[0037] Please refer to Figures 1-6As shown, this utility model provides a technical solution for a circular cutting machine for aluminum sheet processing: A circular cutting machine for aluminum sheet processing includes a mounting box 1. A mounting frame 2 is fixedly installed on one side of the upper surface of the mounting box 1. A sliding frame 3 is slidably connected to one side of the mounting box 1 through a mounting groove. The sliding frame 3 moves horizontally within the mounting groove. A cutting mechanism 4 is installed on the mounting box 1 and the sliding frame 3. A feed assembly 5 for controlling the feed of the cutting mechanism 4 is also installed on the sliding frame 3. The cutting mechanism 4 includes a central clamping rod 401, a drive motor 402, and a telescopic rod 404. The central clamping rod 401 is symmetrically installed on adjacent sides of the mounting box 1 and the mounting frame 2 and is coaxial with the mounting box 1. The end of the central clamping rod 401 is a rotating structure, and the upper end of the central clamping rod 401, through telescopic extension, cooperates with the lower end of the central clamping rod 401 to clamp the aluminum sheet at a preset center. The clamped aluminum sheet can rotate around the axis of the central clamping rod 401. The drive motor 402 is fixedly mounted on the upper end of one side of the sliding frame 3. The output end of the drive motor 402 is connected to a drive wheel 403 for driving the aluminum sheet to rotate. The telescopic rod 404 is movably mounted on the end of the mounting frame 2 above the drive wheel 403. The lower end of the telescopic rod 404 is rotatably connected to a pressure wheel 405. The telescopic rod 404 is electrically telescopic to provide downward pressure to the pressure wheel 405, ensuring that the aluminum sheet is tightly pressed between the pressure wheel 405 and the drive wheel 403.

[0038] When it is necessary to trim and round the aluminum sheet, first adjust the position of the sliding frame 3 according to the required diameter of the aluminum sheet. Then, preset and mark the center position after the rounding is completed, and place the center of the aluminum sheet on the lower center clamping rod 401, controlling the upper end of the center clamping rod 401 to extend and clamp. At this time, the aluminum sheet can rotate around the axis of the center clamping rod 401. At the same time, the telescopic rod 404 drives the pressure wheel 405 to move downward until the edge of the aluminum sheet is pressed between the pressure wheel 405 and the drive wheel 403. Then, start the drive motor 402, and the drive wheel 403 will start to rotate, and the aluminum sheet will start to rotate around the axis of the center clamping rod 401. At this time, the operator can control the feed assembly 5 to feed and cut the edge of the aluminum sheet. The feed depth determines the diameter of the aluminum sheet. When the feed reaches the specified depth, the processing is completed.

[0039] The edge trimming mechanism 4 enables rapid and precise trimming of the edge of a single aluminum sheet or adjustment of the diameter of a circular sheet. Positioning is simple, the cutting process is controllable, and even thinner aluminum materials can ensure the accuracy of positioning and feeding. This simplifies the process of trimming and rounding aluminum sheets, improves the success rate and efficiency of trimming and rounding a single aluminum sheet, and the rolling friction feeding by the rollers will not damage the surface of the aluminum sheet, further ensuring the quality of the finished product.

[0040] The feeding assembly 5 comprises a sliding plate 501, a feeding spring 504 and a trigger assembly 506. The sliding plate 501 is slidingly connected in a sliding groove on the sliding frame 3, and the upper end of the sliding plate 501 is fixedly installed with a tool holder 502, and the upper end of the tool holder 502 is installed with a cutting knife 503 for cutting aluminum sheets. The feeding spring 504 is installed on the inner side of the sliding frame 3 for pushing the tool holder 502 to feed, and the side of the sliding frame 3 away from the feeding spring 504 is fixedly installed with a damping rod 505, the end of the damping rod 505 is in contact with the tool holder 502, and the contraction amount of the damping rod 505 is constant. The trigger assembly 506 is installed on one side of the sliding frame 3 for limiting the sliding plate 501,

[0041] The trigger assembly 506 comprises a top block 5061 and a control rope 5063. The top block 5061 is slidingly connected in a mounting hole at the lower end of the sliding frame 3, and the upper end of the top block 5061 is provided with an inclined edge matched with the chamfer at the end of the sliding plate 501, when the feeding spring 504 is in the contraction state, the upper end of the top block 5061 is placed in the groove at the end of the sliding plate 501, and the sliding plate 501 is stabilized to avoid displacement. A reset spring 5062 for pushing the top block 5061 to reset is also installed in the mounting hole at the lower end of the sliding frame 3. The control rope 5063 is movably installed in a rope groove on one side of the sliding frame 3, one end of the control rope 5063 is located outside the sliding frame 3, and the other end of the control rope 5063 is connected with the lower end of the top block 5061.

