Description

Technical Field

[0001] This invention relates to the field of aluminum alloy sheet processing technology, and more specifically to an automatic punching and extrusion device for aluminum alloy sheets. Background Technology

[0002] Aluminum alloy sheets are mostly formed using hot extrusion processes. During processing, after the aluminum rod is extruded at high temperatures, solidified aluminum and oxidized residue are easily left in the die cavity. If not cleaned in time, this can easily cause die cavity blockage and wear on the forming surface, leading to quality problems such as warping, dimensional deviations, and surface defects in subsequent aluminum alloy sheet forming. Therefore, regular die replacement, residue cleaning, and preheating regeneration are indispensable key processes in continuous aluminum alloy extrusion production.

[0003] Currently, traditional aluminum alloy stamping and extrusion equipment has a low level of automation. Die disassembly and assembly, residual material cleaning, die preheating, and reassembly largely rely on manual assistance. Traditional equipment lacks a dedicated automated die disassembly structure. The die and sleeve are tightly assembled, leading to numerous interferences during disassembly and assembly. Manual disassembly of the extrusion die often involves the use of tools, which can easily cause damage to the die and result in time-consuming die replacements. Furthermore, after disassembly, personnel need to spend considerable time cleaning the residual material remaining inside the die. Due to the drop in temperature after disassembly, there is a lack of temperature softening treatment for residual material, making die cleaning difficult and incomplete. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical problems in the background section, the following automatic punching and extrusion device for aluminum alloy sheets is provided: Combination Figures 1-12 As shown, the automatic punching and extrusion device for aluminum alloy sheet provided by the present invention includes: an aluminum rod extrusion mechanism 100, which includes a translational die base 101. An inner slot 102 is provided on the top of the translational die base 101. A front sleeve 103 and a constraint sleeve 104 are sequentially arranged inside the inner slot 102 along the extrusion direction. An extrusion die 200 is embedded inside the constraint sleeve 104. The heating assembly 300 includes a furnace body 301, inside which a storage bin 302 is inserted. Inside the storage bin 302, a first chamber 303 and a second chamber 304 are arranged in parallel. Inside the first chamber 303, an extrusion die 200 with built-in residual material is stacked to heat the residual material and the extrusion die 200 simultaneously, which facilitates subsequent cleaning of the residual material. Inside the second chamber 304, aluminum rods are stacked. The bottom surface of the first chamber 303 is a sloping structure with a higher inner surface and a lower outer surface. A discharge port 305 is opened at the outer end of the first chamber 303. The mold transfer mechanism 400 includes a hanging rail 401, a translational lifting assembly 402 slidably mounted on the bottom of the hanging rail 401, a loading assembly 403 slidably mounted on one end of the bottom of the translational lifting assembly 402, and a cutting assembly 404 slidably mounted on the other end of the bottom. The cutting component 404 is used to extend into the front sleeve 103 to cut off the excess material inside the extrusion die 200, so that the extrusion die 200 can be independently removed from the translation die base 101. The loading assembly 403 includes a first position adjusting component 404. The bottom end of the first position adjusting component 404 is provided with a docking component 405 and an ejection component 406. The docking component 405 is used to dock with the constraint sleeve 104, and the ejection component 406 is used to eject the extrusion die 200 from the constraint sleeve 104 to the inner end of the first chamber 303. The feeding temporary storage assembly 500 includes a base 501, a temporary storage seat 502 on the top of the base 501, the temporary storage seat 502 is located at the bottom of the discharge port 305 of the extended storage bin 302, a cleaning and pushing component 503 is installed on one side of the temporary storage seat 502, a stop component 504 with a flip structure is installed on the other side of the temporary storage seat 502, and a cavity straightening component 505 is installed at the bottom inside the temporary storage seat 502. The cavity straightening component 505 is used to adjust the cavity orientation of the extrusion die 200 that has fallen into the temporary storage seat 502 to the loading state; The cleaning and pushing component 503 is used to first clean the residual material of the extrusion die 200, and then push the extrusion die 200 into the constraint sleeve 104 carried by the docking component 405; The stop component 504 is used to stop the extrusion die 200 when the cleaning pusher component 503 is performing cleaning operations, and is retracted when the pusher is performing push operations.

[0021] In the above scheme: The storage silo 302 has a dual-chamber partitioned coupling structure with a first chamber 303 and a second chamber 304, which enables independent preheating of the mold and aluminum rod in separate zones. The two heating processes do not interfere with each other, effectively integrating the production process and reducing the production cycle.

