Description

Technical Field

[0001] This invention relates to the field of aluminum ingot casting technology, and more specifically to a gate removal device for aluminum ingot casting. Background Technology

[0002] Aluminum ingots are the basic product in the aluminum industry, widely used in aerospace, transportation, construction, packaging, and power electronics, among other fields. In the traditional casting process, molten aluminum is poured into a mold cavity through a gating system, and after cooling and solidification, it forms an aluminum ingot casting with residual parts of the gating system (commonly known as "gates" or "risers"). At the junctions of these gates and the casting body, as well as at the mold parting surface, casting defects such as flash and burrs often occur. These excess parts not only affect the appearance regularity of the aluminum ingot product, but if not removed, they may also scratch equipment or other aluminum ingot surfaces during subsequent transportation, stacking, and further processing, and even affect the precise proportions and quality stability of subsequent smelting or processing. Therefore, gate removal and flash cleaning are indispensable key processes after aluminum ingot casting.

[0003] Traditional gate removal and edge cleaning rely heavily on manual labor, where workers use tools such as chisels, hammers, or hand-held grinding wheels to tap and grind. This method is not only labor-intensive and inefficient, but also creates a harsh working environment with potential safety hazards. Furthermore, the consistency of quality in manual operations is difficult to guarantee, and uneven force or judgment errors can easily lead to ingot damage or incomplete cleaning.

[0004] To improve automation, some mechanized processing solutions have emerged in existing technologies, such as setting fixed grinding tools on the side of the conveyor line to grind aluminum ingots during transport. However, aluminum ingots are prone to positional shifts during transport, resulting in inconsistent postures when entering the grinding station, affecting grinding accuracy and consistency, and potentially causing equipment interference or processing failure due to positional deviations.

[0005] Therefore, it is necessary to design a gate removal device for aluminum ingot casting with automatic centering function to ensure grinding accuracy and efficiency. Summary of the Invention

[0006] A gate removal device for aluminum ingot casting includes a chain conveyor, a rectangular vertical conveying mechanism, a bracket, a U-shaped frame, a V-shaped frame, a return spring, and a grinding brush. The rectangular vertical conveying mechanism is symmetrically arranged on both sides of the chain conveyor. A bracket is arranged on the side of the rectangular vertical conveying mechanism facing the chain conveyor. A U-shaped frame is fixedly connected to the bottom of the bracket. A V-shaped frame is slidably arranged on the U-shaped frame, with the inner wall of the V-shaped frame slidingly engaging with the outer wall of the bracket. The V-shaped frame guides the aluminum ingot casting body into the bracket. Return springs are sleeved on the two U-shaped arms of the U-shaped frame, with both ends of the return springs connected to the bottom of the V-shaped frame and the bottom of the U-shaped frame, respectively. A grinding brush is provided on the rectangular vertical conveying mechanism for grinding the top edge of the aluminum ingot casting body. The rectangular vertical conveying mechanism drives the bracket upward to carry the aluminum ingot casting body away from the chain conveyor and transport it to the grinding brush for grinding.

[0007] Optionally, the rectangular vertical conveying mechanism includes a side frame, a sprocket assembly, a conveyor chain, a vertical guide rod, a first limiting block, and a connecting rod. The side frame is fixedly installed on the outer wall of the chain conveyor along its length. Two sets of sprocket assemblies are symmetrically arranged on the upper and lower sides of the side frame. Each sprocket assembly includes at least two sprockets arranged in parallel. A conveyor chain meshes between the sprocket assemblies. A connecting rod is fixedly connected to the side of the conveyor chain facing the chain conveyor. Vertical guide rods are arranged on both longitudinal sides of the side frame. A first limiting block is slidably arranged between the vertical guide rods. A limiting groove is opened on the first limiting block. One end of the bracket extends into the limiting groove and moves relative to the limiting groove. The end of the connecting rod away from the conveyor chain is fixedly connected to the bracket.

