Problems solved by technology

Although the upper punch, the die and also the lower punch are usually accessible (i.e. grippable), since the mandrel is usually arranged in the lower or lowermost plane which is in most cases inaccessible to the manipulator , so changing the mandrel is difficult, especially since the mandrel additionally extends into the lower punch or is arranged coaxially with the lower punch, making its removal even more difficult

Embodiment Construction

[0031] now refer to figure 1 , shows a schematic perspective view of the powder forming press together with the assembly for coupling the mandrel to the lower punch, correspondingly the tray carrying the lower punch is shown in partial section. Since universal powder molding presses are generally known, only the most important components or a few elements relevant to the invention are detailed below.

[0032] The powder molding press 1 comprises an upper plate 2 , a mold plate 3 , a lower plate 4 and a seat plate 5 in a top-down view. The plates are connected to each other by a not-detailed forming press frame. Typically, one of the plates (eg die plate 3 ) is fixedly connected to a given forming press frame, while the other plate is vertically mobile.

[0033]The upper punch 7 is fixedly connected to the upper plate 2 by a first chuck "upper punch chuck 8", and the die 10 is fixedly connected to the die plate 3 by a second chuck "die chuck 11". The lower punch 12 is fixed...

Abstract

The invention relates to a powder press assembly. The assembly comprises a coupling for direct or indirect coupling the core rod (15) to the lower punch (12) of a powder press. The coupling is configured as a magnetic coupling and comprising two coupling elements (20, 30), the first (20) of which is actively connected to the core rod (15) and the second (30) of which is actively connected to the lower punch (12). The magnetic coupling comprises several permanent magnets (24a, 24b, 33a, 33b) arranged at each coupling element. These permanent magnets (24a, 24b, 33a, 33b) are arranged and adapted to each other such that when coupling the two coupling elements (20, 30) the first coupling element (20) is automatically rotated by the effect of the field lines of the magnets (24a, 24b, 33a, 33b) into a predetermined angular position relative to the second coupling element (30).

Description

technical field [0001] The invention relates to a powder forming press assembly comprising at least one lower punch and a mandrel. A powder forming press of the type referred to in this context is generally characterized by, in addition to the stated lower punch and mandrel, an upper punch and a die arranged between them as a forming tool. The mandrel is used to provide recesses or openings in the press-formed part (compact). Background technique [0002] When a powder forming press is required to produce parts of different shapes, then it is often the case that the upper punch, die, lower punch and also the mandrel all have to be replaced. This replacement is currently performed automatically, for example by means of a robotic arm. Although the upper punch, the die and also the lower punch are usually accessible (i.e. grippable), since the mandrel is usually arranged in the lower or lowermost plane which is in most cases inaccessible to the manipulator In this case, chan...
