Description

Technical Field

[0001] The present invention relates to the technical field of aluminum product production, and in particular to an aluminum tube continuous extrusion forming device and a production method thereof. Background Art

[0002] With the rapid development of new energy battery technology, the market demand for materials used in new energy battery poles is increasing. The pole is a wiring terminal in a new energy battery and is a component that connects the inside and outside of the battery. One end of the pole is connected to the battery core inside the battery, and the other end is connected to the circuit outside the battery, enabling the battery to perform the functions of charging and discharging. As a material for new energy battery poles that can reduce weight and cost, the quality of aluminum wire seriously affects the service life and safety performance of new energy batteries. During the production process of aluminum wire, an extrusion forming device is required to process and form the aluminum wire.

[0003] The existing production of aluminum wire generally adopts a method combining extrusion rod forming, cold heading treatment and machining. However, the dimensional accuracy of aluminum wire is generally low, and the hardness cannot reach the established standard. In the cold heading treatment process, due to uneven material fluidity or poor operating conditions of the cold heading machine, the aluminum wire is prone to uneven extrusion pressure in the mold, resulting in an unsmooth cold heading process. This not only destroys the internal microstructure of the aluminum wire and affects its mechanical properties, but also causes serious burr problems in the subsequent machining process. These burrs not only affect the appearance beauty of the aluminum wire, but also pose a direct threat to the quality stability of the pole.

[0031] Example: The technical solution of the present invention will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. Please refer to Figures 1 to 6 An aluminum tube continuous extrusion molding device provided by the present application. Please pay special attention to Figure 1, including a wire pay-off machine 1; a straightening machine 2 is installed at one end of the wire pay-off machine 1, and the straightening machine 2 is used to straighten the aluminum rod.

A traction machine 7 is installed at the end of the length counter 9 away from the drying device 6, and the traction machine 7 is used to guide and direct the aluminum tube after passing through the drying device 6. A winding device 8 is installed at the end of the traction machine 7 away from the drying device 6, and the winding device 8 is used to wind up the aluminum tube.

[0032] Specifically, the wire pay-off machine 1 is used to store and gradually release the aluminum rod materials to be processed. The straightening machine 2 is used to straighten the aluminum rod released from the wire pay-off machine 1. By applying pressure to the aluminum rod, the bent part gradually becomes straight, providing high-quality raw materials for subsequent processing. The cleaning machine 3 is used to remove impurities such as dirt and oxides that may exist on the surface of the aluminum rod, providing a clean surface for subsequent extrusion molding. The extrusion molding machine 4 extrudes the cleaned aluminum rod into the required aluminum tube shape through high temperature and high pressure. The cooling device 5 is used to quickly cool the extruded aluminum tube to prevent it from deforming or generating internal stress due to high temperature. The drying device 6 is used to remove the moisture or cleaning agent that may remain on the surface of the aluminum tube, ensuring that the product is dry. The length counter 9 is used to accurately measure the length of the aluminum tube. The length counter 9 adopts a roller-type measurement method. The traction machine 7 is used to guide and direct the dried aluminum tube to ensure its stable running trajectory during subsequent processing. The winding device 8 is used to wind up and store the aluminum tube after all processing procedures, facilitating subsequent transportation and use. The aluminum rod is unrolled from the wire pay-off machine 1 and then transported to the straightening machine 2 for straightening. The aluminum rod after being straightened by the straightening machine 2 is transported into the cleaning machine 3, and the cleaning machine 3 cleans the dust on the outer surface of the aluminum rod. The cleaned aluminum rod is transported into the extrusion molding machine 4 and extruded into an aluminum tube through a die. Then the aluminum tube is transported into the cooling device 5 for cooling treatment and then transported into the drying device 6 for drying treatment. The aluminum tube after being dried by the drying device 6 is measured for length by the length counter 9 and guided by the traction machine 7 and the guiding device 701, and then transported to the winding device 8 for winding, realizing the full-process automated production of the aluminum rod from wire pay-off, straightening, cleaning, extrusion molding, cooling, drying, length measurement, traction to winding, greatly improving the production efficiency and product quality.

