Description

Technical Field

[0001] This utility model belongs to the field of heating furnace technology, specifically relating to a bottom-discharge aluminum rod mold furnace. Background Technology

[0002] An aluminum rod die furnace is a heating furnace used to heat aluminum rods before extrusion. The aluminum rods are heated to a set temperature inside the furnace to soften them, and then sent to the extrusion die for extrusion molding. Therefore, compared with conventional heating furnaces, aluminum rod die furnaces need to be opened frequently for feeding. Conventional heating furnaces lose a lot of heat due to the frequent opening and closing of the furnace door during the heating process. At the same time, aluminum rods need to be fed in and out, and the feeding efficiency of conventional heating furnaces is low, which further aggravates the heat loss of the heating furnace.

[0003] To address this issue, we designed a bottom-discharge aluminum rod mold furnace to provide an alternative technical solution. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom-discharge aluminum rod mold furnace to solve the problems mentioned in the background art regarding the use of existing heating furnaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom-exit aluminum rod mold furnace, comprising an upper furnace body and a bottom removal mechanism. The upper furnace body contains a heating chamber, and the heating chamber contains a high-frequency electric heating tube. The bottom removal mechanism is located below the heating chamber and includes a bottom groove. A set of horizontally arranged sliding tracks is arranged inside the bottom groove. A lifting frame is mounted on the sliding tracks. The lifting frame, from top to bottom, sequentially comprises a material support, a sealing plate, a lifting device, and a sliding device. The material support is located at the top of the lifting frame and is fed into the heating chamber via the lifting device. The sealing plate is located below the material support for sealing connection with the bottom of the heating chamber. The lifting device is located below the sealing plate to move the sealing plate and the material support vertically. The sliding device is located on the sliding tracks to move the lifting frame horizontally.

[0006] Preferably, the upper furnace body is provided with a heat insulation layer on the outside of the heating chamber, and the bottom removal mechanism is provided with heat insulation plates on both sides.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-2A bottom-exit aluminum rod mold furnace includes an upper furnace body and a bottom removal mechanism. The upper furnace body is provided with a heating chamber, and a high-frequency electric heating tube is installed inside the heating chamber. The bottom removal mechanism is located below the heating chamber and includes a bottom groove. A set of horizontally arranged sliding tracks is installed inside the bottom groove. A lifting frame is installed on the sliding tracks. The lifting frame is provided with a material support, a sealing plate, a lifting device, and a sliding device in sequence from top to bottom. The material support is located at the top of the lifting frame and is sent into the heating chamber through the lifting device. The sealing plate is located on the lower side of the material support for sealing connection with the bottom of the heating chamber. The lifting device is located on the lower side of the sealing plate for driving the sealing plate and the material support to move up and down. The sliding device is located on the sliding track for driving the sliding lifting frame to slide.

[0018] This solution proposes a bottom-discharge aluminum rod heating furnace. The heating chamber of the aluminum rod heating furnace is closed at the top and on the left and right sides. The aluminum rod is fed and discharged through the discharge port at the bottom, which is driven by the lifting and shifting frame. During heating, the aluminum rod is sent into the heating chamber of the furnace body under the support of the lifting and shifting frame for heating and temperature rise. After the temperature reaches the set temperature, the lifting device drives the aluminum rod to move downward, thereby removing the heated aluminum rod. Finally, the aluminum rod moves along the track under the drive of the sliding device to realize feeding.

[0019] In this solution, the heated aluminum rods are removed from the bottom of the heating furnace, and the heating furnace is fed out through the bottom discharge port. The heat loss is minimal throughout the process, which helps to reduce the energy consumption of the heating furnace. At the same time, the equipment is highly automated and efficient, suitable for the high-speed requirements of modern operations, thanks to the automated feeding and heating of the lifting frame and the sliding discharge. The high efficiency of automated feeding further reduces heat loss in the furnace during loading and unloading, resulting in better overall performance of the heating furnace and making it more environmentally friendly and efficient.

[0020] Furthermore, an insulation layer is provided on the outside of the heating chamber of the upper furnace body, and insulation plates are provided on both sides of the bottom removal mechanism.

[0021] Through this technical solution, the insulation layer adopts a multi-layer composite insulation structure design. The inner side of the upper furnace body is laid with a high-temperature resistant ceramic fiber layer and aerogel felt, and the outer layer is covered with a stainless steel protective plate. In other implementation defenses, a concrete insulation layer can also be used. The insulation plates equipped on both sides of the bottom removal mechanism form a barrier, thereby reducing heat loss.

[0022] Furthermore, locking devices are provided on both sides of the bottom of the heating chamber.

[0023] The locking device includes a connecting rod and cylinders on both sides. When the aluminum rod is heated in the heating chamber, the cylinders of the locking device push the connecting rod to press against the sealing plate, thereby ensuring the airtightness of the heating chamber. When the aluminum rod is discharged after heating, the locking device opens to release the locking of the lifting and shifting frame. When the aluminum rod is heated, the locking device closes to reduce heat loss.

[0024] Furthermore, a circulating fan is installed at the top of the heating chamber.

[0025] Since the high-frequency electric heating element that enables heating is located on one side, the temperature inside the heating chamber will be uneven during heating. The circulating fan at the top of the heating chamber can drive the hot air inside the heating chamber to circulate, so that the temperature inside the heating chamber remains consistent and uniform, thereby keeping the temperature of the heating furnace constant and improving the heating effect.

[0026] Furthermore, the lifting device includes a set of lifting rods and two sets of guide rods disposed on both sides of the lifting rods.

[0027] The lifting rod is used to drive the aluminum bar to move up and down, and the guide rod is used to effectively eliminate radial offset during the lifting process and ensure the accuracy control of the vertical movement trajectory. In this solution, the surfaces of the guide rod and the lifting rod are coated with a high-temperature heat insulation coating to reduce the impact of high temperature on low operating accuracy and service life.

[0028] Furthermore, the sliding device includes a bracket, inside which a drive shaft is installed, with sliding wheels at both ends of the drive shaft, and a motor for driving the drive shaft to rotate is installed on one side of the bracket.

[0029] The sliding device is driven by a motor to rotate the transmission shaft, which in turn drives the sliding wheel to slide laterally on the sliding track, thereby sending out the heated aluminum rod.

[0030] Working principle: The heating chamber of the aluminum rod heating furnace is closed at the top and left and right sides. The aluminum rod is fed and discharged through the discharge port at the bottom. The aluminum rod moves up and down under the drive of the lifting frame. During heating, the aluminum rod is sent into the heating chamber of the furnace body under the support of the lifting frame for heating. After the temperature reaches the set temperature, the lifting device moves the aluminum rod down to remove the heated aluminum rod. Finally, the aluminum rod moves along the track under the drive of the sliding device to realize feeding.
