Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a novel multifunctional heating furnace. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet to cause it to undergo plastic deformation, its mechanical properties can be changed. 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 performed at room temperature, while hot forging is performed at a temperature higher than the recrystallization temperature of the metal billet.

[0003] When the forgings are heated by a heating furnace, metal forgings are placed in the heating chamber of the heating furnace. Multiple metal forgings are in contact with each other and piled up. Since the positions of the metal forgings in the heating furnace are fixed, the contact surfaces of the metal forgings cannot be fully heated, which in turn causes low utilization of the aperture inside the heating chamber and affects the processing efficiency of the forgings.

[0004] In the prior art, a patent document with publication number CN218015471U proposes a multifunctional heating furnace for high-precision metal forgings, which solves the problem that multiple metal forgings are in contact with each other and piled up in the heating furnace. Since the metal forgings are fixed in position, the contact surface of the metal forgings cannot be fully heated, and the aperture utilization rate inside the heating chamber is low, which affects the processing efficiency of the forgings. The multifunctional heating furnace comprises a heating furnace body, one side of which is rotatably connected to a door body, the inner wall of the heating furnace body is symmetrically provided with heating lamps, the interior of the heating furnace body is provided with a mounting column, a sealing plate is installed on one side of the mounting column, and threaded holes are provided on the mounting column and the sealing plate; this design facilitates the longitudinal arrangement of the metal forgings in the heating furnace body, solves the problem that the metal forgings are piled up on the inner bottom of the heating furnace body and are not moved, resulting in uneven heating of the contact surface, and improves the longitudinal utilization rate of the internal space of the heating furnace body.

[0005] Although the existing technology solves the problem of uneven heating of metal forgings, in actual working process, there will still be problems such as insufficient external temperature leading to poor heating effect. At the same time, the heat after heating cannot be reused, which wastes resources. Utility Model Content

[0006] In view of the shortcomings existing in the above-mentioned problems, the utility model provides a new multifunctional heating furnace, which is provided with two groups of structures and one group of circulating hot air structures.
