Description
Technical Field
[0001] This utility model relates to the field of aluminum metal processing technology, specifically to an aluminum rolling and trimming device. Background Technology
[0002] Aluminum is a metallic element with the symbol Al and atomic number 13. It is a silvery-white, lightweight metal with excellent ductility and is commonly produced in various forms, including rods, plates, sheets, foils, powders, strips, and wires. In the production of aluminum sheets, aluminum blocks are repeatedly heated and rolled to a suitable thickness, and then trimmed to obtain the finished aluminum sheet. This process requires an aluminum rolling and trimming device. Existing aluminum rolling and trimming devices typically consist of a rolling unit and a trimming unit. The rolling unit has two adjustable-gap pressure rollers, while the trimming unit consists of clamps, a motor, and a cutting blade. During operation, the motor drives the two pressure rollers to rotate in opposite directions. The heated aluminum block moves along a roller conveyor line, and as it passes the two rotating pressure rollers, the rollers exert a squeezing effect on the aluminum block. The aluminum block repeatedly passes through the pressure rollers. Each time the aluminum block passes between two pressure rollers, the distance between the two rollers is gradually reduced until the aluminum block forms an aluminum sheet of suitable thickness. Then, the upper and lower drive devices drive the upper and lower clamping blocks to move inward synchronously, creating an upper and lower limit effect on the aluminum sheet. The front and rear drive devices drive the motor and cutting blade to move inward to the appropriate position. The motor drives the cutting blade to rotate at high speed, cutting off the edges of the aluminum sheet to form the finished aluminum sheet. Traditional aluminum rolling and trimming devices lack limits on the front and rear sides of the aluminum sheet during trimming, resulting in poor trimming accuracy. Furthermore, multiple drive devices are required to adjust the cutting position and limit the aluminum sheet, leading to troublesome and costly maintenance. Therefore, we propose an aluminum rolling and trimming device. Utility Model Content

A trimming mechanism 4 is provided, which can quickly limit the aluminum sheet in four directions (up, down, front, and back) with just one hydraulic cylinder 46, and can also simultaneously adjust the cutting edge position of the aluminum sheet, improving the trimming accuracy and reducing the equipment's operation and maintenance costs.
[0026] The working principle of the aluminum rolling and trimming device provided by this utility model is as follows: When performing aluminum sheet rolling and trimming, the heated aluminum block is repeatedly conveyed by the external roller conveyor line between the upper pressure roller 7 and the lower pressure roller 8. The microcontroller 13 drives two motors 10 to operate. The two motors 10 rotate in opposite directions. The upper pressure roller 7 rotates clockwise, and the lower pressure roller 8 rotates counterclockwise, which moves the aluminum block to the left and also creates a squeezing effect on the aluminum block. Before the aluminum block enters the rolling shell 5 each time, the external hydraulic pump station works, and the telescopic end of the hydraulic cylinder 9 moves downward by a certain distance. The distance between the upper pressure roller 7 and the lower pressure roller 8 also decreases accordingly. The thickness of the aluminum block also decreases each time it passes through, until the aluminum block is completely flattened. After the aluminum sheet of suitable thickness is formed, it enters the mounting frame 1 for trimming. First, adjust the limiting distance of the limiting wheel 447 and the cutting position of the cutting blade 446 according to the size of the aluminum sheet. Turning the knob drives the lead screw 443 to rotate, and the slider 442 moves inward. The number of rotations of two longitudinally adjacent knobs is the same, and the limiting wheel 447 and cutting blade 446 also move accordingly until both reach the appropriate position. The distance between the two sets of limiting wheels 447 is greater than the distance between the two cutting blades 446. The external hydraulic pump station operates, and the telescopic end of the hydraulic cylinder 46 moves downward, driving the upper moving plate 2 downward, and the rack plate 42 also moves downward. As rack plate 1 (42) moves, gear 41 rotates, causing rack plate 2 (43) to move upwards, and the lower moving plate 2 also moves upwards. At this time, both moving plates 2 move inwards synchronously, and the dustproof sheet 12 folds downwards until the outer edge of the clamping wheel 3 contacts the surface of the aluminum plate. The rotatable clamping wheel 3 can both limit the vertical movement of the aluminum plate without obstructing its horizontal movement. Simultaneously, as gear 41 rotates, rack plate 3 (441) moves inwards, causing the limiting wheel 447 and cutting blade 446 to move inwards synchronously. The limiting wheel 447 first contacts the surface of the aluminum plate, providing front and rear limiting. As the aluminum plate continues to move, the microcontroller 13 controls the electrical... When motor 445 operates, it drives the cutting blade 446 to rotate at high speed through the acceleration of gearbox 444. When the aluminum sheet passes through the high-speed rotating cutting blade 446, the high-speed rotating cutting blade 446 cuts off the edge of the aluminum sheet, making the edge of the aluminum sheet neat. As the aluminum sheet continues to move, microcontroller 13 controls motor 453 to operate. Motor 453 drives grinding disc 452 to rotate at high speed. When the aluminum sheet passes through grinding disc 452, the high-speed rotating grinding disc 452 grinds away the burrs produced by the cutting blade 446, realizing the trimming work of the aluminum sheet. During this process, dust plate 11 and dust sheet 12 can prevent the debris generated during trimming from falling on the surface of the equipment and affecting the operation of the equipment.
[0027] It is worth noting that the microcontroller 13 disclosed in the above embodiments is an SC8F2892B microcontroller, motor 1 445 is a DKM motor, motor 2 453 is a 2BLD10-24GN-20S motor, and motor 3 10 is a YE3-180M-2 motor. The microcontroller 13 controls the operation of motor 1 445, motor 2 453 and motor 3 10 using methods commonly used in the prior art.
