の過負荷安全装置。[Claims for Utility Model Registration] (1) It has a linear driving force transmission path, one end of which is connected to the rotating shaft inside the crown via a motion conversion mechanism, and the other end of which is connected to the feed bar side, A feed bar drive mechanism in a transfer press machine that drives the feed bar by converting rotation into linear reciprocating motion in the drive force transmission path by the motion conversion mechanism, and a cylinder in the drive force transmission path, and a cylinder movable to the cylinder. a piston rod with a piston of
A transfer system characterized in that the cylinder and piston rod are integrally moved in a linear reciprocating manner by the hydraulic pressure in the cylinder acting on the piston, and the cylinder and the piston rod are moved relative to each other by the action of an overload exceeding the hydraulic pressure. Overload safety device for feed bar drive mechanism in press machines. (2) In paragraph 1 of the claims for utility model registration,
There is one cylinder, two pistons and two piston rods, one piston rod is connected to the rotating shaft side via the motion conversion mechanism, the other piston rod is connected to the feed bar side, and both pistons are connected to each other through the motion conversion mechanism. Due to the pressure applied to the cylinder by the hydraulic pressure, both piston rods reciprocate in a straight line as one, and
An overload safety device for a feed bar drive mechanism in a transfer press machine, characterized in that relative movement occurs in both piston rods due to the action of an overload exceeding the hydraulic pressure.
