Description

Technical Field

[0001] This invention relates to the field of magnesium alloy sheet rolling technology, specifically a low-cost magnesium alloy sheet rolling production line. Background Technology

[0002] The magnesium alloy sheet rolling production line is a specialized set of equipment that uses magnesium alloy ingots as raw materials and produces high-performance magnesium alloy sheets through multiple rolling processes. Magnesium alloy is a lightweight alloy formed by adding elements such as aluminum, zinc, manganese, and rare earth elements to magnesium as the matrix. Magnesium alloy also has additional properties such as vibration reduction, noise reduction, and electromagnetic shielding. The magnesium alloy sheet rolling production line is currently the lowest density metal structural material in engineering applications. This production line features lightweight, high precision, and automation. The magnesium alloy sheets produced are widely used in aerospace, automotive, 3C electronics, and other fields, and are key equipment for promoting the development of the lightweight materials industry.

[0003] However, although existing technology can achieve the production of magnesium alloy sheet rolling, it still has problems such as the separate adjustment structures above the rolling mill stand, which require turning the adjustment handles on both sides at the same time during specific adjustments, making it inconvenient and prone to jamming. Furthermore, when installing multiple rolling mill stands to form a complete production line, the lack of relative positional restrictions and linkage measures between the rolling mill stands can easily lead to unevenness and misalignment between the multiple rolling mill stands. This results in the magnesium alloy material passing through the pressure rollers unevenly during feeding, which affects the final rolling effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of the device having separate adjustment structures above the rolling mill stands, which makes it inconvenient to use and prone to jamming when adjusting, requiring simultaneous rotation of adjustment handles on both sides. Furthermore, when installing multiple rolling mill stands to form a complete production line, the lack of relative positional restrictions and linkage measures between the rolling mill stands leads to unevenness and misalignment, causing the magnesium alloy material to pass through the pressure rollers unevenly during feeding, thus affecting the final rolling effect. Therefore, this invention proposes a low-cost magnesium alloy sheet rolling production line.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Design a low-cost magnesium alloy sheet rolling production line, including a rolling mill stand and a rib placement area. The inner side of the lower part of the outer wall of the rolling mill stand is machined with ribs. The lower inner wall of the rolling mill stand is fixedly connected with a lower bearing seat. The inner wall of the lower bearing seat is rotatably connected to the lower pressure roller through a bearing. The upper inner wall of the rolling mill stand is slidably connected with an upper bearing seat. The inner wall of the upper bearing seat is rotatably connected to the upper pressure roller through a bearing. An adjustment component is installed on the upper part of the rolling mill stand. A linkage component is installed on the outer wall of the rolling mill stand.

[0007] This setting: Through the design of the upper and lower pressure rollers, the connectors on one side of the upper and lower pressure rollers can be connected to an external power source via a universal joint coupling. Specifically, during rolling, the external power source drives the upper and lower pressure rollers to rotate synchronously and in opposite directions through the universal joint coupling.

[0008] Preferably, the adjusting assembly includes worm gears, with multiple worm gears located above the rolling mill stands on both sides. The outer wall of each worm gear is meshed with a worm, and the worms are fixedly connected to each other via a rotating shaft. The inner wall of each worm gear is threaded with a threaded rod. A rotating handle is slidably connected to the inner wall of the sliding cylinder at both ends of the rotating shaft. A stop plate is fixedly connected to one end of the rotating handle, and clamping bolts are installed on the outer wall of the sliding cylinder at both ends of the rotating shaft. The ends of the clamping bolts abut against the rotating handle.

[0009] Preferably, the outer wall of the rotating part of the worm gear is rotatably connected to the support frame via a bearing, and the rear inner wall of the support frame is rotatably connected to the rotating part of the worm via a bearing.

[0010] This configuration, through the design of the rotating shaft, worm gear, worm, and threaded rod, allows the throttle to drive the worms at two locations via the rotating shaft, causing the worms to simultaneously drive the worm gear to rotate. Since the inner wall of the worm gear is threadedly connected to the threaded rod, and the threaded rod and the upper bearing seat can slide up and down on the inner wall of the rolling mill stand, the rotation of the worm gear can drive the threaded rod and the upper bearing seat to move up and down to adjust the spacing, thus achieving synchronous adjustment of the upper bearing seats on both sides.

[0011] Preferably, the lower end of the support frame is fixedly connected to the rolling mill frame via a base, and the lower end of the threaded rod is fixedly connected to the outer wall of the upper bearing seat.

[0012] Preferably, the linkage assembly includes a cylinder, and multiple cylinders are respectively fixedly connected to the upper outer wall of the rolling mill frame. A round rod is slidably connected through the inner wall of the cylinder. A conical groove is machined on the inner wall of the cylinder. Conical pressure blocks are respectively sleeved and slidably connected to both sides of the outer wall of the round rod. Nuts are attached to the inner side of the outer wall of each conical pressure block. The inner wall of the nut is threadedly connected to the round rod.

