Description

Plug for processing seamless steel tube

Technical Field

The utility model relates to the technical field of plugs, in particular to a plug for processing a seamless steel tube.

Background

The molybdenum plug is made of molybdenum-titanium-zirconium-carbon alloy and is used for producing a seamless steel pipe threading machine core rod plug. The alloy is used for perforating seamless steel pipes, such as stainless steel, drill steel, high-temperature alloy steel, molybdenum and other special parts. The most prominent feature of seamless steel pipe production is the use of internal deformation tools such as plugs, mandrels, which not only participate in the deformation but are also the most important factors in determining the primary processes of steel pipe production such as piercing, pipe rolling, and proper, efficient and economical operation.

The existing plug presses the material inside the steel pipe through the pressure generated by the center in the machining process through the inside of the steel pipe. The tip bears most of the pressure, and the tip is damaged faster than the tip body in the long-term use process through the change of internal stress. The existing plug is more material-consuming, and the damaged part cannot be replaced according to the need, so that the cost is increased; the existing thimble is easy to damage the inner wall of the steel pipe during taking out because the outer part of the steel pipe is not shaped successfully, and the later use is inconvenient.

For this purpose, a plug for processing seamless steel pipes is proposed.
