Claims

[Scope of utility model registration request]

A feed bar equipped with a work clamping device is attached to a feed bar holding member, and this feed bar holding member is assembled to a slider that moves in the lateral direction so as to be movable up and down, and a rotating member equipped with a plurality of rollers is attached to the feed bar holding member via a crank mechanism. a cam member extending in the direction of movement of the slider, which connects the rotary members to enable crank operation of the crank mechanism by rotation of the rotary member, and prevents rotation of the rotary member by contact with the roller; ,
In a work conveyance device of a press mechanism in which the rotary member can be rotated by providing a circular portion for rolling a roller at the end of the cam member, the center of which coincides with the rotary member when the slider reaches its travel limit, One roller among the plurality of rollers is arranged at the center of the rotating member, and a groove is provided in which the roller is inserted into and engaged with a circular roller rolling portion of the cam member and extends to the center of the circular portion. A work conveyance device for a press machine, characterized in that another roller is caused to roll along the outer peripheral surface of a circular portion for roller rolling.
