Device and method for calibrating a sintered moulded part

Method for calibrating a sintered moulded part (2) with an angular toothing (3) by means of a calibrating tool (4), comprising a lower punch (15) with a lower punch external toothing (23), a vertically movable and axially rotatably mounted upper punch (8) with an upper punch external toothing (21), as well as an axially rotatably mounted die (14) with a die internal toothing (24), according to which the sintered moulded part (2) is placed onto the lower punch (15) and positioned on the latter, then the upper punch (8) is lowered in the direction of the sintered moulded part (2), and in this way the sintered moulded part (2) and the lower punch (15) are lowered in the direction of the die (14), and thereby the angular toothing (3) of the sintered moulded part (2) is pressed into the die internal toothing (24), wherein the lower punch (15) is moved only in vertical direction and the direction of movement of the lower punch (15) is reversed after reaching a lower end position and the calibrated sintered moulded part (2) is moved by the vertical movement of the lower punch (15) upwards out of engagement with the die internal toothing (24) of the die (14).
