Technical Field

[0001] The utility model relates to the technical field of aluminum can processing, in particular to a metal plate curling device for aluminum can processing. Background Art

[0002] Aluminum can processing involves transforming aluminum into a finished can through a series of processes. First, the aluminum is initially formed through cutting and bending. Further processing is then performed through welding, bulging, and stretching to create the final can structure. Finally, surface treatments such as polishing, painting, and labeling enhance the can's appearance. Aluminum can processing offers advantages such as low cost, light weight, and ease of recycling. It is widely used in food and beverage packaging, cosmetic containers, and pharmaceutical packaging. This involves curling the metal sheet to form the can's body.

[0003] However, on traditional aluminum can production lines, sheet metal curling relies primarily on manual labor, resulting in low production efficiency and prone to errors, which can affect product quality. Therefore, there is an urgent need for an automated, intelligent sheet metal curling device to improve production efficiency and product quality.

[0020] Both sides of the bottom end of the movable plate 9 are fixedly connected with fixed plates 15 , and the bottom ends of the fixed plates 15 are in contact with the inclined surfaces of the inclined blocks 6 .

[0021] By adopting the above technical solution, through the cooperation between the fixed plate 15 and the inclined block 6, when the fixed plate 15 moves downward to contact the inclined block 6, continuing to move downward can push the two fixed plates 15 to move toward each other.

[0022] Both sides of the top of the movable plate 9 are fixedly connected with guide rods 16, and symmetrically distributed bearings 17 are fixedly installed on the L-shaped plate 7. The tops of the guide rods 16 are movable through the corresponding bearings 17.

[0023] By adopting the above technical solution, by setting the guide rod 16, it is convenient to guide the vertical movement of the movable plate 9, while increasing the stability of the structure, and by setting the bearing 17, it is convenient for the guide rod 16 to better slide vertically along the inside of the bearing 17.

[0024] A positioning groove 18 is formed at the top of each movable seat 4 , and an aluminum plate 19 is placed between the tops of the two positioning grooves 18 .

[0025] By adopting the above technical solution and providing the positioning groove 18 , it is convenient to position the aluminum plate 19 .

[0026] The sides of the movable seats 4 that are away from each other are fixedly connected with symmetrically distributed guide rods 20, and the ends of the guide rods 20 that are away from the movable seats 4 are movable through the U-shaped seat 2 and fixedly connected with fixed blocks.

[0032] Working principle: When curling the metal sheet of the aluminum can, the aluminum sheet 19 is placed between the inside of the two positioning grooves 18, and the positioning grooves 18 are used to position the metal sheet. Then, the movable plate 9 and the mold rod 12 are pushed downward by the extension of the piston rod of the hydraulic cylinder 8. When the mold rod 12 moves downward until it contacts the top surface of the aluminum sheet 19, it continues to move downward, and the elastic force of the spring 13 is used to deform the aluminum sheet 19, and cooperate with the semi-arc groove 3 to shape the lower half of the aluminum sheet 19. When the mold rod 12 moves to the bottom end of the semi-arc groove 3, the movable plate 9 continues to move downward. At this time, the fixed plate 15 and the inclined block 6 are in contact, and the two inclined blocks 6 are pushed to move toward each other. The cooperation between the quarter-arc groove 5 and the aluminum sheet 19 is used to shape the upper half of the aluminum sheet 19, thereby forming the cylindrical body of the aluminum can.

[0033] Then, as the piston rod of the hydraulic cylinder 8 contracts, the elastic force of the spring 21 and the spring 13 is used to reset the movable seat 4 and the mold rod 12 respectively, and the operation is repeated to achieve continuous curling operation of the aluminum can metal plate.
