Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing technology, specifically a furnace feeding device for heat treatment of aluminum billet. Background Technology

[0002] Aluminum is an excellent conductive material, and my country has abundant aluminum resources. However, aluminum oxidizes very easily in air, affecting the conductivity of the bonding surface. Copper-aluminum composite materials use copper for the outer layer and aluminum for the inner core. This maintains the strong oxidation resistance and good contact performance of copper while taking full advantage of aluminum's light weight and low price.

[0003] Common aluminum profiles are mainly produced by melting and casting to form cylindrical aluminum ingots with different material formulas. Then, the oxide layer on the surface is removed by a car body. The aluminum billet is then transferred to the downstream for specific product processing. First, the aluminum billet is heated in a heating furnace, then slit, and after slit, it is extruded and shaped by a mold. The shaped aluminum material is then straightened, and then surface treatments such as spraying are performed to improve the aesthetics and corrosion resistance of the profile.

[0004] The existing aluminum profile production process involves cutting long aluminum bars into sections, heating them in a furnace, and then extruding them in an extruder. While this ensures that the aluminum bars are heated section by section, it requires cutting the aluminum bars into sections, which is time-consuming and labor-intensive. Furthermore, the short sections of aluminum bars after cutting also need to be fed into the furnace for heating in sequence, making the process cumbersome and lacking in automation. Utility Model Content

[0005] To address the problems of time-consuming and labor-intensive aluminum rod cutting, cumbersome procedures, and low automation in existing aluminum rod heat treatment feeding devices, this utility model provides an aluminum rod billet heat treatment furnace feeding device.

[0006] This utility model is achieved through the following technical solution: A furnace feeding device for heat treatment of aluminum billet includes a feeding rack capable of placing aluminum billets and guiding them to roll downwards, with a billet separation mechanism connected and installed on one side of the feeding rack. The bar stock separation mechanism includes a second rotating shaft rotatably connected to one side of the feeding rack, with levers connected to both sides of the second rotating shaft, and a telescopic cylinder rotatably connected to the lower side of the feeding rack. The extended end of the telescopic cylinder is rotatably connected to the side of the lever away from the second rotating shaft. A conveying mechanism is provided on the side of the material rack near the bar stock separation mechanism; The conveying mechanism includes a fixed frame with an installation channel in the middle, two opposing sliding grooves connected and installed on the upper side of the fixed frame, corresponding mounting plates connected and installed above the sliding grooves, several conical blocks rotatably connected and installed on the inner side of the mounting plates, sliders slidably connected and installed in the two sliding grooves respectively, a push plate connected and installed between the two sliders, and a feeding mechanism that enables the push plate to reciprocate along the fixed frame.

[0007] A further improvement of this utility model is that the feeding mechanism includes a first rotating shaft rotatably connected and installed at both ends of the fixed frame, and a sprocket is connected and installed in the middle of the two first rotating shafts. A motor that drives the first rotating shaft to rotate is provided on one side of the fixed frame. The two sprockets are connected by chain drive, and the beginning and end of the chain are connected and installed to the lower side of the push plate.

[0008] A further improvement of this utility model is that the material rack is provided with two opposing guide rails on the side away from the motor. Each guide rail is slidably connected to a slide plate that is rotatably connected to the sprocket. A bolt passing through the steel pipe of the material rack is provided on one side of the slide plate, and nuts that are screwed onto the bolt and pressed against both sides of the steel pipe of the material rack are screwed on the bolt.

[0009] A further improvement of this utility model is that a first pulley is connected and installed at the output end of the motor, and a second pulley is connected and installed on the outer side of the first rotating shaft, with the first pulley and the second pulley connected by belt drive.

[0010] A further improvement of this utility model is that a baffle is provided on the material rack.

[0011] A further improvement of this utility model is that limit switches are provided on both sides of the fixing frame.

[0012] A further improvement of this invention is that the slider is a rotatable roller.

[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In operation, bundles of aluminum billets are hoisted onto a storage rack by an overhead crane, arranging the billets in a row. A telescopic cylinder on the billet separation mechanism rotates a lever, transferring a single billet from the storage rack to the conveyor mechanism. The billet then falls between conical blocks, and the feed mechanism on the conveyor mechanism drives a pusher plate to slide along a slide rail, propelling the billet into the heating furnace. This device, through the storage rack and the billet separation mechanism, transports aluminum billets one by one to the conveyor mechanism, which then conveys them into the heating furnace for heating. This automated transport of aluminum billets avoids the time-consuming and labor-intensive process of cutting billets into segments, reducing the workload of personnel. Attached Figure Description

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figure 1-5 As shown, an aluminum billet heat treatment furnace feeding device includes a material rack 1 that can place aluminum billets and guide them to roll downwards. A billet separation mechanism 2 is connected and installed on one side of the material rack 1, which can push the aluminum billets one by one. The top of the material rack 1 is a beam that is inclined towards the billet separation mechanism 2, so that the aluminum billets can roll downwards under the action of gravity. The bar stock separation mechanism 2 includes a second rotating shaft 21 rotatably connected and installed on one side of the material rack 1. A lever 22 is connected and installed on both sides of the second rotating shaft 21. A telescopic cylinder 23 is rotatably connected and installed on the lower side of the material rack 1. The extended end of the telescopic cylinder 23 is rotatably connected and installed on the side of the lever 22 away from the second rotating shaft 21.

