Description

Technical Field

[0001] The utility model relates to the technical field of bellows welding, in particular to a multi-angle shaking enameled wire painting die. 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

DETAILED DESCRIPTION

[0022] 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.

[0023] Example: Reference Figure 1 , Figure 2 and Figure 5 As shown, a multi-angle shaking enameled wire painting mold shown, comprising a mold cover 2, a mold base 1 with a material storage cavity, and multiple sets of inlet guide wheels 3 and multiple sets of outlet guide wheels 4 installed on the mold base 1, a mounting plate 5 is installed on the mold base 1, and multiple sets of paint scraping mold sleeves 6 with conical structures inside 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°, and the mounting plate 5 is vertically installed on the inclined wall of the material storage cavity On the top, the paint scraping mold sleeve 6 is arranged parallel to the inclined wall of the storage chamber, and also includes a wire pressing mechanism, which includes a mounting horizontal plate 7 installed on the inner wall of the storage chamber, and the mounting horizontal plate 7 is threadedly connected with a screw 8, 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 horizontal plate 7, and a plurality of 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;

[0024] It also includes a multi-angle material shaking mechanism, which controls the multi-directional swing of the U-shaped rod 10 while it moves upward, so that the paint stained on the U-shaped rod 10 and the crimping wheel 11 is shaken off into the material storage cavity.

[0025] 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);

[0026] The U-shaped rod 10 can be moved downward by rotating the screw 8, so that the copper wire moves into the wheel groove of the wire pressing wheel 11 and brings the copper wire into the paint, ensuring that the copper wire part is completely immersed in the paint;

[0027] A multi-angle material shaking mechanism is provided to shake off the paint on the U-shaped rod 10 and the wire pressing wheel 11 from multiple directions, and the shaking effect is good. If the excess paint is not shaken off in time, the paint on the wire pressing 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).

[0028] 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.

[0029] As a preferred implementation in this embodiment, Figure 2-4 As shown, the multi-angle material shaking 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 reset 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.

[0030] A movable sleeve 17 is slidably disposed on the U-shaped rod 10, and a first swing spring 18 is rotatably disposed on the upper end of the movable sleeve 17;

[0031] The U-shaped rod 10 includes a crossbar and two vertical rods, and the two vertical rods are connected to the crossbar via a second swing spring 19 that is vertically arranged.

[0032] Before each replacement of the copper wire, that is, before installing a 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 is moved 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 can move upward, and cooperate with the reset spring 16 to make the second semicircular protrusion 13 move along the wave path composed of multiple first semicircular protrusions, so that the vertical rod of the U-shaped rod 10 can move back and forth left and right, and cooperate with the first swing spring 18 and the second swing spring 19 to drive the cross bar arranged below to shake at multiple angles, so as to shake off the paint on the U-shaped rod 10 and the wire pressing wheel 11.

[0033] It should be noted that the movable sleeve 17 is a wear-resistant sleeve.

[0034] As a preferred implementation in this embodiment, Figure 4 As shown, the outer wall of the sliding sleeve 15 and the opposite ends of the two limiting plates 14 are provided with balls 20 , and the balls 20 are in contact with the mounting transverse plate 7 .

[0035] The friction between the sliding sleeve 15 and the mounting cross plate 7 is reduced by the balls 20 .

[0036] 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.
