The push-pull cylinder drives the clamping blade to clamp multiple welding strips, while the lifting cylinder drives the cutting blade to move upward to cut them. Combined with the guidance of the needle roller bearing and guide hole, the welding strips are clamped and cut simultaneously.
It effectively solves the problem of synchronizing the pressing and cutting of the welding strip, ensuring that the welding strip does not twist or deform during the cutting process, and has a compact structure and high reliability.
