Abstract
Description
Technical Field
[0001] This utility model relates to the field of enameled wire processing technology, specifically to a device for removing enamel coating from enameled wires used in new energy vehicles. Background Technology
[0002] Enamelled wire consists of a conductor and an insulation layer. It is made from bare wire that has been annealed and softened, followed by multiple coatings and baking processes. Currently, enamelled wire stripping devices are generally used for stripping. However, current enamelled wire stripping devices have several shortcomings due to their flawed design: unstable operation, poor processing quality, and impact on the lifespan of cutting tools; the wire not detaching from the tool after cutting, leading to wire jamming and copper chip accumulation, and instability such as wire pulling during high-speed cutting; and short tool life. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a paint removal device for enameled wires of new energy vehicles.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a paint removal device for enameled wires of new energy vehicles: including a mechanism top plate, an intermediate template, and a mechanism bottom plate arranged sequentially from top to bottom;
[0005] A motor plate is fixedly connected above the top plate of the mechanism. Bearing seats are symmetrically fixedly connected to both sides of the top of the motor plate along the middle. The top plate and the motor plate are provided with mutually cooperating through holes in the middle. The top plate and the bottom plate of the mechanism are fixedly connected by four guide pillars. The intermediate template is slidably connected to the four guide pillars. A connecting seat is fixedly connected to the middle of the top of the intermediate template. A crank connecting rod is hinged to the connecting seat. A crankshaft is rotatably connected to the upper end of the crank connecting rod. The shaft of the crankshaft is rotatably connected to the bearing seats.
[0006] A left punch and a right punch are fixedly connected to the lower center of the intermediate template. The left punch and the right punch are symmetrical in structure and arrangement. The cutting heads of the left punch and the right punch are stepped punching cutters, and the stepped punching cutters are in the form of oblique blades.
[0007] Furthermore, the base plate of the mechanism is provided with a tool groove that cooperates with the left punch and the right punch.
[0008] Furthermore, the base plate of the mechanism is provided with mutually cooperating wire guide posts on both sides of the knife groove, and the wire guide posts are provided with wire holes for the enameled wire to pass through.
[0009] Furthermore, the top plate of the mechanism is slidably connected to a cam lower connecting plate, and a cam push rod is fixedly connected to the upper middle part of the cam lower connecting plate. A bearing is rotatably connected to the upper end of the cam push rod. A cam structure is provided in the middle of the crankshaft. Slide rods are symmetrically fixedly connected to each other along the middle of the lower side of the cam lower connecting plate. The slide rods are slidably connected to the middle template. A discharge plate is fixedly connected between the two slide rods. The discharge plate is provided with limiting holes that match the left punch and the right punch.
[0010] The advantages of this invention compared to existing technologies are as follows: This invention uses a cam to press down the enameled wire before punching, which ensures the stability and consistency of the enamel removal process, resulting in higher efficiency and better stability, and significantly extending the service life of the punching tools. The mechanical structure of the connecting rod cam ensures that during operation, when the crankshaft rotates, it first drives the unloading plate downwards, pressing down on the enameled wire. At this time, the connecting rod drives the left and right punches to perform downward punching. The use of wire-passing holes on both sides avoids the problem of wire jamming and copper chip jamming caused by the enameled wire not disengaging from the blade after punching. After punching is completed, the connecting rod rises to the stroke position where the cutter is completely disengaged from the enameled wire, and then the cam structure returns to its original position, and the unloading plate follows... To avoid instability caused by high-speed punching, such as wire pulling, the cutting blade has been optimized with a stepped design. This divides the paint removal process into two parts, preventing copper chips from clogging the waste pipe and significantly reducing the load on the mechanism and motor during the punching process. This also greatly reduces the impact of material stress expansion on the cutting blade and die, thus improving tool life. The cutting blade uses a beveled edge, transforming a straight blade into a beveled blade, which reduces the frontal impact on the tool and minimizes the risk of blade breakage.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] Example 1, in conjunction with Appendix Figure 1-6 A paint removal device for enameled wires in new energy vehicles includes a top plate 1, an intermediate template 2, and a bottom plate 3 arranged sequentially from top to bottom.
