STAMPING DEVICE, METHOD OF STAMPING, COMPUTER SOFTWARE PRODUCT AND DATA CARRIER Russian patent published in 2008 - IPC B21D22/02 

FIELD: technological processes.

SUBSTANCE: for stamping use the device containing a punch, a pattern, a clip, at least, one of two tools, one of which is a tool of input of material characteristics, and the second - tool of their measurement. Besides, the device is equipped with the detector of state variable, computing tool of processing conditions and the controller of processing conditions. Input and measure, at least, one characteristic of a material from the group of characteristics including width of a sheet, a yield point, 0.2% of relative yield point, strength on rupture, elongation, value n, value r, dependence between voltages and a strain, hardness, temperature, surface roughness, coefficient of friction, width of a lubricant film. In addition measure, at least, one state variable from the group including response of a punch, pattern temperature, magnitude of a strain of the pattern, magnitude of a strain and temperature of treated preform. Evaluate, at least, one processing condition. On the basis of results of evaluation inspect, at least, one processing condition from the group of conditions including speed of migration of a punch or the pattern, pattern temperature, effort of a clip of preform.

EFFECT: improvement of article quality.
