Description

Heat-resistant and wear-resistant plug with detachable cooling structure Technical Field The utility model relates to the technical field of plugs, in particular to a heat-resistant and wear-resistant plug with a detachable cooling structure. Background The piercing plug is an important tool for metal piercing process and mainly consists of a working section and a tail assembly section. The working section comprises a perforation cone section, a rolling cone section and an inverse cone section, and the shape of an inner hole of the working section is similar to that of an outer surface, so that a perforation plug with uniform wall thickness is formed. The design of the piercing plug has a significant impact on the stability of the piercing process and product quality. The working environment of the piercing plug is extremely severe, the service temperature is usually 23 ℃ between 900 ℃ and 1300 ℃, and the piercing plug is subjected to the combined action of axial pressure, radial stress and rotational friction, so that the surface hardness of the conventional plug is obviously reduced under the condition, and the plastic deformation is caused. Disclosure of utility model The utility model aims to provide a heat-resistant and wear-resistant plug with a detachable cooling structure, so as to solve the problems in the prior art.
