Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire painting, in particular to an enameled wire painting mould. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, then painted and baked several times. However, it is not easy to produce products that meet both standard requirements and customer requirements.

[0003] It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0004] The painting process is particularly important in the production process of enameled wire. The interior of the mold base of the existing painting mold (composed of a guide wheel, a paint scraping mold, a mold cover and a mold base, and the mold cover cannot completely seal the storage cavity in the mold base) is generally configured as a rectangular cavity, and the inner cavity is used to store paint, resulting in the paint being spread flat in the rectangular cavity, increasing the contact area with the air. The oxygen, humidity and other pollutants in the air may react with the chemical components in the paint, causing the paint to deteriorate, dry or agglomerate. This deterioration will directly affect the fluidity and adhesion of the paint, making the painting process difficult and may cause a decrease in the quality of the paint layer, such as unevenness, bubbles or peeling. Therefore, the present application provides an enameled wire painting mold to meet the needs. Utility Model Content

[0005] The purpose of the present application is to provide an enameled wire painting die, which is used to solve the technical problem in the prior art that the paint is spread flat in a rectangular cavity, resulting in large-area deterioration.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an enameled wire painting mold, comprising a mold cover, a mold base with a material storage cavity, and multiple groups of inlet guide wheels and multiple groups of outlet guide wheels installed on the mold base, a mounting plate is installed on the mold base, and multiple groups of paint scraping mold sleeves with conical structures inside are installed on the mounting plate, the material storage cavity is set to a V-shaped structure, and the angle between the inclined wall of the material storage cavity and the Y-axis is 30° to 40°, the mounting plate is vertically installed on the inclined wall of the material storage cavity, the paint scraping mold sleeve is arranged parallel to the inclined wall of the material storage cavity, and also includes a wire pressing mechanism, the wire pressing mechanism includes a mounting cross plate installed on the inner wall of the material storage cavity, and a screw is threadedly connected to the mounting cross plate, a U-shaped rod is arranged below the screw, and both upper ends of the U-shaped rod slide through the mounting cross plate, a plurality of wire pressing wheels are rotatably arranged on the U-shaped rod at equal intervals, the lower end of the screw is rotatably connected to the U-shaped rod, and a hand wheel is installed on the upper end of the screw.

[0007] As a preferred implementation manner in this embodiment, it also includes a shaking feeding mechanism. Before each replacement and installation of the copper wire, the U-shaped rod is controlled to swing left and right while moving upward, so that the paint on the U-shaped rod and the wire pressing wheel is shaken off into the storage cavity.

[0008] As a preferred implementation manner in the present embodiment, the shaking unloading mechanism includes two sliding sleeves with two limit plates arranged above and below and a first semicircular protrusion and a second semicircular protrusion arranged in cooperation, the upper end of the mounting cross plate is symmetrically provided with two movable openings, and the two sliding sleeves are respectively movably arranged in the corresponding movable openings, the two limit plates located on the same sliding sleeve are respectively located on the upper and lower sides of the mounting cross plate, the two sliding sleeves are respectively slidably sleeved on the upper ends of the corresponding U-shaped rods, the upper end of the mounting cross plate is connected to one of the limit plates through a return spring, the U-shaped rod is provided with a section segment, a plurality of groups of the first semicircular protrusions are equidistantly arranged on the section segment, and the second semicircular protrusion is fixedly mounted on the inner wall of the storage cavity;

[0009] A movable sleeve is slidably arranged on the U-shaped rod, and the lower end of the screw rod is rotatably connected to the movable sleeve.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] The utility model has a reasonable structure. The material storage chamber is set as a V-shaped structure, which makes the paint accumulate in a V-shape, thereby reducing the contact area between the paint and the air, thereby avoiding excessive paint deterioration and damage; at the same time, when the angle between the inclined wall of the material storage chamber and the Y-axis is 30° to 40°, this specific angle range enables the paint scraped off by the paint scraping mold sleeve to flow down along the copper wire more smoothly back to the paint accumulation place, avoiding the formation of paint accumulation or blockage near the paint scraping mold sleeve, and also ensuring the continuity of the coating process;

