Description

Technical Field

[0001] This invention relates to the field of aluminum alloy rolling technology, specifically to a special mechanical device for continuous aluminum alloy rolling. Background Technology

[0002] Continuous casting and rolling is a crucial process for producing aluminum alloy sheets, strips, and wires. This process combines continuous casting and rolling deformation into a single operation. The rolls function as both liquid metal crystallizers and rolling presses, eliminating the demolding and cooling steps found in traditional processes, thus achieving integrated casting and rolling production. Compared to the traditional multi-step process of "ingot casting—sawing—heating—hot rolling," continuous casting and rolling significantly saves energy, reduces labor hours, lowers equipment investment, and increases product yield from approximately 70% to 90%. With its advantages of simple equipment, low investment, rapid construction, and convenient maintenance, continuous casting and rolling of aluminum alloys has received widespread attention and continuous improvement since its industrial application. Currently, continuous rolling equipment for aluminum alloys mainly includes twin-roll casting mills, multi-stand continuous rolling mills, and supporting coiling systems. Taking twin-roll casting as an example, molten aluminum is injected between two relatively rotating cooling rolls through a flow channel and a distribution system. Under the cooling effect of the rolls, it solidifies rapidly and undergoes plastic deformation under the pressure applied by the rolls, forming an aluminum sheet / strip blank with a certain thickness. It is then thinned to the target thickness through subsequent finishing mill stands.

[0003] CN115555406A discloses an integrated production equipment for continuous rolling of aluminum alloy profiles. By adjusting the positions of two arc-shaped clamping plates, the arc-shaped limiting plates can limit the position of the workpiece on both sides under the elastic action of the limiting springs, so that the workpiece will not be offset during the conveying process of the roller conveyor belt, making the rolling work more convenient. The height of the rolling roll can be adjusted by rotating the first adjustment knob, and the height of the rolling roll can be adjusted according to the specifications and dimensions of the rolled profile and the processing requirements. Summary of the Invention

[0004] To address the problem of heat accumulation affecting equipment caused by continuous hot rolling in existing technologies, the present invention provides the following technical solution: a special mechanical device for continuous rolling of aluminum alloys, comprising: a fixed frame, wherein the fixed frame is configured as a frame structure.

[0005] A circulating water tank is fixedly connected to the inner wall side of the fixed frame, a support frame is fixedly connected to the top side of the circulating water tank, and a rolling device is fixedly connected to the side of the circulating water tank. The rolling device includes a support bracket, on the side of which a fixed end of a motor is fixedly connected, and on the drive shaft of the motor are fixedly connected agitator blades.

[0006] A rolling wheel is rotatably connected to the side of the support bracket, and a water supply pipe is connected through and fixedly to the top of the support bracket. The motor is located inside the circulating water tank, and the side of the support bracket is fixedly connected to the side of the circulating water tank.

[0007] The fixed frame provides overall support for the equipment, the circulating water tank stores and circulates cooling water for cooling, the support frame supports and guides the aluminum material, and the rolling device rolls the workpiece step by step.

[0008] Start the motor, and the motor's drive shaft will drive the agitator blades to rotate. The rotation of the agitator blades will cause water to flow into the water delivery pipe.

[0009] The rolling mill is rotated by agitating blades, and the support bracket supports the rolling mill and water supply pipe. The profile is continuously rolled by extruding it with multiple sets of rolling mills, and the high temperature during the rolling process is reduced by the intervention of cooling water.

[0010] To avoid the impact of high temperatures caused by prolonged continuous rolling on the equipment, the material is rolled instantaneously during the melting process, thereby stabilizing the quality of the aluminum. The aluminum is then hardened by water cooling, which further stabilizes the quality of the aluminum, shortens the rolling cycle, and improves production efficiency.

[0011] Preferably, the agitating blade includes a drive gear, and the input end of a belt drive assembly is fixedly connected to the side of the drive gear.

[0012] A drainage blade is fixedly connected to the side of the drive gear away from the belt drive assembly.

[0013] The side of the drive gear is fixedly connected to the drive shaft of the motor, the drainage blade is located inside the circulating water tank, and the side of the drive gear is rotatably connected to the side of the support bracket.

[0014] Preferably, the rolling wheel includes a rolling shell, and a circulation cavity is formed on the side of the rolling shell.

