Description

Technical Field

[0001] This utility model relates to the field of waste aluminum burning loss measurement technology, and in particular to a waste aluminum forming device. Background Technology

[0002] Burn-off rate (melting oxidation loss rate) is a core indicator for evaluating the recycling value of scrap aluminum and the quality of the smelting process. Traditional methods for calculating burn-off rate often require manual, small-batch feeding of scrap aluminum into the crucible of the melting machine. This process is not only time-consuming and labor-intensive but can also lead to furnace temperature fluctuations, affecting smelting efficiency and increasing the workload and safety risks for operators. Furthermore, the varying shapes and densities of scrap aluminum not only affect its heat transfer efficiency during smelting but also make the burn-off rate calculation inaccurate and difficult to obtain reliable data. Therefore, designing a device that can efficiently and quickly compress scrap aluminum into a regular shape with high density is crucial. Such a device can significantly improve the pretreatment process of scrap aluminum, increase feeding efficiency, reduce heat loss, and ensure the authenticity and accuracy of experimental data. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a waste aluminum forming device.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0005] A waste aluminum forming device, comprising:

[0006] A workbench with an opening on its surface;

[0007] Support legs, which are multiple in number, are installed at the bottom of the worktable to support it.

[0008] The telescopic device consists of two parts, which are vertically installed at both ends of the workbench surface.

[0009] The crossbeam is installed on top of the telescopic device; the telescopic device drives the crossbeam to move up and down.

[0010] The extrusion cylinder is located at the opening of the workbench. The two sides of the extrusion cylinder are connected to two telescopic devices via connecting plates. There is a gap between the bottom of the extrusion cylinder and the workbench.

[0011] The base plate is movably located between the bottom of the extrusion cylinder and the worktable, and the bottom of the extrusion cylinder is sealed by the base plate.

[0034] Example 1:

[0035] Combined with appendix Figures 1-4 A waste aluminum forming device includes a worktable 1, a telescopic device, an extrusion cylinder 5, and a base plate 6. The worktable 1 has an opening extending through its thickness in the center of its surface, allowing the waste aluminum to fall and be discharged smoothly after forming. Multiple support legs 2 are evenly distributed and installed at the bottom of the worktable 1, providing stable support for the entire device on the ground or other load-bearing surface. Figure 1As shown, each of the four corners of the bottom of the workbench 1 is provided with a support leg 2. The four support legs 2 are arranged in a rectangular pattern, which can provide stable support for the workbench 1 and effectively prevent the equipment from tilting or shaking during operation.

[0036] Telescopic devices are vertically installed at both ends of the workbench 1, symmetrically arranged on the left and right sides of the workbench 1. A crossbeam 4 is fixedly connected to the top of each telescopic device, extending horizontally and spanning between the two devices, forming part of the overall frame structure. By controlling the movement of the telescopic devices, the crossbeam 4 can be driven to move vertically up and down. An extrusion cylinder 5 is suspended above the opening area of ​​the workbench 1. This extrusion cylinder 5 is a cylindrical container used to hold the scrap aluminum to be compressed. Specifically, the outer walls of both sides of the extrusion cylinder 5 are fixedly connected to the corresponding parts of the two telescopic devices via connecting plates. Simultaneously, a certain vertical gap is maintained between the bottom of the extrusion cylinder 5 and the workbench 1, this gap accommodating a movable base plate 6.

[0037] The base plate 6 is a flat plate structure, larger than the bottom opening of the extrusion cylinder 5, thus completely sealing the bottom outlet of the extrusion cylinder 5. When the base plate 6 is in the sealed state, the operator can feed loose scrap aluminum into the extrusion cylinder 5 through the top opening, ensuring that the material does not fall out before compression. A connecting column 7 extends downward from the center of the bottom of the crossbeam 4, and the axis of the connecting column 7 coincides with the central axis of the extrusion cylinder 5. A pressure head 8 is fixedly installed at the end of the connecting column 7. The shape of the pressure head 8 is adapted to the inner cavity of the extrusion cylinder 5, and the two are coaxial to ensure that the pressure is applied evenly to the scrap aluminum.

[0038] During the feeding operation, first control the telescopic device to move the crossbeam 4 upwards, thereby raising the pressure head 8 to a position higher than the top of the extrusion cylinder 5, thus providing sufficient operating space for feeding. At this time, the operator can load the scrap aluminum material into the cylinder from the top of the extrusion cylinder 5. After feeding is completed, activate the telescopic device again to drive the crossbeam 4 downwards. The crossbeam 4, through the connecting column 7, drives the pressure head 8 to move downwards synchronously, entering the interior of the extrusion cylinder 5 and applying continuous pressure to the scrap aluminum material inside, ultimately compressing the loose scrap aluminum material into a dense cylindrical block.

[0039] After the scrap aluminum is compressed and formed, it needs to be ejected from the extrusion cylinder 5 for subsequent burn-off calculation. To do this, the bottom plate 6 is first removed from the bottom of the extrusion cylinder 5, so that it no longer blocks the discharge port of the extrusion cylinder 5, thus connecting the bottom of the extrusion cylinder 5 with the opening on the worktable 1. Then, the telescopic device is activated again, causing the pressure head 8 to continue descending, pushing the formed cylindrical scrap aluminum through the bottom of the extrusion cylinder 5 and falling through the opening on the worktable 1, completing the demolding process. This device has a simple overall structure, a clear operating procedure, and is easy to operate, making it suitable for scrap aluminum pretreatment in laboratory or small-batch production scenarios.

