Definitions
- the present invention relates to the bottom assembly to a container body and more particularly to an improved crimping process.
- the present invention relates to the manufacture of metal containers such as metal drums, barrels, cans and the like typically of cylindrical or polygonal section.
- this patent uses, during the setting of the seam, mandrels whose external wall is either vertical, or inclined towards the axis of the mandrel, or provided with an annular rim such that the part of the mandrel in direct contact with the bottom or the cover to be crimped is of a diameter greater than the part of the mandrel which is immediately adjacent to it.
- the funds or lids used are conventional funds or lids which have not undergone any particular preparation.
- Such a crimping process allows crimps not to take place under the effect of internal pressure, but the outside diameter of the crimping bead thus produced is not reduced.
- Reducing the diameter of the ends of a container body involves a separate step prior to crimping, with the additional costs involved.
- the bottom must have been reduced accordingly in order to adapt to the diameter of the ends of the container body.
- An object of the present invention is a method of crimping bottoms to a container body by which the final radial projection of the bead relative to the side wall of the container body is reduced during crimping.
- the invention thus provides a method of assembling a bottom to a container body by crimping to each other bottom flanges and container body, according to which a preformed bottom is produced having a central transverse portion. hollow, a skirt extending axially from this central portion, and a rim extending radially outward from this skirt, as well as a preformed container body having a side wall and a rim s' extending radially outwards from this side wall, the bottom is fitted on a mandrel in driving contact with the latter, the container body is engaged on the bottom in centering contact, their edges being in mutual contact , and a crimping tool is moved radially inwards so as to wind the edges into a crimping bead, characterized in that said bottom is worked out so that its skirt extends both axially and radially outward between the p central hollow recess and the rim, so that this skirt is radially spaced from the side wall of the mandrel tapering axial
- the initial space between the bottom skirt and the lateral wall of the mandrel makes it possible to reduce the diameter of the end of the container body and therefore the relative radial projection of the bead during crimping. Consequently, the cost of crimping is substantially that of a conventional operation of corresponding double or triple crimping. In fact, there may be reductions in ancillary costs, thanks to the reduced radial extension of the edges of the bottom and of the container body, since the length of sheets required is less than in the prior art because the bead of crimping is close to the axis of the container.
- a tapered zone is formed in the side wall of the container body substantially at the level of the central portion of the bottom.
- the bottom skirt widens from the hollow transverse central portion towards the edge and the drive contact is defined by the zones for connecting the preformed bottom and the mandrel.
- the flared skirt is preferably frustoconical (the half-angle at the top of it is largely responsible for the reduction of the radial projection of the final crimping bead) it may be only partially frustoconical or include an annular step at halfway in the axial direction.
- the mandrel has a transverse end wall and a lateral mandrel wall which tapers axially outwards from this end wall, the angle of tapering of this lateral mandrel wall relative to the axis of the mandrel being able to go up to 5 ° and preferably being about 3 °.
- a preformed stackable bottom adapted to be crimped to a container body, comprising a hollow transverse central portion, a skirt extending axially from this central portion, a zone concave annular connection connecting this central portion to this skirt, a rim extending radially outward from this skirt axially at a distance from this central portion, where said skirt extends both axially and radially from this central portion, and that a plurality of hollow stamps projecting inwards are formed in the concave connection zone and are adapted to come into contact with a corresponding connection zone of a crimping mandrel to drive the bottom in rotation with the mandrel, these stampings being further adapted to come into contact with the convex face of a connection zone of an identical underlying bottom in interlocking relationship with the latter so that the edges of this bottom and of the underlying bottom are axially spaced from one another in order to facilitate their separation and their handling.
- these stampings have
- the container body is in centering contact on the bottom skirt.
- the location of this contact zone varies according to the desired embodiment. In general, this does not require any modification of the configuration of the container body except as regards the radius of the connection zone between the side wall and the rim thereof.
- an annular or equivalent indentation may be formed in the side wall of the container body to form the centering contact area with the bottom.
- the diameter of the conventional rolling rods axially spaced along the container body is adopted to that of the bead. Consequently, in the case of barrels obtained by triple crimping in accordance with the invention, the diameter of the rolling rods is to be reduced correspondingly compared to that of the rods of conventional barrels obtained by triple crimping.
