铜合金带材拉拔用辊模的设计及应用

Design and Application of Copper Alloy Strip Roller Die for Drawing

采用辊模技术替代钨钢拉拔模拉拔铜合金带材,设计了使用寿命长、精度高的辊模结构,结合卷拉机或链条式拉拔机,用于拉拔铜合金带材。结果表明,采用辊模技术可明显改善铜合金带材的表面品质,提高带材平整度,拉拔节能22%左右,且与轧机相比,辊模的结构简单、维护调整方便。用不同孔型的辊模可适用多种规格铜合金带材生产。

Roller die technology substituted for drawing die of tungsten steel was utilized to draw copper alloy strip. The structure of roller die with long service life, high precision and reliability was designed combined with coiling or chain drawing machine to drawing copper alloy strip. The results indicate that the surface quality and flatness of copper alloy strip can be significantly improved by roller die technology, and the energy saving is about 22%. Compared with rolling mill, the roller die with simple structure is convenient to maintain and adjust, and roll dies with different hole patterns can be suitable for a variety of specifications of Cu alloy strip.
