A forging head for additive manufacturing, comprising a base portion and a forging portion. The forging portion extends from the base portion for forging a cladding layer during formation of the cladding layer by additive manufacturing. The forging head further comprising a through hole which is formed through the base portion and the forging portion, for at least one of an energy bean and an additive material to pass through during formation of the cladding layer.

A draw press includes a carriage moveable toward a work piece and an upper die movably secured to the carriage. The upper die is movable with respect to the carriage to draw the work piece. A method for drawing a metal part is also disclosed.

A press forming system includes a press working unit, a material supply device, a detection device, and a control device. The press working unit includes a slide that moves in accordance with an operation pattern in which the slide passes through an advance position where press forming is formed from a withdrawal position, and returns to the withdrawal position. The material supply device starts a supply operation at a synchronous timing before the slide returns from the advance position to the withdrawal position. The control device performs a control for stopping the slide before the slide reaches the withdrawal position from the advance position in a case where the suppliable state of the forming material is not detected within a predetermined determination period by the detection device.

A method for hot forming of a cast forging ingot uses a forging device with radially guided forging dies of which each have two die parts, which can be radially moved relative to each other and of which the inner die part bearing a forging tool is drive-connected, using a hydraulic cylinder, to the other, outer die part, which can be driven using an eccentric drive. In order to provide advantageous forging conditions, the forging ingot is formed under heat, first using the forging dies driven by the eccentric drive, in near-surface forge processing with a degree of deformation which is above the critical degree of deformation and which excludes the formation of cracks, and then, with the outer die parts stopped, with the aid of the inner die parts driven by the hydraulic cylinders, in forge pressing with a bite ratio of >0.5.

At least one device enables the implementation of a metal additive manufacturing method. At least one raw material is in the metal additive manufacturing method. A feeder is located on the device and enables the raw material to be deposited. A heat source is located on the device and enables the raw material from the feeder to be melted. A table enables the raw material to be processed thereon. A part is formed by melting and processing the raw material on the table using the heat source. A forging element provides improvement in the micro- and/or macrostructure of the part by exerting force on the part under the control of a user and/or automatically. A base is provided on which the device is located. A control unit enables the position of the table to be changed with respect to the base.

A safe control apparatus (10) for adjusting the stroke length of an eccentric press (100), wherein the eccentric press (100) has a plunger (102) that is driven via a connecting rod (104) by an eccentric system (106) that comprises an eccentric shaft (108) and an eccentric bushing (114) that can be released from one another and then rotated against one another for the adjustment of the stroke length; wherein the control apparatus (10) has an encoder (12) for determining the rotational position of the eccentric shaft (108) and a control logic (10) to generate a first switching signal at at least one first rotational position (BDC, TDC). The control logic (10) is here configured to automatically readjust the first rotational position (BDC, TDC) on an adjustment of the stroke length.
