为了满足科研、生产的需要,一九七八年以来,我厂对强力旋压技术作了深入的研究。加工材料有:铝、铜、钢、钛、铌等多种合金。零件形状有:筒形、筒形收颈、锥形、曲母线复合形、折迭形等。在技术方面,对材料可旋性、毛料选择、工艺参数、模具设计、冷却润滑剂的选择、旋压铺具等都进行了研究和总结,特别是提出和论证了工艺余量计算公式和强力旋压次数公式,先后生产出重要旋压件50余项3500多件,均用于飞机、导弹、火箭、
In order to meet the needs of scientific research and production, since 1978, our factory made a thorough research on the powerful spinning technology. Processing materials are: aluminum, copper, steel, titanium, niobium and other alloys. Part shapes are: cylindrical, cylindrical neck-closed, tapered, curved complex lines, folding and so on. In terms of technology, materials spinnability, choice of wool, process parameters, mold design, selection of cooling lubricant, spinning and laying are all studied and summarized, especially the formula and strength of process margin are proposed and demonstrated Spinning times the formula, has produced more than 50 important items of more than 3,500 pieces, are used in aircraft, missiles, rockets,
