摘要： A pneumatic cylinder and piston assembly is provided with a piston rod on the end of which is mounted a punch. The cylinder is provided with an extension tube through which the piston rod and punch extend. The assembly is mounted on a support frame have a bored body and a pair of spaced lateral brackets. The assembly is held in the body with the extension tube passing freely through the brackets. A die is mounted on the frame at a position in counter opposition to said punch whereby a rivet may be driven into materials to be joined and clinched by said punch on driving of said piston. The apparatus includes a stopper mounted about the piston rod to limit the movement of said piston rod in said cylinder and restrict the maximum protruded position of the punch, a spacer mounted about the extension tube and located between the body and the lower bracket to define the optimum driving of the punch, and a nut threaded over the extension tube for securing the extension tube to the lower bracket.
摘要翻译：气动缸和活塞组件设置有活塞杆，其端部安装有冲头。气缸设有延伸管，活塞杆和冲头穿过该延伸管延伸。组件安装在支撑框架上，具有钻孔体和一对间隔开的侧面支架。组件保持在主体中，延伸管自由通过支架。模具在与所述冲头相反的位置处安装在框架上，由此在驱动所述活塞时，铆钉可以被驱动成待被接合的材料并被所述冲头铆接。该装置包括安装在活塞杆周围的止动件，以限制所述活塞杆在所述气缸中的移动并限制冲头的最大突出位置，隔离件围绕延伸管安装并位于主体与下支架之间，冲头的最佳驱动以及螺纹穿过延伸管的螺母，用于将延伸管固定到下支架上。
