Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and in particular to a spinning head protective cover that integrates water cooling and easily replaceable wear-resistant liners. Background Technology

[0002] The wire coiler is a key piece of equipment in steel wire production, used to coil high-temperature rolled wire (such as rebar and steel wire) into a uniform spiral shape. Its core component is a high-speed rotating hollow spiral tube. After the wire passes through the mill exit, it enters the tube and is thrown out along the spiral trajectory under the action of centrifugal force, forming a tight coil.

[0003] The head guard of the spinning machine is a protective component installed at the front end of the spinning machine. Its main function is to protect the high-speed rotating spinning tube and internal structure from external damage. It is usually made of high-strength heat-resistant alloy steel and can withstand the radiant heat of high-temperature wire and the impact of impurities such as iron oxide scale.

[0004] The shortcomings of the existing technical solutions are as follows: the protective covers of the existing wire spinning machine heads are mostly fixed by welding, but in long-term high-temperature (600-800℃) environments, the protective covers are prone to deformation. At the same time, under high temperatures, the welded structure is prone to thermal cracking in the weld area, and the residual stress of welding will accelerate creep deformation during long-term thermal cycling, resulting in overall distortion or local collapse of the protective cover. Utility Model Content

[0005] This invention provides a protective cover for a spinning head that integrates water cooling and easily replaceable wear-resistant liners, which can solve the problem of protective covers deforming under long-term high-temperature environments in the prior art.

[0006] A protective cover for a spinning head that integrates water cooling and easily replaceable wear-resistant liners includes a fixed slide rail and an outer fixed shell that are fitted together on an air-cooled transport line. The bottom of the outer fixed shell is fixedly provided with a side plate that slides with the fixed slide rail. An inner protective cover is provided inside the outer fixed shell, and a water cooling system is distributed between the inner side of the outer fixed shell and the inner protective cover.

[0007] As a further embodiment of this utility model: the water cooling system includes a connecting water pipe disposed between the outer fixed shell and the inner protective cover, one end of the connecting water pipe being connected to a first conveying water pipe and the other end being connected to a second conveying water pipe, and the other ends of the first and second conveying water pipes being connected to a cold water conveying device.

[0008] As a further embodiment of this utility model: multiple sets of connecting water pipes are provided, and the multiple sets of connecting water pipes are arranged side by side between the outer fixed shell and the inner protective cover.

[0009] As a further embodiment of this utility model: the connecting water pipe is S-shaped and reciprocates between the outer fixed shell and the inner protective cover.

[0010] As a further embodiment of this utility model: the inner protective cover is coated with ceramic fiber or nano heat insulation material.

[0011] As a further embodiment of this utility model: multiple sets of support frames are fixedly arranged between the outer fixed shell and the inner protective cover. The multiple sets of support frames are arranged in parallel and side by side, and are distributed intermittently with the connecting water pipes.

[0012] As a further embodiment of this utility model, thermally conductive adhesive is filled between the supporting frame and the connecting water pipe.

[0013] As a further embodiment of this utility model, the outer fixed shell is threaded with multiple sets of bolts for fixing the support frame.

[0014] As a further embodiment of this utility model: the outer fixing shell is detachably connected to sleeves on both sides for fixing the first water delivery pipe and the second water delivery pipe.

[0015] As a further embodiment of this utility model, the fixed slide rail is fixed to the air-cooled transport line by bolts.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, when the wire-spinning head starts working, the high-temperature steel wire comes into contact with the inner protective cover, and the inner protective cover absorbs heat and heats up. At this time, the cooling water circulation device starts, and cooling water enters the connecting water pipe through the first delivery water pipe. The cooling water flows in the connecting water pipe. If the connecting water pipes are arranged in multiple sets side by side, they can absorb the heat from the outer fixed shell and the inner protective cover in an all-round and uniform manner, so that the temperature of the protective cover is uniformly controlled. After absorbing heat, the temperature of the cooling water rises and flows back to the cooling water circulation device through the second delivery water pipe, where it is cooled and then circulated again. This water-cooling system, through continuous circulation of cooling water, promptly transfers the heat on the inner protective cover to the outside, effectively reducing the impact of heat on the environment and the direct impact of the high-temperature steel wire on the inner protective cover. It also prevents the inner protective cover from being in a high-temperature environment for a long time, prevents deformation caused by uneven internal stress, and extends the service life of the protective cover.

