The embodiment specifically discloses a but self-aligning's flat varnished wire is with painting device, as shown in fig. 1, including die carrier 1 and mould 2, set up U type groove 121 on the die carrier 1, as shown in fig. 1, die carrier 1 includes riser 11 and perpendicular to riser 11 fixed diaphragm 12, and U type groove 121 sets up on diaphragm 12, and riser 11 is kept away from to the opening direction of U type groove 121, and die carrier 1 is used for supporting mould 2. The die carrier 1 and the die 2 of the embodiment are applied to a vertical enamelled wire production line.
As shown in fig. 1 to 3 and 5, the die 2 comprises a die sleeve 21 and a sizing die 22, wherein the die sleeve 21 comprises a counterweight section 211, a limiting section 212, an adjusting section 213 and a drainage section 214 which are sequentially arranged from top to bottom along the axial direction; as shown in fig. 3 and 5, the sizing die 22 is detachably sleeved in the inner cavity of the counterweight section 211, and most of the weight of the die 2 is concentrated in the counterweight section 211, so that the die 2 is balanced on the die frame 1 during painting. The sizing die 22 is internally provided with a paint coating hole which is coaxial with the die sleeve 21 and is communicated with the inner cavity of the die sleeve 21, and the inner cavity of the die sleeve 21 and the paint coating hole form a passing cavity for the wire rod 3 to pass through. The external diameter of the counterweight section 211 is greater than the opening width of the U-shaped groove 121, the external diameter of the limiting section 212 is smaller than the opening width of the U-shaped groove 121 and is used for being clamped into the U-shaped groove 121, the adjusting section 213 is a hemisphere with a downward sphere center, as shown in fig. 4, grooves matched with the spherical surface of the adjusting section 213 are formed in the inner wall of the U-shaped groove 121 of the die carrier 1 and the bottom wall of the U-shaped groove 121 (namely the bottom wall of the transverse plate 12), and the length of the limiting section 212 is greater than the height from the top of the groove to the top of the U-shaped groove 121.
Before painting, the limiting section 212 is clamped into the U-shaped groove 121 of the die carrier 1, and the bottom end surface of the counterweight section 211 is contacted with the top of the transverse plate 12. When painting, the wire 3 enters the passing cavity of the die 2 from the bottom end of the drainage section 214 of the die 2, the wire 3 travels upwards, and the wire 3 extends out of the die 2 from the top end inner cavity of the counterweight section 211. The wire 3 can exert ascending power to mould 2 when upwards advancing, simultaneously, mould 2 self gravity can produce the pressure that is down all the time, mould 2 upwards floats under the combined effort of the drag force that wire 3 upwards advanced produced and mould 2 dead weight, be the suspension state as shown in fig. 3 and 5, at this moment, the regulating section 213 of die sleeve 21 and the recess contact of U type groove 121, regulating section 213 can play universal regulation's effect, according to the transmission direction and the skew angle mould 2 automatic rotation aligning of wire 3, make the central line of mould 2 and the central line of wire 3 keep unanimous, keep the concentricity of mould 2 and wire 3, avoid the condition emergence of overmould broken wire, and reduce the eccentric rate of flat enameled wire for the japanning is even.

In some embodiments, the bottom end inner cavity diameter of the drainage section 214 is greater than or equal to the top end inner cavity diameter of the drainage section 214, so that better drainage effect is achieved, and paint liquid in the drainage section 214 better enters the adjusting section 213, the limiting section 212, the counterweight section 211 and the painting holes to be painted uniformly. More preferably, the drainage segment 214 has a lumen diameter that gradually decreases from bottom to top.
In some embodiments, the drainage segment 214 is a cylinder (as shown in fig. 3), a truncated cone (as shown in fig. 5), or a trapezoid, and serves as a drainage while naturally transitioning with the conditioning segment 213.
As shown in fig. 3 and 5, the diameter of the inner cavity of the adjusting section 213 gradually decreases from the bottom to the top, so that the paint liquid is ensured to smoothly flow into the limiting section 212 from the drainage section through the adjusting section 213. More preferably, the shape of the cavity of the adjustment section 213 is the same as the shape of the exterior of the adjustment section 213.
As shown in fig. 3 and 5, the inner peripheral surface of the counterweight section 211 is provided with a step for embedding the sizing die 22, and the step is closer to the top end of the counterweight section 211, so that the sizing die 22 and the painting hole are far away from the die frame 1 as far as possible, the automatic deflection of the die 2 is facilitated, and the concentricity of the paint layer and the adjustment of the painting amount during painting are ensured.
As shown in fig. 3 and 5, the diameter of the inner cavity of the die sleeve 21 gradually decreases from the bottom end of the limit section 212 to the step of the counterweight section 211 to form a truncated cone-shaped die cavity, which can play a good role in guiding paint liquid and correcting the paint liquid on the surface of the wire 3. Preferably, the aperture of the bottom end of the paint hole is the same as the diameter of the step in the inner cavity of the counterweight segment 211, and the aperture of the paint hole gradually decreases from the bottom end to the top end. The diameter of the top end of the lacquering hole is slightly larger than the outer diameter of the wire 3. After the drainage section 214, the diameter of the cavity of the die sleeve gradually decreases from the adjusting section 213 to the top end of the paint hole (i.e. the outlet of the paint hole), and the paint liquid is continuously corrected on the surface of the wire rod 3 while being drained, and finally, a uniform paint layer with proper thickness is formed on the surface of the wire rod 3 through the treatment of the outlet of the paint hole. The thickness of the paint is defined by adjusting the size of the paint aperture.