[0033] Please refer particularly to Figure 2 , the wire pay-off machine 1 includes a wire pay-off rack 101, a raw material roller 102 and a guiding roller 103. One end of the wire pay-off rack 101 is rotatably installed with the raw material roller 102, and the guiding roller 103 is installed inside the wire pay-off rack 101. The wire pay-off rack 101 is the main part that supports the entire structure of the wire pay-off machine, usually made of strong and durable metal materials to ensure sufficient stability and load-bearing capacity during long-term continuous operation. The wire pay-off rack 101 allows the raw material roller 102 to be rotatably installed inside it, providing the necessary support for the continuous supply of aluminum bars. The raw material roller 102 stores aluminum bars, is installed inside the wire pay-off rack 101, and is rotated by a motor to continuously convey the aluminum bars to the subsequent processing procedures. The guiding roller 103 is installed on the top of the wire pay-off rack 101, and its main function is to ensure that the aluminum bars released from the raw material roller 102 can advance smoothly along a predetermined path.

[0034] Specifically, to ensure the continuous and stable supply of aluminum bars and provide a reliable material guarantee for the subsequent extrusion forming process, the raw material roller 102 starts to rotate. As the raw material roller 102 rotates, the aluminum bars gradually unwind from the roller and advance along the path set by the guiding roller 103. Under the continuous rotation of the raw material roller 102, the aluminum bars are conveyed to the subsequent extrusion forming process. The presence of the guiding roller 103 ensures the stability and accuracy of the aluminum material during transportation, avoiding production interruptions caused by material skewing or knotting.

[0035] Please refer particularly to Figure 3 , the straightening machine 2 includes a machine frame 201, straightening wheels 202 and a straightening belt 203. One end of the wire pay-off machine 1 is installed with the machine frame 201. The straightening wheels 202 are installed at the central position inside the machine frame 201, and the straightening belt 203 is installed at both ends inside the machine frame 201 near the straightening wheels 202. The machine frame 201 is the main structure of the straightening machine 2, which supports the entire straightening system. When the material passes through the straightening wheels 202, the rotation and precise arrangement of the straightening wheels 202 will apply appropriate pressure and bending to the material, gradually eliminating the original bending and twisting. The straightening belt 203 is usually installed at both ends inside the machine frame 201 near the straightening wheels 202 to further assist the straightening process.

[0036] Specifically, in order to straighten the aluminum rod to ensure that its straightness meets specific process or application requirements, when the aluminum rod is fed from the wire pay-off machine 1 into the straightening machine 2, it first enters the straightening channel composed of the straightening wheels 202 and the straightening belt 203. The straightening wheels 202 rotate at a certain speed and direction, applying pressure and bending to the material. The directions of these pressures and bends alternate, causing the material to experience a series of small bends and reverse bends when passing through the straightening wheels 202. These bends gradually cancel out the original bends and twists of the material, making it straighter. At the same time, the straightening belt 203 acts on the material through friction and tension, further helping the material to maintain a straight state.

[0037] Please refer specifically to Figure 4 The cleaning machine 3 includes a cleaning box 301, cleaning brushes 302, and a suction fan 303. A cleaning box 301 is installed at one end of the straightening machine 2 away from the wire pay-off machine 1. A plurality of groups of cleaning brushes 302 are rotatably installed inside the cleaning box 301. The plurality of groups of cleaning brushes 302 are arranged symmetrically up and down. A suction fan 303 is fixedly installed at the bottom of the cleaning box 301. The cleaning box 301 is the main structure of the cleaning machine 3, providing a closed or semi-closed working environment for accommodating the cleaning brushes 302 and the material of the aluminum rod. The cleaning brushes 302 are composed of, for example, nylon material. The plurality of groups of cleaning brushes 302 are arranged symmetrically up and down, ensuring that both the upper and lower surfaces of the aluminum rod can be fully cleaned when passing through the cleaning box 301. The suction fan 303 is used to generate negative pressure, sucking in the impurities and dust generated during the cleaning process and discharging them out of the system through a pipeline.

