  • Patent number: 11358203
    Abstract: A method for producing a press-formed product includes a first pressing step and a second pressing step. In the first pressing step, an intermediate formed product is formed from a processed material by using first press tooling. The intermediate formed product includes a stepped section of a top plate section, a temporary vertical wall section adjacent to the top plate section via a ridge section and having at least part of the shape of the vertical wall section, and a temporary flange section adjacent to the temporary vertical wall section via a temporary ridge section. In the second pressing step, the press-formed product is formed from the intermediate formed product. In the second pressing step, forming is performed such that the temporary ridge section is moved toward the temporary flange section with at least part of the top plate section of the intermediate formed product restricted.

In a stamping device, the timing at which an upper pad moves downward and grips a work piece between the upper pad and a first supporting surface is adjusted so as not to be later than the timing at which an upper bending steel makes contact with the work piece. The height of a lower end of the upper bending steel after the timing at which the upper bending steel has made contact with the work piece, and the height of a lower surface of a drawing pad after the timing at which the work piece has been gripped between the drawing pad and a third supporting surface are adjusted such that the lower end of the upper bending steel and the lower surface of the drawing pad move downward while maintaining the same height at a boundary between the upper bending steel and the drawing pad.

  • Publication number: 20100269562
    Abstract: A forging press has a workpiece manipulator having a shaft centered on and rotatable about an axis, a grab for holding the workpiece in the press and rotationally fixed to the shaft carrying the grab and centered on and rotatable about an axis, and a disk fixed angularly to the shaft and projecting radially outward therefrom. Two couplings are juxtaposed with the disk, rotatable relative to the shaft about, and have respective clutches for locking onto the disk so that when locked onto the disk the couplings are rotationally fixed to the disk. Respective actuators connected to the actuators can angularly shift the disk and thereby rotate the shaft, the grab, and the workpiece held by the grab.

  • Patent number: 7788805
    Abstract: The present invention provides a rocker arm manufacturing method capable of improving the durability and excellent in productivity. In the method according to the present invention, an intermediate product 13 having both side walls 20 extended in a predetermined direction and arranged in parallel with each other and one end side connection wall 30 connecting lower ends of a longitudinal one end of both the side walls is obtained. Next, both side walls 20 formed at the one end of the intermediate product 13 are inwardly bent. Thereafter, ironing dies 60 are pressed down against outer surfaces of both the inclined side walls 20 from an upper side to a lower side to execute ironing of outer surface portions of both the side walls 20 to downwardly plastically fluidize the constituent material of both the side walls 20 to thereby form valve stem guide walls 35 at both sides of the one end side connection wall 30 in a downwardly protruded manner.

  • Patent number: 7584641
    Abstract: A forging machine includes a support having two sidewalls, and two track plates attached respectively to the sidewalls. A slide body of a die assembly is mounted slidably inside the support between the sidewalls. Two first rolling devices are respectively mounted on the track plates near the front of the support to contact the slide body. Two second rolling devices are mounted respectively on the sidewalls above the track plates and near the rear of the support to contact the slide body. Due to the first and second rolling devices contacting the slide body near the front and rear of the support, the slide body can slide stably in the support without positional deviation.
