The present invention relates to an abrasion test apparatus, and in particular, to an abrasion test apparatus for measuring an abrasion state due to repeated use of a mold used for molding heated metal.
In press working or forging processing of a heated metal material, the processing is performed such that a metal material to be processed is sandwiched between molds disposed at an upper part and at a lower part, a large pressurizing force is applied, and accordingly, the metal material is plastically deformed.
In the processing, since the mold directly comes into contact with the metal material, and due to the large pressurizing force, friction occurs repeatedly between the mold and the metal material.

FIG. 1 is a perspective view illustrating an outline of an abrasion test apparatus according to Example 1 of the present invention.
As illustrated in FIG. 1, an abrasion test apparatus 100 according to Example 1 of the present invention includes: a workpiece holding mechanism 110 for attaching and holding a workpiece W; a contact tool 120 repeatedly making contact and non-contact with the workpiece W; a rotating mechanism 130 holding the contact tool 120 to be freely rotatable; a data analysis mechanism 140 connected to the workpiece holding mechanism 110 through a connection line 142; and a heating mechanism 250 for heating the contact tool 120 during the test.
