本发明的轧机压力咬入装置,具有超过轧件压力咬入力的夹紧功能;同时,当轧件被工作辊咬入使其受拉时,该装置可松开夹紧辊装置,使其容易地向其进行方向前进而不会造成划伤。本发明的压力咬入装置的作用原理如下。用前拉料辊31把轧件18的前端送出,使其通过上、下夹紧辊10,11及上、下压头4,5之间,一旦到达压力咬入作业最有利的位置时,由在前拉料辊31上安装的回转检测器(图上未表示)发出的指令,使液压缸7,8下降;同
The rolling mill pressure bite-in device of the present invention has a clamping function exceeding the bite-in force of the rolling stock and, at the same time, when the rolling stock is tightened by the work roll to pull it, the apparatus can release the nip roll apparatus to make it easy Go forward in a direction that will not cause scratches. The operation principle of the pressure bite-in device of the present invention is as follows. The front end of the rolled material 18 is fed by the front pulling roller 31 and passed between the upper and lower pinch rollers 10 and 11 and the upper and lower rams 4 and 5 to reach the most favorable position for the pressure bite operation, The hydraulic cylinders 7, 8 are descended by a command issued from a rotation detector (not shown) attached to the front pulling roller 31;
