Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, specifically to an aluminum rod heating furnace for aluminum alloy processing. Background Technology

[0002] Aluminum alloys are widely used in various industrial fields such as aerospace, automotive, rail transportation, construction, and packaging due to their advantages such as low density, high strength, and good corrosion resistance. During the extrusion, forging, and heat treatment of aluminum alloy profiles, preheating of the aluminum rods is usually required to achieve a specific internal temperature distribution to meet the requirements of subsequent forming processes. In existing technologies, aluminum rod heating mainly relies on structures such as gas-fired furnaces, electric furnaces, or induction heating devices. The primary purpose is to heat the aluminum rods to the temperature range required for extrusion or heat treatment (e.g., 400°C to 550°C) and to achieve axial temperature uniformity and cross-sectional temperature difference control as much as possible.

[0003] A search revealed that utility model patent CN213120032U discloses an aluminum rod heating furnace for processing aluminum alloy profiles. The furnace positions each aluminum rod so that it can be suspended in the furnace body, improving the heating effect and preventing the aluminum rods from touching and colliding, thus avoiding deformation.

[0004] In the above scheme, the aluminum rod cannot maintain its central rotation during the heating process, which easily leads to uneven heating. After heating, it is still restricted by the clamping structure before transfer or discharge, making it difficult to move smoothly and requiring multiple manual interventions. Due to the difference in diameter, the aluminum rod axis deviates from the center of the heating chamber entrance in the height direction during the process of rolling from the feeding hopper into the heating chamber. In particular, when the center of the aluminum rod is higher than the center of the entrance, the traditional rigid support structure is difficult to adjust automatically and requires manual intervention or forced insertion, which affects the centering accuracy and processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum rod heating furnace for aluminum alloy processing, so as to solve the problems mentioned in the background art.

[0006] The main technical problem solved by this invention is:

[0007] The aluminum rod cannot maintain its central rotation during the heating process, which easily leads to uneven heating. After heating is completed, it is still restricted by the clamping structure before being transferred or discharged, making it impossible to move smoothly and requiring multiple manual interventions.

[0008] Due to differences in diameter, the aluminum rods deviate in height from the center of the heating chamber entrance as they roll from the feeding hopper into the heating chamber. In particular, when the center of the aluminum rod is higher than the center of the entrance, the traditional rigid support structure is difficult to adjust automatically and requires manual intervention or forced insertion, which affects the centering accuracy and processing efficiency.

[0009] This invention can be achieved through the following technical solutions:

[0010] A heating furnace for aluminum rods used in aluminum alloy processing includes a furnace body, a feeding box, and a discharging bin that are interconnected, with the feeding box and discharging bin respectively located on both sides of the furnace body;

[0011] Several heating chambers are located inside the furnace body;

[0012] Two heating plates are symmetrically installed in each heating chamber;

[0013] The inlet is located on one side surface of each heating chamber;

[0014] The outlet is located on the opposite side surface of each heating chamber, and the outlet is lower than the feed height of the inlet;

[0015] A clamping and rotating assembly is used to limit and slide the aluminum rod inside each heating chamber, which includes clamping seat one and clamping seat two that are close to or far apart from each other.

[0016] A support and transfer unit that moves vertically is provided between clamp one and clamp two. The support and transfer unit includes a roller seat. The top of the roller seat is V-shaped, and multiple drive rollers are rotatably mounted on the V-shaped surface of the top of the roller seat.

[0017] The clamping base is provided with an active clamping rotation unit; the active clamping rotation unit includes a rotating seat rotatably disposed in the clamping base, and a plurality of limiting seats that simultaneously slide along the corresponding slide rails on one side surface of the rotating seat, and a pressure roller is fixed on each limiting seat that contacts one end surface of the aluminum rod.

[0018] The outer surface edge of the rotating seat is provided with a toothed ring, and the surface of the clamp is provided with a drive gear driven by a servo motor and meshing with the toothed ring;

[0019] The clamping seat 2 has a driven clamping rotation unit inside. The driven clamping rotation unit includes a rotating ring that is rotatably arranged with the clamping seat 2. The rotating ring has multiple electric push rods 2 inside. The pushing end of each electric push rod 2 is connected to a pressure roller 2 that contacts the surface of the other end of the aluminum rod.

