Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forming technology, and more particularly to an aluminum profile forming apparatus. Background Technology

[0002] Due to its excellent ductility and shaping ability, aluminum alloys are typically processed into long, strip-shaped aluminum profiles using extrusion molding. Currently, the extrusion process involves heating the aluminum rod to a specific temperature before extrusion. However, when using a gas-fired furnace to heat the aluminum rod, the rod is stationary, and the heating nozzles are in a relatively fixed position. This leads to uneven heating, directly impacting the extrusion results. Furthermore, the current method of conveying the aluminum rods typically uses large machinery such as overhead cranes. This method is inconvenient for precise feeding during heating, and the relatively small size of the gas-fired furnace also increases the risk of accidents. Additionally, this feeding method is relatively inefficient, thus necessitating improvement. Currently, during extrusion molding, the temperature of the mold is only a portion of the heat transferred from the aluminum rod or generated by friction. This results in increased friction between the aluminum fluid and the mold cavity, especially in the later stages of extrusion molding, due to the relatively low mold temperature. Ultimately, this affects the quality of the aluminum profile, mainly manifested in poor welding and remelting effects and the easy formation of weld seams at the weld joint. Summary of the Invention

[0003] This invention provides an aluminum profile forming device to overcome the shortcomings of the prior art, improve the quality of aluminum profiles and other aluminum profiles during forming, facilitate the conveying of aluminum rods, and uniformly heat the aluminum rods, thus having strong practicality.

[0004] In order to achieve the objectives of this invention, the following technologies are proposed:

[0005] An aluminum profile forming apparatus includes a feeding mechanism, a conveying mechanism at the discharge end of the feeding mechanism, a heating device at the discharge end of the conveying mechanism, and a transfer mechanism between the conveying mechanism and the heating device. The feeding mechanism feeds aluminum rods into the conveying mechanism, which in turn conveys the aluminum rods. The heating device heats the aluminum rods. The transfer mechanism conveys the heated aluminum rods to an extrusion forming apparatus for forming aluminum profiles. The feeding mechanism can store a certain amount of cut aluminum rods and can also feed individual aluminum rods to avoid rod accumulation. The conveying mechanism feeds the aluminum rods and facilitates pushing them to the heating device for heating, thus providing aluminum rods for heating or forming aluminum profiles. The transfer mechanism not only transfers the heated aluminum rods but also provides limiting support during the ejection process to ensure safety. Therefore, a pair of transfer mechanisms are typically used; while one transfer mechanism is transferring the aluminum rod, the other, driven by a trolley, moves to the point between the conveyor mechanism and the heating device to provide a limiting position during ejection. The heating device heats the aluminum rods evenly and ensures uniform heating by rotating the rods during heating, preventing heat loss and potential waste or accidents. It also pulls the aluminum rods, facilitating their transfer.

[0006] An aluminum profile forming apparatus includes an extrusion forming device. A die is housed within the extrusion forming shaft. Along the extrusion forming direction, the die sequentially comprises a flow-dividing welding zone, an induction heating zone, a cooling zone, and a forming zone. In the flow-dividing welding zone, the aluminum rod is diverted into a fluid through extrusion, and a fluid tube blank is formed through welding and remelting. The induction heating zone uses electromagnetic induction to generate eddy currents in the die, heating the fluid passing through it and raising the aluminum rod to 660°C. The cooling zone uses nitrogen cooling to cool the aluminum fluid to 530°C. The forming zone is used for forming the aluminum profile. By using the aforementioned electromagnetic induction to heat the die, the aluminum fluid remelts within the die as it passes through, eliminating grain growth and anisotropy caused by friction and extrusion after diversion, resulting in a seamless weld line in the produced aluminum profile after oxidation. Then, rapid cooling with nitrogen is used to ensure that the aluminum molten material quickly recrystallizes in the cooling zone after remelting, thus avoiding excessive grain growth in the aluminum alloy due to prolonged cooling time, and solving the problem of coarse grains caused by compression tails in forward extrusion. Furthermore, according to known technology, aluminum alloy grains tend to grow easily in the range of 480℃ to 520℃, while this solution controls the temperature drop point at 530℃, which significantly inhibits grain growth and improves the performance of the aluminum alloy. During remelting heating, considering that the aluminum molten material is prone to oxidation as the temperature increases, especially above 700℃, leading to increased doping in some aluminum profiles, heating is performed at 660℃.

