Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and specifically to a rotary aluminum profile stamping die for automotive parts manufacturing. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the vehicle. There are many types of automotive parts, and as people's living standards improve, their car consumption is increasing, leading to a growing market for automotive parts. In recent years, automotive parts manufacturing plants have also developed rapidly. Some automotive parts require large-scale production using rotary progressive dies to significantly improve production efficiency.

[0003] Because stamping dies need to continuously process aluminum plates during operation, the temperature of the dies themselves will rise rapidly. At this time, lubricating oil is needed to lubricate the surface of the dies or the aluminum plates to be stamped, so that a lubricating film is formed between the aluminum plates and the dies, which reduces friction and improves the precision and quality of the stamped parts.

[0004] In existing stamping equipment, when lubricating the surface of aluminum sheets with lubricating oil, the lubricating oil is typically placed directly into a container and sprayed onto the surface using an oil spraying mechanism. While this achieves lubrication, it only lubricates one outer side of the aluminum sheet, resulting in uneven lubrication and an unsatisfactory effect. Furthermore, the lubricating oil is prone to splashing during spraying, negatively impacting the stamping process. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a rotary aluminum profile stamping die for the production of automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary aluminum profile stamping die for automotive parts production includes a processing table. A turntable is rotatably mounted on the top of the processing table, and multiple lower dies are mounted on the top of the turntable. A fixed plate is mounted on one outer wall of the processing table, and a telescopic cylinder is mounted on the top of the fixed plate. The output end of the telescopic cylinder passes through the fixed plate and is connected to an upper die. A feeding cylinder is rotatably mounted on the outer wall of the processing table away from the fixed plate. An oiling mechanism for automatically oiling the surface of the aluminum plate to be stamped is provided on the side of the feeding cylinder near the processing table. A pushing mechanism for automatically pushing the aluminum plate into the oiling mechanism for oiling is provided on the side of the feeding cylinder away from the processing table. A fixed frame is mounted at the center of the top of the turntable, and limiting mechanisms for limiting and fixing the aluminum plate falling on the top of the lower die are installed on the four outer walls of the fixed frame.

[0008] Optionally, the feed cylinder has a placement groove inside, the size of which is adapted to the size of the aluminum plate to be stamped.

[0009] Optionally, the oiling mechanism includes two first slide grooves opened on the outer wall of the feeding cylinder near the processing table. A first slider is installed inside each of the two first slide grooves, and a first moving block is installed at the end of each of the two first sliders away from the first slide groove.

[0010] Optionally, a first groove is provided on the outer wall of each of the two first moving blocks on the side away from the first slider, and a first double-ended screw is rotatably installed inside the two first grooves. Two rectangular blocks are installed on the outer wall of each of the two first double-ended screws.

[0011] Optionally, the two rectangular blocks are mounted with a movable plate at the ends away from the first double-ended screw. An oil-absorbing pad is installed on the outer wall of the two movable plates on the side that is close to each other. A connecting end is provided on the outer wall of the two movable plates on the side that is far from each other. A hose for connecting to an externally preset oil delivery mechanism is fitted on the outer wall of the two connecting ends.

[0012] Optionally, the pushing mechanism includes a push plate slidably installed inside the feeding cylinder, one end of the push plate extending into the feeding cylinder, and protrusions installed on both the upper and lower sides of the other end of the push plate.

[0013] Optionally, a drive motor and a slide bar are installed on the outer wall of the feeding cylinder on the side away from the processing table. A drive screw is installed at the output end of the drive motor, and two protrusions respectively cooperate with the outer walls of the drive screw and the slide bar.

[0014] Optionally, the limiting mechanism includes second slide grooves opened on the four outer walls of the fixed frame, a second slider installed inside each of the four second slide grooves, a rotating frame rotatably installed at the end of each of the four second sliders away from the second slide grooves, a third slide groove opened on the inner walls of both sides of the four rotating frames, and a third slider installed inside each of the two third slide grooves.

