Description

Technical Field

[0001] This invention relates to the field of coil insulation technology, and particularly to a coil insulation device. Background Technology

[0002] In the field of hot-rolled wire rod production, the performance of the wire rod depends to a certain extent on the precise control of the post-rolling cooling process. Especially in the critical temperature range of phase transformation, slight differences in cooling rate can directly lead to changes in the austenite transformation path, thereby affecting the mechanical properties of the final product. Existing coiling stations, as key equipment following the coiling machine and air-cooling line, mainly undertake the functions of coil forming and storage. However, their traditional structures lack effective heat preservation and temperature control mechanisms, becoming a bottleneck restricting the quality of special steel production.

[0003] The shortcomings of conventional requisition stations are reflected in two aspects: First, there is no active insulation structure. The coil is directly exposed to the environment during the coiling process. The temperature difference between winter and summer can cause fluctuations in the cooling rate, resulting in uneven austenitic phase transformation and ultimately causing batch-to-batch differences in the mechanical properties of the coil. Secondly, there is a lack of targeted slow cooling solutions. Special steel production requires maintaining a precise cooling rate during the phase transformation stage, but traditional equipment relies solely on natural cooling or residual cold energy from air-cooled lines, which often fails to meet process requirements. In addition, existing insulation devices generally suffer from insufficient material temperature resistance and poor structural adaptability, making it difficult to withstand the high-temperature environment when coils are first formed, and the cost of disassembly and maintenance during frequent repairs is high. Summary of the Invention

[0004] This invention provides a roll-up insulation device.

[0005] A winding and heat preservation device includes: a winding station, a base on the right side of the winding station, an H-shaped column on the left side of the base, two sets of hydraulic cylinders on the top of the base, a roller on the upper part of the H-shaped column, and heat preservation covers symmetrically arranged on the roller. The top of the telescopic rod of the hydraulic cylinder is movably connected to the cam of the heat preservation cover on one side of the roller. The hydraulic cylinder is used to initiate the extension and retraction by driving the cam of the insulation cover along the roller to complete the opening and closing work. The insulation cover is located at the coiling point of the coiling station.

[0006] Preferably, the insulation cover is equipped with insulation material inside and stainless steel plate support on the outside, and the insulation cover is divided into front and back parts.

[0007] Preferably, the upper part of the H-shaped column is fixedly connected to the left side of the cylinder body of the hydraulic cylinder, and the right side of the cylinder body of the hydraulic cylinder is fixedly connected to the top of the base.

[0008] Preferably, the H-shaped columns are used to support the insulation cover, and the insulation material inside the insulation cover is aluminum silicate cotton blanket.

[0009] Compared with the prior art, the present invention provides a winding insulation device, which has the following beneficial effects: The insulation cover is infinitely adjustable through a drive mechanism consisting of a hydraulic cylinder and an H-shaped column, and a cam connected to a roller. This allows for precise control of the enclosure degree of the insulation space according to the process requirements of different steel grades. This dynamic adjustment capability reduces fluctuations in the coil cooling rate, effectively solving the problem of cooling rate fluctuations caused by temperature differences between winter and summer, thus providing long-term insulation while ensuring that the austenitic phase transformation remains within a controllable path.

[0010] The symmetrical support structure of the H-shaped columns ensures the stability of the insulation cover under high-frequency operation and extends its service life compared to the traditional cantilever structure. Attached Figure Description

[0013] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0014] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0015] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0016] Reference Figures 1-5 As shown, a coil collecting and heat preservation device in this embodiment includes a coil collecting station 1. The coil collecting station 1 serves as the core area for coil collection and slow cooling. A base 401 is fixedly installed on its right side. The base 401 is made of welded steel plate, which provides stable support for the entire device and avoids structural displacement during high-frequency operation.

[0017] The left side of the base 401 is welded and fixed to the H-shaped column 402. The welded parts are inspected to ensure there are no false welds. The H-shaped column 402 is made of seamless steel pipe, which has both high strength and lightweight characteristics. It is mainly used to support the weight of the insulation cover 2 and restrict its movement trajectory. Two sets of hydraulic cylinders 3 are symmetrically arranged on the top of the base 401. The right side of the cylinder body of the hydraulic cylinder 3 is fixed to the top of the base 401 by bolts, and the left side of the cylinder body is welded and fixed to the upper part of the H-shaped column 402. The two-way fixing structure can counteract the lateral force generated when the hydraulic cylinder extends and retracts, ensuring stable power output.