[0020] A further technical improvement of the present invention is that an electric push rod for lifting and lowering the roller seat is installed on the inner bottom surface of each heating chamber;

[0021] As the roller seat rises, the aluminum rod smoothly enters the drive rollers on both sides and eventually reaches the interior of clamp one;

[0022] As the roller seat descends, the aluminum rod enters the outlet under the pushing force of the friction between the aluminum rod and the drive rollers on both sides.

[0023] A further technical improvement of the present invention is that the distance between the two heating plates in each heating chamber is greater than the width of the roller seat.

[0024] A further technical improvement of the present invention is that: a sealing plate is provided at the top of the inner cavity of each heating chamber, and a moving groove is provided on both sides of the sealing plate; and a transmission screw driven by a dual-axis motor is provided above the sealing plate, and two transmission screws are provided.

[0025] One drive screw is threadedly connected to one clamp, and the other drive screw is threadedly connected to another clamp.

[0026] Clamp one and clamp two slide along their respective motion grooves.

[0027] A further technical improvement of the present invention is that: the inner wall surface of the heating chamber is provided with an outwardly protruding protrusion, which slides in contact with clamping seat one and clamping seat two respectively.

[0028] A further technical improvement of the present invention is that: the surface of the rotating seat is provided with a slot for the aluminum rod to enter, the center of the slot is provided with an inwardly recessed cavity, and a plurality of driven bevel gears driven by the meshing of the driving bevel gear are installed in the cavity, and the end of each driven bevel gear is fixed with a transmission screw that rotates in the corresponding slide.

[0029] The transmission screw two is threadedly connected to the corresponding limit seat.

[0030] A further technical improvement of the present invention is that: both sides of the feeding box are provided with feeding channels, and the inside of the feeding box is provided with a feeding chamber corresponding to the heating chamber, with the inlet located at the connection between each feeding chamber and the heating chamber;

[0031] Each feeding hopper is equipped with a baffle that is driven by a reciprocating cylinder and blocks the feeding channel.

[0032] A further technical improvement of the present invention is that: the inner wall of the feeding hopper is provided with two symmetrical fixed seats, the upper surface of the end of the fixed seat is provided with a limiting groove, and one side of the fixed seat is slidably connected to an adaptive support unit that slides along the limiting groove;

[0033] The adaptive support unit includes a guide seat, a support seat below the guide seat, and a buffer rod extending into the support seat from the bottom of the guide seat.

[0034] The inner wall of the fixed seat is equipped with a synchronous cylinder that pushes the support to slide, and the surface of the support is equipped with a guide rod that limits the sliding within the fixed seat;

[0035] The inner wall of the feeding bin on the same side is embedded with a push rod that slides towards the inlet. The push rod is used to push aluminum bars in the feeding bin on the same side.

[0036] A further technical improvement of the present invention is that: the bottom surface of the guide seat is provided with a pushing part, and one side of the top of the guide seat is provided with a sliding plate that is limited and slidable in the limiting groove;

[0037] The fixed seat has a ramp on the side facing the support, which has the same inclination angle as the push part. The surface of the ramp has a notch for guiding the seat in.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. By setting up a clamping and rotating assembly and a supporting and transferring unit, the supporting and transferring unit is located between clamp seat one and clamp seat two. The drive roller provides support and guidance for the bottom of the aluminum rod. The aluminum rod is fed along the direction of the heating chamber and finally reaches the slot in the hole of clamp seat one. Multiple pressure rollers fix one end of the aluminum rod, and multiple pressure rollers in clamp seat two fix the other end of the aluminum rod. After the roller seat descends once, the aluminum rod rotates, making its heating more uniform, and the aluminum rod is always located at the center of rotation. Then, the fixation of the two ends of the aluminum rod is released, so that the aluminum rod moves down to contact the drive roller that descended once. At the same time, clamp seat one and clamp seat two slide along the motion groove under the drive of the corresponding transmission screw two, realizing that clamp seat one and clamp seat two move away from each other and completely separate from the two ends of the aluminum rod. The roller seat descends a second time, and the center of the aluminum rod is aligned with the center of the outlet, which facilitates the discharge of the aluminum rod.

