Embodiment Construction

[0036] as by figure 1 As seen, the ceramic and / or metal powder extruder 1 comprises a frame 2 in which various other components are housed. The other parts are partly fixedly connected to the frame 2 and partly adjustable relative to the frame and relative to each other, in particular in the extrusion direction.

[0037] A constituent part of the core is the die 3 , into whose die bore one or more punches 4 , 5 are immersed, especially from below. In particular above the dies 4 , 5 the die bores can be filled with the extrusion mass 6 . One or more further dies 7 can be inserted from above into the die hole filled with the extruded mass 6 for deforming the extruded mass 6 into an extruded body. The extrusion mass 6 is in particular a metallic and / or ceramic powdery and / or granular raw material.

[0038] By way of example only one upper punch 7 engages with its underside on a particularly plate-shaped tool holder 8 . By means of an electric drive 10 , which in particular ha...

Abstract

The invention relates to a method for controlling a ceramic and / or metal powder extruder (1) for pressing an extruded mass (6), in which method at least one electric drive (15, 16; 20 , 21), the driving device adjusts at least one die (5; 4) along the extrusion direction, so that the driving device (15, 16; 20, 21) moves the die (5; 4) along the position theoretical trajectory (as1) ), and the drive is readjusted when deviating from the theoretical position trajectory (as1), wherein as at least one adjustment parameter for the readjustment is used the measured forces (F11, F12), which act on the pressing mass (6 ), the die (4) or the part carrying the die (17-19). The invention also relates to a ceramic and / or metal powder extruder (1) designed to carry out the method.

Description

technical field [0001] The invention relates to a method for controlling a ceramic and / or metal powder extruder for pressing extruded substances, in which method at least one electric drive is controlled in such a way that it adjusts at least A die, the drive means moves the die along a theoretical positional trajectory to each instantaneous theoretical position of the die, and the drive means readjusts when it deviates from the theoretical positional trajectory. The invention also relates to such controlled ceramic and / or metal powder extruders for pressing extruded masses. Background technique [0002] There are ceramic and / or metal powder extruders in which during the extrusion process the individual axes, ie in particular the die and the part carrying the die, need to be floated during the forming process. Floating means that the shaft is pushed out of its position by at least one other, in particular opposite, shaft. However, the axis is pressed against the axis by th...