[0007] Furthermore, the feeding mechanism includes an inclined plate with an arc-shaped shell at its inner end. A rear plate extends downward from the arc-shaped shell and prevents the aluminum rod transferred to the front from rolling backward, thus ensuring safety. Multiple notches are provided on the rear plate. An end plate is vertically positioned at the outer end of the inclined plate. Side circular plates are provided at both ends of the arc-shaped shell, and an arc-shaped guard plate is provided between the side circular plates. The arc-shaped guard plate is concentrically positioned with the arc-shaped shell. Limiting side plates are provided on both sides of the inclined plate. A feeding motor is mounted on one of the side circular plates. The output shaft of the feeding motor is connected to a rotating column, which has a U-shaped groove. The length direction of the inclined plate intersects with the center of the rotating column. The U-shaped groove provides a cavity for the aluminum rod to be unloaded, while the arc-shaped guard plate and arc-shaped shell prevent the aluminum rod from falling during unloading.

[0008] Furthermore, the upper end of the limiting side plate is equipped with an upper baffle. There is a feed inlet between the outer end of the upper baffle and the end plate, allowing only one aluminum rod to pass through at a time. The upper baffle prevents the aluminum rod placed on the inclined plate from falling due to compression or other reasons, thus ensuring safety. In addition, the feed inlet facilitates the insertion of the aluminum rod.

[0009] Furthermore, the conveying mechanism includes a base plate on which a pair of supporting outer plates are mounted. Side bottom plates are mounted on the upper ends of the supporting outer plates, and side guard plates are vertically bent onto the outer sides of the side bottom plates. These side guard plates limit the movement of the aluminum rod at both ends. One end of one side guard plate has a discharge hole, and the other end of the other side guard plate has a pushing hydraulic cylinder positioned directly opposite the discharge hole. The pushing hydraulic cylinder pushes the aluminum rod out of the discharge hole.

[0010] Multiple support rods are mounted on the substrate. A concave pad is mounted on the upper end of each support rod, and a middle plate is mounted on the concave pad. There is a gap between the middle plate and the side bottom plate. Both the middle plate and the side bottom plate provide support for the aluminum rod.

[0011] Furthermore, multiple rotating pins are installed in an equally spaced array along the length of the inner wall of the side guard plate. A positioning plate is rotatably mounted on each rotating pin. A rotating head is located at the upper end of the positioning plate, and a stop pin is located on one side of the rotating head, in front of the rotating head, and is mounted on the side guard plate. A spring plate with a V-shaped structure is located on the other side of the rotating head and is mounted on the side guard plate via a mounting plate. The lower end of the positioning plate has a wedge-shaped structure, and the front wall of the positioning plate is inclined, while the rear wall is flat. By rotating the positioning plate, when the moving part of the conveying mechanism moves backward, it prevents the moving part from pushing the aluminum rod backward, and the stop pin also hinders the backward rotation of the positioning plate. When the moving part of the conveying mechanism moves forward, it allows the positioning plate to rotate forward, and the spring plate allows the positioning plate to return to its original state.

