Description

Technical Field

[0001] The invention relates to the technical field of automobile parts production, and in particular to a rotary aluminum profile stamping die for automobile parts production. Background Art

[0002] Auto parts are the various units that make up the whole car and a kind of product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is getting bigger and bigger. In recent years, auto parts manufacturers have also developed rapidly. Some auto parts need to be mass-produced through rotary continuous stamping dies during the production and processing process to greatly improve the production efficiency of auto parts.

[0003] Since the stamping die needs to continuously process the aluminum plate during operation, the temperature of the die itself will rise quickly. At this time, it is necessary to lubricate the die surface or the surface of the aluminum plate to be stamped with lubricating oil to form a lubricating film between the aluminum plate and the die, which can reduce friction and improve the precision and quality of the stamping parts.

[0004] When the stamping device in the prior art uses lubricating oil to lubricate the surface of the aluminum plate, the lubricating oil is generally directly put into a container, and the lubricating oil is sprayed on the surface of the aluminum plate by means of an oil spraying mechanism. Although the lubrication effect of the aluminum plate can be achieved, this method can only lubricate the outer wall of one side of the aluminum plate, resulting in uneven lubrication of the aluminum edge surface, and the effect is not ideal. It is also easy to cause the lubricating oil to splash around during the process of spraying onto the surface of the aluminum plate, which has an adverse effect on the stamping work of the aluminum plate. Summary of the invention

[0015] Optionally, the two third sliding blocks are commonly connected to a second movable block at one end away from the third sliding slot, a second groove is opened on one side outer wall of the second movable block, a second double-headed screw is rotatably installed inside the second groove, two sliding blocks are installed on the outer wall of the second double-headed screw, and a limiting plate is rotatably installed on one end of the two sliding blocks away from the second double-headed screw.

Connecting plates are installed on the ends of the two curtains away from the storage grooves, and electromagnets are installed on the outer walls on the side away from the two connecting plates.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, when lubricating the surface of the aluminum plate to be stamped, the pushing mechanism on the side of the loading barrel away from the processing table can be used to drive the push plate to push the aluminum plate at the bottom from the inside of the placement groove to pass between the two oil absorption pads. The two oil absorption 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 is convenient for the subsequent aluminum plate stamping work.

[0020] 3. In the invention, after the aluminum plate is placed on the top of the lower die, the positions of the two limit plates of the second movable block are controlled to remain unchanged. As the turntable rotates 90 degrees counterclockwise, the other lower die on the top of the turntable will be driven to rotate to a position close to and parallel to the upper barrel. Since the aluminum plate to be stamped on the top of the lower die is clamped and fixed by the corresponding two limit plates during the rotation of the turntable, it will not fall down from the top of the lower die, further improving the stability and safety of the aluminum plate placed on the top of the lower die, avoiding the subsequent upper die and lower die matching, but the aluminum plate is not on the top of the lower die, resulting in the problem that the aluminum plate cannot be stamped.

[0021] 4. In the invention, after the first lower die and the corresponding limit 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 limit 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 component 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 in the direction close to the lower die, driving the two limit plates to push down the component stamped on the top of the lower die, thereby achieving the effect of automatic unloading of the formed components without manual unloading.

[0040] As a technical optimization solution of the present invention, the limiting mechanism includes a second slide groove 23 opened on the four outer walls of the fixed frame 8, and a second slider 24 is installed inside the four second slide grooves 23. The four second sliders 24 are rotatably installed with a rotating frame 9 at one end away from the second slide groove 23.

[0041] As a technical optimization scheme of the present invention, the ends of the two third sliders 27 away from the third slide slot 25 are connected to the second moving block 26, and the outer wall of one side of the second moving block 26 is provided with a second groove 28, and the second double-headed screw 29 is rotatably installed inside the second groove 28. Two sliding blocks 30 are installed on the outer wall of the second double-headed screw 29, and the ends of the two sliding blocks 30 away from the second double-headed screw 29 are rotatably installed with the limit plate 10. When the two third sliders 27 move, they can drive the second moving block 26 to move back and forth inside the rotating frame 9; and a fourth driving device is preset inside the second moving block 26, and the output end of the fourth driving device is connected to one end of the second double-headed screw 29, so that the second double-headed screw 29 can be driven to rotate inside the second groove 28, and the two sliding blocks 30 and the two limit plates 10 can be driven to move in the direction of approaching or moving away from each other; servo motors are preset inside the two sliding blocks 30, and the output end of the servo motors is connected to the rotating part of the limit plate 10, so that the limit plate 10 can be driven to rotate and adjust.

