Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil rolling, in particular to aluminum alloy foil rolling processing equipment. Background Art

[0002] Aluminum alloy foil can be divided into thick foil, single zero foil and double zero foil according to thickness. Thick foil has a thickness of 0.1-0.2 mm and is attached to the inside of the streamlined car shell, which helps to conduct heat from the inside of the car over a large area and avoid deformation caused by excessive local heat in the car shell. The existing application number is CN202410573539.X, which is suitable for the calendering device and method of lithium-ion battery aluminum foil forming. The patent document discloses a roller with a cylindrical structure to thin the aluminum foil, optimize the internal structure of the roller, and deal with the degreasing and lubricating oil replenishment operations on the surface of the aluminum foil. Specifically: the rollers on both sides of the aluminum foil are used to extrude the aluminum foil, and the rollers rotate to calender the thin aluminum plate passing through into aluminum foil. The rotating drum rotates accordingly so that the pressure nozzle passes through the working position in turn, and the rubber block moves into the corresponding extrusion cavity. During the movement of the extrusion cavity, the rubber block extrudes the air inside the extrusion cavity. The pressure in the extrusion chamber increases as the pressure decreases. After reaching the critical pressure value of the pressure nozzle, the pressure nozzle sprays the heated solution in atomized form. When the solution is a cleaning agent, the pressure nozzle nozzle is installed with a certain angle to the center axis of the roller. The pressure nozzles on both sides spray the solution toward the aluminum foil at the same time to clean the rolling lubricant remaining on the surface of the aluminum foil. When the solution is rolling lubricant, the pressure nozzle nozzle is installed in parallel with the center axis of the roller. The pressure nozzles extending from both sides spray the solution toward the surface of the roller at the same time to supplement the rolling lubricant on the surface of the roller. However, when using the technical solution in the above patent document, although the thickness of the aluminum foil can be ensured to be uniform, it is impossible to implement calendering for the aluminum alloy foil with the heat dissipation requirement on the inner side of the streamlined automobile shell. If the flat aluminum foil is directly used for the automobile shell, problems such as poor fitting will occur. Since the automobile shell is not a completely flat shape, the flat aluminum foil cannot adapt well to its curved surface, and gaps or wrinkles are easily generated during the fitting process. These gaps and wrinkles will not only affect the aesthetics of the automobile shell, but may also further affect the heat dissipation effect. Therefore, the present application provides an aluminum alloy foil calendering processing equipment. Summary of the invention

[0024] Embodiment 1: like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, this embodiment provides an aluminum alloy foil rolling processing equipment, including a feeding table 11 and a rolling frame 21, wherein a foil 1 is placed on the feeding table 11, and a plurality of rollers 12 for conveying the foil 1 are rotatably mounted on the feeding table 11, and a motor IV for driving the rollers 12 to rotate is also mounted on the feeding table 11, and the motor IV is started to control the rotation of the rollers 12 to convey the foil 1; a roller plate 23 is rotatably mounted on the rolling frame 21, and the foil 1 extends to the bottom of the roller plate 23 for conveying An annular seat 32 is fixedly installed on the outer side of the end of the calendering frame 21 through a connecting rib plate 31. A plurality of side extension arms 33 are provided on the outer side of the annular seat 32. A positioning arm 34 and a first linear electric cylinder 35 for driving the positioning arm 34 to slide are installed in the side extension arm 33. The sliding trajectory of the positioning arm 34 extends toward the rotation center of the roller plate 23. A U-shaped frame 36 is fixedly installed on the positioning arm 34. A pressure roller 37 is rotatably installed on the U-shaped frame 36. The pressure roller 37 can abut against the outer side surface of the connecting rib plate 31.

[0025] The plurality of rollers 12 are divided into two groups, an upper group and an lower group. The two groups of rollers 12 are respectively located at the upper and lower sides of the foil 1 and abut against the outer side surface of the foil 1 to increase the conveying stability of the foil 1 .

[0026] Among them, sleeves 22 are respectively provided on both sides of the top of the calendering frame 21, and shafts 24 are respectively fixedly installed on both ends of the roller plate 23, and the shaft 24 is rotatably connected with the sleeve 22; by extending the length of the sleeve 22 and the shaft 24, the supporting stability of the calendering frame 21 for the roller plate 23 is increased.

[0027] like Fig. 9 , Fig.10 and Fig.11As shown, a plurality of articulated seats 42 are fixedly installed at one end of the roller pressure plate 23 away from the annular seat 32, and a traction clamping arm 43 is rotatably installed on each articulated seat 42. A circular ring 41 is fixedly installed inside the roller pressure plate 23, and a second linear electric cylinder 44 is installed between the circular ring 41 and the traction clamping arm 43. The fixed end and the movable end of the second linear electric cylinder 44 are rotatably connected to the circular ring 41 and the traction clamping arm 43 respectively. When the second linear electric cylinder 44 is started, the traction clamping arm 43 is smoothly inserted between two adjacent pressure rollers 37 and abuts against the outer side surface of the roller pressure plate 23.

[0028] Among them, the power supply lines of the multiple second linear electric cylinders 44 can be connected to the external power supply equipment using a conductive slip ring. The conductive slip ring is composed of an electric ring and a brush to ensure that the second linear electric cylinders 44 can still be powered during the synchronous rotation of the annular seat 32 and the multiple traction clamp arms 43; or the power supply line of the second linear electric cylinder 44 is connected to the built-in battery of the annular seat 32 to provide driving power for the second linear electric cylinder 44.