[0012] Furthermore, a pair of inner plates are mounted on the substrate. A guide rail is mounted on the upper end of the inner plate. A sliding sleeve is fitted on the upper end of the guide rail. A vertical plate is mounted on the sliding sleeve. Both ends of the vertical plate are provided with protrusions. The upper ends of the protrusions are provided with second stop pins. A pair of third stop pins are also provided on the vertical plate. The third stop pins are located below the front end of the second stop pins. L-shaped arms are rotatably mounted on both ends of the vertical plate. The front end of the L-shaped arms is hinged with a lower protrusion plate. A conveying crossbar is mounted on the upper end of the lower protrusion plate on the same side. Conveying push plates are arranged in an equally spaced array along the length of the conveying crossbar. The rear side of the conveying push plate is provided with an inclined wall. The front wall of the conveying push plate is flat. The conveying crossbar moves within the interval. The rear end of the L-shaped arm is hinged with a hinge protrusion. The lower end of the hinge protrusion is provided with a movable side plate. The inner wall of the movable side plate is provided with a slide rail. A sliding sleeve is fitted inside the slide rail. The sliding sleeve is mounted on the vertical section of the concave pad. The aforementioned conveyor pusher's trajectory is a right-angled trapezoid shape. When moving forward, the conveyor pusher first moves upward. Then, when it acts on the aluminum rod, it moves forward again. After pushing the aluminum rod a certain distance, the conveyor pusher first moves vertically downward, then backward, and pushes the aluminum rod again. This method allows for continuous feeding of aluminum rods, thus improving efficiency. Furthermore, this method takes into account the rolling nature of the aluminum rod, therefore requiring relatively less pushing force.

[0013] When the conveyor pusher acts on the aluminum rod for conveying the rod, the lower rear wall of the L-shaped arm acts on the second stop pin, and the front section of the L-shaped arm extends upward at an angle. When the conveyor pusher moves backward, the lower front wall of the L-shaped arm acts on the third stop pin, and the rear section of the L-shaped arm extends upward at an angle. Therefore, the setting of the second and third stop pins facilitates the movement of the conveyor pusher, and when the conveyor pusher moves backward, it also prevents the L-shaped arm from rotating excessively.

[0014] Furthermore, a first swing plate is hinged to the vertical plate, and a second swing plate is hinged to the lower end of the first swing plate. The second swing plate has an oblong hole, and its lower end is hinged to the inner plate. An actuating rod passes through the oblong hole, and a rotating disk is mounted on the actuating rod. The actuating rod is eccentrically positioned on the rotating disk, which has a rotating shaft. Both ends of the rotating shaft are located on the inner plate, and driven wheels are mounted on the rotating shaft. Driven wheels are connected to drive wheels via belts, and rotating seats are located at both ends of the drive wheels. The rotating seats are mounted on the base plate, and a conveyor motor is mounted on the rotating seats. The output shaft of the conveyor motor is located on the drive wheel. Through the first swing plate, the second swing plate, and the actuating rod, the vertical plate can reciprocate by the swinging of the second swing plate, thus facilitating the feeding motion of the aluminum rod by the conveyor pusher.

[0015] Furthermore, the transfer mechanism includes a traveling crane with multiple mounting columns. Each mounting column has four mounting rods arranged in a circular array. Each mounting rod has a connecting plate, and rollers are positioned between adjacent connecting plates. The rollers are tangent to the outer wall of the aluminum rod. A concave seat is mounted at one end of each mounting rod, and a transfer motor is mounted at the outer end of the concave seat. The output shaft of the transfer motor is connected to a conveyor wheel, which is also tangent to the outer wall of the aluminum rod. The rollers support the aluminum rod and facilitate its ejection. Additionally, the conveyor wheel drives the aluminum rod, facilitating feeding and discharging operations.

[0016] Furthermore, the heating device includes a mounting frame, on which a gas heater is mounted. A pair of first L-shaped plates are mounted at one end of the gas heater, and a pair of opening and closing plates are positioned between the first L-shaped plates. The opening and closing plates are internally made of refractory material, and opening and closing cylinders are located on the outer ends of the opening and closing plates. These cylinders are respectively mounted on the gas heater. The opening and closing plates allow for the sealing of one end of the furnace, thereby preventing safety accidents during heating.

