Description

Push boat type tempering heating furnace for tempering production line Technical Field The utility model relates to the technical field of tempering heating furnaces, in particular to a push boat type tempering heating furnace for a tempering production line. Background In the processing process of the forging, the forging needs to be subjected to quenching and tempering treatment, wherein a tempering heating furnace is used. The patent publication No. CN211005489U discloses a boat pushing type tempering heating furnace for a gas heating front shaft tempering production line, which comprises a tempering heating mechanism and a tempering pushing mechanism, wherein the tempering heating mechanism is used for tempering a processed workpiece, the tempering pushing mechanism is connected with the tempering heating mechanism and arranged on a feed port of the tempering heating mechanism and used for conveying the workpiece into the tempering heating mechanism, the tempering pushing mechanism comprises a frame body, a pushing trolley and a first hydraulic cylinder, the frame body is arranged on the feed port of the tempering heating mechanism, the pushing trolley and the hydraulic cylinder are both arranged on the frame body, and the pushing trolley can slide on the frame body through the driving of the first hydraulic cylinder.
