Description

Technical Field

[0001] The utility model relates to a stamping equipment for aluminum alloy, in particular to an aluminum alloy stamping equipment applied to the technical field of aluminum profile processing. Background Art

[0002] With the rapid development of the manufacturing industry, aluminum alloy is widely used in the fields of automobiles, aerospace, electronic products, etc. due to its light weight, high strength, good electrical conductivity and corrosion resistance. Among them, the stamping process of aluminum alloy sheets is one of the key processes for manufacturing complex-shaped parts. Although traditional aluminum alloy stamping equipment can meet basic production requirements, it has limitations in terms of processing accuracy, production efficiency, die maintenance, and material utilization rate. Especially, it faces challenges in ensuring the surface quality of stamped parts and extending the die life.

[0003] On the one hand, the high-speed friction between the aluminum alloy sheet and the die during the stamping process will generate a large amount of heat, leading to local overheating of the material, affecting the dimensional accuracy and surface finish of the stamped parts. In severe cases, it may even cause uneven material deformation. On the other hand, die wear and stamping residual stress are likely to form burrs on the product surface, increasing the cost and time of subsequent deburring treatment. In addition, traditional equipment often neglects the automatic lubrication and cleaning system of the die, resulting in frequent die maintenance and affecting production continuity.

[0004] The specification of the Chinese utility model patent CN218310477U discloses an aluminum alloy profile stamping equipment, including a base. A L-shaped support plate is fixedly installed on the top of the base. A cylinder is fixedly installed on the inner wall of the top of the L-shaped support plate. Two first telescopic rods are fixedly installed on the inner wall of the top of the L-shaped support plate. A fixing mechanism for fixing the aluminum alloy profile is arranged on the base. The beneficial effect of the utility model is that by setting the fixing mechanism, the fixing plate first presses the aluminum alloy profile, and at the same time squeezes the spring, and the pressing block stamps the aluminum alloy profile, thus avoiding unqualified quality of the aluminum alloy profile stamping. If the aluminum alloy profile is short, the handle can be rotated to drive the corresponding bidirectional screw to rotate, and the two fixing plates are brought closer to each other through the belt, so as to facilitate stamping of aluminum alloy profiles with different lengths, better fix the aluminum alloy profile, and facilitate improving the stamping quality of the aluminum alloy profile.

[0032] The following will describe in detail two embodiments of the present application with reference to the accompanying drawings.

[0033] The first embodiment:

[0034] Figures 1-9 Shown.

[0035] An aluminum alloy stamping device includes an aluminum alloy plate 1. A backing plate 2 is in contact with the top end of the aluminum alloy plate 1. A through hole 3 is opened inside the backing plate 2. A cleaning ring 4 is fixedly connected to the inner end of the through hole 3. A plurality of lubricating holes 5 are opened inside the backing plate 2, and the lubricating holes 5 are distributed in a circumferential array around the axis of the backing plate 2. A lubricating ring 6 is opened inside the backing plate 2, and the lubricating holes 5 communicate with the lubricating ring 6. An oil inlet hole 7 is opened inside the backing plate 2. A hydraulic cylinder 8 is fixedly connected to the top end of the backing plate 2. A hydraulic rod 9 is slidably connected to the inner end of the hydraulic cylinder 8, and the hydraulic cylinder 8 communicates with the oil inlet hole 7 through a pipeline. An oil delivery pipe is fixedly connected to the outer end of the hydraulic cylinder 8. The end of the oil delivery pipe is fixedly connected to an oil tank 10. A check valve 11 is fixedly connected to the outer end of the oil delivery pipe. An annular groove 12 is opened in the backing plate 2 corresponding to the position of the cleaning ring 4. An oil drain hole 13 is opened in the backing plate 2 corresponding to the position of the annular groove 12, and the oil drain hole 13 communicates with the annular groove 12. The oil drain hole 13 communicates with the oil tank 10 through a pipeline. A core sleeve 14 is slidably connected to the inner end of the through hole 3. A first return spring 15 is slidably connected to the outer wall of the core sleeve 14. The bottom end of the core sleeve 14 is fixedly connected to the top end of the hydraulic rod 9.