[0015] Optionally, the ends of the two third sliders away from the third slide groove are connected to a second moving block. A second groove is provided on one side of the outer wall of the second moving block. A second double-ended screw is rotatably installed inside the second groove. Two sliding blocks are installed on the outer wall of the second double-ended screw. A limit plate is rotatably installed on the ends of the two sliding blocks away from the second double-ended screw.

[0016] Optionally, a storage groove is provided on the outer wall of the two limiting plates on the side away from each other. A telescopic curtain is installed inside the two storage grooves. A connecting plate is installed on the end of the two curtains away from the storage groove. An electromagnet is installed on the outer wall of the two connecting plates on the side away from the curtain.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, when lubricating the surface of the aluminum plate to be stamped, the pusher mechanism on the side of the feeding cylinder away from the processing table can be used to drive the pusher plate to push the aluminum plate at the bottom from the inside of the placement groove and pass between the two oil-absorbing pads. The two oil-absorbing pads of the oiling mechanism can automatically lubricate the upper and lower surfaces of the aluminum plate, so that the lubrication of the aluminum edge surface is more uniform, which facilitates the subsequent aluminum plate stamping work.

[0019] 2. In this invention, after the aluminum plate is coated with oil by two oil-absorbing pads, it moves toward one of the lower molds. The limiting mechanism clamps and fixes the aluminum plate on both sides between the two oil-absorbing pads. As the second moving block moves and resets inside the rotating frame, it moves the clamped aluminum plate to the top of the lower mold and places it there. The aluminum plate can be placed in the center of the top of the lower mold, which improves the accuracy and automation of placing the aluminum plate on the top of the lower mold.

[0020] 3. In this invention, after the aluminum plate is placed on the top of the lower die, the positions of the two limiting plates of the second moving block are kept unchanged. As the turntable rotates 90 degrees counterclockwise, it will drive the other lower die on the top of the turntable to rotate to a position close to and parallel to the upper cylinder. Since the aluminum plate to be stamped on the top of the lower die is clamped and fixed by the corresponding two limiting plates during the rotation of the turntable, it will not fall from the top of the lower die. This further improves the stability and safety of the aluminum plate placed on the top of the lower die and avoids the problem that the aluminum plate cannot be stamped when the upper and lower dies are matched but the aluminum plate is not on the top of the lower die.

[0021] 4. In this invention, after the first lower die and the corresponding limiting mechanism are located directly below the upper die, the corresponding second moving block is controlled to move and reset inside the rotating frame, thereby driving the two limiting plates to be stored inside the rotating frame. The upper die and the lower die cooperate to stamp the aluminum plate. During the process of the telescopic cylinder stamping the aluminum plate on the top of the second lower die, the part is located on the top of the lower die. At this time, the corresponding second moving block can be used to move again inside the rotating frame towards the lower die, driving the two limiting plates to push the part stamped on the top of the lower die off, achieving the effect of automatic unloading of the formed part without manual unloading.

Detailed Implementation

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0033] Reference Figures 1-8 A rotary aluminum profile stamping die for automotive parts production includes a processing table 1, a turntable 5 rotatably mounted on the top of the processing table 1, multiple lower dies 6 mounted on the top of the turntable 5, a fixing plate 2 mounted on one side of the outer wall of the processing table 1, a telescopic cylinder 3 mounted on the top of the fixing plate 2, the output end of the telescopic cylinder 3 passing through the fixing plate 2 and connected to an upper die 4, a feeding cylinder 7 rotatably mounted on the outer wall of the processing table 1 away from the fixing plate 2, an oiling mechanism for automatically oiling the surface of the aluminum plate to be stamped is provided on the side of the feeding cylinder 7 near the processing table 1, a pushing mechanism for automatically pushing the aluminum plate into the oiling mechanism for oiling is provided on the side of the feeding cylinder 7 away from the processing table 1, and a fixing frame 8 mounted at the center of the top of the turntable 5, with limiting mechanisms mounted on the four outer walls of the fixing frame 8 for assisting in limiting and fixing the aluminum plate falling on the top of the lower die 6. A first driving device is pre-installed on one side of the outer wall of the processing table 1. The output end of the first driving device is connected to the rotating part of the feeding cylinder 7, thereby driving the feeding cylinder 7 to rotate and adjust.

