Definitions
- the technical field of the invention is the method for forming metallic cover rings, which are required for fitting and flanging onto a container of round or non-round nature.
- cover rings are punched out of flat sheet metal, a round blank being formed in the middle, which represents waste; only the cover ring is required for the further production of the container.
- the invention is based on the creation of a cylinder ring (ring blank) which has not yet been completely formed and which arises from a can body, produced with a pull-in tool or a telescopic tool.
- a step tool can also be used to form the ring blank.
- the can body is formed from a sheet metal cutout in a round and non-round design.
- a ring blank is to be understood as meaning cylinder segments which are not necessarily circular, but which have a wall height which clearly extends in the axial direction.
- a cylinder is also understood to be a non-round cylinder which is oval, with the wall remaining constant in the axial direction.
- Cylinder segment corresponds to the amount of material that is provided for the formation of the cover ring.
- the shape of the cutting line T follows the shape of the ring blank.
- the cylinder segment is brought into a compilation of several ring-shaped tool segments and moved axially downward to form it via a deflection cliff in a radial direction, where it becomes a radially inwardly deformed and radially extending cover ring.
- the deflection via the deflecting cliff takes place in such a way that the downward / inward deformed cylinder segment is pressed into a gap which is defined by an upper and an underlying tool segment.
- the forming process transforms the cylindrical blank (in a circular to oval base shape) into a flat ring blank (claim 6), which additionally experiences an erected ring wall with an inner roll in an upward gear of another ring stamp.
- a cylindrical recess (claim 10) is adapted to the basic shape of the cylindrical blank, it can also have an oval basic shape, but with an axially clear extension to accommodate the cylindrical blank and move it downwards.
- the radial extent of the recess is adapted to the thickness of the cylinder segment to be formed.
- Figure 1 illustrates a first can in section, from which a ring can be separated.
- FIG. 2 illustrates an almost finished can which was created in the pulling process or in the pulling process, in which the pulling or pulling process was interrupted shortly before the end in order to obtain an upper cylindrical ring with a larger diameter.
- Figure 3 illustrates the separation at the ring dividing line T, with a residual
- FIG. 4 illustrates the finished cover ring with a horizontal
- the inside of the cover ring is open, which is illustrated by the opening 21 which can be seen in section. 5a, 5b, 5c, 5d,
- Figure 5e illustrate various positions of a single stage
- FIG. 6c illustrate a first tool of a multi-stage tool, in which the cover ring is first formed from a cylindrical shape in FIG. 6a into a horizontal shape with a wall 13 set up vertically on the inside according to FIG. 6c.
- FIG. 7 illustrates the second tool of the step tool, in which the cover ring 100 which is being created is trimmed on the inside.
- FIG. 8a illustrate the third stage of the step tool, in which the cover ring receives its inner curl 20e (here 15).
- the pulling or pulling process is stopped shortly before its end (approximately 80% to 95% before the end of the last reducing process) in order not to retract the diameter of the upper edge 40a of the fuselage to 2xr 1 .
- the edge region 40a remains as a blank cover ring VR when it is severed at T (dividing line).
- the dismantled fuselage 30/40 in the remaining fuselage 30 and cover ring blank 40 is illustrated in FIG.
- the dividing line T which is shown both in FIG. 1 and in FIG. 2, corresponds to the circular or oval basic shape of the container 30.
- the separation takes place from above in the case of a container formed in the pull-in pull, the pull-in not yet completely ending has been conducted.
- the separation is carried out from above or below at the dividing line T, the last reduction process, for example in the case of production with a telescopic tool, or the last step of a step tool not being completed, so that the cylindrical blank is above the fuselage 30 remains while he remained next to the fuselage in Figure 1, but in both versions with a larger diameter than the finished reduced fuselage.
- the further processing of the ring blank 3 into a finished cover ring 4 can be carried out either by a single-stage tool 5 or by a multi-stage tool.
- the first stage can be seen from FIGS. 6a, 6b, 6c, the second stage from FIG. 7, the third stage from FIGS. 8a and 8b.
