[0002] With the development of metallurgical manufacturing technology, segregation purification technology has become one of the main purification methods for producing high-purity aluminum. This technology can effectively improve the purity of metal materials and is widely used in the production process of high-purity aluminum. Its characteristic is that it can achieve efficient cooling and forming of metal materials by controlling the temperature and environment in the crucible.

[0003] After the crucible ingots produced by the segregation purification method cool and form, they need to be separated from the crucible. Traditionally, high-purity aluminum manufacturers have manually used a piercing tool to pierce the crucible ingot, creating a deep cylindrical hole for removal. However, the entire piercing process is labor-intensive, inefficient, and difficult to meet the needs of large-scale production. Furthermore, the operator must come into direct contact with the high-temperature crucible ingot, posing a safety hazard. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0044] The applicant noted that currently, high-purity aluminum manufacturers typically use manual piercing tools to pierce the ingot. The crucible containing the semi-molten ingot is manually hoisted onto a pourer, and the crucible is slowly tilted, allowing the molten aluminum to slowly flow out. The crucible is then tilted downward at a 175-degree angle and stopped, with the molten aluminum continuing to flow out. After the upper surface of the crucible ingot solidifies slightly, the piercing tool is manually poked into the center of the ingot. A pneumatic jackhammer is then used to push the piercing tool into the ingot, forming a cylindrical deep hole, and the piercing tool is then removed. However, manual piercing has poor quality consistency, and the operation poses a certain risk of splashing liquid aluminum.

[0045] See also Figure 1 , Figure 1 The schematic diagram of the structure of a hole-drilling device according to one embodiment of the present invention is shown. The hole-drilling device provided by one embodiment of the present invention includes a hole-drilling assembly, a feed mechanism 10, a swing mechanism 20, and a mounting bracket 30. The hole-drilling assembly is used to rotate and insert a crucible ingot; the feed mechanism 10 is connected to the hole-drilling assembly and is used to drive the hole-drilling assembly forward or backward; the swing mechanism 20 is disposed between the feed mechanism 10 and the hole-drilling assembly and is used to drive the hole-drilling assembly to reciprocate during the hole-drilling process; and the mounting bracket 30 is connected to the feed mechanism and the swing mechanism 20.

[0046] Specifically, the feeding mechanism 10 and the swinging mechanism 20 are fixed on the mounting bracket 30, and the hole-opening assembly is connected to the feeding mechanism 10. The feeding mechanism 10 drives the hole-opening assembly to move closer to or away from the crucible ingot. When the crucible is fixed in a preset position, the hole-opening assembly is aligned with the center of the crucible ingot. The feeding mechanism 10 drives the hole-opening assembly to move closer to the crucible ingot and causes the crucible ingot to penetrate into the crucible ingot, thereby forming a hole in the crucible ingot. The swinging mechanism 20 moves following the feeding mechanism 10 and is fixed on the mounting bracket 30. While the feeding mechanism 10 drives the hole-opening assembly to move closer to or away from the crucible ingot, it drives the hole-opening assembly to reciprocate in a direction perpendicular to the travel path, so that the size of the hole formed in the crucible ingot is slightly larger than the hole-opening assembly. When the hole-opening operation is completed, the swinging mechanism 20 stops moving, and the feeding mechanism 10 drives the hole-opening assembly away from the crucible ingot.

[0047] In this embodiment, the hole-opening component performs stable forward and backward motions driven by the feed mechanism 10, ensuring precise control of the hole-opening depth; the swing mechanism 20 further increases the flexibility of the hole-opening component, enabling it to achieve reciprocating motion during rotation, thereby effectively preventing the hole from being offset and ensuring the uniformity and flatness of the hole wall; ensuring the quality consistency of the hole-opening, greatly reducing the errors caused by human factors, and significantly improving the accuracy and surface quality of the hole-opening.

[0048] Please continue reading Figure 1 In some embodiments, the hole opening assembly includes an anchor rod 102 and an anchor head 104. The anchor rod 102 is cylindrical and connected to the feeding mechanism 10. The anchor head 104 is connected to the anchor rod 102, and the end of the anchor head 104 away from the anchor rod 102 is tapered.

