Description

Technical Field

[0001] This invention relates to a production apparatus for high-strength tempered bead wire for radial tires, belonging to the field of bead wire production technology. Background Technology

[0002] Bead wire is a type of steel wire plated with bronze, copper, or brass, used to reinforce the tire bead. The bead wire and the insulating rubber form a ring that tightly secures the tire to the rim. During tire operation, the ring is subjected to tension, compression, torsion, and centrifugal force. Bead wire is an essential metal skeleton material for radial tires used in various motor vehicles and aircraft. With the continuous increase in tire production, the demand for bead wire is also increasing, and the quality requirements are becoming more stringent.

[0003] The production process of tire bead wire is as follows: coiled wire entering the site, pretreatment, primary drawing, heat treatment, secondary drawing, tempering, copper plating and packaging. Tempering refers to the process of immersing hardened or normalized steel in a temperature below the critical temperature for a period of time and then cooling it at a certain rate to increase the toughness of the material.

[0004] The utility model patent with application number CN202221503039.1 discloses a tempering device for medium-frequency tempering of tire bead wire, including a main body. The top of the main body is provided with a tempering groove and two first fixed pulleys, which are respectively arranged on the left and right sides of the tempering groove. Two second fixed pulleys are fixedly arranged at the bottom of the tempering groove, which are distributed on the left and right sides. The medium-frequency heating device is fixedly arranged on the inner wall of the tempering groove. This utility model relates to a tempering device for medium-frequency tempered tire bead wire. It collects impurities from the cooling water, preventing them from remaining on the bead wire after tempering and facilitating a higher copper plating coverage. Furthermore, by applying purified cooling water back to the bead wire, residual impurities are further removed, further improving the copper plating coverage. The reciprocating motion of the brush bristles on the bead wire, driven by a cleaning ring, further enhances the impurity removal effect. However, existing technologies leave moisture on the wire after tempering, causing water droplets to fall during movement, wasting water and impacting the production environment.

[0005] Therefore, there is a need for a production device for high-strength tempered bead wires for radial tires to remove moisture from the bead wires. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a production device for high-strength tempered bead wire for radial tires that removes moisture from the bead wire.

[0007] The technical solution adopted by the present invention to solve the above problems is as follows: a production device for high-strength tempered bead wire for radial tires, including a water tank with an opening at the top, and clean water, a heater and a water removal mechanism are provided in the water tank, with the heater and water removal mechanism arranged on the left and right sides;

[0008] The water removal mechanism includes a fixed pipe located above the clean water and parallel to the front-to-back direction. The rear end of the fixed pipe is sealed and fixedly installed on the inner wall of the rear side of the water tank. A rotating roller is coaxially installed inside the fixed pipe, and both ends of the rotating roller are rotatably connected to the fixed pipe.

[0009] Both ends of the rotating roller are coaxially fixed with rotating shafts, and a first bearing is installed on each of the two rotating shafts. The outer ring of the first bearing is fixedly connected to the fixed tube.

[0010] A fan blade is mounted on a rotating shaft located in front of the rotating roller, and the fan blade is located inside a fixed tube.

[0011] Preferably, the outer wall of the rotating roller is provided with a spiral groove around the axis of the rotating roller.

[0012] Preferably, two conduits are fixedly threaded through the fixed tube, arranged vertically, with the bottom end of the lower conduit submerged in clean water.

[0013] Preferably, both ducts are located behind the fan blade, with the lower duct positioned between the fan blade and the upper duct.

[0014] Preferably, the conduit is provided with multiple strip-shaped grooves, all of which are parallel to the conduit and are evenly distributed circumferentially on the inner wall of the conduit with the axis of the conduit as the center. The two ends of the grooves extend to the two ends of the conduit, respectively.

[0015] Preferably, a water-blocking ring is coaxially fixed at the front end of the fixed pipe. The inner diameter of the water-blocking ring is smaller than the inner diameter of the fixed pipe, and the outer diameter of the water-blocking ring is larger than the outer diameter of the fixed pipe. An air pipe is threaded through the water-blocking ring. One end of the air pipe is inserted into the ring hole of the water-blocking ring, and the other end of the air pipe is located outside the fixed pipe. The end of the air pipe away from the water-blocking ring is set downwards, and the air pipe is located above the clean water.

[0016] Preferably, the water tank is provided with a stirring mechanism, which includes a drive shaft that is parallel to the rotating shaft and located below the rotating shaft. The drive shaft is rotatably and sealed to the water tank. Multiple stirring rods are fixedly arranged on the drive shaft, and at least one of the stirring rods is inserted into the clean water. The rear end of the drive shaft is connected to the rotating shaft at the rear end of the rotating roller.

[0017] Preferably, a drive wheel is mounted on the rotating shaft at the rear end of the rotating roller, and a driven wheel is mounted at the rear end of the transmission shaft. The drive wheel and the driven wheel are connected by a transmission belt.

