Description

Technical Field

[0001] This utility model relates to the field of micro-enameled wire cooling technology, specifically a cooling device for cooling micro-enameled wires. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer needs is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.

[0003] In the existing technology, the filtration and return of coolant to the cooling tank often suffers from insufficient cleanliness due to the single filtration stage and fixed filtration structure. Using a single-stage filter to filter the coolant can only remove some larger impurities and cannot effectively intercept fine impurities. These residual impurities come into contact with the fine enameled wires after being returned to the cooling tank with the coolant, and are easy to adhere to the surface of the paint film, causing contamination or even scratching the paint film, ultimately affecting product quality.

[0004] Therefore, this utility model proposes a cooling device for cooling fine enameled wires to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for cooling fine enameled wires, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for cooling fine enameled wires, comprising a cooling box and a filter box, wherein conduits are fixedly connected to both sides of the surface of the cooling box, and a water pump is fixedly installed on the surface of the conduits; the interior of the filter box is connected to the interior of the cooling box through the conduits and the water pump. A hydraulic cylinder is fixedly installed at the center of the bottom of the filter box. A hydraulic telescopic rod is fixedly installed on the top of the hydraulic cylinder. A lifting plate is fixedly installed on the top of the hydraulic telescopic rod. A filter plate is fixedly installed on the top of the lifting plate.

[0007] Preferably, push rods are fixedly installed on both sides of the top of the filter plate, and positioning plates are fixedly installed on both sides of the upper end of the filter box. Lifting rods are slidably engaged on both sides of the inside of the positioning plates, and a baffle is fixedly installed on one side of the surface of the lifting rods.

[0008] Preferably, a second filter plate is fixedly installed on the upper part of the filter box surface. The diameter of the filter holes of the first filter plate is larger than that of the second filter plate, which can perform secondary filtration treatment on impurities in the coolant.

[0009] Preferably, the conduits are symmetrically distributed on both sides of the cooling box and the filter box, and one side of the conduit surface penetrates the interior of the filter box and is connected to the bottom of the inner side of the lifting plate.

[0010] Preferably, the lifting plate is triangular in shape, hollow inside, and connected to a surface of the filter plate.

[0011] Preferably, the lifting plate and the filter plate move up and down inside the filter box via a hydraulic cylinder and a hydraulic telescopic rod.

[0012] Preferably, the lifting plate and the filter plate are adjusted to move up and down, which drives the push rod to move upward synchronously and contact the bottom of the lifting rod, so that the lifting rod drives the baffle to move up and down inside the filter box.

[0013] Preferably, the baffle is raised and lowered to separate from the surface of the second filter plate, so that the interior of the filter box is connected to the interior of the cooling box through the second filter plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The cooling device for cooling fine enameled wires proposed in this utility model uses a hydraulic cylinder inside the filter box to drive a hydraulic telescopic rod, which in turn moves a lifting plate and a filter plate one up and down. On the one hand, the triangular hollow structure of the lifting plate can efficiently receive the circulating medium, and together with the filter plate one, it can achieve primary filtration, removing larger impurities in the medium and preventing the cooling medium from contaminating the enamel film of the enameled wire. On the other hand, when the lifting plate moves up and down, it drives a push rod to push the lifting rod, causing the baffle to separate from the filter plate two. At the same time, the coolant filtered in the first stage is transferred to the position of the filter plate two by tilting, avoiding some coolant from settling inside the cooling box. The filter plate two is then used for secondary filtration. The dual filtration design improves the cleanliness of the cooling medium, and the lifting and adjusting of the filter structure facilitates subsequent cleaning and maintenance of the filter screen, effectively ensuring the cooling quality of the fine enameled wires.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1 Please see Figure 1 and Figure 3 A cooling device for cooling fine enameled wires includes a cooling box 100 and a filter box 103. The cooling box 100 has conduits 101 fixedly connected to both sides of its surface. A water pump 102 is fixedly installed on the surface of the conduits 101. The filter box 103 is connected to the interior of the cooling box 100 through the conduits 101 and the water pump 102. The conduits 101 are symmetrically distributed on both sides of the cooling box 100 and the filter box 103, and one side of the surface of the conduits 101 penetrates the interior of the filter box 103 and is connected to the bottom of the inner side of the lifting plate 202. A hydraulic cylinder 200 is fixedly installed at the center of the bottom of the filter box 103. A hydraulic telescopic rod 201 is fixedly installed on the top of the hydraulic cylinder 200. A lifting plate 202 is fixedly installed on the top of the hydraulic telescopic rod 201. A filter plate 203 is fixedly installed on the top of the lifting plate 202.

