Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a stamping equipment for aluminum material processing and forming. Background Technology

[0002] Aluminum stamping equipment is a specialized device used to process raw materials such as aluminum plates, strips, or coils into parts of specific shapes through stamping processes. The core objective of aluminum stamping equipment is to balance efficiency and quality, and to achieve high-yield, low-cost mass production through targeted design.

[0003] Patent CN217289982U discloses a stamping device for aluminum processing and forming, including a processing table. A placement block and a support plate are fixedly connected to the top of the processing table. This stamping device for aluminum processing and forming achieves good guiding effect by incorporating a guide column, guide groove, sheet, guide cylinder, limit rod, rollers, and pressure sensor. When the raw material is placed on the placement block, the first hydraulic push rod is activated, causing the connecting plate and stamping block to descend. Simultaneously, the guide column descends into the guide cylinder. The rollers inside the guide cylinder roll against the outer wall of the limit rod, increasing the fit between the guide column and the guide cylinder. When the guide column descends into the first matching groove, it applies vertical pressure to the sheet. The pressure sensor detects the pressure, allowing the raw material to be stamped, effectively improving the stamping accuracy and thus the quality of aluminum processing.

[0004] When the above-mentioned device is in operation, it is difficult to automatically unload the stamped workpieces, which may lead to workers manually picking up the materials near the mold, resulting in safety risks. In addition, it is also difficult to buffer the workpieces that stick to the mold and fall off. Therefore, a stamping device for aluminum processing and forming is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a stamping device for aluminum material processing and forming, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a stamping device for aluminum material processing and forming, comprising a base, a punch press body fixedly connected to the top of the base, an upper die and a lower die installed at the stamping part of the punch press body, a material discharge mechanism installed on the top of the base, a material feeding mechanism inside the punch press body, and a degreasing mechanism installed at the front of the punch press body. The material discharge mechanism includes: a support column, a mounting seat, a transmission wheel, a connecting arm, a buffer plate, a roller brush, a pusher plate, and a pusher wheel. The support column is fixedly connected to the top of the base, the mounting seat is rotatably connected to the top of the support column, and the mounting seat is driven by a motor inside the support column. The transmission wheel is rotatably connected to the inner wall of the mounting seat and is driven by a motor inside the mounting seat. The connecting arm is slidably connected to the inner wall of the mounting seat. The buffer plate is hinged to the top of the connecting arm by a torsion spring, and a buffer spring is also provided at the angle between the connecting arms. The spring, the roller brush is fixedly connected to the bottom of the connecting arm, the pusher plate is fixedly connected to the side of the connecting arm near the buffer plate, the pusher wheel is fixedly connected to the top of the mounting base, the two sides of the connecting arm are in contact with the transmission wheel, the pusher wheel is located on the movement trajectory of the buffer plate, and the upper and lower dies are both equipped with ejector pins to eject the workpiece after stamping. After the device completes one stamping process, the ejector pin inside the lower die ejects the aluminum stamped part, the motor inside the support column starts, drives the mounting base to rotate counterclockwise, the rotation of the mounting base drives the connecting arm to rotate to the lower die, and then the motor inside the mounting base drives the transmission wheel to rotate, the rotation of the transmission wheel drives the connecting arm to move forward, the forward movement of the connecting arm drives the pusher plate to push out the workpiece, thereby avoiding workers manually picking up materials near the mold, reducing the risk of safety accidents, requiring no manual intervention, and also realizing the synchronous operation of stamping and unloading, reducing downtime and improving equipment utilization. During the upward movement of the upper die after stamping, the workpiece may be lifted. When the ejector pin inside the upper die pushes the workpiece out, the connecting arm moves forward, and the workpiece falls onto the buffer plate. The buffer plate cushions the falling workpiece to prevent scratches, dents, or deformation on the surface of the stamped part due to impact. After the workpiece falls, the connecting arm moves back, and the movement of the connecting arm drives the buffer plate to move until the bottom of the buffer plate contacts the push roller. As the buffer plate moves, the push roller pushes the buffer plate to flip the workpiece back onto the surface of the lower die. Then, the connecting arm drives the push plate to push the workpiece out again. During the movement of the connecting arm, the roller brush moves along with it to clean the inner wall of the lower die, which can prevent residue from squeezing and damaging the die surface, maintain the smoothness of the die, and prevent die wear caused by material scratches.

