Background

A bolt is a cylindrical threaded fastener matched with a nut, a fastener composed of a head part and a screw (a cylinder with external threads) needs to be matched with the nut and is used for fastening and connecting two parts with through holes, the connection form is called bolt connection, if the nut is screwed off from the bolt, the two parts can be separated, so the bolt connection belongs to detachable connection, water wax is a lubricant for dissolving a friction reducing agent in a water-based carrier, after the water-based carrier is coated on the surface of a workpiece, the water-based carrier in the water wax is removed through heating and baking, the surface of the workpiece to which the friction reducing agent is attached is enabled to play a role in reducing friction and lubricating, at present, most automobile part assembly plants adopt an automatic production mode during production, wherein the bolt adopts automatic feeding before installation, which brings a problem, the surface of the phosphated bolt is soaked in anti-rust oil, some do not, but all will be through same automatic feeding line material loading, so the material loading line is difficult to avoid having the residue of antirust oil, when having oily/oilless bolt to switch at every turn, all will spend a large amount of manpowers and material resources and wash the material loading line, not only waste time and energy, the manufacturing cost of enterprise has also been increased undoubtedly, antirust oil except can improving anticorrosive ability, the most important function is the coefficient of friction (lubricating function) of stabilizing the bolt, and coefficient of friction is the important guarantee factor of clamp force among the bolt-up process.

Most of bolt workpieces in the current market are difficult to ensure the friction coefficient of the bolt on the premise of not soaking oil, so that the stable quality of the bolt workpieces in the application process is difficult to ensure, and the service life of the bolt is inconvenient to ensure.
