Abstract

The invention discloses a casting roller bottom box demolding device. The device comprises a working platform, a workpiece fixing device, a demolding ejection device and a PLC system, wherein the workpiece fixing device is installed on the top surface of the working platform, the demolding ejection device is installed on the bottom surface of the working platform, and the workpiece fixing device and a driving component on the demolding ejection device are electrically connected with the PLC system. The equipment is ingenious in concept, workpieces are stably and reliably positioned through a plurality of clamping jaws, work of an ejection roller is safe and reliable, the damage to a bottom box is avoided, the whole operation process is automatically controlled, the equipment is convenientand rapid to use, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of roll casting equipment, in particular to a casting roll bottom box demoulding equipment. Background technique [0002] After the roll is cast, it needs to be taken out from the mold. Due to the special casting process of the roll, the lower roll neck of the roll is connected with the casting tube. After the molten iron is solidified and formed, the solidified product of the lower roll neck of the roll and the molten iron in the casting tube forms a Y-shaped structure. It is very difficult to take out the rolls from the molding sand in the bottom box. In the past, the impact method was used to take out the rolls, that is, use a crane to lift the upper part of the rolls, so that the rolls are suspended in the air, and use the crane to switch the walking direction to make the rolls swing and hit hard objects until the molding sand is hit. After the bottom box falls off after loosening, the disadvantages of t...
