Technical Field

[0001] The utility model relates to the technical field of galvanizing devices in bolt manufacturing, in particular to a bolt galvanizing turning device. Background Art

[0002] When bolts are manufactured, in order to make them anti-corrosion, anti-rust and beautiful, they need to be galvanized on the surface. When galvanizing the bolts, first put them in a pickling tank to remove impurities such as oil, rust and oxide scale on the surface, clean the surface of the bolts with an acid solution to remove rust and other impurities, preheat the bolts and then put them in a galvanizing tank to coat the surface of the bolts with a layer of zinc. The corrosion resistance of the galvanized bolts can be greatly improved.

[0003] In traditional bolt galvanizing work, bolts are placed in containers, and the containers are placed in zinc liquid by a mechanical arm or hanger so that the outer surface of the bolts contacts the zinc liquid, thereby achieving galvanizing. However, during the galvanizing process, the container used to store the bolts is stationary, and the internal bolts are not moving. During the galvanizing process, the zinc liquid is not easy to enter the gaps between the bolts or between the contact surfaces of the two bolts, which leads to incomplete galvanizing of the bolts and local galvanizing leakage.

[0036] In the disclosed embodiment, the balancing frame 6 is a "U"-shaped structure, and two hanging support plates 601 are welded in the middle of the upper surface of the balancing frame 6, and the two hanging support plates 601 are fixedly installed with a hanging shaft 602 by interference fit; the rotating support shaft 7 is supported by the balancing frame 6 and the horizontality of the rotating support shaft 7 is maintained, and a unloading driven support wheel 603 is installed on the hanging shaft 602 by interference fit, and the unloading driven support wheel 603 is meshed and connected with the unloading active gear 501 to form a gear transmission; after the galvanizing is completed, when the bolts are taken out from the inside of the galvanized rotary hopper 8, the unloading drive member 5 is controlled to move, and the unloading drive member 5 drives the unloading active gear 501 to rotate, and the unloading active gear 501 drives the unloading driven support wheel 603 to rotate, so that the balancing frame 6 as a whole tilts to the lower right, and the opening of the galvanized rotary hopper 8 tilts to the lower right, so that the bolts inside the galvanized rotary hopper 8 are unloaded from the opening.
