Description

Technical Field

[0001] This utility model relates to the field of electromagnetic wire production dimension inspection technology, specifically an electromagnetic wire production dimension inspection device. Background Technology

[0002] As a key material in power equipment and electronic components, the accuracy and consistency of the outer diameter of electromagnetic wire directly affect the electrical performance and mechanical reliability of the product. In modern continuous production of electromagnetic wire, online outer diameter measuring instruments are core equipment used to monitor and control the outer diameter quality of the product in real time. They are usually installed in the production line and perform dynamic dimensional measurements on the high-speed traveling electromagnetic wire through non-contact measurement methods.

[0003] To ensure measurement accuracy, online outer diameter measuring instruments are usually equipped with wire guide devices at the front and rear. Their function is to position and guide the electromagnetic wire, thereby ensuring that the measuring beam or field of view can be stably aligned with the wire being measured.

[0004] However, during high-speed continuous production, significant heat is generated due to continuous friction between the electromagnetic wire and the guide wheel surface. If this heat cannot be dissipated in time, it will lead to two problems: First, the accumulated heat will cause the temperature of the guide wheel body to rise, which may cause thermal expansion and dimensional changes, indirectly affecting the guiding accuracy and even the accuracy of outer diameter measurement; second, localized high temperatures may cause thermal damage to the varnish insulation layer on the surface of the electromagnetic wire, affecting the insulation performance of the product. Existing guide wheel structures are mostly solid metal rollers with limited heat dissipation paths, mainly relying on natural convection and heat conduction, resulting in low heat dissipation efficiency, which is difficult to meet the requirements of long-term stable operation under high-speed and high-volume conditions.

[0005] Therefore, we propose a device for detecting the dimensions of electromagnetic wire production. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a device for detecting the dimensions of electromagnetic wire production. By incorporating heat dissipation fins and an active fan in the hollow guide roller, combined with a wear-resistant and drag-reducing coating on the surface, it achieves efficient heat dissipation, friction reduction, and wear resistance, thereby improving detection accuracy, wire quality, and device lifespan. This effectively solves the problems in the background technology.

[0007] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electromagnetic wire production size detection device, including an online outer diameter detector, on which wire guide structures are symmetrically fixedly installed on both outer surfaces. The wire guide structure includes a wire guide roller, a limiting plate, a first connecting ring, a cooling fan, a first L-shaped connecting arm, a second L-shaped connecting arm and a second connecting ring, and the wire guide roller is a hollow structure with heat dissipation fins evenly spaced along the axial direction inside.

[0008] Preferably, the number of limiting discs in one set of the guide wire structure is two sets, and the two sets of limiting discs are fixed to the outer walls at both ends of the guide wire roller.

[0009] Preferably, bearings are provided between the first connecting ring, the second connecting ring and the guide roller. The outer walls of one end of the first connecting ring and the second connecting ring are rotatably connected to both ends of the inner cavity of the guide roller through the bearings, and the other ends of the first connecting ring and the second connecting ring protrude to the outside of both ends of the inner cavity of the guide roller.

[0010] Preferably, the first L-shaped connecting arm is fixed between the end of the lower outer surface of the first connecting ring away from the guide roller and the outer wall of the online outer diameter measuring instrument; the second L-shaped connecting arm is fixed between the end of the lower outer surface of the second connecting ring away from the guide roller and the outer wall of the online outer diameter measuring instrument.

[0011] Preferably, the cooling fan is fixed inside the first connecting ring.

[0012] Preferably, the guide roller is made of aluminum alloy, and both the guide roller and the outer wall of the limiting plate are provided with a wear-resistant and drag-reducing coating. The wear-resistant and drag-reducing coating is a composite coating that has undergone hard anodizing treatment and is filled with polytetrafluoroethylene. The total thickness of the wear-resistant and drag-reducing coating is 40μm to 120μm.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a device for detecting the dimensions of electromagnetic wire production, which has the following advantages: 1. This electromagnetic wire production dimension detection device significantly increases the heat dissipation area and enhances heat conduction efficiency by setting axially distributed heat dissipation fins inside the hollow guide roller; combined with the heat dissipation fan installed in the first connecting ring, it actively drives air to flow inside the guide roller to achieve forced convection heat dissipation, which can quickly remove the heat generated by friction and reduce the working temperature of the guide roller; thus improving the stability of the measurement area of ​​the online outer diameter detector and the accuracy of the measurement data.