[0040] 2. By setting an adaptive support unit, when the center of the aluminum rod deviates from the center of the inlet, the synchronous cylinder drives the support to slide along the direction of the fixed seat. The support moves smoothly under the limit of the guide rod, while simultaneously moving the upper guide seat and the slide plate as a whole. At this time, the pushing part pushes against the inclined platform, and the pushing part drives the slide plate to slide along the limiting groove. At this time, the guide seat rises and drives the buffer rod to slide at the top of the support. At the same time, the guide seat enters the notch on the surface of the inclined platform, achieving stable limiting engagement with the inclined platform. At this time, the aluminum rod supported by the two supports descends as a whole, so that the central axis of the aluminum rod is re-aligned with the center of the inlet, completing the adaptive centering support adjustment and adaptively adjusting the support height to ensure that it is aligned with the center of the inlet.

[0051] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0052] Please see Figures 1-8 As shown, the present invention provides an aluminum rod heating furnace for aluminum alloy processing, including a furnace body 1, a feeding box 2 and a discharging bin 4 that are interconnected, with the feeding box 2 and the discharging bin 4 respectively disposed on both sides of the furnace body 1;

[0053] The furnace body 1 has several heating chambers installed inside, and each heating chamber has two symmetrical heating plates 17 installed inside;

[0054] Each heating chamber has an inlet 16 on one side surface for the aluminum rod to enter centrally, and an outlet 27 on the other side surface for the aluminum rod to exit. The outlet 27 is lower than the feeding height of the inlet 16.

[0055] Each heating chamber is equipped with a sliding clamping and rotating assembly that limits the movement of the aluminum rod.

[0056] The clamping and rotating assembly includes clamp 26 and clamp 18 that are close to or far apart from each other;

[0057] A support and transfer unit that moves vertically is provided between clamp 1 26 and clamp 2 18. The support and transfer unit includes roller seat 19. The top of roller seat 19 is V-shaped, and multiple drive rollers 20 are rotatably mounted on the V-shaped surface of the top of roller seat 19.

[0058] The clamping seat 26 is provided with an active clamping rotation unit; the active clamping rotation unit includes a rotating seat 30 rotatably disposed in the clamping seat 26, and a plurality of limiting seats 32 are provided on one side surface of the rotating seat 30, which simultaneously slide along the corresponding slide rails. Each limiting seat 32 is fixed with a pressure roller 31 that contacts one end surface of the aluminum rod.

[0059] The outer surface edge of the rotating seat 30 is provided with a toothed ring, and the surface of the clamp 26 is provided with a drive gear 29 driven by a servo motor and meshing with the toothed ring;

[0060] The interior of the clamping seat 2 18 is provided with a driven clamping rotation unit. The driven clamping rotation unit includes a rotating ring 34 that is rotatably disposed with the clamping seat 2 18. The interior of the rotating ring 34 is provided with multiple electric push rods 2 35. The pushing end of each electric push rod 2 35 is connected to a pressure roller 2 36 that contacts the surface of the other end of the aluminum rod.

[0061] The aluminum rod enters through the feeding box 2 and then enters the corresponding heating chamber through the inlet 16;

[0062] Before entering the heating chamber, the multiple pressure rollers 31 and 36 in clamp 1 26 and clamp 2 18 are all in a far-away state, that is, the two ends of the aluminum rod are not restricted.

[0063] The supporting transfer unit is located between clamp 1 26 and clamp 2 18, and the drive roller 20 provides support and guidance for the bottom of the aluminum rod.

[0064] The end of the aluminum rod is pushed forward by an external force, and after passing through the rotating ring 34, it rolls through multiple drive rollers 20 set on the surface of the V-shaped roller seat 19, and finally reaches the interior of the clamp 26.

