发明名称 Stamping-extrusion process and device
摘要 The subject of the invention is a device and a process for producing single-piece parts, including a bulk section and an elongated section, the device includes a die, formed from at least two half-shells, provided with an orifice for introducing material and bearing as a hollow the shape of the bulk section of the part, at least one of the two half-shells includes an extrusion orifice for producing the elongated section of the part. The process includes a step of pushing a slug of material into a die, provided with an inlet orifice and bearing as a hollow, the shape of the bulk section of the part, and a step of extruding a fraction of the slug to produce the elongated section of the part through an extrusion orifice of the die so as to form a blank of the part via a stamping-extrusion operation.