[0015] A guide ring is fitted and fixedly connected to the side of the rolled shell, and heat dissipation holes are provided on the side of the guide ring.

[0016] A driven gear is fixedly connected to the side of the rolled shell, and the side of the driven gear meshes with the side of the driving gear.

[0017] The side of the driven gear is rotatably connected to the side of the support bracket. When the motor is started, the drive shaft of the motor rotates, causing the driving gear to rotate.

[0018] The rotation of the drive gear drives the drainage blades to rotate, which in turn causes the water to flow along the inside of the circulating water tank. The rotation of the drive gear also drives the belt drive assembly to rotate.

[0019] The belt drive assembly rotates, causing the water supply pipe to rotate, which facilitates the circulation of water. The drive gear rotates, causing the driven gear to rotate. When the driven gear rotates...

[0020] Water is introduced into the interior of the rolling shell through the water supply pipe. The water flows inside the circulation cavity, and the guide ring restricts the movement trajectory of the aluminum material.

[0021] The aluminum material moves under the guidance of the guide ring, and the heat dissipation holes facilitate heat dissipation, allowing water to circulate inside the rolled shell.

[0022] The surface of the rolled shell is cooled down. Rolling and cooling are carried out at the moment of contact with high-temperature aluminum material, so that the profile is cooled and shaped at the same time as rolling, avoiding the impact of the heat of aluminum material on the equipment during traditional multi-layer continuous rolling.

[0023] Preferably, the water supply pipe includes a water conveying pipe, and the bottom of the water conveying pipe is connected to the outlet of a water pump.

[0024] The side of the water supply pipe is connected to a drain pipe, and the top of the water supply pipe is connected to a water inlet pipe. The water pump is located inside the circulating water tank.

[0025] The water supply pipe passes through the side of the support bracket and is fixedly connected to the support bracket.

[0026] Preferably, the water supply pipe includes a delivery inner pipe, and a water inlet hole is provided on the side of the delivery inner pipe.

[0027] The top of the inner conveying pipe is connected to an inlet pipe, and a return pipe is sleeved and fixedly connected to the side of the inner conveying pipe.

[0028] A limiting ring is fitted and fixedly connected to the side of the return water pipe. A return water hole is opened on one side of the limiting ring. The return water pipe is fixedly connected to the side of the support bracket. The top of the inlet water pipe is connected to the top of the delivery water pipe.

[0029] The return water pipe is located inside the circulation cavity. The rotation of the drive gear drives the drainage blades to rotate, and the rotation of the drainage blades drives the water flow along the inside of the circulation pool. The rotation of the drive gear drives the belt drive assembly to rotate, and the rotation of the belt drive assembly drives the water pump to rotate.

[0030] The water pump draws water from inside the circulating water tank. The water flows along the water delivery pipe into the inside of the drain pipe and the water supply pipe. The water flows along the inlet pipe into the inside of the inner conveying pipe and then into the inside of the rolling shell through the inlet hole.

[0031] After the water passes through the heat exchanger, it enters the gap between the inner conveying pipe and the return water pipe through the return water hole and flows back into the interior of the circulating water tank along the side of the support bracket. The setting of the limit ring restricts the return water pipe from entering the interior of the rolling shell.

[0032] The rolling shell is heat-exchanged by continuously dissipating heat inside the rolling shell through the inner conveying pipe and the return water pipe, thereby ensuring continuous heat dissipation of the aluminum material, and the rolling shell is rotated by a drive gear.

[0033] During the rolling process, the aluminum material is rolled by the rotation of the rolling shell. The water flow is guided by the linkage between the drive gear and the rolling shell during the rolling process, so as to facilitate automatic heat dissipation during the rolling process and realize different water supply speeds according to the rolling speed.

[0034] Preferably, the circulating water tank includes a water storage tank, and a partition plate is fixedly connected to the inner wall side of the water storage tank, and circulation holes are opened on the side of the partition plate.

[0035] The top of the water storage tank is connected to a backflow baffle, the side of the support bracket is fixedly connected to the side of the backflow baffle, and the drive gear is set on the side of the partition plate and rotatably connected to the side of the partition plate.

[0036] The support frame is located on one side of the circulation hole, and the water pump is located on the side of the partition plate, away from the drive gear.

