Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, specifically to a high-efficiency and energy-saving rolling equipment for aluminum profiles. Background Technology

[0002] Rolled aluminum profile rolling equipment uses rolling processes to press aluminum sheets into thinner plates, making it a key piece of equipment for deep processing of aluminum materials. The aluminum sheets thinned by rolling have uniform thickness, a smooth and flat surface, optimized mechanical properties, and significant lightweight advantages.

[0003] Citing Chinese Patent Publication No. 202411066507.7, an aluminum alloy coil rolling device and rolling method are disclosed. The initially formed material is fed into the interior of the rolling assembly for rolling. The aluminum alloy coil achieves primary cooling and adsorbs dust on the surface of the coil through the circulating air intake of the inclined material table. The dust removal conveying assembly can realize stable conveying of the aluminum alloy coil and perform secondary cooling and dust removal. The coil enters the support table from the discharge end of the dust removal conveying assembly. The self-dispersing cold roller achieves uniform temperature at both ends by changing the water inlet channel.

[0004] Before aluminum sheets undergo rolling, some impurities may adhere to their surface. During rolling, these impurities are pressed into the aluminum sheet by the rolling equipment, resulting in depressions on the surface of the rolled sheet and affecting the quality of the resulting profile.

[0010] Preferably, a second cam is provided at the top of the feeding platform, located at the top of the first cam, and brush strips are fixedly connected to the outer wall of the second cam and the outer wall of the first cam.

[0011] Preferably, the top of the calender is fixedly connected to two limiting frames, and each limiting frame is movably connected to a spacer plate. The spacer plate is movably connected to the two ends corresponding to the second cam. A second motor is fixedly connected to the outer wall of one of the spacer plates, and the output shaft of the second motor is fixedly connected to the second cam.

[0012] Preferably, a spacer threaded rod is movably connected to the top of the spacer plate, and the spacer threaded rod is movably connected to the corresponding limiting frame via threads. The top of the spacer threaded rod is provided with a rotatable interface.

[0013] Preferably, a first clamping roller is provided inside the feeding platform on the right side of the first cam, and a second clamping roller is provided on the top of the first clamping roller. The two ends of the second clamping roller are respectively movably connected to movable ends, and the movable ends are respectively movably connected to the top of the feeding platform. A first spring is fixedly connected to the top of the movable end, and the top of the first spring is fixedly connected to the feeding platform.

[0014] Preferably, the discharge mechanism includes a discharge platform, which is fixedly connected to the right side of the calender. An air support box is fixedly connected inside the discharge platform, a blower is fixedly connected to the bottom of the air support box, and multiple exhaust holes are provided on the top of the air support box.

[0015] Preferably, a drive roller is provided on the top of the discharge platform, and support plates are provided at both ends of the drive roller. The support plates are fixedly connected to the top of the discharge platform. The drive roller is located at the top right of the air support box. A third motor is fixedly connected to the outer wall of one of the support plates, and the output shaft of the third motor is fixedly connected to the drive roller.

[0016] Preferably, the outer wall of the drive roller is provided with a striking roller, and both ends of the striking roller are movably connected to a connecting end. The outer wall of each connecting end is fixedly connected to a second spring, and the second spring is fixedly connected to the outer wall of the drive roller.

[0017] This invention provides a high-efficiency and energy-saving rolling mill for aluminum profiles. It offers the following advantages:

[0018] 1. This high-efficiency and energy-saving aluminum profile rolling equipment uses a first cam and a second cam to drive the metal plate to rotate, causing the metal plate to vibrate. This loosens the substances attached to the surface of the metal plate, and the driven brush strip removes the impurities from the surface of the metal plate, keeping the surface of the aluminum metal plate clean and avoiding pit defects caused by impurities, thereby improving the quality of the rolled product.

[0019] 2. This high-efficiency and energy-saving aluminum profile rolling equipment uses the first and second cams to slightly bend and fold the aluminum sheet, making it more relaxed. At the same time, the raised parts push the surface of the sheet, making the raised parts of the aluminum sheet more flat, resulting in a more uniform distribution of rolling force, smaller thickness tolerance, and higher consistency, thus improving the quality of the rolled product.