[0008] Optionally, a squeezing plate is provided on one side of the V-shaped frame near the chain conveyor, and horizontal guide rods are provided on both the upper and lower sides of the side frame. A U-shaped frame is slidably arranged between the horizontal guide rods, and an L-shaped blocking rod is symmetrically arranged on the side of the U-shaped frame facing away from the side frame. When the squeezing plate moves upward with the V-shaped frame to abut against the L-shaped blocking rod, the L-shaped blocking rod blocks the V-shaped frame from moving upward through the squeezing plate.

[0009] Optionally, the spacing between the openings of the V-shaped frame is greater than or equal to 1.5 times the width of the aluminum ingot casting body.

[0010] Optionally, a rack and a rotating shaft are provided on the lower part of the V-shaped frame facing away from the extrusion plate. The rotating shaft and the rack are at the same height. Slightly toothed gears are fixedly provided at both ends of the rotating shaft. The teeth of the slightly toothed gears can mesh with the teeth of the rack. The number of teeth on the toothed part of the slightly toothed gears is equal to the number of effective teeth of the rack that mesh with the V-shaped frame during its upward or downward movement. A second limiting block is fixedly installed on the shaft. When the second limiting block rotates upward with the rotating shaft and passes through the bracket, it abuts against the end of the aluminum ingot casting body in the width direction to limit and fix it from the width direction of the aluminum ingot casting body.

[0011] Optionally, a reinforcing block is symmetrically arranged on the missing gear with its teeth as the center, and the outer contour of the reinforcing block slides in contact with a pre-set guide surface on the V-shaped frame.

[0012] Optionally, the polishing brush includes two long brushes and two short brushes. The two long brushes are first polishing brushes that are rotatably arranged in parallel between the two side frames. The first polishing brushes are used to polish the two edges of the top surface of the aluminum ingot casting body in the length direction. The two short brushes are second polishing brushes that are rotatably arranged on the top of the two side frames respectively. The second polishing brushes are arranged between the two first polishing brushes. The second polishing brushes are used to polish the two edges of the top surface of the aluminum ingot casting body in the width direction.

[0013] Optionally, a protective cover is provided between the two side frames, the protective cover being positioned above the polishing brush and covering the polishing brush.

[0014] Optionally, a collection plate is provided on the outer wall and inner side of the chain conveyor along its length. The collection plate is located below the cleaning brush. A collection frame is designed on one side of the chain conveyor along its width, and the collection plate is inclined downward toward the collection frame.

[0015] Optionally, a positioning detection camera for monitoring and positioning the travel position of the aluminum ingot casting body and a controller for controlling the operation of the rectangular vertical conveying mechanism are installed on the side frame, and the positioning detection camera and the controller are electrically connected.

[0016] The beneficial effects of the present invention are: 1. The rectangular vertical conveying mechanism drives the bracket and V-shaped frame to move upward to carry the aluminum ingot casting body away from the chain conveyor, thereby picking up the aluminum ingot casting body. The aluminum ingot casting body slides down along the inner wall of the V-shaped frame to the center position of the bracket, realizing the automatic centering of the aluminum ingot casting body during the picking process, laying the foundation for subsequent precise grinding.

[0017] 2. The edges of the aluminum ingot casting body in the length and width directions are effectively ground by two first grinding brushes and two second grinding brushes, which has the advantages of high grinding efficiency and comprehensive treatment.

[0018] 3. The L-shaped blocking rod and the extrusion plate work together to effectively block the V-shaped frame from rising, thereby preventing the V-shaped frame from affecting the grinding work of the first and second grinding brushes; in addition, the second limiting block is driven to rotate by the cooperation of the rack and pinion, thereby completing the clamping and limiting of the end of the aluminum ingot casting body in the width direction.

