Definitions

  • the invention relates to a method for producing a ring part from sheet metal for a Can lid.
  • This method has a number of disadvantages.
  • laser welding the Made of an organic material, heat-sealable coating that is on the Outside of the pipe is destroyed. Combustion products of the coating get into the melt flow of the weld and cause a carbon enrichment in the Weld seam, which is associated with a hardening of the weld seam.
  • the hardening of the Seam is four to five times the hardness of the base material.
  • the Burning of the coating takes place explosively, causing holes in the Weld seam arise.
  • To ensure the sealability in the weld area is it is necessary to repair the weld area with a new coating.
  • Another disadvantage is that the high hardness of the weld seam the formability reduced and leads to increased wear of the forming tools.
  • FIG. 1 shows a ring part 1 with an outer flange 2 for not receiving one illustrated can body.
  • a cylindrical section closes on the outer flange 2 3, which merges into a radially inwardly extending annular surface, which acts as a support surface 4 serves for a tear film 5.
  • a curl 6 adjoins this bearing surface 4. This section is rolled up to form the curl 6.
  • the top of the ring part 1 is coated with a heat-sealable coating 7. This coating is thus also found on the top of the bearing surface 4, with which one flat heat seal 8 is achieved with the tear film 5.
  • the bottom of the Tear film 5 can also be coated with a heat-sealable coating 9, which also achieves a heat seal 10 with the curl 6. With that the Can contents protected from the bare end 11 of the curl 6.
  • the other side of the Ring part 1 and tear film 5 are provided with a lacquer layer 12 and 13, respectively. It should it is a sealable lacquer.
  • a flat sheet metal part is formed into a cylindrical tube 14, wherein the flat sheet metal part is pulled by means of clamping jaws 15 over a cylinder 16, whereby the axially extending edges 17 are pressed against each other.
  • the heat sealable Coating 7 is located on the inside.
  • the axially extending edges 17 are connected by means of a laser beam 19 Cooling plate 18 prevents the coating 7 from being destroyed in the region of the seam 20.
  • the pipe 14 is divided into pipe sections as described in DE 43 32 306 A1.
  • FIG. 3 shows a pipe section 21 to be formed into a ring part 1 internal coating 7.
  • a pipe section 21 is attached to the top molded conical widening 22.
  • the drawn section with 23 is designated.
  • the cylindrical Section 3 is the cylindrical Section 3 in place. The resulting molded part is shown in FIG. 6.
  • the conical widening 21 becomes an annular flange 24 towards the outside formed and the outer flange 2 is formed, which serves to accommodate the can body.
  • the inner end is simultaneously folded down, with which the support surface 4 is formed becomes.
  • the folded end is rolled up according to Figure 9 and forms the Enrollment 6.
  • the cylindrical tube 14 is provided with beads 25, the tube is then divided into pipe sections 21A, the subdivision in each case Area of a bead increase and a bead recess.
  • the upper region is flared and the lower region formed radially inwards.
  • the subsequent processing steps correspond to the Figures 7 to 9.
