Definitions

  • the invention relates to a device for cutting flat materials according to the preamble of claim 1.
  • Such a device is known from DE-A-33 21 954.
  • a high-pressure liquid jet from a numerically controlled cutting nozzle cuts the material placed on a cutting table.
  • a collecting container is provided below the cutting table and tracks the cutting nozzle. This prevents wetting of the underside of the material to be cut, which is otherwise caused by the liquid jet, as a result of which this economical cutting method can also be used for the production of components for aircraft and spacecraft.
  • the invention is based on this known device and has the task of designing the cutting table for automatic disposition of the material to be cut. This object is solved by the features of claim 1.
  • the device according to the invention ensures a very good cutting material support due to the meandering and tensioned steel strip, which can be penetrated by the high-pressure liquid jet practically unhindered. This means that the cutting nozzle on the cutting table can be moved into any position, so that there are practically no limits to the disposition of the material to be cut on the cutting table.
  • the cutting device can therefore be used as a processing stage within an assembly line production, since there are no difficulties with the supply and transfer of material.
  • the cutting table consists of two endless chains 3, 4 guided around rollers 1, 2.
  • the roller 2 is driven by a drive motor 5, while the roller 1 serves as a pure deflection roller.
  • the material to be cut 6 is cut on the cutting table.
  • a collecting container 9 arranged below the cutting table is fed to the cutting nozzle 8.
  • the movement of the cutting table that is, the chain drive determining the unrolling of the material to be cut 6 from the supply roll 7, can also be used.
  • the links of the chains 3, 4 are each connected to outwardly projecting bolts 10, at the projecting ends of which two rollers 11 are attached. These rollers 11 engage to secure the distance of the chains 3, 4 in each case in a transverse web 13 of a circumferential, T-shaped guide groove 12 following the chain guide, which are provided on the machine base body.
  • a tab 14 having a plurality of bolts 15 is attached.
  • each tab 14 is provided with two tensioning and clamping devices 16, with each of which a thin steel band 17, which is guided around the bolts 15 of two opposite tabs 14, is tensioned and fastened.
  • the meandering steel bands 17 of all chain links therefore form a rotating cutting table which can be penetrated by the liquid jet 18 of the cutting nozzle 8 practically unhindered.
  • Stainless steel strip with a thickness of 0.1 mm to 0.3 mm and a width of 30 mm can be used for the steel strip 17.
  • the distance between the bolts 15 in the tabs 14 is dimensioned to double the bolt thickness, which can be, for example, 6 mm.
  • the device according to the invention permits automatic disposition of the strip-shaped material to be cut rolled from the supply roll 7 onto the rotating cutting table 6.
  • the steel strip 17 stretched between the plates of the distance-secured chains 3, 4 is sufficiently rigid so that cutting with the liquid jet 18 of the cutting nozzle 8 is unproblematic is.
  • This also applies to other separation processes, such as laser, air or steam jet separation processes.
  • the device according to the invention can therefore be used in automatic assembly line production without difficulty. It is also possible to replace the steel strip 17 with a steel wire or with a strip or a wire of a suitable material.
