[0002] Bead wire is a bronze, copper or brass plated steel wire used to strengthen the tire bead. The wire ring made of bead wire and insulating rubber fixes the outer tire tightly on the rim. The wire ring is subjected to tension, compression, torsion and centrifugal force during the running of the tire.

[0040] S1, 24 round coils of tire bead wire enter the venue;

[0041] S2, pretreatment: the surface of the bead wire 24 raw material is coated and then dried, and the coating is oxalate;

[0042] S3, primary drawing: drawing the bead wire 24 by a first wire drawing machine;

[0043] The diameter of the tire bead wire 24 is reduced by drawing, and talcum powder is applied to the tire bead wire 24 during the drawing process to reduce the friction between the tire bead wire 24 and the drawing die.

[0044] S4, heat treatment: using a muffle furnace to heat the tire bead wire 24, and using lead bath quenching for cooling;

[0045] The muffle furnace has stable control, low labor intensity, and lead bath quenching can obtain uniform and fine troostite structure.

[0046] S5, secondary drawing: drawing the bead wire 24 by a second wire drawing machine;

[0047] The diameter of the tire bead wire 24 is reduced by drawing again. During the drawing process, talcum powder is applied to the tire bead wire 24 to reduce the friction between the tire bead wire 24 and the drawing die.

[0048] S6, medium frequency tempering:

[0049] a. The bead wire 24 enters the tempering device, is heated by the medium frequency heating device 1, and then is cooled by cooling water;

[0050] b. Collect impurities in the cooling water through the impurity collection device, and remove impurities on the tire bead wire 24 after cooling;

[0051] The bead wire 24 is heated by the medium frequency heating device 1, and then enters the cooling water for cooling to complete tempering, and the impurities in the cooling water are collected by the impurity collecting device to purify the cooling water to prevent the impurities from remaining on the bead wire 24. In addition, the purified cooling water acts on the bead wire 24 leaving the cooling water again, which not only further improves the cooling effect, but also can flush the impurities on the bead wire 24, further preventing the impurities from remaining on the bead wire 24.

[0052] Table 1: Relationship between bead wire length and number of residual impurity particles when impurities in cooling water are not collected

[0053] Bead wire 24 meters long 500 1000 1500 2000 2500 3000 3500 Number of impurity particles 10 18 29 38 47 58 6

[0054] Table 2: Relationship between the length of bead wire and the number of residual impurity particles after impurities are collected in cooling water

[0055] Bead wire 24 meters long 500 1000 1500 2000 2500 3000 3500 Number of impurity particles 1 1 1 2 2 2 2

[0056] By comparing the data in Table 1 and Table 2, it can be concluded that after the impurities in the cooling water are collected, the number of residual impurity particles is reduced, thereby improving the coverage rate of the tire bead wire 24 during copper plating.

At the same time, cooling water is added into the tempering tank 3, and the medium frequency heating device 1 is located above the cooling water, and the second fixed pulley 5 is located in the cooling water. The tire bead wire 24 is heated by the medium frequency heating device 1 and then enters the cooling water, so that the cooling water absorbs the heat on the tire bead wire 24, and the tire bead wire 24 is tempered.

[0061] Preferably, the impurity collecting device includes an impurity collecting component and a cleaning component, the impurity collecting component includes a water collecting box 6, the top of the water collecting box 6 is open, the water collecting box 6 is fixedly arranged on the inner wall of the tempering tank 3, a water pipe 7 is arranged on the water collecting box 6, the water pipe 7 is vertically fixed and sealed to pass through the water collecting box 6, a water pump 8 is installed at the bottom end of the water pipe 7, a rotating ring 9 is arranged on the water pipe 7, the rotating ring 9 is coaxially arranged with the water pipe 7, the water pipe 7 passes through the rotating ring 9, and the rotating ring 9 It is slidably and sealedly connected to the water pipe 7, the rotating ring 9 is located above the water collecting tank 6, and a plurality of filter holes 10 are provided on the rotating ring 9, and the plurality of filter holes 10 are evenly distributed circumferentially around the axis of the water pipe 7.

