Description

Technical Field

[0001] The present invention relates to the technical field of sacrificial anodes, and in particular to an automatic casting production line for sacrificial anodes. Background Art

[0002] Currently, sacrificial anode protection has become a widely used anti-corrosion method, effectively protecting metal components in soil, freshwater, and marine environments. Because sacrificial anodes require an embedded cathode steel core, the casting process is more challenging than other coreless products. Furthermore, due to the wide variety of application environments, sacrificial anodes come in a wide variety of types and specifications, varying in size and weight. Furthermore, due to the high temperatures and harsh working conditions in production workshops, the casting and molding of sacrificial anodes is currently mostly manual.

[0003] However, manual operation often requires a large number of operators, and the production efficiency of manual molds or traditional casting machines is very low, and product quality cannot be guaranteed. In addition, while requiring high skills from workers, it also has a high risk factor. In actual use, safety accidents such as burns, fires and even explosions caused by operator negligence or equipment failure often occur.

[0004] While there are a small number of semi-automatic or fully automatic machines on the market, most are complex and lack practicality. Specifically, these machines have numerous gas, oil, and electrical circuits, resulting in high manufacturing and maintenance costs. Furthermore, they have long specification change cycles and are designed only for high-volume production of specific specifications, failing to meet current demands for diverse, small-batch, and customized products.

[0005] In summary, there is an urgent need in this field to develop a new type of sacrificial anode automated casting production line to meet practical use. Summary of the Invention

[0006] The purpose of the present invention is to provide an automated sacrificial anode casting production line to solve the following technical problems: the existing manual casting and molding methods have the problems of high labor costs, low production efficiency, high risk factors, and unguaranteed product quality, and there is a lack of relatively mature automated equipment on the market that can meet actual usage needs.

[0007] The present invention is achieved by adopting the following technical solutions:

[0008] A sacrificial anode automated casting production line includes a molding mechanism, a casting mechanism and a pickup mechanism are respectively provided on the periphery of the molding mechanism, and the molding mechanism, the casting mechanism and the pickup mechanism are respectively electrically connected to a control mechanism; wherein the molding mechanism includes a casting turntable, on which are provided several molding devices, and the casting turntable is connected to a cathode steel core mounting device.

[0009] In this production line, the pouring mechanism is used to extract the alloy melt and pour it into the molding mechanism, the molding mechanism is used to mold the melt to form a casting, the pickup mechanism is used to take out the casting and pass it to the next process, and the control mechanism is used to remotely control the operation of the molding mechanism, the pouring mechanism and the pickup mechanism, thereby realizing the automated operation of the equipment; based on this, this production line eliminates the need for complicated manual operations, has the advantages of safety, reliability, and simplified production lines, can realize continuous casting operations, and thus effectively improve operating efficiency and ensure product quality. Among them, in the molding mechanism, the pouring turntable provides a base surface and power for the molding device, can link the molding device to open and close the mold, and can realize the simultaneous operation of multiple molding devices; the molding device is used to directly perform die molding on the melt, and several molding devices on the pouring turntable can be installed with different molds respectively, so that products of different specifications can be processed; the cathode steel core installation device is used to fix the cathode steel core in the molding device.

[0010] Furthermore, the pouring mechanism includes a furnace connected to a liquid separation bag via a quantitative pump.

[0011] In the pouring mechanism, the furnace is used to form the melt, and the metering pump can extract the melt inside and transport it to the liquid separation bag, which is used to pour the melt into the molding device. The metering pump can ensure that the volume of the melt transported to the liquid separation bag each time is consistent, that is, the volume of the melt poured into the molding device is quantitative, so it can be ensured that the melt extracted each time just meets the requirements of the molding casting, thereby ensuring the filling quality of the product, while improving material utilization and reducing waste.

[0012] Furthermore, the pickup mechanism includes a pickup robot, and a conveyor belt is provided on one side of the pickup robot.

