The stripping knife has a first stripping hole for initially stripping the enamel film of the wire, and the stripping mold has a second stripping hole with a diameter smaller than the first stripping hole for further fine stripping of the enamel film of the wire after the initial stripping.
[0006] As a further improvement and optimization of this solution, a sizing die is also provided between the peeling knife and the peeling die.

Figure 1 DD section view, Figure 6 This utility model relates to a wire stripping device. Figure 1 CC section view, Figure 7 This is a side view of a wire stripping device according to the present invention. Figure 1-7 As shown, a preferred embodiment of a wire stripping device for enameled wire 5 is illustrated, comprising: a frame 1, wherein a rotatable guide wheel 2, a stripping knife 3, and a stripping mold 6 are arranged sequentially along the transverse direction on the frame 1; the stripping knife 3 has a first stripping hole 31 for initially stripping the enamel film of the enameled wire 5; and the stripping mold 6 has a second stripping hole 61 with a diameter smaller than the first stripping hole 31 for further fine stripping of the enamel film of the enameled wire 5 after the initial stripping of the enamel film.
[0036] In this embodiment, the first segment 411 of the enameled wire 5 is connected to the wire drawing machine by passing through the guide wheel 2, the first stripping hole 31, and the second stripping hole 61 in sequence. Under the traction force of the wire drawing machine, the enameled wire 5 passes through the guide wheel 2, the first stripping hole 31, and the second stripping hole 61 in sequence. When the enameled wire 5 passes through the first stripping hole 31, the first stripping hole 31 uses the aperture to initially peel off the enamel coating on the enameled wire 5. Then, the second stripping hole 61 uses the aperture to perform fine peeling on the enameled wire 5, thereby achieving efficient and complete removal of the enamel coating from the surface of the enameled wire 5. The peeling is precise, does not take away the copper material, and has high peeling efficiency.
[0037] Furthermore, as a preferred embodiment, in order to adapt the stripping mold 6 to enameled wires 5 of different specifications that have undergone initial enamel film stripping by the stripping knife 3, the stripping device also includes a sizing die 4 disposed between the stripping knife 3 and the stripping mold 6.

[0038] Furthermore, as a preferred embodiment, the sizing die has a sizing hole 41. When the enameled wire 5 passes through the sizing hole 41, the enameled wire 5 is axially pulled to a predetermined diameter. The enameled wire 5, after passing through the first stripping hole, passes through the sizing hole 41 and the second stripping hole in sequence under the traction of the wire drawing machine. When passing through the sizing hole 41, the diameter of the hole is used to axially pull the enameled wire 5 to meet the size requirements for the enameled wire 5 to enter the second stripping hole.
[0039] Furthermore, as a preferred embodiment, in order to further improve the initial enamel film peeling effect of the first peeling hole on the enameled wire 5, the discharge end of the first peeling hole 31 has a plurality of circumferentially distributed peeling claws 32, each peeling claw 32 being inclined toward the center line of the first peeling hole 31. By the inclined setting of the peeling claws 32 and the use of the tail end of the peeling claws 32 to initially peel off the enamel film of the enameled wire 5, the initial peeling effect is improved.
[0040] Furthermore, as a preferred embodiment, the second stripping hole 61 includes a feeding section 611, a stripping section 612, and a discharging section 613 that are coaxially connected in sequence. In order to facilitate the smooth insertion of the sized enameled wire 5 into the second stripping hole 61, both the feeding section 611 and the discharging section 613 are flared. In order to improve the fine stripping effect on the enamel film of the enameled wire 5, the cross-section of the stripping section 612 is set with a sharp angle.
[0041] Furthermore, as a preferred embodiment, the sizing hole 41 includes a first section 411, a sizing section 412, and a tail section 413 that are coaxially connected in sequence. In order to facilitate the smooth insertion of the enameled wire 5 into the sizing hole 41, both the first section 411 and the tail section 413 are flared. The enameled wire 5 is sizing through the sizing section 412.
[0042] Furthermore, as a preferred embodiment, the guide wheel 2, the peeling knife 3, the sizing die 4, and the peeling die 6 can all be operably adjusted in the longitudinal and longitudinal directions. The installation positions of the guide wheel 2, the peeling knife 3, the sizing die 4, and the peeling die 6 can be adapted and adjusted according to the internal structure of the wire drawing machine and the size of the enameled wire 5, thereby further improving applicability.
[0043] Furthermore, as a preferred embodiment, the frame 1 has two adjustment slots 13, which are distributed on both sides of the frame 1 in the front-back direction, and each adjustment slot 13 is longitudinally distributed.
[0044] It also includes: an adjusting screw 7, which is arranged in the front-to-back direction, with its two ends slidably installed in two adjusting grooves 13 respectively. A locking component is provided between each adjusting groove 13 and the adjusting screw 7 to lock the longitudinal position of the adjusting screw in the adjusting groove 13.
[0045] The guide wheel 2 is coaxially rotatably mounted on the outside of the adjusting screw 7 and can slide along the axial direction. A limiting component is provided between the guide wheel 2 and the adjusting screw 7 to limit the position of the guide wheel 2 on the adjusting screw 7.
[0046] Furthermore, as a preferred embodiment, the locking assembly includes two locking nuts 8, which are threaded onto the outside of the adjusting screw 7 and located on both sides of the adjusting groove 13. When the guide wheel 2 needs to be adjusted longitudinally, the adjusting screw 7 can be longitudinally slidably adjusted within the adjusting groove 13 by loosening the outer locking nut 8 in the locking assembly. After adjustment, the outer adjusting nut is tightened again, and the two locking nuts 8 clamp the inner sides of the adjusting groove 13 respectively, thereby achieving the locking effect on the adjusting screw 7.
[0047] The limiting assembly includes two limiting nuts 9, which are threaded onto the outside of the adjusting screw 7 and located on both sides of the guide wheel 2. Each limiting nut 9 is in limiting contact with the guide wheel 2. When it is necessary to adjust the position of the guide wheel 2 in the front-back direction, the two limiting nuts 9 are screwed toward the side that needs to be moved, and the guide wheel 2 slides axially on the adjusting screw 7 to adjust the front-back position of the guide wheel 2.
[0048] Furthermore, as a preferred embodiment, the frame 1 has a plurality of first mounting holes 11, a plurality of second mounting holes (not shown in the figure), and a plurality of third mounting holes 12. The plurality of first mounting holes 11, the plurality of second mounting holes, and the plurality of third mounting holes 12 are all distributed in a stepped manner along the front-back direction. The peeling knife 3 is detachably disposed in one of the first mounting holes 11, the sizing mold 4 is detachably disposed in one of the second mounting holes, and the peeling mold 6 is detachably disposed in one of the third mounting holes 12. The peeling knife 3 / sizing mold 4 / peeling mold 6 can be adjusted in the longitudinal and front-back directions by means of the first mounting holes 11 / second mounting holes / third mounting holes 12 installed at different positions.
[0049] Preferably, the peeling knife 3 is detachably installed with bolts between itself and the first mounting hole 11, the sizing mold 4 and the second mounting hole, and the peeling mold 6 and the third mounting hole 12.
[0050] Based on the above, this utility model also has the following embodiments:
[0051] More preferably, the peeling device also includes a spraying device located above the frame 1, with its outlet facing the peeling knife 3 and the peeling mold 6, for spraying the drawing fluid to cool, lubricate and clean the peeling knife 3 and the peeling mold 6.
[0052] Even better, the peeling device also includes a filter box located below the frame 1 for filtering the sprayed drawing liquid, so as to achieve reuse.
[0053] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
