Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, specifically a high-precision rolling mill for processing aluminum alloy ingots. Background Technology

[0002] The reference patent title is: A Novel Aluminum Alloy Rolling Mill (Authorization Announcement No.: CN217700678U, Authorization Announcement Date: 2022.11.01), which includes a support frame, a fixed rolling assembly, a primary rolling assembly, a secondary rolling assembly, and a guide assembly. A support frame is connected to each end of the fixed rolling assembly, and a primary rolling assembly is located on one side of the fixed rolling assembly. In actual aluminum alloy processing, when aluminum alloy needs to be rolled, the aluminum alloy plate can be placed above the primary rolling gap, and rolled through the primary rolling gap between the fixed rolling assembly and the primary rolling assembly. Subsequently, the aluminum alloy plate passes through the primary rolling gap and contacts the guide plate, and enters the secondary rolling gap under the guidance of the guide plate. The aluminum alloy plate is then subjected to secondary rolling through the cooperation of the fixed rolling assembly and the secondary rolling assembly. Simultaneously, the position of the guide plate can be adjusted by adjusting the assembly to better guide the aluminum alloy plate, thereby better guiding the primary rolled aluminum alloy plate, facilitating better secondary rolling of the aluminum alloy by the rolling mill, and eliminating safety hazards.

[0003] Based on the above-mentioned documents, ensuring stable feeding and precise positioning of aluminum alloy ingots during the rolling process is crucial for improving rolling quality. In existing rolling mills, aluminum alloy ingots are prone to rolling deviations due to positional shifts during the feeding stage, resulting in uneven thickness and edge burrs. Furthermore, the adjustment accuracy and stability of the roll gap significantly impact product quality. Traditional adjustment mechanisms suffer from slow response speeds and poor synchronization, making it difficult to meet the demands of high-precision rolling. In addition, some rolling mills lack effective positioning and guiding structures, causing aluminum alloy ingots to easily become skewed before entering the rolls, affecting product accuracy and potentially causing equipment jamming and reduced production efficiency. Therefore, this utility model provides a high-precision rolling mill for aluminum alloy ingot processing. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A high-precision rolling mill for processing aluminum alloy ingots includes a base 1, with a symmetrical support plate 2 fixedly connected to the top of the base 1. An upper roll 4 slides on the top of the support plate 2 via an adjusting assembly 3. A rotary motor 5 is fixedly connected to the outer side of the support plate 2. One end of the output shaft of the rotary motor 5 is fixedly connected to a lower roll 6 via a coupling. A top plate 7 is mounted on the top of the support plate 2. A positioning mechanism 8 is provided on one side of the support plate 2, and the positioning mechanism 8 includes:

[0025] The positioning assembly 81 includes a bearing plate 811 installed on one side of the support plate 2. A symmetrical bearing rod 812 is fixedly connected to the inner wall of the bearing plate 811. A sliding plate 813 is slidably connected to the surface of the bearing rod 812. A sliding rod 814 is fixedly connected to one side of the sliding plate 813. A sliding block 815 is fixedly connected to one end of the sliding rod 814. A positioning plate 816 is fixedly connected to the top of the sliding plate 813 through a fixing block. Multiple sets of positioning shafts 817 are rotatably connected to the inner side of the positioning plate 816.

[0026] The drive component 82 is located at the bottom of the support plate 811 and is used to drive the positioning plate 816 to achieve sliding operation.

[0027] Both sets of support plates 2 have sliding slots for the adjustment plate 35, and a limit rod is installed at the bottom of the slot cavity. The limit rod is used to limit the sliding of the adjustment plate 35.

[0028] The rotating motor 5 is a three-phase asynchronous motor and is connected to an external circuit via wires;

[0029] The lower roller 6 is rotatably mounted on the inner side of the two support plates 2;

[0030] The bearing rod 812 is used to limit the sliding of the sliding plate 813.

[0031] In this embodiment, a symmetrical limiting groove 9 is provided on the top of the bearing plate 811, and the inner surface of the limiting groove 9 is slidably connected to the surface of the fixing block.

[0032] In this embodiment, the drive assembly 82 includes an electric telescopic rod 821 installed at the bottom of the support plate 811. The output end of the electric telescopic rod 821 is fixedly connected to a drive rod 822. The surface of the drive rod 822 is slidably connected to the bottom of the support plate 811. The top end of the drive rod 822 is fixedly connected to a drive plate 823. The top of the drive plate 823 is provided with a symmetrical inclined groove 824. The inner surface of the inclined groove 824 is slidably connected to the surface of the sliding block 815.

[0033] The sliding fit between the limiting groove 9 and the fixed block, and between the limiting slide rail 10 and the drive plate 823, ensures the stability of the movement of the positioning plate 816 and the drive plate 823, and reduces the impact of mechanical vibration on positioning accuracy.

