Abstract

The invention relates to the processing of metals by pressure, in particular, to machines for the production of articles from tubular billets, and can be used in the manufacture of process piping for oil-producing equipment. The purpose of the invention is to improve the quality of products and expand technological capabilities. The machine contains an angled forming tool 21, a clamp 6 of the workpiece 12, made in the form of a hollow cylinder with longitudinal strips on the inner surface, made with slopes equal in magnitude and opposite in direction. The slats are installed in contact with the sleeve, which serves to place the workpiece 12. During operation, the heated end of the workpiece 12 comes into contact with the working surface 22 of the tool 21 and is reduced, 5 sludge.
