[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet.

[0003] For example, the patent document with the announcement number CN 221397947 U discloses a heat treatment device for improving the cooling uniformity of plate forgings. It includes: a cooling transfer tool and a loading rack, wherein the cooling transfer tool includes a hanging part and a load-bearing part; the hanging part includes a hanging ring, two sets of soft chains and a square steel mouth frame, one end of a set of soft chains is respectively fixed to the upper end surface of the square steel mouth frame, and the other end of a set of soft chains is connected to the hanging ring; the load-bearing part includes two load-bearing rods, and the two load-bearing rods are provided with a plurality of corresponding stoppers perpendicular to the axis of the load-bearing rods; two adjacent stoppers are used to ensure the vertical hanging of plate forgings; one end of another set of soft chains is respectively fixed to the lower end surface of the square steel mouth frame, and the other end of another set of soft chains is connected to the load-bearing rod; the loading rack includes a supporting surface and a plurality of longitudinal beams arranged on the supporting surface, and two adjacent longitudinal beams are used to ensure the vertical placement of the forgings.

[0004] However, when this structure is used for cooling forgings, due to the limitations of its own structure, it is often only possible to perform simple unidirectional wind heat dissipation operations on the forgings, and it is impossible to perform all-round and efficient heat dissipation operations on the forgings. It is very easy for uneven heat dissipation to affect the quality of the final forging products. At the same time, the equipment cannot perform efficient loading and unloading docking operations when cooling forgings, and cannot meet daily use needs. Therefore, it is urgent to design a heat treatment device that improves the uniformity of forging cooling to solve the above problems. Utility Model Content

At the same time, the equipment cannot perform efficient loading and unloading docking operations when cooling forgings, and cannot meet daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a heat treatment device for improving the cooling uniformity of forgings, comprising a cooling ring cover, a driving roller is arranged at the top of the cooling ring cover, driving gear rings are arranged at the front and rear ends of the cooling ring cover, a rotating wind cover is movably connected to the interior of the cooling ring cover through the driving gear rings at both ends, and ventilation grilles are arranged on both sides of the inner wall of the rotating wind cover;

[0010] Preferably, both ends of the cooling ring cover are movably connected with sealing seats, and a heat dissipating turbofan is arranged inside the sealing seat.

[0011] Preferably, a cooling rack is fixedly connected between the two groups of sealing seats, and a sealing baffle is provided on the side of the cooling rack.

[0012] Preferably, side fan assemblies are provided on both sides of the cooling ring cover, and a ventilation valve is provided at the center of the side of the side fan assembly.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

In actual use, the forgings to be cooled are first placed in the cooling rack between the sealing seats and sealed and protected by the sealing baffles on the sides. At this time, the cooling rack can be placed in its entirety inside the cooling ring cover, and the heat dissipation turbofans inside the sealing seats at both ends of the cooling rack can be started on a daily basis.

[0015] The heat treatment device for improving the cooling uniformity of forgings further improves the overall use effect of the equipment by arranging a cooling ring cover, a base frame, a driving motor, a reciprocating screw, a limiting slide groove, a limiting sleeve, a telescopic pull rod, a limiting bracket and a sealing seat.