[0034] As a technical optimization of the present invention, the inside of the feeding cylinder 7 is provided with a placement groove 11, the size of which is adapted to the size of the aluminum plate to be stamped. Multiple aluminum plates to be stamped can be temporarily stored together inside the placement groove 11.

[0035] As a technical optimization of the present invention, the oiling mechanism includes two first slide grooves 15 formed on the outer wall of the feeding cylinder 7 near the processing table 1. A first slider 16 is installed inside each of the two first slide grooves 15, and a first moving block 17 is installed at the end of each of the two first sliders 16 away from the first slide groove 15. A first linear motor is pre-installed inside each of the two first slide grooves 15. The two first linear motors can drive the two first sliders 16 to move up and down inside the corresponding first slide groove 15, thereby driving the two first moving blocks 17 to move up and down on one side of the outer wall of the feeding cylinder 7.

[0036] As a technical optimization of the present invention, each of the two first moving blocks 17 has a first groove 18 on its outer wall away from the first slider 16. A first double-ended screw 19 is rotatably mounted inside each of the two first grooves 18, and two rectangular blocks 20 are mounted on the outer wall of each of the two first double-ended screws 19. A second driving device is pre-installed on one side of the outer wall of each of the two first moving blocks 17. The output ends of the two second driving devices are respectively connected to one end of each of the two first double-ended screws 19, thereby driving the two first double-ended screws 19 to rotate inside the corresponding first grooves 18, and consequently driving the two rectangular blocks 20 to move towards or away from each other.

[0037] As a technical optimization of the present invention, a movable plate 14 is installed on the ends of the two rectangular blocks 20 away from the first double-headed screw 19. An oil-absorbing pad 22 is installed on the outer wall of the two movable plates 14 on their adjacent sides, and a connecting end is provided on the outer wall of the two movable plates 14 on their distant sides. A flexible hose 21 for connecting to an externally pre-set oil delivery mechanism is fitted onto the outer wall of each connecting end. When the two rectangular blocks 20 move towards each other or away from each other, they can simultaneously drive the two movable plates 14 to move towards each other or away from each other. Since the interiors of the two movable plates 14 are hollow, and multiple oil drain holes are provided on the outer wall of the adjacent sides of the two movable plates 14, after the external oil delivery mechanism delivers lubricating oil to the interiors of the two movable plates 14 through the two flexible hoses 21, the lubricating oil can be discharged through the multiple oil drain holes into the interiors of the two oil-absorbing pads 22 for temporary absorption and storage.

[0038] As a technical optimization of the present invention, the pushing mechanism includes a push plate 12 that is slidably installed inside the feeding cylinder 7. One end of the push plate 12 extends into the feeding cylinder 7, and protrusions 36 are installed on both the upper and lower sides of the other end of the push plate 12.

[0039] As a technical optimization of the present invention, a drive motor and a slide bar 35 are installed on the outer wall of the feeding cylinder 7 away from the processing table 1. A drive screw 13 is installed at the output end of the drive motor, and two protrusions 36 respectively cooperate with the outer walls of the drive screw 13 and the slide bar 35. The feeding cylinder 7 has an outlet connected to the placement groove 11 near the two oil-absorbing pads 22. The length of the outlet is greater than the width of the placement groove 11, so that the aluminum plate can only be discharged outward through the outlet. The drive motor drives the drive screw 13 to rotate, which in turn drives the protrusions 36 to move on the surface of the drive screw 13. This allows the push plate 12 located inside the feeding cylinder 7 to push the aluminum plate placed at the bottom until it is pushed between the two oil-absorbing pads 22 and passes through it. This allows the two oil-absorbing pads 22 to automatically apply lubricating oil to both the top and bottom surfaces of the aluminum plate, facilitating subsequent stamping operations.