[0020] 3. This high-efficiency and energy-saving aluminum profile rolling equipment uses a blower to send outside air into the air support box. The airflow through the exhaust holes lifts the formed aluminum sheet, preventing the aluminum sheet from directly contacting the support structure and deforming. The airflow accelerates the cooling of the aluminum sheet, which increases the hardness of the formed aluminum sheet and prevents its surface from deforming under contact, thereby improving the quality of the rolled product.

[0021] 4. This high-efficiency and energy-saving aluminum profile rolling equipment uses drive rollers to roll over the surface of aluminum sheets, creating a downward pushing effect on the sheets. During this process, it can generate a slight impact on the aluminum sheets to release the internal stress accumulated in the aluminum during rolling. At the same time, the knocking vibration combined with the airflow flexible support evenly smooths out slight waves, warps, and local protrusions after rolling, thereby improving the quality of the rolled products.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0033] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a high-efficiency and energy-saving rolling aluminum profile rolling equipment, including a rolling mill 1, a rolling roll 3 is provided inside the rolling mill 1, a drive mechanism 2 is fixedly connected to the front of the rolling mill 1, an adjustment mechanism 4 is provided on the top of the rolling mill 1, the rolling parameters of the drive mechanism 2 can be adjusted by the adjustment mechanism 4, a feeding mechanism 5 is fixedly connected to the outer wall of the rolling mill 1 on the left side of the drive mechanism 2, and a discharging mechanism 6 is fixedly connected to the outer wall of the rolling mill 1 on the right side of the drive mechanism 2;

[0034] Feeding mechanism 5 includes:

[0035] Feeding platform 51 is fixedly connected to the left side of calender 1, and two supporting shaft rollers are installed inside the feeding platform 51;

[0036] The first cam 52 is movably connected inside the feed table 51 and is located between two rollers. The outer wall of the feed table 51 is fixedly connected to the first motor 59, and the output shaft of the first motor 59 is fixedly connected to the first cam 52.

[0037] The raw aluminum sheet is placed on the top of the feeding table 51 and pushed towards the rolling roller 3. One end of the aluminum sheet is placed between the two corresponding rolling rollers 3. Then, the rolling roller 3 is driven to rotate by the driving mechanism 2 to roll the aluminum sheet. The rolled aluminum sheet is then conveyed to the right and sent out through the discharge mechanism 6.

[0038] A second cam 54 is provided on the top of the feeding platform 51, which is located on the top of the first cam 52. Brush strips 53 are fixedly connected to the outer wall of the second cam 54 and the outer wall of the first cam 52.

[0039] Two limiting frames 55 are fixedly connected to the top of the calender 1, and a spacer plate 56 is movably connected inside each limiting frame 55. The spacer plate 56 is movably connected to the two ends of the second cam 54 respectively. A second motor 58 is fixedly connected to the outer wall of one of the spacer plates 56, and the output shaft of the second motor 58 is fixedly connected to the second cam 54.

[0040] As the aluminum sheet is gradually fed to the right onto the rolling roller 3, the first motor 59 and the second motor 58 drive the corresponding first cam 52 and second cam 54 to rotate, respectively. During this process, the protruding part of the first cam 52 will push the metal sheet upward under the action of rotation, causing the metal sheet to vibrate upward and bend slightly upward. Subsequently, the protruding part of the second cam 54 will push the metal sheet downward under the action of rotation, causing the metal sheet to vibrate downward and bend slightly downward. The metal sheet will vibrate up and down, loosening the material attached to the surface of the metal sheet. With the rotation of the first cam 52 and the second cam 54, the brush strip 53 will brush away the impurities on the surface of the metal sheet and sweep them to the left, keeping the surface of the aluminum sheet clean and preventing impurities from causing pit defects on the surface of the rolled metal under pressure during rolling.