[0007] Preferably, the feeding mechanism includes: a fixed block, a threaded rod, a push plate, a return spring, a spur gear, a rack, a friction block, a slider, and an internal threaded ring. The fixed block is fixedly connected to the inner wall of the punch press body. The threaded rod is rotatably connected to the inner wall of the fixed block. The internal threaded ring is movably connected to the circumferential surface of the threaded rod. The push plate is fixedly connected to the outer wall of the internal threaded ring. The slider is fixedly connected to the outer wall of the internal threaded ring, and the slider and push plate are symmetrically arranged. The return spring is fixedly connected between the fixed block and the internal threaded ring. The spur gear is fixedly connected to... On one circumferential surface of the threaded rod, the rack is slidably connected to the inner wall of the punch press body. The friction block is hinged to the rack on the side away from the punch press body via a torsion spring. The feeding mechanism also includes: an L-shaped limiting plate, a lifting and lowering rotating rod, a friction wheel, and a conveyor belt. The L-shaped limiting plate is fixedly connected to the side of the connecting arm away from the push plate. The lifting and lowering rotating rod is rotatably connected to the surface of the L-shaped limiting plate and is driven by a motor inside the connecting arm. The friction wheel is fixedly connected to the inner wall of the lifting and lowering rotating rod via a motor. Driven by an electric motor, the conveyor belt is installed inside the punch press body to transport aluminum material. The slider is slidably connected to a slot on the inner wall of the punch press body. The spur gear meshes with the rack. When the lifting and lowering rotating rod is lowered, the friction wheel contacts the aluminum material. The push plate is located on the movement trajectory of the L-shaped limit plate. The surface of the friction wheel has an inclined groove. After the material is discharged, the conveyor belt starts to transport the aluminum material to the lower die. The motor inside the support column drives the mounting base to rotate clockwise. The rotation of the mounting base drives the connecting arm to rotate. At this time, the L-shaped limit plate on the side of the connecting arm away from the push plate rotates clockwise. The limiting plate contacts and presses the push plate, causing it to move forward. The forward movement of the push plate drives the internal threaded ring to move. The movement of the threaded ring drives the threaded rod to rotate through the threads on its inner wall. The rotation of the threaded rod drives the spur gear to rotate. The rotation of the spur gear drives the rack that meshes with it to move. The movement of the rack drives the friction block to move and contact the aluminum material, pushing the aluminum material out of the conveyor belt to the lower die stamping area. The aluminum material is pushed out through the friction block. There is no need for frequent manual feeding, realizing the synchronous operation of stamping and feeding, reducing downtime. In conjunction with the discharge mechanism, it forms a complete automated production line and improves the overall production capacity. When the friction block pushes the aluminum material to the lower die stamping area, the aluminum material may bounce off due to collision with the L-shaped limiting plate and fail to fully enter the lower die stamping area. Therefore, after the friction block pushes the aluminum material, the lifting and lowering rod is driven by the motor inside the connecting arm to fall down, so that the friction wheel contacts the aluminum material. Then, the electric motor on the inner wall of the lifting and lowering rod starts to drive the friction wheel to rotate and rub against the aluminum material, making the aluminum material more closely adhere to the L-shaped limiting plate. The position of the aluminum material is adjusted again by the friction wheel, which further improves the accuracy of the feeding mechanism and ensures that the feeding position is aligned with the center of the mold each time, avoiding stamping burrs, dimensional deviations and mold damage caused by misalignment.

