废钢剪切机工作原理：由电力电机驱动液压传动装置(无电源的地方可用柴油机作动力)，液压传动装置驱动压料机构和剪切机构，达到切断钢板的目的。
Working principle of scrap shearing machine: the hydraulic transmission device is driven by electric motor (diesel engine can be used for power supply where there is no power supply). The hydraulic transmission device drives the pressing mechanism and shearing mechanism to cut off the steel plate.
一般来讲，钢板剪切机的剪切口，由上下两个刀片组成，下刀片多为固定刀片，上刀片为活动刀片。当废钢进入刀口，压料装置下压固定废钢，然后上刀片向下运动切断废钢，切断后上刀片和压件机构回升至原始位置等待下次剪切过程，如此循环
Generally speaking, the shear opening of steel plate shearer is composed of upper and lower blades. The lower blades are mostly fixed blades and the upper blades are movable blades. When the scrap enters the knife edge, the pressing device presses down to fix the scrap, and then the upper blade moves downward to cut off the scrap. After cutting, the upper blade and the pressing part mechanism rise back to the original position and wait for the next shearing process, so as to cycle
