Description
Technical Field
[0001] This utility model relates to the field of mold steel processing technology, specifically to a device for cleaning iron oxide from the surface of hot-working mold steel after quenching. Background Technology
[0002] Hot work die steel refers to alloy tool steel suitable for making dies for hot deformation processing of metals, such as hot forging dies, hot extrusion dies, die casting dies, and hot upsetting dies. Because hot work dies operate under high temperature and high pressure conditions for extended periods, the die material must possess high strength, hardness, and thermal stability, especially high thermal strength, thermal fatigue resistance, toughness, and wear resistance. Hot work die steels come in various shapes, mainly depending on their application and processing requirements, including flat plates, blocks, cylinders, and irregular shapes. Furthermore, after quenching, a layer of iron oxide scale forms on the surface of the hot work die steel. This iron oxide scale increases the surface roughness of the die, forming surface defects such as pitting and scale, reducing the surface quality of the die. These defects not only affect the appearance of the die but may also affect its performance and lifespan. Therefore, a device for cleaning iron oxide from the surface of quenched hot work die steel is proposed to address the aforementioned problems. Utility Model Content

[0020] In the embodiments, by Figure 1-4 Provided is a device for cleaning iron oxide from the surface of quenched hot work die steel, comprising a base plate 1, a bracket 2 mounted on the surface of the base plate 1 to support cylindrical hot work die steel of different diameters, a drive assembly 3 for driving the cylindrical hot work die steel to rotate, a moving assembly 4 mounted on the base plate 1, and an adjusting assembly 5 mounted on the moving end of the moving assembly 4, the movable end of the adjusting assembly 5 being equipped with a cleaning device 6 for removing iron oxide from the surface of the cylindrical hot work die steel. The quenched cylindrical hot work die steel is placed on the bracket 2, which is adaptable to die steel of different diameters. The die steel is stably supported by adjusting the slider 24 and locking nut 27 on the bracket 2. The drive assembly 3 is activated to drive the motor. 31 drives the rotating shaft 32 to rotate through the belt pulley transmission mechanism 33, thereby causing the mold steel supported on the bracket 2 to rotate, ensuring that the surface of the mold steel can be evenly exposed within the working range of the cleaning device 6. The moving component 4 drives the lead screw 43 to rotate through the servo motor 42, causing the moving plate 45 to slide along the slide bar 44, so that the cleaning device 6 can move along the axial direction of the mold steel. At the same time, the adjusting component 5 adjusts the angle and height of the cleaning device 6 through the extension and retraction of the electric push rod 51, ensuring that the cleaning device 6 can closely fit the surface of the mold steel. The stepper motor 61 in the cleaning device 6 drives the active roller 62 to rotate, driving the polishing sand belt 64 to operate. The polishing sand belt 64 contacts the rotating surface of the mold steel and removes the iron oxide scale on the surface through friction.
[0021] Reference Figure 1-4 The bracket 2 includes a base 21. Several bases 21 are fixedly installed on the surface of the base plate 1 and are equidistantly distributed along the axis. A first mounting seat 22 is fixedly installed on the base 21. A sliding groove 23 is provided on the base 21, and a slider 24 is slidably connected in the sliding groove 23. A second mounting seat 25 is provided on the slider 24. Rollers 26 are rotatably connected to both the first mounting seat 22 and the second mounting seat 25. A locking nut 27 is threadedly connected to the slider 24 and is disposed through the base 21. One end of the locking nut 27 abuts against the base 21.
[0022] With the above-described structure, the distance between the rollers 26 on the first mounting base 22 and the second mounting base 25 can be adjusted by the position of the sliding slider 24 in the groove 23, thereby accommodating cylindrical hot work die steels of different diameters. When the die steel is placed on the bracket 2, the rollers 26 contact the surface of the die steel, providing support and reducing friction. By rotating the locking nut 27, one end of it abuts against the base 21, thereby fixing the position of the slider 24 and ensuring that the die steel remains stable during the cleaning process without shaking or displacement.
[0023] Reference Figure 1-4The drive assembly 3 includes a drive motor 31 fixedly mounted on the base plate 1, a through-type rotating shaft 32 rotatably connected to the first mounting base 22, and a roller 26 on the first mounting base 22 is disposed on the outer surface of the rotating shaft 32. One end of the rotating shaft 32 is connected to the output end of the drive motor 31 through a belt pulley transmission mechanism 33.
[0024] With the above structural configuration, the drive motor 31 is the power source. When the drive motor 31 starts, its output end will drive the belt pulley transmission mechanism 33 to run and further drive the rotating shaft 32 to rotate. The roller 26 on the first mounting base 22 is set on the outer surface of the rotating shaft 32. Therefore, when the rotating shaft 32 rotates, it will drive the roller 26 to rotate synchronously, thereby realizing the self-rotation of the mold steel.