[0008] Preferably, the degreasing mechanism includes: a water tank, a guide rail, a material support plate, a first bevel gear, and a second threaded rod. The water tank is fixedly connected to the front of the punch press body, the guide rail is fixedly connected to the inner wall of the water tank, the material support plate is slidably connected to the inner wall of the guide rail, the second threaded rod is slidably connected to the inner wall of the lower die, and the first bevel gear is rotatably connected to the side of the lower die near the water tank. The degreasing mechanism also includes: a second bevel gear, a third threaded rod, an internal threaded sleeve, a connecting plate, and a stop block. The connecting plate is fixedly connected to the side of the lower die near the water tank. On one side of the water tank, the threaded rod three is rotatably connected to the inner wall of the connecting plate, and the internal threaded sleeve is movably connected to the circumferential surface of the threaded rod three. The inner wall of the bevel gear one is threaded, and the thread on the inner wall of the bevel gear one is movably connected to the threaded rod two. The internal threaded sleeve is fixedly connected to the support plate. The bevel gear one and bevel gear two mesh with each other to form a gear set. An elastic telescopic component is installed on the inner wall of the guide rail for resetting the support plate. After the workpiece is stamped, it is pushed into the water tank by the pusher plate and falls onto the support plate. The material plate contacts the cleaning fluid in the water tank to degrease the workpiece, removing stamping oil, metal shavings, and other dirt from the workpiece surface. This shortens subsequent processing time and the overall production cycle. It also prevents the workpiece from being contaminated with dust or oil during transport or stacking. When the connecting arm moves forward, pushing the pusher plate out of the workpiece, the pusher plate contacts and pushes the stop block. The stop block moves, causing the threaded rod two to move. The threaded rod two moves, driving the bevel gear one to rotate through its surface threads. The rotation of bevel gear one drives the meshing bevel gear two to rotate, which in turn drives the threaded rod three to rotate. The rotation of threaded rod three pushes the inner threaded sleeve downward through its surface threads. The downward movement of the inner threaded sleeve pushes the support plate downward and stretches the elastic telescopic component installed on the inner wall of the guide rail, immersing the pusher plate and workpiece in the cleaning fluid. As the pusher plate moves back, the force of the elastic telescopic component resets the support plate. With the up and down movement of the support plate, the dirt on the surface of the workpiece immersed in the cleaning fluid is carried away by the flow of the cleaning fluid, further improving the cleaning effect of the workpiece.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This stamping device for aluminum processing and forming can avoid workers manually picking up materials near the mold, reducing the risk of safety accidents. It requires no manual intervention and can also realize the synchronous operation of stamping and unloading, reducing downtime and improving equipment utilization. It can also buffer the workpieces falling from the mold to prevent scratches, dents or deformation on the surface of the stamped parts due to impact. The roller brush can also clean the inner wall of the lower mold to prevent residual material from squeezing and damaging the mold surface, maintaining the smoothness of the mold and preventing mold wear caused by material scratches.

[0010] 2. This stamping device for aluminum processing and forming eliminates the need for frequent manual feeding, enabling synchronous operation of stamping and feeding, reducing downtime. In conjunction with the unloading mechanism, it forms a complete automated production line, improving overall production capacity. It can also readjust the position of the aluminum material through the friction wheel, further improving the accuracy of the feeding mechanism and ensuring that the feeding position is aligned with the mold center each time, avoiding stamping burrs, dimensional deviations, and mold damage caused by misalignment.

[0011] 3. This stamping device for aluminum processing and forming can remove stamping oil, metal shavings and other dirt from the surface of the workpiece, shorten the subsequent processing time and the overall production cycle. It can also prevent the workpiece from being contaminated with dust or oil in the environment during transportation or stacking. By moving the support plate up and down, the dirt on the surface of the workpiece immersed in the cleaning solution is carried away with the flow of the cleaning solution, further improving the cleaning effect of the workpiece.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figures 1-12One embodiment of the present invention is: a stamping device for aluminum material processing and forming, comprising a base 1, a punch press body 2 fixedly connected to the top of the base 1, an upper die 3 and a lower die 4 installed at the stamping part of the punch press body 2, a material discharge mechanism 5 installed on the top of the base 1, a material feeding mechanism 6 provided inside the punch press body 2, and a degreasing mechanism 7 installed at the front of the punch press body 2. The material discharge mechanism 5 includes: a support column 501, a mounting base 502, a transmission wheel 503, a connecting arm 504, a buffer plate 505, a roller brush 506, a pusher plate 507, and a pusher wheel 508. The support column 501 is fixedly connected to the top of the base 1, the mounting base 502 is rotatably connected to the top of the support column 501 and is driven by a motor inside the support column 501, the transmission wheel 503 is rotatably connected to the inner wall of the mounting base 502 and is driven by a motor inside the mounting base 502, the connecting arm 504 is slidably connected to the inner wall of the mounting base 502, and the buffer plate 505 is hinged to the top of the connecting arm 504 by a torsion spring. A buffer spring is also provided at the angle between the connecting arm 504 and the connecting arm 504. The roller brush 506 is fixedly connected to the bottom of the connecting arm 504. The pusher plate 507 is fixedly connected to the side of the connecting arm 504 near the buffer plate 505. The pusher 508 is fixedly connected to the top of the mounting base 502. The two sides of the connecting arm 504 are in contact with the transmission wheel 503. The pusher 508 is located on the movement trajectory of the buffer plate 505. The upper die 3 and the lower die 4 are both equipped with ejector pins to push the workpiece out after stamping. This can avoid workers manually picking up materials near the die, reducing the risk of safety accidents. No manual intervention is required. It can also realize the synchronous operation of stamping and material discharge, reduce downtime, and improve equipment utilization. It can also buffer the workpiece falling from the die to prevent the surface of the stamped parts from being scratched, dented or deformed due to impact. The roller brush 506 can also brush the inner wall of the lower die 4 to prevent residual material from squeezing and damaging the die surface, maintain the smoothness of the die, and prevent die wear caused by material scratches.