- the transfer between the stations takes place e.g. B. via a gripper transport.
- the function and mode of operation is explained and supplemented using the following examples of tool designs.
- Figures 5a to 5e show the operation of the single-stage tool.
- the ring VR separated from the can is placed mechanically or by hand on part 5 from FIG. 5a.
- the tool parts 2, 3 and 4 are then moved into the ring by the machine stroke and form a gap S of 0.8 x sheet thickness to the parts 5, 6 and 7.
- the parts remain in this position until the shoulder 1 a of the
- Stamp 1 has inserted the sheet metal ring in the axial further decline of part 1 so far radially v n 'that the sheet metal ring VR.10 has reached the horizontal position in FIG. 5b.
- sheet metal is pulled in the direction ⁇ 2 and the ring wall 20d is set up.
- the parts 2 and 3 following parts 5 and 6 press the set-up 20d of the cover ring into the rolling groove 4a of the rolling ring 4. Since the forces of parts 5 and 6 and of the counteracting rolling ring 4 are greater than the deformation resistance of the Sheet metal material, an inner roller 20e of the cover ring is formed in the roll groove 4a of the roll ring 4 by the ripening of the cover ring assembly. After completion of the stroke, the cover ring has taken the form of Figure 5e. The part 3 is then relieved of force, the parts 1, 2 and 5 move back into the starting position. When the tool is moved apart, the ring shown in FIG. 4 is ejected.
- FIGS. 6a, 6b, 6c, 7 and 8.8a represent the manufacture of the cover ring in three or in several possible operations. The manufacture can take place both on individual presses and on step or transfer presses.
- the ring (FIG. 3, top) separated from the can (according to FIG. 1 or FIG. 2) is fed to the tool station (FIG. 6a) and positioned on part 5.
- part 2 is initially centered on the inner region 40b of the sheet metal ring 100.
- part 2 and part 5 (without sheet metal) form a gap of 0.8x sheet thickness.
- part 1 passes over the outer region 40a of the sheet metal ring 100 and pushes the ring with the shoulder 10 through the part 5, which is subjected to a holding-down force and which forms a gap S ⁇ sheet thickness with part 2 up to the inner diameter of the finished cover ring.
- the sheet metal ring 100 then has the shape of FIG. 6b.
- the punch 8 simultaneously reaches its end position and, with its cutting edge 12, squeezes the sheet metal into the recess provided for this to approximately a depth of 0.5 ⁇ sheet thickness over the cutting edge 11 of part 7.
- part 1 is pressed down.
- Part 2 follows part 5 with the hold-down force applied. Because the sheet metal ring is clamped in the area of the cutting edges 11, 12, the sliding process changes into a drawing process during the continued stroke. As a result, the set-up 13 for the following inner roll of the sheet metal ring 100 according to FIG.
- the axially erected wall 13 (cf. 20d in FIG. 5d) is produced by pulling, which has advantages over the thrust of FIG. 5c if the radii become larger.
- the preformed sheet metal ring 100 is transported into the trimming station and placed on the lifting ring 6 '.
- the shaped ring 2 and the holding-down ring 9a bring the preformed sheet metal ring 100 into position so that the subsequent punch 8 'can cut off the inner edge 100r via the cutting punch 9b.
- An inner cutting edge 100k remains. The separated ring 100r is removed by the lower tool.
- the trimmed sheet metal ring according to FIG. 7 is then transported to the finishing station of FIG. 8 and placed on the parts 5 'and 6' which are flush with the top.
- the parts 2 'and 3' coming from top to bottom during the press stroke are also flush when viewed from below and center with the inside dimension of part 3 'over the outside dimension of the set-up 13 of the bending ring 100. If the set-up 13 inside via part 7 outside is fully centered, part 6 "remains on a stop, part 3 'springs back on the sheet metal ring 100 and part 6' during the further tool descent. Part 5 'then forms the edge of the sheet metal ring 14 to the lower one via the sheet metal holder 2' Dead point of the press.
- This multi-stage production is particularly suitable for cover rings with a wider radial flange 20c.
