平行刃剪切机
Parallel Edge Shearing Machine
平行刃剪切机的两个剪刃是彼此平行的，它通常用来在热态下横向剪切方形及矩形断面的钢坯。也可用来冷剪型材，将刀片做成成型剪刃来剪切非矩形断面的轧种。
The two cutting edges of a parallel-edged shearing machine are parallel to each other. It is usually used for transversely shearing billets with square and rectangular sections in hot state. It can also be used for cold-shearing profiles. The blade is made into a forming cutting edge to cut the rolling seeds of non-rectangular cross section.
平行刃剪切机按剪切机构的运动特点，分为上切式和下切式两种型式。
According to the movement characteristics of the shearing mechanism, the parallel-edge shearing machine can be divided into two types: upper-cutting type and lower-cutting type.
上切式剪切机的下剪刃是固定的；由上剪刃的上下运动进行剪切。其剪切机构通常采用：曲柄连杆机构。
The lower cutting edge of the upper shearing machine is fixed; the upper and lower movement of the upper shearing blade is used for shearing. Its shearing mechanism usually adopts crank-connecting rod mechanism.
下切式剪切机的两个剪刃都运动，剪切过程是通过下剪刃上升来实现剪切的。其剪切机构通常有偏心轴式和浮动式。
The two cutting edges of the downward shearing machine move, and the shearing process is realized by raising the downward cutting edge. Its shearing mechanism usually has eccentric shaft type and floating type.
平行刃剪切机，在工作时能承受的最大剪切力是它的主要参数，故人们习惯上以最大剪切力来命名。
Parallel-edge shearing machine, the maximum shear force that can be endured when working is its main parameter, so people are accustomed to name it with the maximum shear force.
