Detailed Implementation

[0039] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] Example

[0042] like Figures 1-5 As shown, a spool-raising device for copper rod production includes a frame 1, with a crystallizing wheel 41 rotatably mounted in the middle of the frame 1; the crystallizing wheel 41 rotates uniformly on the surface of the frame 1 via a drive mechanism built into the frame 1.

[0043] The first adjusting component 31 is fixedly mounted on the frame 1 by an L-shaped fixing plate 311 and is located on one side of the crystallizing wheel 41; specifically, the first adjusting component 31 is located at the end of the copper block of the crystallizing wheel 41.

[0044] The first adjusting member 31 includes a main cylinder 316, which is fixedly installed on an L-shaped fixing plate 311. A sliding cylinder 317 is slidably arranged inside the main cylinder 316. One end of the sliding cylinder 317 is fixedly connected to the rotating sleeve 331, and the other end is provided with a threaded sleeve 3172. A threaded hole is provided in the middle of the threaded sleeve 3172.

[0045] A base plate 312 extends from one side of the upright plate of the L-shaped fixing plate 311, and a supporting bearing seat 313 is provided on the base plate 312. A drive rod 314 passes through both the L-shaped fixing plate 311 and the supporting bearing seat 313. The drive rod 314 includes a smooth section 3141 and a threaded section 3142. The threaded section 3142 is helically connected to a threaded sleeve 3172, controlling the sliding cylinder 317 to slide along the interior of the main cylinder 316. Specifically, when the drive rod 314 rotates, it only rotates on its own axis and does not produce radial displacement. Since the threaded section 3142 is threadedly connected to the threaded sleeve 3172, when the threaded section 3142 rotates, it pushes the sliding cylinder 317 to move along the channel of the main cylinder 316, thereby controlling the ingot lifting assembly 33 to move axially along the main cylinder 316.

[0046] To further control the movement of the sliding cylinder 317, a sliding limiting groove 3171 is formed by a recess in the middle surface of the sliding cylinder 317, and the length of the main cylinder 316 is less than the length of the sliding limiting groove 3171. To facilitate control of the drive rod 314, a rotating handle 315 is provided at the head end of the drive rod 314. A protective cover 34 is also provided on the outside of the first adjusting member 31. The sliding limiting groove 3171 on the surface of the sliding cylinder 317 limits the adjustment stroke while avoiding structural interference. Combined with the full enclosure protection of the first adjusting member 31 by the protective cover 34, it effectively blocks high-temperature metal splashes and reduces the equipment failure rate.

[0047] In this design, the ingot lifting assembly 33 is fixedly disposed at the front end of the first adjusting member 31; the ingot lifting assembly 33 includes a rotating sleeve 331, which is fixedly disposed at the front end of the first adjusting member 31; a hollow straight tube 332, which is fixedly inserted into the rotating sleeve 331, with its end connected to an external cooling water source and its front end closed; and a connecting support arm 333, one end of which is fixedly sleeved on the hollow straight tube 332, and the other end of which is closed. A support rod 334 is sleeved at one end; a main rotating drum 335 is rotatably mounted on the support rod 334 via a bearing; a lifting knife 336 is fixedly mounted at the front end of a hollow straight tube 332, located below the main rotating drum 335; the surface of the lifting knife 336 is provided with spray holes 337, which are connected to the hollow straight tube 332; the lifting end of the lifting knife 336 is in contact with the crystallization groove 4101 of the crystallization wheel 41 to achieve demolding of the copper ingot.

[0048] To facilitate the guidance of the demolded copper ingots into the next process, a bridge assembly 32 is included, which is composed of multiple unit bridge components 321. Specifically, each unit bridge component 321 includes a bridge groove 3211 with a hollowed-out notch 3212 at its bottom; a guide rotating cylinder 3213 rotatably disposed in the bridge groove 3211 at the hollowed-out notch 3212; and a collection groove 3214 fixedly disposed below the hollowed-out notch 3212, within which a collection box 3215 can be pulled out. Specifically, the guide rotating cylinder 3213 includes a shaft, two bearings sleeved on the shaft, and a cylinder sleeved on the two bearings. The guide rotating cylinder 3213 of the bridge assembly cooperates with the collection box 3215 to simultaneously collect oxide debris during the transport of the copper ingots.

[0049] To enable adjustment of the guide bridge assembly and its coordination with the ingot lifting assembly, a guide bridge adjusting component is provided within the frame 1. This component includes a guide bridge rotating shaft 323, which is rotatably mounted within the frame 1 via a guide bridge bearing seat 325. One end of the guide bridge rotating shaft 323 extends out of the frame 1 and is fixedly connected to the shaft via a fitting 326. A guide bridge adjusting hydraulic cylinder 322 is fixedly mounted inside the frame 1. The movable end of the hydraulic cylinder 322 is hinged to a guide bridge support arm 324, and the other end of the support arm 324 is fixedly sleeved onto the guide bridge rotating shaft 323. This linkage design, where the guide bridge adjusting hydraulic cylinder 322 drives the guide bridge support arm 324, enables dynamic adjustment of the conveying angle to adapt to different production cycle requirements.

[0050] The working process of this device:

[0051] 1. Preparation stage for spindle production:

[0052] Drive the crystallizing wheel 41 to rotate to the preset position, start the cooling water source, and inject water into the ingot lifting block 336 through the hollow straight pipe 332; operate the rotating handle 315 to finely adjust the position of the ingot lifting block 336 to ensure that the spray hole 337 is directly facing the bottom of the copper ingot in the crystallizing wheel groove 4101.

[0053] 2. Demolding execution stage:

[0054] When the crystallizing wheel 41 rotates and moves the crystallized copper ingot to the ingot lifting station, the lifting knife scrapes the copper ingot from the crystallizing wheel groove 4101. At the same time, cooling water is sprayed out from the spray hole 337 through the hollow straight pipe 332 to form a water film lubrication interface, which separates the copper ingot from the crystallizing wheel groove 4101. The scraped copper ingot comes into contact with the surface of the main rotating roller 335, reducing sliding friction. The demolded copper ingot is conveyed along the guide rotating cylinder 3213 of the unit bridge 32, and the oxide debris falls into the collection box 3215 through the hollow notch 3212.

[0055] 3. Dynamic adjustment and maintenance phase:

[0056] During the production process, the stroke of the drive rod 314 is adjusted according to the specifications of the copper ingot to compensate for the wear of the ingot lifting block 336 in real time.

[0057] Regularly remove the collection box 3215 to clean the debris. After the protective cover 34 is removed, the worn ingot-raising component 33 can be directly replaced without stopping the machine and disassembling the whole machine.

[0058] 4. Shutdown protection phase:

[0059] After shutting off the cooling water supply, the reverse rotation of the drive rod 314 causes the lifting block 336 to disengage from the crystallizing wheel groove 4101, preventing cold deformation of the equipment; the operation of the guide bridge adjusting hydraulic cylinder 322 resets the guide bridge assembly to a horizontal position, preventing the mechanism from being subjected to long-term stress.

[0060] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