[0018] Preferably, the water tank is equipped with two upper rollers and two lower rollers. The two upper rollers are arranged symmetrically from left to right, and the two lower rollers correspond one-to-one with the two upper rollers. The two lower rollers are located below the two upper rollers, and both lower rollers are submerged in clean water. The heater and the two upper rollers are located above the clean water.

[0019] Preferably, a cleaning ring is provided inside the water tank. The cleaning ring is located between the lower left roller and the water removal mechanism.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] 1. The water removal mechanism removes water from the steel wire and returns the removed water to the water tank, thus preventing water from dripping from the steel wire and saving water resources;

[0022] 2. By controlling the airflow within the fixed pipe, moisture can be blown away from the steel wire, improving the water removal effect of the steel wire;

[0023] 3. By controlling the airflow inside the fixed pipe, the evaporation rate of moisture on the steel wire can be increased, further improving the dewatering effect;

[0024] 4. By controlling the airflow inside the fixed pipe, it is also convenient for the water removed from the steel wire to flow to the lower conduit and then back to the water tank.

[0025] 5. The air discharged from the fixed pipe acts on the clean water in the water tank, which helps to lower the temperature of the clean water in the tank and prevents the water temperature from being too high and affecting the tempering effect of the steel wire.

[0026] 6. The stirring mechanism agitates the water, improving the uniformity of heat distribution within the water and facilitating the absorption of heat from the steel wire, thereby enhancing the tempering effect of the steel wire. Attached Figure Description

Detailed Implementation

[0038] like Figure 1-10As shown in this embodiment, a high-strength tempered bead wire production device for radial tires includes a water tank 1 with an open top. Two upper rollers 2 and two lower rollers 3 are arranged symmetrically on the left and right sides of the water tank 1. The two lower rollers 3 correspond one-to-one with the two upper rollers 2 and are located below the two upper rollers 2. A heater 4 is installed on the inner right wall of the water tank 1. The water tank 1 is filled with clean water, and both lower rollers 3 are submerged in the water. The heater 4 and the two upper rollers 2 are located above the water. A water removal mechanism 5 is installed in the water tank 1, located between the left lower roller 3 and the left upper roller 2. A steel wire 6 enters from the right side of the water tank 1, passes sequentially around the right upper roller 2, the right lower roller 3, the left lower roller 3, and the left upper roller 2, and exits, ending at the right upper roller. 2. The steel wire 6 of the right lower roller 3 passes through the heater 4, while the steel wire 6 located between the two lower rollers 3 is immersed in clean water. The heater 4 heats the steel wire 6. When the steel wire 6 is immersed in clean water, it is tempered. The steel wire 6 located between the left lower roller 3 and the left upper roller 2 is cleaned by the water removal mechanism 5, and the clean water is returned to the water tank 1. In addition, a cleaning ring 7 is set between the water removal mechanism 5 and the left lower roller 3. The axis of the cleaning ring 7 is vertically set. The cleaning ring 7 is fixedly connected to the inner wall of the water tank 1. The inner wall of the cleaning ring 7 is covered with bristles 8. The steel wire 6 passes around the left lower roller 3, passes through the cleaning ring 7, and abuts against the bristles 8. As the steel wire 6 moves, the bristles 8 brush off the impurities on the cleaning ring 7 to prevent impurities from affecting the copper plating effect in the subsequent copper plating process.

[0039] The water removal mechanism 5 includes a fixed pipe 501, which is located above the clean water and is parallel to the front-to-back direction. The rear end of the fixed pipe 501 is sealed and fixedly installed on the inner wall of the rear side of the water tank 1. A rotating roller 502 is coaxially arranged inside the fixed pipe 501, and both ends of the rotating roller 502 are rotatably connected to the fixed pipe 501. Two guide tubes 503 are fixedly inserted through the fixed pipe 501, arranged vertically. The guide tubes 503 are vertically arranged, and the steel wire 6 that passes around the lower left roller 3 passes through the lower guide tube 503 and enters the fixed pipe 501. The steel wire 6 inside the fixed pipe 501 is threaded. After being wound around the fixed tube 501, the wire 6 passes through the upper guide tube 503. During the movement of the traction wire 6, the rotating roller 502 is driven to rotate around its own axis by friction. In this way, the wire 6 in the lower guide tube 503 continues to be wound around the rotating roller 502, while the wire 6 on the rotating roller 502 continues to pass through the upper guide roller. In addition, the rotation of the rotating roller 502 drives the wire 6 wound on the rotating roller 502 to rotate synchronously. Under the action of centrifugal force, the water on the wire 6 wound on the rotating roller 502 is separated from the wire 6, thus achieving the removal of water from the wire 6. The removed water then flows back to the water tank 1 from the lower guide tube 503.

