    鑄造法生產(chǎn)內(nèi)外水冷穿孔頂頭

    MANUFACTURE PROCESS OF CASTING FOR EXTERNALLY/INTERNALLY WATER-COOLED PIERCING PLUG

    • 摘要: 分析了3Cr2W8V鋼模鍛頂頭的現(xiàn)狀。介紹了鑄造內(nèi)外水冷穿孔頂頭的材質(zhì)、結(jié)構(gòu)形式和生產(chǎn)工藝流程,對模鍛法和鑄造法生產(chǎn)頂頭的制造成本進(jìn)行了對比。使用表明,鑄造內(nèi)外水冷穿孔頂頭的成本低,使用壽命長,生產(chǎn)工藝易掌握,值得推廣應(yīng)用。

       

      Abstract: The author provides an investigation of the currently used die-forged piercing plug made of 3Cr2W8V Steel and an introduction about the cast externally/internally water-cooled piercing plug involving such main aspects as material, structure and manufacture process flow.Compared with the die-forging process, the casting process is more cost effective.And so far as the said cast plug is concerned, relevant operational practice has proven that this kind of plug is in possession of advantages namely, lower cost, longer service life and being easy to make.It is worth spreading.
