变断面型材挤压
extrusion of variable cross section shapes
b ianduanmian xjngeai Jiya变断面型材挤压(extrusion of variable。rossseetion shapes)用挤压法生产断面变化的型材,有阶段变断面型材和逐渐变断面型材之分,主要用作结构材料,它们的挤压方法也有所不同。 阶段变断面型材的挤压方法有双位楔法和可拆卸模法两种: (1)双位楔法(图1)。在型材前端经第1模成形挤压后,松开压紧楔,后端部分用第2模挤压.氯篡嘟豁 图1双位楔法挤压阶段变断面型材 1一压紧楔;2一第1模;3一第2模 (2)可拆卸模法。可拆卸模由3~4个模块组成。首先将小断面的可拆卸模装在模支承中并移至桥压筒进行挤压。挤压完毕后,移开模支承,同时,将模子同型材和模支承脱开,换上可挤压大断面型材的可拆卸模,并将模支承再移至挤压筒进行挤压。 逐渐变断面型材的挤压方法有可移动模法和带锥度异形针法两种. (D可移动模法(图2)。在挤压过程中,活动模块借助于仿形尺的作用改变位置(上升或下降),从而逐渐改变模孔的形状和尺寸,挤出逐渐变断面型材。臀 图2可移动模法挤压逐渐变断面型材 1一不动模;2一活动模块;3一保护环;4一挤压筒;5一仿形尺 (2)带锥度异形针法。采用带有锥度的异形针和相应的异形模挤压。 (王祝堂)