[0017] At the other end of the gas heater, a pair of second L-shaped plates are installed. An end cover plate is movably installed between the second L-shaped plates. The upper end of the end cover plate is connected to a lower insertion hydraulic cylinder. The lower end of the lower insertion hydraulic cylinder is installed on the gas heater via an mounting arm. The end cover plate has an end cap, and a fixing frame is installed on the end cap. An inward pushing hydraulic cylinder is installed on the outer end of the fixing frame. A movable frame is installed on the movable end of the inward pushing hydraulic cylinder. A rotating motor is installed on the movable frame. Multiple guide rods pass through the rotating motor and are located on the end cover. The output shaft of the rotating motor is connected to a rotating disk. The rotating disk has multiple spikes and is made of refractory material. The end cover plate can seal the other end of the furnace. When the rotating disk is pressed against one end of the aluminum rod by the action of the inward pushing hydraulic cylinder, it can drive the aluminum rod to rotate under the drive of the rotating motor. The spikes can increase the friction during rotation. In addition, in order to move the aluminum rod into the furnace body, an aluminum rod support frame made of refractory material can be installed inside the other end of the gas heater. This support frame can effectively support the other end of the aluminum rod before it is rotated.

[0018] Furthermore, a bent arm is installed at one end of the gas heater, a guide sleeve is installed on the bent arm, a movable part passes through the guide sleeve, a rack is installed on one side of the movable part, a pair of drive seats are installed on the guide sleeve, a drive gear is provided between the drive seats, a drive motor is connected to the drive gear, and the drive motor is installed on the drive seats.

[0019] The inner end of the moving part is rotatably equipped with a heat-insulating protective shell. A water pipe, filled with circulating cooling water, is located inside the heat-insulating protective shell. An end plate is mounted on the outer end of the heat-insulating protective shell, and an end crossbar is mounted on the end plate. Both ends of the end crossbar have rounded end plates, and a connecting arm is hinged to the other end of each rounded end plate. The other end of the connecting arm has a gripper with a wedge-shaped clamping end. A deflection plate is vertically mounted on the inner end of the connecting arm, and an elongated working hole is opened on the inner end of the deflection plate. A through pin passes through the working hole, and a pull plate is mounted on the through pin. A rear pull plate is installed on the rear side of the pull plate, passing through the end crossbar. A pair of cross plates are hinged to the other end of the rear pull plate, forming a cross-shaped structure. Each cross plate has a tension protrusion hinged to its other end. Clamping end plates are installed at both ends of the end crossbar, and a clamping screw is rotatably mounted between the clamping end plates. The threads at both ends of the clamping screw rotate in opposite directions, and a moving seat is screwed to each end of the clamping screw. The moving seat is located on the tension protrusion. Holes are provided on the heat insulation protective shell, allowing the clamping screw to rotate through these holes. With the above-described clamping components, the aluminum rod is easily pulled into the furnace during heating. It also features high clamping stability.

[0020] The advantages of the above technical solution are:

[0021] This invention facilitates the feeding and conveying of aluminum rods. Compared with existing technologies, the feeding and conveying methods provided by this invention offer high precision and efficiency, essentially solving the problem of difficult aluminum rod feeding. Secondly, it facilitates uniform heating of the aluminum rods. Compared with existing technologies, the solution provided by this invention improves heating uniformity by rotating the aluminum rods during heating. Furthermore, this invention facilitates the transfer of heated aluminum rods. Moreover, during aluminum profile processing, by appropriately heating and cooling the mold at suitable locations, it ensures both the quality and strength of the aluminum profiles, thus possessing epoch-making significance.

[0040] Figure 18 The three-dimensional structure of the heating device is shown. Figure 5 . Detailed Implementation

[0041] like Figure 1As shown, an aluminum profile forming apparatus includes a feeding mechanism 1, a conveying mechanism 2 at the discharge end of the feeding mechanism 1, a heating device 4 at the discharge end of the conveying mechanism 2, and a transfer mechanism 3 between the conveying mechanism 2 and the heating device 4. The feeding mechanism 1 is used to feed aluminum rods to the conveying mechanism 2, the conveying mechanism 2 is used to convey aluminum rods, the heating device 4 is used to heat the aluminum rods, and the transfer mechanism 3 is used to convey the heated aluminum rods to the extrusion forming apparatus for forming aluminum profiles through the extrusion forming apparatus.

