The present invention relates to the field of metal cutting technology, specifically to a metal capillary forming and processing equipment, including a base plate, an auxiliary mechanism and a cutting mechanism. In this case, the two support plates cooperate with the lower pressure plate 1 to achieve the fixed limit of multiple metal capillaries at the same time, and then the corresponding metal capillaries are penetrated by the support column, and the cutting section is pressed down and limited by the lower pressure plate 2 at the same time. The cooperation between the lower pressure plate 2 and the support column improves the stability of the cutting tool on the metal capillary, and avoids the problem of bending deformation of the metal capillary caused by cutting. In the present invention, the metal capillary is moved a specified distance each time for loading through the cooperation between the positioning group and the transmission group. After the cutting is completed, the metal capillary that has been cut is pushed out by the pushing group, which simplifies the processing steps of the metal capillary and improves the processing efficiency of the metal capillary cutting.
