USE OF THE DEVICE TO INCREASE THE PLASTIC PROPERTIES OF COLD-SHAPED FITTINGS
Abstract
The subjects of influence of the relationship of a limit of fluidity and full relative lengthening at the maximum load on deformation energy before destruction are considered in the article. Use of the block to decrease of internal tension in production of cold-shaped fittings allows to increase significantly its plastic properties, i. e. a power factor. At the same time combination of such device with the straightening unit similar to one used in production of thin wire and also minimization of specific reduction opens prospects for obtaining all necessary parameters of the fittings of a class «B» produced by cold rolling.