[0029] like Figure 1 , Figure 2 , Figure 6 and Fig.12 As shown, a swivel arm 51 and a motor II 52 for driving the swivel arm 51 to rotate are installed on the upper side of the annular seat 32, a pressing and cutting table 53 and a third linear electric cylinder 54 for driving the pressing and cutting table 53 to move vertically are installed on the swivel arm 51, and a cutting blade 532 is integrally formed on the bottom edge of the pressing and cutting table 53, and the cutting blade 532 can abut against the outer side surface of the roller pressure plate 23.

[0030] like Figure 2 and Figure 5 As shown, a recovery groove 13 is detachably fixedly mounted on the upper side of the feeding platform 11 , and the end of the recovery groove 13 abuts against the outer side surface of the roller plate 23 .

[0031] The details of the aluminum alloy foil rolling process using the aluminum alloy foil rolling process equipment of the present application are as follows: 1. Preparation before use: A laser roughness meter is used to detect the surface finish of the rotating roller 12, the roller plate 23 and the pressure roller 37 to prevent dust adhesion from affecting product quality. The working condition of the traction clamp arm 43 is detected, and a torque sensor is used to check whether the traction clamp arm 43 rotates smoothly. During the rotation of the traction clamp arm 43, a laser rangefinder is used to detect and observe the distance between the edge of the traction clamp arm 43 and the outer side of the pressure roller 37 to prevent motion interference.

[0032] 2. Pull the foil 1 from the feeding platform 11 to the roller plate 23: First, the roller 12 on the feeding platform 11 is controlled to rotate to convey the foil 1 so that the end of the foil 1 extends to the bottom of the roller plate 23; Afterwards, the roller platen 23 and the plurality of traction clamp arms 43 are controlled to rotate synchronously. During this process, the traction clamp arms 43 located below the side of the feeding platform 11 are controlled to rotate, so as to push the end of the foil 1 toward the outer side of the roller platen 23 and press it, thereby completing the preliminary traction operation of the foil 1 from the feeding platform 11 to the roller platen 23. Finally, as the roller plate 23 continues to rotate, the corresponding traction clamp arms 43 and the roller plate 23 are kept pressing the end of the foil 1 , so that the foil 1 gradually covers one-half to two-thirds of the area outside the roller plate 23 .

[0033] 3. Roll forming the foil 1: The roller platen 23 is kept rotating. At the same time, the pressure roller 37 is controlled to rotate on the U-shaped frame 36, and the distance between the pressure roller 37 and the outer side surface of the roller platen 23 is adjusted. The foil 1 is rolled using the outer contours of the roller platen 23 and the pressure roller 37, so that the portion where the foil 1 abuts against the roller platen 23 forms a curved surface area 2, thereby completing the roll forming process of the foil 1.

[0034] During this process, the distance between the pressure roller 37 near the traction clamp arm 43 corresponding to the end of the foil 1 and the outer side of the roller pressure plate 23 is adjusted in sequence to avoid the traction clamp arm 43 and prevent the pressure roller 37 from colliding with the traction clamp arm 43.

[0035] 4. Cutting the aluminum alloy foil with a curved surface structure from the foil material 1: First, the rotation of the roller platen 23 and the pressure roller 37 is stopped, and the third linear electric cylinder 54 is started to control the pressing and cutting table 53 to move downward, so that the cutting blade 532 abuts against the foil material 1, and the aluminum alloy foil with a curved surface structure is cut from the foil material 1. A silicone pad 531 is detachably provided on the middle side of the bottom of the pressing and cutting table 53, so that the silicone pad 531 can be fully fitted with the outer side of the foil material 1, providing a static adsorption basis, so that the cut aluminum alloy foil is subjected to the surface adsorption effect and stably adheres to the bottom of the silicone pad 531, thereby realizing efficient picking and transfer; Afterwards, the motor II 52 is started to drive the rotating arm 51 and the pressing and cutting table 53 to rotate together, and the aluminum alloy foil at the bottom of the silicone pad 531 is removed manually or using an industrial-grade robot so that the pressing and cutting table 53 can perform subsequent aluminum alloy foil cutting operations.

[0036] 5. Implement waste recycling of foil 1: The roller pressure plate 23 and the pressure roller 37 are controlled to rotate again, and the remaining foil 1 after the aluminum alloy foil is cut is pulled and moved to the upper side of the recovery groove 13. Since the end of the recovery groove 13 abuts against the outer side of the roller pressure plate 23, the remaining foil 1 after the aluminum alloy foil is cut is accumulated on the recovery groove 13, completing the waste material recovery operation of the foil 1, so that the foil 1 outside the roller pressure plate 23 will not overlap multiple layers.

[0037] By using the above scheme of the present application, an aluminum alloy foil with a curved surface structure is calendered and processed, and its contoured surface is used to accurately fit the inner wall contour of the streamlined vehicle body shell, thereby avoiding the increase in thermal resistance caused by local wrinkles in the material, ensuring the efficient thermal conductivity of the vehicle thermal management system, and avoiding deformation of the vehicle body shell due to local overheating.
