Description

Technical Field

[0001] This invention relates to the field of aluminum alloy strip rolling technology, and more specifically, to a high-precision aluminum alloy strip rolling forming apparatus. Background Technology

[0002] Aluminum alloys, which are aluminum-based materials with the addition of certain amounts of other alloying elements, are a type of lightweight metal. In addition to the general properties of aluminum, aluminum alloys also possess some specific alloy characteristics due to the different types and amounts of alloying elements added. They have a specific strength close to that of high-alloy steel, a specific stiffness exceeding that of steel, good casting and plastic processing properties, and good electrical and thermal conductivity, among other properties.

[0003] According to existing technology, during aluminum alloy processing, some aluminum alloys need to be rolled into aluminum alloy strips. During the rolling process, some are heated using induction heating equipment and then rolled using pressure rollers. In high-speed continuous production, the adjusting components of the rolling equipment (such as lead screws and gears) inherently have gaps or may slightly deform under stress. Because the rollers expand due to heat during rolling, the equipment cannot adjust the distance between the rollers in real time to counteract this change, ultimately leading to dynamic fluctuations in the thickness of the aluminum alloy strip. Summary of the Invention

[0004] This invention provides a high-precision aluminum alloy strip rolling forming device. It uses a hydraulic rod to drive a moving block to move the clamping rollers, and with the help of a guide structure of a limit wheel and a movable groove, it can adjust the rolling gap. Through a dual cleaning structure of a main cleaning ring (sponge pad) and a secondary cleaning ring (nylon brush), combined with a motor-driven active rotation design, it removes surface debris and oil stains, thereby solving the problem mentioned in the background art: due to the transmission gap or elastic deformation of the adjustment mechanism (such as lead screw and gear transmission) in traditional rolling equipment, the roller system expands due to heat during the rolling process and cannot compensate for the gap change in real time, resulting in dynamic fluctuations in strip thickness.

[0005] To achieve the above objectives, a high-precision aluminum alloy strip rolling forming device includes an induction device, a processing table, and a rolling device. The processing table is located on one side of the induction device. The rolling device includes a support plate fixedly connected to the side wall of the processing table. A plurality of hydraulic rods are fixedly connected to the top of the support plate. The hydraulic rods pass through the interior of the processing table. A moving block is fixedly connected to the telescopic end of the hydraulic rod. A clamping roller is rotatably connected to the surface of the moving block. A limit roller is rotatably connected inside the processing table near the clamping roller. The side wall of the processing table is equipped with a cleaning device. The cleaning device includes a connecting cylinder that is fixedly connected to the side wall of the processing table. A heat insulation cylinder is inserted inside the connecting cylinder. The heat insulation cylinder is sleeved on the coil surface of the sensing device. The connecting cylinder and the heat insulation cylinder are used to maintain the internal space temperature.

[0006] In the above technical solution, the upper and lower ends of the moving block are rotatably connected to limit wheels. The upper and lower ends of the processing table are provided with movable grooves near the limit wheels. The limit wheels pass through the movable grooves. The surface of the heat preservation cylinder is fixedly installed with bearings. Multiple connecting columns are fixedly connected to the outside of the bearings. The interior of each of the multiple connecting columns is threaded with a positioning bolt. The surface of the multiple positioning bolts is fitted with a main cleaning ring. The interior of the main cleaning ring is provided with a sponge pad. The main cleaning ring is used to absorb floating dust and light oil stains on the aluminum alloy surface.

[0007] Secondly, a secondary cleaning ring is fitted on the surface of multiple positioning bolts, and a nylon brush is provided inside the secondary cleaning ring. The secondary cleaning ring is used to physically remove debris from the surface of the aluminum alloy strip. A top rod is provided at the bottom of the insulation cylinder. The top rod is used to position and support the insulation cylinder. A limit bolt is connected to the internal thread of the top rod and the sensing device. A synchronous belt is fitted on the output end of the motor and inside the rotating ring. The motor drives the rotating ring to rotate through the synchronous belt.

[0008] Furthermore, based on the above, the surfaces of the main cleaning ring and the auxiliary cleaning ring are provided with a collection device. The collection device includes a collection box sleeved on the surfaces of the main cleaning ring and the auxiliary cleaning ring. A bracket is fixedly connected to the bottom of the collection box. A sealing block is inserted into the interior of one side of the collection box. An inclined groove is opened inside the collection box to guide impurities and debris. An installation bolt is inserted inside the bracket. The surface of the installation bolt is threaded to the inside of the support rod. A slot is opened on the surface of the insulation cylinder. The coil of the sensing device is inserted into the interior of the insulation cylinder through the slot.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: In this high-precision aluminum alloy strip rolling forming device, a hydraulic rod drives a moving block to move the clamping rollers, and with the guide structure of the limit wheel and the movable groove, the rolling gap can be adjusted. Through the dual cleaning structure of the main cleaning ring (sponge pad) and the secondary cleaning ring (nylon brush), combined with the active rotation design driven by the motor, surface debris and oil stains are removed. With the heat preservation structure of the connecting cylinder and the heat preservation cylinder, the temperature uniformity of induction heating is ensured, rolling defects are reduced, and the product qualification rate is improved. At the same time, the detachable cleaning components and the convenient collection box design reduce maintenance costs and time. Attached Figure Description

[0012] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0013] Because the adjustment mechanism (such as lead screw and gear transmission) in traditional rolling equipment has transmission gaps or elastic deformation, the roller system expands due to heat during the rolling process and cannot compensate for the changes in spacing in real time, resulting in dynamic fluctuations in strip thickness.