[0022] The first chamber 303 adopts an inner high and outer low inclined surface structure to form a linkage with the discharge port 305, which can realize the orderly stacking and uniform heating of the extrusion die 200 with residual material, and simultaneously complete the heating and softening of the die body and cavity residual material. Meanwhile, relying on the self-weight sliding characteristics of the inclined plane, the mold can be automatically and orderly unloaded without the need for an additional drive structure. Combined with the receiving and guiding structure of the material support plate 600 under the furnace body 301, a continuous process system of heating and softening, self-weight sliding, and smooth transition unloading is formed.

[0023] The first position adjustment component 404 and the second position adjustment component adopt the same guide rail adjustment structure, which corresponds to loading and cutting operations respectively, to achieve precise vertical and horizontal multi-dimensional adjustment. This allows the two sets of operating mechanisms to be independently and accurately aligned without interfering with each other, thereby improving the overall machine's adaptability and alignment accuracy.

[0024] The second position adjustment component drives the hydraulic shears 445 to extend into the front sleeve 103. By driving the main shaft 444, the angle is adaptively adjusted to adapt to different postures of the protruding excess material, completely remove the redundant material at the outer end of the mold, and remove the wrapping interference of the front sleeve 103, providing the pre-obstacle clearing conditions for the mold to be released independently.

[0025] The threaded post 452 of the docking component 405 forms a rigid locking fit with the threaded hole of the constraint sleeve 104 to achieve a gapless fixed positioning; the second telescopic cylinder 461, push plate 462, and push head 463 of the matching push-out component 406 form a stable axial pushing structure, and the mold is evenly stressed and smoothly pushed out by relying on the locking positioning reference.

[0026] The detection camera 553, active straightening roller 551, and driven straightening roller 552 form a closed-loop linkage structure for visual detection and mechanical correction. This structure can identify mold cavity posture deviations in real time, automatically complete angle alignment and correction, unify mold loading benchmarks, and completely solve the problems of scattered postures and inconsistent cavity orientations after mold unloading. This provides posture assurance for subsequent accurate material cleaning and reassembly.

[0027] The cavity mating part 534 is precisely adapted to the mold cavity structure. Relying on the stable axial driving force of the third telescopic cylinder 532, it performs overall extrusion cleaning of the heated and softened cavity residue. It can thoroughly remove residual waste in the dead corners of the cavity, realize the regeneration of the mold cavity, and avoid subsequent stamping and forming defects caused by residual material scaling.

[0028] In this embodiment, the translational hoisting assembly 402 includes a hoisting frame 421, a hoisting seat 422, and a lateral translation component 423. The hoisting frame 421 is slidably installed on the bottom of the hoisting rail 401, and the hoisting seat 422 is fixedly installed on the bottom of the hoisting frame 421. The lateral translation component 423 is assembled on both sides of the hoisting seat 422. The lateral translation component 423 includes a lateral translation plate 424 and a first telescopic cylinder 425. The lateral translation plate 424 is slidably mounted on both sides of the bottom of the lifting base 422, and the first telescopic cylinder 425 connected to the lateral translation plate 424 is mounted on both sides of the lifting base 422. Overall sliding positioning is achieved through the lifting frame 421 and the lifting base 422. The independent sliding of the lateral translation plate 424 is driven by the first telescopic cylinder 425 of the two lateral translation components 423, enabling adaptive lateral fine-tuning of the dual-sided working mechanism. This effectively adapts to the installation position deviations of the mold and sleeve, ensuring accurate alignment of the cutting component 404 and the loading component 403.

[0029] In this embodiment, the first position adjustment component 404 includes a vertical plate 441, an active guide rail 442, and an L-shaped mounting plate 443. The vertical plate 441 is fixedly mounted on the end of the transverse translation plate 424, and the active guide rail 442 is fixedly mounted on the inner side of the vertical plate 441. The L-shaped mounting plate 443 is slidably mounted on the active guide rail 442. The docking component 405 and the ejection component 406 are mounted on the L-shaped mounting plate 443. By fixing the active guide rail 442 to the vertical plate 441, the L-shaped mounting plate 443 is driven to slide vertically and adjust, achieving adaptive alignment of the height of the docking component 405 and the ejection component 406. This can accurately match the vertical working position of the constraint sleeve 104 and the extrusion die 200, ensuring the coaxiality of the sleeve docking and the smoothness of the ejection action.