[0040] It should be noted that the diameter of the opening on the workbench 1 is larger than the inner diameter of the extrusion cylinder 5. This design ensures that the formed cylindrical scrap aluminum material will not get stuck when passing through the opening of the workbench 1 due to insufficient clearance.

[0041] Furthermore, in the experiment of calculating the burn-off rate of scrap aluminum, because the scrap aluminum prepared by this device is in a regular cylindrical shape with high density and uniformity, it can be completely added into the crucible of the melting machine in one go, without the need for batch addition as in traditional methods. Compared with the existing technology that requires repeatedly opening and closing the crucible lid and adding fragments one by one, this method significantly shortens the feeding time and improves the feeding efficiency. At the same time, because the feeding process is completed quickly, heat loss caused by prolonged exposure of the crucible is reduced, which helps to maintain a stable temperature inside the furnace, thereby accelerating the melting rate of the scrap aluminum. More importantly, rapid and concentrated feeding makes the combustion environment closer to the actual working conditions, reducing the measurement deviation of oxidation loss, making the final burn-off data more realistic and reliable, and improving the accuracy and repeatability of the experimental results.

[0042] Example 2:

[0043] Combined with appendix Figure 1 and 2 A waste aluminum forming device differs from Embodiment 1 in that the installation method of the base plate 6 is improved based on the structure described in Embodiment 1. Specifically, an extension is provided on one side of the base plate 6, which is rotatably connected to one of the telescopic devices, allowing the base plate 6 to rotate around the telescopic device. When waste aluminum extrusion forming is required, the operator can rotate the base plate 6 around the telescopic device to a blocking position, so that it completely covers the bottom outlet of the extrusion cylinder 5, achieving a sealing function; when compression is completed and the material is ready to be discharged, the base plate 6 is rotated in the opposite direction, so that it rotates around the telescopic device to a position offset from the bottom of the extrusion cylinder 5, thereby opening the discharge channel and making the bottom of the extrusion cylinder 5 corresponding to the opening of the worktable 1, facilitating the pressure head 8 to push the formed material downward.

[0044] Furthermore, to facilitate manual operation, a handle 9 is fixedly installed on the side of the base plate 6 away from the extension. The operator can smoothly rotate the base plate 6 by holding the handle 9, improving operational convenience and safety. This structure simplifies the disassembly and assembly process of the base plate 6 while retaining its original functions, avoiding the inconvenience caused by frequent handling, and is especially suitable for continuous operation.

[0045] Example 3:

[0046] Combined with appendix Figures 1-2A waste aluminum forming device is further improved based on Embodiment 1 or Embodiment 2. A guide cover 10 is added to the top port of the extrusion cylinder 5. The guide cover 10 has a funnel-shaped structure, wider at the top and narrower at the bottom. Its lower end is fixedly connected to the top of the extrusion cylinder 5, and its upper end expands outwards. The function of the guide cover 10 is to increase the effective area of ​​the feed inlet, guide the waste aluminum material to slide smoothly into the extrusion cylinder 5, reduce material spillage or blockage during feeding, and improve feeding efficiency and operational comfort.

[0047] Meanwhile, to further enhance the overall rigidity and load-bearing capacity of the workbench 1 and prevent deformation of the table surface due to excessive local stress during high-pressure extrusion, a support column 11 is installed on each side of the bottom of the workbench 1 corresponding to its opening area. The two support columns 11 are located on the left and right sides of the opening, respectively, and are arranged parallel to the original support legs 2. The length of the support column 11 is equal to that of the support leg 2, ensuring that the device is placed stably. The support column 11 directly bears part of the reaction force transmitted from the extrusion cylinder 5, effectively dispersing the load and improving the structural stability of the equipment during operation.

[0048] Example 4:

[0049] Combined with appendix Figures 1-2 A waste aluminum forming device, based on any one of the embodiments in Examples 1 to 3, specifically includes a connecting sleeve 3 and a telescopic cylinder 12 in its telescopic device structure. The connecting sleeve 3 is a hollow cylindrical component, its bottom firmly connected to the workbench 1 by bolts or other fasteners to form a stable installation base. The telescopic cylinder 12 is assembled inside the connecting sleeve 3. This telescopic cylinder 12 can be a hydraulic cylinder or a pneumatic cylinder, its cylinder body fixedly connected to the inner wall of the connecting sleeve 3, while the telescopic rod extends from the top of the connecting sleeve 3 to transmit power. The connecting plates on both sides of the extrusion cylinder 5 are not directly connected to the telescopic rod of the telescopic cylinder 12, but are correspondingly connected to the outer wall of the connecting sleeve 3. This allows the weight and working load of the extrusion cylinder 5 to be mainly borne by the connecting sleeve 3, and then transmitted to the support leg 2 through the workbench 1. This reduces the stress on the cylinder body of the telescopic cylinder 12, which helps extend the service life of the telescopic cylinder 12 and improves system reliability.

[0050] It should be noted that the connecting sleeve 3 has a clearance opening on its side wall corresponding to the oil inlet / outlet or air inlet / outlet pipe of the telescopic cylinder 12. This opening is used to avoid the fluid connection pipe of the telescopic cylinder 12, preventing the pipe from being squeezed or bent during installation or operation, and ensuring the normal power supply and signal transmission of the hydraulic or pneumatic system. This design takes into account both structural compactness and functional requirements, ensuring the long-term stable operation of the equipment.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
