Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire cutting, in particular to a cutting device for enameled wire production. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating 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. 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. In the production of enameled wires, a cutting device is required to cut the enameled wires.

[0003] The existing patent (publication number: CN209583241U) discloses a cutting device for enameled wire production, including a shell, a winding chamber is provided in the shell, a fixed roller is fixedly installed in the winding chamber, a mounting groove is provided on the lower side wall of the winding chamber, and a winding device is fixedly installed in the mounting groove. The winding shaft is driven by a motor to rotate to reel in the enameled wire. When the enameled wire reaches a certain weight, the pin at the top of the winding shaft will be disengaged from the slot of the slider, and the slider will move to the right side under the elastic force of the first spring to cut the enameled wire. The elastic force generated instantly by the first spring can make the cutting knife have a faster moving speed, so it has a better cutting effect on the enameled wire. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: the above-mentioned device accelerates the moving speed of the cutting knife through the rebound force of the first spring, thereby increasing the cutting effect on the enameled wire. However, when the above-mentioned device cuts the enameled wire, it is difficult to clamp the enameled wire, which causes the enameled wire to be easily bent when the cutting knife cuts the enameled wire, thereby causing the cross-section of the cut enameled wire to be easily tilted. Utility Model Content

[0004] In order to improve the above-mentioned problem of accelerating the moving speed of the cutting knife by the rebound force of the first spring and increasing the cutting effect on the enameled wire, it is difficult for the above-mentioned device to clamp the enameled wire when cutting the enameled wire, which causes the enameled wire to be easily bent when the cutting knife cuts the enameled wire, thereby causing the cross-section of the cut enameled wire to be easily tilted. The utility model provides a cutting device for enameled wire production.

[0005] The utility model provides a cutting device for enameled wire production, which adopts the following technical solution:

[0006] A cutting device for enameled wire production, comprising a support seat, a C-shaped plate fixedly connected to the top of the support seat, a cylinder fixedly connected to the top of the transverse plate of the C-shaped plate, a bottom end of a telescopic rod of the cylinder extending to the bottom of the transverse plate of the C-shaped plate and fixedly connected to a cutting knife, and a side of the telescopic rod of the cylinder fixedly connected to a limiting block;

[0007] A C-shaped groove is provided in the middle of the top of the support seat, and L-shaped racks are slidably connected inside the two vertical grooves of the C-shaped groove, and a support plate is fixedly connected to the opposite sides of the two vertical bars of the two L-shaped racks, and a C-shaped rack is fixedly connected inside the side of the telescopic rod of the cylinder;

[0041] Working principle: When the cutting device for enameled wire production is used, the cutting knife 4 is driven downward by the telescopic rod of the cylinder 3, and at the same time, the telescopic rod of the cylinder 3 drives the C-shaped rack 9 downward, drives the gear 10 to rotate and drives the two L-shaped racks 7 and the support plate 8 to move upward to support the enameled wire. When the telescopic rod of the cylinder 3 moves downward, it drives the support bar 501 and the two I-shaped bars 503 to move downward. After the I-shaped bar 503 moves downward and contacts the enameled wire, since the bottom of the lower horizontal bar of the I-shaped bar 503 is lower than the length of the bottom of the cutting knife 4, the telescopic rod of the cylinder 3 continues to drive the cutting knife 4 downward to cut the enameled wire. At the same time, the lower horizontal bar of the I-shaped bar 503 clamps the enameled wire, thereby preventing the cross section of the enameled wire from tilting when it is cut.

[0042] Move the two L-shaped blocks 1103 to the front and rear sides respectively, stretch the tension spring 1104, pass the enameled wire to be cut through the inside of the through groove 1102 and wind it around the side of the winding roller 12, then relax the two L-shaped blocks 1103, so that the two L-shaped blocks 1103 drive the two extrusion blocks 1106 to close inward at the same time through the rebound force of the two tension springs 1104, so that the side of the extrusion block 1106 clamps the enameled wire to ensure that the enameled wire can be in a straight state during the cutting process.

[0043] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model.
