A method for work piece correction including providing a work piece and analyzing its geometry. Based on the analysis, the method includes determining an initial design of simulated clamp blocks and conducting an initial computer-simulated analysis of work piece correction using the initial design. The method includes determining whether the initial computer-simulated analysis meets predetermined performance criteria and iteratively repeating additional computer-simulated analyses using additional designs until a final clamp block design produces results that meet predetermined performance criteria. The method includes forming clamp blocks based on the final clamp block design, installing the clamp blocks into clamps of a clamping system, and applying extrusion corrections to the work piece.

In the context of a forming method for producing a helical toothing of a cylindrical workpiece by extrusion, a relative movement of a forming tool and of a workpiece blank carried out in a peripheral direction of the forming tool and of the workpiece blank is superimposed on an axial forming movement of the forming tool and of the workpiece blank. Due to a forming relative movement of the forming tool and of the workpiece blank resulting from the mutual superimposition of the axial forming movement and the forming movement in the peripheral direction, the helical toothing of the workpiece is produced on the workpiece blank, in that the forming tool engages, with a shaping helical toothing, in the workpiece blank during the resulting forming relative movement. A forming machine is designed to carry out the aforementioned method.

A technique for optimizing metal extrusion process parameters includes receiving values representing properties of an extrusion press machine, and calculating an estimated surface exit temperature of a metal work product resulting from an extrusion of a metal billet using the extrusion press machine based on the machine property values, an initial temperature of the metal billet prior to the extrusion, an extrusion force applied to the metal billet during the extrusion, and an extrusion speed of the metal work product. The estimated surface exit temperature of the metal work product is compared with a target hot shortness exit temperature of the metal work product. The initial temperature of the metal billet, the extrusion speed, and the extrusion force are changed based on the comparison until the estimated surface exit temperature equals the target hot shortness exit temperature.

In a method for monitoring a functional state of a shaping tooth arrangement on a forming tool, at measurement times which are temporally staggered with respect to each other at a plurality of measurement locations on the shaping tooth arrangement, a tooth arrangement force is measured which acts on the shaping tooth arrangement. At each of the measurement times for each of the measurement locations an instantaneous local tooth arrangement force is thereby determined. A previous instantaneous local tooth arrangement force and a subsequent instantaneous local tooth arrangement force are correlated with each other to determine a local state identification value. On the basis of the local state identification values associated with the measurement locations, information is obtained relating to the functional state of the shaping tooth arrangement.

The invention relates to a press for extruding metal material. The press comprises a hydraulic oil circuit for controlling one or more extrusion pistons movable within corresponding cylinders. Such a circuit comprises a fixed displacement, circulation pump operated by an electric motor with variable rotation speed. The hydraulic circuit comprises a main line and a branch line, along which a shutoff element is arranged. The hydraulic circuit comprises a hydraulic control unit comprising a pilot valve arranged along a pilot line provided with a first segment communicating with the main line and a second discharging segment. Said hydraulic unit is provided to move the shutoff element between an opening position and a closing position of the branch line according to the difference between the oil pressure upstream of the shutoff element and that in the first segment of said pilot line. The hydraulic circuit further comprises a control element which, in an activation condition, and as a result of the activation of said pilot valve, determines a gradual increase of the pressure in the first segment of said pilot line and a corresponding gradual closing movement of said shutoff element causing a consequent gradual increase of the thrust on the piston until the reference speed is reached.
