Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum strip processing, and specifically relates to a double-sided oil spraying device for aluminum strip. Background Technology
[0002] Battery casings for new energy vehicles are typically made of lightweight aluminum with a rectangular cross-section. The manufacturing process involves extruding aluminum strips, a highly efficient, low-cost process suitable for mass production, especially for battery casings with elongated cross-sections.
[0003] The process of manufacturing new energy vehicle battery casings by aluminum strip extrusion molding is as follows: 1. Select aluminum alloy coils, typically 1.5~6mm thick, as aluminum strips; 2. Continuous extrusion: After preheating (300~450℃), the aluminum strip enters the extrusion die and is formed into a closed rectangular cross-section shape under high pressure of 100~500MPa; 3. Online cooling: Water cooling or air cooling for shaping, controlling the grain size (refining to 10~20μm) to improve strength; 4. Finishing and cutting: Straightening, flying shearing, or laser cutting to the required length. The disadvantage of this aluminum strip extrusion molding process for manufacturing new energy vehicle battery casings is that the lack of oil lubrication before extrusion makes the aluminum strip prone to sticking to the extrusion die, causing damage to both the aluminum strip and the die. Utility Model Content
[0004] The purpose of this invention is to provide a double-sided oil spraying device for aluminum strips, which can spray oil onto the aluminum strips to be processed, preventing the aluminum strips from sticking to the mold during processing and protecting both the aluminum strips and the molds.
[0005] The purpose of this utility model is achieved as follows: A double-sided oil spraying device for aluminum strip includes a base, on which corresponding front and rear inlet and outlet mechanisms are provided. Two sets of corresponding centering mechanisms are provided on the base between the inlet and outlet mechanisms. Protective covers are provided on the base corresponding to the inlet, outlet and centering mechanisms. Inlet and outlet ports are respectively opened on the front and rear sides of the protective covers. A hydraulic pump station is provided corresponding to the protective covers. Two oil outlet pipes are provided on the hydraulic pump station. An oil spraying cavity is provided inside the protective cover. Oil spraying ports are opened on both the left and right sides of the protective cover. Atomizing oil spray nozzles are provided at the ends of the two oil outlet pipes. The two atomizing oil spray nozzles are respectively provided for the two oil spraying ports. A return oil pipe is provided on the hydraulic pump station. The return oil pipe is connected to the bottom of the protective cover and communicates with the oil spraying cavity.
[0006] In operation, the aluminum strip is driven backward by the conveyor rollers. The strip enters the protective cover through the inlet, and is guided backward by the guide rollers of the infeed and discharge mechanisms. Two symmetrical centering rollers of the centering mechanism center the strip, and then the hydraulic pump station sprays oil onto the strip through the oil outlets on both sides of the protective cover via the oil pipe, thus lubricating the strip. Finally, the strip exits from the outlet of the protective cover. Compared with existing technologies, the advantages of this invention are: it can spray oil onto the aluminum strip to be processed, preventing the strip from sticking to the mold during processing, preventing friction between the strip and subsequent processing molds, and protecting both the strip and the mold.
[0007] As a further improvement of this utility model, both the infeeding mechanism and the outfeeding mechanism include two left-right corresponding guide seats, and two upper-lower corresponding guide rollers are rotatably arranged between the two guide seats, with a gap between the two guide rollers to allow the aluminum strip to pass horizontally. The upper and lower guide rollers guide the aluminum strip.
[0008] As a further improvement of this utility model, the centering mechanism includes a centering base, on which two slider seats that can move towards or away from each other are arranged symmetrically. Each slider seat has a pair of vertically mounted centering rollers that can be rotatably mounted on it. The centering rollers on the two slider seats can move synchronously towards or away from each other to align the left and right sides of the aluminum strip.
[0009] As a further improvement of this utility model, a longitudinal groove is formed on the centering machine base. A positive and negative threaded rod is rotatably mounted on the centering machine base within the groove. The ends of the positive and negative threaded rods extend out of the centering machine base and are equipped with handwheels. Positive thread nuts and negative thread nuts are respectively fitted onto the positive and negative threaded rods. The positive thread nuts and negative thread nuts are fixed to two slider seats, which are slidably connected to the inner wall of the groove. The handwheel drives the positive and negative threaded rods to rotate forward or backward, causing the positive thread nuts and negative thread nuts to move towards or in opposite directions, thereby controlling the synchronous movement of the centering vertical rollers on the two slider seats towards or in opposite directions.
