Device for influencing the volume flow of extruded plastically deformable material

摘要

In the device for influencing the volume flow of extruded plastically deformable material, this is conveyed to an outlet nozzle in the additive manufacturing of components. It is a flange (1) which is arranged between an extrusion unit and an outlet nozzle (3) and connected to the extrusion unit and the outlet nozzle (3). A channel (10) formed in the flange (1) is formed from the extrusion unit to the outlet nozzle (3). A piston (2) is rotatably mounted in the flange (1) perpendicular to the longitudinal axis of the channel (10) and is guided through the channel (10). A bore (8) is formed in the piston (2), which opens into a bypass channel (9) which leads to a bypass nozzle (5). At least one groove (2.1) is formed in the area of the channel (10) on the outer circumferential surface of the piston (2) such that material (6) through the groove (2.1) in the direction of the outlet nozzle (1) depending on the angular positions of the piston (1) 3) and / or through the bore (8) from the bypass nozzle (5).