[0016] Working Principle: After the device completes one stamping process, the ejector pin inside the lower die 4 ejects the aluminum stamped part. The motor inside the support column 501 starts, driving the mounting base 502 to rotate counterclockwise. The rotation of the mounting base 502 drives the connecting arm 504 to rotate to the lower die 4. Subsequently, the motor inside the mounting base 502 drives the transmission wheel 503 to rotate. The rotation of the transmission wheel 503 drives the connecting arm 504 to move forward. The forward movement of the connecting arm 504 drives the pusher plate 507 to push out the workpiece, thus avoiding manual material handling near the die, reducing the risk of safety accidents. No manual intervention is required, and stamping and material discharge can be carried out simultaneously, reducing downtime and improving equipment utilization. During the upward movement of the upper die 3 after stamping, the workpiece may be lifted. When the ejector pin inside the upper die 3 pushes out the workpiece, the connecting arm 504 completes its forward movement, and the workpiece falls onto the buffer plate 505. The buffer plate 505 cushions the falling workpiece to prevent scratches, dents, or deformation on the surface of the stamped part due to impact. After the workpiece falls, the connecting arm 504 moves back. The movement of the connecting arm 504 drives the buffer plate 505 to move until the bottom of the buffer plate 505 contacts the push roller 508. As the buffer plate 505 moves, the push roller 508 pushes the buffer plate 505 to flip the workpiece back onto the surface of the lower mold 4. Then the connecting arm 504 drives the push plate 507 to push the workpiece out again. During the movement of the connecting arm 504, the roller brush 506 moves accordingly to brush the inner wall of the lower mold 4 to avoid residual material squeezing and damaging the mold surface, maintain the smoothness of the mold, and prevent mold wear caused by material scratches.

[0017] Please see Figures 1-12Based on the above embodiments, in another embodiment of the present invention, the feeding mechanism 6 includes: a fixed block 601, a threaded rod 602, a push plate 603, a return spring 604, a flat gear 605, a rack 606, a friction block 607, a slider 612, and an internal threaded ring 613.

The connecting arm 504 is located away from the pusher plate 507. The lifting and lowering rotating rod 609 is rotatably connected to the surface of the L-shaped limiting plate 608, and is driven by a motor inside the connecting arm 504. The friction wheel 610 is fixedly connected to the inner wall of the lifting and lowering rotating rod 609 via a motor, and is driven by an electric motor fixedly connected to the inner wall of the lifting and lowering rotating rod 609. The conveyor belt 611 is installed inside the punch press body 2 for conveying aluminum material. The slider 612 is slidably connected to the slotted section of the inner wall of the punch press body 2. The spur gear 605 meshes with the rack 606. When 609 is lowered, the friction wheel 610 will contact the aluminum material. The push plate 603 is located on the movement trajectory of the L-shaped limit plate 608. The friction wheel 610 has a slanted groove on its surface, eliminating the need for frequent manual feeding and enabling synchronous operation of stamping and feeding, reducing downtime. In conjunction with the discharge mechanism 5, it forms a complete automated production line, improving overall production capacity. The friction wheel 610 can also be used to readjust the position of the aluminum material, further improving the accuracy of the feeding mechanism 6 and ensuring that the feeding position is aligned with the mold center each time, avoiding stamping burrs, dimensional deviations, and mold damage caused by misalignment.