[0038] Specifically, in order to effectively clean the surface of the aluminum rod, remove impurities such as metal chips and dust, and ensure the smooth progress of subsequent processing steps and the quality of the final product, when the material is straightened by the straightening machine 2, it enters the cleaning box 301 of the cleaning machine 3. Inside the cleaning box 301, a plurality of groups of cleaning brushes 302 arranged symmetrically up and down start to rotate, contacting the surface of the aluminum rod and removing the impurities thereon. At the same time, the suction fan 303 starts to work, generating negative pressure to suck in the impurities and dust generated during the cleaning process and discharging them out of the system through a pipeline, avoiding secondary pollution of the material.

[0039] Please refer specifically to Figure 1, the cooling device 5 includes a cooling tank 501 and a conveying roller 502. A cooling tank 501 is installed at one end of the extrusion molding machine 4 away from the cleaning machine 3. The inside of the cooling tank 501 stores a coolant. A conveying roller 502 is installed inside the cooling tank 501. The cooling tank 501 is the main part of the cooling device 5. It stores a coolant inside, which is used to absorb and take away the heat on the aluminum tube. Usually, a coolant with good thermal conductivity and chemical stability is selected. The conveying roller 502 is responsible for smoothly feeding the aluminum tube into the cooling tank 501 and keeping it continuously moving during the cooling process to ensure uniform cooling effect. The conveying roller 502 is driven by a motor to rotate and feed the aluminum tube into the cooling tank 501 at a certain speed and direction. During the cooling process, the conveying roller 502 continues to rotate to ensure that the aluminum tube moves uniformly in the coolant, thereby achieving uniform cooling.

[0040] Specifically, in order to achieve efficient and uniform cooling of the aluminum tube, stabilize the organizational structure of the aluminum material, prevent deformation and cracking, and at the same time improve the hardness and strength of the material, providing high-quality semi-finished products for subsequent processing steps, the high-temperature aluminum tube after extrusion molding and cleaning is fed into the cooling tank 501. Under the guidance of the conveying roller 502, the aluminum tube smoothly enters the coolant. When the aluminum tube contacts the coolant, the coolant quickly absorbs the heat on the aluminum tube through heat conduction. Under the action of the coolant, the temperature of the aluminum tube rapidly decreases, its organizational structure is stabilized, preventing the occurrence of deformation and cracking. At the same time, the hardness and strength of the material are improved, providing high-quality semi-finished products for subsequent processing steps. The aluminum tube after sufficient cooling leaves from the other end of the cooling tank 501 and is ready to enter the subsequent processing steps. Through the coordinated action of the cooling tank 501 and the conveying roller 502, the cooling device 5 can quickly cool the high-temperature aluminum tube to an appropriate temperature, ensuring the stability of the organizational structure of the material, and the improvement of hardness and strength.

[0041] Please refer specifically to Figure 6 , two sets of water squeezing rollers 10 are rotatably installed at one end of the drying device 6 close to the cooling device 5. An air storage device 1001 is installed on the outer side of one end of the water squeezing roller 10. An air plate 1002 is installed on the top of the drying device 6 close to the water squeezing roller 10. The rotation of the water squeezing roller 10 wipes off the excess water on the outer surface of the aluminum tube, reducing the drying burden and improving the drying efficiency. The air storage device 1001 is composed of a box body and a built-in fan blade. When the rotation of the water squeezing roller 10 drives the fan blade to rotate, the box body is used to collect and store the airflow generated by the fan blade. When the fan blade operates, it inhales the outside air and accelerates its flow, forming an air current with a certain speed and pressure, which is stored in the box body, and then the airflow generated by the air storage device 1001 is guided to the area of the water squeezing roller 10 through a pipeline.