[0013] In the picking mechanism, a gripper is provided at the end of the picking robot's mechanical arm. The gripper can grab the castings in the molding device and place the castings into the conveyor belt one by one, which will be transported to the next process. The use of the picking robot has largely liberated manpower, accelerated the picking efficiency, and effectively reduced the risk of personnel coming into contact with high-temperature castings.

[0014] Furthermore, the casting turntable includes a turntable base, an integrated eccentric boss is provided above the turntable base, the turntable base is also connected to the disc through a bearing, the large gear disc connected below the disc is engaged with the drive device, and an ejection device is also provided below the disc.

[0015] Furthermore, a plurality of positioning switches are provided on the outer surface of the disc, and an ejection port is provided on the disc inside each positioning switch.

[0016] Furthermore, a forming device is provided at the ejection port, the forming device includes a fixed seat provided on the disc, the fixed seat is connected to a movable seat slidably connected to the disc through a guide column, and a mold is provided between the fixed seat and the movable seat.

[0017] Furthermore, the mold includes a fixed mold and a movable mold, and the fixed mold and the movable mold are respectively arranged on two adjacent surfaces of the fixed seat and the movable seat.

[0018] Furthermore, the two ends of the guide column pass through the fixed seat and the movable seat respectively, and a spring and an adjusting nut are provided in sequence on the part of the guide column extending out of the movable seat. One end of the rolling connecting rod is connected to the side of the movable seat away from the fixed seat, and the other end of the rolling connecting rod is connected to the eccentric boss.

[0019] Furthermore, the cathode steel core installation device is used to place the cathode steel core into the forming device, and the cathode steel core installation device includes a plurality of cathode steel core silos, and detection switches and installation components are provided on the outside of the plurality of cathode steel core silos.

[0020] The beneficial effects achieved by the present invention are:

[0021] A sacrificial anode automated casting production line can remotely control the operation of a molding mechanism, a pouring mechanism, and a retrieval mechanism through a control mechanism, thereby realizing automated melt conveying, pouring, molding, steel core placement, and retrieval of castings. Compared with existing manual pouring and molding operations, and automated equipment with complex structures and low practicality, the present invention can effectively improve production efficiency, shorten casting cycles, reduce production and maintenance costs, alleviate labor intensity, simplify on-site layout, and improve product quality while ensuring safety.

[0032] The cathode steel core installation device 27 includes a plurality of cathode steel core silos. Detection switches and installation components are provided on the outside of the plurality of cathode steel core silos. The installation components include a stopper, a positioning cylinder and a clamping cylinder.

[0033] The pouring mechanism includes a furnace 28, connected to a liquid dispensing bag 30 via a metering pump 29. The dispensing bag 30 is located above the molding device 8. The retrieval mechanism includes a retrieval robot 31, with a conveyor belt 32 attached to one side. A control mechanism 33 is located away from the high-temperature hazardous operating area (i.e., the casting turntable 1 and the molten aluminum). It is equipped with an emergency stop button and surrounded by explosion-proof observation windows. A protective fence surrounds the high-temperature production line consisting of the pouring mechanism, molding mechanism, and retrieval mechanism.

[0034] The working principle of this embodiment is as follows:

[0035] In this production line, the pouring mechanism is used to extract the alloy melt and pour it into the molding mechanism, that is, the metering pump 29 extracts the melt in the furnace 28 and transports it to the liquid separation bag 30, and the liquid separation bag 30 pours the melt into the molding mechanism; the molding mechanism is used to mold the melt to form a casting. Specifically, the pouring turntable 1 provides a base surface and power for the molding device 8, and can link the molding device 8 to open and close the mold to realize the molding of the melt by the molding device 8. The cathode steel core installation device 27 is used to fix the cathode steel core in the molding device 8; the control mechanism 33 is used to remotely control the operation of the molding mechanism, pouring mechanism and retrieval mechanism, thereby realizing the automatic operation of the equipment. Specifically:

[0036] After the driving device 7 is started, it can engage the transmission gear plate 6, thereby causing the disc 4 to rotate 360°; since the center positions of the disc 4 and the eccentric boss 5 are inconsistent, and the eccentric boss 5 and the turntable base 2 are an integrated structure, when the disc 4 rotates, the eccentric boss 5 will not move; the fixed frame will rotate with the disc 4 with the fixed seat 11, and the fixed seat 11 is transmitted to the movable seat 14 through the guide column 12, so that the movable seat 14 also rotates synchronously with the disc 4, so that the roller 23 at one end of the main traction rod 2120 slides in a circular shape along the inner surface of the eccentric boss 5, that is, the connection point between the roller 23 and the inner surface of the eccentric boss ring makes a circular motion; under the circular motion, the distance between the connection point and the center of the eccentric boss 5 is always constant, but its distance from the center of the disc 4 will continue to change. Therefore, relative to the initial position of the connection point, after the disc 4 starts to rotate, when the connection point continues to approach the center of the disc 4, it means that the roller 23 continues to approach the center of the disc 4, so the roller 23 will transmit the main traction rod 2120 to move the movable seat 14 continuously inward along the guide column 12, that is, the movable mold 19 moves with the movable seat 14, so that the distance between the movable mold 19 and the fixed mold 18 becomes larger, that is, the mold opening is completed; until the connection point begins to move away from the center of the disc 4, it means that the roller 23 begins to move away from the center of the disc 4, the inward pulling of the main traction rod 2120 on the movable seat 14 will continue to decrease, and under the elastic force of the spring 15, the movable seat 14 will move outward along the guide column 12, that is, the distance between the movable mold 19 and the fixed mold 18 continues to decrease, and the mold closing is gradually completed.

[0037] The positioning switch 25 indicates the position of the corresponding mold. When a molding unit 8 reaches directly above the ejection device 24, the ejection port of that molding unit 8 is also directly above the ejection device 24. At this point, the positioning switch 25 feeds this information back to the control mechanism 33, which then controls the ejection device 24 to eject the finished casting, facilitating its removal by the retrieval robot 31. In the molding unit 8, the lubricating oil cup 17 on the guide sleeve 16 lubricates the guide post 12 to reduce friction as the movable seat 14 slides along it, ensuring smooth movement and protecting the bearing surface. The spring 15 can be adjusted by adjusting the force of the adjusting nut, which propels the movable seat 14 toward the fixed seat 11. It is important to note that the molding unit 8 and the casting turntable 1 utilize a keyed quick-lock connection. Therefore, if the mold in the molding unit 8 is replaced off-line, the molding unit 8 can be quickly replaced within 5 minutes without disrupting normal production.

[0038] The cathode steel core installation device 27 is used for placing the steel core. When the detection switch detects the mold, the positioning cylinder pushes the steel core in the cathode steel core hopper to the mold position, the clamping cylinder is released, and the cathode steel core enters the mold.

[0039] The working process of this embodiment is as follows:

[0040] When the pouring turntable 1 rotates and the molding device 8 opens the mold, the steel core is installed in the mold through the cathode steel core installation device 27; when the mold is closed, the metering pump 29 extracts the melt from the furnace 28 and transports it to the position of the liquid separation bag 30, and the liquid separation bag 30 randomly pours the melt into the molding device 8 for molding; after molding is completed, as the mold opens and with the help of the indication of the positioning switch 25, the ejection device 24 ejects the casting; the picking robot 31 grabs the ejected casting and places the casting on the conveyor belt 32 for the next step of circulation.

[0041] To sum up, this production line can remotely control the molding mechanism, pouring mechanism and retrieval mechanism through the control mechanism 33 to realize the automatic melt conveying, pouring, molding, steel core placement and retrieval of castings; compared with the existing manual pouring and molding operation methods, and automated equipment with complex structures and low practicality, the present invention can effectively improve production efficiency, shorten the casting cycle, reduce production and maintenance costs, reduce labor intensity, simplify on-site layout and improve product quality while ensuring safety.

[0042] Of course, the above contents are only preferred embodiments of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples. Equivalent changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent of the present invention.