[0019] 4. During the grinding operation, the debris and dust splashed down onto the collection plate by the protective cover, and then guided into the collection frame by the collection plate for collection, thus realizing the automatic collection and cleaning of waste. Attached Figure Description

Detailed Implementation

[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] Example: A gate removal device for aluminum ingot casting, such as Figures 1-5As shown, the assembly includes a chain conveyor 1, a rectangular vertical conveying mechanism 2, a bracket 3, a U-shaped frame 4, a V-shaped frame 5, a return spring 6, and a grinding brush. The rectangular vertical conveying mechanism 2 is symmetrically arranged on the two outer walls along the length of the chain conveyor 1. A bracket 3 is located on the side of the rectangular vertical conveying mechanism 2 facing the chain conveyor 1. A U-shaped frame 4 is fixedly connected to the bottom of the bracket 3. A V-shaped frame 5 is slidably arranged on the U-shaped frame 4. A vertical groove is formed on the outer wall of the bracket 3, and the V-shaped frame 5 moves along the vertical groove of the bracket 3. The lifting motion involves the V-shaped frame 5 guiding the aluminum ingot casting body 100 into the bracket 3. The two U-shaped arms of the U-shaped frame 4 are fitted with return springs 6, with the two ends of the return springs 6 connected to the bottom of the V-shaped frame 5 and the bottom of the U-shaped frame 4, respectively. The rectangular vertical conveying mechanism 2 is equipped with a grinding brush for grinding the top edge of the aluminum ingot casting body 100. The rectangular vertical conveying mechanism 2 drives the bracket 3 to move upward to carry the aluminum ingot casting body 100 away from the chain conveyor 1 and transport it to the grinding brush for grinding.

[0032] like Figure 2As shown, the rectangular vertical conveying mechanism 2 includes a side frame 201, a sprocket assembly 202, a conveyor chain 203, a vertical guide rod 204, a first limiting block 205, and a connecting rod 206. The side frame 201 is fixedly installed on the outer wall of the chain conveyor 1 along its length. Two sets of sprocket assemblies 202 are symmetrically arranged on the upper and lower sides of the side frame 201. Each set of sprocket assemblies 202 includes at least two sprockets arranged side by side. The conveyor chain 203 meshes between the sprocket assemblies 202. A connecting rod 206 is fixedly connected to the side of the conveyor chain 203 facing the chain conveyor 1. Vertical guide rods 204 are provided on both longitudinal sides of the side frame 201. A first limiting block 205 is slidably arranged between 04. A limiting groove 2051 is opened on the first limiting block 205. One end of the bracket 3 extends into the limiting groove 2051 and moves relative to the limiting groove 2051. The end of the connecting rod 206 away from the conveyor chain 203 is fixedly connected to the bracket 3. A drive motor (not shown in the figure) is provided on the side frame 201. The output shaft of the drive motor is connected to a sprocket. The drive motor is used to drive the sprocket to rotate so that the conveyor chain 203 moves. The conveyor chain 203 drives the bracket 3 to move horizontally along the limiting groove 2051 through the connecting rod 206 and to move up and down along the vertical guide rod 204 through the first limiting block 205. The spacing between the openings of the V-shaped frame 5 is greater than or equal to 1.5 times the width of the aluminum ingot casting body 100. When one end of the aluminum ingot casting body 100 enters the opening of the V-shaped frame 5 on one side, while the other end does not, the speed of the drive motors on both sides is controlled to drive the horizontal movement of the brackets 3 and V-shaped frame 5 along the limiting groove 2051, thereby ensuring that both ends of the aluminum ingot casting body 100 after displacement can also enter the opening of the V-shaped frame 5. The horizontal movement of the brackets 3 on both sides is controlled by controlling the rotation speed of the drive motors on both sides, gradually shifting and centering the aluminum ingot casting body 100. Then, the upward movement is performed, and the V-shaped frame 5 guides the aluminum ingot casting body 100 onto the bracket 3 through its V-shaped inner wall, thereby picking up the aluminum ingot casting body 100.