[0037] Preferably, the support frame includes a support base, a support plate is fixedly connected to the top of the support base, a guide groove is provided on the top of the support plate, and the bottom of the support base is fixedly connected to the top of the water storage tank.

[0038] The water storage tank stores the water flow at the bottom, and the partition plate divides the water flow. The hot water that circulates back enters the interior of the return baffle through the side of the support bracket and then enters the interior of the water storage tank.

[0039] The water flows along the partition plate to the water storage tank located below the support base, and is agitated and cooled by the belt drive assembly. The support plate on the top of the support base continuously supports the aluminum material, and guides and supports the aluminum material through the guide groove, so as to facilitate the guiding and positioning of the aluminum material during the rolling movement on the top of the guide groove.

[0040] To prevent the aluminum material from coming off the roll and to ensure full contact between the aluminum material and the rolling shell, the aluminum material is cooled and shaped during the rolling process.

[0041] The beneficial effects of the technical solution provided by this invention include: 1. A fixed frame supports the entire equipment. Cooling water is stored in a circulating water tank, and the circulating water provides cooling. The support frame holds the aluminum material and guides its movement, while the rolling device rolls the workpiece in stages. After the motor starts, water is fed into the water supply pipe, and the rolling rollers rotate accordingly. The support frame supports the rolling rollers and the water supply pipe. Multiple sets of rolling rollers continuously extrude the profile to complete the rolling process. The introduction of cooling water reduces the high temperature during profile rolling, preventing overheating of the equipment due to prolonged continuous rolling. Instantaneous rolling during the material melting process stabilizes the quality of the aluminum. Subsequent water cooling hardens the aluminum, further stabilizing its quality and shortening the rolling cycle.

[0042] 2. After the motor starts, the water in the circulating water tank begins to flow, and the rotation of the water supply pipe promotes water circulation. The water is guided into the interior of the rolling shell and flows in the circulating cavity. Guide rings restrict the movement trajectory of the aluminum material, which moves along the guide rings. Heat dissipation holes help dissipate heat, and the water circulates inside the rolling shell. The surface of the rolling shell is cooled, and the rolling and cooling are completed simultaneously the moment it comes into contact with the hot aluminum material. In this way, the profile is cooled and shaped while being rolled, avoiding the impact of the heat from the aluminum material on the equipment in traditional multi-layer continuous rolling.

[0043] 3. Water flows within the circulating water tank. A water pump draws water from the circulating water tank, and the water flows along the supply pipe into the drain pipe and supply pipe, then along the inlet pipe into the inner conveying pipe, and finally into the interior of the rolling shell through the inlet hole. After heat exchange, the water flows through the return hole into the gap between the inner conveying pipe and the return pipe, flowing back to the circulating water tank along the side of the support bracket. A limiting ring prevents the return pipe from excessively entering the rolling shell, aiding in heat exchange within the rolling shell. The inner conveying pipe and the return pipe continuously remove heat from the interior of the rolling shell, ensuring continuous heat dissipation for the aluminum material. Simultaneously, the rolling shell rotates, guiding the water flow during the rolling process, enabling automatic heat dissipation during rolling, and the water supply speed varies with the rolling speed.

[0044] 4. The water reservoir stores the water flow at the bottom. A partition separates the water flow. The circulating hot water enters the return baffle via the side of the support bracket, and then enters the water reservoir. The water flows along the partition to the position of the water reservoir below the support base, where it is dissipated by agitation. A support plate at the top of the support base continuously supports the aluminum material, and a guide groove guides and supports the aluminum material, ensuring it is positioned during rolling and preventing it from slipping out. This also ensures full contact between the aluminum material and the rolling shell, thus completing cooling and shaping during the rolling process. Attached Figure Description

[0047] Example 1, please refer to Figures 1-2 This invention provides a technical solution: a special mechanical device for continuous rolling of aluminum alloys. A fixed frame 1 provides overall support for the equipment. A circulating water tank 2 stores and circulates cooling water for cooling. A support frame 3 supports and guides the aluminum material. The workpiece is rolled step by step by a rolling device 4. A motor 402 is started, and the drive shaft of the motor 402 drives the agitator blades 403 to rotate. The rotation of the agitator blades 403 drives the water flow into the interior of the water supply pipe 405, and drives the rolling wheel 404 to rotate through the agitator blades 403. A support bracket 401 supports the rolling wheel 404 and the water supply pipe 405. The profile is continuously rolled by the extrusion of multiple sets of rolling wheels 404. The intervention of cooling water reduces the impact of high temperature during profile rolling, avoiding the impact of high temperature caused by long-term continuous rolling on the equipment. The material is rolled instantaneously during the melting process, thereby stabilizing the quality of the aluminum material. The aluminum material is hardened by water cooling, thereby stabilizing the quality of the aluminum material, shortening the rolling cycle, and improving production efficiency.