[0013] This feature, through the design of a cylinder, a conical pressure block, and a conical groove, allows the two sides of the cylindrical rod to be inserted into the inner wall of the cylinder at two different rolling mill stands. By rotating the nut, the conical pressure block is pushed to move to both sides, allowing it to move outward until it presses against the conical groove of the cylinder. Due to the conical structure design, the relative position between the two rolling mill stands can be automatically calibrated.

[0014] Preferably, the outer wall of the conical pressure block is inclined in the same direction as the inner wall of the conical groove.

[0015] Preferably, the upper inner walls of the two rolling mill stands are fixedly connected by an upper end plate.

[0016] Preferably, springs are provided on both lower sides of the upper end plate, and the upper and lower sides of the springs are fixedly connected to the upper end plate and the upper bearing seat, respectively.

[0017] This feature: The spring design makes the upper bearing housing move more smoothly during the downward reset process.

[0018] The present invention proposes a low-cost magnesium alloy sheet rolling production line, the advantages of which are:

[0019] Through the cooperation between the throttle, shaft, worm, worm wheel, threaded rod, upper bearing seat, and rolling mill stand, the throttle drives the worm at two locations via the shaft, causing the worm to simultaneously drive the worm wheel to rotate. Since the inner wall of the worm wheel is threadedly connected to the threaded rod, and the threaded rod and upper bearing seat can slide up and down on the inner wall of the rolling mill stand, the rotation of the worm wheel can drive the threaded rod and upper bearing seat to move up and down to adjust the spacing, achieving synchronous adjustment of the upper bearing seats on both sides. This effectively avoids the problem in the existing technology where separate adjustment structures are set up above the rolling mill stand, which requires rotating the adjustment handles on both sides simultaneously during specific adjustments, making it inconvenient and prone to jamming.

[0020] Through the cooperation of the conical pressure block, round rod, cylinder, nut, and rolling mill stand, the round rod with the conical pressure block is first inserted into the inner wall of the corresponding cylinder, and then the next rolling mill stand is placed. After placement, the round rod is pulled back so that the other side of the round rod is inserted into the inner wall of the cylinder at the next rolling mill stand. In this way, the two sides of the round rod are respectively located on the inner walls of the cylinder at the two rolling mill stands. Then, by rotating the nut, the conical pressure block is pushed to move to both sides, so that the conical pressure block can move outward until it is pressed against the conical groove of the cylinder. Due to the design of the conical structure, the relative position between the two rolling mill stands can be self-calibrated. In this way, the problem of unevenness between multiple rolling mill stands caused by the lack of relative position restrictions and linkage measures between the rolling mill stands can be avoided. This would result in the magnesium alloy material being unevenly pressed by multiple pressure rollers during feeding, which would affect the final rolling effect. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] See attached document Figure 1-8In this embodiment, a low-cost magnesium alloy sheet rolling production line includes a rolling mill frame 1 and placement ribs 2. Placement ribs 2 are machined on the inner side of the lower part of the outer wall of the rolling mill frame 1. The placement ribs 2 can be used to place the magnesium alloy sheet or to place it directly. The lower inner wall of the rolling mill frame 1 is fixedly connected to a lower bearing seat 10. The inner wall of the lower bearing seat 10 is rotatably connected to the lower pressure roller 9 through a bearing. The upper inner wall of the rolling mill frame 1 is slidably connected to an upper bearing seat 7. The upper bearing seat 7 can be located on the inner wall of the rolling mill frame 1. The inner wall of the upper bearing seat 7 is rotatably connected to the upper pressure roller 8 through a bearing. One side of the upper pressure roller 8 and the lower pressure roller 9 can be connected to an external power source through a universal joint coupling. Specifically, during rolling, the external power source drives the upper pressure roller 8 and the lower pressure roller 9 to rotate synchronously and in opposite directions through the universal joint coupling.

[0032] An adjustment assembly 3 is installed above the rolling mill stand 1, and a linkage assembly 4 is installed on the outer wall of the rolling mill stand 1. The upper inner walls of the two rolling mill stands 1 are fixedly connected by an upper end plate 11. Springs 12 are provided on both sides below the upper end plate 11. The elastic coefficient of the springs 12 can be determined according to the specific application. The upper and lower sides of the springs 12 are fixedly connected to the upper end plate 11 and the upper bearing seat 7, respectively.

[0033] See attached document Figure 1-8 In this embodiment, the adjusting component 3 includes worm gears 301. Multiple worm gears 301 are located above the rolling mill stands 1 on both sides. The worm gears and worms adopt a self-locking structure design. Worms 304 are meshed and connected to the rear side of the outer wall of the worm gear 301. The worms 304 are fixedly connected to each other via a rotating shaft 306. A threaded rod 302 is threadedly connected to the inner wall of the worm gear 301. A handle 303 is slidably connected to the inner wall of the sliding cylinder at both ends of the rotating shaft 306. A stop plate 307 is fixedly connected to one end of the handle 303. The two sides of the rotating shaft 306... A clamping bolt 305 is installed on the outer wall of the end slide. The clamping bolt 305 can limit the specific position of the throttle 303 at the end of the slide of the rotating shaft 306. The end of the clamping bolt 305 abuts against the throttle 303. The outer wall of the rotating part of the worm gear 301 is rotatably connected to the support frame 6 through a bearing. The inner rear wall of the support frame 6 is rotatably connected to the rotating part of the worm 304 through a bearing. The lower end of the support frame 6 is fixedly connected to the rolling mill frame 1 through the base 5. The lower end of the threaded rod 302 is fixedly connected to the outer wall of the upper bearing seat 7.