[0042] Specifically, in order to quickly and effectively remove the moisture on the surface of the aluminum tube, the water squeezing roller 10 is composed of two sets of relatively rotating rollers. When the wet aluminum tube passes through the water squeezing roller 10, the two sets of water squeezing rollers 10 cooperate closely. The rotation of the water squeezing roller 10 can wipe off the excess moisture on the outer surface of the aluminum tube, reduce the drying burden, and improve the drying efficiency. This step reduces the moisture content on the surface of the aluminum tube and prepares for the subsequent drying. At the same time, the fan blades of the air storage device 1001 keep running under the action of the rotation of the water squeezing roller 10, inhale the external air and accelerate its flow, form a strong air current and store it in the box body. With the accumulation of the air pressure in the box body, the air current is precisely guided to the working area of the water squeezing roller 10 through the air plate 1002 to dry the water squeezing roller 10, which can improve the drying efficiency of the subsequent drying device 6 for the aluminum tube.

[0043] Please refer specifically to Figure 6 , one end of the water squeezing roller 10 is installed with a spring column 1003, one end of the spring column 1003 is installed with a scraper 1004, one end of the air plate 1002 is installed with a conduit 1005, and the air outlet end of the conduit 1005 is located on one side of the scraper 1004. The spring column 1003 is installed at one end of the water squeezing roller 10, and its main function is to provide an adjustable support structure for installing the scraper 1004. The spring column 1003 allows the scraper 1004 to have a certain elastic deformation when under pressure. The scraper 1004 can further remove the trace moisture or impurities remaining on the surface of the water squeezing roller 10. The conduit 1005 is to precisely guide the air current generated by the air storage device 1001 to the outside of the scraper 1004, apply pressure to the scraper 1004, and make the scraping end of the scraper 1004 fit the outer surface of the water squeezing roller 10.

[0044] Specifically, in order to process the outer surface of the water squeezing roller 10, when the wet aluminum tube passes through the water squeezing roller 10, the water squeezing roller 10 first wipes off most of the moisture. Subsequently, the conduit 1005 precisely guides the air current generated by the air storage device 1001 to the outside of the scraper 1004, applies pressure to the scraper 1004, the spring column 1003 moves, and makes the scraping end of the scraper 1004 fit the outer surface of the water squeezing roller 10. The trace moisture or impurities remaining on the surface of the water squeezing roller 10 can be further removed through the scraper 1004.

[0045] Please refer specifically to Figure 5 , the drying device 6 includes a drying box 601, a wind guiding plate 602 and a fan 603. The drying box 601 is installed at one end of the cooling device 5 far away from the extrusion molding machine 4. The inner top of the drying box 601 is installed with the wind guiding plate 602, and the top of the drying box 601 is installed with the fan 603. The drying box 601 is the main structure of the drying device 6, which provides a closed or semi-closed space for accommodating the aluminum tube to be dried. The fan 603 is responsible for accelerating the air flow in the drying box 601, and the wind guiding plate 602 diffuses the wind generated by the fan 603 and transfers it to the inside of the drying box 601 to remove the moisture on the surface of the aluminum tube.

[0046] Specifically, in order to achieve efficient and uniform drying of the aluminum tubes, remove the residual moisture or coolant on the surface, ensure that the aluminum tubes are in a dry state before entering the subsequent processing steps, and avoid corrosion, oxidation or other quality problems caused by residual moisture, the aluminum tubes after cooling treatment are sent into the drying oven 601. At the same time, the fan 603 is started to accelerate the air flow in the drying oven 601, and the air guiding plate 602 diffuses the air generated by the fan 603 and transfers it into the drying oven 601, which helps to accelerate the evaporation of moisture on the surface of the aluminum tubes and the drying speed. At this time, the fan 603 discharges the evaporated moisture and heat from the drying oven 601 to maintain a dry and suitable temperature in the internal environment. After being fully dried, the aluminum tubes leave from the other end of the drying oven 601 and are ready to enter the subsequent processing steps. Through the synergistic effect of the air guiding plate 602 and the fan 603, the drying device 6 can quickly evaporate the moisture on the surface of the aluminum tubes and improve the drying efficiency.