[0030] In this embodiment, the cutting component 404 includes a second position adjustment component 471 and a cutting component 472. The cutting component 472 is located at the bottom end of the second position adjustment component 471. The cutting component 472 is used to extend into the front sleeve 103 to cut off the excess material extending into the extrusion die 200. The second position adjustment component 471 adopts the same principle as the first position adjustment component 404. The cutting component 472 includes a mounting ear 473, a drive spindle 474, and a hydraulic shear 475. The mounting ear 473 is fixedly installed at the bottom of the second position adjustment component 471. The drive spindle 474 is rotatably installed inside the mounting ear 473. The hydraulic shear 475 is fixedly installed on the drive spindle 474. The second position adjustment component can realize multi-dimensional position adaptation adjustment. In conjunction with the mounting ear 473 and the drive spindle 474, it drives the hydraulic shear 475 to rotate and adjust the angle, which can adaptively adapt to the excess material in different postures. The hydraulic shears 445 can be precisely inserted into the front sleeve 103 to completely remove the excess material from all directions, thus eliminating the structural interference of the front sleeve 103 on mold disassembly and providing a reliable structural guarantee for the independent and jam-free removal of the mold.

[0031] In this embodiment, the docking component 405 includes a drive motor 451 and a threaded post 452. The drive motor 451 is fixedly mounted on the top of the L-shaped mounting plate 443. The output shaft of the drive motor 451 passes through the L-shaped mounting plate 443 and is connected to the threaded post 452 via a coupling. The threaded post 452 is used to thread-connect the constraint sleeve 104. The top of the constraint sleeve 104 is provided with a threaded hole for connecting the threaded post 452. The drive motor 451 drives the threaded post 452 to rotate, forming a rigid threaded connection and fixation with the threaded hole at the top of the constraint sleeve 104. This achieves gapless locking and positioning between the loading component 403 and the constraint sleeve 104, avoiding sleeve shaking and displacement during the material pushing operation.

[0032] In this embodiment, the ejection component 406 includes a second telescopic cylinder 461, a push plate 462, and an ejection head 463. The second telescopic cylinder 461 is fixedly installed at the bottom of the L-shaped mounting plate 443, and the push plate 462 is installed at the output end of the second telescopic cylinder 461. The top of the push plate 462 is slidably connected to the L-shaped mounting plate 443, and the ejection head 463 is fixedly installed on one side of the push plate 462. The push plate 462, through the ejection head 463, is used to eject the extrusion die 200 inside the constraint sleeve 104. The second telescopic cylinder 461 drives the push plate 462 to slide smoothly along the L-shaped mounting plate 443, driving the ejection head 463 to push the extrusion die 200. Relying on the sliding guide structure to ensure a smooth ejection stroke and uniform axial force, the extrusion die 200 can be ejected smoothly and as a whole from inside the constraint sleeve 104.

[0033] In this embodiment, the cleaning and pushing component 503 includes a support base 531, a third telescopic cylinder 532, a mounting base 533, and a cavity docking component 534. The support base 531 is fixedly mounted on a base 501 on one side of the temporary storage seat 502. The third telescopic cylinder 532 is fixedly mounted on the support base 531. The mounting base 533 is fixedly mounted on the output end of the third telescopic cylinder 532, and the cavity docking component 534 is fixedly mounted on the side of the mounting base 533 corresponding to the temporary storage seat 502. The cavity docking component 534 is used to push out residual material from the cavity of the mold 200. The support base 531 fixes the third telescopic cylinder 532, driving the mounting base 533 and the cavity docking component 534 to align with the mold cavity. This allows for axial overall extrusion cleaning of residual material in the cavity after the furnace body has been heated and softened, adapting to the cavity structure, thoroughly removing residual material from dead corners, and achieving complete regeneration of the mold cavity.

[0034] In this embodiment, the stop component 504 includes a flipping frame 541, a receiving box 542, and right-angle abutment rods 543. The flipping frame 541 is fixedly installed on the side of the temporary storage box away from the mounting base 533. The receiving box 542, which can be actively flipped, is rotatably installed inside the flipping frame 541. Right-angle abutment rods 543 are fixedly installed on both sides of the top of the receiving box 542. The ends of the right-angle abutment rods 543 are used to abut against the outer surface of the extrusion mold 200. The flipping frame 541 drives the receiving box 542 to actively flip and switch positions. During the material clearing operation, the right-angle abutment rods 543 on both sides of the receiving box 542 rigidly abut against the outer wall of the mold to achieve stable mold positioning, avoid deviation and shaking during the material pushing process, and ensure the alignment accuracy of the material clearing. During the mold pushing and reloading process, it automatically flips to avoid interference.

