Definitions

  • the invention relates to a device for rounding and conveying sheet metal blanks for can frames a first and a second bending roller, between which a sheet metal blank can be moved, a deflecting body arranged behind the bending rollers in the direction of movement of the sheet metal blank, on which the sheet metal blank can be deflected away from its original direction of movement away from the first bending roller and around the second bending roller, a catch strip for catching the sheet metal blank in the front edge in the original direction of movement, - At least one pair of conveyor links for axially moving the rounded sheet metal blank and - A guide rail, on which the rounded sheet metal blank is guided with its longitudinal edges close to each other during its axial movement.
  • each sheet metal blank to be rounded successively passes through a conveying station, a pre-bending station and a bending station.
  • Each of these stations has a pair of horizontal rolls arranged one above the other.
  • pre-bending bodies are arranged in front of and behind the roller gap, which ensure that the sheet is bent back and forth in order to then run into the bending station as stress-free as possible.
  • An upper and a lower guide body are arranged in front of the roll gap of the bending station, between which the sheet metal blank is guided.
  • a deflection body is arranged behind the roll gap of the bending station and bends the sheet metal blank around the lower bending roll.
  • a catch strip of hook-shaped profile is formed, which catches the front edge of the rounded sheet metal blank that is in the previous direction of movement.
  • the sheet metal blank is axially displaced by a pair of drivers, as a result of which its previously front and rear edges, which are now longitudinal in the new axial direction of movement, each fit into a groove of a guide rail of Z-shaped profile be inserted.
  • the guide rail begins at an axial distance behind the bending rollers and ends immediately in front of a pair of electrode rollers of a welding station, in which the longitudinal edges of the sheet metal blank are welded together.
  • the drivers that push the sheet metal blank away from the bending station into the guide rail of Z-shaped profile are arranged in pairs on an endless conveyor chain.
  • a further chain conveyor extends along the guide rail with drivers which are likewise arranged in pairs and push the sheet metal blank further forward until it is gripped by the electrode rollers.
  • the invention has for its object to make a device for rounding and conveying sheet metal blanks for can frames more space-saving than the known device described.
  • the object is achieved on the basis of a device of the type described in the introduction in that the catch strip on the side of the second bending roller facing away from the first bending roller is arranged at least approximately in the common plane of the axes of the two bending rollers and is a component of the guide rail, which extends at least approximately over the entire length of the two bending rollers and is arranged such that it is surrounded by the sheet metal blank when it is bent.
  • the sheet metal blank assumes a position which corresponds to, or at least comes very close to, that which is required for a subsequent connection of its longitudinal edges. It is assumed that the longitudinal edges are connected to each other in the usual way, e.g. by soldering, butt welding by means of an energy beam or in particular by an electrical resistance welding process, in which a pinch seam is produced.
  • the guide rail arranged according to the invention directly on the bending rollers, and preferably over their entire length, guides with its section acting as a catch strip both longitudinal edges of the rounded sheet-metal blank with its axial displacement from the beginning with an accuracy that behind known generic devices only behind at an axial distance the bending rollers is gradually reached when the longitudinal edges of the sheet metal blank are completely in the grooves of only behind the guide rail beginning guide, for example, are guided by a Z-shaped profile.
  • a conventional device for connecting the longitudinal edges of the sheet metal blank can be arranged at a small axial distance from the bending rollers, for example a device with a pair of electrode rollers, from which the sheet metal blank is gripped at its longitudinal edges, hardly that he has left the area of action of the bending rollers.
  • the guide rail is partially embedded in an electrode support arm of an electrical resistance welding machine, which is also surrounded by the sheet metal blank when it is bent.
  • the guide rail is expediently aligned with a Z-rail in which the longitudinal edges of the sheet metal blank are guided as it moves axially.
  • the space provided for rounding the sheet metal blank is delimited by shells, at least one of which is adjustable.
  • the nip between the bending rollers can be dimensioned and the deflector can be arranged in such a way that the edges of the rounded sheet metal blank, which extend in the axial direction, automatically attach to one side of the catch strip without the sheet metal blank having to be guided through the shells .
  • sheet thickness and hardness of the sheet blanks can vary within certain limits, it is expedient to arrange sheets according to the invention to ensure that sheets of different quality are also obtained at the end of the cut Take their intended position in relation to the guide rail.
  • the conveyor links provided for axially moving the rounded sheet metal blank can be arranged in a known manner on an endless conveyor chain or a pair of such chains.
  • additional installation space is required for this, and above all such chain conveyors cannot be accommodated in the desirable manner near the catch bar arranged according to the invention, along which the longitudinal edges of the rounded sheet metal cut slide as it continues to move axially.
  • the two conveying members are bars, which extend along the guide rail on one side of the catch rail, can be circumnavigated together with the latter by the sheet metal blank passing between the bending rollers, counter to the direction of further movement of the sheet metal blank can be pulled out of it and spread apart behind it in order to take it with it in a subsequent forward movement.
  • the features described above are therefore advantageous regardless of the manner in which the sheet metal blanks are rounded.
  • the latter embodiment is preferably further developed in that the two conveying members are pivotably mounted on a slide that can be moved back and forth in the longitudinal direction of the guide rail, - A rocker is also mounted on the slide in such a way that reciprocating movements of the slide are converted into swiveling of the rocker, and - Curves are arranged on the rocker, of which swivels of the conveying members are controlled towards and away from each other.
  • a push rod is arranged on the slide at a distance from the two conveyor members and essentially parallel to them outside the space enclosed by the rounded sheet metal blank, which, in addition to the two conveyor members and against them, with a pawl mounted on it Angle offset attacks at the rear edge of the rounded sheet metal blank. In this way, the feed forces required for axially moving the rounded sheet metal blank can be distributed evenly.
  • the carriage can be driven via a crank drive which has a crank attached to an output shaft and a connecting rod with two connecting rod parts which telescopically guided to each other and connected to each other by a latching device which triggers when overloaded.
  • the articulated coupling drive preferably has two cranks that bwz on the drive shaft. attached to the output shaft and connected to each other by a coupling member of adjustable length.
  • the length of the coupling element can be changeable, for example.
  • flat sheet metal blanks 10 are rounded cylindrically and welded at their edges parallel to the cylinder axis.

  • the sheet metal blank 10 which gets into the nip between the transport rollers 16 and 17, is pressed down by the pre-bending body 21, so that its front edge abuts against the lower transport roller 17. During the further movement in the direction 12 caused by the transport rollers 16 and 17, the sheet metal blank 10, with the exception of its front edge region, loses the bend forced on it by the pre-bending body 21; Most of the sheet metal blank 10 is bent downwards and upwards once, which reduces internal stresses. On the way from the transport rollers 16 and 17 to the bending rollers 24 and 25, the sheet metal blank 10 is guided between the table 20 and the cover plate 22. Before the transport rollers 16 and 17 release the rear edge region of the sheet metal blank 10, the front edge region which has remained curved downwards is gripped by the bending rollers 24 and 25.
