    Carbon Steel Galvanized Black Oxidation DIN Flange Welding Nuts

    Carbon Steel Galvanized Black Oxidation DIN Flange Welding Nuts.


    Description

    The cold heading process is one of the new processes of metal pressure machining with little and no cutting. It is a processing method that uses the plastic deformation generated by the metal under the action of external force, and with the help of the mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of standard fasteners such as bolts, screws, nuts, rivets, and pins.


    Operation process of black oxidation treatment:
    Workpiece clamping → degreasing → cleaning → pickling → cleaning → oxidation → cleaning → saponification → hot water boiling and washing → inspection.


    (1) Workpiece clamping: According to the shape and size of the work piece, a special fixture or spreader should be designed. The purpose is to leave enough gaps between the workpieces, the workpieces cannot contact each other, so that each workpiece can be completely immersed in the oxidizing solution to be oxidized.


    (2) Degreasing: The purpose is to remove oil stains on the surface of the workpiece. After machining (bluing and blackening is the last process), the surface of the workpiece will inevitably not leave oil stains. This is especially true when using anti-rust oil for inter-process anti-rust. Any oil pollution will seriously affect the formation of ferroferric oxide, so it must be removed before turning blue and black.
