Abstract
Изобретение относитс к обработке металлов давлением и может быть использовано при раздаче труб. Цель изобретени - повышение качества обрабатываемых труб за счет обеспечени увеличени точности размеров готовых изделий. Инструмент содержит пуансон, т гу с конической оправкой и хвостовиком, а также втулку, снабженную регулируемым упором, выполненным в виде двух гаек, и установленную на т ге пластинчатую пружину, контактирующую с пуансоном. Пластинчата пружина при рабочем перемещении т ги упираетс в торец трубы и разжимает пуансон на оправке до наружного диаметра, превышающего исходный диаметр трубы. 1 з.п. ф-лы, 4 ил.The invention relates to the processing of metals by pressure and can be used in the distribution of pipes. The purpose of the invention is to improve the quality of the processed pipes by providing an increase in the dimensional accuracy of the finished products. The tool contains a punch, a rod with a conical mandrel and a shank, as well as a sleeve, equipped with an adjustable stop made in the form of two nuts, and a lamellar spring mounted on the rod that is in contact with the punch. When operating, the plate spring rests against the end of the pipe and expands the punch on the mandrel to an outer diameter exceeding the original diameter of the pipe. 1 hp f-ly, 4 ill.
