Definitions

  • the invention relates to a machine for flanging and pulling cylindrical can bodies on both sides according to the preamble of claim 1.
  • the aforementioned machines are known (prospectus Lanico "flanging and drawing-in machine BEA 6-325"), which are designed as fully automatic machines and in which the can bodies pass through the machine in the horizontal position of their axes.
  • a number of planetary orbiting stations are provided with the crimping and retracting heads mentioned in the generic term, each of which can be inserted in opposite directions into the respective can body, as well as assigned swivel arms and control cams.
  • the can bodies When the retracting and flanging edges are formed, the can bodies are laterally displaced by the pressure and the radial evasive movement of the swashplate relative to the aligned longitudinal axis of the flanging and retracting heads or the associated spindles engaging in the respective can body. If only one end of the body of the can is drawn in with a flanged edge, while the other end of the can is drawn into a non-drawn or less drawn If the flanged edge is deformed, the can body is inclined with respect to the longitudinal axis of the co-operating spindles.
  • the can body Due to the evasive movement of the swashplate or swashplate and the flaring and retracting roller acting on the can body and the swashplate only at one point on the circumference of the can, the can body is no longer guided exactly during the described displacement or inclination.
  • a so-called abutment bell in the form of a ring element has been arranged axially behind the swash plate on the spindle, which forms a bell-shaped ring surface facing the edge of the can body, on which the end edge of the body end forms during the first part of the deformation of the body end supports, so that the evasive movements of the fuselage are kept within limits during part of the deformation of its edge regions.
  • the invention has for its object to develop a machine of the type mentioned in the introduction so that the shaping of the flanging and pulling-in edges of the can bodies is achieved with greater accuracy and, moreover, the deformation of can bodies from double-reduced sheets or other sheets with a Rockwell hardness of 60 HR 30T or greater hardness can be provided with the retracting and flanging edges in one operation.
  • the machine is characterized by the features mentioned in the characterizing part of claim 1.
  • the can body to be machined can be accommodated between the cooperating flanging and retracting heads in such a way that it is supported at least with one end on the outer annular disc of the swash plate and by further opposing, axial movement of the interacting flanging and Retracting heads cause an axial displacement of the outer washer with simultaneous engagement of the inner washer in the rim of the can body to be flanged.
  • the end region of the can body lies on the outer circumference of the inner washer before the flanging and drawing-in roller is brought into contact with the can body.
  • the end region resting on the inner ring disk becomes hook-shaped angled and pressed by the spring washer outer washer clamping against the flanging and retracting roller and thereby held in contact with the flanging and retracting roller, even during the further deformation process until the flanging and retracting roller interacts with the peripheral surface of the inner washer .
  • the flanged edge is essentially already formed.
  • the retraction is formed with radial displacement of the two ring disks forming the swash plate, the outer edge zone of the flanged and retracted edge of the can body always being held under the action of the outer ring disk under spring pressure.
  • the can body is securely guided in the region of its retracting and flanging edge during the shaping of the edge and is held in a clamped manner with the swashplate with its end edge zone in the region of the interacting flanging and retracting roller.
  • the two flanging and pulling-in heads that interact in each case can be designed according to the invention, with flanging and pulling-in rims of different depths being usually required or desired at the two ends of a can body.
  • outer ring disk has an L-shaped cross section, the short leg of which forms an outer axially projecting ring section of this ring disk for the mutual guidance of the ring disks.
  • the sleeve can have an inwardly facing annular shoulder as a stop in a simple manner, which interacts with an annular end face formed by the spindle.
  • the disc-shaped abutment on its side facing the swashplate bevelled to provide the outer edge.
  • This chamfering serves as a contact and abutment surface for the transition area mentioned from the pulling-in and flanging edge into the undeformed can body.
  • the drawing shows an embodiment of the invention.
  • the machine shown in FIGS. 1 to 3 consists of two drive units 1 and 2, which are held on a base and controlled by a synchronizing device so that they drive the central shaft 3 together.
  • the guide disks 4 have recesses for the tools (not shown in FIGS. 1 to 3) for drawing in and flanging the ends of the can bodies.
  • the drive unit 2 is held for adjustment to different lengths of the can bodies in the direction of the double arrow shown above the unit on the base frame.
  • FIGS. 1 and 2 The machine shown in FIGS. 1 and 2 is equipped according to FIG. 3 with six planetary stations 5, to which the can bodies 7 are fed via a feed trough 6.
  • an additional feed channel 6 ' is provided in order to ensure the continuous operation of the machine if possible.
  • FIGS. 4 to 7c The structure of the flanging tools of the individual stations 5 and their mode of operation can be seen from FIGS. 4 to 7c.
