Definitions

  • the invention relates to a device for roll flanging cylindrical body, at least in the edge region, with several flanging rollers that can be rotated in one holder are stored and on the cylinder jacket to be formed Roll the body and by their contour the Form the flange geometry, and the outside diameter of the flange defining limiting tool arrangement, which - from the longitudinal axis of the Shot seen - is arranged outside the flanging rollers.
  • Flaring cans provides a preparatory Working method in which the cylinder jacket of the Can body in the area of the limiting edges over the entire circumference is reshaped.
  • the shaped bead is particularly due to the flare radius, which is the outlet contour of the can connects, and one primarily uncurved and mostly largely vertical end region of the flange aligned with the cylinder axis certainly.
  • US-A-5 150 595 - limiting rollers used in the same Recording are rotatably mounted as the flanging rollers, namely, from Seen the center point or the axis of the receptacle, radially behind a flanging roller, and on the other one coaxial to the longitudinal axis of the can body Bounding ring, which with its inner jacket Surrounds flanging rollers.
  • the diameter of both the inside of the boundary rollers, imaginary envelope cylinder as well as that of the inner jacket of the limiting ring is equal to or slightly larger than the diameter of the around the flanging rollers at their largest diameter imagined envelope cylinder.
  • the end of the can body becomes bent outwards until it has a diameter that corresponds to the Inner diameter of the inner envelope cylinder of the limiting rollers or Bounding ring corresponds.
  • the flanged material can the flanged material or Penetrate the cut burr of the treated workpiece.
  • Coatings of the crimping device parts can to be damaged. There is also an uncontrolled threat Take the can body with the flanging rollers the consequence of deformations and stronger Unevenness of the flare.
  • the device described in claim 1 solved which is characterized according to the invention in that the limiting tool arrangement an integral, sleeve-shaped limiting body has, with parts of the common longitudinal axis of the Device and the cylindrical body facing inner surface cylindrical parts of the flanging rollers that form the flanging geometry formed envelope around the longitudinal axis between adjacent Flaring rolls protrude inwards.
  • the limiting tool arrangement has a plurality of delimiting bodies at least when the maximum flange diameter between adjacent ones is reached Flanging rollers are arranged and with their, the common Longitudinal axis of the device and the cylindrical body facing The lateral surface is the cylindrical through which the flange geometry is formed Parts of the flanging rollers formed envelope surface about the longitudinal axis mentioned protrude inwards.
  • An essential core idea of the present invention is it, a jacket-side limitation of the flange to provide that not the previous boundary ring or the corresponds to previous limiting roles.
  • the limiting tool arrangement according to the invention can be in one piece as a sleeve body with recesses or windows for the the parts of the flanging rollers that form the flanging geometry be trained. But its inner surface can also one parallel to the common longitudinal axis trained waveform to order with parts between adjacent flanging rolls pass.
  • the boundary body surface is like this be designed so that the flange running there is performed with little friction.
  • you can also individual between the flanging rollers Boundary body can be arranged, the smallest common inner shell diameter the cylindrical, through the parts of the flange forming the Crimp rolls formed overhangs inside.
  • Limiting bodies are also only at the time Attachment to the flare to which the Flare bend is formed, which is why it is principally is possible, limiting bodies in question clock-controlled star-shaped at this time to move towards each other to get the maximum around Limit flange diameter.
  • the limiting body be designed to be stationary or capable of rotation.
  • the Training to rotate bodies, in particular individual limiting bodies has the advantage that Entraining movements of the limiting bodies are controllable, which is the friction of the flange on the limiting bodies minimize.
  • the limiting bodies are preferably cylindrical, so that they essentially each flare lead tangentially limiting.
  • each pair of flanging rollers placed side by side at least one delimiting body is provided which "on Gap "is set.
  • each limiting body as rotatable stored role designed, possibly with a own drive, can take advantage of lower rolling friction can be used. Especially for motorized roles and in terms of constructive arrangement it is recommended the axes the limiting rollers to a circle or one To lay cylinder jacket.
  • the flanging rollers and limiting rollers are preferably stored in a common receptacle, the one coinciding with the can axis central axis are rotatable.
  • the limiting roles in terms of changing the Distance of their axes of rotation from the central longitudinal or Rotational axis of the recording can be moved arranged, preferably in guide pieces or by an eccentric bearing.
  • the active surfaces are preferably Limiting rollers shaped in such a way that in addition the limitation of the flange dimensions through them additional flanging can be effected. Both the Flanging rollers and the limiting bodies then serve the flanging.
  • the device for roll flanging cylindrical body consists essentially of several - here eight - flanging rollers 10, the longitudinal or Rotation axes 11 on a common pitch circle 12 are arranged.
  • the flanging rollers 10 each lead a rotational movement (see arrow 13) and roll along the can body 14 or along the emerging flare B.
  • the flanging rollers 10 have a lower cylindrical part 15 with a larger one Diameter through whose shoulder or collar 16 the Flare B is formed on the can body 14.
  • the Crimping rollers 10 are on the can body facing end conical, with the Part 15 first a steeply conical part 10 'and then connect a flat conical tip 10 ''.
  • the Limiting rollers 17 are radially displaceable, what translationally by guide pieces 20 or by a eccentric storage can be done.
  • the Boundary rollers 17 are - at least at the time of Contact with the flare B to be produced - see above led them on a respective Bisector between the flanging rollers.
  • the flanging rollers 10 and the limiting rollers 17 are stored in a common receptacle 22, which is a centric, coinciding with the can axis Longitudinal axis 23 rotates.
  • the result of the flanging process resulting largest diameter can be by the position the limiting rollers 17, namely the determination of the Radius of the pitch circle 19 on which their Axes of rotation 18 are set.
  • At predetermined, fixed arrangement of the flanging rollers 10 in the receptacle 22 can by changing the Diameter of the pitch circle 19 the geometric Formation of the flange B, d. H. the flare width to be influenced.
  • the limiting rollers 17 are also driven (see arrow 21) so that between the flanging rollers 10 on the one hand and the limiting rollers 17 on the other no relative speed to the can body 14 consists.
  • the directions of rotation of the flanging rollers 10 and Limiting rollers 17 are opposite in this case.
  • the crimping device To a limited extent also for the crimping device to be able to use other can diameters provided on the flanging rollers 10 in the for Limiting rollers 17 described manner in the sense of Change in the diameter of the pitch circle 12 in the Arrange receptacle 22 displaceable and adjustable.