[0042] like Figure 2 As shown, an aluminum profile forming apparatus further includes an extrusion forming device. A die is disposed within the extrusion forming shaft. Along the extrusion forming direction, the die is sequentially configured with a flow-diverting welding zone 5, an induction heating zone 6, a cooling zone 7, and a forming zone 8. The flow-diverting welding zone 5 uses extrusion to divert the aluminum rod into a fluid, forming a fluid tube blank through welding and remelting. The induction heating zone 6 uses electromagnetic induction to generate eddy currents in the die, heating the fluid passing through it and raising the aluminum rod to 660°C. The cooling zone 7 uses nitrogen cooling to cool the aluminum fluid to 530°C. The forming zone 8 is used for forming the aluminum profile.

[0043] In general, in this embodiment, the cut aluminum rods are first transferred to the feeding mechanism for storage. When aluminum rods need to be fed, the feeding mechanism transfers them one by one to the conveying mechanism 2, and the conveying mechanism 2 transports the aluminum rods one by one. Finally, the aluminum rods are pushed to one of the transfer mechanisms 3, and supported by the transfer mechanism 3, they are pushed to the heating device 4 for heating under rotation. After heating, the heating device 4 pushes the aluminum rods to another transfer mechanism 3, and the transfer mechanism 3 transfers the aluminum rods to the extrusion forming device for forming aluminum profiles. During forming, the aluminum rods are divided into multiple streams by the strong extrusion through the diversion welding zone. When the aluminum fluid passes through the induction heating zone 6, the mold and the fluid inside are heated, thereby improving the remelting and welding effect of the aluminum fluid during the remelting process and avoiding weld seams. When the aluminum fluid passes through the cooling zone 7, it can quickly reduce the temperature of the mold and the aluminum fluid, thereby preventing the growth of aluminum grains and ultimately forming an aluminum profile in the forming zone 8.

[0044] like Figure 3As shown, the feeding mechanism 1 includes an inclined plate 100, an arc-shaped shell 101 at the inner end of the inclined plate 100, a rear plate 102 extending downward from the arc-shaped shell 101, a plurality of notches 103 on the rear plate 102, an end plate 104 perpendicularly provided at the outer end of the inclined plate 100, side circular plates 105 respectively provided at both ends of the arc-shaped shell 101, an arc-shaped guard plate 109 provided between the side circular plates 105, the arc-shaped guard plate 109 being concentrically arranged with the arc-shaped shell 101, a limiting side plate 106 provided on the side circular plate 105, the limiting side plate 106 being provided on both sides of the inclined plate 100, a feeding motor 108 mounted on one of the side circular plates 105, the output shaft of the feeding motor 108 being connected to a rotating column 110, a U-shaped groove 111 provided on the rotating column 110, the length direction of the inclined plate 100 intersecting with the center of the rotating column 110. The upper end of the limiting side plate 106 is provided with an upper baffle 107. There is a feed port between the outer end of the upper baffle 107 and the end plate 104. Only one aluminum rod is allowed to pass through the feed port.

[0045] In this embodiment, when feeding aluminum rods, the operator loads the cut aluminum rods onto the inclined plate 100 through the feed inlet. During conveying, the rotating column 110 rotates under the drive of the feeding motor 108, and the U-shaped groove 111 is aligned with the aluminum rod at the front end. Then, the aluminum rod rolls into the U-shaped groove 111 under its own weight. After that, the rotating column 110 rotates downward, causing the aluminum rod to fall from the lower opening of the arc-shaped guard plate 109 and the arc-shaped shell 101 onto one end of the middle plate 208, and then waits for the transfer operation of the aluminum rod.

