Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy casting, in particular to a full-automatic casting island of gravity casting with a rotating station. BACKGROUND

[0002] The gravity casting process in aluminum alloy casting is a traditional and mature casting process, and its application range is extremely wide due to the advantages of easy control and stability, high product qualification rate, and low production cost. The casting products cover related parts in the automobile field, related parts in large and medium-sized equipment, and various products in many subdivided industries. At present, the application of gravity casting equipment is mainly based on a single gravity casting device, and the casting production is controlled by manual operation, which cannot effectively guarantee the key quality control means in the production process. Because there are too many manual participation links, the aluminum liquid pouring amount cannot be accurately controlled in each casting process, which leads to unstable product quality, low yield, and greatly increased production cost. At the same time, the special tool is needed to take out the casting blank by manual clamping, and the mold temperature loss is large due to the slow speed of manual taking, which causes the mold temperature to be unstable after secondary molding, affecting the quality of subsequent casting products, and further increasing the production cost due to the secondary heating of the mold. In the subsequent production process, the cooling of the casting blank after the casting process, the removal of the sprue, and other links are independent production modules, which cannot meet the continuity and efficiency of mass production. Because of the independence and discontinuity of production, a large amount of non-value-added logistics transportation and a large area of workshop site for product storage are occupied, which not only increases the production cost, but also reduces the effective utilization rate of the workshop production site. Due to the above-mentioned adverse factors, how to design a full-automatic casting island that can meet the requirements of efficient and mass production, ensure stable product quality, and realize the cooling and removal of the casting blank has become the biggest problem in the industry.

For example, steps two and three can be interchanged or performed in parallel. The invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 10 The fully automated casting island for gravity casting with a rotary station, as shown in one embodiment of the present invention, utilizes an automated aluminum melt casting system 200 ( Figure 3 ), Rotary table system 300 ( Figure 4 Gravity casting system 400 ( Figure 5 The three systems are flexibly combined, and with innovative process design, innovative equipment design and precise control system, the shortcomings of existing single-machine casting equipment in terms of production continuity and long production cycle are changed.

[0037] In one embodiment of the present application, the process workflow of one working cycle of the rotating intelligent aluminum alloy casting island is as follows: the operation of the whole production line equipment is controlled by the control system 900, and the production safety is controlled by the safety system 1000. The production line adds the treated aluminum liquid to the aluminum liquid supply system 100, at this time the casting island has the production raw materials. The aluminum liquid is taken out from the aluminum liquid supply system 100 by the automatic aluminum liquid pouring system 200 and added to the mold of the gravity casting system 400. The gravity casting system 400 is cyclically rotated by the rotating table system 300, and the gravity casting machine with poured aluminum liquid is rotated to the next station, and the gravity casting machine without poured aluminum liquid is rotated to the pouring station, and the aluminum liquid pouring is sequentially circulated to all the gravity casting machines contained in the gravity casting system 400. When the first poured gravity casting machine rotates to the discharging station, the casting blank picking, mold cavity cleaning and mesh placing system 500 picks the gravity casting machine, cleans the mold cavity and places the mesh, and places the casting to the casting blank forming quality detection and cooling system 700 for detection and cooling, and takes the mesh from the mesh supply system 600 for standby, and the previous casting cycle continues production. After the casting is cooled, the third intelligent robot 807 in the casting blank pouring gate cutting and material taking and placing system 800 takes the casting from the casting blank forming quality detection and cooling system 700 and places it in the oil press 801 for edge cutting treatment, and after the edge cutting treatment is completed, the third intelligent robot 807 takes the casting and places it in the material frame. As described above.

[0038] The aluminum liquid supply system 100 of the present application is shown in Figure 1 and Figure 2 : the furnace base 101 is fixed on the ground, the furnace positioning device 102, the heating busbar automatic plug-in device 103 and the with or without heat preservation furnace detection device 110 are installed on the furnace base 101, and the male busbar 109 is installed on the crucible heat preservation furnace 113. When the crucible heat preservation furnace 113 is replaced, the control system 900 sends a related control signal, at this time the fourth cylinder 106 in the heating busbar automatic plug-in device 103 drives the busbar 104 to move along the second sliding block sliding rail assembly 105, disconnects the connection between the busbar 104 and the male busbar 109, at this time the related heating and detection signals are disconnected, the crucible heat preservation furnace 113 has the condition of being removed, and the crucible heat preservation furnace 113 is removed by the transfer device for adding aluminum liquid. At this time, the pressing block 111 in the with or without heat preservation furnace detection device 110 is popped up, the limit switch 112 signal is closed, and the system detects that the crucible heat preservation furnace 113 has been removed.

