锻造的连杆毛坯，在实施断裂剖分之前，先粗镗连杆大头孔，然后在其预定断裂处加工两个对置的沟槽，为应力集中点，见图 1a。随后，将连杆大头孔套装到一台进行断裂剖分的装置的两个半芯轴上，并将连杆进行定位和夹紧。然后利用冲击力，将用来胀裂连杆的楔插入上述半芯轴中，此时在楔的冲击下，连杆的大头孔在沟槽处被断裂剖分为连杆体和连杆盖这种新工艺，使分离后的连杆和连杆盖能直接在断裂面处自然精确合装，无需加工配合面，达到了减少加工工序和减少加工机床的目的。此外，除连杆剖分面具有较高的配合精度外，

还由于其剖分接触面是凸凹不平的，大大提高了接触面积，从而提高了连杆承载能力。1.脆性断裂该工艺的理论基础是断裂力学中的脆性断裂理论。据断裂力学可知，断裂过程中裂纹表面通常有三种位移形式，即张开型、前后滑移型、平面剪切型。当物体受垂直于断裂平面的正应力拉力时，属张开型断裂，这是脆性断裂产生的形式和条件。脆性断裂具有以下发生特点：1)断裂时承受的工作应力较低，通常远远低于材料的屈服强度，塑性变形小；2)断裂受温度影响较大；3)断口方向与正应力相垂直。连杆断剖工艺正是依照脆性断裂的上述特点，通过在连杆大头内侧开出v型槽，然后施加垂直于预定断裂面的正应力，满足脆性断裂的发生条件，使连杆体一盖在不发生塑性变形的情况下被分离。应关注以下几个问题：1)毛坯材料；2)v型槽形状与所需应力关系；3)操作温度。
