隔环锻造工艺分析及模具设计 摘要：采用自由锻可以减少生产时间，降低生产成本，提高生产效率，胎模锻可以减轻工人的劳动强度，使锻件的质量和产量进一步提高，降低金属的的消耗，工艺操作灵活，制造经济简便，可在一种锻锤上锻出形状较复杂的锻件。 本设计详细的论述了自由锻，胎模锻的全过程。自由锻（含胎模锻）是指借助简单的工具，如锤、砧、型砧、摔子、冲子、型铁等对铸锭或棒材进行镦粗、拔长、弯曲、冲孔、扩孔等方式生产零件毛坯，胎模是在自由锻锤上采用活动锻模进行模锻生产的一种工艺方法。 隔环是一个形状比较简单的环形件，所用的材料时45号钢，而且是一定尺寸的圆钢。需要的工序有镦粗-胎模锻。经工艺计算和分析确定了合理的锻造工艺方案，提出了选用自由锻方法将坯料预锻成接近锻件的形状，然后在胎模中最终锻制成形。在自由锻前要经过尺寸计算得到坯料的尺寸和质量，采用锯切的方法将圆钢以一定的尺寸下料，选用接触电加热炉将坯料加热。然后经过各个锻造工序最终将毛坯锻造成锻件。 关键词：隔环；；Every ring forging process analysis and die design Abstract:Using free forging can reduce production time, reduce production cost, improve production efficiency, tire die forging can reduce the labor intensity of workers, the forging quality and production to further improve, reduce the consumption of metal craft operation is flexible and convenient manufacturing economy, can be in a forging hammer forging shape more complex forging. This design detailed discusses the free forging, tire die forging process. Free forging (including tire die forging) refers to using simple tools, such as hammer, anvil, anvil, child, punch, such as iron ingot or bar for upsetting, drawing out, bending, punching, expanding production parts blank, tire mold is on free forging hammer forging die forging production using activity of a kind of technological process. Spacer ring is a ring shape is simple, the material of 45 # steel, and it is of a certain size. Need to process have a upsetting - die forging. The process calculation and analysis to determine the reasonable forging process scheme, puts forward a method to choose the free forging billet pre forging into close to the shape of the forgings, and then final forging is made in the tire mold. Should pass before free forging size to calculate the size and quality of the billet, adopt the method of sawing materials will round steel to a certain size, selection of electrical contact heat the billet heating furnace. And then through the various forging process will end up blank forging forgings. Keywords: distance
