对于連續冲模或复合成形模的結构設計,一般不宜动作过多,組成模具的零部件不宜排列太挤,以免在使用过程中发生卡住現象,或者使維修困难,以致不能长期使用。本文介紹的連續冲模,沒有上述缺点,用于內徑2.8毫米、长33毫米有縫管子的冲裁,以0.6毫米厚的黄銅带料一次完成落料、弯曲、压圓三道工序,所冲条料寬度即等于制件长度(33毫米),前后間隙无廢料。模具結构如图1所示,落料凸模7紧靠在弯曲凸
For continuous die or composite forming die structure design, generally should not move too much, the composition of the mold parts should not be arranged too crowded, so as to avoid the phenomenon of stuck in use, or make maintenance difficult, so can not be long-term use. This article describes the continuous die, without the above shortcomings for the inner diameter of 2.8 mm, 33 mm long slit pipe blanking to 0.6 mm thick brass strip material to complete a blanking, bending, pressure round three processes, the impulse The width of the strip is equal to the length of the piece (33 mm), there is no waste before and after the gap. Die structure shown in Figure 1, blanking punch 7 close to the curved convex