[0035] In this embodiment, the cavity straightening component 505 includes an active straightening roller 551, a driven straightening roller 552, and a detection camera 553. The active straightening roller 551 is rotatably mounted inside the temporary storage seat 502, and the driven straightening rollers 552 are rotatably mounted above both sides of the active straightening roller 551. The detection camera 553 is built into the support seat 531 above the cavity docking part 534, and the imaging surface of the detection camera 553 corresponds to the extrusion mold 200 inside the temporary storage seat 502. The detection camera 553 collects the mold posture data inside the temporary storage seat 502 in real time, and coordinates with the active straightening roller 551 and the driven straightening roller 552 to automatically complete the mold angle fine adjustment and posture alignment; it can unify the cavity operation position of all molds and accurately straighten the mold to the standard loading state.

[0036] In this embodiment, a material support plate 600 is fixedly installed on the furnace body 301 below the storage silo 302, and the end of the material support plate 600 is connected to the top of the temporary storage seat 502. The path of the material support plate 600 is consistent with that of the second chamber 304. The material support plate 600 is used to support the extrusion die 200 at the discharge port 305. The end of the material support plate 600 is fixedly connected to the temporary storage seat 502 and is consistent with the discharge path of the second chamber 304. It can stably support the extrusion die 200 output from the discharge port 305, realize the smooth transition and transfer of the die, avoid the die falling, shifting, or misalignment, and ensure seamless connection between the heating and discharging station and the temporary storage and correction station.

[0037] Working principle and usage process of this invention: Step 1: During normal operation, the translational die base 101 of the aluminum rod extrusion mechanism 100 is limited and assembled with the front sleeve 103 and the constraint sleeve 104 through the top inner slot 102. The extrusion die 200 is stably embedded inside the constraint sleeve 104 to complete the conventional stamping and forming operation of aluminum alloy rods. When a single batch of stamping process is completed, there is residual cooling material inside the die, and it is necessary to replace the die or clean the residual material, the equipment automatically stops the stamping feed and enters the automatic die replacement, cleaning, and heating pretreatment mode. At this time, the die transfer mechanism 400, heating component 300, and feeding temporary storage component 500 have all completed the origin reset and are in standby mode. All adjustment components, telescopic components, and correction components are in the initial standby state, providing the structural foundation for the fully automatic die changing process.

[0038] Step Two: The mold transfer mechanism 400 initiates a pre-clearing operation. The lifting frame 421 at the bottom of the hanging rail 401 slides along the rail body for alignment, driving the lifting seat 422 to move as a whole above the aluminum rod extrusion mechanism 100. Relying on the first telescopic cylinder 425 of the lateral translation component 423, the lateral translation plate 424 is driven to slide precisely, achieving lateral alignment adjustment of the double-sided structure. The second position adjustment component on one side of the lifting seat 422 drives the cutting component 404 to precisely descend for alignment. The second position adjustment component adopts a vertical guide rail adjustment structure adapted to the first position adjustment component, enabling precise fine-tuning of the cutting height and horizontal position.

[0039] After alignment, the drive spindle 444 of the cutting component 404 drives the hydraulic shears 445 to rotate and adjust their angle, allowing the hydraulic shears 445 to precisely extend into the front sleeve 103 and cut off the residual material extending outward from the extrusion die 200. This step can completely remove the redundant material at the outer end of the die, release the front sleeve 103 from the enclosing and limiting interference of the extrusion die 200, and allow the subsequent extrusion die 200 to independently and without jamming detach from the constraint sleeve 104, providing the pre-construction structural conditions for the overall removal and separation of the die.

[0040] Step 3: After the excess material is removed, the mold transfer mechanism 400 switches to a different work station. The first position adjustment component 404 on the other side of the lifting base 422 starts the alignment adjustment. The vertical plate 441 and the active guide rail 442 drive the L-shaped mounting plate 443 to slide vertically and precisely. With the help of the laser positioner 444, the docking component 405 and the ejection component 406 are precisely aligned in height. The drive motor 451 of the docking component 405 drives the threaded column 452 to rotate, so that the threaded column 452 and the threaded hole at the top of the constraint sleeve 104 are threaded and locked together. This achieves rigid fixation of the docking component 405 and the constraint sleeve 104, ensuring that there is no offset or shaking during the subsequent material ejection process.

