通过试验得出了ЛC59—1黄铜保持架毛坯锻造工艺.锻造毛坯采用砂模或铁模铸铜棒.锻造前棒料于650℃退火3小时并车光.始锻温度730～750℃,在保温时间内要保证棒料烧透.停锻温度600～650℃.锻造比≥2.锻件于280～300℃退火3小时(在空气中冷却).铸造黄铜锻造后,当变形程度达到36%,强度有很大提高,当变形量达到52%以上时,强度增加到37～40公斤/毫米~2,而且延伸率也同时提高.
The ЛC59-1 brass cage blank forging process is obtained through experiments.The forging blank is made of sand mold or iron mold cast copper rod.The bar before annealing is annealed at 650 ℃ for 3 hours and the car is light.The initial forging temperature is 730-750 ℃, During the holding time to ensure that the bar burning through. Stop forging temperature 600 ~ 650 ℃. Forging ratio ≥ 2. Forging at 280 ~ 300 ℃ annealing 3 hours (in air cooling.) Forged brass casting, when the deformation reaches 36% strength has greatly improved, when the deformation of more than 52%, the strength increased to 37 ~ 40 kg / mm ~ 2, and elongation also increased.