[0018] The degreasing mechanism 7 includes: a water tank 701, a guide rail 702, a material support plate 703, a first bevel gear 704, and a second threaded rod 705. The water tank 701 is fixedly connected to the front of the punch press body 2. The guide rail 702 is fixedly connected to the inner wall of the water tank 701. The material support plate 703 is slidably connected to the inner wall of the guide rail 702. The second threaded rod 705 is slidably connected to the inner wall of the lower die 4. The first bevel gear 704 is rotatably connected to the side of the lower die 4 near the water tank 701. The degreasing mechanism 7 also includes: a second bevel gear 706, a third threaded rod 707, an internal threaded sleeve 708, a connecting plate 709, and a stop block 710. The connecting plate 709 is fixedly connected to the side of the lower die 4 near the water tank 701. The third threaded rod 707 is rotatably connected to the inner wall of the connecting plate 709. The internal threaded sleeve 708 is rotatably connected to the inner wall of the connecting plate 709. The threaded rod 707 is dynamically connected to the circumferential surface of the threaded rod 707. The inner wall of the bevel gear 704 is threaded, and the thread on the inner wall of the bevel gear 704 is movably connected to the threaded rod 705. The internal threaded sleeve 708 is fixedly connected to the support plate 703. The bevel gear 704 and the bevel gear 706 mesh with each other to form a gear set. The inner wall of the guide rail 702 is equipped with an elastic telescopic component for resetting the support plate 703. It can remove stamping oil, metal shavings and other dirt from the surface of the workpiece, shorten the subsequent processing time and the overall production cycle. It can also prevent the workpiece from being contaminated with dust or oil in the environment during transportation or stacking. As the support plate 703 moves up and down, the dirt on the surface of the workpiece immersed in the cleaning solution is carried away with the flow of the cleaning solution, further improving the cleaning effect of the workpiece.

[0019] Working principle: After material discharge is completed, the conveyor belt 611 starts to transport the aluminum material to the lower die 4. The motor inside the support column 501 drives the mounting base 502 to rotate clockwise. The rotation of the mounting base 502 drives the connecting arm 504 to rotate. At this time, the L-shaped limiting plate 608 on the side of the connecting arm 504 away from the push plate 507 contacts and squeezes the push plate 603 to move forward. The forward movement of the push plate 603 drives the internal thread ring 613 to move. The movement of the internal thread ring 613 drives the thread rod 602 to rotate through the thread on its inner wall. The rotation of the thread rod 602 drives the spur gear 605 to rotate. The rotation of the spur gear 605 drives the rack 606 that meshes with it to move. The movement of the rack 606 drives the friction block 607 to move and contact the aluminum material, pushing the aluminum material out of the conveyor belt 611 to the stamping position of the lower die 4. The aluminum material is pushed out through the friction block 607. There is no need for frequent manual feeding, realizing the synchronous operation of stamping and feeding, reducing downtime. In conjunction with the discharge mechanism 5, a complete automated production line is formed, improving the overall production capacity. When the friction block 607 pushes the aluminum material to the stamping area of ​​the lower die 4, the aluminum material may bounce away due to collision with the L-shaped limiting plate 608 and fail to fully enter the stamping area of ​​the lower die 4. Therefore, after the friction block 607 pushes the aluminum material, the lifting and lowering rotating rod 609 is driven to fall by the motor inside the connecting arm 504, so that the friction wheel 610 contacts the aluminum material. Then, the electric motor on the inner wall of the lifting and lowering rotating rod 609 starts to drive the friction wheel 610 to rotate and rub against the aluminum material, so that the aluminum material is more closely attached to the L-shaped limiting plate 608. The position of the aluminum material is adjusted again by the friction wheel 610, which further improves the accuracy of the feeding mechanism 6 and ensures that the feeding position is aligned with the center of the die each time, avoiding stamping burrs, dimensional deviations and die damage caused by misalignment.

[0020] After stamping, the workpiece is pushed by the pusher plate 507 into the water tank 701 and falls onto the receiving plate 703. There, it comes into contact with the cleaning fluid in the water tank 701 to degrease the workpiece, removing stamping oil, metal shavings, and other contaminants from its surface. This shortens subsequent processing time and the overall production cycle, and also prevents the workpiece from becoming contaminated with dust or oil during transport or storage. When the connecting arm 504 moves forward, pushing the pusher plate 507 to push the workpiece out, the pusher plate 507 contacts and pushes the stop block 710 to move. The stop block 710 moves, causing the threaded rod 705 to move. The threaded rod 705, through its surface threads, drives the bevel gear 704 to rotate. The rotation of bevel gear 704 drives the meshing bevel gear 706 to rotate, which in turn drives the threaded rod 707 to rotate. The rotation of threaded rod 707 pushes the internal threaded sleeve 708 downward through its threads. The downward movement of the internal threaded sleeve 708 pushes the support plate 703 downward and stretches the elastic telescopic component installed on the inner wall of guide rail 702, immersing the pusher plate 507 and the workpiece in the cleaning fluid. As the pusher plate 507 moves back, the force of the elastic telescopic component resets the support plate 703. As the support plate 703 moves up and down, the dirt on the surface of the workpiece immersed in the cleaning fluid is carried away by the flow of the cleaning fluid, further improving the cleaning effect of the workpiece.
