Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and more specifically, to an aluminum alloy quenching furnace. Background Technology

[0002] Quenching is a metal heat treatment process in which metal parts are heated to a suitable temperature and held for a period of time, then rapidly immersed in a quenching medium to cool them quickly. Commonly used quenching media include brine, water, and mineral oil. Quenching can significantly improve the strength, hardness, wear resistance, fatigue strength, and toughness of metals, thereby meeting the different usage requirements of various mechanical parts and tools. Quenching can also satisfy the special physical and chemical properties of certain special metal materials, such as ferromagnetism and corrosion resistance. For example, an existing patent, "A Quenching Furnace for Convenient Feeding of Aluminum Alloys" (patent number: CN211947126U), discloses a quenching furnace for convenient feeding. However, after the aluminum alloy has been heated to a high temperature, it is not possible to quickly place the metal parts into the quenching medium. During the handling process, the temperature of the metal parts drops, resulting in poor quenching effect. Furthermore, the existing quenching furnace body has poor sealing of the opening and closing plates, leading to temperature leakage within the furnace body and affecting the heating of the metal parts. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an aluminum alloy quenching furnace to solve the problems of temperature drop of metal parts during the handling process of existing aluminum alloy quenching furnaces, resulting in poor quenching effect and poor sealing of the opening and closing plates of the furnace body.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an aluminum alloy quenching furnace, including a heating device and a cooling device, the heating device including a furnace body and a sealing mechanism, the furnace body having an opening at the bottom, a lifting mechanism being provided inside the furnace body, the lifting mechanism including a material rack that can move up and down, the sealing mechanism including a driving hydraulic cylinder, a first slide rail, a trolley, a furnace door and a lifting hydraulic cylinder, the first slide rail being located below the furnace body, the driving hydraulic cylinder being connected to the trolley, the lifting hydraulic cylinder being mounted on the trolley, and the lifting hydraulic cylinder being connected to the furnace door; the cooling device including a quenching tank located below the furnace body, the quenching tank being filled with coolant.

[0005] Furthermore, the furnace body is equipped with an air guide plate, a heater, and a circulating fan. The air guide plate has air guide holes, the heater is installed on the outside of the air guide plate, and the circulating fan is installed on the top of the furnace body.

[0006] Furthermore, a second slide rail is provided on the cold quenching tank, a slide plate is installed on the second slide rail, and a drive reduction motor is installed on the slide plate.

[0007] Furthermore, the lifting mechanism further includes a lifting hydraulic cylinder and a sprocket installed on the outer wall of the furnace body. The piston rod of the lifting hydraulic cylinder is provided with a chain, and the other end of the chain is provided with a hook. The chain wraps around the sprocket, and the hook hooks onto the material rack.

[0008] Furthermore, a circulating water pump is installed on one side of the quenching tank.

[0009] Furthermore, a limiting block is further provided at the bottom of the furnace body.

[0010] The beneficial effects of this utility model are:

[0011] This utility model discloses an aluminum alloy quenching furnace, comprising a heating device and a cooling device. The heating device includes a furnace body and a sealing mechanism. The furnace body has an opening at the bottom, and a lifting mechanism is installed inside the furnace body. The lifting mechanism includes a vertically movable material rack. The sealing mechanism includes a driving hydraulic cylinder, a first slide rail, a trolley, a furnace door, and a lifting hydraulic cylinder. The first slide rail is located below the furnace body, the driving hydraulic cylinder is connected to the trolley, and the lifting hydraulic cylinder is mounted on the trolley and connected to the furnace door. The cooling device includes a cold quenching tank located below the furnace body, filled with coolant. In use, metal parts are placed on the material rack, and the lifting mechanism raises the rack into the furnace body.

After the metal parts are heated, the furnace door is opened, and the lifting mechanism is used to quickly drop the material rack into the cold quenching tank for cooling. The furnace door presses tightly against the furnace body opening to prevent heat loss and to avoid temperature drops in the metal parts caused by handling after heating, thus improving the quenching quality of the metal parts.

The heater 102 is installed on the outside of the air guide plate 101. The circulating fan 103 is installed on the top of the furnace body 10. The heat generated by the heater 102 enters the interior through the air guide holes via the circulating fan 103 to heat the metal parts placed in the air guide plate 101.

[0026] Please refer to Figure 1 A lifting mechanism 11 is installed inside the furnace body 10. The lifting mechanism 11 includes a material rack 115 that can move up and down. Specifically, the lifting mechanism 11 includes a lifting hydraulic cylinder 111 and a sprocket 112 installed on the outer wall of the furnace body 10.

The end with the hook 114 is placed inside the furnace body 10. The hook 114 hooks the material rack 115. The lifting hydraulic cylinder 111 is controlled to drive the chain 113 to rotate around the sprocket 112, thereby driving the material rack 115 hooked by the hook 114 to move up and down. The structure of the lifting hydraulic cylinder 111 and the chain 113 makes the whole structure strong and can quickly put the heated metal parts of the material rack 115 into the coolant.

[0027] Please refer to Figure 1-4 The sealing mechanism 20 includes a driving hydraulic cylinder 205, a first slide rail 201, a trolley 202, a furnace door 203, and a lifting hydraulic cylinder 204.

The driving hydraulic cylinder 205 is connected to the trolley 202, and the lifting hydraulic cylinder 204 is mounted on the trolley 202 and connected to the furnace door 203. Specifically, when it is necessary to close the furnace door 203, the driving hydraulic cylinder 205 is controlled to move the trolley 202 along the first slide rail 201 to the bottom of the furnace body 10, and then the lifting hydraulic cylinder 204 is controlled to push the furnace door 203 upward to seal the opening of the furnace body 10, thereby sealing the furnace body 10. When it is necessary to open the furnace door 203, the lifting cylinder is first controlled to lower the furnace door 203, and then the driving hydraulic cylinder 205 is controlled to move the furnace door 203 away, thus automatically controlling the opening and closing of the furnace door 203. Furthermore, a limiting block is further provided at the bottom of the furnace body 10.

The quenching tank 30 is filled with coolant, and the material rack 115 is placed into the coolant via the lifting mechanism 11 for cooling treatment. A circulating water pump 303 is installed on one side of the quenching tank 30, which keeps the coolant in the quenching tank 30 flowing, thus keeping the coolant temperature low.

[0029] Please refer to Figure 1-4A second slide rail 301 is further provided on the cold quenching tank 30, and a slide plate 302 is installed on the second slide rail 301. A drive reduction motor is installed on the slide plate 302. Specifically, the drive reduction motor is controlled to move the slide plate 302 along the second slide rail 301 to above the cold quenching tank 30. The lifting mechanism 11 places the cooled material rack 115 and its metal parts on the slide plate 302. The drive reduction motor is then controlled to move the slide plate 302 along the second slide rail 301 from below the furnace body 10, thus achieving automatic unloading.