[0040] As a technical optimization of the present invention, the limiting mechanism includes four second slide grooves 23 opened on the four outer walls of the fixed frame 8. Each of the four second slide grooves 23 has a second slider 24 installed inside. A rotating frame 9 is rotatably mounted on the end of each of the four second sliders 24 away from the second slide groove 23. Each of the two inner walls of the rotating frame 9 has a third slide groove 25 opened on both sides. A third slider 27 is installed inside each of the four second slide grooves 23. A second linear motor is pre-installed inside each of the four second slide grooves 23, which can drive the four second sliders 24 to move up and down within the corresponding second slide groove 23. A third driving device is pre-installed inside each of the four second sliders 24, and the output ends of multiple third driving devices are respectively connected to the rotating parts of the rotating frame 9, thereby enabling multiple rotating frames 9 to rotate and adjust. A third linear motor is pre-installed inside each of the third slide grooves 25, which can drive the third slider 27 to move back and forth within the third slide groove 25.

[0041] As a technical optimization of the present invention, the ends of the two third sliders 27 away from the third slide groove 25 are connected to a second moving block 26. A second groove 28 is formed on one outer wall of the second moving block 26. A second double-ended screw 29 is rotatably installed inside the second groove 28. Two sliding blocks 30 are installed on the outer wall of the second double-ended screw 29. A limit plate 10 is rotatably installed on the ends of the two sliding blocks 30 away from the second double-ended screw 29. While the two third sliders 27 move, they can drive the second moving block 26 to move back and forth inside the rotating frame 9. A fourth driving device is preset inside the second moving block 26. The output end of the fourth driving device is connected to one end of the second double-ended screw 29, thereby driving the second double-ended screw 29 to rotate inside the second groove 28, which in turn drives the two sliding blocks 30 and the two limit plates 10 to move towards or away from each other. A servo motor is preset inside each of the two sliding blocks 30. The output end of the servo motor is connected to the rotating part of the limit plate 10, thereby driving the limit plate 10 to rotate and adjust.

[0042] As a technical optimization of the present invention, a storage groove 31 is provided on the outer wall of the two limiting plates 10 on the side away from each other. A telescopic curtain 32 is installed inside the two storage grooves 31. A connecting plate 33 is installed on the end of the two curtains 32 away from the storage grooves 31. An electromagnet 34 is installed on the outer wall of the two connecting plates 33 on the side away from the curtains 32. By controlling the servo motors inside the two sliding blocks 30 to start, the two limit plates 10 with the connecting plates 33 on one side are rotated to a close position. Then, with the help of the rotation of the second double-headed screw 29, the two limit plates 10 are moved towards the close direction. After the two electromagnets 34 are energized and started, the two limit plates 10 are moved towards the close direction until they are in contact. The two electromagnets 34 are then magnetically attracted to each other. Then, the second double-headed screw 29 is reversed to move the two limit plates 10 away from each other. With the magnetic attraction of the two electromagnets 34, the shielding curtains 32 inside the two storage slots 31 are pulled open to facilitate the shielding and protection of the top of the lower mold 6.

[0043] In this invention, when the user uses the device, multiple aluminum plates to be stamped are placed together in the placement groove 11 inside the feeding cylinder 7. The user then controls the external oil supply mechanism to deliver lubricating oil through two hoses 21 to the interior of two moving plates 14, allowing the interior of the two oil-absorbing pads 22 to temporarily absorb and store the discharged lubricating oil. Next, the user controls the drive screw 13 to rotate, causing one end of the push plate 12 to move inside the feeding cylinder 7. When the aluminum plate at the bottom is pushed from inside the placement groove 11 through the two oil-absorbing pads 22, the aluminum plate will squeeze the two oil-absorbing pads 22, causing the two oil-absorbing pads to... The lubricating oil inside pad 22 can be automatically applied to both the top and bottom surfaces of the aluminum plate, automatically lubricating both sides. The lubricating oil forms a lubricating film between the aluminum plate and the mold, reducing the friction between the aluminum plate and the mold, and lowering the frictional resistance during the stamping process. This also helps to reduce the deformation, cracking, and surface defects of the aluminum plate, improving the forming accuracy and surface quality of the stamped parts. At the same time, the lubricating properties of the lubricating oil can reduce the friction and vibration between the aluminum plate and the mold, thereby reducing the noise and vibration generated during the stamping process, providing a better working environment, and facilitating subsequent aluminum plate stamping work.

