Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile heat treatment technology, specifically relating to an aluminum rod heat treatment device. Background Technology

[0002] Aluminum alloys, as a lightweight, high-strength, and corrosion-resistant metallic material, are widely used in industrial manufacturing and construction. To obtain the final finished aluminum profiles, the aluminum rods obtained after extrusion molding usually need to undergo heat treatment. The quality of the heat treatment directly affects the quality of the finished aluminum rods. Existing technologies have proposed various solutions for heat treatment equipment for aluminum rods. For example, the utility model patent with authorization announcement number CN 221117500 U discloses an aluminum profile heat treatment device, including: a treatment box, which is equipped with a rotating mechanism, an ejection mechanism, and two closing mechanisms; the rotating mechanism includes a fixed shaft, a first motor, a sliding sleeve, a fixed plate, and multiple placement rods. The fixed shaft is rotatably installed inside the treatment box, the first motor is fixedly installed on one side of the outer wall of the treatment box, and the output shaft of the first motor is fixedly connected to one end of the fixed shaft. The sliding sleeve is slidably fitted on the fixed shaft, the fixed plate is fixedly fitted on the sliding sleeve, and the multiple placement rods are all fixedly installed on the fixed plate.

[0003] The aluminum profile heat treatment device provided by this utility model allows for the individual placement and rotation of aluminum bars, ensuring uniform heating. However, after each heat treatment cycle, the chamber door must be opened to remove the treated aluminum bars and refill with untreated bars before the next heat treatment cycle can begin. During this opening process, significant heat loss occurs within the chamber, requiring a considerable amount of time to raise the temperature to the preset level for the next heat treatment cycle, which does not meet energy-saving and emission-reduction production requirements. Therefore, it is necessary to design an aluminum bar heat treatment device that minimizes heat loss during the heat treatment process, thereby improving efficiency and reducing energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for aluminum rods to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A heat treatment apparatus for aluminum bars includes a heating furnace. One end of the heating furnace is provided with a feeding mechanism, and the other end is provided with a discharging mechanism. A material rack for supporting aluminum bars is provided inside the heating furnace. The material rack includes a main rotating shaft, which is rotatably connected to the two end walls of the heating furnace. Multiple partitions are spaced apart on the main rotating shaft, and the partitions are fixedly connected to the main rotating shaft. Multiple first through holes are provided along the circumference of the partitions, and the positions of the first through holes of the multiple partitions are corresponding. A first motor is fixedly provided outside the heating furnace, and the output shaft of the first motor is fixedly connected to the main rotating shaft.

[0007] The heating furnace has a second and a third through hole that can be opened and closed on one end wall. The position of the second through hole corresponds to the position of one of the first through holes, and the position of the third through hole corresponds to the position of the other first through hole. The heating furnace has a fourth through hole that can be opened and closed on the other end wall. The position of the fourth through hole corresponds to the position of the third through hole.

[0008] As a further improvement, the feeding mechanism includes a conveyor belt, and a guide plate is provided at the end of the conveyor belt in the conveying direction. The guide plate includes a base plate and side plates that are perpendicularly fixed to both sides of the base plate. One of the side plates is provided with a fifth through hole, the position of which corresponds to the position of the second through hole. A first guide rail is fixedly provided at the end of the guide plate. A lead screw parallel to the first guide rail is rotatably provided between the two side plates. A slide table is slidably provided on the first guide rail. A second motor is fixedly provided on the guide plate, and the output shaft of the second motor is fixedly connected to one end of the lead screw.

[0009] As a further improvement, a mounting base is fixedly connected to the slide, and the mounting base is rotatably connected to the lead screw. A baffle is rotatably connected to the top surface of the mounting base, and a boss is fixedly provided at the end of the mounting base away from the fifth through hole.

[0023] like Figure 1-6 As shown, an aluminum rod heat treatment device includes a heating furnace 1. One end of the heating furnace 1 is provided with a feeding mechanism 2, and the other end is provided with a discharging mechanism 3. The heating furnace 1 is provided with a material rack 4 for carrying aluminum rods 7. The material rack 4 includes a main rotating shaft 401, which is rotatably connected to the two end walls of the heating furnace 1. Multiple partitions 402 are spaced on the main rotating shaft 401, and the partitions 402 are fixedly connected to the main rotating shaft 401. Multiple first through holes 403 are provided along the circumference of the partitions 402, and the positions of the first through holes 403 of the multiple partitions 402 are corresponding. A first motor 5 is fixedly provided outside the heating furnace 1, and the output shaft of the first motor 5 is fixedly connected to the main rotating shaft 401.

[0024] The heating furnace 1 has a second through hole 101 and a third through hole 102 on one end wall, which can be opened and closed. The position of the second through hole 101 corresponds to the position of one of the first through holes 403, and the position of the third through hole 102 corresponds to the position of the other first through hole 403. The heating furnace 1 has a fourth through hole 103 on the other end wall, which can be opened and closed. The position of the fourth through hole 103 corresponds to the position of the third through hole 102. Specifically, the feeding mechanism 2 places the aluminum rod 7 into the corresponding first through hole 403 of the material rack 4 through the second through hole 101. The first motor 5 drives the main shaft 401 and the material rack 4 to rotate at a certain angle, and the feeding mechanism 2 places the aluminum rod 7 into another unused first through hole 403. This cycle continues until all the first through holes 403 are filled with aluminum rods 7. Then, the second through hole 101 is closed, and the aluminum rod 7 can be heat-treated. After heat treatment, the unloading mechanism 3 removes the heat-treated aluminum rod 7 from the heating furnace 1 through the fourth through hole 103. This allows for continuous and alternating loading and unloading operations, enabling the loading and unloading of the aluminum rod 7 without opening the entire furnace door of the heating furnace 1. Since the diameters of the second through hole 101, the third through hole 102, and the fourth through hole 103 all match the outer diameter of the aluminum rod 7 and are much smaller than the dimensions of the end face of the heating furnace 1, the loading and unloading process effectively reduces heat loss within the heating furnace 1.

