[0002] Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. In the process of processing aluminum alloy, it is often necessary to use a punching device to punch the aluminum alloy, such as the punching device for aluminum alloy profile processing proposed by the application number "CN202020468972.4", which includes a workbench, and the four corners of the bottom of the workbench are fixedly connected to support legs, and the lower end of the workbench is fixedly connected to a drive motor, and the upper end output shaft of the drive motor passes through the surface of the workbench and is fixedly connected to a rotating plate, and the surface of the rotating plate is evenly installed with a plurality of clamping mechanisms arranged in an annular distribution, and one side of the upper end of the workbench is fixedly connected to a punching machine corresponding to the position of the clamping mechanism. The utility model can realize non-stop loading and unloading operations, greatly improves the punching efficiency, and is easy to use;

[0003] However, in the above technical solution, although aluminum alloy can be punched, only a single-angle punching method from top to bottom is adopted, which results in that when punching is required on multiple surfaces or angles of the raw material, it is often necessary to adjust the position of the raw material multiple times. However, this method not only increases the complexity of operation, but also reduces the overall processing efficiency, and it is difficult to ensure the processing accuracy and consistency of each hole position, affecting the overall quality of the product.

[0038] The forward and reverse screw rods 204 are controlled to rotate by the No. 2 motor 208, so that the forward and reverse screw rods 204 can move in relative or opposite directions through the threaded control slider 203 to adjust the distance between the rollers 207 according to the width of the raw material, so that the rollers 207 can fit tightly with the raw material, and then the No. 1 motor 206 drives the rollers 207 to rotate, so that the rollers 207 can control the raw material for feeding, and also clamp and position the raw material, thereby reducing the user's work difficulty and improving the stability of the raw material during the punching process.

[0039] like Fig.13 and Fig.14 As shown, annular limit frames 412 are respectively installed on the side away from each other of the No. 1 annular frame 404 and the No. 2 annular frame 405, annular limit grooves 413 are respectively provided on both sides of the interior of the No. 1 groove 402, and the annular limit frames 412 are respectively snap-fitted and installed inside the annular limit grooves 413, and electric slip rings 415 are respectively installed on the side away from each other of the No. 1 annular frame 404 and the No. 2 annular frame 405, annular guide grooves 414 are respectively provided on both sides of the interior of the No. 1 groove 402, and the electric slip rings 415 are respectively movably installed inside the annular guide grooves 414, and brushes 416 are respectively installed on the upper ends of the inner parts of the annular guide grooves 414, and the brushes 416 are connected to the electric slip rings 415.

[0040] The annular limiting frame 412 and the annular limiting groove 413 are used to assist the first annular frame 404 and the second annular frame 405 to rotate, thereby improving the stability of the first annular frame 404 and the second annular frame 405 during rotation, and preventing the first annular frame 404 and the second annular frame 405 from falling or tilting, making them more stable;

[0041] Then, the electric slip ring 415 and the brush 416 are used to replace the wires to supply power to the whole, thereby avoiding the situation where the wires are entangled during the rotation of the first ring frame 404 and the second ring frame 405 when powering various electrical appliances through the wires, thereby improving the overall safety performance.

[0042] like Fig.13 and Fig.14 As shown, a movable groove 410 is provided inside the No. 1 annular frame 404 and the No. 2 annular frame 405 respectively, and a sealing cover 411 is installed on the side where the No. 1 annular frame 404 and the No. 2 annular frame 405 are close to each other through bolts, and the sealing cover 411 is used to seal and protect the interior of the movable groove 410, and an annular movable block 417 is movably installed inside the movable groove 410, and an annular limiting plate 418 is installed on both sides of the annular movable block 417, and the annular limiting plate 418 is clamped and installed between the movable groove 410 and the sealing cover 411.

[0043] The sealing cover 411 cooperates with the bolts to seal the interior of the No. 1 movable groove 410, and also facilitates the later user to open the sealing cover 411 to inspect and repair the various components inside the No. 1 movable groove 410, so as to improve the overall safety performance and stability performance;

[0044] At the same time, the sealing cover 411 is also used to engage the annular limiting plate 418, so that the annular limiting plate 418 can stably assist the annular movable block 417 to rotate, thereby improving the stability of the annular movable block 417 during rotation.

[0045] like Fig.10 and Fig.13 As shown, a turbine 419 is installed on one side of the annular movable block 417 away from the annular limiting plate 418, a fixed block 420 is installed on the inner upper end of the No. 1 movable groove 410, a placement groove 421 is provided on the inner lower end of the fixed block 420, a worm 422 is movably installed inside the placement groove 421, the worm 422 is meshingly connected with the turbine 419, a No. 3 motor 423 is installed inside the fixed block 420, and the output end of the No. 3 motor 423 is connected to the worm 422.

[0046] When it is necessary to control the annular movable block 417 to rotate, the third motor 423 can reach the worm 422 to rotate forward and backward, and then the worm 422 can cooperate with the turbine 419 to drive the annular movable block 417 to rotate forward and backward, so that the annular movable block 417 controls the first tooth 428 and the second tooth 448 to move, thereby realizing the engagement connection between the first annular frame 404 and the second annular frame 405, or the positioning of the first annular frame 404 and the second annular frame 405. At the same time, the self-locking performance between the worm 422 and the turbine 419 is used to further improve the stability of the annular movable block 417, so that the first annular frame 404 and the second annular frame 405 are more stable when connected or positioned.