[0046] like Figures 4 to 5 As shown, the conveying mechanism 2 includes a base plate 200. A pair of supporting outer plates 201 are mounted on the base plate 200. Side bottom plates 202 are respectively mounted on the upper end of the supporting outer plates 201. Side guard plates 203 are vertically bent on the outer side of the side bottom plates 202. One end of one side guard plate 203 is equipped with a discharge hole 204, and one end of the other side guard plate 203 is equipped with a push hydraulic cylinder 205, which is directly opposite the discharge hole 204. Multiple support rods 206 are mounted on the base plate 200. A concave pad 207 is mounted on the upper end of the support rod 206. A middle plate 208 is mounted on the concave pad 207, and there is a gap between the middle plate 208 and the side bottom plates 202.

[0047] like Figure 6As shown, multiple rotating pins 209 are installed in an equally spaced array along the length of the inner wall of the side guard plate 203. A positioning plate 210 is rotatably mounted on the rotating pins 209. A rotating head 211 is provided at the upper end of the positioning plate 210. A stop pin 212 is provided on one side of the rotating head 211. The stop pin 212 is located in front of the rotating head 211 and is located on the side guard plate 203. A spring plate 213 is provided on the other side of the rotating head 211. The spring plate 213 has a V-shaped structure and is mounted on the side guard plate 203 through a mounting plate 214. The lower end of the positioning plate 210 has a wedge-shaped structure, and the front wall of the positioning plate 210 is inclined, while the rear wall of the positioning plate 210 is flat.

[0048] like Figures 7 to 9 As shown, a pair of inner plates 215 are mounted on the substrate 200. A guide rail 216 is mounted on the upper end of the inner plate 215. A sliding sleeve 217 is fitted on the upper end of the guide rail 216. A vertical plate 218 is mounted on the sliding sleeve 217. A protrusion 228 is provided at both ends of the vertical plate 218. A second stop pin 229 is provided at the upper end of the protrusion 228. A pair of third stop pins 219 are also provided on the vertical plate 218. The third stop pins 219 are located below the front end of the second stop pins 229. L-shaped arms 220 are rotatably provided at both ends of the vertical plate 218. A lower protrusion 221 is hinged to the front end of the L-shaped arm 220 and located on the same side. The lower convex plate 221 is equipped with conveying crossbars 222. Conveying push plates 223 are arranged in an evenly spaced array along the length of the conveying crossbars 222. The rear side of each conveying push plate 223 has an inclined wall, while the front wall is flat. The conveying crossbars 222 move within the intervals. The rear end of the L-shaped arm 220 is hinged to a hinge protrusion 224. A movable side plate 225 is located at the lower end of the hinge protrusion 224. A slide rail 226 is provided on the inner wall of the movable side plate 225. A sliding sleeve 227 is fitted inside the slide rail 226 and is mounted on the vertical section of the concave pad 207. When the conveying push plate 223 acts on the aluminum rod and is used for conveying the aluminum rod, the lower rear wall of the L-shaped arm 220 acts on the second stop pin 229, and the front section of the L-shaped arm 220 extends upwards at an angle. When the conveyor push plate 223 moves backward, the lower wall of the front section of the L-shaped arm 220 acts on the third stop pin 219, and the rear section of the L-shaped arm 220 extends upward at an angle.

[0049] A first swing plate 230 is hinged to the vertical plate 218. A second swing plate 231 is hinged to the lower end of the first swing plate 230. The second swing plate 231 has an oblong hole 232. The lower end of the second swing plate 231 is hinged to the inner plate 215. An actuating rod 234 passes through the oblong hole 232. A rotating disk 235 is provided on the actuating rod 234. The actuating rod 234 is eccentrically positioned on the rotating disk 235. A rotating shaft is provided on the rotating disk 235. Both ends of the rotating shaft are located on the inner plate 215. A driven wheel 236 is provided on the rotating shaft. The driven wheel 236 is connected to a driving wheel 238 via a belt 237. Rotating seats 239 are provided at both ends of the driving wheel 238. The rotating seats 239 are mounted on the base plate 200. A conveyor motor 240 is mounted on the rotating seat 239. The output shaft of the conveyor motor 240 is located on the driving wheel 238.

