Description

Technical Field

[0001] The utility model belongs to the technical field of cast iron bolt processing, in particular to a cast iron bolt coating device. Background Art

[0002] Cast iron bolts are a common connection element, widely used in mechanical equipment, railways, bridges, construction and other fields. They are mainly made of cast iron, and bolts are cylindrical threaded fasteners, consisting of a head and a screw. They need to be used with nuts to fasten two parts with through holes. This type of connection is called bolt connection. During the processing of cast iron bolts, it is usually necessary to coat the surface of the bolts to increase rust and corrosion resistance.

[0003] The utility model patent with patent application publication number 202321768737.9 discloses a bolt coating device, which specifically relates to the field of bolt coating technology, including a C-type plate. Through the rotating device, the rubber sleeve drives the bolt body to rotate through friction, and then drives the magnet column to rotate. The bolt body rotates and the external dust is adsorbed, achieving all-round cleaning and improving the effect of later coating of the bolt body. The rotating device can also be used to coat the bolt body in all directions, and the spraying is more uniform and delicate.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that when coating bolts of different sizes, the distance between the rubber sleeves on the outer column used to clean the bolts is not easy to adjust. Smaller bolts cannot be supported, and larger bolts are not easy to drive to rotate, thereby reducing the cleaning and spraying effect of the bolts. For this reason, we propose a cast iron bolt coating device. Utility Model Content