[0049] Specifically, the first end 110110 of the anchor head is the end away from the anchor rod 102 and is tapered for insertion into the crucible ingot. The second end 112 of the anchor head is the end closer to the anchor rod 102 and is cylindrical with a diameter identical to the diameter of the tapered bottom surface of the first end of the anchor head 104. The anchor rod 102 is cylindrical and connected to the second end 112 of the anchor head. The diameter of the anchor rod 102 is smaller than the diameter of the second end of the anchor head 104.

[0050] For example, when the anchor head 104 is inserted into the crucible ingot, the swing mechanism 20 drives the anchor head 104 to reciprocate along the vertical direction of the travel path, forming a cylindrical opening in the crucible ingot. The swing mechanism 20 causes the second end 112 of the anchor head to extrude and trim the side wall of the opening, so that the diameter of the side wall of the opening is slightly larger than the diameter of the second end of the anchor head 104.

[0051] Optionally, the cone apex angle of the first end of the anchor head 104 is less than 30°, the anchor head 104 is made of nickel-cadmium alloy or titanium alloy, the anchor rod 102 is made of medium carbon steel, and the anchor head 104 is screwed to the anchor rod 102 .

[0052] In this embodiment, the first end 110110 of the anchor head is conical with a top angle of less than 30°, which facilitates smooth insertion into the crucible ingot. The second end 112 of the anchor head is cylindrical. Through the reciprocating motion of the swing mechanism 20, the anchor head 104 can form a precise cylindrical hole in the crucible ingot. The second end 112 of the anchor head extrude and trim the hole wall during the insertion process to ensure the flatness and dimensional accuracy of the hole wall, thereby improving the quality of the hole opening; the anchor head 104 is made of high-temperature resistant material, which also improves the durability and wear resistance of the anchor head 104.

[0053] Combine Figure 1 and Figure 2 As shown, Figure 2A schematic structural diagram of a hole opening assembly in an embodiment of the present invention is shown. In some embodiments, the hole opening assembly further includes a trimming member 106, which is sleeved at the connection between the anchor rod 102 and the anchor head 104 and is used to trim the surface area of the crucible ingot hole.

[0054] Specifically, the trimming piece 106 is sleeved on the anchor rod 102. The cross-section of the trimming piece 106 is T-shaped, and the vertical portion of the T-shape is tightly connected to the second end 112 of the anchor head. When the anchor head 104 is fully inserted into the crucible ingot, the vertical portion of the trimming piece 106 abuts against the upper surface of the crucible ingot. Since the anchor head 104 is inserted into the crucible ingot, a convex deformation is generated at the opening of the crucible ingot. The vertical portion of the trimming piece 106 rotates with the anchor head 104 and the anchor rod 102, and the vertical portion flattens the convexity of the crucible ingot and evenly spreads it on the upper surface of the crucible ingot. If the convexity on the upper surface of the crucible ingot is severe, the horizontal portion of the trimming piece 106 presses down on the convexity to avoid it. The vertical portion gradually flattens the convexity of the crucible ingot, and prevents excessive accumulation of convex material during the flattening process, which blocks the rotation of the opening assembly.

[0055] In this embodiment, the trimming piece 106 in the hole opening assembly can effectively trim the surface area of the crucible ingot hole. After the anchor head 104 is inserted into the crucible ingot, the trimming piece 106 rotates with the anchor head 104 to flatten the protrusions at the hole opening and evenly spread them on the upper surface of the crucible ingot. In the case of severe protrusions, the trimming piece 106 can also flatten the protrusions to prevent material accumulation, thereby ensuring a smooth and high-quality hole opening process and improving the flatness of the crucible ingot after the hole opening and the overall processing effect.

[0056] Please continue reading Figure 1 and Figure 3 , Figure 3 A side view of the hole-opening device in one embodiment of the present invention is shown. In some embodiments, the device further comprises a hammer mechanism 40 , which is disposed on the mounting bracket 30 and connected to the hole-opening assembly for hammering the hole-opening assembly to insert the crucible ingot.

