Ring Chilled Iron Lifting Tool

Abstract

The invention discloses an annular chilling block hoisting tool, and belongs to the field of slings. The annular chilling block hoisting tool comprises a hoisting rod with the top end provided with a flying ring and three to five X-shaped supports which are evenly installed on the periphery of the hoisting rod and are capable of stretching and contracting. Each X-shaped support comprises a bearing rod and a supporting rod, wherein the middle of the bearing rod and the middle of the supporting rod are mutually hinged. A supporting rod installing disc is fixedly arranged at the lower end of the hoisting rod. A hinge nose is arranged on the outer side of the supporting rod installing disc. The lower end of the supporting rod is hinged to the supporting rod installing disc through the hinge nose. An arc supporting plate is arranged at the upper end of the supporting rod. The middle section of the hoisting rod is sleeved with a bearing rod installing disc capable of sliding up and down along the hoisting rod. A hinge nose is also arranged on the outer side of the bearing rod installing disc, the upper end of the bearing rod is hinged to the bearing rod installing disc through the hinge nose, and a support table is arranged at the lower end of the bearing rod. According to the annular chilling block hoisting tool, the work efficiency in the annular chilling block hoisting process can be greatly improved.

Description

technical field [0001] The invention relates to a hoisting tool for ring chilled iron, which belongs to the field of hoisting tools. Background technique [0002] The roll is a common tool in metal processing and an important consumable part that determines the efficiency and rolling quality of the rolling mill. The shape, size and material of the roll must match the rolling mill and the rolled product. The conventional forming methods of rolls mainly include casting rolls and forging rolls. Casting rolls are formed by direct pouring of smelted steel or molten iron. [0003] When producing some rolled products with passes on the surface, the roll body of the section steel roll is required to have passes, and even some passes are deep. Considering the difficulty of post-processing and the need to protect the chilled layer on the surface of the roll, casting is generally used to produce such rolls with grooves, and the grooves are directly cast out. Therefore, it is necessary...

AI Technical Summary

Problems solved by technology

There are certain defects in processing the threaded holes on the cold iron: 1) After the cold iron is placed and the "T" bolts are removed, the bolt holes need to be filled with paint to prevent molten steel from entering the threaded holes, and operations are required during the filling process When personnel enter the cold mold cavity, a lot of workload is virtually increased, which is not conducive to improving production efficiency and safety in the production process; 2) After casting is completed, the threaded holes are easily damaged after being baked with high-temperature molten steel, and re-reaming is required for reuse Repeated opening and reaming will not only affect the service life of the cold iron, but also greatly slow down the production efficiency of the roll
