DIE-PRESSING PUNCH CAPABLE OF ADJUSTING INITIAL LOAD OF COIL SPRING IN ACCORDANCE WITH MATERIAL OF WORKPIECE, DIE-PRESSING DIE SET, AND BEVELING METHOD
20190168276 · 2019-06-06 · ·

A die-pressing punch used for die-pressing a workpiece includes a punch guide, a punch body that is provided vertically movably and non-rotatable about its axial center with respect to the punch guide, a punch head screw-fitted with the punch head. The die-pressing punch further includes a roller unit that is provided inside the punch guide beneath the punch body vertically movably and has a rotatable roller protruding downward from a bottom face of the punch guide, and an urging member that is provided between the punch body and the roller unit and urges the roller unit downward. The die-pressing punch further includes a joint member that is jointed with the punch head non-rotatably about the axial center, and an operable member. The operable member switches. joint member between a rotatable state and a non-rotatable state about the axial center with revect to the punch guide.

DIE-PRESSING DIE HAVING DUST COLLECTION PASSAGE AT PERIPHERAL EDGE PORTION OF ROLLER UNIT
20190160508 · 2019-05-30 · ·

A die-pressing die used for die-pressing a workpiece includes a die body on whose upper face a die hole is formed and on whose bottom face a discharge hole for discharging dusts of the workpiece is formed, and a roller unit disposed within the die hole and having a roller protruding upward from the upper face of the die body. A collection passage for collecting the dusts is formed at a peripheral edge portion of the die hole. One end of the collection passage is opened at the upper face of the die body, and another end thereof is opened to the discharge hole. The collection passage is configured to suction air due to a negative pressure state in the discharge hole.

ROTARY STAMPER
20190054514 · 2019-02-21 · ·

A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.
