Description
Cross reference to related applications
This application claims the equity of the U.S. Patent application for the Serial No. 15/382,850 submitted on December 19th, 2016,
Its is incorporated herein by reference.
Technical field
Disclosed design relates generally to container, more particularly, to canister, such as beer or beverage can and food
Product tank.Disclosed design further relates to cup and the blank for forming cup and container.Disclosed design is further related to for selecting
Property forming cup or container bottom part to reduce the method and machining tool of the amount of the material in cup or bottom part.
Background technique
It is well known that drawing and ironing metal slabs to be to manufacture thin-walled pressure vessel or tank body, to be used for packaged beverage (example
Such as soda；Noncarbonated beverage products), food or other substances.As is known, many such containers have general cylindrical shape
Shape and the example that is discussed herein of hypothesis there is this shape.It should be understood, however, that disclosed container (and
Cup as container) and method for shaping this container/cup be not limited to this specific shape.
Shape the initial step of this container first is that forming cup.As shown in Figure 1, cup is initially to cut down from sheet material
General plane blank 1.Then blank 1 is drawn into cup 2.Cup 2 is usually more shorter than finished container and wider.Therefore, cup 2 one
As be subjected to that cup is further configured to the various extra process of finished container.Cup includes base portion 3, has the side wall 4 to dangle upwards.
Container body (hereinafter referred to as tank body 5 (Fig. 2)) by extra process shape, the extra process be such as, but not limited to drawing,
Again drawing and ironing cup 1.Tank body 5 further includes base portion 6 and side wall 7.Tank body base portion 6 includes bottom profile.That is,
As used herein, " bottom profile " be forming after base portion 3,6 shapes.In general, Used for Making Beverage Container Body 5A, bottom profile are from annular
Ridge 8 slopes inwardly, to shape inwardly projecting approximately hemispheric protuberance 9.On the contrary, food tank body 5B (forms the phase in Fig. 4 E
Between show) with general planar bottom profile.During forming cup 2 and/or tank body 5, protuberance 9 is by " protuberance device " forming.Structure
Equipment and machining tool with forming cup 2 and/or tank body 5 are made in the U.S. Patent application of Serial No. No.15/286,954
It shows, is incorporated herein by reference.
Industrially wish always to reduce specification, to reduce the quantity of material for shaping this container.However, with by relatively thin
It is that there are the tendencies of fold for container that gauge material, which forms the relevant other shortcomings of container, is especially stretching and is swelling the phase again
Between.The proposal of the prior art largely concentrates on shaping bottom profile of various shapes, these bottom profiles are intended to
It is firm and therefore can resist buckling, while the metal with relatively thin base specification being made to can be used in manufacturing tank body.Such as
Used herein, " base specification " refers to the original depth of material and is not limited to base segments/element thickness.Therefore, it passes
The hope of system is to maintain the material thickness in protuberance and bottom profile, to keep or increase the intensity of tank body in this region, from
And it avoids wrinkling.
Machining tool for shaping protuberance cup or tank body generally includes bending or bowed formed punch core and has corresponding bent
The mold core of rate, so that the tank body of protuberance is by the material (such as, but not limited to, metal slabs) that conveys between formed punch core and mold core
It is formed.In general, formed punch core extends downwardly into mold core, to shape the cup or tank body of protuberance.During the shaping operation, material
It is drawn between formed punch core and mold core.That is, the thickness in order to keep bump, any in part to be swelled
Material is slightly clamped on side relatively.Therefore, material direction can swell mobile (for example, sliding) or flowing in forming, with
Desired thickness is kept in bottom profile.In addition, such as United States Patent (USP) No.5, shown in 394,727, it is known that forming includes big
Cause plane (when observing in cross-section) surface rather than the bottom profile of protuberance.Also by mold drawable material come at
This protrusion of shape.The protuberance and protrusion of known technology are configured to generally remain the thickness of material during forming protuberance.
In addition, by have substantially hemispherical protuberance cupuliform at tank body have also the drawback that.For example, certain Used for Making Beverage Container Bodies are logical
Crossing makes the protuberance on cup invert or flatten and shapes protuberance again on tank body and formed.It is shown at this in Fig. 3 A ﹣ 3C
The arrangement of reason and the step include reversion protuberance (Fig. 3 B and 3C) and forming tank body swells (Fig. 3 D and 3E) again.It is worth noting
, as shown, the cross section of the generally arcuate protuberance (that is, approximately hemispheric protuberance) of cup is usually arc, define
The volume of metal.When cup is configured to tank body, it is necessary to re-form the volume of the metal.It is moreover observed that generally arcuate
Protuberance include relative to other shapes (the butt protuberance shown in fig. 5 such as, but not limited to as discussed below) more
Big metal volume.This bigger metal volume allows metal to wrinkle during forming tank body or with other defect.For
It is also in this way, food tank body usually has when food tank body is shaped by the cup with generally arcuate protuberance for food tank body
The bottom of general plane.That is, the step of forming food tank body, is as shown in Fig. 4 A ﹣ 4E.As Used for Making Beverage Container Body, when in cross
The bigger metal volume that substantially hemispherical is swelled in (that is, generally arcuate protuberance) when observing in section shaping again
Defect is formed in food tank body when cup.
Therefore, in the container of such as beer/beverage can and food cans etc, and in the cup and offer selectively shaped
In the machining tool and method of this cup and container, there are improved spaces.That is, problem of the existing technology is
Cup or tank body use too many material, and too many material is used especially in base portion.