[0065] Subsequently, the active clamping and rotating unit in clamp seat 26 starts to work, that is, multiple limiting seats 32 simultaneously slide in the corresponding slide rails until the pressure roller 31 is in close contact with the end surface of the aluminum rod, fixing one end surface of the aluminum rod.

[0066] Immediately afterwards, the driven clamping and rotating unit in the clamping seat 2 18 starts to work, and multiple electric push rods 2 35 simultaneously push the corresponding pressure rollers 2 36 to make close contact with the other end surface of the aluminum rod, thus fixing the other end surface of the aluminum rod.

[0067] Then, the roller seat 19 moves down, and the aluminum rod is in a "suspended" clamping state, so that the drive roller 20 does not contact the aluminum rod, avoiding wear and interference with heating efficiency, and facilitating the rotational heating of the aluminum rod.

[0068] Then the servo motor drives the gear 29 to rotate, which in turn drives the meshing gear ring, thereby making the rotating seat 30 and the clamp 26 rotate at a constant speed.

[0069] Meanwhile, the rotating ring 34 connected to the other end of the aluminum rod rotates within the clamp 18.

[0070] When the aluminum rod rotates, the heating plates 17 on both sides heat the aluminum rod evenly to avoid local overheating. During each heating, the aluminum rod is always located in the center of rotation to ensure that the aluminum rod remains centered during the rotation heating process without deviation or shaking. This effectively disperses thermal stress and prevents the aluminum rod from bending or cracking due to local overheating, thereby improving the overall processing quality.

[0071] Afterwards, multiple pressure rollers 31 and multiple pressure rollers 36 are in an open and away state, releasing the restriction on both ends of the aluminum rod. At this time, the aluminum rod moves down from the middle and contacts the drive roller 20. Then, clamp 26 and clamp 18 move away from each other.

[0072] Finally, the roller seat 19 moves down so that the center of the aluminum rod is aligned with the center of the outlet 27;

[0073] Driven by a motor, the drive roller 20 rotates and, through friction with the bottom of the aluminum rod, directionally conveys the aluminum rod, smoothly pushing it out of the heating chamber along the outlet 27.

[0074] See Figure 4 and Figure 5 As shown, each heating chamber has an electric push rod 21 installed on the inner bottom surface to push the roller seat 19 up and down;

[0075] The electric linear actuator 21 performs segmented motion;

[0076] As the roller seat 19 rises, the aluminum rod smoothly enters the drive rollers 20 on both sides and finally reaches the interior of the clamp 26.

[0077] The roller seat 19 descends a small distance at a time, so that the drive roller 20 does not contact the aluminum rod. The cooperation of the active clamping rotation unit and the driven clamping rotation unit drives the two ends of the aluminum rod to rotate.

[0078] After the active clamping rotation unit and the driven clamping rotation unit release the restriction on both ends of the aluminum rod, the aluminum rod descends onto the drive roller 20, which has descended a short distance from the roller seat 19.

[0079] Clamp 1 26 and clamp 2 18 move away from each other and separate from both ends of the aluminum rod, while the aluminum rod moves down with roller seat 19, so that the aluminum rod is aligned with the center of outlet 27.

[0080] The roller seat 19 descends a second time, and under the force of friction between the aluminum rod and the two drive rollers 20, the aluminum rod enters the outlet 27.

[0081] See Figure 4 As shown, the distance between the two heating plates 17 in each heating chamber is greater than the width of the roller seat 19;

[0082] When the roller seat 19 rises, it will not collide with the heating plates 17 on both sides.

[0083] See Figure 5 As shown, each heating chamber has a sealing plate 22 at the top of its inner cavity, and motion grooves 24 on both sides of the sealing plate 22. There are two transmission screws 23 driven by a dual-axis motor above the sealing plate 22.

[0084] One drive screw 23 is threadedly connected to clamp 26, and the other drive screw 23 is threadedly connected to clamp 18.

[0085] Clamp 1 26 and clamp 2 18 slide along the corresponding motion groove 24 respectively.

