    • It is intended to improve work efficiency by eliminating the work of attaching and removing push rods during installing and dismounting the a blade mount and also to reduce abrasion of the push rods for pushing punching scrap out of a punching blade. The first push rods 18 are inserted moveably in the first through-holes 16 formed in the knife cylinder and the second push rods 36 are inserted movably in the second through-holes 34 formed in the blade mount to permit the second push rods 36 to be abutted on the first push rods 18. A scrap push lever 30 is mounted on the outer end of the second push rod 36 to push out the punching scrap a and an eccentric cylinder 14 is provided inside of the knife cylinder 10 to push the first push rod 18 outward when pushing out the punching scrap a. The stroke of the first push rod 18 is controlled so that the outer end 18a of the first push rod 18 does not project from the outer periphery 10a of the knife cylinder. The first push rod 18 and the second push rod 36 are preferably made from one of self-lubricating resin and abrasion-resistant material.
    • 旨在通过消除在安装和拆卸刀片安装件期间附接和移除推杆的工作来提高工作效率,并且还减少用于将冲压件从冲压刀推出来的推杆的磨损。 第一推杆18可移动地插入形成在刀筒中的第一通孔16中,并且第二推杆36可移动地插入形成在刀片安装件中的第二通孔34中,以允许第二推杆36为 邻接在第一推杆18上。废料推杆30安装在第二推杆36的外端上以推出冲压件a,偏心缸14设置在刀缸10的内部,以推动第一推杆 杆18向外推出冲压件a。 控制第一推杆18的行程使得第一推杆18的外端18a不从刀筒的外周10a突出。 第一推杆18和第二推杆36优选地由自润滑树脂和耐磨材料之一制成。
