METHOD OF EXTRUDING ELEMENTS, ESPECIALLY MADE OF METAL, AND A SYSTEM FOR EXTRUDING ELEMENTS, ESPECIALLY MADE OF METAL

摘要

A method of extruding elements, especially made of metal, and a system for extruding elements, especially made of metal, are employed for production of elements by means of extrusion. The material is deflected from the infeed wheel tangentially or at an angle within 90° and is caused to flow locally within the area of the die, by the mandrel's rotary action. This method is executed in a system where in the gap's output area there is a wedge to deflect the direction of exit of the material fed by the rotating infeed wheel, and in the space between the friction block and the deflection wedge there is a mandrel caused to cyclically move bidirectionally at frequency of (0.1-10) Hz, whose face contacts the material in the area of transfer into the die.
