Abstract

一种三辊轧机,本实用新型在于提供一种热轧钢管的设备。其特征在于有三个锥形轧辊和一顶头组成一个锥形环孔形。能代替冷拨方法生产钢管,提高钢管生产效率。

Description

三辊轧机
本实用新型涉及一种大变形量的轧管机。
目前生产无缝钢管的一般方法是采用冷拨的方法,其生产效率很低。为提高钢管的生产效率,本实用新型提供一种采用热轧的三辊轧机。
本实用新型实现的主要原理是采用3个锥型辊,和一个顶头组成一个锥型环孔型。钢管从大端孔型进入,由小端孔型轧出去,达到减径目的。另由顶头存在达到减壁目的。下面结合附图说明本实用新型的实现方法。图1是本实用新型的主机外型图图2是本实用新型的主机正面示意图图3中本实用新型的主机传动示意图
本实用新型是由3组锥型轧辊辊座(1)、一个机架(2)等组成其传动是通过电动机带动皮带轮(9),皮带轮(9)带动空心齿轮(8),空心齿轮(8)带动三个齿轮(7),齿轮(7)分别带动3个伞齿轮(6),伞齿轮(6)分别带动伞齿轮(5),伞齿轮(5)带动锥型辊,3个锥型辊(4),锥型辊和顶头(11)组成一个锥型环孔型轧制钢管。
本实用新型在附图2中所示的调整螺丝(3),是调整3组锥型辊的相对位置达到调整孔型的目的。
本实用新型的结构简单,调整方便,在实际使用中能提高钢管生产数率。

Claims (3)

1、一种三辊轧机,它由三组锥形辊座和一个机架等组成,其特征在于在机架上装有三组锥形辊座。
2、根据权利要求1所述的三辊轧机,其特征在于轧辊是锥形的。
3、根据权利要求1所述的三辊轧机,其特征在于三个锥形轧辊和一个顶头组成一个锥形环孔形。