[0048] Example 2, please refer to Figures 1-4 Based on the first embodiment, the motor 402 is started. The drive shaft of the motor 402 rotates, driving the drive gear 4031 to rotate. The rotation of the drive gear 4031 drives the drainage blades 4033 to rotate. The rotation of the drainage blades 4033 causes the water to flow along the interior of the circulating water tank 2. The rotation of the drive gear 4031 drives the belt drive assembly 4032 to rotate. The rotation of the belt drive assembly 4032 drives the water supply pipe 405 to rotate, facilitating water circulation. The rotation of the drive gear 4031 drives the driven gear 4045 to rotate. When the driven gear 4045 rotates, the water flows along the water supply pipe 405. The water is introduced into the interior of the rolling shell 4041, and flows within the circulation cavity 4042. The guide ring 4043 restricts the movement trajectory of the aluminum material, which moves under the guidance of the guide ring 4043. The heat dissipation holes 4044 facilitate heat dissipation, allowing the water to circulate within the rolling shell 4041. The surface of the rolling shell 4041 is cooled, and rolling and cooling occur simultaneously with the high-temperature aluminum material. This allows for cooling and shaping of the profile while rolling, avoiding the impact of the aluminum material's heat on the equipment during traditional multi-layer continuous rolling.

[0049] Example 3, please refer to Figures 1-6 Based on the second embodiment, the rotation of the drive gear 4031 drives the drainage blade 4033 to rotate, and the rotation of the drainage blade 4033 drives the water flow along the interior of the circulating water tank 2. The rotation of the drive gear 4031 drives the belt drive assembly 4032 to rotate, and the rotation of the belt drive assembly 4032 drives the water pump 4052 to rotate. The water pump 4052 draws water from the interior of the circulating water tank 2. The water flows along the water supply pipe 4051 into the interior of the drain pipe 4053 and the water supply pipe 4054. The water flows along the water inlet pipe 40543 into the interior of the inner conveying pipe 40541 and then through the water inlet hole 40542 into the interior of the rolling shell 4041. After heat exchange, the water flows through the return water hole 40546 into the inner conveying pipe 40541 and the return water pipe 40544. The water flows back into the circulating water tank 2 through the gap along the side of the support bracket 401. The setting of the limiting ring 40545 restricts the return water pipe 40544 from entering the interior of the rolling shell 4041, and exchanges heat with the rolling shell 4041. The continuous heat dissipation inside the rolling shell 4041 is achieved through the inner conveying pipe 40541 and the return water pipe 40544, which facilitates continuous heat dissipation of the aluminum material. The rolling shell 4041 is driven to rotate by the drive gear 4031. During the rolling process of the aluminum material, the water flow is guided by the linkage between the drive gear 4031 and the rolling shell 4041, which facilitates automatic heat dissipation during the rolling process and achieves different water supply speeds according to the rolling speed.

[0050] Example 4, please refer to Figures 1-8 Based on the third embodiment, the water storage tank 201 stores the water flow at the bottom, and the partition plate 202 divides the water flow. The circulating hot water passes through the side of the support bracket 401, through the side of the circulation hole 203, into the interior of the return baffle 204, and into the interior of the water storage tank 201. The water flow flows along the partition plate 202 to the position of the water storage tank 201 below the support base 301, and is driven by the belt drive assembly 4032 to stir and dissipate heat. The support plate 302 set on the top of the support base 301 continuously supports the aluminum material, and guides and supports the aluminum material through the guide groove 303. This facilitates the aluminum material to be guided and positioned during the rolling process at the top of the guide groove 303, avoiding the possibility of the aluminum material coming off, and ensuring that the aluminum material is in full contact with the rolling shell 4041, so that the aluminum material can be cooled and shaped during the rolling process.
