The invention discloses a punching rod reset assembly of a friction punching machine for elevator plates. The assembly comprises supporting legs, beam bodies are arranged at the upper ends of the supporting legs, an assembling plate is arranged between the two beam bodies, vertical plates are arranged at the upper ends of the beam bodies, a top plate is arranged at the tops of the vertical plates, and a punching rod for vertical lifting punching is arranged in the splicing plate and the top plate. The upper end of the punching rod extends out of the top plate, a spring sleeves the extending section of the punching rod, a limiting plate is arranged at the upper end of the punching rod, one end of the spring is in contact with the top plate, and the other end of the spring is in contact with the limiting plate. The limiting plate is arranged at the top extending out of the top plate, the punching rod is sleeved with the spring, the elastic force of the spring acts on the limiting plate, the gravity of a top rod and the gravity of the limiting plate are overcome through the elastic force generated by compression deformation of the spring, and therefore the punching rod is in a lifting state in the initial state; and after a movable pressing wheel tightly presses the punching rod, plate punching operation is achieved directly through anticlockwise rotation of a fixed pressing wheel.
本发明公开了一种电梯板材的摩擦冲孔机的冲杆复位组件,包括支腿,所述支腿上端设置有梁体,两个梁体之间设置有拼装板,所述梁体上端设置有立板,所述立板顶部设置有顶板,所述拼装板、顶板中设置有竖向升降冲孔用的冲杆,所述冲杆上端探出顶板,所述冲杆的探出段套有弹簧,所述冲杆上端设置有限位板,所述弹簧一端与顶板接触,其另一端与限位板接触。本发明通过探出顶板的顶部设置限位板,并在冲杆上套有弹簧,弹簧的弹力作用在限位板上,利用弹簧的压缩变形量产生的弹力克服顶杆、限位板的重力,从而使初始状态下冲杆处于抬起状态,动压轮压紧冲杆后直接通过定压轮的逆时针转动实现板材冲孔作业。
