Definitions

• the invention relates to a method for producing or machining a workpiece in the form of a cylindrical hollow body, in particular container (casing), barrel or barrel, in which the workpiece is held with a vertically aligned longitudinal axis and processed in this orientation, in particular deformed, flanged, with beads , Bottom and lid is provided.
• the invention further relates to a device for producing or processing a workpiece in the form of a cylindrical hollow body, in particular a container (casing), barrel or barrel, with a transfer device for moving the workpiece and a processing device for producing or processing the workpiece, in particular a device for shaping , Flanging, beading and provided with bottom and lid, and with means for holding the workpiece during machining in an orientation with a vertical workpiece longitudinal axis.
• the machining takes place on one or more or preferably at the same time on both front edges of the workpiece. It can be creasing, flanging or connecting with a lid or bottom.
• a drum-shaped metal shell or container casing can be firmly closed as packaging for any filling material with a loosely inserted bottom and lid, the closing of a cold or hot deformation being possible, the projecting metal edges being connected to one another or being deformed and folded together.
• the known procedure has the disadvantage that the heavy tools and drive units must be attached to appropriately stable portals, which involves considerable costs.
• the object of the invention is to make a generic method or a corresponding device simpler and cheaper.
• this object is achieved by moving the workpiece in a transfer plane and lowering it for machining in a work area of a processing device, in particular a shaping machine, arranged below the transfer plane.
• a processing device in particular a shaping machine, arranged below the transfer plane.
• the workpiece is preferably lowered for machining with a vertical longitudinal axis and moved in the transfer plane with a vertical longitudinal axis.
• the workpiece can be machined from the inside and / or from the outside in the machining device. It can be provided that the workpiece is machined in the machining device over the entire axial length or a part thereof.
• the workpiece can be lowered and processed in stages.
• the workpiece is lifted after machining and moved back into the transfer plane, the workpiece being able to go through several machining steps (lowering, machining and lifting) on several machining devices.
• the workpiece can be moved past selected machining devices without being machined.
• Non-round or conical workpieces or containers can be produced, and workpieces can be made from sheet metal, multi-layer glued cardboard (fiber) or multi-layer metal-plastic sheets.
• the object of the invention is achieved by a generic device which is characterized in that the transfer device is arranged vertically above the processing device and is designed such that a workpiece to be processed can be lowered into a working area of the processing device. It can be provided that the transfer device moves and / or lowers the workpiece with a vertical longitudinal axis.
• the processing device expediently processes the workpiece from the inside and / or from the outside, in particular flanging the workpiece on both sides or flanging on one side and flanging on the other side. It is preferably provided that the processing device provides the workpiece with rolling and / or reinforcing beads.
• Figures 1 and 2 schematically serve to explain a container to be processed
• Fig. 3 shows schematically a device according to the invention
• FIG. 4 schematically shows a known device in which a workpiece is machined with a vertically aligned longitudinal axis
• Fig. 5 shows schematically a known device in which a cylindrical workpiece with a horizontal workpiece axis is machined
• FIG. 6 shows a top view of a known molding tool.
• FIG. 1 shows a rounded and closed with a longitudinal weld or a longitudinal fold container casing, which can consist of steel or other metal sheet, but can also be made of fiber (multi-layer glued cardboard) or multi-layer metal-plastic sheets.
• FIG. 2 shows a cylindrical container with a longitudinal axis 1 produced from the container jacket according to FIG. 1, the container consisting of a cylindrical container jacket 4 with bottom 5 provided with rolling beads 2 and reinforcing beads 3.
• Fig. 4 shows schematically a container manufacturing machine, in which the central or longitudinal axis 1 of a container is vertical during shaping or production, the container jacket 4 for shaping from a transfer device 7 or by hand into the working area of a portal processing tool 8 hanging above the transfer device is lifted.
• 5 explains a further known manufacturing method for containers, wherein a container casing 4 with a horizontal longitudinal axis 1 is processed, tools 8a processing the container casing 4 from the inside and tools 8b processing the container casing from the outside, so that, for example, beads can be introduced.
• the lowering can take place with the full length of the container or in stages over parts thereof.
• the drive units and shaping tools are located directly near the ground, while the light transport or transfer device 7 is arranged above the machine.
• a number of shaping machines can be arranged in a row, the individual machines for carrying out flanging on both sides (upsetting the edge), flanging on one side and bordering on the other side (rolling on the edge), pressing out any number of roll beads in different positions of the container casing, roll forms of any number of stiffening beads in different positions, folding of floors and / or lids or for welding floors can be set up.
• the containers or container casings which are moved on the transfer device 7 in the transport direction (arrow 12) are lowered over the tools of the respective machines (arrow 14) and lifted back onto the transfer device after shaping or processing.
• individual shaping machines can be run over and left out.
• the container jacket guide elements are simpler and less complicated and also enable the shaping of non-round or conical container jackets.
• the device has a rolling body 32 and a counter-rolling body 31, the two rolling bodies being complementary to one another and the counter-rolling body 31 being fixed in place.
• the rolling body 32 is one Pivot point 37 is held pivotably.
• the outer surfaces of the rolling elements are made up of a number of annular disks 33a, 35a, 35b.
