[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, this utility model provides a high-efficiency, low-cost production line for high-pressure casting of magnesium-aluminum alloys, including a die-casting machine 1, an aluminum furnace 2 and a magnesium furnace 3 respectively arranged on the left and right sides in front of the die-casting machine 1, a deburring machine 4 respectively arranged on the right side of the die-casting machine 1 and the magnesium furnace 3, a friction stir welding machine 5 arranged on the right side of the deburring machine 4, a shot blasting machine 6 arranged on the right side of the friction stir welding machine 5, a CNC cutting machine 7 arranged on the right side of the shot blasting machine 6, and a cleaning machine 8 arranged on the right side of the CNC cutting machine 7. A passivation machine 9 is located to the right of 8. A dryer 10 is located to the right of the passivation machine 9. AGV transport equipment 11 is located between the die casting machine 1 and the aluminum furnace 2 and magnesium furnace 3, between the die casting machine 1 and the deburring machine 4, between the deburring machine 4 and the friction stir welding machine 5, between the friction stir welding machine 5 and the shot blasting machine 6, between the shot blasting machine 6 and the CNC cutting machine 7, between the CNC cutting machine 7 and the cleaning machine 8, between the cleaning machine 8 and the passivation machine 9, between the passivation machine 9 and the dryer 10, and to the right of the dryer 10.

[0026] After the raw materials are smelted in aluminum furnace 2 and magnesium furnace 3, they are fed into die-casting machine 1 for high-pressure die casting via dryer 10. After die casting, the die-cast products are transported to deburring machine 4 via AGV transport equipment 11 for deburring. After deburring by AGV transport equipment 11, the products are transported to friction stir welding machine 5 for friction welding via AGV transport equipment 11. Then, the products processed by friction stir welding machine 5 are transported to shot blasting machine 6 via AGV transport equipment 11 for shot blasting. Finally, the shot-blasted products are transported to CNC cutting machine 7 via AGV transport equipment 11. After the CNC cutting machine 7 finishes processing, the product is transported to the cleaning machine 8 for cleaning via the AGV transport equipment 11. Then, the product is transported to the passivation machine 9 for passivation pretreatment via the AGV transport equipment 11. After the passivation treatment is completed, the product is transported to the dryer 10 for drying via the AGV transport equipment 11. Finally, the dried product is transported to the warehouse for storage via the AGV transport equipment 11. In this way, the AGV transport equipment 11 can replace manual operations between each link, thereby effectively improving the processing efficiency of the magnesium-aluminum alloy production line and reducing labor costs.

[0027] Among them, the deburring machine 4 includes a robotic deburring machine and a CNC rotary flexible grinder.

[0028] Robotic deburring machines and CNC rotary flexible grinding machines utilize a high-precision vision recognition system to scan and position the surface of castings. Then, using specialized tools or grinding tools, burrs are precisely removed according to a preset path and force. This not only makes the surface of the castings smooth and flat, but also increases the processing efficiency by dozens of times compared to traditional methods. Compared to the traditional deburring process, which requires a lot of manual labor for a long time, only a few technicians are needed for equipment maintenance and parameter monitoring, significantly reducing labor costs.

[0029] Among them, the robotic deburring machine is manufactured in sections by robots.

[0030] By dividing the 180-second processing time of a complete deburring station into 12 robots, the average deburring time per piece is reduced to 15-30 seconds, saving 6-12 times the time compared to the original 180 seconds to process one product.

[0031] Among them, the CNC rotary flexible grinder's rotary worktable takes 2 seconds to complete one revolution.

[0032] A typical single-table grinder takes 20 seconds to clamp the product, 20 seconds to unclamp it, and 10 seconds to clean the worktable with an air gun, for a total processing time of 130 seconds per product. The air gun takes 50 seconds to clean the worktable from the clamps, and the grinder processes 480 products per day in 24 hours. In contrast, a CNC rotary flexible grinder can process 720 products per day in 24 hours, which is 1.5 times more efficient than the traditional single-table grinder for deburring.

[0033] Among them, die casting machine 1 adopts a 650T squeeze casting machine.

[0034] The 650T extrusion casting machine uses an automated robotic arm and a closed furnace pressure injection pump to achieve precise injection of magnesium-aluminum alloy solution and mold opening and closing operations. This ensures that each casting process is carried out strictly according to preset parameters and is billed accordingly. It effectively avoids process deviations caused by human factors, greatly improves the forming quality and dimensional accuracy of castings, and completely eliminates the manual operation part in traditional high pressure casting, greatly reducing labor costs.

[0035] Among them, shot blasting machine 6 is a CNC shot blasting machine.

[0036] Traditional shot blasting machines are placed independently, dozens of meters away from the workstation, and require forklifts to transport products during use. However, CNC shot blasting machines, through their application on an assembly line, shorten non-working time and reduce unnecessary personnel handling.

[0037] Among them, CNC cutting machine 7 is a vertical CNC775 automated rotary cutting machine.

[0038] Traditional CNC cutting machines require 20 seconds to clamp the upper fixture, 20 seconds to clamp the lower fixture, and 10 seconds to clean the worktable with an air gun. However, the vertical CNC775 automated rotary cutting machine can reduce the time by 50 seconds per product processing by rotating the worktable.

[0039] Each device has its own independent testing items.

[0040] Traditional testing methods involve centralized testing, which results in a large number of products to be tested, a backlog of testing items, and long testing times. However, by adjusting and distributing testing items to various equipment stations, the testing batch size can be reduced, testing efficiency can be improved, and manual labor can be reduced.

[0041] Among them, the dryer 10 is an ultrasonic dryer.

[0042] Ultrasonic dryers use ultrasonic waves to generate high-frequency vibrations, causing liquid molecules to rub and collide violently, thereby quickly generating heat and accelerating the evaporation process. This drying method is faster and more uniform than traditional drying methods, avoiding problems such as local overheating or uneven drying.

[0043] Working principle and usage process of this utility model:

[0044] First, after the aluminum furnace 2 and magnesium furnace 3 have smelted the raw materials, the smelted raw materials are sent to the die-casting machine 1 for high-pressure die casting via the dryer 10. Then, the die-cast products are sent to the deburring machine 4 via the AGV transport equipment 11 for deburring. Next, the deburred products are transported to the friction stir welding machine 5 via the AGV transport equipment 11 for friction welding. After the friction welding is completed, the products are sent to the shot blasting machine 6 via the AGV transport equipment 11 for shot blasting. Then, the shot-blasted products are sent to the CNC cutting machine 7 via the AGV transport equipment 11 for cutting. Finally, the cutting products are sent to the cleaning machine 8 for high-pressure cleaning to remove impurities. After cleaning, the products are sent to the passivation machine 9 for passivation treatment. Finally, the passivated products are transported to the dryer 10 for ultrasonic drying via AGV transport equipment 11. Afterward, they can be leveled and transported to the warehouse for storage via AGV transport equipment 11. In this way, AGV transport equipment 11 can replace manual operations between each link, thereby effectively improving the processing efficiency of the magnesium-aluminum alloy production line and reducing labor costs. At the same time, the use of robotic deburring machines, CNC rotary flexible grinding machines, and vertical CNC775 automated rotary cutting machines improves the processing efficiency of aluminum-magnesium alloys and reduces the number of guards. In addition, by distributing all inspection items to various equipment stations, the number of inspection batches can be reduced and the inspection efficiency can be improved.