[0019] In use, the water pump 102 on the conduit 101 is started, which drives the cooling medium in the cooling box 100 to flow along the conduit 101 to the filter box 103. One end of the conduit 101 passes through the inside of the filter box 103 and is precisely connected to the bottom of the inner side of the lifting plate 202, so that the cooling medium can flow directly into the lifting plate 202. The hydraulic cylinder 200 at the bottom of the filter box 103 provides power for lifting and adjusting. After starting, the hydraulic telescopic rod 201 pushes the lifting plate 202 and the filter plate 203 fixed at the top to rise and fall in the filter box 103, adjusting the contact position between the filter plate 203 and the cooling medium. When the cooling medium enters the lifting plate 202 from the conduit 101, it will flow through the filter plate 203 to complete the filtration of impurities.

[0020] Example 2 Based on Example 1, please refer to Figure 3Push rods 204 are fixedly installed on both sides of the top of filter plate 203. Positioning plates 205 are fixedly installed on both sides of the upper end of the filter box 103. Lifting rods 206 are slidably engaged on both sides of the inside of the positioning plates 205. A baffle 207 is fixedly installed on one side of the surface of the lifting rods 206. Filter plate 208 is fixedly installed on the upper part of the surface of the filter box 103. The lifting plate 202 is triangular in shape, hollow inside, and communicates with the surface of filter plate 203.

[0021] In use, the hydraulic cylinder 200 at the bottom of the filter box 103 drives the lifting plate 202 to rise and fall through the hydraulic telescopic rod 201, which simultaneously moves the first filter plate 203 and the push rods 204 on both sides of the top. When the lifting plate 202 rises to the preset height, the top of the push rod 204 contacts the bottom of the lifting rod 206 that is slidably engaged in the positioning plate 205 and pushes it, causing the lifting rod 206 to drive the baffle 207 fixed on one side to rise synchronously, so that the baffle 207 separates from the second filter plate 208 fixed on the upper part of the filter box 103, and the medium after primary filtration flows through the second filter plate 208 to complete the secondary filtration.

[0022] Example 3 Based on Example 2, please refer to Figures 3-4 The lifting plate 202 and filter plate 203 move up and down inside the filter box 103 via the hydraulic cylinder 200 and the hydraulic telescopic rod 201. The lifting plate 202 and filter plate 203 are adjusted up and down, which drives the push rod 204 to move upward synchronously and contact the bottom of the lifting rod 206. This causes the lifting rod 206 to drive the baffle 207 to move up and down inside the filter box 103. The baffle 207 separates from the surface of the filter plate 208, so that the inside of the filter box 103 is connected to the inside of the cooling box 100 through the filter plate 208.

[0023] In use, the cooling tank 100 and the filter tank 103 form a closed cooling medium circulation system through the conduit 101 and the water pump 102. After the water pump 102 drives the medium from the cooling tank 100 into the filter tank 103, it first enters the triangular hollow lifting plate 202. The hydraulic cylinder 200 at the bottom of the filter tank 103 is activated, which drives the lifting plate 202 and the top filter plate 203 to rise and fall within the filter tank 103 through the hydraulic telescopic rod 201. When the lifting plate 202 rises, the push rods 204 on both sides of its top move upwards simultaneously, and the lifting rod 204 slides and engages with the positioning plate 205. 06 The bottom contacts and continuously pushes, causing the lifting rod 206 to drive the fixed baffle 207 on one side to rise along the inner wall of the filter box 103 until the baffle 207 is completely separated from the surface of the filter plate 208 on the upper part of the filter box 103. At this time, the interior of the filter box 103 forms a communication channel with the cooling box 100 through the filter plate 208. The cooling medium is first guided to the filter plate 203 through the lifting plate 202 to complete the primary filtration, and then undergoes secondary filtration through the opened filter plate 208. Finally, the clean medium flows back to the cooling box 100 through the conduit 101 to continuously cool the fine enameled wire.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
