Problems solved by technology

[0004] The stopper rod opening and closing devices of the existing ladles are mostly manually operated, and ladle operators are often exposed to high-temperature radiation and molten steel splashes, which seriously threaten the safety and health of workers
In addition, during the actual pouring operation of the manually operated bottom pouring ladle, the bottom pouring ladle plug rod often swings when the lifting body rises and falls, sometimes the closure is not tight, and sometimes the opening size cannot be effectively controlled, resulting in the pouring melt flow rate Fluctuation, unstable pouring speed, affecting casting quality

Abstract

The invention discloses an automatically-controlled casting ladle plug rod opening and closing device. The technical problems that in the prior art, a plug rod opening and closing device is manually operated, operation is dangerous, safety is poor, and the casting quality is affected are solved. The automatically-controlled casting ladle plug rod opening and closing device is arranged on a ladle body; a connecting rod mechanism comprises a vertical connecting rod and a transverse driving connecting rod; the bottom of the vertical connecting rod is hinged to the middle of the transverse driving connecting rod; a hydraulic system device comprises a vertically-fixedly-arranged hydraulic cylinder; a piston rod of the hydraulic cylinder stretches out of the bottom of the hydraulic cylinder, and the end of the piston rod is hinged to the left end of the transverse driving connecting rod; the bottom end of a vertical plug rod is hinged to the right side of the transverse driving connecting rod; the lower portion of the vertical plug rod is connected with a bottom water filling nozzle of the ladle body; and the hydraulic system device controls the piston rod of the hydraulic cylinder to stretch out and draw back, a vertical sliding rod is driven to move up and down through transmission of the transverse driving connecting rod, and finally the vertical plug rod is driven to move up and down through a transverse arm. The automatically-controlled casting ladle plug rod opening and closing device can be widely applied to the technical field of casting machines.

Description

technical field [0001] The invention relates to the technical field of foundry machinery, in particular to an automatically controlled opening and closing device for a ladle plug rod. Background technique [0002] The traditional molten iron pouring method is to pour the molten iron from the barrel-shaped ladle manually for pouring operation. As the molten iron in the ladle changes, the inclination angle of the ladle must also change constantly. In this way, the height of the molten iron is inconsistent and the flow rate is not stable, resulting in the pressure of the molten iron on the sand mold fluctuating, which directly affects the pouring quality. [0003] The bottom injection ladle can facilitate the operator to quickly align the nozzle with the casting gate, avoid turbulent flow and air entrainment, improve the internal quality of the casting, and is easy to operate, so it is widely used. At present, the plug rod of the most widely used bottom injection ladle is comp...