- the present invention is particularly suitable for triple crimping, in which case it is possible to reduce the radial projection of the bead below the diameter obtained by a conventional process.
- the invention also applies to double crimping, in which case the diameter of the bead can be reduced to the nominal diameter of the side wall of the container body.
- Figures 1 and 2 show the triple crimping of a sheet metal bottom 1 to a sheet metal container body 2 of a barrel in accordance with the process described in patent FR-E-89175 of December 9, 1965.
- the bottom 1 and the container body 2 are suitably preformed.
- the side wall of a container body 2 has a rim 3 extending radially outwards which is connected to it by an annular zone of connection with a large radius.
- the preformed bottom 1 has a hollow transverse central portion 5 connected by a concave annular connection area 6A to a generally cylindrical skirt 6 which is extended radially outwards by a flange 7 of a predetermined length for a triple crimping.
- the thickness of the container body 2 is denoted e and that of the bottom 1 is denoted e ', which in the following description will be considered as equal.
- the preformed bottom 1 is forcibly engaged on a rotary mandrel 8 which comprises an end wall 8A connected by a curved connection portion 8B to a cylindrical side wall 8C.
- the transverse central wall 5 of the bottom 1 bears against the end wall of the mandrel 8A and the skirt 6 of the bottom 1 is tightly engaged on the cylindrical side wall 8C of the mandrel 8.
- the side wall 8C of the mandrel 8 can be knurled in view of increasing the driving contact between it and the adjacent skirt 6.
- the annular connection zone 6A is normally out of contact with the annular connection portion 8B. The bottom 1 thus rests on the mandrel in the manner of a hat with an edge resting on a head.
- the container body 2 is received on the bottom 1, the edges 3 and 7 overlapping, the connection zone connecting the rim 3 to the container body 2 coming into centering contact with the skirt 6 of the bottom 9A, close of the junction of the side wall 8C with the curved connection portion 8B.
- the free edge 9B of the rim 3 of the container body carries against the bottom rim 7 in a circle offset inwards relative to the free edge of the rim 7 of the bottom.
- the crimping operation is carried out by displacement of the crimping tool or wheel 8 'radially inwards against the edges 7 and 3 of the bottom 1 and of the container body 2 while rotating the mandrel 8. Due to the configuration of the crimping tool or tools 8 ′ a bead of triple crimping of suitable conformation is obtained as shown in FIG. 2, the flanges 7 and 3 being wound against the external face 2A of the end of the body of container 2 and the bottom skirt 1 so as to define seven sheet thicknesses.
- the bead 4 elastically projects outwards relative to the lateral wall of the mandrel leaving an annular space in the form of a wedge between them (see FIG. 2), thereby increasing the actual diameter. of the resulting bead 4.
- the radial projection of this resulting bead 4 on the side wall of the container body is approximately 5 times the thickness e of sheet metal, that is to say 5 e as shown.
- the outside diameter of the resulting crimping bead is reduced during crimping.
- FIG. 3 In the first embodiment of the invention shown in Figure 3, we take a preformed container body 2 identical to that shown in Figure 1 and described above.
- the preformed bottom 11, for example in a press, is of a configuration different from that of the prior art.
- the bottom 11 has a hollow central transverse wall 15 connected by a concave curved annular zone of connection 16A to a frustoconical skirt 16 widening axially outwards, or downwards as shown, which is connected by an annular zone concave 16B to a flange 17 extending radially.
- the bottom 11 is received on the mandrel 18 substantially as in the prior art.
- the lateral wall of the mandrel 18C widens axially outwards, or downwards as shown, at an angle a with respect to the vertical axis of the mandrel (not shown).
- the side wall 16, as opposed to the illustrated prior art which provided a driving contact between the bottom and the mandrel, is radially spaced apart from the side wall of the mandrel 18C.
- the rotary drive contact of the base 11 by the mandrel 18 is obtained by close interlocking contact between the complementary connection zone 16A of the base and the connection zone 18B of the mandrel. Since the friction contact is ensured via the connection portion 18B of the bottom 11, it is possible to reduce the radius of the side wall of the mandrel 18C without reducing the radial dimension of the end of the side wall of the body container.
