提高级进模性能

中文译文
提高级进模性能(中文4400字,英文2700字)
级进模是一种成本低廉且安全的零件制造方法,. 精心设计模具结构可确保最佳性能。一副级进模在一次冲压动作中可在模具不同工位进行不同的冲压操作。这些在通过模具的带料上同时进行的冲压动作制造出零件。每个工位可进行一个或多个操作，但要生产出完整的零件条料必须经过每一个工位。而零件依靠零件之间的载体输送到各个工位，并在最后一个工位进行切除。
为了使模具性能最佳，在设计和制造级进模具时，必须考虑以下五个方面：
•    研究零件
•    送料方式
•    零件顶出和送进
•    设计零件载体
•    压料装置

     Improving Performance of Progressive Dies
Progressive die stamping is a cost-effective and safe method of producing components. Careful design and construction of dies will ensure optimum performance.
A progressive die performs a series of fundamental sheet metal operations at two or more stations in the die during each press stroke. These simultaneous operations produce a part from a strip of material that moves through the die. Each working station performs one or more die operations, but the strip must move from the first station through each succeeding station to produce a complete part. Carriers, consisting of one or more strips of material left between the parts, provide movement of the parts from one die station to the next. These carrier strips are separated from the parts in the last die station.
There are six elements that should be addressed when designing and building a progressive die to maximize its performance:
•    Interpreting the part print,
•    Starting material into the die,
•    Part lifters and part feeding,
•    Flexible part carriers,
•    Upper pressure pads, and
•    Drawn shells.
