Dual forging system and method
An apparatus includes an anvil having a first end and second end, and a press head reciprocally mounted relative to the anvil. The apparatus further includes an induction heater having a workpiece discharge end mounted adjacent the first end of the anvil, and a plurality of first station dies secured to the anvil. The first station dies each form at least a portion of a first contour. A plurality of second station dies are also secured to the anvil, the second station dies each defining at least a portion of a second contour.
METHOD AND APPARATUS FOR PROGRESSIVELY FORGING A MOBILE DEVICE CASING
A method and apparatus for progressively forging a mobile device casing is described. The method may include advancing an initial mobile device casing cut from an extruded sheet through a plurality of stations of a transfer die assembly. The method may also include performing a sequence of forgings on the initial mobile device casing to progressively form a mobile device casing having at least one three dimensional feature formed within at least one cavity of the progressively formed mobile device casing.
Mold fixing structure
The present invention provides a mold fixing structure capable of easily performing work in which a mold carried into a machine is fixed to a mold mounting surface of the machine, and work in which the mold fixed to the mold mounting surface is carried out to the outside of the machine.
Pressing method of a flexible printed circuit board and a substrate
A pressing method operatively associated with a press apparatus includes: providing a first substrate connected with a flexible printed circuit board onto a stage; providing a second substrate onto the stage; arranging the flexible printed circuit board on the second substrate; pressing a pad electrode-free area of the flexible printed circuit board; and pressing first pad electrodes of the flexible printed circuit board and second pad electrodes of the second substrate.
FORGING DEVICE
A forging device produces a forged product in which a protrusion is formed on a base plate. The forging device has a die with a molding hole and a punch to be driven into the molding hole. A protrusion molding cavity is formed in a bottom surface of the molding hole or a tip end surface of the punch in the die. A base plate molding portion is formed between the tip end surface of the punch and the bottom surface of the molding hole. A burr molding portion is formed between the tip end portion outer peripheral side surface of the punch and the inner peripheral side surface of the molding hole. The inner peripheral side surface of the molding hole is formed by an inclined surface that approaches an axis as it advances toward the pressing direction of the punch.
Point forming processes
A progressive forming machine with die and tool units, one of said units sliding a limited distance along its axis and biased by a spring force towards the other unit, the units each having an end face with a smooth surface finish adapted to press against the smooth surface finish of the end face of the other unit, the end face area of one of the units being relatively small compared to its major cross-sectional area whereby a high contact pressure between the end faces is obtained for a given spring bias force such that extrusion/cooling oil coating a workpiece received in cavity portions is restrained from leakage from the cavity portions across said end faces during a hydrostatic trapped extrusion shaping the workpiece to a degree beyond limits of conventional cold-forming processes.
FORGING DEVICE AND RE-CENTERING ATTACHMENT OF FORGING DEVICE
Disclosed is a forging device containing a die insert 1, a stationary die case 2, a movable part (Ram) 3, a punch holder 4, and a punch tool 5. The punch holder 4 contains upper and lower reference stud holes 14,15, upper and lower reference studs 7,8 loosely fitted in the respective holes 14,15 in the movable part 3, an alignment adjusting bolt 17T, etc. to be tightened into a direction of the stud 7 to move the punch holder 4 in an alignment direction, and clamping nuts 9 engaged with the respective studs 7,8, to fix the punch holder 4. A positioning nut 22T is received by a male screw portion 21 of at least one alignment transcription bolt 20T and fixed thereto, and the nut 22 is brought into contact with the punch holder 4 at a complete alignment position, whereby the bolt 20T and the punch tool 5 should be attached/detached as a pair.
Sideways forming
A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations evenly spaced across the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the tooling cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the mechanism including a cam and a cam follower radially outward of imaginary outward projections of the associated tooling cases, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the mechanism including a tool for forming the blank by applying a sideways force on the blank.
MANUFACTURING METHOD OF PRESS-MOLDED ARTICLE AND PRESS MOLDING APPARATUS
A manufacturing method of press-molded article of the present invention comprises a step of placing a member to be pressed in a press molding apparatus and a step of pressing a flat plate portion of the member to be pressed by bringing a first press portion and a second press portion closer to each other. A first opposing surface and a second opposing surface, while facing to each other, keep in contact with the flat plate portion during pressing. In the press step, a thick part is formed on the flat plate portion by allowing a part of a material of the flat plate portion to flow, in a press direction, into a thickened portion-forming section formed on the first opposing surface. The second opposing surface is moved to the press direction as the flat plate portion is pressed by the first press portion and the second press portion.
PRESS APPARATUS AND PRESSING METHOD THEREOF
A press apparatus includes: a stage to support a first substrate and a second substrate of a display device; a fixing member to fix a flexible printed circuit board connected with the first substrate onto the second substrate; and a press member to press first pad electrodes of the flexible printed circuit board and second pad electrodes of the second substrate, and the fixing member is configured to press a pad electrode-free area of the flexible printed circuit board. A pressing method of a press apparatus is also provided.