[0047] like Fig.11 , Fig.14 , Fig.15 and Fig.16As shown, a plurality of No. 2 grooves 424 are respectively provided inside the No. 1 movable groove 410, and a connecting block 425 is movably installed inside the No. 2 groove 424. A No. 1 tooth 428 is respectively installed on the lower surface of the connecting block 425, and a No. 1 ring rack 429 is respectively installed at both ends of the No. 1 groove 402. Each No. 1 tooth 428 is respectively meshed and connected with the No. 1 ring rack 429. Positioning grooves 427 are respectively provided on the front and rear sides of the No. 2 groove 424, and positioning blocks 426 are respectively installed on the front and rear sides of the connecting block 425. The positioning blocks 426 are respectively snap-fitted and installed inside the positioning grooves 427. The upper end of the interior of the connecting block 425 is respectively provided with a No. 2 movable groove 430, and the No. 2 movable groove 430 A connecting frame 431 is movably installed through the interior of the connecting frame 431, a No. 1 spring 432 is respectively installed between the lower end of the connecting frame 431 and the No. 2 movable groove 430, a transmission plate 433 is fixedly installed on the upper end of the connecting frame 431, and the transmission plate 433 is movably located inside the No. 1 movable groove 410, an auxiliary groove 434 is penetrated inside the transmission plate 433, and a guide plate 436 is respectively engaged and installed inside the auxiliary groove 434, one end of the guide plate 436 is fixedly installed on the inner wall of the No. 1 movable groove 410, and No. 2 springs 435 are respectively installed between the auxiliary groove 434 and the guide plate 436, and a plurality of inclined plates 437 are respectively installed on the side away from each other of the annular movable block 417, and the inclined plate 437 is in contact with the transmission plate 433.

[0048] When the No. 1 annular frame 404 and the No. 2 annular frame 405 need to be positioned, the worm 422 and the turbine 419 drive the annular movable block 417 to rotate forward, so that the annular movable block 417 pushes the transmission plate 433 through the inclined surface of the inclined plate 437, so that the transmission plate 433 pushes the connecting frame 431 and the connecting block 425 to move outward, so that the connecting block 425 drives the No. 1 tooth 428 to be stuck in the interior of the No. 1 annular rack 429, so as to realize the positioning of the No. 1 annular frame 404 and the No. 2 annular frame 405, so that they can stably support the punch head 409 and the mold 407;

[0049] When the transmission plate 433 moves downward, the transmission plate 433 will squeeze the No. 2 spring 435 through the auxiliary groove 434 and the guide plate 436, so that when the annular movable block 417 drives the inclined plate 437 to reset, the No. 2 spring 435 can drive the transmission plate 433, the connecting frame 431 and the connecting block 425 to reset;

[0050] The guide plate 436 is used to cooperate with the auxiliary groove 434 to guide the transmission plate 433 to move straight up and down, ensuring that the transmission plate 433 does not tilt, so that it can stably drive the connecting block 425 and the first tooth 428 to move up and down;

[0051] The No. 1 spring 432 installed between the connecting frame 431 and the No. 2 movable groove 430 is used to buffer and extend the space between each connecting frame 431 and the No. 1 tooth 428, so that after one of the No. 1 teeth 428 is meshed with the No. 1 annular rack 429, the annular movable block 417 can still continue to rotate to control the other No. 1 teeth 428 to mesh with the No. 1 annular rack 429, so as to avoid the situation that after one of the No. 1 teeth 428 is meshed with the No. 1 annular rack 429, there is still a gap between the other No. 1 teeth 428 and the No. 1 annular rack 429, resulting in poor overall meshing stability, which is more convenient;

[0052] The positioning block 426 and the positioning groove 427 are used to assist the connecting block 425 and the first tooth 428 to move straight up and down, thereby improving the accuracy of the connecting block 425 during movement and preventing the occurrence of offset and tilt that may lead to a failure in engagement.

[0053] like Fig.13 and Fig.16 As shown, a ring-shaped placement groove 438 is provided on the surface of the sealing cover 411 located on the No. 2 annular frame 405, and a No. 2 annular rack 439 is installed inside the ring-shaped placement groove 438.

After the angle of the punch head 409 on the second ring frame 405 moves to the specified position, the third motor 423 drives the annular movable block 417 to rotate forward through the worm 422 and the turbine 419, so that the annular movable block 417 drives the inclined plate 437 to push the transmission plate 433, so that the transmission plate 433 drives the first tooth 428 to fit into the inside of the first ring rack 429 to realize the positioning of the second ring frame 405. Then the user places the raw material on the upper end of the support block 201. The No. 2 motor 208 controls the forward and reverse screw rods 204 to rotate, so that the forward and reverse screw rods 204 can move in relative or opposite directions through the threaded control slider 203 to adjust the spacing between the rollers 207 according to the width of the raw material, so that the rollers 207 can fit closely with the raw material, and then the No. 1 motor 206 drives the rollers 207 to rotate, so that the rollers 207 can control the raw material to load the material, and then after the raw material moves between the punching head 409 and the mold 407, the corresponding No. 1 electric-controlled hydraulic cylinder 406 and No. 2 electric-controlled hydraulic cylinder 408 can push the mold 407 and the punching head 409 to move, so that the punching head 409 can punch the raw material.
