SLIDING FRICTIONAL FORCE GENERATION MECHANISM AND DIE CUSHION FOR PRESS MACHINE

摘要

A sliding frictional force generation mechanism includes a metal hole member 33 having a hole 36, a metal shaft member 31 fitted in the hole of the hole member in an axially slidable manner, and a lubrication mechanism 16 configured to supply lubricating oil serving as a cooling medium between the hole member 33 and the shaft member 31. The shaft member is fitted in the hole in an interference fit state. A die cushion device 10 for a press machine 11 including the sliding frictional force generation mechanism is also disclosed.
