DEVICE FOR EXPLOSIVE FORMING POLYGONAL PIPES

摘要

A device for explosive forming consists of a housing which houses a die matrix with a workpiece, a transfer medium and a cord explosive charge. The die consists of six trapezoidal prisms, one of which is displaced by a screw mounted in the housing in the die cavity. Inside the space formed by six trapezoidal prisms removable triangular prisms are located in two opposite corners. In addition on the cord charge cylindrical explosive charges are located at a distance not less than their length.