[0042] As a technical optimization scheme of the present invention, the outer walls of the two limit plates 10 on the side away from each other are provided with storage grooves 31, and retractable shielding curtains 32 are installed inside the two storage grooves 31. Connecting plates 33 are installed on the ends of the two shielding curtains 32 away from the storage grooves 31, and electromagnets 34 are installed on the outer walls of the two connecting plates 33 on the side away from the shielding curtains 32. By controlling the servo motor inside the two sliding blocks 30 to start, the two limit plates 10 with one side of the connecting plate 33 are driven to rotate to a close position, and then with the help of the rotation of the second double-headed screw 29, the two limit plates 10 are driven to move in the direction of approaching each other. After the two electromagnets 34 are powered on and started, until the two limit plates 10 move in the direction of approaching each other to abutment, the two electromagnets 34 are magnetically attracted to each other, and then the second double-headed screw 29 is controlled to reverse, driving the two limit plates 10 to move in the direction of moving away from each other. With the help of the magnetic attraction and fixing effect of the two electromagnets 34, the shielding curtains 32 inside the two storage slots 31 are pulled and unfolded, which is convenient for shielding and protecting the top of the lower mold 6.

[0043] In the present invention, when the user uses the device, after placing multiple aluminum plates to be stamped together in the placement groove 11 inside the upper barrel 7, the external oil delivery mechanism is controlled to deliver the lubricating oil to the inside of the two movable plates 14 through the two hoses 21, so that the inside of the two oil-absorbing pads 22 can absorb and temporarily store the discharged lubricating oil, and then the driving screw 13 is controlled to rotate, driving one end of the push plate 12 to move inside the upper barrel 7, and the aluminum plate at the bottom is pushed from the inside of the placement groove 11 to pass between the two oil-absorbing pads 22. The aluminum plate will squeeze the two oil-absorbing pads 22, causing the two oil-absorbing pads 22 to absorb the oil. The lubricating oil inside the pad 22 can be automatically applied to the upper and lower surfaces of the aluminum plate to automatically lubricate the upper and lower surfaces of the aluminum plate. 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 reducing the friction resistance during the stamping process. This also helps to reduce the deformation, cracking and surface defects of the aluminum plate, and improve 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 the subsequent aluminum plate stamping work.

[0044] The aluminum plate after being oiled by the two oil absorbing pads 22 moves toward the direction close to one of the lower molds 6. Figure 2 As shown, the second moving block 26 close to the loading barrel 7 can be controlled to move in the direction close to the lower mold 6 inside the rotating frame 9, and the two limit plates 10 can be driven to move synchronously in the direction close to the two oil absorption pads 22. After the two limit plates 10 move to both sides of the two oil absorption pads 22, the second double-headed screw 29 is controlled to rotate, driving the two limit plates 10 to move in the direction close to each other, clamping and fixing the two sides of the aluminum plate between the two oil absorption pads 22, and as the second moving block 26 moves and resets inside the rotating frame 9, the clamped aluminum plate is driven to move to the top of the lower mold 6 for placement, and the aluminum plate can be placed in the center of the top of the lower mold 6, thereby 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 limit plates 10 are controlled to remain unchanged at this time. As the turntable 5 rotates 90 degrees counterclockwise, the other lower mold 6 on the top of the turntable 5 will be driven to rotate to a position close to and parallel to the upper barrel 7. The above steps are repeated to make the pushing mechanism, the oiling mechanism and the other limit mechanism cooperate to place the aluminum plate at the bottom of the placement groove 11 accurately on the top of the other lower mold 6 after oiling. Then the turntable 5 is continued to be controlled to rotate 90 degrees counterclockwise, so as to drive the first lower mold 6 and the corresponding limit mechanism to rotate to just below the upper mold 4. Since the aluminum plate to be stamped on the top of the lower mold 6 is clamped and fixed by the corresponding two limit plates 10 during the rotation of the turntable 5, it will not fall down from the top of the lower mold 6, further improving the stability and safety of the aluminum plate placed on the top of the lower mold 6, avoiding the subsequent upper mold 4 and lower mold 6 cooperation, but the aluminum plate is not on the top of the lower mold 6, resulting in the problem that the aluminum plate cannot be stamped.

[0046] After the first lower die 6 and the corresponding limit mechanism are located directly below the upper die 4, the corresponding second moving block 26 is controlled to move and reset inside the rotating frame 9, and the two limit plates 10 are driven to be stored inside the rotating frame 9. At this time, the telescopic end of the telescopic cylinder 3 drives the upper die 4 to move downward quickly, and the aluminum plate on the top of the lower die 6 is stamped. After the first aluminum plate is stamped, the turntable 5 is controlled to rotate 90 degrees counterclockwise, driving the first lower die 6 and the stamped parts to rotate to the left end of the processing table 1. The telescopic end of the telescopic cylinder 3 continues to drive the upper die 4 to move downward, and the aluminum plate on the top of the second lower die 6 is stamped. The plate is stamped. During the process of the telescopic cylinder 3 stamping the aluminum plate on the top of the second lower die 6, the first stamped component after stamping is rotated to the left end of the processing table 1 and 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 limit plates 10 to move in a direction close to each other and abut against each other, and then the corresponding second moving block 26 is used to move again in the direction close to the lower die 6 inside the rotating frame 9, driving the two limit plates 10 to push down the stamped component on the top of the lower die 6, thereby achieving the effect of automatic unloading of the formed components without manual unloading.

