Description

Technical Field

[0001] This application relates to the technical field of metal waste, and in particular to a metal waste recycling device. Background Technology

[0002] Currently available metal scrap recycling equipment generally has a simple structure, mainly focusing on simple collection and preliminary compression of scrap. For aluminum scrap, the process typically involves simple collection followed by compression, lacking pretreatment and sorting. This direct compression method results in scrap entering the pressing mechanism with varying and irregular shapes, significantly affecting the uniformity and success rate of the pressing process. Furthermore, existing pressing mechanisms often employ fixed pressing methods, unable to flexibly adapt to aluminum scrap of different shapes and thicknesses, leading to inconsistent quality and density of the compressed blocks. In the collection stage, the compressed blocks are simply piled together, neglecting the impact of block quality on subsequent processing.

[0003] Existing technologies have failed to effectively address the issues of poor uniformity and uneven density in aluminum scrap during the pressing process. This not only reduces the overall quality and stability of the pressed blocks but also increases the difficulty and cost of subsequent transportation, storage, and reprocessing. Utility Model Content

[0004] To address the issue that current metal scrap recycling devices, due to their inherent design characteristics, fail to effectively resolve the problems of poor uniformity and uneven density in aluminum scrap during the pressing process. This not only reduces the overall quality and stability of the pressed blocks but also increases the difficulty and cost of subsequent transportation, storage, and reprocessing. Therefore, this application provides a metal scrap recycling device.

[0005] The metal scrap recycling device provided in this application adopts the following technical solution: it includes a fixed base plate, a support plate opposite to the fixed base plate, a guide column disposed between the fixed base plate and the support plate, a fixed mold base fixedly connected to the fixed base plate, a pressure seat disposed on the upper end face of the fixed mold base, a movable mold base slidably connected to the guide column and disposed relative to the fixed mold base, a guide sleeve disposed on the movable mold base and adapted to the guide column, a hydraulic cylinder penetrating through the support plate and connected to the upper end face of the movable mold base, a pressure head disposed on the lower end face of the support plate, an elastic element disposed between the pressure head and the support plate, and a positioning assembly disposed between the pressure head and the pressure seat. The telescopic shaft of the hydraulic cylinder penetrates through the support plate and is connected to the movable mold base.

[0006] By adopting the above technical solution, the hydraulic cylinder pushes the moving mold base to move up and down, the guide column and guide sleeve ensure the smoothness and stability of the linear motion of the moving mold base, the positioning component limits the initial position of the pressure head, and the elastic element automatically adjusts the pressure of the pressure head according to the thickness of the metal scrap, thereby realizing an efficient and accurate metal scrap recycling process.

[0007] As a preferred embodiment, one end of the guide post is connected to the fixed base plate by a fixing bolt, and the other end of the guide post is also connected by a fixing bolt.

[0008] By adopting the above technical solution, the guide column is firmly connected to the fixed base plate and support plate by fixing bolts to form a stable guiding system, which enables the moving mold base to be accurately guided and move stably on the set path.

[0009] As a preferred embodiment, the guide sleeve and the moving mold base are connected by a fixing pin, and the inner wall of the guide sleeve is set as a smooth arc surface.

[0010] By adopting the above technical solution, the guide sleeve provides a smooth arc surface, allowing the moving mold base to move more smoothly in linear motion, reducing friction and ensuring the stability and accuracy of the motion. The moving mold base is connected to the guide sleeve by a fixing pin, thereby achieving precise alignment and stable linear motion. The guide post, through its cooperation with the guide sleeve, further enhances the guiding and stability of the moving mold base's linear motion, ensuring that the entire mechanical device operates efficiently and accurately during operation.

[0011] As a preferred embodiment, the moving mold base is provided with a connecting shaft at one end relative to the telescopic shaft, one end of the connecting shaft is fixedly connected to the moving mold base, and the other end of the connecting shaft is connected to the telescopic shaft.

[0012] By adopting the above technical solution, the moving mold base is responsible for executing the up-and-down movement of the pressure head to complete the pressing action in the molding process; the connecting shaft acts as a bridge between the two, ensuring that the moving mold base can move synchronously with the movement of the telescopic shaft; the telescopic shaft is driven by a hydraulic cylinder, and precise control of the moving mold base is achieved through extension and retraction. Thus, when the telescopic shaft of the hydraulic cylinder extends or retracts, it pushes the connecting shaft to move the moving mold base up and down, thereby realizing the opening and closing of the pressure head and pressure base, and accurately completing various actions in the molding process.