[0025] In this embodiment, the feeding mechanism 2 includes a conveyor belt 201, which carries and transports aluminum rods 7 that have not undergone heat treatment. A guide plate 202 is provided at the end of the conveyor belt 201 in the conveying direction. The guide plate 202 includes a base plate 2021 and side plates 2022 that are vertically fixedly connected to both sides of the base plate 2021. The guide plate 202 guides and limits the movement trajectory of the aluminum rods 7. One of the side plates 2022 has a fifth through hole 2023, the position of which corresponds to the position of the second through hole 101. A first guide rail 203 is fixedly provided at the end of the guide plate 202. A lead screw 204, parallel to the first guide rail 203, is rotatably connected between the two side plates 2022. A slide table 205 slides on the guide rail. A second motor 206 is fixedly provided on the guide plate 202, and the output shaft of the second motor 206 is fixedly connected to one end of the lead screw 204. The second motor 206 drives the lead screw 204 to rotate, and the lead screw 204 drives the slide table 205 to move along the first guide rail 203.

[0026] In this embodiment, a mounting base 207 is fixedly connected to the slide table 205. The mounting base 207 is threadedly rotatably connected to the lead screw 204. A baffle 208 is rotatably connected to the top surface of the mounting base 207. A boss 209 is fixedly provided on one end of the mounting base 207 away from the fifth through hole 2023. The boss 209 limits the rotation angle of the baffle 208 and provides it with force support. A spring 210 is connected between the boss 209 and the baffle 208, and the spring 210 is in a stretched state. Figure 4 As shown, the end face of the baffle 208 without the spring 210 abuts against the end face of the first aluminum rod 7. When the slide table 205 moves the mounting base 207, the baffle 208 pushes the first aluminum rod 7 to move and pushes it into the first through hole 403 of the material rack 4 through the second through hole 101. At this time, the second aluminum rod 7 reaches the end of the guide plate 202 under the action of gravity. The second motor 206 rotates in the opposite direction, and the slide table 205 moves the mounting base 207 in the opposite direction. During this process, after the end face of the baffle 208 with the spring 210 contacts the surface of the second aluminum rod 7, as... Figure 4 As shown, when the baffle 208 rotates counterclockwise, the spring 210 is further stretched until the baffle 208 moves to the other end of the second aluminum rod 7. Under the action of the spring 210, the baffle 208 returns to its original position. When the second motor 206 rotates forward again, the baffle 208 pushes the second aluminum rod 7 into another first through hole 403 of the material rack 4.

[0027] In this embodiment, a first cylinder 6 is fixedly installed on the outside of the heating furnace 1. The output end of the first cylinder 6 corresponds to the position of the third through hole 102. When the first cylinder 6 extends, it can push the heat-treated aluminum rod 7 out of the fourth through hole 103 a certain distance.

[0028] In this embodiment, the unloading mechanism 3 includes a mounting frame 301. The mounting frame 301 includes a vertically arranged side arm 3011 and a crossbeam 3012 fixedly connected to the side arm 3011. The crossbeam 3012 is provided with a horizontally arranged second guide rail 302 and a rack 303 arranged parallel to the second guide rail 302. A first mounting plate 304 is slidably connected to the second guide rail 302. A third motor 305 is fixedly mounted on the first mounting plate 304. A gear 306 is fixedly mounted on the output shaft of the third motor 305. The gear 306 meshes with the rack 303. The third motor 305 drives the gear 306 to rotate, and the gear 306 drives the first mounting plate 304 to slide along the second guide rail 302.

[0029] In this embodiment, a second cylinder 307 is fixedly mounted on the first mounting plate 304, and a second mounting plate 308 is fixedly mounted on the output end of the second cylinder 307. A pneumatic gripper 309 for gripping the aluminum rod 7 is fixedly mounted on the second mounting plate 308. When the second cylinder 307 extends and retracts, it drives the second mounting plate 308 to move up and down. After the pneumatic gripper 309 grips the aluminum rod 7 pushed out by the first cylinder 6, the second motor 206 starts and moves the first mounting plate 304 along the second guide rail 302 until the aluminum rod 7 is completely removed and then transferred to the next process.

[0030] In this embodiment, the operator places the untreated aluminum rods 7 onto the conveyor belt 201 one by one. The second through hole 101 is opened, and the second motor 206 drives the mounting base 207 and the baffle 208 to push the aluminum rods 7 one by one into the first through hole 403. Then, the second through hole 101 is closed and the aluminum rods 7 are heat-treated. After the heat treatment is completed, the third through hole 102 is opened, the first cylinder 6 extends and pushes the aluminum rods 7 out a certain distance. The pneumatic gripper 309 removes all the aluminum rods 7, and then the material can be reloaded for the next heat treatment operation.
