FIELD: instrument engineering. ^ SUBSTANCE: according to the method the blank of hanger is made taking direction of rolled stock into account. Then blank is subject to thermal processing, both sides of blank are cleared from material and hanger is formed by means of double-sided shaped embossing. According to the first variant of the method, blank is subject to heat-cyclical processing prior to double-sided embossing. According to the second variant, double-sided shaped embossing is made in two steps and heat-cyclical processing is performed between those two steps. ^ EFFECT: prolonged life of hanger; increased service life of press tool. ^ 2 dwg, 2 ex |