[0041] After the sleeve is locked in place, the ejector component 406 starts operation. The second telescopic cylinder 461 drives the push plate 462 to slide smoothly along the L-shaped mounting plate 443, which in turn drives the ejector head 463 to precisely push the extrusion die 200 inside the constraint sleeve 104, so that the extrusion die 200 is completely removed from the insertion limit of the constraint sleeve 104, realizing the automatic separation of the die and the sleeve and independent discharge, thus completing the automated disassembly process of the extrusion die 200.

[0042] Step Four: The extrusion die 200 is smoothly transferred by the die transfer mechanism 400 and precisely moved into the furnace body 301 of the heating component 300, where it is orderly stacked inside the first chamber 303 of the storage bin 302. The storage bin 302 adopts a dual-chamber independent partition structure. The first chamber 303 is specifically used to stack the extrusion die 200 with residual material inside, which can simultaneously and constant-temperature heat the die body and the residual material in the cavity. The second chamber 304 independently stacks the aluminum rods to be extruded, realizing the synchronous preheating of the die and raw materials in separate areas without interference.

[0043] The first chamber 303 adopts an inclined structure with a higher inner surface and a lower outer surface, which ensures that the stacked extrusion die 200 always maintains a regular orientation, providing structural conditions for subsequent gravity sliding and automatic feeding. At the same time, it ensures that the die is heated evenly and the residual material is fully softened during the furnace heating process, providing a temperature basis for subsequent high-temperature residual material extrusion and cleaning.

[0044] Step 5: After the mold and the remaining material inside have been heated to a constant temperature in the furnace and the remaining material has been fully softened, the extrusion mold 200 in the first chamber 303 slides autonomously along the inclined structure and is discharged out through the outer end discharge port 305. The material support plate 600 fixed below the furnace body 301 receives the mold output from the discharge port 305 and smoothly lifts and transports it along the corresponding path in the second chamber 304, so that the extrusion mold 200 falls accurately into the temporary storage seat 502 of the feeding temporary storage component 500.

[0045] After the mold falls into the temporary storage seat 502, the cavity correction component 505 initiates the posture correction operation. The detection camera 553 collects the orientation and posture data of the mold cavity in real time. The active correction roller 551, together with the driven correction rollers 552 on both sides, rotates synchronously to fine-tune the angle and straighten the posture of the mold, uniformly correcting the orientation of the cavity of the extrusion mold 200 to the standard loading state, ensuring accurate alignment for subsequent residual material extrusion and mold reinstallation. At the same time, the stop component 504 is in a vertical contact position, and the flipping frame 541 supports the receiving box 542 to remain upright. The right-angle contact rods 543 on both sides contact the outer surface of the mold to limit and fix the mold, preventing the mold from shifting or shaking during the cleaning and pushing process.

[0046] Step Six: After the mold posture correction and limit fixation are completed, the cleaning and pushing component 503 starts the cleaning operation. The third telescopic cylinder 532 on the top of the support base 531 extends and retracts, driving the mounting base 533 and the front cavity docking part 534 to precisely push into the cavity of the extrusion mold 200, and axially forcefully extruding the residual material inside the cavity after the furnace body has been heated and softened. Through mechanical rigid pushing, the high-temperature residual material attached to and remaining inside the mold is completely extruded, thoroughly cleaning the dead corners of the mold cavity and achieving complete cleaning and regeneration of the cavity of the extrusion mold 200.

[0047] After the single-wheel material clearing operation is completed, the stop component 504 automatically flips and retracts, releasing the lateral limit of the mold and making room for subsequent mold reset and sleeve reinstallation.

[0048] Step Seven: After the clean extrusion die 200 has been cleaned of excess material, it is pushed a second time by the cleaning and pushing component 503 into the constraint sleeve 104 fixed by the docking component 405, completing the reset assembly of the die and the sleeve. Subsequently, the die transfer mechanism 400 resets as a whole, reinstalling the assembled sleeve and die into the inner slot 102 of the translation die base 101. The equipment returns to the standard stamping station and can directly start the next round of aluminum alloy sheet stamping processing. The entire process of die replacement, heating, cleaning, and reinstallation is completed automatically in a closed loop.
