Abstract
A forging system comprises a furnace with heating elements to heat a billet which is pressed against a die at a controlled rate and pressure. A signal processor controls the temperature, pressure and rate as a function of parameters entered on a keyboard the signal processor displays those parameters along with real time values of temperature pressure and distance for the billet in a graphical interface that includes a model of the billet and furnace with elements that change size during the forging processor. Forging pressure is displayed, in this interface, on an incremented bar.
Claims16
A forging system, comprising a furnace for heating a billet and a ram for moving the billet against a die, characterized by:
- a monitor, and
- signal processing means comprising means for generating on said monitor a model of the billet and heating elements in the furnace and for modifying the appearance of said model of the billet as a function of changes in calculated values using sensed billet movement relative to the die, said signal processing means including means for controlling a rate at which the billet is moved by the ram, ram pressure and temperature of said heating elements.
A forging method characterized by the steps of:
- entering initial billet locations and dimensions on a keyboard:
- entering forge temperature and pressure on said keyboard;
- displaying a model of a forge furnace and a model of a billet shown within the model of the forge furnace and on a surface representing a forge ram;
- displaying simultaneously with said model a bar with a height manifesting ram pressure and keyboard buttons corresponding to keys on the keyboard that may be pressed to augment values previously entered on said keyboard;
- and
- changing the appearance of said model and said surface representing the forge ram to reflect movement of the forge ram and changes in the size of the billet as a forging process continues, and changing the height of said bar to reflect measured ram pressure.
A forge system characterized by:
- a forge furnace for heating a billet;
- a ram for moving the billet against a form;
- a connected control console comprising a signal processor keyboard and disk drive and display;
- said signal processor comprising means for providing a plurality of graphic images simulating changes in height and width of the billet during a forging sequence as a function of values computed from measured changes in ram location and time duration from stored functions recalled and processed by said signal processor repetitively during a forging sequence.
A method characterized by the steps:
- heating a billet and pressing the billet against a form with a ram actuator to cause a change in billet location an shape;
- operating signal processing means controlling a display to provide real time graphic images simulating changes in height and width of the billet based on measured changes in billet location and elapsed time for pressing the billet against the form, said changes being applied as values to functions stored in the signal processing means and recalled and processed by said signal processing means during repetitive display update cycles as said billet is pressed against said form to display said real-time graphic images.
