[ Background Art ] The high-strength bolt connection is used as one of the most widely applied connection modes in ships, and has the advantages of simple construction, detachability, good stress, fatigue resistance and the like. Due to the special requirements of the ship design, the high-strength connection of the structure is realized through the high-strength bolts, and the structural strength performance can be still maintained under the continuous tension, shearing force and bending force. Therefore, the high-strength bolts for ships are required to be endowed with physical and chemical performance indexes which are more suitable for the application scene by heat treatment. Heat treatment refers to a metal heat processing process in which a material is heated, maintained and cooled in a solid state to obtain a desired structure and performance, and one of the important processes in machine fabrication during the metal heat treatment generally does not change the shape and overall chemical composition of the workpiece compared with other processes, but rather imparts or improves co-constructed service performance by changing the microstructure within the workpiece or changing the chemical composition of the surface of the workpiece. The prior high-strength bolt heat treatment feeding mode adopts manual feeding and machine semiautomatic feeding, the manual feeding mode can place bolts on a mounting plate or a mesh belt, the manual efficiency is low although the bolts are prevented from being piled up in the heat treatment process, the machine semiautomatic feeding mode is easy to lead the bolts to be piled up, the local heat treatment effect in the heat treatment process cannot be expected, and the quality problem is caused, so that in order to solve the problems, application number 202120503059.8 discloses a wind power blade high-strength bolt heat treatment feeding device which has single function and only has the feeding function, and the heat treatment furnace discharging is still realized by adopting the manual or some crude semiautomatic machine discharging mode.
