Title: Press machine
Inventor: SHIMOKATA TOMOHISA
IPC: B30B1/26
Filed: 2019-03-29
Abstract: To provide a press machine, whose operation speed can be increased more than before.SOLUTION: A press machine 10 according to the present invention comprises upward-movement restricting member 25 that receives power of a driving source (a motor 70) through a power transmission path not via a ram 12 to move up and down relatively to a sleeve 50 for molding. The upward-movement restricting member 25 restricts a shaft 26 for molding from moving up when the sleeve 50 for molding moves up together with the ram 12, which can surely separate the sleeve 50 for molding from a work-piece 90. This can surely prevent occurrence of a situation that the sleeve 50 for molding, the work-piece 90 and the shaft 26 for molding move up integrally together with the ram 12, which enables operation speed of the press machine 10 to be increased.SELECTED DRAWING: Figure 2
