用较大吨位的挤压机挤压截面小于2厘米~2的小规格铝型材,常常因为多孔流速不均而发生模具突然堵损现象,给挤压生产带来了技术上的困难。本文介绍了子母模具技术,可用来解决在较大吨位挤压机上挤压小截面铝型材的问题。
With a larger tonnage of extruder squeeze cross-section less than 2 cm ~ 2 small size aluminum profiles, often because of uneven flow velocity porous mold sudden plugging phenomenon, to extrusion production has brought technical difficulties. This article describes the master-die technology that can be used to solve the problem of extruding small-section aluminum profiles on larger tonnage presses.