[0013] As a preferred embodiment, the elastic element includes sliding rods respectively disposed at the four corners of the pressure head, sliding holes disposed on the upper end face of the moving mold base and adapted to the sliding rods, adjusting springs disposed on the outer periphery of the sliding rods, and fixing screws disposed at the connection between the sliding rods and the pressure head, wherein the fixing screws pass through the connection between the sliding rods and the pressure head.

[0014] By adopting the above technical solution, the sliding rod in the elastic component provides support at the four corners of the pressure head, effectively transmitting and dispersing the pressure generated by the pressure head during the part-making process, ensuring that the pressure head is stably perpendicular to the moving mold base. The sliding hole is pre-set on the upper surface of the moving mold base, matching the sliding rod, allowing it to slide freely and ensuring smooth movement of the pressure head during pressing. The adjusting spring, sleeved on the outer circumference of the sliding rod, provides additional elastic buffering, making the pressure head more stable during pressing, reducing impact and vibration, and facilitating automatic adjustment of the pressure head's pressing force according to the thickness of the metal scrap. The fixing screw connects the sliding rod and the pressure head, ensuring a stable and reliable connection during part-making, and also allowing easy adjustment of the sliding rod's position to accommodate pressure heads of different sizes.

[0015] As a preferred embodiment, one end of the adjusting spring is fixedly connected to the pressure head, and the other end of the adjusting spring is fixedly connected to the moving mold base.

[0016] By adopting the above technical solution, when the thickness of the metal scrap is small, the distance the pressure head descends is small, the compression of the adjusting spring is also small, and a smaller pressing force is provided; conversely, when the thickness of the metal scrap is large, the distance the pressure head descends increases, the compression of the adjusting spring also increases accordingly, thereby providing a larger pressing force and achieving the effect of automatically adjusting the pressing force.

[0017] As a preferred embodiment, the sliding hole is configured as a through hole, and the inner wall of the sliding hole is configured as a smooth arc surface.

[0018] By adopting the above technical solution, the sliding hole is used as a through hole. Its inner wall is smooth and arc-shaped, and its main function is to provide guidance for the sliding rod, ensuring that the sliding rod moves smoothly within a defined path. The sliding rod can slide freely in the sliding hole, and the smooth arc surface reduces the friction and movement resistance between them, making the sliding process more stable.

[0019] As a preferred embodiment, the positioning component includes positioning blocks fixedly disposed on both sides of the fixed mold base and positioning grooves disposed on both sides of the moving mold base and adapted to the positioning blocks. The outer diameter of the positioning block is slightly larger than the inner diameter of the positioning groove, and the upper end surface of the positioning block and the upper end surface of the pressure base are disposed on the same horizontal plane.

[0020] By adopting the above technical solution, the outer diameter of the positioning block is slightly larger than the inner diameter of the positioning groove, ensuring accurate positioning of the moving mold base during the closing process and preventing displacement. The upper end face of the positioning block and the upper end face of the pressure seat are on the same horizontal plane, enabling the moving mold base to accurately align with the pressure seat when closed, improving assembly accuracy. The inner design of the positioning block facilitates the guidance of scrap metal into the pressing area, avoiding material blockage between the pressure head and the pressure seat, thereby ensuring a smooth pressing process.

[0021] As a preferred embodiment, the device also includes a vibration motor disposed within the cavity of the pressure base, the output shaft of which is disposed relative to the pressure base.

[0022] By adopting the above technical solution, the vibration motor makes the metal scrap more evenly distributed during the pressing process, avoiding local over-compression or uneven density.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. The fixed base plate and support plate provide a stable support foundation, the guide column ensures that the moving mold base moves in a straight line, the fixed mold base fixes the position of the pressure seat, and the pressure seat is used to place metal scrap;

[0025] 2. The moving mold base and the fixed mold base move relative to each other, and the up and down movement is achieved by the power provided by the hydraulic cylinder. The guide sleeve and the guide column cooperate to increase the stability of the movement.

It includes a fixed base plate 2, a support plate 1 opposite to the fixed base plate 2, a guide column 41 disposed between the fixed base plate 2 and the support plate 1, a fixed mold base 32 fixedly connected to the fixed base plate 2, a pressure seat 62 disposed on the upper surface of the fixed mold base 32, a movable mold base 31 slidably connected to the guide column 41 and disposed relative to the fixed mold base 32, a guide sleeve 42 disposed on the movable mold base 31 and adapted to the guide column 41, a hydraulic cylinder 5 penetrating through the support plate 1 and connecting to the upper surface of the movable mold base 31, and a pressure head 61 disposed on the lower surface of the support plate 1. An elastic element is provided between the pressure head 61 and the support plate 1, and a positioning component is provided between the pressure head 61 and the pressure base 62. The telescopic shaft of the hydraulic cylinder 5 passes through the support plate 1 and connects to the moving mold base 31. In this utility model, the hydraulic cylinder 5 pushes the moving mold base 31 to move up and down. The guide column 41 and the guide sleeve 42 ensure the smoothness and stability of the linear movement of the moving mold base 31. The positioning component limits the initial position of the pressure head 61. The elastic element automatically adjusts the pressure of the pressure head 61 according to the thickness of the metal scrap, thereby realizing an efficient and accurate metal scrap recycling process.