[0018] 2. In actual assembly, the operator only needs to insert the side mounting plate into the corresponding fixed slide rail to easily assemble the outer fixed shell, achieving rapid assembly and disassembly. This facilitates subsequent cleaning of the oil layer formed by grease falling from the steel wire surface. The inner protective cover, as the part directly in contact with the high-temperature steel wire, is coated with a wear-resistant and thermally stable coating. In high-temperature environments, these heat-insulating materials effectively reduce direct heat conduction from the high-temperature steel wire to the inner protective cover, slowing the rate of temperature rise and reducing the burden on the water cooling system. Simultaneously, they ensure that the inner protective cover is not easily worn during long-term friction, extending its service life. Attached Figure Description

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figures 1 to 4 As shown, this utility model embodiment provides a spinneret protective cover integrating water cooling and easily replaceable wear-resistant liners, including a fixed slide rail 2 bolted to an air-cooled transport line 1. An outer fixing shell 3 is fitted inside the fixed slide rail 2, and side mounting plates 301 are fixedly mounted on both sides of the bottom of the outer fixing shell 3, which slide in cooperation with the fixed slide rail 2 on both sides of the air-cooled transport line 1. Figure 2As shown, in the actual assembly process, the operator only needs to send the side mounting plate 301 into the corresponding fixed slide rail 2 to easily assemble the external fixed shell 3. This design not only simplifies the assembly process, but also achieves the effect of quick disassembly and assembly, which is convenient for subsequent cleaning of the oil layer formed by the grease falling off the surface of the steel wire.

[0027] An inner protective cover 4 is provided inside the outer fixing shell 3. As the part that directly contacts the high-temperature steel wire, a water-cooling system is distributed between the inner side of the outer fixing shell 3 and the inner protective cover 4. This water-cooling system cools the outer fixing shell 3 and the inner protective cover 4 in real time, effectively eliminating heat from the inner protective cover 4 and reducing the impact of heat on the environment and the direct impact of the high-temperature steel wire on the inner protective cover 4. In this way, the inner protective cover 4 is prevented from being in a high-temperature environment for a long time, thus preventing deformation caused by uneven internal stress.

[0028] Specifically, the water cooling system includes a connecting water pipe 7 that is configured between the outer fixed shell 3 and the inner protective cover 4. One end of the connecting water pipe 7 is connected to a first water delivery pipe 5, and the other end is connected to a second water delivery pipe 6. The other ends of the first water delivery pipe 5 and the second water delivery pipe 6 are connected to a cold water circulation device. The first water delivery pipe 5 and the second water delivery pipe 6 ensure a continuous flow of cooling water in the connecting water pipe 7. During the flow of this cooling water, the heat on the outer fixed shell 3 and the inner protective cover 4 can be transferred to the outside in a timely manner, thereby effectively avoiding the problem of deformation of the inner wall of the inner protective cover 4 caused by heat accumulation.

[0029] In one specific embodiment, such as Figure 4 As shown, to further enhance the cooling effect, multiple sets of connecting water pipes 7 are provided. These multiple sets of connecting water pipes 7 are arranged side by side between the outer fixed shell 3 and the inner protective cover 4, and each set of connecting water pipes 7 constitutes an independent cooling water flow channel. This allows the outer fixed shell 3 and the inner protective cover 4 to be cooled more evenly, thereby ensuring the temperature control effect of the entire protective cover.

[0030] In another specific embodiment, the connecting water pipe 7 can also be arranged in an S-shape, reciprocating between the outer fixed shell 3 and the inner protective cover 4. This design allows the cooling water to fully absorb the heat from the outer fixed shell 3 and the inner protective cover 4 during its flow, thereby achieving a highly efficient cooling effect.

