Description

Technical Field

[0001] The utility model relates to the technical field of automobile spring steel wire production, in particular to an annealing device for automobile spring steel wire production. Background Art

[0002] Automobile spring steel wire is a kind of steel wire used to make springs or steel wire profiles. The stress relief annealing process of spring steel wire is to eliminate the internal stress generated in the spring during the coiling process, ensure the stability of the outer diameter and number of turns when the spring is cut, reduce the degree of quenching and heating deformation, improve the performance of the spring steel wire or prepare for subsequent heat treatment.

[0003] In the prior art, an authorized patent with announcement number CN218521307U discloses a spring steel wire annealing production device, including a device body, a heat-saturating assembly including a heating coil, a fan, a duct and an air jet pipe is arranged inside the device body, a mounting plate is installed on the right side of the device body, and a transition duct including a baffle, an inner guide roller and an outer guide roller for slowing down the air flow speed is installed on the right side of the mounting plate. The heating coils are arranged in a circular array to make the temperature in the heat-saturating assembly uniform, and the hot air is transported to the air jet pipe through the fan through the U-shaped duct, and is guided out from several nozzles on the air jet pipe to be blown to the spring steel wire in the device body, so as to realize the recycling of heat energy, and the hot air is made to pass through the cross-distributed and overlapping areas of the baffle through the baffle to increase the distance of the hot air flow, and the multiple inner guide rollers and outer guide rollers make the spring steel wire as a whole "S"-shaped, so that the hot air is fully in contact with the spring steel wire and the heating is more uniform.

[0004] However, the above technical solution still has the following shortcomings when in use: the above device heats the spring steel wire by blowing the spring steel wire through a plurality of nozzles on the air jet pipe, which results in poor heating uniformity of the spring steel wire. The surface of the spring steel wire close to the nozzle is heated more than the surface far from the nozzle, resulting in poor annealing effect of the spring steel wire. In this regard, we propose an annealing device for automobile spring steel wire production to solve the above problems. Utility Model Content