[0033] like Figures 4-6 As shown, a pressing plate 7 is provided on one side of the V-shaped frame 5 near the chain conveyor 1. Horizontal guide rods 8 are provided on both the upper and lower sides of the side frame 201. A U-shaped frame 91 is slidably arranged between the horizontal guide rods 8. An L-shaped blocking rod 92 is symmetrically arranged on the side of the U-shaped frame 91 facing away from the side frame 201. When the pressing plate 7 moves upward with the V-shaped frame 5 and comes into contact with the L-shaped blocking rod 92, the L-shaped blocking rod 92 blocks the V-shaped frame 5 from moving upward through the pressing plate 7. This ensures that the top surface of the V-shaped frame 5 is not higher than the top surface of the bracket 3, thereby preventing the V-shaped frame 5 from affecting the grinding operation of the grinding brush on the aluminum ingot casting body 100.

[0034] like Figures 5-7As shown, a rack 51 and a rotating shaft 10 are provided on the lower part of the V-shaped frame 5 facing away from the extrusion plate 7. The rotating shaft 10 and the rack 51 are at the same height. Gears 11 are fixedly provided at both ends of the rotating shaft 10. The teeth of the gears 11 can mesh with the teeth of the rack 51. The ratio of the central angles of the toothed part and the toothless part of the circumference of the gears 11 is 1:3. The number of teeth on the toothed part of the gears 11 is equal to the number of effective teeth of the rack 51 that mesh with the V-shaped frame 5 during the upward or downward movement, so as to ensure that the gears 11 can rotate 90 degrees in one complete meshing process. A second limiting block 12 is fixedly installed on the rotating shaft 10. When the second limiting block 12 rotates upward with the rotating shaft 10 and passes through the bracket 3, it abuts against the end of the aluminum ingot casting body 100 in the width direction, so as to limit and fix it from the width direction of the aluminum ingot casting body 100.

[0035] like Figure 6 and Figure 7 As shown, a reinforcing block 13 is symmetrically arranged on the missing gear 11 with its teeth as the center. The outer contour of the reinforcing block 13 slides in cooperation with the guide surface preset on the V-shaped frame 5. It is used to radially guide the missing gear 11 during the meshing or disengagement of the missing gear 11 and the rack 51 to ensure smooth meshing and prevent gear deflection.

[0036] like Figure 8As shown, the polishing brush includes two long brushes and two short brushes. The two long brushes are first polishing brushes 14, which are rotatably arranged in parallel between the two side frames 201. The two ends of the first polishing brushes 14 are fixedly mounted on the inner side walls of the two side frames 201 through bearing seats. A drive motor for driving the first polishing brushes 14 to rotate around their own axis is mounted on the side frame 201. The first polishing brushes 14 are used to polish the two edges of the top surface of the aluminum ingot casting body 100 in the length direction. The two short brushes are second polishing brushes 15, which are rotatably arranged on the top of the two side frames 201 respectively. The second polishing brushes 15 are fixedly arranged between the two first polishing brushes 14 through bearing seats. The second polishing brushes 15 are rotatably mounted on the bearing seats. The second polishing brushes 15 are used to polish the two edges of the top surface of the aluminum ingot casting body 100 in the width direction. A drive motor for driving the second polishing brushes 15 to rotate around their own axis is mounted on the side frame 201. In use, the brushes are polished by using a rectangular... When the vertical conveying mechanism 2 raises the aluminum ingot casting body 100 to its highest point, the first grinding brush 14 on one side contacts one edge of the aluminum ingot casting body 100 along its length direction, thereby grinding one edge of the aluminum ingot casting body 100 along its length direction. As the rectangular vertical conveying mechanism 2 drives the aluminum ingot casting body 100 to move horizontally at the highest point, the second grinding brushes 15 on both sides grind the edges of the aluminum ingot casting body 100 along its width direction. When the other edge of the aluminum ingot casting body 100 along its length direction moves to another first grinding brush 14, the first grinding brush 14 grinds the other edge of the aluminum ingot casting body 100 along its length direction. This achieves effective grinding of both sides of the aluminum ingot casting body 100 along its length and both sides along its width. After grinding is completed, the rectangular vertical conveying mechanism 2 drives the aluminum ingot casting body 100 to descend and reset.

[0037] like Figure 1 As shown, a protective cover 16 is provided between the two side frames 201. The protective cover 16 is located above the polishing brush and covers the polishing brush.

