大连机车厂锻工革新者在技术革新中,开动脑筋在锻造球面垫座时首创了翻边挤压法。锻出的锻件加工留量小节约原材料,过去下料14公斤,现在可节约6.3公斤,提高效率50%,因此此种方法有广泛推广的价值。工艺装备(1)新旧工艺对比锻制如图1球面垫座,过去按表1旧工艺锻造,现在为了提高产量和节约材料,改为如表2新工艺锻造,锻 Dalian locomotive factory forging innovators in technological innovation, start their brains in forging spherical pedestal when the first flange extrusion. Forging the forging process to save the small savings of raw materials, the last unloading 14 kg, can now save 6.3 kg, 50% increase in efficiency, so this approach has a wide range of promotional value. Technology and equipment (1) Comparison of old and new technology Forged Figure 1 spherical pedestal, past the old process forged according to Table 1, now in order to increase production and save materials, as shown in Table 2 new technology forging, forging
