Description

Technical Field

[0001] This utility model relates to the field of enameled wire production, and in particular to a cutting device for enameled wire. Background Technology

[0002] Enameled wire is a type of wire with one or more layers of insulating varnish coated on the surface of a metal conductor. It is widely used in electrical equipment such as motors, transformers, electromagnetic coils, and electronic components. During the production process of enameled wire, it needs to be cut to a certain length to facilitate subsequent processing.

[0003] There are still some problems in the use of existing enameled wire cutting devices. After long-term use, the cutting blades of the current cutting devices are prone to wear and tear, and replacement is cumbersome. In addition, during the cutting process, because the insulating varnish layer is usually thin and brittle, it is easy to generate debris and dust, which are not easy to clean. Therefore, those skilled in the art have provided an enameled wire cutting device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a cutting device for enameled wire. By placing the blade holder inside the slide and then limiting it through the limiting structure, it is easy to quickly fix the blade holder and facilitate subsequent disassembly, thereby improving the efficiency of blade replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for enameled wire, comprising a base and a control box, wherein the control box is located on one side of the base at the front, and feeding structures are provided at both the front and rear ends of the base.

A slide is provided at the lower center of one side wall of the lifting block, and a knife holder is provided inside the slide. A limiting structure is provided on the upper inner wall of the slide on one side of the knife holder.

[0006] The limiting structure includes a mounting frame. A first electric telescopic rod is fixedly connected to the center of the upper end face of the mounting frame. The output end of the first electric telescopic rod passes through the upper end face of the mounting frame and extends into the interior of the mounting frame.

The control of the first ventilation fan 3056 is activated. The first ventilation fan 3056 blows out the heat transferred from the hot end of the semiconductor cooling chip 3052 to the second heat-conducting fin 3054, which facilitates the long-term use of the semiconductor cooling chip 3052.

[0037] Slide grooves 7 are provided on the upper part of both sides of the base 1 and the lower part of both sides of the bracket 4 to facilitate the guidance of the lifting block 6.

[0038] like Figure 3 As shown, a storage groove 11 is provided at the center of the upper end face of the knife holder 15. A high-frequency vibration generator 12 is fixedly connected inside the storage groove 11. A rubber pad 13 is provided on the inner side wall of the slide rail 8. A cutter 14 is provided on the lower end face of the knife holder 15. The high-frequency vibration generated by the high-frequency vibration generator 12 acts on the knife holder 15, and the knife holder 15 drives the cutter 14 to vibrate at a high frequency. The vibration generated at the contact point between the knife holder 15 and the lifting block 6 is absorbed by the rubber pad 13 and will not affect other parts of the equipment, thus cutting the enameled wire.

[0039] Working principle: During installation, the tool holder 15 is placed inside the slide rail 8. The first electric telescopic rod 902 is extended, which pushes the connecting block 903 downward. The connecting block 903 is moved to one side of the tool holder 15 and then stopped. The second electric telescopic rod 905 is then extended, which pushes the extrusion plate 906 toward the tool holder 15 to clamp the tool holder 15 and improve the stability after installation.

[0040] In use, the enameled wire is conveyed to the rear end through the feeding structure 10 at the front. When cutting is required, the hydraulic cylinder 5 is extended and the high-frequency vibration generator 12 is started. The high-frequency vibration generated by the high-frequency vibration generator 12 acts on the cutter holder 15. The cutter holder 15 drives the cutter 14 to vibrate at high frequency. The vibration generated at the contact point between the cutter holder 15 and the lifting block 6 is absorbed by the rubber pad 13 and will not affect other parts of the equipment, thus cutting the enameled wire.

[0041] The second ventilation fan 306 and the third ventilation fan 309 are activated. The second ventilation fan 306 blows outside air into the first U-shaped tube 301, thereby blowing debris and powder into the first U-shaped tube 301. After being blocked by the filter screen 307, the debris and powder are stored inside the filter screen 307. Then, the semiconductor cooling chip 3052 is activated. The cold end of the semiconductor cooling chip 3052 cools the first heat-conducting fin 3053. When the air passes through the first heat-conducting fin 3053, the cold air inside the first heat-conducting fin 3053 is blown towards the cutter 14, cooling the cutter 14. The first ventilation fan 3056 is activated. The first ventilation fan 3056 blows out the heat transferred from the hot end of the semiconductor cooling chip 3052 to the second heat-conducting fin 3054, which facilitates the long-term use of the semiconductor cooling chip 3052.

[0042] After the cutting is completed, the hydraulic cylinder 5 is controlled to retract, which drives the lifting block 6 upward to complete the cutting. After use, the frame 302 is pulled out by rotating the two limit blocks 303 to facilitate the collection and processing of debris inside the frame 302. The frame 302 is then inserted into the first U-shaped tube 301, and the two limit blocks 303 are rotated to limit the movement. The second ventilation fan 306 is a dustproof fan and will not be affected by dust. The gap between the frame 302 and the first U-shaped tube 301 is sealed by a sealing gasket to prevent air leakage.

[0043] During disassembly, by controlling the retraction of the second electric telescopic rod 905, the second electric telescopic rod 905 drives the extrusion plate 906 to move to one side. Then, by controlling the retraction of the first electric telescopic rod 902, the first electric telescopic rod 902 drives the connecting block 903 to move upward and enter the mounting frame 901 for storage, making it easy to pull out the tool holder 15. The new tool holder 15 is placed inside the slide rail 8. By controlling the extension of the first electric telescopic rod 902, the first electric telescopic rod 902 pushes the connecting block 903 to move downward and stops it on one side of the tool holder 15. Then, by controlling the extension of the second electric telescopic rod 905, the second electric telescopic rod 905 pushes the extrusion plate 906 to move towards the tool holder 15 and clamp the tool holder 15.

[0044] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
