不銹鋼薄壁小直徑管材拉伸加工的研究與應(yīng)用

Research on and Application of Drawing Process for Small-sized Light Wall Stainless Steel Tubing

摘要: 隨著我國科學(xué)技術(shù)的發(fā)展,不銹鋼薄壁小直徑焊管的市場缺口越來越大,每年都需從國外進(jìn)口,這顯然不符合我國國情。因此,研制高質(zhì)量的不銹鋼薄壁小直徑焊管,是當(dāng)前形勢的需要。介紹了不銹鋼薄壁小直徑焊管的拉伸工藝?yán)碚?并對管材拉伸及模具使用進(jìn)行了分析和探討,進(jìn)而對游動芯頭的應(yīng)用,提出了改進(jìn)工藝和提高管材質(zhì)量的措施。

Abstract: Along with the domestic S &T development,the supply gap of small-sized,light wall stainless steel weld tubing in the market is getting bigger and bigger,resulting in a considerable yearly import amount of such kind of product,which is not in compliance with the economic reality of the country.Therefore it turns out that considering the current domestic situation,it is a must to focus on developing small-sized,light wall stainless steel weld tubing.Described here are the theory of drawing process for small-sized,light wall stainless steel weld tubing,and a discussion on pipe-drawing operation and the dies and tooling used,based on which measures are proposed for a more effective use of the floating plug in the manufacturing process and for enhancing product quality as well.
