초록 ▼

Apparatus for forming a reinforced pressure resistant can end shell from sheet material comprises a cutting ring (11), a cutting punch shell (13) enterable into the ring (11) to blank out a disc of material therebetween, an annular draw ring (14) axially aligned with the cutting punch shell (13) to support a peripheral margin of the disc held against it by the cutting punch shell, a die center ring (15) arranged coaxially and slidably within the draw ring (14) and having an end face profiled to define a surface of a seaming panel of the can end shell, an ejector pressure ring (19) arranged coaxially and slidably within the punch shell and axially aligned with the die center ring so that when in use peripheral material of the blank is restrained between the die center ring and the ejector pressure ring, a draw punch center (16) arranged coaxially and slidably within the ejector pressure ring and reform pad (20) arranged coaxially and slidably within the die center ring to engage the central panel of the blank opposite the draw punch center. The end profile of the punch center comprises an annular radiused nose (22) surrounding and defining a central substantially frustoconical recess (23), and the reform pad comprises a central cylindrical portion, dimensioned to deform the central portion of the blank around the nose (22) of the punch center and into the recess (23), and an outer ring (31) spaced from the central cylindrical portion by an annular recess (30) dimensioned to receive the nose of the punch center; the outer ring having an inward facing frusto-conical face (311) which flares outwardly from the recess (30).

대표청구항 ▼

A method of forming a reinforced pressure-resistant can end shell comprising the steps of providing a substantially planar metallic blank having a central portion and a peripheral portion, deforming the blank in a first deformation stage to cause movement apart of the central and peripheral portions to offset said portions out of a common plane, thus drawing the blank into a generally flanged cup-shaped configuration defined by the central portion, a generally U-shaped channel extending about the central portion, a frustoconical wall and an annular seaming panel, and, in a second deformation stage, causing movement towards one another of the central portion and annular seaming panel to deform at least a part of the metal of the frusto-conical wall into the U-shaped channel to form an anti-peaking bead of the can end shell; and, during the second stage and simultaneously therewith, pushing the frusto-conical wall progressively radially inwardly toward the central portion. A can end comprising a peripheral seaming panel (25), a frusto-conical chuck wall (26) depending from the inner periphery of the peripheral seaming panel, a generally U-shaped anti-peaking bead extending radially inward from the frusto-conical chuck wall, an annular wall extending upwardly in an axial direction from the inner periphery of the anti-peaking bead, a generally flat central panel supported within the frusto-conical chuck wall by said annular wall, characterized in that the anti-peaking bead comprises a first annular portion (35) of arcuate cross section extending outward from the annular wall (34), a second annular portion (36) of arcuate cross section extending inward from the substantially frusto-conical chuck wall (26), an annular connecting portion (38) joining said first annular portion (35) to said second annular portion (36), the radius of curvature R of the first annular portion (35) being less than the radius of curvature r of the second annular portion (36), said radius r being in a range between 0.18 mm and 0.43 mm, and the frusto-conical chuck wall (26) includes a kink (42) joining the second annular portion (36) to the frusto-conical chuck wall (26) at a level between the central panel and the connecting portion (38) and most immediately adjacent the connecting portion (38).