[0086] The inner wall of the heating chamber is provided with an outwardly protruding boss 28, which slides in contact with clamp 1 26 and clamp 2 18 respectively.

[0087] Driven by a dual-axis motor, the two transmission screws 23 rotate synchronously, driving the screw-connected clamps 26 and 18 to slide horizontally along the corresponding motion grooves 24, thereby achieving precise adjustment of the clamping position.

[0088] Meanwhile, during the sliding process, clamp 1 26 and clamp 2 18 always maintain close sliding contact with the protrusion 28 on the corresponding inner wall, forming a multi-point guide support structure.

[0089] The surface of the rotating seat 30 is provided with a slot for the aluminum rod to enter. The center of the slot is provided with an inwardly recessed cavity. Multiple driven bevel gears driven by the meshing of the driving bevel gear are installed in the cavity. The end of each driven bevel gear is fixed with a transmission screw 33 that rotates in the corresponding slide.

[0090] The transmission screw 33 is threadedly connected to the corresponding limit seat 32.

[0091] Initially, clamp 1 26 and clamp 2 18 are located Figure 5 As shown, the slot in the rotating seat 30 is located directly above the boss 28;

[0092] When the aluminum rod is fed along the direction of the heating chamber, it eventually reaches the slot in the clamp 26;

[0093] Multiple pressure rollers 31 fix one end of the aluminum rod, and multiple pressure rollers 36 inside the clamp 18 fix the other end of the aluminum rod.

[0094] After the roller seat 19 descends once, the aluminum rod rotates, making the heating more uniform.

[0095] Then, the fixing of both ends of the aluminum rod is released, so that the aluminum rod moves down to contact the driving roller 20 that descends once. At the same time, the clamp 1 26 and clamp 2 18 slide along the motion groove 24 under the drive of the corresponding transmission screw 2 33, so that the clamp 1 26 and clamp 2 18 move away from each other and are completely separated from both ends of the aluminum rod.

[0096] The roller seat 19 descends twice to facilitate the discharge of aluminum rods.

[0097] See Figure 2 As shown, feeding channels 3 are provided on both sides of the feeding box 2, and the inside of the feeding box 2 is provided with a feeding chamber corresponding to the heating chamber. The inlet 16 is located at the connection between each feeding chamber and the heating chamber.

[0098] Each feeding hopper is equipped with a baffle 5 that is driven by a reciprocating cylinder and blocks the feeding channel 3;

[0099] The feeding channel 3 is designed with an inclination to facilitate unloading. The diameter of the aluminum rod placed in the feeding channel 3 should not exceed the diameter of the inlet 16, so as to meet the feeding and heating of aluminum rods of different diameters.

[0100] The aluminum rod enters through the feed channel 3 and then enters the corresponding heating chamber through the inlet 16;

[0101] Each feeding hopper is equipped with an independent baffle 5, which enables individual control of the feeding channel 3, ensuring that aluminum bars enter the heating chamber one by one in sequence.

[0102] See Figure 2 , Figure 3 and Figure 8 As shown, the inner wall of the feeding hopper is provided with two symmetrical fixed seats 7. The upper surface of the end of the fixed seat 7 is provided with a limiting groove 8, and an adaptive support unit that slides along the limiting groove 8 is slidably connected to one side of the fixed seat 7.

[0103] The adaptive support unit includes a guide seat 10, a support seat 6 is provided below the guide seat 10, and a buffer rod 11 extending into the support seat 6 is provided at the bottom of the guide seat 10.

[0104] A synchronous cylinder 15 is installed on the inner wall of the fixed seat 7 to push the support 6 to slide, and a guide rod 14 is installed on the surface of the support 6 to limit the sliding within the fixed seat 7.

[0105] A push rod that slides toward inlet 16 is embedded in the inner wall of the feeding bin on the same side. The push rod is used to push aluminum bars in the feeding bin on the same side.

[0106] The bottom surface of the guide seat 10 is provided with a pushing part 13, and the top side of the guide seat 10 is provided with a sliding plate 9 that is limited and slidable within the limiting groove 8.

