本发明还涉及该一体式球型多通管件的制备方法。
一种一体式球型多通管件的制备方法,其包括如下步骤,
(1)、切割一圆形坯料,坯料的厚度为成品一体式球型多通管件的主管壁厚T的1.1~1.3倍;圆形坯料的的直径等于2L+3.14*SR+2H+10,其中L为成品一体式球型多通管件圆形直管筒体的直管长度,SR为半球形筒体的球半径,H为支管高度;
(2)、将切割好的圆形坯料放置于冲压模具上方,坯料中心与模具中心对齐;冲压模具,其包括模具座和冲头,模具座中设有一个冲压孔,冲压孔上部为圆柱形,冲压孔底部为半球形,在半球形的模具座中圆周均匀分布2~4个液压通孔,冲头的冲压段形状与模具座中的冲压孔形状相对应,在冲头中设有一液压胀形流通孔,在与冲头底部设有与液压通孔相对应的液压成形孔,液压成形孔与液压胀形流通孔相连通;
启动压机,通过冲头把圆形坯料挤压模具座的冲压孔中,形成一半成品;然后拔出冲头,在冲头上套入模具镶套;通过冲头继续挤半成品,同时在冲头的液压胀形流通孔内通入高压液体,通过液压成形孔对半成品的挤压和液压胀形,形成支管鼓包,由此制成球型多通管件半成品;镶套的外径和厚度与成品一体式球型多通管件圆形直管筒体的直径D及主管壁厚T相同,镶套的高度为支管高度H的1.5~2.5倍;
(3)、取出步骤(2)中制得的球型多通管件半成品,对支管鼓包进行切割从而形成支管,由此制得成品一体式球型多通管件。
本发明与现有技术相比所具有的优点为:本发明的一体式球型多通管件,采用圆滑过渡的整体化结构,摈弃了支管焊接方式,避免了焊缝应力集中,减少了泄漏环节,提高了多通管件的质量可靠性;本发明在半球形筒体上设置支管,可以将主管路的介质均匀地分配输送到多条支路管道,也可以将多条管道的介质均匀地集中输送到一条主管道。