[0014] Therefore, in view of the above-mentioned problems, the present invention provides a high-precision aluminum alloy strip rolling forming apparatus, with reference to... Figure 1 and Figure 2As shown, the device includes a sensing device 1, a processing table 2, and a rolling device 3. The processing table 2 is located on one side of the sensing device 1. The rolling device 3 includes a support plate 32 that is fixedly connected to the side wall of the processing table 2. Multiple hydraulic rods 33 are fixedly connected to the top of the support plate 32. The hydraulic rods 33 pass through the interior of the processing table 2. With the help of the high-precision driving characteristics of the hydraulic rods 33, the rolling gap between the clamping roller 35 and the limiting roller 31 can be controlled, effectively controlling the thickness tolerance of the aluminum alloy strip within a reasonable range. A movable block 34 is fixedly connected to the telescopic end of the hydraulic rod 33. A clamping roller 35 is rotatably connected to the surface of the movable block 34. A limiting roller 31 is rotatably connected inside the processing table 2 near the clamping roller 35. Through the corresponding setting of the clamping roller 35 and the limiting roller 31, the strip is stably clamped and rolled, reducing the accuracy deviation caused by the strip movement during the rolling process. The upper and lower ends of the movable block 34 are rotatably connected to the limiting wheel 36. Movable grooves 37 are opened at the upper and lower ends of the processing table 2 near the limiting wheel 36. The limiting wheel 36 rolls inside the movable groove 37. The limiting wheel 36 and the movable groove 37 form a guiding constraint to ensure that the movable block 34 moves smoothly along a straight line under the drive of the hydraulic rod 33, avoiding the strip deviation caused by the offset of the clamping roller 35. The surface of the insulation cylinder 42 is provided with a slot. The coil of the sensing device 1 is inserted into the inside of the insulation cylinder 42 through the slot. The limiting function of the slot keeps the sensing coil in a fixed installation posture and position along the inner wall of the insulation cylinder 42, so as to avoid the coil from shifting or twisting due to equipment vibration or human installation error.

[0015] refer to Figure 3 and Figure 4 As shown, the side wall of the processing table 2 is provided with a cleaning device 4. The cleaning device 4 includes a connecting cylinder 41 fixedly connected to the side wall of the processing table 2. A heat insulation cylinder 42 is inserted inside the connecting cylinder 41. The heat insulation cylinder 42 is sleeved on the coil surface of the induction device 1. The connecting cylinder 41 and the heat insulation cylinder 42 form a heat insulation structure, which reduces the heat loss of the induction coil, maintains the uniform and stable internal temperature, ensures the uniform plasticity of the aluminum alloy strip after heating, and reduces rolling cracks and warping defects caused by local temperature differences. A bearing 43 is fixedly installed on the surface of the heat preservation cylinder 42. Multiple connecting posts 49 are fixedly connected to the outside of the bearing 43. Each of the multiple connecting posts 49 is threaded with a positioning bolt 46. The positioning bolt 46 enables the detachable connection between the main cleaning ring 44 and the secondary cleaning ring 45, which facilitates the individual replacement of the brush and the sponge pad without disassembling the entire cleaning assembly. The main cleaning ring 44 is sleeved on the surface of the multiple positioning bolts 46. The main cleaning ring 44 has a sponge pad inside. The main cleaning ring 44 performs flexible adsorption cleaning on the surface of the strip. The main cleaning ring 44 is used to adsorb floating dust and light oil stains on the aluminum alloy surface. Multiple positioning bolts 46 are fitted with secondary cleaning rings 45. The interior of the secondary cleaning rings 45 is equipped with nylon brushes. The secondary cleaning rings 45 are used to physically peel off the debris on the surface of the aluminum alloy strip. The hardness of the nylon brushes is lower than that of the aluminum alloy, effectively peeling off the oxide scale and rolling residue attached before rolling. Together with the main cleaning rings 44, they form a dual cleaning structure of peeling and adsorption.

[0016] refer to Figure 7 As shown, the bottom end of the insulation cylinder 42 is provided with a top rod 6, which is used to position and support the insulation cylinder 42. The top rod 6 and the internal thread of the sensing device 1 are connected to a limit bolt 7, forming a stable double positioning structure. The side wall of the top rod 6 is fixedly connected to a motor 48. The output end of the motor 48 and the inside of the rotating ring 47 are fitted with a synchronous belt. The motor 48 drives the rotating ring 47 to rotate through the synchronous belt. Its speed can match the strip rolling speed. Compared with the traditional passive cleaning method, the cleaning coverage is improved and the cleaning dead corners are reduced.

