Description

Technical Field

[0001] This invention relates to the field of magnesium alloy production technology, and in particular to a polishing apparatus for magnesium alloy production. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as the base and other elements. Magnesium alloys are characterized by high specific strength, high specific modulus of elasticity, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloys, and good resistance to corrosion by organic matter and alkalis. It is the lightest of the practical metals. Therefore, magnesium alloys are widely used in aviation, aerospace, automotive, 3C products and military industries.

[0003] Most existing magnesium alloy materials are in the form of plates and rods. However, existing magnesium alloy polishing equipment can cause a large amount of heat to accumulate in certain areas during the fixed polishing process, posing a safety risk of overheating and combustion of the magnesium alloy (magnesium powder is flammable and explosive). Traditional cooling methods often involve spraying coolant, but the liquid may react chemically with the magnesium alloy, or contaminate the surface of the plate, and subsequent treatment is troublesome. Summary of the Invention

[0013] Optionally, a first limiting ring is provided at the position of the heat-conducting rod below the mounting shell and above the partition plate. A spring is provided between the first limiting ring and the partition plate, and the spring is sleeved on the outer surface of the heat-conducting rod.

[0019] The beneficial effects of this invention are as follows: 1. The magnesium alloy to be polished is placed between the supports. The second driving component is activated, causing the fixing part to move along the first sliding groove in the opposite direction, thereby fixing and clamping the magnesium alloy and ensuring that the magnesium alloy can move smoothly. The first hydraulic cylinder is activated, causing the alignment component to slide on the sliding frame, thereby transporting the magnesium alloy from the front of the polishing cabinet to below the polishing disc. After the magnesium alloy is placed on the alignment component, it slides along the sliding frame, and the alignment component centers the magnesium alloy sheet. The clamping component, driven by the first driving component, clamps the two sets of modules towards the center, ensuring stability and preventing deviation when polishing the magnesium alloy sheet, thus improving work efficiency.

[0020] 2. During the polishing process, the heat generated by the magnesium alloy can be quickly conducted through multiple sets of heat-conducting rods. The flowing cooling water in the water-containing cavity can cool and absorb heat from the lower end of the heat-conducting rods in a timely manner, forming an efficient heat dissipation cycle. This effectively reduces the heat accumulation of the magnesium alloy sheet, significantly reduces the risk of thermal combustion caused by high temperature during polishing, ensures processing safety, and avoids the impact of high temperature on the performance of the magnesium alloy material.

[0021] 3. Start the connector to move the two sets of modules, the moving frame and the first drive component toward the magnesium alloy. When the second roller contacts both ends of the magnesium alloy, close the connector to lock and fix the magnesium alloy, ensuring that the workpiece does not shift or shake during the polishing process, and ensuring the uniformity and precision of the polished surface. After polishing is completed, the workpiece is quickly released by the reverse action of the component, creating convenient conditions for the unloading process. Attached Figure Description

[0039] This embodiment provides a polishing device for magnesium alloy production, such as... Figures 1-3 As shown, it includes a polishing cabinet 1, a polishing disc 2, a mounting bracket 11, a leveling assembly 3, a heat absorption assembly 5, a clamping assembly 4, and a cleaning box 6; a polishing motor (not shown in the figure) is fixedly installed on the top of the polishing cabinet 1, and the output shaft of the polishing motor passes through the top of the polishing cabinet 1 and is fixed coaxially with the polishing disc 2. The polishing motor can achieve stepless speed regulation (speed range 500-3000r / min); a cabinet door is hinged to the front of the polishing cabinet 1.

[0040] Among them, such as Figure 4 and Figure 5 As shown, the mounting bracket 11 is fixedly installed inside the polishing cabinet 1. A fixed beam 12 is fixedly installed on the mounting bracket 11 perpendicular to the sliding direction of the alignment component 3. A sliding frame 31 is fixedly installed above the fixed beam 12. The sliding frame 31 consists of a connecting plate 311 and two crossbeams 312. The connecting plate 311 is fixedly connected to the ends of the two crossbeams 312. The fixed beam 12 is fixedly connected to the crossbeams 312. A third groove is provided on the inner side of the crossbeams 312 to provide a guide track for the sliding of the alignment component 3. The alignment component 3 slides along the third groove on the sliding frame 31, thereby transporting the magnesium alloy from the front of the polishing cabinet 1 to below the polishing disc 2. The alignment component 3 centers the magnesium alloy sheet, ensuring that the magnesium alloy sheet does not shift forward or backward.

