The invention provides a wheel check ring machining method and a cold pressing mold. The cold pressing mold comprises a male mold and a female mold, wherein the top end of the male mold is provided with a protruding part, the outer side of the protruding part is sleeved with the bottom end of a blank to be pressed, and the thickness of the side wall of the bottom end of the blank to be pressed islarger than that of the side wall of the top end of the blank to be pressed; and the bottom end of the female mold is provided with a groove, the protruding part can completely extend into the groove,and after the protruding part completely extends into the groove, the blank to be pressed on the outer side of the protruding part is pressed into a preset shape. In this way, by adopting the specialvehicle check ring cold pressing mold, the machining efficiency and the machining precision are improved, only one person is needed to carry out operation in the turning process, labor is saved, electricity and the labor cost are reduced, the trapezoid blank with one end being relatively thin and the other being relatively thick is cold pressed into a shape, the relatively thin part is thickenedafter cold pressing forming, the standard requirement can be met, the machining allowance is reduced, and the turning efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for processing a wheel retaining ring and a cold pressing die. Background technique [0002] With the ever-changing scientific and technological progress, the development of engineering vehicles has also been greatly improved. As an important tool to improve people's engineering operations, engineering vehicles have become increasingly indispensable.
