[0002] With the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have increased day by day. Thick-walled welded pipes are one of the more common types. When welding thick-walled welded pipes, welded pipe extrusion dies are often required. However, there are still some defects in the actual use of such welded pipe extrusion dies for thick-walled welded pipes.

[0003] The welded pipe extrusion die used for welding thick-walled welded pipes can often only realize extrusion molding processing for the welded pipe in a single direction, and it is not easy to flexibly adjust the spacing of the extrusion die components according to the specifications of the welded pipe, which leads to low applicability of the device. Moreover, it often does not have a cooling protection structure for water circulation, which leads to sparks and losses caused by friction during the extrusion molding of the welded pipe products, which reduces the molding quality of the product and is difficult to promote. Based on this, we propose a new type of welded pipe extrusion die for thick-walled welded pipes. Utility Model Content