[0034] The bottom of the support plate 811 is provided with a groove for the drive rod 822 to slide.

[0035] With the positioning mechanism 8 in place, the positioning plate 816 is slid by the drive component 82. The spacing between the two sets of positioning plates 816 can be adjusted according to the width of the aluminum alloy ingot. The positioning shaft 817 rolls in contact with the surface of the aluminum alloy ingot, which can not only avoid scratching the surface, but also limit its lateral displacement, ensuring that the aluminum alloy ingot fed into the roll is accurately positioned and improving the dimensional consistency after rolling.

[0036] In this embodiment, a symmetrical limiting slide rail 10 is fixedly connected to the bottom of the inner cavity of the bearing plate 811, and the surface of the limiting slide rail 10 is slidably connected to the bottom of the drive plate 823.

[0037] In this embodiment, the adjustment assembly 3 includes an adjustment motor 31 installed on the top of the support plate 2. One end of the output shaft of the adjustment motor 31 is fixedly connected to an adjustment rod 32 via a coupling. The surface of the adjustment rod 32 is rotatably connected to the top of the support plate 2. Two sets of worm gears 33 are fixedly connected to the surface of the adjustment rod 32. The surface of the worm gears 33 is connected to the transmission assembly 34, which causes the adjustment plate 35 to slide on the inner surface of the support plate 2. A control motor 36 is fixedly connected to one side of the adjustment plate 35. One end of the output shaft of the control motor 36 is fixedly connected to the inside of the upper roller 4 via a coupling.

[0038] Both the regulating motor 31 and the control motor 36 are three-phase asynchronous motors and are connected to an external circuit via wires.

[0039] Two sets of support blocks are installed on the top of the support plate 2, and the adjusting rod 32 rotates inside the support blocks;

[0040] The adjusting rod 32 rotates inside the protective box 341.

[0041] In this embodiment, the transmission assembly 34 includes a protective box 341 mounted on the top of the support plate 2. A worm gear 342 is rotatably connected inside the protective box 341. The surface of the worm gear 342 meshes with the surface of the worm 33. A transmission screw 343 is fixedly connected to the bottom of the worm gear 342. The surface of the transmission screw 343 is rotatably connected to the inside of the support plate 2. The surface of the transmission screw 343 is threadedly connected to the inside of the adjusting plate 35.

[0042] The two sets of support plates 2 are equipped with transmission screws 343 and adjusting plates 35 of the same specifications inside;

[0043] A control panel is installed on the top of the base 1. The control panel is electrically connected to the adjusting motor 31, the control motor 36, the electric telescopic rod 821 and the rotating motor 5 in the device.

[0044] With the adjustment component 3, a transmission structure consisting of worm gear 33, worm wheel 342, and transmission screw 343 is adopted. When the adjustment motor 31 drives the adjustment rod 32 to rotate, the two sets of worm gears 33 synchronously drive the worm wheel 342 and transmission screw 343 to rotate, so that the adjustment plate 35 drives the upper roll 4 to rise and fall smoothly. The transmission accuracy is high and the self-locking is good. It can accurately control the rolling gap and adapt to the processing requirements of different thicknesses.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] During operation, based on the width of the aluminum alloy ingot, the electric telescopic rod 821 is activated via the control panel, driving the drive plate 823 to slide along the limiting slide rail 10. This causes the inclined slide groove 824 to push the sliding blocks 815 on both sides to move synchronously to the opposite side, making the sliding plate 813 slide along the bearing rod 812. The sliding plate 813 then drives the fixed block to slide on the inner surface of the limiting groove 9, causing the positioning plate 816 to slide synchronously. Ultimately, this achieves the adjustment of the spacing between the two positioning plates 816 and the multiple sets of positioning shafts 817, facilitating the centering of aluminum alloy ingots of different widths, thereby improving the subsequent rolling accuracy and quality of the aluminum alloy ingot. The control panel starts the adjusting motor 31, which drives the worm gear 33, worm wheel 342 and transmission screw 343 to rotate. The rotation of the transmission screw 343 can adjust the height of the adjusting plate 35, so that the adjusting plate 35 slides on the surface of the limit rod and the inner surface of the groove opened on the surface of the support plate 2, thereby adjusting the height of the upper roll 4 and setting the rolling gap between the upper roll 4 and the lower roll 6. Finally, guided by the positioning shaft 817, the aluminum alloy ingot enters the rolling area. The control panel drives the rotating motor 5 and the control motor 36 synchronously and in opposite directions, and the aluminum alloy ingot is rolled by the upper roll 4 and the lower roll 6.
