A forging machine includes a first tool carrier and a second tool carrier, a drive system for driving the first tool carrier in a working movement, a machine frame, wherein the machine frame is formed of a concrete prestressed with prestressing elements, wherein the machine frame comprises a frame base and a frame support connected to the frame base, wherein longitudinal prestressing elements are provided which extend parallel to the central axis (M) and each extend through the frame support, the frame base, and through the cross-member, wherein transverse prestressing elements are provided both in the frame base and in the cross-member, wherein the longitudinal prestressing elements and the transverse prestressing elements include prestressing anchors, and wherein the prestressing anchors are each arranged on an outer surface of the frame base or the cross-member.

The invention relates to a tool for realising a press quenching and tempering method for a rotational symmetric tool, in particular for a gear wheel, wherein the tool is at least in part manufactured as an additive and wherein, in an additively manufactured area of the tool, is formed at least one pipe for guiding a fluid.

Press tools and particularly crimp tools having a C-frame tool head are described which are configured such that upon a typical use load, the C-frame head deflects to a position in which mating components or surfaces are aligned. Also described are C-frame heads that utilize a particular deflection compensating engagement connection between a piston and a ram die holder. In addition, various methods of compensating for deflection are described. The use of such configurations, engagement connections, and methods enables such tools to be formed from lighter weight materials and/or to incorporate weight optimization designs.

A kit for forming a forge table and a forge pot for use therewith to carry a fuel for combustion so as to generate heat for heating a metallic workpiece. The forge table includes a tabletop with a central opening for receiving the forge pot. The forge pot includes a container for supporting the fuel and an air chamber fluidically communicated with the container and including an opening for fluidic communication with an external airflow source which generates an airflow for subsequent conveyance to the container for combusting the fuel. Each kit comprises interconnectable components made from rigid non-combustible sheet material. The airflow source is mounted in fluidic communication with the chamber and there is provided an intermediary valve component supported on the same mounting pegs carrying the source that is movably supported on the pegs so as to be operable to control passage of the airflow to the chamber.

A system of a separable frame for presses and press frames (1), the respective press frame (1) comprising uprights (2) and a head piece as an upper cross connection (3) and a press table as a lower cross connection (4), which as structural units form a closed frame that absorbs static and dynamic forces for any required functions of a press such as the drive of a ram used for forming with tools. The uprights (2) are attachable laterally or longitudinally to the cross connections (3, 4) by non-positive or non-positive and positive joining geometries (5) and releasable connector (5.1). The proposed press frames (1) have a reduced vertical deflection (v2) compared to press frames joined by tie rod bracing (6).

The invention relates to an apparatus for material forming, by means of a tool (41) and a drive unit (2), the apparatus being arranged to move the drive unit (2) to provide kinetic energy to the tool (41), for the tool (41) to strike a work material (W), so as to form the work material (W), the apparatus being provided with an impact head (4″) between the drive unit (2) and the tool (41), and the apparatus being arranged to provide the kinetic energy to the tool by the drive unit (2) striking the impact head (4″), wherein at least a region of the impact head (4″) is allowed to move in relation to the tool (41) laterally to a direction of the stroke of the drive unit, whereby the impact head is arranged to expand laterally in relation to the tool. The invention also relates to a method for material forming.