[0036] The backing plate 2 is located at the top of the aluminum alloy plate 1. Structures such as a through hole 3, a lubricating hole 5, a lubricating ring 6, and an oil inlet hole 7 are provided inside the backing plate 2. The through hole 3 facilitates the passage of the core sleeve 14. The lubricating holes 5 evenly distributed around the axis of the backing plate 2 contribute to more uniform lubrication of the core sleeve 14. The lubricating holes 5 communicate with the lubricating ring 6 to form an efficient automatic lubrication system. The lubricating oil can significantly reduce the friction coefficient between the core sleeve 14 and the aluminum alloy plate 1, reduce the resistance during the stamping process, reduce the force required for stamping, prevent the material from adhering to the die, improve the smoothness and efficiency of stamping, reduce the heat generated by friction and uneven deformation, thereby improving the dimensional accuracy, surface finish, and overall quality of the stamped parts, reducing the generation of burrs and scratches. A cleaning ring 4 is installed inside the through hole 3, and the cleaning ring 4 will clean the residual burrs on the core sleeve 14. Removing the burrs on the core sleeve 14 can ensure the surface quality of the stamped parts. The connection between the hydraulic cylinder 8 and the oil inlet hole 7 enables the lubricating oil to smoothly enter the lubricating ring 6. The hydraulic rod 9 is in contact with the core sleeve 14, enabling the core sleeve 14 to drive the action of the hydraulic cylinder 8 for lubrication operations. The application of the first return spring 15 ensures that the core sleeve 14 can quickly return to its original position when there is no pressure, improving the continuity and efficiency of the operation. The fuel tank 10 is used to store hydraulic oil. The oil pipeline and the one-way valve 11 ensure the smoothness and safety of the oil circulation, prevent backflow, protect the hydraulic system from pollution and damage, and improve the stability and reliability of the system. The annular groove 12 and the oil drain hole 13 help collect and discharge the waste oil or impurities generated during use, keep the inside of the equipment clean, and at the same time, through the pipeline connected to the fuel tank 10, achieve the effective recovery of waste oil, which is both environmentally friendly and economical.

[0037] The second embodiment:

[0038] Figures 1-9 shown.

[0039] The inner end of the core sleeve 14 is slidably connected to a core 16. The outer wall of the core 16 is slidably connected to an upper die base 17. The top of the core 16 is fixedly connected to a press 18. The bottom of the upper die base 17 is fixedly connected to a plurality of guide posts 19, and the plurality of guide posts 19 are evenly distributed at the four corners of the upper die base 17.

[0040] The bottom of the backing plate 2 is in contact with a female die 20. The inner end of the female die 20 is slidably connected to an anti - ejector rod 21. The bottom of the anti - ejector rod 21 is fixedly connected to a guide plate 22.

[0041] The top of the guide plate 22 is fixedly connected to a plurality of ejector rods 23. The ejector rods 23 pass through the backing plate 2 and are slidably connected to the backing plate 2. The ejector rods 23 pass through the female die 20 and are slidably connected to the female die 20. The top of the ejector rods 23 is in contact with the bottom of the core sleeve 14.

[0042] A plurality of limiting blocks 24 are fixedly connected to the top end of the ejector rod 23, and the limiting blocks 24 are symmetrically arranged. A second return spring 25 is slidably connected to the outer wall of the ejector rod 23.

[0043] The bottom end of the guide post 19 is fixedly connected to the lower die base 26, and the lower die base 26 abuts against the second return spring 25. The guide post 19 passes through the female die 20 and is fixedly connected to the female die 20. The guide post 19 passes through the backing plate 2 and is fixedly connected to the backing plate 2. The hydraulic rod 9 of the aluminum alloy plate 1 passes through the core sleeve 14 and is slidably connected to the core sleeve 14.

[0044] The cleaning ring 4 is made of high-density polyethylene material and is added with a composite anti-aging agent containing an ultraviolet absorber and an antioxidant. The cleaning ring 4 is connected to the through hole 3 in an embedded manner.

[0045] A plurality of cooling channels 27 are formed inside the female die 20, and an electromagnetic induction coil 28 is fixedly connected inside the female die 20.

[0046] The inner end of the core sleeve 14 is slidably connected to the core 16. Cooperating with the press 18, an accurate forming unit is formed, which improves the processing flexibility and precision. The multi-guide posts 19 at the bottom end of the upper die base 17 are evenly distributed, enhancing the stability and centering of the upper and lower parts of the die, ensuring the perpendicularity and uniform force during the stamping process, and improving the product quality and production efficiency. During stamping, the anti-ejector rod 21 moves downward synchronously with the core sleeve 14, and can evenly apply pressure around the hole to prevent the aluminum alloy plate 1 from overflowing to one side or flowing unevenly during the stamping process, thereby controlling the flow of the edge material and reducing the curling phenomenon. After the unloading is completed in one stamping, the first return spring 15 makes the core sleeve 14 return to the initial position, and the second return spring 25 makes the anti-ejector rod 21 and the guide plate 22 return to the initial position. The limiting block 24 makes the anti-ejector rod 21 flush with the female die 20. The cleaning ring 4 made of high-density polyethylene is not only wear-resistant and corrosion-resistant, but also can effectively extend the service life. The embedded connection method simplifies the maintenance and replacement process. The design of the cooling channels 27 and the electromagnetic induction coil 28 inside the female die 20 respectively realizes the efficient cooling and annealing functions of the die, which has a significant effect on controlling the temperature during the forming process, improving the material fluidity, shortening the cooling time, and improving the production efficiency.