  • FIG. 5 and 6 show that in the individual stations 5 the can bodies 7 are held by crimping and retracting heads 8 and 9 which can be axially inserted in opposite directions.
  • Fig. 5 only one of the units 1 and 2 is shown in partial section, since the other drive unit has the same structure as that 5 shown in FIG.
  • the flanging and retracting head 9 is connected to a spindle 11 which can be driven in rotation.
  • the spindle 11 is in turn held or supported in a thrust sleeve 12.
  • feed rollers 13 are connected in a rotationally secure manner, which engage in a groove 14 of a ring part 16 held stationary in the housing 15.
  • a guide sleeve 17 connected to the thrust sleeve 12 is firmly connected, which in turn interacts with a guide track 18 which rotates with the central shaft 3.
  • the thrust sleeve 12 is held in an annular bearing part 19 connected to the central shaft 3.
  • each crimping and retracting head 8 or 9 is assigned a pivot arm 26 held in an annular bearing part 19 (FIG. 4), which can be connected in a rotationally secure manner to a pivot axis 27 (FIG. 5), which in turn can be rotated via a cantilever arm 28 and on the latter held cam rollers 29 and 30 cooperates with a cam 31.
  • the control curve 31 is held in the ring-shaped component 16 in a rotationally secure manner.
  • a flanging and pull-in roller 32 is provided, which is held on an axis of rotation 32a of the swivel arm 26.
  • the crimping and retracting head 9 is connected to the spindle at the free end according to FIG. 6 in a rotationally secure manner and has a disk-shaped abutment 20.
  • a swash plate consisting of two concentrically interlocking ring disks 21 and 22 of different external diameters.
  • the outer washer 21, which is larger in outer diameter, has an L-shaped cross section and thus forms a stepped annular shoulder 23, which serves to guide the two washers 21 and 22 with one another during their mutual axial displacement.
  • the ring disk 21, which is larger in outer diameter, is supported on a sleeve 24 guided axially on the spindle 11 and displaceable along the spindle 11 against a spring 25.
  • the inner ring disk 22, which is kept smaller in diameter, is supported on the side opposite the disk-shaped abutment 20 on a cone part 33, which in turn is under the action of a spring 34 which tries to press the ring disk 22 against the disk-shaped abutment 20.
  • the washers 21 and 22 have, on their outer circumference, boundary surfaces 21a and 22a adapted to the shape of the flanging edge, these boundary surfaces corresponding approximately to the radial pressure surface of the flanging and retracting roller 32.
  • the sleeve 24 is limited in its axial displacement against the action of the spring 24 by a stop which is formed in the example shown by an inwardly facing annular shoulder 24a.
  • the displacement of the sleeve 24 is determined by the width of the gap 34a. This displacement path is smaller than the depth of engagement of the washer 22 in the washer 21 of the swash plate.
  • the swash plate i.e. the ring disks 21, 22 facing the outer edge with a chamfer 20.
  • the outer diameter of the annular disk 22 is kept equal to or smaller than the inner diameter of the can body 7 to be flanged.
  • FIGS. 7a to 7c The interaction of the flanging and drawing-in head 9 according to FIG. 6 with the flanging and drawing-in roller 32 can be seen from FIGS. 7a to 7c.
  • the flanging and pulling-in roller 32 is pivoted against the flanging and pulling-in head 9 and forms the narrow edge zone 7a of the can body 7 in a hook-like manner into a narrow, radial flange, the washer 21 being acted upon by the spring 25 for a firm pressure the hook-shaped edge zone 7a on the flanging and pull-in roller 32 ensures that springback is not possible. While maintaining this clamping effect the hook-shaped in the form of a flange outer edge zone 7a, the retraction and flanging roller 32 is further advanced to the position of FIG.
  • the design of the flanging and drawing-in head 8 shown in FIG. 6 differs from the flanging and drawing-in head 9 in this example.
  • the flanging and retracting head 8 is conventionally equipped with a one-piece swash plate 35 which is surrounded axially offset by an annular abutment bell 36 on which the other end of the can body 7 provided with the flanging and retracting edge is located at least over the first part of the Flanging and pulling-in process supports when the flanging and pulling-in roller assigned to this flanging and pulling-in head 8, not shown in the drawing, interacts with the swash plate 35.
  • the formation of only one flanging and retracting head according to the invention is sufficient.
  • the two retracting heads it is also possible for the two retracting heads to be of the same design, the difference Liche depth of the retraction can be achieved by appropriate training of the washers and the feed movement of the flanging and retracting roller.
