A press forming system includes a press working unit, a material supply device, a detection device, and a control device. The press working unit includes a slide that moves in accordance with an operation pattern in which the slide passes through an advance position where press forming is formed from a withdrawal position, and returns to the withdrawal position. The material supply device starts a supply operation at a synchronous timing before the slide returns from the advance position to the withdrawal position. The control device performs a control for stopping the slide before the slide reaches the withdrawal position from the advance position in a case where the suppliable state of the forming material is not detected within a predetermined determination period by the detection device.

A stacking system for aligning and stacking stamped sheet metal parts is provided. The stacking system includes a frame configured to coordinate a plurality of sub-systems including a parts catcher, receiving head including a plurality of alignment cylinders, and a set of elevating tables on a shuttle platform. Parts are received by the catcher from a conveyor belt and transported to a receiving head for alignment to a targeted position. After the formed part is aligned to the stack, the lift table is lowered such that space is available for another part to be aligned. After a predetermined number of formed parts has been stacked, a table shuttle will slide the lift table to an unloading position accessible by a fork truck.

A workpiece transport unit including a pair of arms, an opening/closing mechanism configured to open and close the pair of arms in a horizontal direction, a pair of first placement surfaces provided at the pair of arms and configured for a first workpiece to be placed thereon, and a pair of second placement surfaces provided at the pair of arms and configured for a second workpiece to be placed thereon.

A duct making apparatus includes a first station configured to accept a formable sheet material and a second station configured to receive the formable sheet material from the first station. The first station includes a mechanism for forming one of a male lock bend and a female lock seam in a leading edge of the formable sheet material. The second station includes a retractable conveyor. Movement of the sheet material from the first station to the second station defines an axis of travel of the sheet material. The retractable conveyor is selectively movable from a first position in which the retractable conveyor is in close association with the first station, and a second position in which the retractable conveyor is spaced from the first station.

It is configured such that, for performing variable engravement for each formed object on a coil material to be fed to a press machine for molding a part of a can, a formed object with an engravement can be molded at a high productivity. A laser engraving device is a device for performing laser engraving on a coil material to be fed to a press machine for molding a part of a can, and includes a feeding mechanism for deeding a coil material at a predetermined speed, a laser head for irradiating the coil material fed at the predetermined speed with a laser beam, and performing engravement for each formed object, and a data communication unit for switching engraving data of the laser head. The data communication unit collectively switches a plurality of engraving data to be subjected to engravement on a plurality of formed objects, and the laser head continuously performs engravement of the plurality of engraving data on predetermined positions of the coil material.

Provided are a method and apparatus for manufacturing hot press formed parts for a multi-step process, the method comprising: a heating step for heating a strip material; a transferring step for transferring the heated strip material to a processing apparatus having mounted on a press a plurality of molds comprising a notching mold and/or a blanking mold, a forming mold, and a trimming mold; a notching step, for obtaining a notched material connected to the strip by means of a web portion by cutting a part of the material by means of the notching mold, and/or a blanking step for obtaining a blanked material separated from the strip by cutting a part of the material by means of the blanking mold; a forming step of transferring and positioning the material which has gone through the notching step and/or the blanking step near the forming mold, and then forming the material by means of the forming mold; and a trimming step for removing, by means of the trimming mold, an outer edge portion of the material which is unnecessary for a final product shape.