- Figure 4 illustrates a bead or bead 14 of triple crimping finished with seven layers or thicknesses of bottom plate or container body after the crimping tool 8 ′ has been partially withdrawn in its recoil movement towards the starting position (not shown).
- the frustoconical skirt 16 is deformed into a substantially cylindrical configuration, as shown, due to the action of 'drive radially inward of the crimping tool 8'.
- the internal surface of the skirt 16 bears completely against the tapered side wall 18C of the mandrel.
- the elastic withdrawal of the bead inevitably increases the resulting radial projection of this bead.
- the tapered side wall 18C of the mandrel according to the invention it is possible to further reduce the radial projection of this bead, the resulting skirt 16 of the bottom returning to a generally cylindrical configuration after elastic withdrawal.
- the angle ⁇ of taper of the lateral wall of the mandrel 18C is chosen so as to allow relatively easy disengagement of the mandrel after crimping.
- the taper angle a can preferably go up to 5 °, and is advantageously of the order of 3 °.
- the mandrel 18 can also be equipped with an extraction device generally used in the prior art so as to facilitate the withdrawal of the mandrel from the bottom of the container.
- the resulting radial projection of the finished triple crimp bead 14 relative to at the outer surface 2A of the container body is approximately four times the thickness e or e 'of the bottom sheet 11 and of the container body, that is to say approximately once the sheet thickness in less compared to the conventional triple crimp bead of FIG. 2.
- Figures 5, 5A, 5B, 5C, 5D, 6 and 7 show a second embodiment of the invention.
- the starting preformed container body 2 is the same as in the prior art of FIGS. 1 and 2.
- the bottom 21 is of a different configuration and comprises in the connection zone between the frustoconical skirt 26 flaring towards the bottom as shown and the hollow transverse central portion 25 a plurality of ribs 22 regularly or irregularly spaced in circumferential direction offset radially inward and axially inclined (see Figures 5 and 7).
- the radially inwardly facing surface of these ribs 22 is curved in the plane of FIG. 5 so as to match the curvature of the curved convex connection portion 28B of the mandrel 28.
- the rest of the frustoconical skirt 26 of the bottom 21 is further apart from the side wall 28C of the mandrel, which, as in the embodiment embodiment of Figure 4, is tapered down as shown.
- the annular contact zone 29A between the frustoconical skirt 26 and the adjacent portion of the container body 2 is likewise more radially spaced with respect to the lateral wall of the mandrel 28C.
- the contact zone between the mandrel 28 and the bottom 21 is circumferentially interrupted and alternates with the non-ribbed curved zones of connection between the container body 2 and the bottom 21. This arrangement is satisfactory with regard to the necessary engagement contact. rotation without sliding of the bottom 21 on the mandrel and centering of the container body 2 on the bottom 21.
- such preformed bottoms 21 are easily stackable. Due to the arrangement of the embodiment of Figure 5 the circumferentially alternating ribs 22 are adapted to come into contact with the convex face of the curved connecting zone 26A 'of the underlying bottom 21'. In this way the central portions 25 and 25 'are axially spaced from one another as are the flanges 27 and 27'. It will immediately be appreciated that this arrangement facilitates the manipulation of the preformed bottom and avoids the problems which traditionally arose in the prior art. Obviously, for the precipitated reason, it is preferable to choose the circumferential dimension of the ribs to a value greater than that of the non-ribbed curved connecting zones with which they alternate. Therefore, regardless of the angular orientation, there is a high probability of contact between the inclined ribs 22 and the underlying non-ribbed curved areas of connection 26A '.
- FIG. 5A shows a first step in the formation of a triple crimping cord, in which a first crimping tool 8 "is moved radially inwards so as to form an annular hook 17A, and the entire portion radially outside of the sidewall 27 is brought above the free edge of the rim 3 of the container body.
- the entire bead 24 tends to spring back slightly radially outward due to the inherent resilience of the skirt 26 and the adjacent end portion of the container body 2 so as to provide a small annular space in the form of a wedge between the radially internal wall of the bead and the facing portion of the lateral wall of the mandrel 28C.
- the initial ribs 22 are flattened in the skirt area against the side wall of mandrel 28C and remain only, after crimping, in the curved connection area.
- Figure 8 shows a preformed bottom 31 engaged on a mandrel 38 and a preformed container body 32.
