The invention discloses a dragging length-measuring thin plate hydraulic cutter. An upper cross beam is fixed on an open door frame, a hinge seat is arranged on the upper cross beam, the upper end of a guide post is hinged with the hinge seat, the lower end of the guide post is respectively connected on a baseframe, symmetric guide frames are fixedly connected on the two sides of an upper
cutting blade, guide sleeves arranged on the guide frames are in movable fit with the guide post, idler wheels of the guide frames are matched with a lining plate of the open door frame, a suspension beam is fixedly connected onto the open door frame, a cylinder and the guide sleeves in fit with the guide post are all fixed on the suspension beam, the end part of a
piston rod of the cylinder and the lower end of the guide post are connected with a movable base plate, a rubber roller is mounted on the back surface of the movable base plate, a motor drives the rubber roller to rotate, a built-in bearing and an
encoder connecting rod structure are arranged, and a free roller matched with the rubber roller is arranged on the baseframe. The dragging length-measuring thin plate hydraulic cutter disclosed by the invention has multiple using functions and has the advantages of flattening
strip steel,
centring, dragging and auxiliary strip penetrating,
cutting head,
tail and middle part of the
strip steel,
cutting and shunt winding, accurately measuring length and speed of the rolled
strip steel and the like, improving strip penetrating speed and cutting speed, ensuring production safety and improving production efficiency.