[0021] A motor plate 4 is fixedly connected above the top plate 1 of the mechanism. Bearing seats 5 are symmetrically fixedly connected to both sides of the top of the motor plate 4 along the middle. The top plate 1 and the motor plate 4 are provided with mutually cooperating through holes in the middle. The top plate 1 and the bottom plate 3 of the mechanism are fixedly connected by four guide pillars 6. The intermediate template 2 is slidably connected to the four guide pillars 6. A connecting seat 7 is fixedly connected to the middle of the top of the intermediate template 2. A crank connecting rod 8 is hinged to the connecting seat 7. A crankshaft 9 is rotatably connected to the upper end of the crank connecting rod 8. The rotating shaft of the crankshaft 9 is rotatably connected to the bearing seats 5.
[0022] The middle template 2 is fixedly connected to a left punch 10 and a right punch 11 at the bottom center. The left punch 10 and the right punch 11 are symmetrical in structure and arrangement. The cutting heads of the left punch 10 and the right punch 11 are stepped punching cutters, and the stepped punching cutters are in the form of oblique blades.
[0023] In this specific embodiment, the base plate 3 of the mechanism is provided with a knife groove 12 that cooperates with the left punch 10 and the right punch 11.
[0024] In this specific embodiment, the base plate 3 of the mechanism is provided with mutually cooperating wire guide posts 13 on both sides of the knife groove 12, and the wire guide posts 13 are provided with wire holes 14 for enameled wires to pass through.
[0025] In this specific embodiment, the top plate 1 of the mechanism is slidably connected to a cam lower connecting plate 15, and a cam push rod 16 is fixedly connected to the upper middle part of the cam lower connecting plate 15. A bearing 17 is rotatably connected to the upper end of the cam push rod 16. A cam structure 18 is provided in the middle of the crankshaft 9. Slide rods 19 are symmetrically fixedly connected to each other along the middle part of the lower side of the cam lower connecting plate 15. The slide rods 19 are slidably connected to the intermediate template 2. A discharge plate 20 is fixedly connected between the two slide rods 19. The discharge plate 20 is provided with limiting holes that match the left punch 10 and the right punch 11.
[0026] In practice, a motor is installed on the motor plate 4, and the motor shaft is connected to the crankshaft 9. The enameled wire is passed through the two wire holes 14 in sequence. The motor is started, and the motor drives the crankshaft 9 to rotate. The cam structure 18 first presses down the bearing 17. At this time, the bearing 17 rotates, reducing the resistance during the movement. The bearing 17 drives the cam push rod 16 to press down, and the unloading plate 20 presses down first to hold the enameled wire. The crank connecting rod 8 drives the intermediate mold plate 2 to press down, which in turn drives the left punch 10 and the right punch 11 to press down and punch the enameled wire. The method of pressing down the enameled wire first and then punching it is adopted. This method ensures the stability and consistency of the enameling removal process, offering higher efficiency and better stability. It also significantly extends the service life of the left and right punches 10 and 11. The use of wire-passing holes on both sides avoids the problem of wire jamming and copper chip buildup caused by the enameled wire not disengaging from the blades after punching. After punching, the crank connecting rod 8 rises to the position where the left and right punches 10 and 11 are completely disengaged from the enameled wire, after which the cam structure 18 returns to its original position. The unloading plate 20 also rises during this process, avoiding instability factors such as wire pulling caused by high-speed punching. This continuous feeding of the enameled wire enables continuous enameling removal.
[0027] In this design, a stepped punching blade is used to divide the entire paint removal section into two parts. This design can prevent copper chips from jamming the waste pipe and divide the original 23mm punching amount into two parts, which greatly reduces the load on the mechanism and motor during the punching process. It can also significantly reduce the extrusion and impact of material stress expansion on the left punch 10, right punch 11 and the die during punching, thereby improving the tool life. The left punch 10 and right punch 11 adopt oblique cutting edge punching, optimizing the straight tool into an oblique cutting edge punch, thus changing punching into shearing, which can reduce the frontal impact force on the tool during punching and reduce the problem of tool breakage.