[0025] Reference Figure 1-4 The moving component 4 includes a frame 41 fixedly installed on the base plate 1, with an open top. A servo motor 42 is fixedly installed on one side surface of the frame 41. A lead screw 43 is provided at the output end of the servo motor 42 and is rotatably connected inside the frame 41. A slide bar 44 is provided at the top edge of the frame 41. A moving plate 45 is slidably connected to the outside of the slide bar 44, and a lead screw slider 46 adapted to the lead screw 43 is provided on one side surface of the moving plate 45.
[0026] With the above structural configuration, the output end of the servo motor 42 is connected to a lead screw 43, which is rotatably connected inside the frame 41. When the servo motor 42 is started, its output end will drive the lead screw 43 to rotate. When the lead screw 43 rotates, the lead screw slider 46 will move along the axial direction of the lead screw 43, thereby driving the moving plate 45 to slide along the slide bar 44. By controlling the rotation direction and speed of the servo motor 42, the movement direction and distance of the moving plate 45 can be precisely controlled, thereby realizing flexible adjustment of the position of the cleaning device 6 and ensuring that the cleaning device 6 can accurately align with the surface of the mold steel for cleaning.
[0027] Reference Figure 1-4 The adjustment component 5 includes an electric push rod 51 hinged to the surface of the movable plate 45. There are two electric push rods 51. The surface of the movable plate 45 is also hinged to a bracket 52. The end of the bracket 52 away from the movable plate 45 is hinged to the telescopic end of the electric push rod 51. A fixing frame 53 is fixedly installed on the bracket 52.
[0028] With the above-mentioned structural configuration, when the telescopic end of the electric push rod 51 telescopically moves, it will drive the bracket 52 to rotate around the hinge point between it and the moving plate 45. Since the bracket 52 is fixedly installed with a fixed frame 53, the fixed frame 53 will move closer to or further away from the mold steel as the bracket 52 rotates, thereby adjusting the position and posture of the cleaning device 6 installed on the fixed frame 53.
[0029] Reference Figure 1-4 The cleaning device 6 includes a stepper motor 61 fixedly mounted on a fixed frame 53. The output end of the stepper motor 61 is connected to a drive roller 62 via a coupling. The end of the drive roller 62 away from the stepper motor 61 is bearing connected to the fixed frame 53. Multiple driven rollers 63 are rotatably connected to the fixed frame 53. The outer surfaces of the multiple driven rollers 63 and the drive roller 62 are all connected to a polishing sand belt 64. Two telescopic cylinders 65 are symmetrically arranged on the fixed frame 53. The telescopic ends of the two telescopic cylinders 65 are rotatably connected to the two ends of the tension roller 66, respectively.
[0030] With the above structural setup, the stepper motor 61 serves as the power source. When the stepper motor 61 starts, its output end drives the active roller 62 to rotate. The end of the active roller 62 furthest from the stepper motor 61 is connected to the fixed frame 53 by a bearing to ensure rotational stability. When the active roller 62 rotates, it drives the polishing sand belt 64 to run between the active roller 62 and the driven roller 63. The running polishing sand belt 64 contacts the surface of the mold steel and removes the iron oxide scale on the surface of the mold steel through friction, thus achieving the cleaning operation. By controlling the extension and retraction length of the telescopic cylinder 65, the position of the tension roller 66 can be adjusted, thereby adjusting the tension of the polishing sand belt 64 to ensure that the polishing sand belt 64 maintains an appropriate tension during operation and improves the cleaning effect.
[0031] Reference Figure 1-4 The system includes a spray assembly 7 mounted on a fixed frame 53, which is used to uniformly spray polishing liquid onto the surface of cylindrical hot work die steel. The spray assembly 7 includes a solution tank 71 fixedly mounted on the fixed frame 53, and the solution tank 71 is wider at the top and narrower at the bottom. The bottom of the solution tank 71 is connected to a number of solenoid valves 72 that are evenly distributed, and the end of the solenoid valve 72 away from the solution tank 71 is connected to a nozzle 73.
[0032] With the above-described structure, the top of the solution tank 71 is open and equipped with a removable cover to prevent the polishing liquid from spilling. When the solenoid valve 72 is opened, the polishing liquid will flow out from the solution tank 71 and be evenly sprayed onto the surface of cylindrical hot work die steel through the nozzle 73. This ensures that the polishing liquid can cover all areas of the die steel surface, improve the cleaning effect, and work in conjunction with the cleaning device 6. The polishing liquid plays a lubricating and cooling role when the polishing belt 64 rubs against the die steel surface, while also helping to remove iron oxide scale, improving cleaning efficiency and the surface quality of the die steel.
[0033] Reference Figure 1-4 The bracket 52 is provided with a collection frame 8 located below the polishing sand belt 64;
[0034] With the above structural design, the collection box 8 can directly receive the waste chips and waste liquid that fall from the polishing sand belt 64 and the surface cleaning of the mold steel, reducing subsequent cleaning work and helping to improve the safety and hygiene of the working environment.