- the radius of curvature R1 of the connection zone between the side wall of the container body 32 and the rim 33 of the container body is smaller than in the precipitated embodiments.
- the bottom 31 comprises a hollow transverse central portion connected by a curved annular connection zone 36A to a frustoconical skirt 36-widening radially outwards, or downwards, with a half angle at the top which is greater than that of the skirts 16 and 26, this skirt being followed halfway between the central zone 35 and the rim 37 by a curved connection zone having a radius R2.
- connection region of the container body 32 of radius R1 is fitted into the radius connection region R2 of the bottom 31 due to an appropriate choice of these radii.
- the radius R2 is slightly larger than the radius R1.
- the container body 32 is in contact with the bottom 31 by the free edge of the container end rim 33 and in centering contact at 39A near the zone of infection between the frustoconical skirt 36 and the convex radius connection zone R2.
- the crimping is carried out as described above and the triple crimping bead thus obtained is shown in FIG. 9.
- the radial projection of the resulting triple crimping bead 34 beyond the nominal radius of the side wall 32A in this mode of realization is approximately two to three times the thickness e of the sheet.
- the particular configuration of the skirt of the preformed bottom 31 ( Figure 8) allows the side wall of the container body to be spaced from the side wall of mandrel 38C over a distance substantially equal to that of the previous mode of production and leads to a crimping bead whose radial projection is equivalent to that of FIG. 6.
- the general shape of the bottom 41 is substantially the same as in FIG. 3 and comprises a hollow transverse central portion 45 connected to a tapered flared skirt 46 by a concave curved zone 46A, this tapered skirt 46 being at its tower connected to a flange 47 extending radially outwards by a convex connection zone.
- the bottom 41 of FIG. 10 differs from that of FIG. 3 by a larger flaring angle of the skirt 46 relative to the skirt 16.
- the container body 42 includes a cylindrical side wall and a radial rim 43 at the end of an annular connection zone, as in the previous embodiments.
- the resulting triple crimping bead 44 is shown in Figure 11.
- the radial projection of this bead 44 relative to the nominal wall of the container body 42A is about 2 to 3 times the thickness e of the sheet.
- Figures 12 and 13 show a final embodiment for the formation of a triple crimping bead of reduced radial projection.
- the side wall and the rim 33 of the container body are substantially as in Figures 8 and 9, with a connection area with a relatively small radius.
- the preformed bottom 51 includes a hollow transverse central portion 55 which is surrounded by a concave annular connection area 56A in intimate contact with the curved connection area 58B of the end wall of the mandrel and with the side wall of the mandrel 58C.
- Halfway axially between the radial rim 57 of the bottom 51 and the central portion 55 is formed an annular step 52 which increases in diameter from the concave connection area 56A towards the convex connection area of the bottom 51.
- the area of contact 59A between the bottom 51 and the container body 32 is the radially outermost part of the step 52.
- the annular step 52 is slightly frustoconical and widens radially and axially outwards, or downwards as shown .
- the bead resulting from the triple crimping 54 is similar to that shown in FIG. 9.
- the radial projection of the bead beyond the nominal wall of the container body is between two to three times the thickness e of the sheet .
- FIG. 14 shows the principle of the present invention applied to the assembly of a bottom 61 at the end of a container body 62 with a conventional double crimping bead 64.
- the double crimping tool 8 "" is classic.
- the mandrel 68 has a wall 68C tapered axially outward, or downward, which, before crimping, is radially spaced from the side wall of the container body over a distance greater than the thickness of the bottom 61 as shown in any of the previous embodiments.
- the lengths of the edges of the preformed container body and of the preformed bottom are to be dimensioned in accordance with a double crimping.
- the radial projection of a double crimping bead 64 relative to the nominal side wall of a container body 62A is practically zero and for this reason allows optimum storage capacity for drums in a given space.
- the double crimping 64 can be adapted in certain uses although the person skilled in the art may prefer a triple crimping barrel because of the reinforced resistance of the bead which is associated with it.
- the frustoconical zone formed in the side wall of the container body spaced axially inwards relative to the crimping cord may prove to be beneficial.
- the present invention is easily applicable to container bodies of different sections, for example polygonal, in particular.
- the preformed bottoms and the container bodies described above are preferably obtained as illustrated by stamping operations well known in the prior art.