[0012] In the utility model, a shaking feeding mechanism is included. Before each replacement and installation of the copper wire, the U-shaped rod is controlled to move upward and swing left and right at the same time, so that the paint on the U-shaped rod and the wire pressing wheel drips into the storage cavity. If it is not removed in time, the paint on the wire pressing wheel is easily solidified, thereby affecting the coating quality of the enameled wire in the subsequent coating process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1-2 and Figure 5 The enameled wire painting mold shown includes a mold cover 2, a mold base 1 with a material storage cavity, and multiple groups of inlet guide wheels 3 and multiple groups of outlet guide wheels 4 installed on the mold base 1. A mounting plate 5 is installed on the mold base 1, and multiple groups of paint scraping mold sleeves 6 with conical internal structures are installed on the mounting plate 5. The material storage cavity is set to a V-shaped structure, and the angle between the inclined wall of the material storage cavity and the Y-axis is 30° to 40°. The mounting plate 5 is vertically installed on the inclined wall of the material storage cavity, and the paint scraping mold sleeve 6 is arranged parallel to the inclined wall of the material storage cavity. It also includes a wire pressing mechanism, which includes a mounting cross plate 7 installed on the inner wall of the material storage cavity, and a screw 8 is threadedly connected to the mounting cross plate 7, a U-shaped rod 10 is arranged below the screw 8, and both upper ends of the U-shaped rod 10 slide through the mounting cross plate 7, and multiple wire pressing wheels 11 are rotatably arranged on the U-shaped rod 10 at equal intervals, the lower end of the screw 8 is rotatably connected to the U-shaped rod 10, and a hand wheel 9 is installed on the upper end of the screw 8.

[0022] The storage chamber is set to a V-shaped structure, which will cause the paint to accumulate in a V-shape, thereby reducing the contact area between the paint and the air, thereby avoiding excessive paint deterioration and damage; at the same time, when the angle between the inclined wall of the storage chamber and the Y-axis is 30° to 40°, this specific angle range allows the paint scraped off by the paint scraping mold sleeve 6 to flow down along the copper wire more smoothly back to the paint accumulation place, avoiding the formation of paint accumulation or blockage near the paint scraping mold sleeve, and also ensuring the continuity of the coating process (the refluxed paint can be reused);

[0023] The U-shaped rod 10 can be moved downward by rotating the screw rod 8, so that the copper wire moves into the wheel groove of the wire pressing wheel 11 and is driven into the paint to ensure that the copper wire part is completely immersed in the paint.

[0024] It should be noted that, first, if the angle between the inclined wall of the storage chamber and the Y-axis is too large, it is easy to cause the copper wire to deform too seriously, thereby affecting the quality of the finished product. If the angle is too small, it is easy to cause paint accumulation or blockage near the paint scraping mold sleeve 6; second, the wire pressing wheel 11 is located directly above the lowest point inside the storage chamber.

[0025] As a preferred implementation mode in this embodiment, it also includes a shaking feeding mechanism. Before each replacement and installation of the copper wire, the U-shaped rod 10 is controlled to swing left and right while moving upward, so that the paint on the U-shaped rod 10 and the wire pressing wheel 11 is shaken off into the storage cavity.

[0026] The excess paint on the crimping wheel 11 is shaken off by the shaking feeding mechanism. If it is not removed in time, the paint on the crimping wheel 11 will easily solidify, thereby affecting the coating quality of the enameled wire in the subsequent coating process (such as causing uneven paint layer thickness, paint nodules and other problems). The shaking feeding mechanism can clean up the excess paint in time to ensure that the thickness and quality of the paint layer applied each time can remain stable.

[0027] As a preferred implementation in this embodiment, Figure 2 and Figure 3 As shown, the shaking unloading mechanism includes two sliding sleeves 15 with two limit plates 14 arranged in an upper and lower manner and a first semicircular protrusion 12 and a second semicircular protrusion 13 arranged in cooperation. Two movable openings are symmetrically arranged on the upper end of the mounting cross plate 7, and the two sliding sleeves 15 are respectively movably arranged in the corresponding movable openings. The two limit plates 14 located on the same sliding sleeve 15 are respectively located on the upper and lower sides of the mounting cross plate 7. The two sliding sleeves 15 are respectively slidably sleeved on the upper ends of the corresponding U-shaped rods 10. The upper end of the mounting cross plate 7 is connected to one of the limit plates 14 through a return spring 16. A section segment is arranged on the U-shaped rod 10. Multiple groups of first semicircular protrusions 12 are equidistantly arranged on the section segment. The second semicircular protrusion 13 is fixedly installed on the inner wall of the storage cavity.

[0028] A movable sleeve 17 is slidably disposed on the U-shaped rod 10 , and the lower end of the screw rod 8 is rotatably connected to the movable sleeve 17 .

[0029] Before replacing the copper wire each time and installing the new copper wire on the painting mold, the screw rod 8 can be rotated to make the screw rod 8 move upward by an end distance, that is, when the original copper wire moves out of the wheel groove of the wire pressing wheel 11, the screw rod 8 can be continued to be rotated, and the U-shaped rod 10 moves upward. In conjunction with the reset spring, the second semicircular protrusion 13 moves along the wave path formed by multiple first semicircular protrusions, thereby making the U-shaped rod 10 move back and forth quickly, thereby shaking off the paint on the U-shaped rod 10 and the wire pressing wheel 11.

[0030] It should be noted that, firstly, the portion of the U-shaped rod 10 equipped with the first semicircular protrusion 12 can smoothly pass through the inner cavity of the sliding sleeve 15; and secondly, the movable sliding sleeve 17 is a wear-resistant sliding sleeve.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
