There is provided a conveying device that reliably discharges only scrap when simultaneously conveying the scrap and a pressed product without sacrificing cycle time. A conveying device for use in press forming includes: a conveying part that holds a product part and a scrap part of a workpiece after a cutting process, and conveys the product part and the scrap part to a next process; a nozzle part that is provided in the conveying part, and discharges compressed fluid toward the scrap part; and a controller that performs a control to release holding of the scrap part during conveyance of the workpiece and to blow compressed fluid toward the scrap part.

A workpiece manufacturing apparatus includes a punch, which is provided in a lower die assembly and punches out a workpiece from an unprocessed material, and an ejector, which is provided in an upper die assembly so as to be capable of approaching and moving away from the lower die assembly. The manufacturing apparatus further includes a spring, which is provided in the upper die assembly and urges the ejector toward the lower die assembly, and a locking device, which locks the ejector with respect to the upper die assembly at a position at which the punch punches out the workpiece and releases the ejector when the die assemblies are opened. The locking device includes an actuator, which is provided in the upper die assembly and slides a slider between a locking position, at which the ejector is locked, and a releasing position, at which the ejector is released.

A workpiece manufacturing apparatus includes a lower die assembly, an upper die assembly, a workpiece extracting device, and a workpiece conveying device. The lower die assembly includes a punch configured to punch out a workpiece into the upper die assembly. The upper die assembly includes an ejector configured to eject the punched out workpiece. The extracting device includes a catch plate configured to receive the ejected workpiece and a moving mechanism, which moves the catch plate between positions below the upper die assembly and the conveying device. The moving mechanism is configured to move the catch plate from the conveying device to the positions below the upper die assembly as the upper die assembly moves upward and to move the catch plate from the positions below the upper die assembly to the conveying device as the upper die assembly moves downward.

A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including but not limited to oil or lubricant adhesion.
