Latest Patents

Ooka holds a patent for a method of forming spring washer blind-holes into a piston for an automobile transmission. The problem this invention addresses is the eccentric load on a pin and the deformation and cavity issues that arise during the extrusion process. By flattening an annular region along the peripheral edge of the end plate of a secondary workpiece, Ooka's method allows for the effective formation of spring washer blind-holes. The process involves pressing the lower die with upper dies while applying cushion pressure, enabling the pins to perform an extrusion operation from the backside of the end plate. This innovative technique ensures that the extruded material flows into the recess holes of the upper die, resulting in the successful formation of the blind-holes.
