飞剪是在轧件运动中对轧件实施剪切工艺的一种设备，是连续式轧钢生产线上不可缺少的、非常关键的设备之一。飞剪机属于热剪，主要对轧件进行切头、切尾、事故碎断以及备尺分段。　　 　　随着轧钢工艺发展及钢厂产能扩张的改造需要，对轧钢设备提出了更高的要求，主要体现在大轧制断面和高轧制速度两方面。我公司设计制作的飞剪，能够完美的匹配以上两个要求。　　 　　同时我公司能根据客户实际需求，进行非标设计，满足特殊轧钢

我国是一个钢铁生产及消耗大国，钢铁产业是我国的一大支柱产业。　　南京金鑫的产品主要是面对各大钢铁厂，在钢厂的轧钢条线中占一定比例。　　车间所用原料(连铸坯)由辊道运至轧钢车间原料跨，冷坯按炉号分钢种堆放在跨内备用。全车间机械、电气设备、液压润滑及水等流体系统均做好生产准备后，由上料吊车将检验合格的原料吊到步进上料台架上，坯料逐根向前步进，单根坯料步进至辊道上通过入炉辊道送入加热炉内加热。热坯经过热

在轧制线速度不断提高的情况下，成品机架的轧件速度已达14m/s，在这样高的速度下进行轧制时，要求将钢材的头、尾切去lOOmm左右。因为钢材的头、尾不规则，会造成堆钢事故，且钢材两头温度比较低，有时会出现黑头，如不切去，就可能引起下一个机架过流造成快开跳闸等较大事故。因此设置切头、切尾以利轧线的顺利进行。　　 　　依据轧线的工艺要求，可将飞剪的一个动作周期分为四个部分。如图(一)附后。　　(1)当轧
Flying shear cutting control process

Flying shear cutting control process

A自动时：光电检测信号→经由电平转换→PLC系统→发出，剪切信号→施加速度给定→飞剪加速从零位起动→至剪切点剪切→到制动位→给出正爬指令→至甩距位→给出反爬指令直至剪刃到达零位→PLC发出停车指令。　　 　　B手动时：　　手动操作和自动操作基本一样，只是外部来信号将“光电检测信号”变为操作台上的“切头/切尾选择”信号。　　 　　C碎断操作：即事故时连续定尺剪切。操作台给定碎断信号后，经过光电隔离，

飞剪机用来横行剪切的轧件。它可以装在连续式轧机的轧制作业线上，亦可装在横切机组，连续镀锌机组等连续作业精整机组上。随着连续轧机的发展，飞剪机得到越来越广泛地应用。　　 　　飞剪机的特点是能横向剪切运动的轧件，对它有三个基本要求：(1)剪刃在剪切轧件时要随着运动的轧件一起运动，即剪刃应该同时完成剪切和移动两个运动，且剪刃在轧件运动方向的瞬时分速度V应与轧件运动速度VO相等或大2～3﹪，在剪切轧件时，

1)剪切结构　　曲柄连杆飞剪机在剪切轧件时刀片垂直与轧件，剪切断面较为平整。不工作是，刀片停在水平位置上，当有轧件通过时，刀片在竖直位置刀片以大约相同的速度，完成对轧件的剪切此后刀架旋转使刀片又停到原来位置。当需要对轧件进行碎断时，刀架不停旋转完成碎断任务。　　 　　2)机架的设计　　由于工作机座采用单独驱动，采用一级减速器平动传动。设计成齿轮箱式机架。此箱可分为上、中、下三箱。上箱中箱内安装剪切
