  • - Tubes means in particular longitudinal seam tubes or longitudinally welded tubes, which are formed from (metal) sheets in several stages and then welded along a longitudinal seam to the tube.
  • the sheet is pre-bent or bent in the region of the (two) longitudinal edges.
  • the bending radius corresponds to z. B. approximately the diameter of the tube to be produced.
  • Press means in the context of the invention in particular a hydraulic press for bending sheet metal in such a (first) forming stage.
  • the sheets prepared in this way are then usually bent in a second stage in a so-called U-press to a U-shape.
  • the U-profile is formed in a so-called O-press in a further operation to a round tube or slot tube.
  • the welding of the longitudinal seam can follow from inside and / or from outside.
  • the bending of the sheet longitudinal edges in the first forming stage represents an important step in the process of pipe production, so that optimization of this step leads to an optimization of the pipe production.

  • Pressenlvonsraum means the direction along which the sheets fed to the press or from be removed from the press. It is usually the direction that is perpendicular to the plane of the press frame.
  • the actuators for the tools are preferably designed as hydraulic cylinder piston assemblies. However, they can also be designed as spindle drives.
  • the press frames are closed press frames. Closed press frame means in particular made of closed frame plates press frame, said frame plates then have a top rail, a lower rail and two-sided connecting spars.
  • Such frame plates may be made in one piece or even from a plurality of sheet metal sections, which may be welded together, for example.
  • the closed press frame can also be formed in the sense of a column press of each upper spar, lower beam and the upper spar and the lower spar interconnecting press columns.
  • the invention is initially based on the recognition that the pressing forces occurring in the course of forming can be particularly well absorbed when working with closed press frame, so that consequently a frame at the same time receives the pressing forces that arise in the region of both longitudinal edges.
  • This is particularly advantageous when forming sheets of relatively large thickness to produce pipes of large thickness.
  • the frame construction succeeds in a simple way an adaptation of the press to different conditions and in particular different sheet widths and different bending radii.
  • the tool carrier and thus also attached to the tool carrier tools are adjustable within the press frame and therefore freely positioned. Such a positioning succeeds in the sense of a remote adjustment, so that no elaborate manual adjustments are required. Rather, the tool carrier or the tool carrier can be positioned by external control in the desired manner.

If the actuators are designed as cylinder piston assemblies, it is within the scope of the invention, the possibility of the piston or the piston rod of the cylinder piston assemblies fixed or fixed to the upper or lower press table to connect, and the tool carrier fixed to the cylinder or
  • the upper and / or lower press table have at least one (central) support bracket, on which the or the actuators are supported or held.
  • the invention is based on the finding that two upper tool carriers and two lower tool carriers are provided for the simultaneous processing of both sheet edges, wherein preferably each tool carrier is assigned its own cylinder piston arrangement or several separate cylinder piston arrangements. The two tool carriers for the two sheet metal edges are then arranged on both sides of the central support bracket.
  • the cylinder piston assemblies can work transversely from both sides on the support block or trestles.
  • each have a piston rod of the associated cylinder piston assembly may be connected.
  • This has the advantage that in the course of the bending of the two sheet edges introduced during the pressing in the tool carrier forces are taken up centrally of the support block and there are substantially compensated.
  • the invention is based on the recognition that the forces introduced essentially vertically into the sheet metal edges in the course of forming are diverted to a considerable extent into horizontal forces or transverse forces by the contour of the tools. These forces arising in the region of the two sheet metal edges are opposite, so that they are - when they are introduced in the common support block - compensated by and large. In the context of the invention is thus prevented that high forces must be absorbed by the frame and in particular by the vertical frame members or columns.
  • a particularly stable construction is ensured.
  • a particularly compact design can be chosen because the press frame can be constructed very compact by the force compensation. This makes it possible to preform large areas of the sheet already in the course of bending so that the subsequent method steps can also be optimized with the press according to the invention.

If, for example, the two cylinder arrangements associated piston rods are arranged on both sides of the central support bracket, it is advantageous if the piston and piston rods are clamped by means of the piston rods sweeping drawbars against the support frame, the tie rods are attached to the piston.
  • the two tubular piston rods arranged on both sides of a support bracket can be penetrated by a single common pull rod, which is fastened to the end of the piston and with which the two pistons and tubular rods are braced against the central support bracket and against each other.
  • the support bracket may have an opening through which the central pull rod is passed.
  • the cylinder piston assemblies are preferably designed as double-acting cylinder piston assemblies, so that each individual tool carrier independently is adjustable from each other. It is understood that a tool or z. B. on the press base of a sheet metal side associated cylinder piston assemblies are preferably operated synchronously.