[0047] During the actual use process, the working process of this equipment is as follows:

[0048] Use the automatic feeding device to feed the aluminum alloy plate 1 into the die, energize 29, and preheat the aluminum alloy plate 1 using the induction heating principle. Preheat the aluminum alloy plate 1 and the die components to ensure that the aluminum alloy plate 1 reaches the ideal processing temperature before stamping. Preheating can reduce the yield strength and tensile strength of the material, making the material flow more easily during the stamping process, reducing deformation and improving the forming quality.

[0049] After preheating is completed, the press 18 is started. The press 18 drives the core 16 to move downward along the inner wall of the upper die base 17. When the core 16 moves to a predetermined position, the core 16 drives the core sleeve 14 to continue moving downward to stamp the aluminum alloy plate 1. The first return spring 15 is compressed and contracted. While the core sleeve 14 stamps and cuts the aluminum alloy plate 1, the core sleeve 14 drives the ejector rod 23 to move downward, and the ejector rod 23 drives the guide plate 22 to move downward synchronously. The second return spring 25 is compressed and contracts downward. At the same time, the guide plate 22 drives the reverse ejector rod 21 to move downward to complete the stamping. The initial position of the reverse ejector rod 21 contacts the bottom end of the aluminum alloy plate 1 and is flush with the female die 20. During stamping, it moves downward synchronously with the core sleeve 14, and can evenly apply pressure around the hole to prevent the aluminum alloy plate 1 from overflowing to one side or having uneven flow during the stamping process, thereby controlling the flow of the edge material and reducing the curling phenomenon. Secondly, the movement of the core sleeve 14 activates the lubrication device to clean and lubricate the core sleeve 14. After one stamping is completed and the material is unloaded, the press 18 drives the core 16 to move upward. The core sleeve 14 returns to the initial position under the resilience of the first return spring 15. At the same time, the second return spring 25 rebounds, causing the reverse ejector rod 21 and the guide plate 22 to return to the initial position. Due to the limitation of the limit block 24, the reverse ejector rod 21 is flush with the female die 20. At this time, one stamping stroke is completed.

[0050] During stamping, when the core sleeve 14 moves downward, the core sleeve 14 presses against the hydraulic rod 9, causing the hydraulic rod 9 to move downward along the inner wall of the hydraulic cylinder 8, pressing the lubricating oil into the lubricating ring 6 through the pipeline, and then entering the oil inlet hole 7 through the lubricating ring 6 to lubricate the core sleeve 14. Since the one-way valve 11 is provided on the oil inlet pipe, it ensures that the lubricating oil will not flow back into the fuel tank 10. The excess lubricating oil flows downward along the outer wall of the core sleeve 14 and is absorbed by the cleaning ring 4. The lubricating oil absorbed by the cleaning ring 4 flows into the annular groove 12 and finally returns to the fuel tank 10 through the oil drain hole 13 for recycling. At the same time, during the reciprocating movement of the core sleeve 14, the cleaning ring 4 will also clean the residual burrs on the core sleeve 14. Removing the burrs on the core sleeve 14 can ensure the surface quality of the stamped parts, avoid the transfer of burrs to the workpiece during stamping, thereby obtaining a smoother and more beautiful product surface, reducing the subsequent deburring process, improving the overall yield, cleaning the burrs on the core sleeve 14 helps to maintain the sharpness of the die edge, extend the service life of the die, cleaning the burrs can keep the die operating smoothly, and improve the stability and efficiency of the stamping process.

[0051] After one stamping is completed and the material is unloaded, the press 18 drives the core 16 to move upward. The core sleeve 14 returns to the initial position under the resilience of the first return spring 15. At the same time, the second return spring 25 rebounds, causing the reverse ejector rod 21 and the guide plate 22 to return to the initial position. Due to the limitation of the limit block 24, the reverse ejector rod 21 is flush with the female die 20. At this time, one stamping stroke is completed.

[0052] After the stamping parts are formed, annealing treatment is required to eliminate internal stress and maintain stable material properties. At this time, induction heating annealing can be carried out through the electromagnetic induction coil 28 inside the female die 20. After annealing, rapid or controllable cooling is carried out in cooperation with the cooling channel 27 to ensure stable material structure and prevent deformation. Annealing helps to reduce surface defects caused by internal stress, improve the dimensional stability and service performance of parts. An appropriate cooling rate helps to stabilize the dimensions of aluminum alloy stamping parts and reduce deformation caused by the redistribution of internal stress in the material during the cooling process.

[0053] Combined with the current actual requirements, the above implementation methods adopted in this application, the scope of protection is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
