Technical Field

The application relates to the field of metallurgy, especially, relate to a novel step-by-step cold bed.

Background

The walking beam and the walking beam are driven by hydraulic cylinders respectively. When the stepping cooling bed works, firstly, the lifting cylinder works, the travelling wheel of the lifting beam rolls along the lifting inclined plane, so that the stepping beam is lifted to a position higher than the fixed beam, and a casting blank on the fixed beam is supported; then the stepping cylinder works to move the stepping beam forward for a certain distance; the lifting cylinder enables the lifting beam to descend, the casting blank falls onto the fixed beam again, and the casting blank advances by one tooth forwards and turns over one surface; and finally, the stepping cylinder drives the stepping beam to return to the original position.

However, the self weight of the parts such as the lifting beam and the walking beam and the weight of the casting slab are large, and therefore, a large driving force is required to be provided when the lifting beam rises, and a large braking force is required to be provided when the lifting beam descends, which makes a high demand for a driving device. Meanwhile, the lifting form requires that the lifting slope has enough length to meet the lifting requirement of the equipment, the too large angle of the lifting slope can increase the stress of the driving oil cylinder, which can cause the waste of energy of the lifting driving oil cylinder, and in addition, the lifting oil cylinder also needs to have enough stroke, when the stepping cooling bed needs to be capable of storing more steel billets, the force and the strength which need to be borne by the lifting driving oil cylinder and the rotating arm of the driving shaft need to be increased in multiples, which can cause the equipment to be heavy, the waste of manufacturing materials and energy, and the cost of the equipment is higher.
