Abstract

本实用新型公开了一种顶头,它包括顶头本体(2);所述的顶头本体(2)顶部设有复合高温合金头(1)。本实用新型的优点在于:在穿孔过程中不易发生磨损、坍塌变形等现象,从而可大大提高顶头的使用寿命。

Description

顶头
技术领域:
本实用新型涉及一种用于轧制无缝钢管的顶头。
背景技术:
在无缝钢管生产过程中,均采用顶头对管坯进行穿孔。由于顶头穿孔时的工况条件十分恶劣,顶头需与高温的管坯无间隙地接触,同时还要受到来自管坯的摩擦力和挤压力,因此造成顶头顶部在穿孔过程中极易发生磨损、坍塌变形等现象,从而大大缩短了顶头的使用寿命。
实用新型内容:
本实用新型要解决的技术问题是,提供一种耐高温、耐磨、不易变形、可大大提高使用寿命的顶头。
本实用新型的技术解决方案是,提供一种具有以下结构的顶头:它包括顶头本体;所述的顶头本体顶部设有复合高温合金头。
采用以上结构后,与现有技术相比,本实用新型具有以下优点:由于本实用新型在顶头本体的顶部设有复合高温合金头,我们知道,复合高温合金头具有很好的耐磨性和耐高温特性,因此,本实用新型在穿孔过程中其顶部会在复合高温合金头的作用下不易发生磨损、坍塌变形等现象,从而大大提高了本实用新型的使用寿命。
附图说明:
图1是本实用新型顶头的主视结构示意图。
图2是本实用新型顶头的结构示意图。
图中所示,1、复合高温合金头,2、顶头本体,3、内腔。
具体实施方式:
下面结合附图和具体实施方式对本实用新型作进一步说明:
如图1和图2所示,在本具体实施方式中,本实用新型顶头包括顶头本体2;所述顶头本体2顶部设有复合高温合金头1;所述顶头本体2上设有内腔3;所述内腔3上设有螺纹。
