过去,具有异型断面的棒状制品,例如钻头样的切削刀具是由机械加工的办法制造的,在最近为了缩减成本和工序,使用锻压挤压机以塑性加工的方式成形加工。这种成形加工方法能生产各种各样形状的制品,这是一种有发展前途的技术。本文在说明锻压挤压机的一般情况的同时也介绍有关锻压挤压机的代表性的几种类型和实例。 In the past, rod-shaped products having a profiled cross-section, such as a drill-like cutting tool, were manufactured by machining, and recently, in order to reduce costs and processes, a forging extruder was used for plastic working. This method of forming can produce a wide range of shapes of products, which is a promising technology. This article describes the general situation of forging presses and also presents several representative types and examples of forging presses.