[0018] The upper part of the H-shaped column 402 is movably connected to the roller shaft 4 via a deep groove ball bearing. The roller shaft 4 is made of 45 steel and heat-treated with chrome plating for rust prevention. The outer periphery is symmetrically fitted with insulation covers 2. The insulation covers 2 can rotate flexibly around the roller shaft 4 to achieve opening and closing. The top of the telescopic rod of the hydraulic cylinder 3 is movably connected to the cam of the insulation cover 2 on one side of the roller shaft 4 via a pin. The pin is made of stainless steel and can transmit the telescopic power of the hydraulic cylinder, drive the cam to rotate along the roller shaft 4, and thus precisely control the opening and closing angle of the insulation cover 2.

[0019] The insulation cover 2 is filled with aluminum silicate cotton blanket, which has a low thermal conductivity at high temperatures and can effectively prevent heat loss from the coil. The exterior of the insulation cover 2 is welded with 304 stainless steel plate supports to protect the internal cotton blanket from mechanical damage. After the coil collection station 1 completes the coil collection, the hydraulic cylinder 3 starts to extend and retract, which drives the insulation cover 2 to close around the roller shaft 4 through the cam, forming a closed insulation space. When uncoiling, the hydraulic cylinder extends and retracts in the opposite direction, driving the insulation cover to open, realizing flexible switching between insulation and operation.

[0020] In some examples, a temperature sensor is fixedly installed on the inner side of the H-shaped column 402 by a bracket. The detection end of the temperature sensor faces the winding area of ​​the winding station 1. At the same time, an LCD display is installed on the outer side of the base 401. The sensor and the display are electrically connected by wires. The display can display the temperature of the winding area in real time. The operator can adjust the opening and closing degree of the heat preservation cover according to the temperature data.

[0021] The working principle of this invention is: Before using the coil insulation equipment, a suitable installation position should be selected according to the actual layout of the coil station 1. The base 401 should be placed stably on the ground to the right of the coil station 1. Its rectangular structure ensures overall stability and avoids displacement during subsequent high-frequency operations.

[0022] Next, the core components are assembled: First, the left side of the H-shaped column 402 is welded and fixed to the base 401. The welded parts are inspected to eliminate the risk of false welding, ensuring that the column can stably bear the weight of the insulation cover 2. Then, the right side of the cylinder body of the two sets of hydraulic cylinders 3 is fixed to the top of the base 401 with M16 bolts, and the left side of the cylinder body is welded to the upper part of the H-shaped column 402 to form a two-way fixed structure. This design can counteract the lateral force generated when the hydraulic cylinder extends and retracts, providing a stable foundation for power output.

[0023] The roller 4 is then mounted on the upper part of the H-shaped column 402 using a deep groove ball bearing, ensuring that the roller 4 can rotate freely. The two insulation covers 2 are symmetrically fitted onto the outer circumference of the roller 4. Finally, a stainless steel pin is used to connect the top of the telescopic rod of the hydraulic cylinder 3 to a cam on one side of the insulation cover 2, completing the transmission link. During debugging, the opening and closing angle of the insulation cover 2 needs to be manually tested to ensure that the cam and roller 4 are properly engaged and that the extension and retraction stroke of the hydraulic cylinder matches the opening and closing range of the cover.

[0024] After the hot-rolled wire is spun out by the wire spinneret and formed by the head roller conveyor, it enters the coiling station 1 to complete the coiling and collection.

[0025] According to the slow cooling process requirements of the steel to be processed, the operator controls the hydraulic cylinder 3 to start the extension and retraction: when the hydraulic cylinder extension rod extends, it drives the cam of the insulation cover 2 to rotate along the roller shaft 4 through the pin shaft, thereby pulling the insulation cover 2 to close around the roller shaft 4 towards the coiling point of the coiling station 1.

[0026] When the insulation cover 2 is closed, a closed insulation space is formed in the coiling area of ​​the coiling station 1. At this time, the cooling process of the coil changes from natural cooling to controlled slow cooling. By adjusting the opening and closing degree of the cover, the heat loss rate in the insulation space can be controlled, thereby guiding the austenitic structure of the coil to undergo phase transformation along a preset path, ensuring that the yield strength fluctuation range of the final wire is reduced and improving the mechanical performance stability.

[0027] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
