Description

Technical Field

[0001] This utility model relates to the field of annealing furnace cooling devices, specifically an annealing furnace cooling device. Background Technology

[0002] The annealing furnace cooling device is used to control the temperature inside the annealing furnace. An annealing furnace is a metal heat treatment process in which metal parts are placed in different annealing furnaces, slowly heated to a certain temperature, held at that temperature for a period of time, and then cooled at a suitable rate (usually natural cooling, sometimes controlled cooling). The purpose is to soften materials or workpieces that have undergone casting, forging, welding, or machining, reduce hardness, improve plasticity and toughness, homogenize chemical composition, remove residual stress, or obtain the desired physical properties.

[0003] For example, the authorized patent with publication number CN219470101U (annealing furnace cooling device): The annealing furnace cooling device includes a furnace body, a heating barrel is fixedly installed inside the furnace body, an exhaust fan is fixedly connected inside the heating barrel, an air supply pipe is fixedly connected to the bottom of the furnace body, an air supply ring is fixedly connected to the end of the air supply pipe away from the furnace body, the air supply pipe and the air supply ring are internally interconnected, the air supply pipe and the interior of the furnace body are interconnected, and blowers are fixedly installed on both sides of the air supply ring. The annealing furnace cooling device drives the gear and the gear ring meshing with the gear to rotate through the output shaft of the motor. The external gear inside the positioning protective shell rotates simultaneously under the circumferential motion of the gear ring, thus driving the transmission rod to rotate. The rotation of the transmission rod causes the bevel gear to drive the telescopic rod to rotate. The rotation of the telescopic rod drives the clamping arm to rotate, thus driving the workpiece to rotate and flip, thereby making it quickly and evenly heated or cooled for annealing.

[0004] The aforementioned existing annealing furnace uses a cylindrical, enclosed design, which limits its feeding process and makes it impossible to add workpieces of different shapes. Furthermore, the cooling mechanism is integrated with the annealing furnace, making assembly between the two inconvenient. The use of a single cooling control method results in uneven cooling and affects cooling efficiency. Utility Model Content
