A transfer press machine which can accurately and promptly check interference and can be easily handled is provided. The transfer press machine includes an interference check device including: a data-conversion constituent element storage section which stores a press-side data-conversion constituent element and a transfer-side data-conversion constituent element in a state of being placed in virtual space to have the same relative positional relationship as in real space; a virtual press operation control section which causes the press-side data-conversion constituent element to perform a virtual press operation in the virtual space according to a press motion; a virtual transfer operation control section which causes the transfer-side data-conversion constituent element to perform a virtual transfer operation in the virtual space according to a transfer motion; a virtual synchronization timing information generation-output section which generates and outputs virtual synchronization timing information, and a virtual interference determination section which determines whether or not interference occurs between the press-side data-conversion constituent element and the transfer-side data-conversion constituent element during a transfer press cycle.

Transfer press machine

A plurality of closing cylinder devices are provided between a bolster of a press machine and a bed containing a lower mold of a hydroforming device. An upper mold is attached to a slide of the press machine. The upper mold and lower mold come together to form a cavity having the shape of the exterior of the desired molded product. A closing block, being movable between a first position which is between the slide and a crown of the press machine, and a second position, which avoids the slide, permitting free movement of the slide from the crown to the lower mold. When a material to be hydroformed is place in the lower mold, the upper mold is lowered. The closing block is fit into its first position, thereby restricting movement of the slide in the vertical direction. A inner work pressure is provided by a fluid inside the material to be molded. The closing cylinder devices provide a pressure, based upon the inner work pressure, to maintain the cavity at the desired shape, preventing the upper mold and the lower mold from being separated by the inner work pressure.

Hydroforming method and hydroforming device

A high precision, all-purpose, double action hydraulic press, which can control the speed, position, and parallelism of each slide, can conduct mold exchanges easily, and prevent the breakthrough phenomenon is provided with an outer slide , an inner slide , drive cylinders and which drive each of the slides, position detection devices and which detect the position of each of the slides, push pins , a damper cylinder which prevents breakthrough phenomenon, and a die plate which is equipped with push pins . By controlling the flow in the hydraulic pressure circuit which is connected to each of the drive cylinders, the speed, position, and parallelism of each of the slides are controlled.

Double action hydraulic press

A hydraulic press has closed loop feedback control on a slide, a slide pad and bolster cylinders. Hydraulic cylinders actuating various components of the press are controlled according to ideal position estimates to produce consistent and precise pressing action. A closed loop control consists of an ideal position/pressure value generator, a position/pressure detector and an arithmetic unit comparing the ideal and actual position/pressure values. Using the ideal and actual comparison result, the arithmetic unit produces a control signal to drive a cylinder to a desired position/pressure. The hydraulic press is capable of performing several operations on a workpiece in one press cycle, an improvement over presses requiring several operation steps or die changes. The bolster cylinders augment clamping force, reduce shock, and improve die alignment to produce better results with less wear on press components.
