过去,异型断面的棒状制品,例如,像钻头、扭拧管那样的制品,是通过机械加工方法来制造。但是,最近,为了降低成本和减少工序,提出了采用锻压挤压机来进行塑性成型。采用塑性成型方法,能够生产各种形状的制品,所以,该方法是一项非常有意义的技术。本文在介绍一般锻压挤压法的同时,还介绍了锻压挤压机的代表机种的形式及实例。
In the past, rod-shaped products with irregular cross-sections, for example, products such as drill bits and twist pipes, were manufactured by a machining method. However, recently, in order to reduce costs and reduce the number of processes, a forging press was proposed for plastic molding. Using plastic forming method, can produce a variety of shapes of products, so this method is a very meaningful technology. This article describes the general forging extrusion method at the same time, also introduced forging extrusion machine representatives of the form and examples.
