Description

Technical Field

[0001] The utility model relates to the technical field of bolt production, in particular to a hot-dip galvanizing device for bolt production. Background Art

[0002] During the production process, bolts need to be galvanized to prevent corrosion. In existing bolt galvanizing equipment, zinc liquid splashes easily when the bolts are immersed in zinc liquid, and the bolts are stacked together for galvanizing during hot-dip galvanizing. This method easily causes the contact parts of the bolts to fail to be fully galvanized, resulting in poor bolt quality.

[0003] Chinese Patent: CN219490124U, which discloses a hot-dip galvanizing device for bolt production, the device puts the bolts into the blanking plate through the blanking port, and the blanking plate is tilted so that the bolts roll down naturally, so that the bolts are galvanized during the rolling process, and then fall into the pulling box for collection, and further galvanized, so that the surface of the bolts is completely galvanized, avoiding galvanizing when the bolts are piled together, and after galvanizing, excess zinc liquid will remain on the surface of the bolts, and the bolts need to be cooled to prevent the staff from being scalded when taking the bolts. After the galvanizing is completed, the above-mentioned device will keep the pulling box away from the zinc liquid and let it stand for a period of time inside the galvanizing box. After the zinc liquid drips, the storage box is placed across the upper end of the pull-out groove, and then the pulling box is rotated to pour out the bolts to complete the work. In actual use, the standing process will waste a lot of time, and during the standing process, due to the high temperature inside the galvanizing box, the temperature of the bolts cannot be reduced, and the bolts need to be cooled separately, which will affect the work efficiency.

[0004] Based on this, a hot dip galvanizing device for bolt production is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

When in use, when the output end of the hydraulic rod 22 drives the rotating box 21 to move so that the first friction wheel 23 is closely attached to the friction rod 24, the upper end of the push plate 25 is closely attached to the sliding plate 29. When the hydraulic rod 22 continues to move, the push plate 25 pushes the sliding plate 29 to slide along the axial direction of the guide slide rod 30, and at the same time, the sliding plate 29 drives the second rack 32 to move. The wheel 33 rotates, and the second gear 33 drives the moving box 26 to slide along the length direction of the first guide groove rod 19 through the first mounting shaft, the second friction wheel, the third friction wheel 34, the fifth friction wheel and the friction plate 28. When the bolts inside the rotating box 21 begin to fall, the moving box 26 moves to the bottom of the rotating box 21, so that the bolts fall into the inside of the moving box 26, and then the output end of the hydraulic rod 22 drives the rotating box 21 back to the initial position so that, under the action of the reset spring 31, the second rack 32 returns to the initial position, and the moving box 26 also returns to the initial position.

[0035] The above embodiment discloses a hot-dip galvanizing device for bolt production, wherein when the bolts need to be galvanized, the bolts are placed inside the feeding box 13, and then the electric push rod 16 is started. The output end of the electric push rod 16 drives the first rack 15 to move, and the first rack 15 is meshed with the first gear 14 to rotate the feeding box 13. When the feeding box 13 rotates, the bolts inside the feeding box 13 fall to the upper end of the unloading plate 17, and are guided by the guide plate 18 so that the bolts fall into the rotating box 21. After the bolts are galvanized, the hydraulic rod 22 is started, and the output end of the hydraulic rod 22 drives the rotating box 21 to move through the fixed shaft. When the first friction wheel 23 moves to one end of the friction rod 24, the first friction wheel 23 is tightly attached to one side of the friction rod 24, and at the same time, the upper end of the push plate 25 is tightly attached to the sliding plate 29. When the output end of the hydraulic rod 22 continues to drive the rotating box 21 to move, the first friction wheel 23 and the friction rod 24 rotate by friction, so that ...

When the bolts inside the rotating box 21 begin to fall, the moving box 26 moves to the bottom of the rotating box 21, so that the bolts fall into the inside of the moving box 26, and then the output end of the hydraulic rod 22 drives the rotating box 21 back to the initial position so that, under the action of the reset spring 31, the second rack 32 returns to the initial position, and the moving box 26 also returns to the initial position. Then, the excess zinc liquid on the surface of the bolt falls to the upper end of the liquid guide plate 37 through several filter holes at the bottom of the moving box 26, so that the zinc liquid flows back into the galvanizing box 11, and the cooling fan 36 is started at the same time. Several cooling fans 36 are convenient for cooling the bolts.
