extrusion of panels
b iban』iya壁板挤压(extrusion of panels)壁板是一种宽且扁并带有纵向加强筋条的型材。挤压法是生产壁板的理想方法。 可用挤压法生产壁板的合金有铝合金、镁合金和钦合金，以铝合金为主。壁板主要供航空航天工业用，在舰船、车辆、特种容器、电子设备和热交换装置等方面的应用也日趋广泛。 壁板的挤压方法分实心锭坯法和空心锭坯法两种。 实心锭坯法用实心锭坯挤压平板形壁板的方法最为简单(图a)，但其主要缺点是壁板宽度受限制。壁板的宽度系数(使用圆挤压筒时)与其形状的关系如下:壁板形状-V日CC 宽度系数1 1.6 22·22·35 5 6 sd甘曝彝丽食黔 壁板挤压示意图 a一用实心图锭坯挤压平板形壁板; b一用空心圃锭坯挤压壁板管毛料 1一挤压筒;2一挤压杆，3一挤压垫. 4一锭坯，5一挤压模.6一制品;7一穿孔针 用实心圆锭坯在不同能力挤压机上挤压各种壁板的最大宽度列于表。 用实心圆锭挤压硬铝合金壁板的最大宽度圳甘庄 用扁锭坯在扁挤压筒中挤压平板形壁板是一种先进的挤压方法。用扁挤压筒挤压的平壁板宽度大约等于用圆挤压筒挤压的V型壁板的宽度.用扁挤压筒挤压壁板的最大容许宽度不受挤压机压力的限制，但受挤压机结构特点制约。用扁挤压筒可以挤压变断面壁板，壁板纵向筋条高度和形状不受限制，且纵向筋条高度实际上对壁板宽度无影响。 空心锭坯法用空心锭坯可以挤压壁板管坯(图b)，随后再把它切开、展平并矫直。用这种方法可以制造壁厚相当薄的很宽(2500mm)的壁板。在用空心锭坯挤压壁板时，容易选择适宜的挤压条件，且不受壁板横断面积和厚度的限制;可以挤压异形横断面壁板;可以采用最简单的型、棒材挤压机挤压;由于采用不润滑挤压，壁板表面质量高。缺点是:壁板宽度受到限制，不得超过挤压筒外径的30%~40%;金属流动速度较低;挤压筒使用寿命较短。