[0040] The inner diameter of the conduit 503 is equal to the diameter of the steel wire 6. The conduit 503 has multiple strip-shaped grooves 504, all parallel to the conduit 503. These grooves are evenly distributed circumferentially on the inner wall of the conduit 503, with the axis of the conduit 503 as the center. The two ends of each groove extend to both ends of the conduit 503, facilitating the passage of air or water through the conduit 503.

[0041] Both ends of the rotating roller 502 are coaxially fixed with rotating shafts 505, and both rotating shafts 505 are equipped with first bearings 506. The outer ring of the first bearing 506 is fixedly connected to the fixed tube 501.

[0042] A fan blade 507 is mounted on a rotating shaft 505 located in front of the rotating roller 502. The fan blade 507 is located inside the fixed tube 501. A lower guide tube 503 is located in front of the upper guide tube 503, and the fan blade 507 is located in front of the lower guide tube 503. The bottom end of the lower guide tube 503 is submerged in clean water. The rotation of the rotating roller 502 drives the rotating shaft 505 to rotate on the first bearing 506, and the rotation of the rotating shaft 505 drives the fan blade 507 to rotate. Through the rotation of the fan blade 507, the fan blade 507 inside the fixed tube 501 rotates. The air is discharged from the front end of the fixed tube 501, while the air outside the fixed tube 501 is transported into the fixed tube 501 from the upper conduit 503. Through the flow of air in the fixed tube 501, not only can the water be blown away from the steel wire 6, improving the water removal effect of the steel wire 6, but also the evaporation rate of the water on the steel wire 6 can be increased, further improving the water removal effect of the steel wire 6. In addition, through the flow of air, the water removed from the steel wire 6 can also flow back to the water tank 1 through the lower conduit 503.

[0043] A water-blocking ring 508 is coaxially fixed at the front end of the fixed pipe 501. The inner diameter of the water-blocking ring 508 is smaller than the inner diameter of the fixed pipe 501, and the outer diameter of the water-blocking ring 508 is larger than the outer diameter of the fixed pipe 501. An air pipe 509 is threaded through the water-blocking ring. One end of the air pipe 509 is inserted into the annular hole of the water-blocking ring 508, and the other end of the air pipe 509 is located outside the fixed pipe 501. The end of the air pipe 509 away from the water-blocking ring is set downward. The air pipe 509 is located above the clean water. The air in the fixed pipe 501 is discharged from the air pipe 509 and acts on the clean water, thereby facilitating the reduction of the clean water temperature in the water tank 1 and preventing the clean water temperature from being too high and affecting the tempering effect of the steel wire 6.

[0044] The outer wall of the rotating roller 502 is provided with a spiral groove 510 around the axis of the rotating roller 502. When the steel wire 6 is wound on the rotating roller 502, it is stuck in the spiral groove 510, thereby increasing the contact area between the steel wire 6 and the rotating roller 502, improving the reliability of pulling the rotating roller 502 to rotate when the steel wire 6 is pulled, and also serving as a guide for the steel wire 6 wound on the rotating roller 502.

[0045] The water tank 1 is also provided with a stirring mechanism 9, which is connected to the rotating shaft 505 at the rear end of the rotating roller 502.

[0046] The stirring mechanism 9 includes a drive wheel 901 and a driven wheel 902. A rotating shaft 505 at the rear end of the rotating roller 502 passes through the rear side of the water tank 1. The rotating shaft 505 at the rear end of the rotating roller 502 is rotatably and sealed to the water tank 1. The drive wheel 901 is mounted on the rotating shaft 505 at the rear end of the rotating roller 502. The drive wheel 901 is located at the rear side of the water tank 1. A transmission shaft 903 passes through the rear side of the water tank 1. The transmission shaft 903 is parallel to the rotating shaft 505 and is located below the rotating shaft 505. The transmission shaft 903 is rotatably and sealed to the water tank 1. The transmission shaft 903 is rotatably connected to the water tank 1 via a second bearing 904. The driven gear is mounted at the rear end of the transmission shaft 903. The drive wheel 901 and the driven wheel 902... 2. A plurality of stirring rods 905 are fixedly mounted on the transmission shaft 903 via a transmission belt 906. The stirring rods 905 are evenly distributed circumferentially around the axis of the transmission shaft 903. The transmission shaft 903 is located above the clean water, and each stirring rod 905 is located in the water tank 1. At least one stirring rod 905 is inserted into the clean water. The rotation of the rotating shaft 505 drives the drive wheel 901 to rotate. The rotation of the drive wheel 901 drives the driven wheel 902 to rotate via the transmission belt 906. The rotation of the driven wheel 902 drives the transmission shaft 903 to rotate on the second bearing 904. The rotation of the transmission shaft 903 drives the stirring rods 905 to rotate, thereby stirring the clean water with the stirring rods 905. This can improve the uniformity of heat distribution in the clean water, making it easier for the clean water to absorb the heat from the steel wire 6 and improve the tempering effect of the steel wire 6.