[0050] In this embodiment, during implementation, the material is transferred to one end of the middle plate 208 via the feeding mechanism 1. During conveying, the conveying motor 240 is started, and the drive wheel 238 rotates under the drive of the conveying motor 240. The rotation of the drive wheel 238 drives the driven wheel 236 to rotate via the belt 237. When the driven wheel 236 rotates, it drives the rotating shaft to rotate. The rotation of the rotating shaft drives the rotating disk 235 to rotate. When the rotating disk 235 rotates, it drives the actuating rod 234 to rotate around the axis of the rotating disk 235. As the actuating rod 234 rotates, it acts on the waist-shaped hole 232, thereby causing the second swing plate 231 to swing forward around its lower end. The forward swing of the second swing plate 231 drives the vertical plate 218 to move forward. When the vertical plate 218 moves forward, it drives the L-shaped arm 220 to move forward. The segment moves upward and forward until the lower wall of the rear segment of the L-shaped arm 220 acts on the second stop pin 229. Then, driven by the vertical plate 218, the conveying push plate 223 pushes the aluminum rod located on the middle plate 208 forward to the next empty position. During the movement, the positioning plate 210 rotates forward. This movement will cause the aluminum rod located at the front end to move to the discharge hole 204. Then, the conveying push plate 223 will move backward under the drive of the vertical plate 218, etc. At this time, the positioning plate 210 will not rotate backward due to the limit of the stop pin 212. At this time, the conveying push plate 223 will move downward and then move backward under the middle plate 208. When it moves to the initial position, it will push the aluminum rod again. During the backward movement of the conveying pusher plate 223, the top-pushing hydraulic cylinder 205 pushes the aluminum rod located at the front end out of the discharge hole 204 and pushes it through the transfer mechanism 3 to the heating device 4 for heating. After the heating is completed, it is transferred out and another aluminum rod is conveyed and pushed out again.

[0051] like Figure 10 and Figure 11As shown, the transfer mechanism 3 includes a trolley with multiple mounting columns 30 mounted on it. Each mounting column 30 has four mounting rods 31 mounted on it in a circular array. Each mounting rod 31 has a connecting plate 32 mounted on it. Rollers 33 are provided between adjacent connecting plates 32. The rollers 33 are tangent to the outer wall of the aluminum rod. A concave seat 34 is mounted on one end of the mounting rod 31. A transfer motor 35 is mounted on the outer end of the concave seat 34. The output shaft of the transfer motor 35 is connected to a conveying wheel 36, which is tangent to the outer wall of the aluminum rod.

[0052] In this embodiment, when implemented, there are two transfer mechanisms 3, both of which are installed on the crane, thereby improving the efficiency of aluminum rod turnover.

[0053] In this embodiment, the aluminum rod is supported by roller 33 when it is pushed out, and when the aluminum rod comes into contact with the conveyor wheel 36, the aluminum rod can be driven forward by the active drive of the conveyor wheel 36.

[0054] like Figure 12 and Figure 18 As shown, the heating device 4 includes a mounting bracket 400, on which a gas heater 401 is mounted. A pair of first L-shaped plates 402 are mounted on one end of the gas heater 401. A pair of opening and closing plates 403 are provided between the first L-shaped plates 402. The opening and closing plates 403 are made of refractory material. An opening and closing cylinder 404 is provided on the outer end of the opening and closing plate 403.

Then, the opening and closing cylinder 404 causes the opening and closing plate 403 to seal one end of the gas heater 401. Then, the end cover plate 432 and other components move downwards via the lowering hydraulic cylinder 431. After completely sealing the other end of the gas heater 401, the rotating disk is pushed inwards by the inner thrust hydraulic cylinder 435, eventually bringing the rotating disk into contact with the aluminum rod. Subsequently, the aluminum rod is positioned in the heating zone of the gas heater 401 by the pulling of the drive motor 408 and the pushing of the inner thrust hydraulic cylinder 435. Then, the rotating motor 437 is started to make the aluminum rod rotate and heat it during rotation until heating is complete.
