Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and automation control technology, specifically to a laser cutting device for scrap steel sorting and recycling. Background Technology

[0002] In the steel industry, scrap steel recycling is a key link in achieving resource recycling, reducing production costs, and minimizing environmental pollution. With the annual increase in steel production and increasingly stringent environmental protection requirements, efficient and precise scrap steel sorting and recycling technologies are becoming increasingly important.

[0003] In traditional scrap steel sorting and recycling processes, scrap steel is mostly cut using flame cutting or mechanical cutting methods. Flame cutting utilizes the high temperature generated by the combustion of a mixture of fuel gas and oxygen to melt the steel and achieve cutting. While the equipment is relatively simple, it has many drawbacks. During the cutting process, uneven flame temperature distribution easily leads to uneven cut surfaces and a large heat-affected zone, altering the metallographic structure of the steel and reducing its recycling value. Furthermore, flame cutting consumes large amounts of fuel gas and oxygen, resulting in high costs, and also generates significant amounts of smoke and harmful gases, causing serious environmental pollution.

[0004] Mechanical cutting primarily uses cutting tools to slice scrap steel. While this method offers relatively high cutting precision, it suffers from severe tool wear and frequent replacements for scrap steel with complex shapes, significant thickness, or high hardness, increasing equipment maintenance costs and downtime. Furthermore, mechanical cutting is inefficient and cannot meet the production demands of large-scale scrap steel sorting and recycling.

[0005] In summary, traditional flame cutting and mechanical cutting technologies suffer from poor cutting quality, high cost, low efficiency, and significant environmental pollution during scrap steel sorting and recycling. These issues make them unsuitable for the development requirements of the modern scrap steel recycling industry, and a new cutting technology is urgently needed to address these problems. Utility Model Content

[0006] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a laser cutting device for scrap steel sorting and recycling. By combining a high-precision moving mechanism with a stable cutting component, it can achieve precise positioning and cutting of scrap steel in the X, Y, and Z directions. This solves the problems of low cutting accuracy, low efficiency, and significant damage to scrap steel material in traditional cutting methods in scrap steel sorting and recycling, thereby improving the quality and efficiency of scrap steel recycling, reducing production costs, and promoting the technological upgrading of the scrap steel recycling industry.

[0007] Technical Solution: This utility model provides a laser cutting device for scrap steel sorting and recycling, comprising: a worktable on which scrap steel is placed; a frame mounted on the worktable; a cutting assembly including a laser head facing the scrap steel on the worktable; and a moving mechanism mounted on the frame to drive the cutting assembly to move in the X, Y, and Z directions. The worktable provides a stable platform for laser cutting, facilitating the cutting of the scrap steel. The laser head, facing the scrap steel on the worktable, emits a laser to cut the scrap steel, thus processing it to meet the needs of sorting and recycling. The moving mechanism, mounted on the frame, drives the cutting assembly to move in the X, Y, and Z directions, allowing the laser head to be flexibly adjusted in three-dimensional space. This enables precise cutting of scrap steel of different positions and shapes on the worktable, improving the flexibility and applicability of the cutting process.

[0008] Furthermore, in a laser cutting device for scrap steel sorting and recycling according to this application, the cutting assembly further includes a mounting base. The mounting base is vertically arranged, with its lower end detachably connected to the laser head and its upper end connected to a cooling fan. The vertical arrangement of the mounting base and its detachable connection to the laser head facilitates the installation, disassembly, and maintenance of the laser head. This allows for quick operation and reduces downtime in case of laser head malfunction or replacement. The cooling fan at the upper end of the mounting base addresses the issue that heat generated by the laser head during laser cutting can affect its performance and lifespan. The cooling fan effectively removes the heat generated by the laser head, ensuring it operates at a suitable temperature.

[0009] Furthermore, this application discloses a laser cutting device for scrap steel sorting and recycling. The frame includes four uprights, a pair of horizontal bars, a pair of vertical bars, a transverse guide bar, and a longitudinal guide bar. The uprights are vertically mounted on a worktable, and their upper ends are connected to the pair of horizontal bars and the pair of vertical bars via connectors. The pair of horizontal bars and vertical bars form a rectangle. The transverse guide bar is connected to the vertical bars at both ends and moves along the Y-direction. The longitudinal guide bar is connected to the horizontal bars at both ends and moves along the X-direction. The transverse guide bar and longitudinal guide bar are vertically arranged.

The uprights are vertically mounted on the worktable, and their upper ends are connected to the horizontal bars and vertical bars via connectors, forming a stable rectangular frame structure that provides robust support for the entire cutting device and ensures the stability of the equipment during operation.