[0010] As a further improvement of this utility model, the protective cover is rectangular and includes an upper side plate, a lower side plate, a left side plate, a right side plate, a front side plate, and a rear side plate. The height of the lower side plate is lower than the height of the upper surface of the base. The inlet and outlet are respectively located on the front and rear side plates, and the oil return pipe is connected to the lower side plate. The inlet and outlet of the protective cover are positioned corresponding to the aluminum strip. The oil spraying cavity inside the protective cover is used to contain oil, which is volatile oil. The oil sprayed from the atomizing nozzle falls onto the lower side plate, facilitating its return to the pump station via the oil return pipe. Attached Figure Description

[0018] like Figure 1-6 As shown, an aluminum strip double-sided oil spraying device includes a base 1, on which corresponding front and rear inlet and outlet mechanisms are provided. Two sets of corresponding centering mechanisms are provided on the base 1 between the inlet and outlet mechanisms. Protective covers 2 are provided on the base 1 corresponding to the inlet, outlet and centering mechanisms. Inlet ports 3 and outlet ports 4 are respectively opened on the front and rear sides of the protective covers 2. A hydraulic pump station 5 is provided corresponding to the protective covers 2. Two oil outlet pipes 6 are provided on the hydraulic pump station 5. An oil spraying cavity 7 is provided inside the protective covers 2. Oil spraying ports 8 are opened on both the left and right sides of the protective covers 2. Atomizing oil spray nozzles 9 are provided at the ends of the two oil outlet pipes 6. The two atomizing oil spray nozzles 9 are respectively provided corresponding to the two oil spraying ports 8. A return oil pipe 10 is provided on the hydraulic pump station 5. The return oil pipe 10 is connected to the bottom of the protective covers 2 and communicates with the oil spraying cavity 7. The protective cover 2 is rectangular and includes an upper side plate 2a, a lower side plate 2b, a left side plate 2c, a right side plate 2d, a front side plate 2e, and a rear side plate 2f. The height of the lower side plate 2b is lower than the height of the upper surface of the base 1. The inlet 3 and outlet 4 are respectively located on the front side plate 2e and the rear side plate 2f. The oil return pipe 10 is connected to the lower side plate 2b. The inlet 3 and outlet 4 of the protective cover 2 are set corresponding to the aluminum strip 21. The oil spraying cavity 7 inside the protective cover 2 is used to contain oil, which is volatile oil. The oil sprayed from the atomizing nozzle 9 falls onto the lower side plate 2b, making it easy to return to the pump station through the oil return pipe 10.
[0019] Both the infeeding mechanism and the outfeeding mechanism include two left and right corresponding guide seats 11. Two upper and lower corresponding guide rollers 12 are rotatably arranged between the two guide seats 11, and a gap is left between the two guide rollers 12 to allow the aluminum strip 21 to pass through horizontally. The upper and lower guide rollers 12 guide the aluminum strip 21.
[0020] The centering mechanism includes a centering base 13, on which two sliding blocks 14 are arranged symmetrically. Each sliding block 14 has a pair of vertically mounted centering rollers 15 that can rotatably move in opposite directions. The centering rollers 15 on the two sliding blocks 14 can move synchronously in opposite directions to align the left and right sides of the aluminum strip 21. A longitudinal groove 16 is formed on the centering base 13. A positive and negative threaded rod 17 is rotatably mounted on the centering base 13 and located within the groove 16. The ends of the positive and negative threaded rods 17 extend out of the centering base 13 and are equipped with handwheels 18. A positive thread nut 19 and a negative thread nut 20 are respectively fitted on the positive and negative threaded rods 17. The positive thread nut 19 and the negative thread nut 20 are fixed to the two sliding blocks 14, and the sliding blocks 14 are slidably connected to the inner wall of the groove 16. The handwheel 18 drives the forward and reverse threaded screws 17 to rotate forward or reverse, causing the forward threaded nut 19 and the reverse threaded nut 20 to move toward or in opposite directions, thereby controlling the centering vertical rollers 15 on the two slider seats 14 to move synchronously toward or in opposite directions.
[0021] In operation, the aluminum strip 21 is driven backward by the conveying rollers. The aluminum strip 21 enters the protective cover 2 through the feed inlet 3. The guide rollers 12 of the inlet and outlet mechanisms guide the aluminum strip 21 backward. Two symmetrical centering rollers 15 of the centering mechanism center the aluminum strip 21. Then, the hydraulic pump station 5 sprays oil onto the aluminum strip 21 through the oil outlet pipe 6 via the oil spray nozzles 8 on both sides of the protective cover 2, thus lubricating the aluminum strip 21. Finally, the aluminum strip 21 exits from the discharge outlet 4 of the protective cover 2. The advantages of this invention are: it can spray oil onto the aluminum strip 21 to be processed, preventing the aluminum strip 21 from sticking to the mold during processing, preventing friction between the aluminum strip 21 and subsequent processing molds, and protecting both the aluminum strip 21 and the mold.