Impurities are transported to the top of the rotating ring 9 by the flow of cooling water, and the water on the top of the rotating ring 9 passes through the filter 11 and flows into the water collecting tank 6, and the impurities are retained by the filter 11, thereby collecting impurities in the cold water, purifying the cooling water, and preventing impurities from remaining on the bead wire 24. The water in the water collecting tank 6 flows back to the tempering tank 3 from the water drop hole 25, and in fact, the bead wire 24 removed from the cooling water vertically passes through the water drop hole 25. The purified cooling water is then applied to the tire bead wire 24 again, so that the cooling water flushes the impurities on the tire bead wire 24, further preventing the impurities from remaining on the tire bead wire 24. In addition, the flushing effect of the tire bead wire 24 is improved by the cleaning component, and the flow of cooling water in the water pipe 7 is used as a driving force to drive the rotating unit to drive the rotating ring 9 to rotate around the axis of the water pipe 7, so that the impurities trapped on the filter screen 11 are moved horizontally away from the water pipe 7 under the action of centrifugal force and separated from the filter screen 11, thereby preventing the filter screen 11 from being blocked. In addition, by dropping the cooling water into the water collecting tank 6, the contact area between the cooling water and the air can be increased, thereby facilitating the cooling water to absorb the heat of the tire bead wire 24, that is, to reduce the temperature of the cooling water, thereby improving the cooling effect of the tire bead wire 24.

[0066] The function of the auxiliary pipe 15 is to prevent impurities from falling off the rotating ring 9 when moving away from the water pipe 7, thereby preventing the impurities from entering the cooling water again.

[0067] Preferably, the bottom end of the auxiliary pipe 15 is located in the water collecting tank 6 , and a gap is provided between the bottom end of the auxiliary pipe 15 and the bottom of the water collecting tank 6 .

[0068] This prevents the water discharged from the bottom end of the auxiliary pipe 15 from splashing under the action of centrifugal force and failing to fall into the water collecting tank 6 .

[0071] The rotation of the rotating ring 9 drives the lifting tube 17 to lift and reciprocate through the transmission unit, and the reciprocating lifting of the lifting tube 17 drives the cleaning ring 18 to lift and reciprocate. Here, the cooled tire bead wire 24 passes through the cleaning ring 18, the lifting tube 17 and the fixed tube 16 from bottom to top in sequence, and the cooling water in the water collecting tank 6 flows downward from the fixed tube 16, the lifting tube 17 and the cleaning ring 18 in sequence, so that the cleaning ring 18 drives the bristles 19 to lift and reciprocate on the tire bead wire 24, so that the bristles 19 brush off the impurities remaining on the tire bead wire 24, thereby improving the impurity removal effect.

[0074] The rotation of the rotating ring 9 drives the second magnet block 23 to rotate synchronously, and in fact, the bottom of the second magnet block 23 is the same as the top of the first magnet block. Through the principle of like charges repelling each other, the first magnet block 21 is pushed downward, and when the second magnet block 23 rotates and the distance between it and the first magnet block 21 decreases, the thrust received by the first magnet block 21 is less than the elastic force generated by the spring 22, so that the first magnet block 21 rises, and through calculation, the first magnet block 21 is always located below the second magnet block 23, as the second magnet block 23 continues to rotate, the distance between the second magnet block 23 and the first magnet block 21 decreases, and through calculation, the thrust received by the first magnet block 21 is greater than the elastic force of the spring 22, so that the first magnet block 21 descends and the spring 22 is compressed, and so on and so forth, so that the first magnet block 21 is reciprocated and lifted, and the reciprocating lifting of the first magnet block 21 drives the lifting tube 17 to reciprocate and lift synchronously through the lifting rod 20.