[0010] Furthermore, in a laser cutting device for scrap steel sorting and recycling, the moving mechanism of this application includes four first driving components. These first driving components are respectively located at both ends of the transverse and longitudinal moving rods, and are used to drive the transverse moving rod to move along the longitudinal rod in the Y direction and to drive the longitudinal moving rod to move along the transverse rod in the X direction. The four first driving components are evenly distributed at both ends of the transverse and longitudinal moving rods, providing stable and balanced power, ensuring the smooth movement of the transverse and longitudinal moving rods, reducing vibration during equipment operation, and improving the reliability and stability of the equipment.

[0011] Furthermore, in a laser cutting device for scrap steel sorting and recycling, the first driving component includes a first driving motor, a first claw, and a plurality of first pulleys. The first driving motor and the first pulleys are mounted on the first claw. When the transverse rod moves along the longitudinal rod, the first claw clamps onto the longitudinal rod via the first pulleys, and the output end of the first driving motor drives the first pulleys to roll on the longitudinal rod via a belt. When the longitudinal rod moves along the transverse rod, the first claw clamps onto the transverse rod via the first pulleys, and the output end of the first driving motor drives the first pulleys to roll on the transverse rod via a belt.

[0012] Furthermore, in a laser cutting device for scrap steel sorting and recycling according to this application, the moving mechanism further includes a second driving assembly. The cutting assembly is mounted on the second driving assembly, which is located at the intersection of the transverse and longitudinal rods. The second driving assembly drives the cutting assembly to move in the Z-direction and is tumbledly connected to the transverse and longitudinal rods. The second driving assembly of the moving mechanism is located at the intersection of the transverse and longitudinal rods, and the cutting assembly is mounted on the second driving assembly. The second driving assembly can drive the cutting assembly to move in the Z-direction, enabling vertical position adjustment of the laser head to adapt to the cutting requirements of scrap steel of different thicknesses. The tumbled connection between the second driving assembly and the transverse and longitudinal rods ensures smooth movement during the process.

[0013] Furthermore, in a laser cutting device for scrap steel sorting and recycling, the second driving component includes a second driving motor, a second gripper, a third gripper, a fourth gripper, a plurality of second pulleys, a threaded rod, a first guide rod, a second guide rod, and a connecting clamp. The second pulleys are mounted on the second, third, and fourth grippers. The first and second guide rods are arranged parallel to each other along the Z-direction. The mounting base is mounted on the first and second guide rods via clamps. The second gripper is simultaneously clamped onto the transverse rod and the first guide rod via the second pulleys and can roll along the transverse rod and the first guide rod. The third gripper is connected to the second pulleys via the second pulleys. The pulley is simultaneously clamped on the longitudinal rod and the second guide rod, and can roll along the longitudinal rod and the second guide rod; the fourth gripper is simultaneously clamped on the first guide rod and the second guide rod via the second pulley, and can roll along the first guide rod and the second guide rod; the second gripper and the third gripper are connected, and the second gripper and the fourth gripper are connected; the first guide rod and the second guide rod pass through the connecting hoop, the connecting hoop is located at the upper end of the first guide rod and the second guide rod, and a second drive motor is installed on it. The output end of the second drive motor is connected to a threaded rod, the threaded rod is arranged along the Z direction, and is sequentially threadedly connected to the connecting hoop, the fourth gripper, the third gripper, and the second gripper. The first and second guide rods are arranged parallel to each other along the Z-direction. The mounting base is installed on the first and second guide rods via clamps, providing vertical guidance and support for the cutting assembly. The second gripper is simultaneously clamped onto the transverse guide rod and the first guide rod via a second pulley, and can roll along the transverse guide rod and the first guide rod. The third gripper is simultaneously clamped onto the longitudinal guide rod and the second guide rod via a second pulley, and can roll along the longitudinal guide rod and the second guide rod. The fourth gripper is simultaneously clamped onto the first and second guide rods via a second pulley, and can roll along the first and second guide rods. This achieves flexible rolling connection on different rods, ensuring the coordination of the cutting assembly with other components during Z-direction movement. For stability, the second and third grippers are connected, as are the second and fourth grippers, which interconnect the different grippers and ensure the linkage and stability of the overall structure. The first and second guide rods pass through the connecting hoop, which is located at the upper end of the first and second guide rods. A second drive motor is installed on the hoop, and the output end of the second drive motor is connected to a threaded rod. The threaded rod is set along the Z direction and is sequentially threaded to the connecting hoop, the fourth gripper, the third gripper, and the second gripper. The second drive motor drives the threaded rod to rotate, which in turn drives the relative movement of each gripper in the Z direction, ultimately achieving precise movement of the cutting component in the Z direction.
