Elaboration and investigation of the technological lubricants for separating and form changing operations at the cold stamping

Abstract

This paper shows the results of laboratory and factory experimental investigations on the effectiveness of technological lubricants, which are used in separating and form changing operations of cold stamping. The firmness of working elements of the dies is experimental valued by using different types of the lubricants.

Lucrarea prezintă rezultate experimentale de laborator şi de uzină privind eficacitatea lubrifierii în cadrul operaţiilor de tăiere şi formare de deformare plastică la rece. Se folosesc mai multe tipuri de lubrifianţi şi se estimează prin încercări durabilitatea elementelor active ale ştanţelor.