[0041] Specifically, such as Figures 6-7 As shown, the alignment assembly 3 includes an alignment base 32, a sliding plate 35, and a fixing part 34. The sliding plate 35 is slidably mounted on the sliding frame 31. A conveying cylinder 313 is provided between the connecting plate 311 and the sliding plate 35. The top of the sliding plate 35 is connected to the alignment base 32 via a telescopic column 36. A first sliding groove 33 is provided above the alignment base 32, and a second driving component 38 is provided inside the alignment base 32. Figure 8 As shown, the second driving component 38 includes a second motor 381 and a second double-threaded screw 382. One end of the leveling seat 32 is fixedly connected to the second motor 381, and the output shaft of the second motor 381 is fixedly connected to the second double-threaded screw 382. A fixing part 34 is threadedly connected to the second double-threaded screw 382. Specifically, the fixing part 34 includes a fixing block 341 and a bracket 342. Two sets of fixing blocks 341 are threadedly connected to the second double-threaded screw 382. The top of the fixing block 341 is fixedly connected to the bracket 342. The bracket 342 passes through the first sliding groove 33, and the top left and right ends of the bracket 342 are rotatably equipped with first rollers 343. The axis of the first rollers 343 is perpendicular to the moving direction of the fixing part 34. When it is necessary to clamp the magnesium alloy, the second motor 381 is started, which drives the fixing block 341 to move on the second double-threaded screw 382. The bracket 342 is fixedly connected to the fixing block 341, so the bracket 342 moves in the opposite direction along the first sliding groove 33. The magnesium alloy is placed between the two sets of brackets 342, and the magnesium alloy is fixed and clamped by the first rollers 343 on both sides, thus straightening the offset magnesium alloy plate. Figure 9 As shown, sliding wheels 37 are evenly distributed at the bottom of the sliding plate 35, and the sliding wheels 37 are embedded in the third sliding groove; when the conveying cylinder 313 is started, the sliding wheels 37 roll in the third sliding groove, driving the entire aligning assembly 3 to slide along the sliding frame 31.

[0042] like Figure 10-12 As shown, the clamping assembly 4 is located behind the aligning assembly 3 and below the polishing disc 2. It includes a connector 41, a moving frame 45, and two sets of modules 42. One end of the connector 41 is fixedly connected to the side wall of the polishing cabinet 1, and the other end of the connector 41 is connected to the moving frame 45. A first driving member 44 is provided on the moving frame 45. The two sets of modules 42 are arranged vertically opposite each other. The side of the first driving member 44 away from the connector 41 is connected to the two sets of modules 42, and the first driving member 44 drives the two sets of modules 42 to move relative to each other. Specifically, the module 42 consists of a fixed frame 421 and a mounting block 424. The fixed frame 421 has two second protrusions 423 on the side facing the first driving member 44, and a first protrusion 422 is provided between the two second protrusions 423.

[0043] like Figure 11As shown, the movable frame 45 consists of two uprights 451 and two fixed plates 452. The inner sidewalls of the two uprights 451 are provided with second sliding grooves 454, and a first protrusion 422 is slidably disposed within the second sliding grooves 454. The fixed plates 452 are fixedly connected to the ends of the uprights 451, and a mounting hole 453 is provided at the center of the fixed plates 452. The first driving component 44 includes a first motor 49 and a first double-threaded screw 47. The first motor 49 is fixed to the outside of one of the fixed plates 452, and its output shaft rotates through the mounting hole 453 and is coaxially fixed to one end of the first double-threaded screw 47. The other end of the first double-threaded screw 47 is rotatably connected to the inside of the other fixed plate 452 via a bearing. The first double-threaded screw 47 is threadedly connected to the second protrusion 423. When it is necessary to clamp the magnesium alloy, the first motor 49 is started, which drives the first double-threaded screw 47 to rotate, thereby driving the two modules 42 to move in opposite directions through the second protrusion 423, and locking and fixing the outer surface of the magnesium alloy.

[0044] Furthermore, an installation frame 455 is fixedly installed between the two columns 451. Several second rollers 456 are evenly rotatably installed inside the installation frame 455. The axis of the second rollers 456 is horizontally arranged, and their tops are flush with the clamping surface of the module 42. They are used to support the magnesium alloy plate and assist its lateral movement.

[0045] In one embodiment, the connector 41 is a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to the column 451 via an arc-shaped plate 48. Two sets of symmetrically arranged telescopic components 46 are also connected between the fixed plate 452 and the side wall of the polishing cabinet 1. Each telescopic component 46 consists of a telescopic sleeve 462 and a telescopic rod 461. One end of the telescopic sleeve 462 is fixedly connected to the side wall of the polishing cabinet 1, and the other end of the telescopic sleeve 462 is slidably connected to the telescopic rod 461. The telescopic rod 461 is fixedly connected to the upper fixed plate 452 of the moving frame 45. By activating the connector 41 (hydraulic cylinder), the telescopic rod 461 slides within the telescopic sleeve 462, thereby causing the two sets of modules 42, the moving frame 45, and the first driving component 44 to move left and right. The telescopic component 46 ensures smooth movement.

