Abstract

The invention discloses a surface treatment device for high-strength anti-slide wheel hub bolts. The surface treatment device comprises a pickling tank, a pickling basket, two pickling basket moving devices, a control panel, a cross bar and a pickling basket hanging bracket; the pickling tank is a rectangular tank; the upper end of the pickling tank is transversely provided with the pickling basket moving devices in the long edge direction of the pickling tank; the two pickling basket moving devices are symmetrically arranged on the side edges of the two sides of the upper end of the picklingtank correspondingly; and the cross bar is arranged between the two pickling basket moving devices. The pickling basket moving devices are arranged at the upper end of the pickling tank, the picklingbasket and the bolts in the basket can be driven by the pickling basket moving devices to reciprocally move laterally in the long edge direction of the pickling tank and move up and down, the picklingbasket moving devices drive the bolts to be pickled, cleaned and drained automatically, thus, the pickling efficiency is improved, the pickling quality is improved, the labor intensity of workers isrelieved, and the production cost is reduced.

Description

【Technical field】

[0001] The invention relates to the technical field of fastener production, in particular to the technical field of bolt pickling equipment. 【Background technique】

[0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. In the bolt production process, in order to improve the anti-rust and anti-corrosion properties of the bolt surface, the surface of the bolt is often treated. Pickling is a method of bolt surface treatment. Pickling uses acid solution to remove scale and rust on the steel surface. The method is called pickling. It is a method of cleaning metal surfaces. Generally, the workpiece is immersed in an aqueous solution such as ...
