DISPOSITIF POUR REALISER DES PERCEES PAR FORMAGE PAR EXPLOSION

摘要

The invention relates to the explosive forming of rim holes and necked holes in sheets and tubes. The aim of the invention is to reduce the manufacturing outlay for punched holes and necked holes and to save energy. The object of the invention is to provide a device for producing rim holes and necked holes using explosive forming. The essence of the invention consists in that a shape store, in which a punch is secured, is arranged in a device for producing rim holes and necked holes. A stemming device is used to accommodate the energy transmission medium and the explosive charge. The punch in the shape store is arranged in such a way that it is situated at a distance from the workpiece wall which is 0 to 10 % of the radius of the rim hole or necked hole. The area of application of the invention is in forming technology, specifically the production of rim holes and necked holes in sheets and tubes. <IMAGE>
