The spheroidizing annealing device comprises an annealing furnace, an annealing furnace upper cover, a furnace cover lifting device, an in-furnace heater, a gantry lifting device and an annealing furnace movable inner container, wherein the annealing furnace is a tank body with an upward opening, the annealing furnace upper cover capable of being matched with the annealing furnace upper cover is arranged at the opening in the upper end of the annealing furnace, the annealing furnace upper cover is detachably connected with the annealing furnace, the furnace cover lifting device capable of being matched with the annealing furnace upper cover is arranged on the annealing furnace upper cover, and the lower end of the furnace cover lifting device is fixedly connected with the side edge of the annealing furnace. The annealing furnace movable inner container capable of moving up and down and the gantry lifting device capable of being matched with the annealing furnace movable inner container are arranged in the annealing furnace, the annealing furnace movable inner container is driven by the gantry lifting device to ascend and descend up and down, discharging and taking in the annealing furnace can be facilitated, the annealing efficiency is improved, the annealing quality is improved, thelabor intensity of workers is reduced, and the safety is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of fastener production, in particular to the technical field of fastener wire spheroidizing annealing devices. 【Background technique】 [0002] Fasteners are also called standard parts in the market, which is a general term for a type of mechanical parts used when two or more parts are fastened and connected into a whole. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts and are in great demand. The raw materials of fasteners are generally wire rods. In order to improve the plasticity and toughness of wire rods, the raw materials of wire rods are usually spheroidized and annealed before the production of fasteners. Spheroidizing annealing is an annealing to spheroidize carbides in steel to obtain a structure of spherical or granular carbi...

AI Technical Summary

Problems solved by technology

When cutting workpieces with spheroidized structures, the tool can avoid cutting hard and brittle cementite, and pass through soft ferrite, thus prolonging the service life of the tool and improving the machinability of steel, but Most of the existing spheroidizing annealing furnaces are bell-type. During the spheroidizing annealing process, it is inconvenient to discharge and take out materials. It is laborious to take out materials, the labor intensity of workers is high, and the efficiency is low.