[0039] When the ladle holding furnace 113 is returned to the original position by the transfer device after the liquid aluminum addition is completed, the ladle holding furnace 113 is positioned by the furnace positioning device 102, and then the ladle holding furnace 113 is lowered. At this time, the briquetting 111 is pressed down, the limit switch 112 signal is opened, the system detects that the ladle holding furnace 113 has been returned, the fourth cylinder 106 drives the female block 104 to move along the second sliding block rail assembly 105, the connection between the female block 104 and the male block 109 is closed, and the signals of the related heating and detection are all closed. In the production process, the temperature of the liquid aluminum in the ladle holding furnace 113 is detected by the stainless steel thermocouple assembly 108 and the liquid aluminum temperature detection device 107, so as to ensure the process temperature.

[0040] The specific embodiment of the automatic liquid aluminum casting system 200 of the present application is as follows: Figure 1 and Figure 3 As shown in the drawings: when the liquid aluminum is scooped, the first intelligent robot 201 moves to the upper end of the ladle holding furnace 113 with the quantitative casting manipulator 202 and the special scoop 203 made of, for example, ceramic. At this time, the quantitative casting manipulator 202 is in a vertical posture. The first intelligent robot 201 moves downward, and when the liquid aluminum surface detection device 204 detects the liquid aluminum surface, the movement is stopped. At this time, the liquid aluminum is scooped by tilting the special scoop 203. According to the different tilting angles, different amounts of liquid aluminum can be scooped. After the liquid aluminum is scooped, the first intelligent robot 201 moves to the gravity casting machine pouring position with the quantitative casting manipulator 202, and pours the liquid aluminum into the mold by tilting the special scoop 203. After pouring is completed, the first intelligent robot 201 moves to the upper end of the oxide skin cleaning device 205. At this time, it is detected that the special scoop 203 is located on the oxide skin cleaning device 205, the gas supply device 206 is opened, the residual oxide skin in the special scoop 203 is cleaned by the blowing head 207, the oxide skin falls into the waste frame 208, and after cleaning is completed, the first intelligent robot 201 moves to the upper end of the ladle holding furnace 113 to wait.

The positioning principle of the multi-station rotary table 301 is as follows: when it rotates to a specified predetermined position, the multi-station rotary table 301 stops rotating, at which time the first cylinder 308 in the rotary table positioning device 307 drives the insertion of the tongue 309 into the positioning insertion hole of the multi-station rotary table 301, and the multi-station rotary table 301 realizes accurate positioning. When the multi-station rotary table 301 needs to rotate, the first cylinder 308 drives the tongue 309 to be pulled out of the positioning insertion hole of the multi-station rotary table 301, at which time the multi-station rotary table 301 can rotate freely. As described above is the working cycle of the multi-station rotary table.

The positioning principle of the multi-station rotary table 301 is as follows: when it rotates to a specified predetermined position, the multi-station rotary table 301 stops rotating, at which time the first cylinder 308 in the rotary table positioning device 307 drives the insertion of the tongue 309 into the positioning insertion hole of the multi-station rotary table 301, and the multi-station rotary table 301 realizes accurate positioning. When the multi-station rotary table 301 needs to rotate, the first cylinder 308 drives the tongue 309 to be pulled out of the positioning insertion hole of the multi-station rotary table 301, at which time the multi-station rotary table 301 can rotate freely. As described above is the working cycle of the multi-station rotary table.

As described above is the working cycle of the multi-station rotary table.

