摘要： A method for manufacturing a hollow engine valve includes inserting a half-finished hollow shaft section in sequence into die holes which have different hole shapes, and sequentially drawing so as to reduce the outer diameter and the inner diameter of the hollow shaft section and stretch its length in stages. The half-finished product is subjected to heat treatment so that the hardness thereof is lower than or equal to a predetermined level. A shaft end sealing section is formed by increasing the wall thickness of the opening end of the hollow shaft section toward the inside of the opening and the gap in the shaft end sealing section is welded.

摘要： A method for manufacturing a hollow engine valve includes a step for performing rotational plastic working on a follow engine valve body semifinished product which is configured from a shaft part and a valve umbrella part forming portion connected to the shaft part. A columnar hole part is formed from the shaft part to an enlarged diameter section of the valve umbrella part forming portion to thereby reduce the diameter of the shaft part. A necking step follows the rotational plastic working step, necking the hollow engine valve body semifinished product to thereby reduce the outer diameter and the inner diameter of the shaft part. A sealing step seals the leading end of the shaft part to obtain the hollow engine valve.