[0014] 2. The electromagnetic wire production dimension detection device has a composite coating on the surface of the guide roller and the limiting plate, which is hard anodized and filled with polytetrafluoroethylene (PTFE). This coating structure has high hardness, excellent wear resistance and extremely low coefficient of friction. On the one hand, it reduces the frictional resistance during the electromagnetic wire's movement, which is conducive to high-speed production and reduces the risk of surface scratches. On the other hand, it improves the durability of the guide device itself, reduces the maintenance frequency and extends its service life. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides an electromagnetic wire production size detection device, including an online outer diameter detector 1 and a guide wire structure 2 symmetrically fixedly installed on its two outer surfaces.

[0023] The wire guide structure 2 includes a wire guide roller 3, a limiting disc 4, a first connecting ring 5, a cooling fan 6, a first L-shaped connecting arm 7, a second L-shaped connecting arm 8, a second connecting ring 9, and cooling fins 11 disposed inside the wire guide roller 3. A set of wire guide structures 2 contains two sets of limiting discs 4, which are respectively fixed to the outer walls at both ends of the wire guide roller 3 to axially limit the traveling electromagnetic wire and prevent it from deviating.

[0024] The guide roller 3 is made of aluminum alloy and has a hollow structure. Several heat dissipation fins 11 are fixed at equal intervals along the axial direction inside to greatly increase its effective heat dissipation area. The first connecting ring 5 and the second connecting ring 9 are rotatably connected to both ends of the inner cavity of the guide roller 3 via bearings, allowing the guide roller 3 to rotate freely around the connecting rings. One end of the first connecting ring 5 and the second connecting ring 9 is placed inside the guide roller 3 via bearings, while the other end protrudes outside both ends of the guide roller 3.

[0025] One end of the first L-shaped connecting arm 7 is fixedly connected to the protruding end of the lower outer surface of the first connecting ring 5 away from the guide roller 3, and the other end is fixedly installed on the side wall of the online outer diameter measuring instrument 1; similarly, one end of the second L-shaped connecting arm 8 is fixedly connected to the protruding end of the lower outer surface of the second connecting ring 9 away from the guide roller 3, and the other end is also fixedly installed on the side wall of the online outer diameter measuring instrument 1. Through these two sets of L-shaped connecting arms, the entire guide wire structure 2 is stably supported and fixed on both sides of the online outer diameter measuring instrument 1.

[0026] The cooling fan 6 is fixedly installed inside the first connecting ring 5. When the device is running, the cooling fan 6 starts, draws in external cooling air, and drives the airflow to flow sequentially through the first connecting ring 5, the cavity inside the guide roller 3 filled with heat dissipation fins 11, and finally out through the second connecting ring 9, forming a forced convection cooling air duct, thereby efficiently removing the heat generated by the friction between the guide roller 3 and the electromagnetic wire.

[0027] A wear-resistant and resistance-reducing coating 10 is provided on the outer surfaces of both the guide roller 3 and the limiting disk 4. This coating is a composite coating formed by hard anodizing and filling the micropores with polytetrafluoroethylene (PTFE), with a total thickness controlled between 40μm and 120μm. This coating structure has both the high hardness and high wear resistance of the alumina ceramic layer and the low coefficient of friction of PTFE, thereby effectively reducing the frictional resistance and surface wear during the travel of the electromagnetic wire, while maintaining good heat dissipation performance.

[0028] Working Principle: After being led out of the production line, the electromagnetic wire passes sequentially through the surface of the guide roller 3 between the two limiting discs 4 of the guide structure 2 on one side, the measurement area of ​​the online outer diameter measuring instrument 1, and the surface of the guide roller 3 on the other side of the guide structure 2. During this process, the guide roller 3 guides, positions, and supports the electromagnetic wire, ensuring its stable passage through the measurement area and guaranteeing the measurement accuracy of the online outer diameter measuring instrument 1. During operation, the electromagnetic wire generates heat through friction with the surface of the guide roller 3. This heat is rapidly conducted to the internal heat dissipation fins 11 via the highly thermally conductive aluminum alloy guide roller 3. Simultaneously, the forced airflow generated by the cooling fan 6 continuously carries away the heat, effectively suppressing temperature rise. The wear-resistant and drag-reducing coating 10 on the surface reduces the generation of frictional heat and protects the coating film on the wire surface from damage.