[0031] In addition to the water cooling system, the inner protective cover 4 is also coated with ceramic fiber or nano-insulating material. These materials have excellent wear resistance and thermal stability, ensuring that the inner protective cover 4 maintains stable performance during long-term use. At the same time, these insulating materials can also effectively reduce the direct heat conduction from the high-temperature steel wire to the inner protective cover 4, thereby further extending the service life of the inner protective cover 4.

[0032] To further enhance the strength and stability of the entire protective cover, multiple sets of support frames 8 are fixedly installed between the outer fixed shell 3 and the inner protective cover 4. These sets of support frames 8 are arranged in parallel and side by side, and are staggered with the connecting water pipes 7. This improves the overall strength and ensures that when the outer fixed shell 3 and the inner protective cover 4 are subjected to metal splashes due to wear or breakage of the wire-spinning tube, they can withstand the splashed metal fragments, thus protecting the safety of the equipment and personnel. In addition, thermally conductive adhesive is filled between the support frames 8 and the connecting water pipes 7. This material has good thermal conductivity and can ensure the heat conduction effect between the connecting water pipes 7 and the inner protective cover 4, thereby ensuring the normal operation of the water cooling system.

[0033] Bolts for fixing the inner protective cover 4 are threaded onto the outer fixed shell 3 and the support frame 8, which are used to make the inner protective cover 4 close to the support frame 8, and also facilitate the replacement and maintenance of the inner protective cover 4 after the coating on the surface of the inner protective cover 4 is scratched.

[0034] Finally, to facilitate the management and maintenance of the first water delivery pipe 5 and the second water delivery pipe 6, sleeves 9 for fixing these two pipes can be detachably connected to both sides of the outer fixing shell 3. These sleeves 9 can maintain the relative position of the first water delivery pipe 5 and the second water delivery pipe 6, preventing them from shaking or falling off during use, thereby ensuring the stability of the entire water cooling system.

[0035] Working principle: The operator first bolts the fixed slide rail 2 onto the air-cooled transport line 1, and then sends the side mounting plate 301 at the bottom of the outer fixed shell 3 into the corresponding fixed slide rail 2 on both sides of the air-cooled transport line 1. Due to the sliding fit between the side mounting plate 301 and the fixed slide rail 2, the outer fixed shell 3 can be smoothly positioned, completing the initial assembly.

[0036] When the wire-spinning head starts working, the high-temperature steel wire enters the production area and comes into direct contact with the inner protective cover 4. The inner protective cover 4 absorbs the heat emitted by the high-temperature steel wire, causing its temperature to rise rapidly. At the same time, the cooling water circulation device is activated, and cooling water enters the connecting water pipe 7 through the first delivery water pipe 5. The cooling water flows in each independent cooling water flow channel, which can absorb the heat from the outer fixed shell 3 and the inner protective cover 4 in an all-round and uniform manner, so that the temperature of the entire protective cover is uniformly controlled.

[0037] After absorbing heat, the cooling water's temperature rises, and it then flows back to the cold water circulation device through the second water delivery pipe 6. In the cold water circulation device, the hot water is cooled and becomes cold water again, which is then delivered to the first water delivery pipe 5, forming a continuous cooling water circulation. This effectively transfers the heat from the inner protective cover 4 to the outside environment, reducing the impact of heat on the environment and the direct impact of the high-temperature steel wire on the inner protective cover 4. It also prevents the inner protective cover 4 from being in a high-temperature environment for a long time and prevents deformation caused by uneven internal stress.

[0038] The ceramic fiber or nano-insulating material sprayed on the inner side of the inner protective cover 4 can maintain stable performance in high-temperature environments. This effectively reduces the direct heat conduction from the high-temperature steel wire to the inner protective cover 4, slows down the temperature rise rate of the inner protective cover 4, and reduces the burden on the water cooling system; at the same time, it ensures that the inner protective cover 4 is not easily worn during long-term contact and friction with the high-temperature steel wire, thus extending the service life of the inner protective cover 4.

[0039] Multiple sets of support frames 8 are pre-installed between the outer fixed shell 3 and the inner protective cover 4. When the wire tube is worn or broken, causing metal to splash, the support frame 8 can give full play to its strength advantage, resist the splashed metal debris, and protect the safety of equipment and personnel.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
