The present application belongs to the technical field of rubber
pipe cutting processing, and discloses a rubber
pipe cutting machine, which comprises a cutter rotating frame and clamping mechanisms symmetrically matched on both sides of the cutter rotating frame; the clamping mechanisms comprise a negative suction sleeve capable of penetrating the rubber
pipe, a guide sleeve coaxially matched with the outside of the negative suction sleeve, and a negative suction generator, and the negative suction generator is located at the outer end of the guide sleeve in the axial direction; the cutter rotating frame is coaxially sleeved on the outside of the guide sleeve, and a
cutting cutter is connected to the cutter rotating frame through an extension piece; the cutting cutter comprises a cutter seat and a cutting cutter disc rotatably installed in the cutter seat; the inner end of the guide sleeve is provided with a spiral guide groove, and the outside of the cutter seat is fixedly provided with a sliding rod slidingly extending into the spiral guide groove. In summary, the present application adopts the negative suction fixation and spiral centripetal cutting mode to reduce the
radial deformation of the rubber pipe during actual cutting, thereby effectively improving the flatness of the rubber pipe cutting end face.
