Description

Technical Field

[0001] The utility model relates to the field of seamless steel pipe processing, in particular to a perforating device for processing seamless steel pipes. Background Art

[0002] Seamless steel pipe perforation is an important process in the production of seamless steel pipes, and the tool used is a seamless steel pipe perforator to perforate the middle of the seamless steel pipe. The patent office database search revealed a perforation device for processing seamless steel pipes with the publication number CN218855668U. The perforation vehicle body will drive the mandrel to move during the movement, and the mandrel can be driven to rotate in the sleeve through the rotating mechanism. The self-rotation of the mandrel can make it easier to insert into the solid steel pipe to be perforated. The solid steel pipe heated to a high temperature and softened can be perforated by moving the mandrel forward. After the mandrel completely passes through the solid steel pipe, the perforation vehicle body is moved backward through the driving mechanism. Under the action of friction, the solid steel pipe can be dragged out. However, after the mandrel continuously rotates and perforates the high-temperature seamless steel pipe, the mandrel is damaged quickly by friction, and the temperature of the mandrel itself is also very high, which makes it inconvenient to replace the mandrel.

[0003] Therefore, it is necessary to invent a perforation device for processing seamless steel pipes. Utility Model Content
