一、摆辗法兰管接头的模具结构法兰管接头是管道的连接件,要求具有一定强度、韧性和气密性。尤其在各种高压管路中,对法兰接头的要求更为严格。目前法兰管接头均采用铸造、锻造或液态模锻等方法成型。用铸造方法生产的法兰盘一般存在缩松、缩孔等各种铸造缺陷,制件满足不了使用要求。用锻造方法加工的法兰盘可消除上述铸造缺陷,但要求有制坯工序,从而提高了制件成本。液态模锻集铸-锻为一体,简化了生产周期,提高了产品质量。若法兰的尺寸和比压值
First, swing roller flange fittings die structure flange fittings pipe fittings, requires a certain strength, toughness and air tightness. Especially in a variety of high-pressure pipeline, the flange joints more stringent requirements. Flange fittings are currently used casting, forging or liquid forging and other methods of molding. Flanges produced by the casting method are generally shrinkage, shrinkage and other casting defects, parts can not meet the requirements. Flanges machined by the forging method eliminate the casting defects described above, but require a billet process, thereby increasing the cost of the parts. Liquid forging set casting - forging one, simplifying the production cycle and improve product quality. If the flange size and pressure values