[0043] When the gravity casting machine 401 needs to be pushed back to the multi-station rotary table 301, the gravity casting machine 401 is moved along the rail assembly 314 and the guide rail 325 by the driving motor 318 of the push-pull device 319, until the gravity casting machine 401 is in contact with the limiting block 315, at which time the second cylinder 311 drives the insertion of the pin 312 into the locking pin hole 409 of the transfer trolley 408, and the third cylinder 320 pulls out the pin 324 from the push-pull pin hole 410 of the transfer trolley 408, so that the gravity casting machine 401 is locked on the multi-station rotary table 301 by the gravity casting machine locking device 310, and the push-pull device 319 returns to the initial position.

[0044] As shown in Figure 4 : the central slip ring device 313 is installed in the center of the multi-station turntable 301, for realizing the transmission of water, gas, oil, electricity related medium between the rotating workbench system and the outside. Among them, the hydraulic system installed on the outside of the multi-station turntable 301 transmits hydraulic power to the multi-station turntable 301 through the central slip ring device 313, driving the action of the gravity casting machine 401.

[0045] The specific embodiment of the gravity casting system 400 of the present application is as follows: Figure 1 and Figure 5 : the gravity casting machine 401 of the gravity casting system 400 is installed on the multi-station turntable 301, and the hydraulic system 415 controlling its action is installed on the outside of the multi-station turntable 301.

[0046] As shown in Figure 5 , the mold cooling system 411 is composed of a control system and a flow control device, and is installed on the side of the gravity casting machine 401. When cooling the mold, the cooling water is distributed to each cooling channel through the water distributor 412, the opening and closing of each cooling channel is controlled through the opening and closing of the electrically controlled on-off valve 414, the specific flow of each cooling water is adjusted through the flow regulator 413, and the cooling of the mold is realized through the above implementation process.

[0047] The specific embodiment of the casting blank taking and mold cavity cleaning and mesh placing system 500 of the present application is as follows: Figure 6 As shown in : the multifunctional gripper 502 is installed at the shaft end of the second intelligent robot 501, when the gravity casting machine 401 is opened and rotated to the blanking station, the second intelligent robot 501 acts, moves the taking gripper 504 of the multifunctional gripper 502 to the grabbing point, the chuck cylinder 503 drives the taking gripper 504 to act and clamp the casting, and then takes away the casting. At this time, the second intelligent robot 501 rotates 180° through the six axes, blows and cleans the mold cavity through the blowing head 507, after cleaning, the chuck cylinder 506 drives the mesh taking gripper 505 to act, places the filter mesh at the specified position, and the second intelligent robot 501 carries the multifunctional gripper 502 to move to the subsequent station. As described above is the working embodiment of the casting blank taking and mold cavity cleaning and mesh placing system 500.

[0048] The specific embodiment of the mesh providing system 600 of the present application is as follows:Figure 6 and Figure 7 As shown in the figure: in the process of supplying the net, the operator pours the filter net 604 into the hopper of the vibration net supply device 601, and through the spiral vibration, the filter net 604 is arranged in order and transported to the net taking point 602.

As described above, it is the working implementation mode of the casting blank forming quality detection.

[0050] As shown in the figure: Figure 8 When the casting is placed on the positioning block 709 on the lifting platform 706, the lifting support 708 drives the casting to be immersed in water by driving the cylinder 707 along the vertical direction. After the casting is immersed in water for a process time, the lifting support 708 rises above the water surface. As described above, it is the working implementation mode of the cooling system to complete the cooling of the casting.

[0051] As shown in the figure: Figure 8As shown: Cooling water is stored in the main body of the water tank 701. The temperature of the cooling water is detected by a thermocouple 703, and the temperature data is fed back to the water temperature detection device 702. When the cooling water temperature rises to the upper limit of the process temperature, the control system sends a signal to open the electrically controlled on / off valve 705. The low-temperature cooling water enters the main body of the water tank 701 through the water supply device 704, while the higher-temperature water overflows from the tank. As the low-temperature cooling water enters, the water temperature in the main body of the water tank 701 drops. When the water temperature drops to the lower limit of the process temperature, the electrically controlled on / off valve 705 closes, and this cycle is repeated to control the cooling water temperature. The above describes the implementation method of the cooling system to control the water temperature.