[0023] A conveying mechanism 3 is provided on the side of the material rack 1 near the bar stock separation mechanism 2; The conveying mechanism 3 includes a fixed frame 31 with an installation channel in the middle. Two opposing sliding grooves 36 are connected and installed on the upper side of the fixed frame 31. Corresponding mounting plates 39 are connected and installed above the sliding grooves 36. Several conical blocks 310 are rotatably connected and installed inside the mounting plates 39. The conical blocks 310 can support the aluminum rod and constrain the aluminum rod to be in the center position, so that it is aligned with the entrance of the heating furnace. Sliding blocks 38 are slidably connected and installed in the two sliding grooves 36 respectively. A push plate 37 is connected and installed between the two sliding blocks 38. The mechanism also includes a feeding mechanism 30 that enables the push plate 37 to reciprocate horizontally along the fixed frame 31.

[0024] In use, the aluminum bars on the material rack 1 are arranged in a row under the action of gravity. The aluminum bars close to the dial block 22 will be just stuck on the dial block 22. The telescopic cylinder 23 is activated to extend and retract, so that the two dial blocks 22 rotate together and move the corresponding aluminum bars to the other side. Under the action of inertia, the aluminum bars slowly roll into the conveying mechanism 3. The telescopic cylinder 23 is a hydraulic telescopic cylinder with sufficient force to push the aluminum bars one by one. The dial block 22 is reset under the action of the telescopic cylinder 23, so that the next aluminum bar is in the position to be moved. The above operation is repeated to continuously transfer the bars one by one to the conveying mechanism 3, so that the aluminum bars fall between the conical blocks 310. The feeding mechanism 30 drives the push plate 37 to slide along the slide groove 36 through the slider 38. This device uses a storage rack 1 for storing aluminum bars and a bar separation mechanism 2 to transport aluminum bars one by one to a conveying mechanism 3. The conveying mechanism 3 then transports the aluminum bars into a heating furnace for heating, thus realizing automated handling and conveying of aluminum bars. This avoids the time-consuming and labor-intensive process of cutting aluminum bars into segments and reduces the labor intensity of personnel.

[0025] It should be noted that both the material rack 1 and the fixing frame 31 need to be fixed to the ground with anchor bolts to prevent the device from tipping over and causing danger when the heavy aluminum rods roll.

[0026] The feeding mechanism 30 includes a first rotating shaft 32 rotatably connected to both ends of a fixed frame 31. A sprocket 33 is connected and installed between the two first rotating shafts 32. A motor 34, which drives the first rotating shafts 32, is located on one side of the fixed frame 31. The motor 34 is a motor with a reducer, capable of outputting high torque and low speed, and includes internal brake pads. The two sprockets 33 are connected by a chain 35, the ends of which are connected to the lower side of the push plate 37. In use, the motor 34 is started, driving the sprockets 33 to rotate via the first rotating shafts 32. The sprockets 33 then drive the chain 35 to rotate, causing the chain 35 to pull the push plate 37 along the slide groove 36 via the slider 38, thus pushing the aluminum rod into the heating furnace. After the aluminum rod is completely pushed into the furnace, the motor 34 needs to reverse to return the push plate 37 to its original position.

[0027] It should be noted that the feeding mechanism 30 can also be a hydraulic telescopic rod, a gear and rack linear reciprocating motion mechanism, or a belt reciprocating transmission mechanism, as long as it can drive the push plate to reciprocate.

[0028] The material rack 1 has two opposing guide rails 4 on the side away from the motor 34. Each guide rail 4 has a sliding plate 5 slidably connected to and rotatably connected to the sprocket 33. One side of the sliding plate 5 has a bolt 6 passing through the steel pipe of the material rack 1. Nuts 7, which press against both sides of the steel pipe of the material rack 1, are screwed onto the bolt 6. Tightening the nuts 7 allows the sliding plate 5 to move on the guide rails 4, adjusting the center distance between the corresponding sprockets 33. This ensures the chain 35 is tensioned, reduces wear between the chain 35 and the sprockets 33, improves service life, prevents chain slippage and tooth skipping, reduces vibration and noise, and allows for distance adjustment by tightening the bolts 6 on both sides.

[0029] The motor 34 has a first pulley 8 connected to its output end, and a second pulley 9 is connected to the outer side of the first shaft 32. The first pulley 8 and the second pulley 9 are connected by a belt 10. Both the first pulley 8 and the second pulley 9 are multi-grooved pulleys, allowing for the installation of two or more belts 10 to improve transmission capacity. The belt drive operates smoothly, requires no lubrication, and is easy to clean. In the event of excessive resistance or jamming, slippage will occur between the belt and the pulley, providing overload protection for the motor and preventing it from burning out.

[0030] The material rack 1 is equipped with a baffle 11. The baffle 11 can help ensure that the aluminum bars are aligned when placed, and prevent the aluminum bars from being placed incorrectly, so that they cannot fall into the correct position when rolling down.

[0031] Limit switches 12 are provided on both sides of the fixed frame 31. The push plate 37 moves at a constant speed under the drive of the chain 35. When it moves to both ends of the conveyor mechanism 3, it will touch the limit switch 12, which will immediately cut off the power. The brake module in the motor 34 can respond quickly and brake by friction, which will immediately stop the push plate 37 and prevent the end of the push plate 37 from jamming and causing overload.

[0032] The slider 38 is a rotatable roller. The roller can change sliding friction into rolling friction, which greatly reduces frictional resistance, requires no maintenance, does not require lubrication of the slide groove 36, reduces manufacturing costs, and can be used with a simple slide rail.

[0033] Limit switch 12, motor 34, solenoid valve controlling hydraulic telescopic cylinder 23, and controller are electrically connected. The controller can be a common PLC controller, such as Siemens S7-200+ series. It can operate continuously and automatically by setting a program, linking the heating furnace and the cutting of the extrusion end to control the feeding speed and feeding distance of the aluminum rod. Limit switch 12 determines whether the telescopic cylinder 23 can be started to move and transfer the aluminum rod. It automatically determines the number of processing times based on the length of the aluminum rod to determine the corresponding processing program.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
