METHOD OF IDENTIFYING ELASTIC AFTERWORKING CAUSE, METHOD OF DISPLAYING INFLUENCE OF ELASTIC AFTERWORKING, METHOD OF IDENTIFYING LOCATION OF ELASTIC AFTERWORKING CAUSE, METHOD OF IDENTIFYING POSITION OF ELASTIC AFTERWORKING PREVENTER, DEVICES FOR THEIR IMPLEMENTATION AND PROGRAMMES Russian patent published in 2011 - IPC B21D22/00 B21D5/01 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and may be used for afterworking data processing Metal forming conditions are numerically analysed to obtain forming data for sections of part being formed. Magnitudes of physical property and quantitative magnitudes of physical property of aforesaid sections are processed. Elastic afterworking magnitude is calculated proceeding from aforesaid processing results. Data are processed once more and elastic afterworking is calculated for varying sections of formed part to identify region wherein elastic afterworking makes minimum, or difference incorporating elastic afterworking without aforesaid processing makes maximum. For this, proposed device is used incorporating forming analyser, elastic afterworking analyser, processor to process results, carrier of records read off by computer incorporating programme that allows identifying location of elastic afterworking origination cause.

EFFECT: reduced elastic afterworking.