[0041] Furthermore, when the aluminum metal is lifted by the protruding parts of the first cam 52 and the second cam 54, the aluminum metal plate will be slightly bent and folded from top to bottom, making the aluminum metal plate more relaxed. As the corresponding protruding parts of the second cam 54 and the first cam 52 push the surface of the metal plate, the protruding parts of the aluminum metal plate will be made more flat. After being slightly bent, the aluminum plate enters the roller with a flexible arc surface, which can evenly adhere to the upper and lower roller surfaces, resulting in a more uniform distribution of rolling force, smaller thickness tolerance of the whole plate, and higher consistency.

[0042] A spacer threaded rod 57 is movably connected to the top of the spacer plate 56. The spacer threaded rod 57 is movably connected to the corresponding limiting frame 55 via threads. The top of the spacer threaded rod 57 is provided with a rotatable interface.

[0043] The distance between the second cam 54 and the first cam 52 can be adjusted by turning the knob on the top of the distance threaded rod 57, so as to accommodate aluminum metal plates of different thicknesses.

[0044] Inside the feeding platform 51, a first clamping roller 510 is provided on the right side of the first cam 52. A second clamping roller 511 is provided on the top of the first clamping roller 510. Movable ends 512 are movably connected to both ends of the second clamping roller 511. The movable ends 512 are movably connected to the top of the feeding platform 51. A first spring 513 is fixedly connected to the top of the movable end 512. The top of the first spring 513 is fixedly connected to the feeding platform 51.

[0045] Before the aluminum sheet is fed into the rolling roll 3, it passes between the second clamping roll 511 and the first clamping roll 510. Under the push of the first spring 513, the second clamping roll 511 clamps the aluminum sheet with the first clamping roll 510. When the aluminum sheet is shaken, it fixes the aluminum sheet and prevents the aluminum sheet from bending during rolling, which would affect the rolling of the aluminum sheet.

[0046] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0047] The discharge mechanism 6 includes a discharge platform 61, which is fixedly connected to the right side of the calender 1. An air support box 62 is fixedly connected inside the discharge platform 61. A blower 63 is fixedly connected to the bottom of the air support box 62. Multiple exhaust holes are provided on the top of the air support box 62.

[0048] Blower 63 continuously delivers outside air into air support box 62. As the amount of gas inside air support box 62 increases, the exhaust port at the top of air support box 62 continuously discharges air. The rolled aluminum sheet moves to the right under the support of the airflow and is cooled by the airflow. The surface of the aluminum sheet softens due to heat caused by compression after rolling. The airflow lifts the aluminum sheet to prevent it from directly contacting the supporting structure and deforming. The airflow accelerates the cooling of the aluminum sheet, which can increase the hardness of the formed aluminum sheet and thus prevent its surface from deforming under the action of contact.

[0049] A drive roller 66 is provided on the top of the discharge platform 61. Support plates 64 are provided at both ends of the drive roller 66, and the support plates 64 are fixedly connected to the top of the discharge platform 61. The drive roller 66 is located at the top right of the air support box 62. A third motor 65 is fixedly connected to the outer wall of one of the support plates 64, and the output shaft of the third motor 65 is fixedly connected to the drive roller 66.

[0050] A striking roller 67 is provided on the outer wall of the drive roller 66. Both ends of the striking roller 67 are movably connected to a connecting end 69. A second spring 68 is fixedly connected to the outer wall of the connecting end 69. The second spring 68 is fixedly connected to the outer wall of the drive roller 66.

[0051] The third motor 65 drives the drive roller 66 to rotate counterclockwise. The striking roller 67 moves to the surface of the aluminum sheet under the drive roller 66 and pushes the aluminum sheet downward. The second spring 68 passively bends when the striking roller 67 contacts the aluminum sheet to reduce the direct contact force. During this process, the striking roller 67 will produce a slight impact on the aluminum sheet to release the internal stress accumulated in the aluminum during the rolling process. Then, because the bottom of the aluminum sheet is supported by airflow, the striking roller 67 will be pushed by the second spring 68 to make the surface of the aluminum sheet slightly bend. The striking vibration combined with the flexible support of airflow evenly smooths out the slight waves, warps, and local bulges after rolling.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
