铆钉克子又称为铆钉窠,是我们船厂中使用最多的一种风动工具。它专用来铆平铆钉的尾端,因此必须具有相当高的硬度和强度,以防止在工作中变形和磨损(凹陷),同时又要有足够的韧性,以免受到冲击而崩裂。我厂的铆钉克子构造如图1,材料是y8钢,要求硬度为Rc55～58。过去是采用一般的方法来处理,即加热到780～800℃,保温后全部淬水冷却和180～ Knitted rivets, also known as rivets, are the most commonly used pneumatic tools in our shipyards. It is designed to riveted the end of a rivet and must therefore have a very high hardness and strength to prevent deformation and wear (indentation) during work while still providing sufficient toughness to avoid cracking by impact. I plant the rivets Kerry structure shown in Figure 1, the material is y8 steel, the required hardness Rc55 ~ 58. The past is the use of general methods to deal with, that is, heated to 780 ~ 800 ℃, all quenched and cooled after cooling and 180 ~
