成形装置。[Scope of Claim for Utility Model Registration] (1) An upper die set is provided with an upper die set, a lower die set is provided with a lower die set, an upper punch connected to a press device is slidably provided on the upper die set, and the lower die set is provided with an upper punch connected to a press device. is provided with a slidable lower punch that is raised and lowered by the operation of the main cylinder, and the lower die set is further provided with a sub-cylinder that is activated by the lowering of the upper die set, and a side cylinder that moves the side punch back and forth from the side between the molds. In the forging forming apparatus, a hydraulic chamber compressed during forming the sub-cylinder and a hydraulic chamber to which oil is supplied during forming the main cylinder and side cylinder are in communication, and the hydraulic chamber of the sub-cylinder and the side cylinder are in communication with each other. The oil passage that communicates with the hydraulic chamber of A forging forming device characterized by being equipped with a valve that allows oil to return. (2) Claim 1 of the utility model registration characterized in that the switching of the valve to the side that only allows oil flow from the sub-cylinder to the side cylinder is delayed from the time when pressure release is completed. Forging forming equipment.
