[0002] The pipe end forming machine is a highly efficient pipe processing equipment. During the processing of chamfering, flanging, shrinking and expanding the pipe fittings, the cut batches of pipe fittings need to be placed in the pipe section forming machine one by one in an orderly manner. The existing pipe end forming machine uses the weight of the pipe fittings and starts the clamping assembly to arrange the pipe fittings along the inclined surface for orderly feeding.

However, in order to ensure the consistency of the length of the pipe cutting and the neatness of the pipe mouth, the cutting knife needs to be oiled, and the oil applied will adhere to the surface of the pipe. When the material is cut on the inclined surface of the support frame, the oil between the pipes reduces the friction between each other, and often deflection or jamming occurs with the working vibration of the pipe end forming machine. Moreover, when there is a lot of oil attached to the surface, it will also affect the clamping effect of the pipe end forming process on the pipe. Summary of the invention