[0047] If an industrial camera or other related equipment for automatically detecting the surface of the formed component is preset near the processing table 1, the surface of the component can be identified and detected by the preset industrial camera or other related equipment after the turntable 5 drives the stamped lower mold 6 and the component to rotate to the left end of the processing table 1. If the component has no defects, it can be directly pushed down. If the component has defects, the two corresponding limit plates 10 can be controlled to clamp and fix it, and the second slider 24 can be used to drive the rotating frame 9 and other components to move upward, and the unqualified component can be driven to rotate upward to a position higher than the lower mold 6, and the rotating frame 9 can be controlled to rotate 180 degrees, so as to drive the clamped component to flip over together, and then Then the second slider 24 is controlled to drive the rotating frame 9 and other components to move downward and reset, and then the second moving block 26 and the limit plate 10 are used to push it down. A feeding slide is preset at the left end of the processing table 1. After the two limit plates 10 remove the formed components from the top of the lower mold 6, the components will fall on the top of the feeding slide and slide downward. With the help of the above steps, qualified components can slide downward in their original state and be discharged, and unqualified components can slide downward in an inverted state and be discharged. The staff who take the components later can quickly identify the unqualified components and classify them for collection, avoiding the need to spend more time on component surface identification, detection and sorting in the future, thereby further improving the efficiency of component stamping.

[0048] For example, when part of the aluminum plate after stamping is stuck in the lower mold 6 and the preset ejecting mechanism in the lower mold 6 cannot automatically eject it upward, the corresponding second moving block 26 can be used to drive the two limit plates 10 to move and extend from the inside of the rotating frame 9, so that the two extended limit plates 10 are located on both sides of the component. Then, the corresponding second double-headed screw 29 is rotated to drive the two limit plates 10 to move in a direction close to each other, clamping and fixing the two sides of the component stuck in the lower mold 6, and then controlling the corresponding second slider 24 to move upward in the second slide groove 23, driving the two limit plates 10 to pull the component stuck in the lower mold 6 upward until it is pulled out from the lower mold 6, so that the limit mechanism can handle such unexpected situations, further improving the applicability of the limit mechanism.

[0049] After the stamping work on all aluminum plates is completed, if there is still lubricating oil temporarily stored in the two oil absorption pads 22, the two first sliders 16 can be controlled to drive the two first moving blocks 17 and other components to move upward to one end distance, and then drive the two oil absorption pads 22 to move upward together, and then control the loading barrel 7 to rotate in a tilted state in the direction close to the processing table 1, and control the two first double-headed screws 19 to rotate together, drive the two moving plates 14 to move in a direction close to each other, so that the two oil absorption pads 22 are squeezed by the two moving moving plates 14 and discharged downward toward the lower end to the inside of the lower mold 6, and lubricate and maintain the lower mold 6 when it is not used later, so as to avoid rust and corrosion when the lower mold 6 is not in use, thereby improving the protection effect of the lower mold 6.

[0050] After the lubricating oil remaining in 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 synchronously controlled to move inside the corresponding rotating frame 9, and the corresponding two limit plates 10 can be driven to extend from the interior of the rotating frame 9, and the multiple limit plates 10 are controlled to rotate 180 degrees, driving the side of the multiple limit plates 10 with the connecting plate 33 to rotate to a position close to the lower mold 6, and then the multiple electromagnets 34 are controlled to be energized to generate magnetism, and the multiple second double-headed screws 29 are controlled to drive the corresponding two limit plates 10 to move closer to each other. direction and abut against each other, so that the two electromagnets 34 are magnetically fixed, and then the multiple second double-headed screws 29 are controlled to reverse, driving the corresponding two limit plates 10 to move in opposite directions, driving the two shielding curtains 32 to be pulled and unfolded above the lower mold 6, and finally controlling the multiple second sliders 24 to move downward inside the corresponding second slide grooves 23, driving the unfolded shielding curtains 32 to cover the top of the corresponding lower mold 6, and covering and protecting the lower mold 6 to prevent external dust and other debris from falling into the interior of the lower mold 6, which will affect the subsequent use of the lower mold 6.