[0034] See attached document Figure 1-8In this embodiment, the linkage component 4 includes a cylinder 403. Multiple cylinders 403 are fixedly connected to the upper outer wall of the rolling mill frame 1. A round rod 402 is slidably connected through the inner wall of the cylinder 403. A conical groove 404 is machined on the inner wall of the cylinder 403. Conical pressure blocks 401 are respectively sleeved and slidably connected on both sides of the outer wall of the round rod 402. The conical pressure blocks 401 can move laterally on the outer wall of the round rod 402. Nuts 405 are attached to the inner side of the outer wall of the conical pressure blocks 401. The nuts 405 can rotate and move on the round rod 402, so that the nuts 405 can push the conical pressure blocks 401 to move. The inner wall of the nuts 405 is threadedly connected to the round rod 402. The inclination direction of the outer wall of the conical pressure blocks 401 is the same as the inclination direction of the inner wall of the conical groove 404.

[0035] Working principle:

[0036] When this low-cost magnesium alloy sheet rolling production line is needed, the user can install one of the rolling mill stands 1 in the corresponding production line installation position. Then, the connector on one side of the upper pressure roller 8 and the lower pressure roller 9 is connected to an external power source through a universal joint coupling. During rolling, the external power source drives the upper pressure roller 8 and the lower pressure roller 9 to rotate synchronously and in opposite directions through the universal joint coupling. The magnesium alloy material can then pass through the gap between the upper pressure roller 8 and the lower pressure roller 9 to achieve rolling.

[0037] When adjusting the thickness of the rolled product, the user needs to adjust the height of the upper pressure roller 8 to control the gap between the upper pressure roller 8 and the lower pressure roller 9. In practice, the handle 303 is rotated, causing it to drive the worm gears 304 at both locations via the shaft 306. The worm gears 304 simultaneously drive the worm wheel 301 to rotate. Since the inner wall of the worm wheel 301 is threadedly connected to the threaded rod 302, and the threaded rod 302 and the upper bearing seat 7 can slide up and down on the inner wall of the rolling mill stand 1, the rotation of the worm wheel 301 drives the threaded rod 302 and the upper bearing seat 7 to rotate. The downward adjustment distance enables synchronous adjustment of the upper bearing seats 7 on both sides. This effectively avoids the problem in the prior art where separate adjustment structures are set up above the rolling mill stand, which requires simultaneous rotation of the adjustment handles on both sides, making it inconvenient and prone to jamming. In addition, during operation, the user can loosen the clamping bolt 305 to allow the handle 303 to slide freely inside the slide at the end of the shaft 306, and then tighten the bolt 305 after the side of the handle 303 with the larger end is extended. This makes it easier to rotate the shaft 306 by holding the handle 303.

[0038] When installing multiple rolling mill stands 1 to form a complete production line, the lack of relative positional constraints and linkage between the stands can easily lead to unevenness and misalignment. This results in the magnesium alloy material passing through the pressure rollers multiple times during feeding, affecting the final rolling effect. Therefore, this design incorporates a linkage component 4. After installing one rolling mill stand 1, a round rod 402 with a conical pressure block 401 is inserted into the inner wall of the corresponding cylinder 403. Then, the next rolling mill stand 1 is placed. After placement, the round rod 402 is pulled back, allowing its other side to insert into the cylinder 403 at the next rolling mill stand 1. The two sides of the round rod 402 are respectively located on the inner walls of the cylinder 403 at two rolling mill stands 1. Then, by rotating the nut 405, the conical pressure block 401 is pushed to move to both sides, so that the conical pressure block 401 can move outward until it is pressed against the conical groove 404 of the cylinder 403. Due to the design of the conical structure, the relative position between the two rolling mill stands 1 can be self-calibrated. In this way, the problem that the lack of relative position restrictions and linkage measures between the rolling mill stands can easily lead to unevenness between multiple rolling mill stands, which will cause the magnesium alloy material to be unevenly pressed by multiple pressure rollers when it is fed in, thus affecting the final rolling effect.

[0039] Finally, the rolling mill stand 1 is installed on the production line one by one in the above manner, and a complete rolling production line is finally formed. Since the improved structure involved in this case is only a basic mechanical part, namely a nut, a round rod, a worm gear and other commonly used mechanical parts, the overall improvement will not significantly increase the operating cost of the equipment.

[0040] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will understand that various changes in form and detail are possible within the scope of the claims.
