion at the end of the bent pipe fitting. This results in less overall vibration and less deformation of the mandrel cutting surface, effectively improving the mandrel cutting quality.