[0107] The fixed seat 7 has a ramp 12 on the side facing the support 6 with the same inclination angle as the push part 13, and the surface of the ramp 12 has a notch for guiding the seat 10 to enter.

[0108] It should be noted that the skateboard 9 is located within the limiting groove 8 and slides along the limiting groove 8, thus limiting its range of motion;

[0109] In the initial state, the position of the support 6 remains stationary. The aluminum rod rolls down through the feed channel 3 to the fixed seat 7 and is temporarily supported between the two supports 6. At this time, if the center of the aluminum rod is aligned with the center of the inlet 16, no adjustment is needed and the aluminum rod can directly enter the heating chamber.

[0110] When the center of the aluminum rod is higher than the center of the inlet 16, the position of the support 6 needs to be adjusted. The synchronous cylinder 15 drives the support 6 to slide along the direction of the fixed seat 7. The support 6 moves forward smoothly under the limit of the guide rod 14, while driving the guide seat 10 and the slide plate 9 above to move as a whole.

[0111] At this time, the pushing part 13 pushes against the inclined platform 12, and the pushing part 13 drives the slide plate 9 to slide along the limiting groove 8. At this time, the guide seat 10 rises and drives the buffer rod 11 to slide at the top of the support 6. During the pushing of the pushing part 13 against the inclined platform 12, the guide seat 10 enters the notch on the surface of the inclined platform 12, realizing a stable limiting engagement with the inclined platform 12. At this time, the aluminum rod supported by the two supports 6 descends as a whole, so that the central axis of the aluminum rod is re-aligned with the center of the entrance 16, completing the adaptive centering and support adjustment, and adaptively adjusting the support height to ensure that it is aligned with the center of the entrance 16 without the need for repeated manual handling.

[0112] After centering, the push rod pushes the aluminum bar on the same side toward the center of the corresponding inlet 16, automatically feeding the material.

[0113] In use, this invention employs a clamping and rotating assembly and a supporting and transferring unit. The supporting and transferring unit is located between clamp seat 1 (26) and clamp seat 2 (18). A drive roller 20 provides support and guidance to the bottom of the aluminum rod, which is fed along the direction of the heating chamber and finally reaches the slot in clamp seat 1 (26). Multiple pressure rollers 1 (31) fix one end of the aluminum rod, and multiple pressure rollers 2 (36) in clamp seat 2 (18) fix the other end of the aluminum rod. After the roller seat 19 descends once, the aluminum rod rotates, making its heating more uniform, and the aluminum rod remains at the center of rotation. Then, the fixation on both ends of the aluminum rod is released, allowing the aluminum rod to move down to contact the drive roller 20 after the first descent. At the same time, clamp seat 1 (26) and clamp seat 2 (18) slide along the movement groove 24 under the drive of the corresponding transmission screw 2 (33), realizing that clamp seat 1 (26) and clamp seat 2 (18) move away from each other and completely separate from the two ends of the aluminum rod. The roller seat 19 descends a second time, aligning the center of the aluminum rod with the center of the outlet 27, facilitating the discharge of the aluminum rod.

[0114] By setting an adaptive support unit, when the center of the aluminum rod deviates from the center of the inlet 16, the synchronous cylinder 15 drives the support 6 to slide along the direction of the fixed seat 7. The support 6 moves smoothly forward under the limit of the guide rod 14, while driving the guide seat 10 and the slide plate 9 above to move as a whole. At this time, the pushing part 13 pushes against the inclined platform 12. The pushing part 13 drives the slide plate 9 to slide along the limiting groove 8. At this time, the guide seat 10 rises and drives the buffer rod 11 to slide at the top of the support 6. At the same time, the guide seat 10 enters the notch on the surface of the inclined platform 12 to achieve stable limiting engagement with the inclined platform 12. At this time, the aluminum rod supported by the two supports 6 descends as a whole, so that the central axis of the aluminum rod is re-aligned with the center of the inlet 16, completing the adaptive centering support adjustment and adaptively adjusting the support height to ensure that it is aligned with the center of the inlet 16.
