Abstract
A car steel ring spoke production and manufacture process and a mould. Steps of the manufacture process are feeding, curling, flattening, butt welding, deslagging, flat-rolling, end-cutting, re-curling, closing, expanding, plane pressing, punching, spinning-pressing molding, air hole punching, hole reaming, machine tool finishing, labeling, inspecting, packing, warehousing and the like. Moulds used in closing, expanding and plane pressing are a closing-specific mould and a flaring-specific mould. An upper part of a blank is first pressed and shrunk to form an upper horn mouth using methods of hot forging and hot pressing or cold forging and cold pressing, and a lower part of the blank is then pressed and expanded to a horn mouth using the methods of hot forging and hot pressing or cold forging and cold pressing. The upper part is pressed into a plane. Closing can be performed once or twice. After closing, an included angle between an inclined plane of the upper horn mouth and a horizontal plane is 150-160 degrees. Through expanding and plane pressing procedures, an included angle between inclined planes of the upper horn mouth and the lower horn mouth and the horizontal plane finally becomes 110-150 degrees. The mould comprises a specific closing/flaring mould, a specific re-combing mould and/or a specific plane pressing mould. The production and manufacture process and the mould can improve a utilization rate of steel, reduce a production cost of the spoke and improve competitiveness of a product in a market.