[0044] After being coated with oil by the two oil-absorbing pads 22, the aluminum plate moves toward one of the lower molds 6, as if... Figure 2 As shown, the second moving block 26, which is close to the upper feed cylinder 7, can be controlled to move inside the rotating frame 9 towards the lower mold 6. This causes the two limiting plates 10 to move synchronously towards the two oil-absorbing pads 22. After the two limiting plates 10 move to both sides of the two oil-absorbing pads 22, the second double-headed screw 29 is controlled to rotate, causing the two limiting plates 10 to move towards each other. This clamps and fixes the aluminum plate between the two oil-absorbing pads 22. As the second moving block 26 moves and resets inside the rotating frame 9, it moves the clamped and fixed aluminum plate to the top of the lower mold 6. The aluminum plate can be placed in the center of the top of the lower mold 6, improving the accuracy and automation of placing the aluminum plate on the top of the lower mold 6.

[0045] The positions of the second moving block 26 and the two limiting plates 10 are kept unchanged. As the turntable 5 rotates 90 degrees counterclockwise, it will drive the other lower die 6 on the top of the turntable 5 to rotate to a position close to and parallel to the loading cylinder 7. Repeat the above steps so that the pushing mechanism, the oiling mechanism and the other limiting mechanism cooperate to accurately place the aluminum plate at the bottom of the placement slot 11 after oiling on the top of the other lower die 6. Then, continue to control the turntable 5 to rotate 90 degrees counterclockwise, so that the first lower die 6 and the corresponding limiting mechanism can rotate to directly below the upper die 4. Since the aluminum plate to be stamped on the top of the lower die 6 is clamped and fixed by the corresponding two limiting plates 10 during the rotation of the turntable 5, it will not fall from the top of the lower die 6. This further improves the stability and safety of the aluminum plate placed on the top of the lower die 6, and avoids the problem that the aluminum plate cannot be stamped when the upper die 4 and the lower die 6 cooperate.

[0046] After the first lower die 6 and its corresponding limiting mechanism are positioned directly below the upper die 4, the corresponding second moving block 26 is controlled to move and reset inside the rotating frame 9, thereby causing the two limiting plates 10 to be housed inside the rotating frame 9. At this time, the telescopic cylinder 3 extends and retracts, causing the upper die 4 to move rapidly downwards to stamp the aluminum plate on top of the lower die 6. After the first aluminum plate is stamped, the turntable 5 is controlled to rotate counterclockwise by 90 degrees, causing the first lower die 6 and the stamped part to rotate to the left end of the processing table 1. The telescopic cylinder 3 continues to extend and retract, causing the upper die 4 to move downwards to stamp the aluminum plate on top of the second lower die 6. During the stamping process, while the telescopic cylinder 3 is stamping the aluminum plate on the top of the second lower die 6, the first stamped part, which has been stamped after rotating to the left end of the processing table 1, is located on the top of the first lower die 6. At this time, the second double-headed screw 29 can be controlled to drive the two limiting plates 10 to move towards each other and abut against each other. Then, with the help of the corresponding second moving block 26, it moves again towards the lower die 6 inside the rotating frame 9, driving the two limiting plates 10 to push down the stamped part on the top of the lower die 6, thus achieving the effect of automatically unloading the formed part without the need for manual unloading.