[0035] Please refer to the details. Figure 1 , Figure 2 and Figure 3 One end of the guide post 41 is connected to the fixed base plate 2 by a fixing bolt, and the other end of the guide post 41 is also connected by a fixing bolt. The guide post 41 is firmly connected to the fixed base plate 2 and the support plate 1 by the fixing bolt, forming a stable guiding system, so that the moving mold base 31 can be accurately guided and move stably on the set path.

[0036] Please refer to the details. Figure 1 and Figure 2The guide sleeve 42 is connected to the moving mold base 31 by a fixing pin, and the inner wall of the guide sleeve 42 is set as a smooth arc surface. The function of the guide sleeve 42 is to provide a smooth arc surface so that the moving mold base 31 can move more smoothly in linear motion, reduce friction, and ensure the stability and accuracy of the motion. The moving mold base 31 is connected to the guide sleeve 42 by the fixing pin, thereby achieving precise alignment and stable linear motion. The guide post 41, through its cooperation with the guide sleeve 42, further enhances the guidance and stability of the linear motion of the moving mold base 31, ensuring that the entire mechanical device can operate efficiently and accurately during the working process. The working principle is: when the moving mold base 31 is in linear motion, the guide post 41 is inserted into the smooth arc surface of the guide sleeve 42, achieving precise guidance and positioning, while reducing friction during the movement, ensuring the smoothness and stability of the linear motion of the moving mold base 31.

[0037] Please refer to the details. Figure 2 and Figure 3 A connecting shaft 51 is provided at one end of the moving mold base 31 relative to the telescopic shaft. One end of the connecting shaft 51 is fixedly connected to the moving mold base 31, and the other end of the connecting shaft 51 is connected to the telescopic shaft. The moving mold base 31 is responsible for executing the up-and-down movement of the pressure head 61 to complete the pressing action in the molding process. The connecting shaft 51 acts as a bridge between the two, ensuring that the moving mold base 31 can move synchronously with the movement of the telescopic shaft. The telescopic shaft is driven by the hydraulic cylinder 5, and precise control of the moving mold base 31 is achieved through extension and retraction. Thus, when the telescopic shaft of the hydraulic cylinder 5 extends or retracts, it pushes the connecting shaft 51 to drive the moving mold base 31 to move up and down, thereby realizing the opening and closing of the pressure head 61 and the pressure seat 62, and accurately completing various actions in the molding process.

[0038] Please refer to the details. Figure 1 , Figure 4 and Figure 5The elastic element includes sliding rods 71 ​​respectively disposed at the four corners of the pressure head 61, sliding holes 312 disposed on the upper end face of the moving mold base 31 and adapted to the sliding rods 71, adjusting springs 711 disposed on the outer periphery of the sliding rods 71, and fixing screws 8 disposed at the connection between the sliding rods 71 ​​and the pressure head 61. The fixing screws 8 pass through the connection between the sliding rods 71 ​​and the pressure head 61. The sliding rods 71 ​​in the elastic element play a supporting role at the four corners of the pressure head 61, which can effectively transmit and disperse the pressure generated by the pressure head 61 during the part making process, and ensure that the pressure head 61 is stably perpendicular to the moving mold base 31. The sliding holes 312 are pre-set on the upper end face of the moving mold base 31 and match the sliding rods 71, so that the sliding rods 71 ​​can slide freely, ensuring that the pressure head 61 can move smoothly during the pressing action. An adjusting spring 711 is sleeved around the outer periphery of the sliding rod 71, providing additional elastic cushioning. This allows the pressure head 61 to move more smoothly during pressing, reducing impact and vibration, and facilitating automatic adjustment of the pressure force applied by the pressure head 61 according to the thickness of the metal scrap. A fixing screw 8 connects the sliding rod 71 and the pressure head 61, ensuring a stable and reliable connection during the manufacturing process. It also allows for easy adjustment of the position of the sliding rod 71 to accommodate different sized pressure heads 61. The working principle is as follows: when the pressure head 61 presses down, the sliding rod 71 moves freely through the sliding hole 312, while the adjusting spring 711 provides elastic support, reducing vibration and impact, and facilitating automatic adjustment of the pressure force applied by the pressure head 61 according to the thickness of the metal scrap. The fixing screw 8 ensures a secure connection between the sliding rod 71 and the pressure head 61. The entire process is completed under stable and precise conditions, ensuring the quality of the manufactured parts and the long service life of the mold.