[0017] refer to Figure 5 - Figure 7 As shown, the surfaces of the main cleaning ring 44 and the auxiliary cleaning ring 45 are provided with a collection device 5. The collection device 5 collects the impurities and debris generated during the cleaning process in a timely manner. The collection device 5 includes a collection box 51 sleeved on the surface of the main cleaning ring 44 and the auxiliary cleaning ring 45. The semi-enclosed sleeve structure can intercept the floating dust and debris that fall off during cleaning, thereby improving the impurity collection rate. A bracket 52 is fixedly connected to the bottom of the collection box 51. The bracket 52 provides stable support for the collection box 51. A sealing block 53 is inserted into the inside of one side of the collection box 51. The sealing block 53 prevents the collected impurities from leaking out from the side, and the plug-in design makes it easy to open and clean the impurities quickly. The inside of the collection box 51 is provided with an inclined groove 54, which is used to guide the impurities and debris, so that the impurities can quickly gather to the bottom of the collection box 51 along the inclined groove 54. The inside of the bracket 52 is provided with a mounting bolt 55, and the surface of the mounting bolt 55 is connected to the inside of the support rod by threads. The threaded connection enables the collection box 51 to be detachably fixed, which facilitates the disassembly, assembly, maintenance and replacement of the collection box 51.

[0018] The working principle of this invention is as follows: The motor 48 is started, and drives the rotating ring 47 to rotate via a synchronous belt. The rotating ring 47 drives the main cleaning ring 44 and the auxiliary cleaning ring 45 to rotate synchronously, with the rotation speed matching the subsequent rolling speed. The aluminum alloy strip to be rolled first passes through the auxiliary cleaning ring 45. The nylon brush inside the auxiliary cleaning ring 45 physically peels off the surface of the strip, efficiently removing attached oxide scale debris and rolling residue. Then, the strip enters the main cleaning ring 44, where the sponge pad inside the main cleaning ring 44 flexibly adsorbs the surface of the strip, removing floating dust and light oil stains, forming a dual cleaning effect of peeling and adsorption.

[0019] Impurities generated during the cleaning process are intercepted by the main and auxiliary cleaning rings 45 and fall into the collection box 51. The impurities quickly gather to the bottom of the box along the inclined groove 54 inside the collection box 51. The sealing block 53 effectively prevents impurities from leaking out from the side, ensuring the collection of cleaning impurities and avoiding secondary adhesion of impurities that may affect rolling accuracy.

[0020] The cleaned aluminum alloy strip is conveyed to the area of ​​the sensing device 1. The coil of the sensing device 1 is positioned and installed through the slot on the surface of the insulation cylinder 42. The limiting function of the slot prevents the coil from shifting or twisting due to equipment vibration or installation error, ensuring that the induced magnetic field is evenly distributed.

[0021] The connecting cylinder 41 and the insulation cylinder 42 form an insulation structure, reducing heat loss from the induction coil, maintaining a uniform and stable temperature around the coil, ensuring consistent plasticity of the aluminum alloy strip after heating, and reducing rolling cracks and warping defects caused by local temperature differences. The push rod 6 forms a stable double positioning structure with the induction device 1 through the limiting bolt 7, providing reliable support for the insulation cylinder 42 and ensuring the stability of the heating process.

[0022] After the aluminum alloy strip has reached the required thermoplasticity, it is conveyed between the clamping roller 35 and the limiting roller 31 on the processing table 2. The hydraulic rod 33 is activated, and with its high-precision driving characteristics, it pushes the moving block 34 to move linearly along the movable groove 37 of the processing table 2. The limiting wheels 36 at the upper and lower ends of the moving block 34 and the movable groove 37 form a guiding constraint to prevent the moving block 34 from shifting and causing the clamping roller 35 to deviate.

[0023] The hydraulic rod 33 controls the rolling gap between the clamping roll 35 and the limiting roll 31, strictly controlling the thickness tolerance of the aluminum alloy strip within a reasonable range. During the rolling process, the corresponding setting of the clamping roll 35 and the limiting roll 31 achieves stable clamping of the strip, effectively reducing the accuracy deviation caused by strip movement, and finally rolling into a high-precision aluminum alloy strip.

[0024] The cleaning assembly uses positioning bolts 46 to achieve a detachable connection between the main cleaning ring 44, the secondary cleaning ring 45 and the connecting post 49. When the brush or sponge pad is worn, it can be disassembled and replaced separately without disassembling the entire cleaning assembly, thus reducing maintenance costs. The collection box 51 is fixed to the bracket 52 by mounting bolts 55. The plug-in sealing block 53 and the detachable installation method make it easy to quickly open the collection box 51 to clean internal impurities and ensure the continuous and stable operation of the device.
