TH21441A - Methods for forming the body of metal containers - Google Patents

Abstract

A method for forming a metal container consists of forging metal cups (12) with sidewalls and protruding baseballs in the base wall. The protrusion has a transverse wall (14) and a ring wall (15) attached to the side wall of the cup (12). Metal rolling in the aforementioned ring wall (15) up against such transverse wall (14) to Form a common cross-section of the conical ring wall between the said transverse wall (14) and the side wall.

Claims (9)

1. The method for forming the metal cup through forging consists of hammering the metal cup that There are side walls and baseboards where there is a cylindrical protrusion in the plinth wall, with the aforementioned protruding the wall. Transverse indent when Compared with the base wall mentioned above And the part of the ring wall near the side wall of the cup and the re-forming of the aforementioned base wall by rolling the metal in the ring wall mentioned above. Then go to the top when Compared to the transverse wall mentioned above For forming the conical ring wall part is cut up. Between the aforementioned transverse wall and the aforementioned side wall 2. Method according to claim 1 consists of rolling the side wall of the hammer forming repeatedly to Forming a can 3. Method according to claim 2 will be continued by forming the inward dome part. Up in the base wall of the can already mentioned 4. Methods for forming a can include: forging a cup with a side wall and a base wall with a cylindrical protrusion with a transverse wall. Indent inward relative to the base wall mentioned above. And a ring wall connecting the transverse walls. The foregoing and the aforementioned base wall near the side wall of the cup; Repeat stamping The cup for diameter reduction, repeated forming of the aforementioned ring wall into a conical section of the wall that extends downward and into The inside from the side wall to the base wall mentioned above; Rolling the side walls above to reduce the thickness of the siding; And forming up in the base wall mentioned above 5. Method according to claim 4, repeated forging, extrusion and forging as mentioned Then the dome's upright will be performed in a single stroke of the hammer head. 6. Method according to claim 4, the aforementioned cup will be hammered from sheet material. Aluminum alloy with a thickness of 0.012 inches or less. 7. Methods for forming a metal container: Forging of a metal cup with siding and baseboards with a central transverse section, a ring-wall section. Cylindrical shape around the middle wall part mentioned. And has been connected to the outer wall part that Indent relative to the above cross-wall sections; And repeated stamping of the aforementioned metal cups For re-forming of the aforementioned ring wall part It is the conical wall cut between the previously mentioned center wall and the side wall of the re-hammered cup. 8. Approach according to claim 7, the aforementioned central wall part is re-formed as a domed part after repeated forging of the aforementioned cup. 9. Method according to claim 7, the side wall of re-molded cup will be rolled.