[0046] like Figure 13-14As shown, the heat absorption component 5 is fixedly installed at the rear end of the aligning component 3, including a mounting shell 51; a partition plate 515 is fixedly installed inside the mounting shell 51, and the partition plate 515 is welded and sealed to the inner wall of the mounting shell 51. The lower end of the partition plate 515 is a water-containing cavity 516, and the water-containing cavity 516 is provided with an inlet 518 with a quick connector and an outlet 517 on both sides respectively; a number of heat-conducting rods 512 (made of copper) are slidably installed inside the mounting shell 51, and a guide sleeve is fixed at the corresponding position on the top of the mounting shell 51. A sealing guide hole is provided at the corresponding position on the partition plate 515. The heat-conducting rods 512 pass through the guide sleeve and the sealing guide hole in sequence, with one end passing through the top of the mounting shell 51 and contacting the magnesium alloy plate, and the other end passing through the partition plate 515 and located in the water-containing cavity 516. The heat-absorbing component 5 rises synchronously with the leveling base 32, and the upper ends of multiple sets of heat-conducting rods 512 elastically adhere to the lower surface of the magnesium alloy sheet. During polishing, the heat generated by the magnesium alloy sheet is transferred through the multiple sets of heat-conducting rods 512. The cooling water flowing in the water chamber 516 cools and absorbs heat from the lower ends of the heat-conducting rods 512, thereby cooling the magnesium alloy sheet, reducing heat accumulation, and lowering the risk of thermal combustion of the magnesium alloy during polishing. The heat-absorbing component 5 is fixedly connected to the rear of the leveling base 32 and can rise and fall synchronously with the leveling base 32.

[0047] Specifically, a first limiting ring 514 is fixedly installed inside the mounting shell 51 and above the partition plate 515 for the heat-conducting rod 512. A spring 513 is sleeved between the first limiting ring 514 and the partition plate 515. A fluororubber sealing ring is provided at the connection position between the heat-conducting rod 512 and the partition plate 515, and a second limiting ring 519 is provided at the bottom end of the heat-conducting rod 512. The spring 513 provides a continuous and independent upward elastic force for all heat-conducting rods 512. The first limiting ring 514 limits the upward movement height of the heat-conducting rod 512, and the second limiting ring 519 limits the downward movement of the heat-conducting rod 512. This design ensures that no matter how microscopically uneven the bottom surface of the magnesium alloy plate is, the upper end of all heat-conducting rods 512 can maintain good contact with it, forming an efficient heat conduction path.

[0048] In one embodiment, the bottom of the mounting bracket 11 is provided with a positioning groove, and the cleaning box 6 is embedded in the positioning groove for fixing, so as to collect the debris that falls during the polishing of the magnesium alloy sheet and facilitate cleaning.

[0049] The working principle of this invention is as follows: First, the magnesium alloy to be polished is placed between two sets of supports 342. The second motor 381 is started, driving the fixing block 341 to move on the second double-threaded screw 382. The support 342 is fixedly connected to the fixing block 341, so the support 342 moves in opposite directions along the first slide groove 33. The magnesium alloy is fixed and clamped by the first rollers 343 on both sides. The first rollers 343 can adjust the position of the magnesium alloy to straighten the magnesium alloy plate. After the magnesium alloy is fixed, the conveying cylinder 313 is started, driving the sliding plate 35 to slide in the third slide groove through the sliding wheel 37, transporting the magnesium alloy to the bottom of the clamping assembly 4. Then, the... The telescopic column 36 lifts the leveling seat 32 and the magnesium alloy plate upwards. Then, the connecting component 41 (hydraulic cylinder) is activated, moving the two modules 42, the moving frame 45, and the first driving component 44 towards the magnesium alloy. When the second roller 456 contacts both ends of the magnesium alloy, the connecting component 41 closes. Next, the first motor 49 is activated, rotating the first double-threaded screw 47, which, through the second protrusion 423, moves the two modules 42 in opposite directions, locking and securing the magnesium alloy. Then, the conveying cylinder 313 is activated, resetting the leveling seat 32 and the sliding plate 35 to their initial positions. At this point, the polishing motor is activated, rotating the polishing disc 2 to polish the surface of the magnesium alloy. During polishing, the heat generated by the magnesium alloy plate is transferred through multiple sets of heat-conducting rods 512. The flowing cooling water in the water-containing cavity 516 cools and absorbs heat from the lower end of the heat-conducting rods 512, thus cooling the magnesium alloy plate, reducing heat accumulation, and lowering the risk of thermal combustion of the magnesium alloy during polishing.

[0050] After polishing is completed, the polishing motor is turned off; the conveying cylinder 313 is started, and the sliding plate 35 is slid in the third slide groove to the bottom of the magnesium alloy. The telescopic column 36 is then activated to make the magnesium alloy contact the surface of the aligning seat 32; the second motor 381 is started, and the fixing block 341 is moved on the second double-threaded screw 382, ​​and the magnesium alloy is fixed and clamped by the first rollers 343 on both sides; then the first motor 49 is reversed, so that the two modules 42 move in opposite directions, at which point the magnesium alloy is released from the fixation of the two modules 42; then the connecting piece 41 is driven, which moves the two sets of modules 42, the moving frame 45 and the first driving piece 44 away from the magnesium alloy; finally, the conveying cylinder 313 is started, and the sliding plate 35 moves the polished magnesium alloy toward the door of the polishing cabinet 1 to complete the unloading.
