Description

Technical Field

[0001] The utility model relates to the technical field of cast aluminum alloy crystallizers, in particular to a cast aluminum alloy crystallizer maintenance device. Background Art

[0002] A cast aluminum alloy crystallizer is a key piece of equipment for the crystallization and forming of deep-well cast aluminum alloy bars. The crystallizer is a trough-shaped container with a smooth inner wall. A transition sleeve is connected to the trough and fitted with a graphite ring. Water holes are evenly distributed around the graphite ring. During casting, molten aluminum flows from the transition sleeve into the crystallizer trough, where it gradually cools and crystallizes under the influence of cooling water. The aluminum is then formed and released from the mold as it passes through the graphite ring. Therefore, the crystallizer plays a crucial role in the appearance quality of the bar.

[0003] However, before casting, it is often necessary to dismantle the problematic crystallizer to maintain and replace the crystallizer water eye, adapter sleeve and graphite ring. During the disassembly and installation process, the crystallizer is often deformed due to stress due to falling. At the same time, when the plate with the crystallizer is lowered and connected to the casting machine base, the crystallizer is often deformed due to the tilting and misalignment of the ingot head on the base. The deformed crystallizer is difficult to repair and may even be directly scrapped due to the difficulty in repairing, resulting in increased labor costs and production costs. Utility Model Content

[0004] The purpose of the utility model is to provide a casting aluminum alloy crystallizer maintenance device, which can simply and quickly complete the repair and correction work of the deformed crystallizer, improve the repair efficiency, extend the service life of the crystallizer, and save the production cost of deep well casting aluminum alloy production enterprises.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Example 1

[0024] A cast aluminum alloy crystallizer maintenance device includes a support body 1 and a support screw; the support body 1 is a hollow frame structure, and the top of the support body 1 is an arc that fits the inner side of the crystallizer 6; the outer side of the support body 1 has a plurality of support clamps 2 for supporting in the crystallizer 6, and the top of the support clamp 2 extends to the outside of the top of the support body 1; the support screw can move longitudinally along the support body 1, and one end of the support screw penetrates into the interior of the support body 1, and the other end is located on the outside of the support body 1.

[0025] Working Principle: It should be noted that the inner diameter of the supporting body 1 is much smaller than the inner diameter of the crystallizer 6, and the sum of the length of the supporting screw and the height of the supporting body 1 is greater than the inner diameter of the crystallizer 6. When in use, the supporting screw is moved toward the inner cavity of the supporting body so that the supporting body 1 can be placed into the crystallizer 6, and the top of the supporting body 1 or the bottom of the supporting screw is placed at the deformed part of the crystallizer 6.

[0026] Then, the bottom of the supporting screw is moved downward so that the top of the supporting body 1 abuts against the inner wall of the top of the crystallizer 6 and the bottom of the supporting screw abuts against the inner wall of the bottom of the crystallizer 6. The supporting screw is continued to be moved downward. As the supporting screw is moved and tightened, the combined force of the top of the supporting body 1 and the tail of the supporting screw can restore the deformed part of the crystallizer 6 to its original shape.

[0027] When the device needs to be taken out, the supporting screw is moved toward the inner cavity of the supporting body, so that the overall height of the device of the utility model can be reduced, thereby smoothly taking it out from the crystallizer 6 and obtaining the repaired crystallizer 6.

[0028] Preferably, there are multiple support clamps 2, and they are evenly distributed on the outer surface of the supporting body 1. Specifically in this embodiment, there are three support clamps 2. The three support clamps 2 are supported in the threaded gap inside the crystallizer 6 to provide fixed support for the device of the utility model on the crystallizer 6, so as to prevent the device from falling into the crystallizer 6 during adjustment.

[0029] In this embodiment, the supporting screw has a support block 52 at one end located on the outside of the supporting body 1, and the support block 52 and one side of the crystallizer 6 are in an arc shape that fits with the inner side of the crystallizer 6; in this way, the contact area with the inner side of the crystallizer 6 is larger, the fixation is more stable, and the restoration effect of the deformed part of the crystallizer 6 is better.

[0030] In this embodiment, a positioning sleeve 4 is provided on the bottom frame of the supporting body 1 in the longitudinal direction; the supporting screw includes two independent first screws 3 and second screws 5, the first screw 3 extends into the interior of the supporting body 1, and the second screw 5 extends to the outside of the supporting body 1; and the ends of the first screw 3 and the second screw 5 that are close to each other are respectively sleeved in the positioning sleeve 4 and can move longitudinally along the positioning sleeve 4; and the first screw 3 and the second screw 5 are respectively provided with a first fastening nut 31 and a second fastening nut 51;

[0031] Specifically, during use, when it needs to be placed in the crystallizer 6, the overall height of the device is reduced, and the second screw 5 can be pushed upward to move upward in the positioning sleeve 4. At the same time, the first screw 3 can also be moved upward to release more movement paths for the second screw 5. When the device can be placed in the crystallizer 6, the first fastening nut 31 on the first screw 3 can be tightened to fix the position of the first screw 3. Then, after the second screw 5 is moved downward to a suitable position, the second fastening nut 51 can be tightened. As the second fastening nut 51 is tightened, the combined force of the top of the support body 1 and the tail of the support screw can restore the deformed part of the crystallizer 6.

[0032] In this embodiment, the length of the first screw 3 does not exceed the height of the internal cavity of the supporting body 1; thus, the up and down movement of the first screw 3 can be carried out in the internal cavity of the supporting body 1, thereby releasing more movement space for the longitudinal movement of the second screw 5 in the positioning sleeve 4.

[0033] In this embodiment, the outer side surfaces of the supporting body 1 and the supporting block 52 are both provided with anti-slip structures, such as threaded teeth, so that they can be well embedded with the inner wall of the crystallizer 6 to avoid sliding, making it more stable and reliable to use.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
