超塑成型超塑成型superplastic forming 超塑成型suPerplastic forming超塑性材料在能呈现超塑特性的温度和速度条件下的成型工艺。与传统成型工艺相比,其特点是:①坯料需具有一定的组织状态;②成型是在恒温条件下进行的,工模具与坯料处在同一温度下;③成型过程较慢;④可成型基本上不加工或少加工的精确制品和复杂形状的制品。常用的超塑成型方法可分为超塑性挤压成型和超塑性气压成型。 超塑性挤压成型在传统的挤压加工方法上增加加热条件的成型方法。与等温雄造相类似,’‘但不需要高压力、高能量以及高强度模具。成型设备可用塑料制品液压机(带有上、下加热板),或普通液压机。一般情况下,液压机的滑块速度能满足超塑成型需要。为便于控制速度,可在液压机上附加一个调速装置。成型时的温度场可由加热板提供,也可由加热圈(装在模具周围)提供。超塑挤压成型由3个阶段完成:①初期变形,压力很小,并随变形增加压力缓慢上升;②达一定压力后,出现相对平稳阶段,此时变形量继续增加;③零件已基本成型,为完成细部成型,需增大压力。 超塑性气压成型气压成型是最能充分体现超塑性特点的成型方法。其装置和变形特点与塑料制品吹塑成型相类似,是一种低能量、低压力而能获得大变形量的成型方法。成型装置包括:①装有模具和能夹持板料边框的密封容器。容器带有抽气(真空成型)或充气(加压)孔道。②加热与控温装置。③抽真空装置或各种工作气体的压力容器。成型时,材料一开始是自由变形,宜用小压力以获得尽量均匀的壁厚。当材料与模具接触后,所接触部位由于摩擦阻力几乎不再变形。最后,需填充模具的细部,如模具的角隅、沟槽,此时则需大压力。通常,气压成型不易获得壁厚均匀的制件。为改变这种状况,可采取多种措施,如采用不均匀的加热温度场、变厚度的坯料、预反向成型等。 在超塑性气压成型基础上,还发展了超塑性成型与扩散连结工艺。这种工艺利用了超塑成型时的材料易于变形和易于扩散的活化状态,在一次加热周期中完成了成型与扩散连结两个工序。通过超塑成型和扩散连结,可以使两块或两块以上的板材一次制成所需要的复杂断面形状的构件,常用来制作机翼夹层结构,飞机上的舱门和壁板等。对于一些复杂形状的成型件,为保证质量和工艺的重复性,宜采用计算机来控制整个成型过程。 (王燕文)
