Embodiment Construction

[0020] The press according to the invention has a press frame 10 with an upper holding plate 12 and a lower holding plate 14 . The upper holding plate 12 and the lower holding plate 14 are connected to each other and to a load bearing arranged approximately centrally between the upper holding plate 12 and the lower holding plate 14 via four vertically extending spacers 16 in the illustrated embodiment. 18 is connected. In the exemplary embodiment shown, the carrier part 18 is designed in one piece and has a U-shaped contour lying in a horizontal plane, ie, the plane of arrangement or extension. The lower holding plate 14 rests on the ground via four legs 20 . The press according to the invention also has a modular tool guide unit, which has an upper die unit, which can include an upper die plate 22 with a Shown upper die; Lower die unit, described lower die unit can comprise lower die plate 24, and described lower die plate has lower die not shown; And be arranged on upper d...

Abstract

A press for producing a pellet from powdered material, comprising a press frame with an upper and a lower retaining plate, which are connected to one another by several vertical spacers and with at least one supporting element, which is disposed between the upper and the lower retaining plate, a tool guiding unit with at least one upper punch unit with at least one upper press punch and / or at least one lower punch unit with at least one lower press punch and with a die assembly with at least one holder for powdered material, which is to be pressed by the upper and / or lower press punch, wherein the tool guiding unit is disposed at the supporting element, and at least one upper drive unit for moving the upper punch unit in the vertical direction and / or at least one lower drive unit for moving the lower punch unit and or the die assembly in the vertical direction, wherein, when the press is operating, the upper drive unit and / or the lower drive unit are supported at the supporting element in such a manner, that the reaction forces, which are produced during the pressing of the powdered material in the at least one holder, are generated as action forces, are passed into the supporting element.

Description

technical field [0001] The invention relates to a press for producing compacts from powdery materials, for example metal powder or ceramic powder. Powdered material is filled into the forming receptacle of the tool unit and then pressed into the forming receptacle, for example by means of an upper punch and a lower die, to form a pressed part. Background technique [0002] Such a press is known, for example, from EP2311587A1. This known press has a press frame with a press upper part and a press lower part and vertical struts which connect the press upper part and the press lower part to one another. For the pressing results achieved with such a press and for the wear of the press, it is very important that all components which are in the force-transmitting flow during the pressing process be aligned as precisely as possible. In the known press, a large number of components, usually produced individually, and a plurality of component planes are present in the force transmi...