[0057] Specifically, the hammer mechanism 40 includes a hammering member 402 and a rotating member. The hammering member 402 provides downward pressure on the hole-opening assembly, enabling the hole-opening assembly to be smoothly inserted into the crucible ingot. The first end of the hammering member 402 is connected to the swing mechanism 20, the second end of the hammering member 402 is connected to the first end of the rotating member, and the second end of the rotating member is connected to the hole-opening assembly. The rotating member drives the anchor rod 102 and the anchor head 104 to rotate. Optionally, the hammering mechanism 40 also includes a buffer portion; the hammering member 402 is connected to the swing mechanism 20 and the rotating member via a hammering bracket. The hammering member 402 hammers the front mechanism with high frequency and intermittently, buffering and absorbing the reaction force of the hammering. When the hole-opening device is performing a hole-opening operation on the crucible ingot, the anchor head 104 is simultaneously subjected to the downward pressure provided by the hammering member 402, the steering force provided by the rotating member, and the reciprocating motion driven by the swing mechanism 20. The hammering bracket prevents the swing mechanism 20 from affecting the hammering member 402 and the rotating member.

[0058] In this embodiment, the hammering mechanism 40 is mounted on a bracket and connected to the hole-opening assembly, providing downward pressure to help the hole-opening assembly be smoothly inserted into the crucible ingot; the hammering mechanism 40 cooperates with the hammering member 402 and the rotating member to enable the anchor rod 102 and the anchor head 104 to complete self-rotation while being subjected to downward pressure and steering force, and at the same time cooperates with the reciprocating motion of the swinging mechanism 20 to achieve efficient hole-opening operation; the hammering bracket effectively isolates the influence of the swinging mechanism 20 on the hammering member 402 and the rotating member, ensuring the stability of the entire operation and the accuracy of the hole-opening.

[0059] Please continue reading Figure 1 and Figure 3 In some embodiments, the mounting bracket 30 includes a slide rail 302, a rack 304, and an adjustment plate 306. The slide rail 302 is arranged along the travel direction of the opening assembly; the rack 304 is arranged parallel to the slide rail 302 and engages with the steering gear 116; the adjustment plate 306 is slidably connected to the slide rail 302 and connected to the steering gear 116. The steering gear 116 acts on the rack 304 to drive the adjustment plate 306 to move forward or backward along the slide rail 302.

[0060] Specifically, the feed mechanism 10 includes a driver 118 and a steering gear 116. The output end of the driver 118 is provided with an output gear that meshes with the steering gear 116. The steering gear 116 meshes with a rack 304 on the mounting bracket 30, converting the rotation of the driver 118 into a linear motion of the aperture assembly. The rack 304 is a long, metal piece with a row of evenly spaced teeth along one side. The rack 304 meshes with the teeth of the steering gear 116, converting the rotational motion of the driver 118 into linear motion of the rack 304. The mounting bracket 30 is a rectangular frame structure with its long sides aligned with the direction of travel of the aperture assembly. The slide rail 302 and the rack 304 are arranged parallel to the long sides of the mounting bracket 300, and an adjustment plate 306 is slidably connected to the slide rail 302. The feed mechanism 10, the swing mechanism 20, and the hammer mechanism 40 are fixed to the side of the adjustment plate 306 facing away from the slide rail 302. The feeding mechanism 10 drives the adjusting plate 306 to move along the slide rail 302 and drives the swing mechanism 20, the hammer mechanism 40 and the hole opening assembly to move synchronously. Optionally, the driving member 118 is a motor reducer.

[0061] Illustratively, the driving member 118 in the feeding mechanism 10 rotates, and the output gear at the output end of the driving member 118 engages the steering gear 116, transmitting the rotational motion to the steering gear 116. The steering gear 116 engages with the rack 304, converting the rotational motion of the driving member 118 into linear motion of the rack 304, thereby driving the adjustment plate 306 along the slide rail 302. When the hole opening assembly is to be moved away from the crucible ingot, the driving member 118 rotates, and the adjustment plate 306 drives the feeding mechanism 10, the swing mechanism 20, the hammer mechanism 40, and the hole opening assembly away from the crucible ingot.

[0062] In this embodiment, precise linear motion of the hole-opening assembly is achieved through the cooperation of the driving member 118 with the steering gear 116 and the rack 304; the swing mechanism 20, the hammer mechanism 40 and the hole-opening assembly work synchronously to ensure the stability and efficiency of the hole-opening operation; it can effectively reduce the difficulty of operation, improve work efficiency, and at the same time ensure the consistency of the hole-opening quality.

[0063] Please continue reading Figure 1 and Figure 3 In some embodiments, the swing mechanism 20 is a set of bidirectional swing cylinders 202 symmetrically arranged on both sides of the hammer mechanism 40 .