[0039] Please refer to the details. Figure 4 and Figure 5 One end of the adjusting spring 711 is fixedly connected to the pressure head 61, and the other end of the adjusting spring 711 is fixedly connected to the moving mold base 31. When the thickness of the metal scrap is small, the pressure head 61 descends a small distance, and the compression of the adjusting spring 711 is also small, providing a small pressing force. Conversely, when the thickness of the metal scrap is large, the pressure head 61 descends a larger distance, and the compression of the adjusting spring 711 is also increased accordingly, thereby providing a larger pressing force and achieving the effect of automatically adjusting the pressing force.

[0040] Please refer to the details. Figure 1 , Figure 4 and Figure 5 The sliding hole 312 is configured as a through hole, and its inner wall is a smooth arc surface. The sliding hole 312 serves as a through hole, and its smooth, arc-shaped inner wall primarily guides the sliding rod 71, ensuring its smooth movement within a defined path. The sliding rod 71 can slide freely within the sliding hole 312, and the smooth arc surface reduces friction and resistance, making the sliding process more stable.

[0041] Please refer to the details. Figure 1 and Figure 2 The positioning components include positioning blocks 321 fixedly mounted on both sides of the fixed mold base 32 and positioning grooves 311 mounted on both sides of the moving mold base 31 that are adapted to the positioning blocks 321. The outer diameter of the positioning blocks 321 is slightly larger than the inner diameter of the positioning grooves 311. The upper end face of the positioning blocks 321 and the upper end face of the pressure base 62 are on the same horizontal plane. The slightly larger outer diameter of the positioning blocks 321 ensures that the moving mold base 31 can be accurately positioned during the closing process, preventing displacement. The fact that the upper end face of the positioning blocks 321 and the upper end face of the pressure base 62 are on the same horizontal plane allows the moving mold base 31 to accurately align with the pressure base 62 when closed, improving assembly accuracy. The inner design of the positioning blocks 321 facilitates the guidance of scrap metal into the pressing area, avoiding material blockage between the pressure head 61 and the pressure base 62, thereby ensuring a smooth pressing process. The working principle is as follows: During the pressing process, the positioning groove 311 on the moving mold base 31 is tightly engaged with the positioning block 321 on the fixed mold base 32. By controlling the movement of the moving mold base 31, the pressure head 61 is accurately aligned with the pressing area. At the same time, the special design of the inner side of the positioning block 321 guides the metal scrap into the pressing area. The whole process ensures precise force application and positioning accuracy during each pressing.

[0042] Please refer to the details. Figure 1 It also includes a vibration motor installed inside the pressure base 62. The output shaft of the vibration motor is positioned relative to the pressure base 62. The vibration motor vibrates to make the metal scrap more evenly distributed during the pressing process, avoiding local over-compression or uneven density. Its working principle is: the vibration generated by the vibration motor is transmitted to the pressure base 62 and the pressure head 61, so that the metal scrap is subjected to uniform compressive force during the pressing process, ensuring that each part of the metal scrap is fully compressed, thereby improving the uniformity and efficiency of the entire pressing process.

[0043] The implementation principle of the metal scrap recycling device in this application embodiment is as follows: During use, the hydraulic cylinder 5 pushes the moving mold base 31 to move up and down. The guide column 41 and the guide sleeve 42 ensure the smoothness and stability of the linear movement of the moving mold base 31. During the pressing process, the positioning groove 311 on the moving mold base 31 is tightly engaged with the positioning block 321 on the fixed mold base 32. By controlling the movement of the moving mold base 31, the pressure head 61 is accurately aligned with the pressing area. At the same time, the special design of the inner side of the positioning block 321 guides the metal scrap into the pressing area. The whole process ensures precise force application and positioning accuracy during each pressing. When the thickness of the metal scrap is small, the distance the pressure head 61 descends is small, and the compression of the adjusting spring 711 is also small, providing a small pressing force. Conversely, when the thickness of the metal scrap is large, the distance the pressure head 61 descends increases, and the compression of the adjusting spring 711 also increases accordingly, thereby providing a larger pressing force and achieving the effect of automatically adjusting the pressing force.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
