Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a flange quenching machine capable of rapidly dissipating heat. Background Art

[0002] Flange is a part that connects shafts and is often used between pipe ends. During the production process of flanges, it needs to be quenched. This step is crucial and directly affects the quality of the final product. At present, flange quenching is mainly carried out by flange quenching machine, which is to put the workpiece into the quenching machine and heat it above the critical point. The quenching temperature is maintained for a period of time, and then the workpiece is quickly taken out of the furnace and put into the quenching liquid for quenching. The existing quenching machine has limited heat dissipation effect, resulting in a long wait time before the flange can be taken out. Therefore, we have launched a flange quenching machine that can quickly dissipate heat.

[0003] The existing patent (publication number: CN220564672U) discloses a flange quenching furnace with rapid heat dissipation, including a furnace body, a quenching chamber and a material taking device. The furnace body is a well-type structure, and a quenching chamber is opened inside the furnace body. The outer wall of the furnace body is provided with a heat-conducting outer wall around the outer wall, and an external heat sink is provided on the outer side of the heat-conducting outer wall. The inner embedded internal guide pipe of the heat-conducting outer wall, the bottom of the quenching chamber is provided with a coolant storage chamber, and the coolant in the coolant storage chamber is pumped into the coolant flow chamber by a liquid pump. The material taking device is composed of an electromagnetic suction cover plate, a hanging line, a winch, a rotary drive and a column. The flange quenching furnace with rapid heat dissipation is provided with a heat-conducting outer wall, a built-in guide pipe, a liquid pump, a coolant flow chamber, a coolant storage chamber and a material taking device on the basis of the quenching chamber. The liquid is pumped into the coolant flow chamber by the liquid pump, and the flange quenching furnace is able to quickly dissipate heat by circulating and discharging in the built-in guide pipe. The existing technology has the following problems: 1. The existing quenching furnace relies on the coolant in the guide tube inside the heat-conducting outer wall for rapid cooling, but the temperature of the coolant will gradually increase during the long-term heat dissipation process, resulting in a decrease in the heat dissipation effect; 2. The existing quenching machine only relies on the heat exchange between the quenching liquid and the coolant to dissipate the heat of the quenching liquid. The heat dissipation method is single and the heat dissipation effect needs to be improved. Utility Model Content

When the motor 401 is started, it can drive the first rotating shaft 305 to rotate through the first main pulley 308, the first secondary pulley 306 and the first transmission belt 307. When the first rotating shaft 305 rotates, it drives the impeller 304 in the pump casing 303 to rotate, and the coolant in the front heat exchange chamber 2 is extracted, and the coolant is transported to the heat exchange chamber 2 on the rear side through the second pipe 302. Because the second pipe 302 is a spiral structure with a long stroke, the coolant can dissipate a large amount of heat when being transported in the second pipe 302, thereby cooling the coolant and avoiding the increase of the coolant temperature due to long-term heat exchange, which reduces the heat dissipation effect of the quenching pool 1. At the same time, the quenching liquid in the quenching pool 1 can flow into the strip port 6, and the heat is exchanged with the coolant in the heat exchange chamber 2 through the heat exchange fins 5, thereby achieving rapid cooling of the quenching liquid.

At the same time, the quenching liquid in the quenching pool 1 can flow into the strip port 6, and the heat is exchanged with the coolant in the heat exchange chamber 2 through the heat exchange fins 5, so as to achieve rapid cooling of the quenching liquid.
