Automatic steel rolling tail cutting device

The utility model relates to steel rolling production machinery, in particular to an automatic tail cutting device for steel rolling. The flying shear comprises a conveying roller way (1) and a flyingshear body (2) with the two ends arranged on the conveying roller way (1) in a striding mode. A hot metal detector (3) is arranged on the side, close to the conveying starting end, of the flying shear (2) in the conveying direction of the conveying roller way (1), the hot metal detector (3) is connected with a time relay (4) through a PLC, and the time relay (4) controls the conveying roller way(1) and the flying shear (2) to be started and stopped respectively. Accurate cutting and continuous production of steel rolling tail cutting are achieved, precision is improved, and labor force is saved. 本实用新型涉及轧钢生产机械，特别涉及一种轧钢自动切尾装置。包括传送辊道（1）和两端跨设于传送辊道（1）上的飞剪机（2），沿传送辊道（1）传送方向，在所述的飞剪机（2）靠近传送始端的一侧设置有热金属检测器（3），所述的热金属检测器（3）通过PLC控制器与时间继电器（4）连接，所述时间继电器（4）分别控制传送辊道（1）和飞剪机（2）的开启和停止。本实用新型实现了轧钢切尾的精准切割和连续生产，提高精度，节省劳动力。