[0047] Please refer specifically to Figure 1 , a guiding device 701 is installed at one end of the tractor 7 away from the drying oven 601. The guiding device 701 is used to guide and convey the aluminum tubes to the winding device 8. The tractor 7 is a device used to provide stable traction force on the continuous production line of aluminum tubes. It ensures that the aluminum tubes maintain a constant speed and tension during the conveying process, and avoids problems such as material deformation, fracture or winding caused by speed fluctuations or uneven tension. The guiding device 701 is composed of multiple groups of guiding rollers and is responsible for smoothly guiding the aluminum tubes from the tractor 7 to the winding device 8.

[0048] Specifically, in order to achieve stable conveying and precise guiding of the aluminum tubes, the aluminum tubes processed by the drying oven 601 come out from the outlet of the drying oven 601 and first enter the tractor 7. The tractor 7 starts to rotate under the action of its own driving force and contacts the aluminum tubes to generate a traction force to traction and convey the aluminum tubes. During the conveying process, the guiding device 701 ensures that the aluminum tubes maintain straightness and position stability. Under the traction force of the tractor 7 and the guiding action of the guiding device 701, the aluminum tubes are smoothly conveyed to the winding device 8 for winding and collection, providing high-quality semi-finished products for subsequent storage or further processing.

[0049] On the other hand, the embodiment of the present application also provides a production method for continuous extrusion molding of aluminum tubes according to the above, including the following steps: S1: The aluminum rod is unrolled from the wire pay-off machine 1 and then conveyed to the straightening machine 2 for straightening; S2: The aluminum rod straightened by the straightening machine 2 is conveyed into the inside of the cleaning machine 3, and the cleaning machine 3 cleans the dust on the outer surface of the aluminum rod; S3: The cleaned aluminum rod is conveyed into the inside of the extrusion molding machine 4 and extruded into aluminum tubes through a die and discharged; S4: Then the aluminum tube will be transported to the inside of the cooling device 5 for cooling treatment and then to the inside of the drying device 6 for drying treatment; S5: The aluminum tube dried by the drying device 6 is measured in length by the length counter 9, guided by the tractor 7 and the guiding device 701, and then transported to the winding device 8 for winding.

[0050] Working principle: The raw material roller 102 starts to rotate. As the raw material roller 102 rotates, the aluminum bar gradually unfolds from the roller and advances along the path set by the guiding roller 103. Under the continuous rotation of the raw material roller 102, the aluminum bar is transported to the frame 201. When the aluminum bar is fed from the wire pay-off machine 1 into the straightening machine 2, it first enters the straightening channel composed of the straightening wheels 202 and the straightening belt 203. The straightening wheels 202 rotate at a certain speed and direction, applying pressure and bending to the material. The directions of these pressures and bends alternate, causing the material to experience a series of small bends and reverse bends when passing through the straightening wheels 202. At the same time, the straightening belt 203 acts on the material through friction and tension to further help the material maintain a straight state. After the material is straightened by the straightening machine 2, it enters the cleaning box 301 of the cleaning machine 3. The cleaning brush 302 starts to rotate, contacts the surface of the aluminum bar and removes the impurities thereon. At the same time, the suction fan 303 starts to work, generating a negative pressure to suck the impurities and dust generated during the cleaning process and discharging them out of the system through the pipeline. The high-temperature aluminum tube after extrusion molding and cleaning is sent into the cooling tank 501. Guided by the conveying roller 502, the aluminum tube smoothly enters the coolant. When the aluminum tube contacts the coolant, the coolant quickly absorbs the heat on the aluminum tube by heat conduction. Under the action of the coolant, the temperature of the aluminum tube drops rapidly. The aluminum tube after cooling treatment is sent into the drying box 601. At the same time, the fan 603 starts to accelerate the air flow in the drying box 601. The air guiding plate 602 diffuses the air generated by the fan 603 and transfers it to the inside of the drying box 601 to accelerate the evaporation of moisture and the drying speed on the surface of the aluminum tube. Then the length of the aluminum tube can be accurately measured by the length counter 9, guided by the tractor 7 and the guiding device 701, and transported to the winding device 8 for winding.
