Method of manipulating and forming material at temperatures between solidus and liquidus

Abstract

A method of manipulating and forming material where the material is a metal blank. The blank is inserted into an electromagnetic field that keeps it in levitation and heats it up to the temperature between solid state and liquid state. Temperature is measured by infrared thermometer. After the blank reaches the required temperature it is formed to the desired shape by external force. The temperature changes during the forming phase and this change can be controlled or uncontrolled. Forming of levitated blank is done by changing position of levitation device by inserting the blank between forming tools or levitated blank stays in place and forming tools move towards it and then the forming takes place.

1 . Method of manipulating and forming material at temperatures between solid and liquid states where the material is a metal blank where the method is characterized by the fact that the blank is inserted into an electromagnetic field of a levitation device that keeps it in levitation and heats it up to the required temperature, temperature is measured by contact-less thermometer, after blank reaches the temperature between solid state and liquid state it is formed to desired shape by external force and at the same time con rolled or uncontrolled change of blank temperature occurs. 
   
   
       2 . Forming of levitated blank according to  claim 1  is done by changing position of levitation device by inserting the blank between forming tools. 
   
   
       3 . Forming of levitated blank according to  claim 1  is carried out so that the levitated blank stays in place and forming tools move towards it and then forming occurs.
