Connection push rod for hot rolling and machining method thereof

The invention belongs to the technical field of metal rolling molding tools, and particularly relates to a connection push rod for hot rolling and a machine method thereof. The connection push rod for hot rolling includes a tail handle, a first connection rod, a second connection rod, and a push rod body. The beneficial effects of the invention are that the structure and form are easy to change, the working efficiency is high, the precision of the connection push rod is high, a rotation rolling process is more stable, and the strength is more reliable; the connection push rod can meet the demand of high-level rolling precision; components in a steel tube blank material can greatly improve the hardness of the push rod; a multi-time tempering and quenching machining method can greatly improve the hardness of the push rod too; and the connection push rod is high in precision, is excellent in mechanical rotation performance, is high in mechanical strength, is scientific and reasonable in connection ports, and can