[0038] like Figure 1 and Figure 9 As shown, the outer wall and inner side of the chain conveyor 1 along the length direction are provided with a collection plate 17. The collection plate 17 is located below the cleaning brush. A collection frame 18 is designed on one side of the chain conveyor 1 along the width direction. The collection plate 17 is inclined downward towards the collection frame 18.

[0039] A positioning detection camera 19 for monitoring the movement and positioning of the aluminum ingot casting body 100, and a controller for controlling the operation of the rectangular vertical conveyor mechanism 2 are installed on the side frame 201. The positioning detection camera 19 is electrically connected to the controller. The positioning detection camera 19 continuously monitors the positioning status of the aluminum ingot casting body 100 and transmits the signal to the controller. The controller then precisely controls the start, stop, and operating rhythm of the rectangular vertical conveyor mechanism 2. When the positioning detection camera 19 detects that both ends of the aluminum ingot casting body 100 have entered the flared openings of the corresponding V-shaped frame 5, the positioning detection camera 19 sends a signal to the controller. After receiving the signal, the controller starts the drive motor and controls the rectangular vertical conveyor mechanism 2 to execute a fixed cycle program of lifting, horizontal movement, lowering, and horizontal reset.

[0040] The finished aluminum ingot casting body 100 is horizontally conveyed by the chain conveyor 1. When both ends of the aluminum ingot casting body 100 enter the flared openings of the corresponding V-shaped frame 5, the rectangular vertical conveying mechanism 2 is activated, thereby driving the bracket 3 and the V-shaped frame 5 to move upward, thus taking the aluminum ingot casting body 100 away from the chain conveyor 1. Under the action of gravity, the aluminum ingot casting body 100 slides down the inner wall of the V-shaped frame 5 to the center position of the bracket 3, achieving automatic centering and positioning. As the bracket 3 and the V-shaped frame 5 continue to rise, when the extrusion plate 7 contacts the L-shaped blocking rod 92, the L-shaped blocking rod 92 prevents the extrusion plate 7 from moving further upward, thereby stopping the V-shaped frame 5 from rising. At this time, the bracket 3 continues to rise under the drive of the rectangular vertical conveying mechanism 2, the return spring 6 is compressed, and at the same time, the rotating shaft 10, the missing gear 11, and the second limiting block 12 move upward with the bracket 3. During this process, the missing gear 11 rotates upward along the rack 51, driving the rotating shaft 10 and the second limiting block 12 fixed on the rotating shaft 10 to rotate. The second limiting block 12 rotates upward and passes through the bracket 3, abutting against the end of the aluminum ingot casting body 100 in the width direction located in the bracket 3, thereby clamping and fixing the aluminum ingot casting body 100 in the width direction. When the aluminum ingot casting body 100 is conveyed upward to the first grinding brush 14, the first grinding brush 14 grinds the edge of the aluminum ingot casting body 100 in the length direction, and the second grinding brush 15 grinds the edge of the aluminum ingot casting body 100 in the width direction to remove the burrs and flash on the top edge of the aluminum ingot casting body 100; the debris and dust generated during the grinding process are blocked by the protective cover 16 and fall downward onto the inclined collection plate 17 under the action of gravity, and finally slide into the collection frame 18, realizing the automatic collection of waste and keeping the working environment clean. After the edge processing of the aluminum ingot casting body 100 is completed, the rectangular vertical conveying mechanism 2 drives the bracket 3 to reset downwards. When the extrusion plate 7 descends away from the L-shaped blocking bar 92, the rack 51 on the V-shaped frame 5 drives the missing gear 11 to rotate in the opposite direction, causing the second limit block 12 to rotate downwards and leave the aluminum ingot casting body 100, thereby releasing the aluminum ingot casting body 100. When the aluminum ingot casting body 100 descends to the conveying plane of the chain conveyor 1, as the bracket 3 and the V-shaped frame 5 continue to move downwards, the aluminum ingot casting body 100 separates from the bracket 3 and is conveyed by the chain conveyor 1 to the next processing platform, completing one work cycle.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