[0047] If an industrial camera or other related equipment for automatic surface inspection of the formed parts is pre-installed near the processing table 1, the turntable 5 can rotate the stamped lower die 6 and the parts together to the left end of the processing table 1. The pre-installed industrial camera or other related equipment can then identify and inspect the surface of the parts. If the parts are defect-free, they can be pushed down directly. If the parts are defective, two corresponding limit plates 10 can be controlled to clamp and fix them. Then, the second slider 24 can be used to move the rotating frame 9 and other components upwards, thereby rotating the defective parts upwards to a position higher than the lower die 6. The rotating frame 9 can then be controlled to rotate 180 degrees, thereby flipping the clamped parts together. Then, the second slider 24 is controlled to drive the rotating frame 9 and other components to move downwards and reset. Then, the second moving block 26 and the limiting plate 10 push it down. A feeding slide is preset at the left end of the processing table 1. After the two limiting plates 10 remove the formed part from the top of the lower mold 6, the part will fall on the top of the feeding slide and slide downwards. With the above steps, qualified parts slide downwards and are discharged in their original state, while unqualified parts slide downwards and are discharged in an upside-down state. The staff who pick up the parts can quickly identify the unqualified parts and classify and collect them, avoiding the need to spend more time on the surface identification and sorting of the parts later, and further improving the efficiency of part stamping.

[0048] If a portion of the stamped aluminum sheet becomes stuck inside the lower die 6 and cannot be automatically ejected upwards by the pre-set ejection mechanism inside the lower die 6, the corresponding second moving block 26 can be used to move and extend the two limiting plates 10 from inside the rotating frame 9. After the two extended limiting plates 10 are positioned on both sides of the component, the corresponding second double-headed screw 29 rotates, causing the two limiting plates 10 to move towards each other, clamping and fixing the component stuck inside the lower die 6 on both sides. Then, the corresponding second slider 24 is controlled to move upwards inside the second slide groove 23, which in turn causes the two limiting plates 10 to pull the component stuck inside the lower die 6 upwards until it is pulled out of the lower die 6. This allows the limiting mechanism to handle such unexpected situations, further improving the applicability of the limiting mechanism.

[0049] After all the aluminum plates have been stamped, if there is still lubricating oil inside the two oil-absorbing pads 22, the two first sliders 16 can be controlled to move the two first moving blocks 17 and other components upward to one end, thereby moving the two oil-absorbing pads 22 upward together. Then, the loading cylinder 7 is controlled to rotate towards the processing table 1 in an inclined state. By controlling the two first double-headed screws 19 to rotate together, the two moving plates 14 are moved towards each other, so that the two oil-absorbing pads 22 are squeezed by the two moving plates 14 and discharged downward to the lower end into the lower die 6. This provides lubrication and maintenance for the lower die 6 when it is not in use, preventing rust and corrosion when the lower die 6 is not in use and improving the protection effect of the lower die 6.

[0050] Furthermore, after the lubricating oil remaining inside the two oil-absorbing pads 22 is squeezed into the interior of the multiple lower molds 6, the multiple second moving blocks 26 can be simultaneously controlled to move inside the corresponding rotating frame 9, thereby causing the two corresponding limiting plates 10 to extend out from inside the rotating frame 9. The multiple limiting plates 10 are controlled to rotate 180 degrees, causing the side of the multiple limiting plates 10 with the connecting plate 33 to rotate to a position close to the lower mold 6. Then, the multiple electromagnets 34 are energized to generate magnetism, and the multiple second double-headed screws 29 are controlled to drive the corresponding two limiting plates 10 toward each other. The two electromagnets 34 are magnetically attracted and fixed together. Then, multiple second double-headed screws 29 are reversed, causing the corresponding two limit plates 10 to move away from each other. This causes the two shielding curtains 32 to be pulled open above the lower mold 6. Finally, multiple second sliders 24 are controlled to move downward inside the corresponding second slide groove 23, which in turn causes the opened shielding curtains 32 to cover the top of the corresponding lower mold 6, protecting the lower mold 6 and preventing external dust and other debris from falling into the lower mold 6 and affecting its subsequent use.