[0052] Specific embodiments of the casting blank gating cut-off and material handling system 800 of the present invention are as follows: Figure 8 and Figure 9 As shown: The third intelligent robot 807, equipped with a multi-functional gripper 808, picks up the casting from the positioning block 709 and places it into the special mold of the hydraulic press 801 for edge trimming. After trimming, it removes the casting and places it into a designated material box. The process of picking up the casting from the positioning block 709 and placing it into the special mold is completed by the cylinder 811 driving the gripper 812. The process of removing the casting from the special mold is completed by the cylinder 809 driving the gripper 810. The above describes the working implementation of the material handling system.

[0053] like Figure 9 As shown: A dedicated trimming die is mounted on the hydraulic press 801, with the lower die mounted on the worktable 802 and the upper die mounted on the movable table 803. During the punching process, the main hydraulic cylinder 805 drives the movable table 803 to reciprocate up and down along the main guide rod 804, completing the punching process. The punched material falls directly into the receiving trolley 806. The above describes the implementation method for removing the gating system from a casting blank.

[0054] Specific implementation methods of the security system 1000 of the present invention: as follows Figure 10 As shown: The entire casting island is physically isolated by a safety fence 1001 to prevent personnel from entering the equipment operating area. Safety doors 1002 and 1003 are used for personnel access and are controlled by safety locks conforming to international safety standards. Safety bars 1004 and 1005 are used for safe passage control when the gravity casting machine 401 is being pulled at the maintenance station 317. During continuous production, if any safety trigger signal of the safety system 1000 is activated, the entire casting island will immediately stop operating to ensure personnel safety. The above describes the implementation method of the safety system.

[0058] The gravity casting system 400 adopts 1 set of system 5 machine linkage control, that is, one set of control system is adopted to realize the production of different types of products by each gravity casting machine 401 according to different formulas by complex logic control, and realize mixed-line efficient product production.

[0059] According to the central slip ring device 313 of the application, the control system and the hydraulic system of the gravity casting system 400 are placed outside the multi-station rotary table 301, which not only facilitates the maintenance and maintenance of the equipment, but also reduces the load and occupied space of the multi-station rotary table 301, effectively improves the system maintainability and space utilization.

The present application provides two sets of heat preservation furnaces, which meet the continuous supply of molten aluminum in the production process by alternating supply of molten aluminum. The rotating table system is used to carry the gravity casting machine and rotate according to the casting sequence and station requirements during the casting production process, so as to realize the continuous casting production, which is the core system of the casting island. The multi-station rotary table is used as the main structure, which is used to carry 5 gravity casting machines for rotating action. The rotary table driving device is driven by a frequency conversion motor as a power output to rotate the rotary table at a set speed, which is installed outside the rotary table. The rotary table positioning device is used for accurate positioning after the rotary table stops at the specified position, so as to ensure the position accuracy of the overall automatic operation, which is installed outside the rotary table. The maintenance station is used for mold replacement or equipment maintenance of the gravity casting machine on the rotary table, and the application of the maintenance station also ensures that any gravity casting machine on the rotary table needs to replace the mold or be maintained without stopping production activities, and only needs to be transported to the maintenance station, at which time the casting island can continue to produce continuously without interference. The casting island is provided with two maintenance stations, which are installed outside the rotary table. The gravity casting machine locking device is composed of a driving cylinder and a latch, which is installed on the rotary table and used for locking the gravity casting machine on the rotary table to prevent accidental movement. The track assembly is installed on the rotary table and used to carry the gravity casting machine.

[0061] The gravity casting system is a key equipment for casting production and realizing the shaping of molten aluminum. It includes a gravity casting machine, a transfer car, a mold cooling system, and a hydraulic system. The gravity casting machine, as the main body of the casting equipment, is composed of a main body, a moving table assembly, and a demolding device, which realizes the movement of the moving table and the demolding device through the driving of the hydraulic cylinder. The transfer car is a carrying and transporting car of the gravity casting machine, which is installed at the bottom of the vertical leg of the gravity casting machine and is used to realize the transfer of the gravity casting machine between the rotary table and the maintenance station. At the same time, the transfer car has a locking pin hole for positioning and locking the position of the gravity casting machine.
