Problems solved by technology

However, the elongated body shape, narrow neck shape, and threaded or crowned opening of metal bottles require increased deformation of the original aluminum cup during deep drawing and thinning and compared to two-piece aluminum can fabrication , leading to increased manufacturing defects and higher reject rates

Embodiment Construction

[0032] figure 1 is an exploded view of the main body manufacturing machine 100, the main body manufacturing machine 100 includes a punch 108 and a punch assembly 110, a yoke slider 112, a main bulkhead 114, a secondary bulkhead 116, a redraw assembly 118, and a redraw die 102 , a first thinning die 104 , a second thinning die 106 , a dome die 120 and a stripping assembly 122 . As will be discussed in more detail below, the body making machine 100 has a stroke length of about 30 inches, and when combined with figure 2 When used, the toolkit 200 can be used to form a cup having a height-to-diameter ratio of about 4 and an overall height of about 9.4 inches, which is then used to form a bottle-shaped container having a height-to-diameter ratio of about 4.

[0033] As described above, the longest stroke length currently available in commercial high speed body making machines is about 30 inches. Conventional tool designs in 30 inch length body making machines were found to be in...

Abstract

A tool pack (200) is described that includes a redraw die (102), a first ironing die (104) and a second ironing die (106). The tool pack (200) may be incorporated in a bodymaker (100) that has about a thirty-inch stroke to form a metal cup with a height to diameter ratio of about four. In some embodiments, the redraw die (102), the first ironing die (104) and the second ironing die (106) are situated in the body maker (100) so that each reduces a sidewall thickness of the cup that is forced through the redraw die (102), the first ironing die (104) and the second ironing die (106) by a plunger by a predetermined amount to produce a cup that can be formed into a bottle-shaped container with low defect rates.

Description

technical field [0001] The present disclosure relates to a kit for making metal containers, and in particular to a kit including a redraw die and two thinning dies for consistently forming high aluminum cups at high production speeds for bottle production describe the container. Background technique [0002] Thin-walled two-piece metal cans are often produced using deep drawing and thinning processes. In the drawing and thinning process, a flat circular metal blank is drawn through one or more drawing dies to form a shallow preform cup. The preform cup is then mounted onto the free end of the punch extending from the reciprocating ram. The pre-formed cup is then "thinned" through one or more redraw dies and then one or more thinning dies to lengthen and thin the sidewalls of the cup to form the already formed cup. The term "ironing" refers to the operation of passing a cup with a punch through a thinning die to cause the sidewall thickness of the cup to decrease and elong...