[0064] Specifically, the swing mechanism 20 is disposed between the feed mechanism 10 and the hammer mechanism 40. The swing mechanism 20 is indirectly connected to the feed mechanism 10 via an adjustment plate 306 and directly connected to the hammer mechanism 40. The swing mechanism 20 includes a transmission member 204 and two symmetrically arranged swing cylinders 202. The first surface of the transmission member 204 is fixedly connected to the adjustment plate 306, and the second surface of the transmission member 204 is fixedly connected to the hammer mechanism 40. Opposite surfaces of the transmission member 204 are respectively connected to the swing cylinders 202, which are symmetrically arranged about the central axis of the anchor rod 102. The two swing cylinders 202 exert force on the transmission member 204 at intervals, causing the transmission member 204 to drive the downstream components to reciprocate along the direction of travel of the anchor head 104.

[0065] Illustratively, when the anchor head 104 is about to be inserted into the crucible ingot, the hammering member 402 of the hammering mechanism 40 drives the anchor head 104 into the crucible ingot. The rotating member of the hammering mechanism 40 drives the anchor head 104 to slowly rotate during the hole drilling process. After reaching the drilling depth, the anchor head 104 rotates to trim the hole wall. The trimming member 106 corrects the surface of the crucible ingot. After the trimming is completed, the anchor head 104 is removed from the crucible ingot. Optionally, the anchor head 104 rotates more than two revolutions during the process of inserting the crucible ingot and trimming the hole.

[0066] In this embodiment, the two-way swing cylinders 202 are symmetrically arranged on both sides of the hammer mechanism 40, and the anchor head 104 is driven to reciprocate in the vertical direction of travel at staggered intervals. At the same time, the anchor head 104 rotates to insert the crucible ingot and rotates in the opposite direction to pull out the hole, thereby achieving the trimming of the inner wall and upper surface of the crucible ingot hole, thereby improving the hole quality and operation efficiency.

[0067] Please continue reading Figure 1 and Figure 3 In some embodiments, a heat insulating member 108 is further included. The heat insulating member 108 is cylindrical, and the diameter of the heat insulating member 108 is larger than the diameter of the anchor rod 102. The two ends of the heat insulating member 108 are respectively connected to the anchor rod 102 and the feeding mechanism 10.

[0068] Specifically, the thermal insulation member 108 includes a thermal insulation body and quick-connect flanges 114 at both ends of the thermal insulation body. The end of the anchor rod 102 away from the anchor rod 102 is also provided with a quick-connect flange 114. The quick-connect flange 114 at the end of the thermal insulation member 108 near the anchor rod 102 is screwed to the quick-connect flange 114 of the anchor rod 102, and the quick-connect flange 114 at the end of the thermal insulation member 108 away from the anchor rod 102 is connected to the hammer mechanism 40. The thermal insulation body is cylindrical, and the diameter of the thermal insulation body is larger than the diameter of the anchor rod 102. The thermal insulation body is a hollow frame. While maintaining sufficient rigidity, it reduces the heat transfer area and provides the pressure, steering force, and swing force provided by the hammer mechanism 40 and the swing mechanism 20 to the anchor head 104.

[0069] Illustratively, the steering gear 116 in the feed mechanism 10 converts the rotational motion of the drive member 118 into linear motion of the rack 304, thereby driving the adjustment plate 306 to move along the slide rail 302. The hole-drilling assembly approaches the crucible ingot, and the hammering mechanism inserts the anchor head 104 of the hole-drilling assembly into the crucible ingot to drill a hole. Simultaneously, the hammering mechanism also rotates the anchor head 104. When the anchor head 104 is inserted into the crucible ingot, the swinging mechanism 20 drives the anchor head 104 to reciprocate in a direction perpendicular to the travel path, forming a cylindrical hole in the crucible ingot. The rotating member of the hammering mechanism 40 drives the anchor head 104 to rotate slowly during the drilling process. After reaching the drilling depth, the anchor head 104 rotates to trim the hole wall. The trimming member 106 corrects the surface of the crucible ingot. After the trimming is completed, the anchor head 104 exits the crucible ingot, completing the drilling of the crucible ingot.

[0070] In this embodiment, the hole opening assembly and the hammer mechanism 40 are connected by the heat insulation member 108 to prevent the heat of the crucible ingot from being transferred to the hammer assembly through the hole opening assembly and causing deformation damage to the upstream mechanism, thereby increasing the service life of the hole opening device and reducing the equipment failure rate.