[0042] When it is necessary to cut the aluminum sheet, the worker pulls the control rope 5063 against the elastic force of the reset spring 5062, the control rope 5063 drives the top block 5061 to move downward to release the sliding plate 501, at this time, the tool holder 502, the cutting knife 503 and the sliding plate 501 begin to slowly move to the driving wheel 403 direction against the resistance of the damping rod 505 under the pushing force of the feeding spring 504, and the edge of the aluminum sheet is cut during the feeding process, when the damping rod 505 is completed, the cutting knife 503 is fed to the specified depth, at this time, the aluminum disc has been processed to the preset diameter. At this time, the aluminum disc can be removed and the tool holder 502 and the cutting knife 503 are reset, the tool holder 502 is pulled back by hand against the elastic force of the feeding spring 504, when the end of the sliding plate 501 is repositioned by the top block 5061, the reset is completed.

[0043] Through the feeding assembly 5, the damping rod 505 and the feeding spring 504 are matched to realize the effect of slow feeding, the feeding process is stable, the edge cutting quality is further improved, and the trigger control is convenient and the operation convenience is high.

[0044] Since the contraction amount of the damping rod 505 is constant, it is necessary to adjust the position of the sliding frame 3 before starting cutting, and the distance from the end of the cutting knife 503 to the center of the center clamping rod 401 is the radius of the aluminum disc after the damping rod 505 is contracted.

[0045] The lower end of the slide plate 501 is provided with a pulley for reducing friction, which can improve the smoothness of the slide plate 501 moving in the sliding groove of the sliding frame 3.

[0046] The end of the control rope 5063 is provided with a pull ring 5064, which is convenient for workers to grasp and pull the control.

[0047] The two ends of the sliding frame 3 are provided with positioning members 301, which can be a combination of electromagnets and permanent magnets, the electromagnets generate repulsion or attraction force through current control, thereby driving the permanent magnets to stretch or retract at the two ends of the sliding frame 3, and finally realizing the effect of positioning the sliding frame 3 in the mounting groove of the mounting box 1.

[0048] The horizontal distance between the cutter 503 and the driving wheel 403 is 5 mm in the retracted state of the damping rod 505, and when the distance is greater than 5 mm, the thin aluminum sheet may be curled during cutting, which is difficult to control.

[0049] The upper end surface of the mounting box 1 is provided with an auxiliary table 6 for lifting the aluminum sheet, which can ensure the overall flatness of the aluminum sheet during processing.

[0050] The working principle of the utility model is as follows:

[0051] When the circular cutting machine for aluminum sheet processing of the embodiment is used, if it is necessary to cut and edge the aluminum sheet, first, the position of the sliding frame 3 is adjusted according to the diameter of the required aluminum circular sheet, and the positioning member 301 is started to position the sliding frame 3 in the mounting groove of the mounting box 1. Then, the center position of the circular sheet after cutting is preset and marked, and the center of the aluminum sheet is placed on the lower center clamp rod 401, and the upper center clamp rod 401 is controlled to extend the end to complete clamping. At this time, the aluminum sheet can rotate with the axis of the center clamp rod 401 as the center. At the same time, the telescopic rod 404 drives the pressing wheel 405 to move downward until the edge of the aluminum sheet is pressed between the pressing wheel 405 and the driving wheel 403. Then, the driving motor 402 is started, and the driving wheel 403 starts to rotate immediately, and the aluminum sheet starts to rotate with the center clamp rod 401 as the axis. At this time, the worker can control the start of the tool, first overcomes the elastic force of the return spring 5062 to pull the control rope 5063, the control rope 5063 drives the top block 5061 to move downward to release the slide plate 501, at this time, under the pushing force of the feeding spring 504, the tool holder 502, the cutter 503 and the slide plate 501 start to slowly move to the driving wheel 403 direction to feed under the resistance of the damping rod 505, and the edge of the aluminum sheet is cut during the feeding process, when the damping rod 505 is retracted, the cutter 503 is fed to the specified depth, at this time, the aluminum circular sheet has been processed to the preset diameter. At this time, the aluminum circular sheet can be taken out. The slide plate 501, the tool holder 502 and the cutter 503 are reset to facilitate the processing of the next aluminum sheet.

[0052] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
