Specific implementation mode

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

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

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

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

[0028] The robotic deburring machine and the CNC rotary flexible grinding machine use a high-precision vision recognition system to scan and position the surface of the casting, and then use special tools or grinding tools to accurately remove burrs according to the preset path and force. This can not only make the surface of the casting smooth and flat, but also increase the processing efficiency by dozens of times compared with the traditional method. Compared with the traditional deburring process that requires a large number of workers to grind for a long time, only a small number of technicians are needed for equipment maintenance and parameter monitoring, and the labor cost is greatly reduced.

[0029] Among them, the robotic deburring machine is made by segmenting robots.

[0030] By dividing the complete processing position of 180 seconds into 12 robots for deburring by the robotic deburring machine, the average deburring processing time per piece is shortened to 15 seconds - 30 seconds, saving 6 - 12 times the time compared with the original 180 seconds to process one product.

[0031] Among them, the rotary table of the CNC rotary flexible grinding machine takes 2 seconds to make one revolution.

[0032] For an ordinary single-workbench grinding machine, it takes 20 seconds to load the fixture for a product, 20 seconds to unload the fixture, 10 seconds to blow the workbench clean with an air gun, 130 seconds to process each product, 50 seconds for loading and unloading the fixture and blowing the workbench, and 480 products can be processed in 24 hours a day. While the CNC rotary flexible grinding machine can process 720 products in 24 hours a day, which is 1.5 times more efficient than the traditional single-workbench grinding machine in deburring.

[0033] Among them, the die-casting machine 1 uses a 650T squeeze casting machine.

[0034] The 650T squeeze casting machine realizes precise injection of magnesium-aluminum alloy solution, mold opening and closing, etc. through an automated robotic arm and a closed furnace pressure injection pump, ensuring that each casting process can be carried out strictly according to the preset parameters and charging, effectively avoiding process deviations caused by human factors, greatly improving the forming quality and dimensional accuracy of the castings. At the same time, it completely abandons the manual operation part in traditional high-pressure casting, greatly reducing the labor cost.

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

[0036] Traditional shot blasting machines are placed independently, dozens of meters away from the workstations, and forklifts are needed to transport products during use. While the CNC type shot blasting machine, through its application on the production line, shortens the non-working time and unnecessary personnel handling.

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

[0038] When using a traditional CNC cutting machine, it takes 20 seconds to load the fixture, 20 seconds to unload the fixture, and 10 seconds to blow the workbench clean with an air gun. While the vertical CNC775 automated rotary cutting machine can shorten 50 seconds for each product processing through the rotary workbench.

[0039] Among them, independent inspection items are set between each device.

[0040] The traditional inspection method is centralized inspection. There are a large number of products to be inspected, inspection items are prone to backlog, and it takes a long time. While by adjusting and distributing the inspection items to each device workstation, the inspection batch can be reduced, the inspection efficiency can be improved, and the use of labor can be reduced.

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

[0042] The ultrasonic waves of the ultrasonic dryer can generate high-frequency vibrations, causing the liquid molecules to have intense friction and collisions, thereby quickly generating heat and accelerating the evaporation process. This drying method is faster than the traditional drying method and the drying effect is more uniform, avoiding problems such as local overheating or uneven drying.

[0043] Working principle and usage process:

[0044] First, after the aluminum furnace 2 and magnesium furnace 3 have melted the raw materials, the dried raw materials are sent into the die-casting machine 1 by the dryer 10 for high-pressure die-casting. Subsequently, the die-cast products are sent to the deburring machine 4 by the AGV transport equipment 11 for deburring. Immediately afterwards, the products with burrs removed are transported to the friction stir welding machine 5 by the AGV transport equipment 11 for friction welding treatment. After the products are friction welded, the products are sent to the shot blasting machine 6 by the AGV transport equipment 11 for shot blasting. Then, the shot-blasted products are sent to the CNC cutting machine 7 by the AGV transport equipment 11 for cutting processing. Subsequently, the AGV transport equipment 11 will send the cut products to the cleaning machine 8 for high-pressure cleaning to remove impurities. Then, the AGV transport equipment 11 sends the cleaned products to the passivation machine 9 for passivation treatment. Finally, the passivated products are sent to the dryer 10 by the AGV transport equipment 11 for ultrasonic drying. Subsequently, the products can be sent to the warehouse for storage by the AGV transport equipment 11. In this way, the AGV transport equipment 11 can be used to replace the manual operations between each link, thereby effectively improving the processing efficiency of the magnesium-aluminum alloy production line, reducing labor costs. At the same time, the use of robotic deburring machines, CNC rotary flexible grinding machines, and vertical CNC 775 automated rotary cutting machines improves the processing efficiency of aluminum-magnesium alloys and reduces the number of guards. In addition, by distributing all the inspection items to each equipment station, the inspection batch can be reduced and the inspection efficiency can be improved.
