Definitions

  • the invention relates to a device for cutting flat materials according to the preamble of claim 1.
  • a high-pressure liquid jet from a numerically controlled cutting nozzle cuts the material placed on a cutting table, in particular fiber-reinforced composite material.
  • a collecting container is provided below the cutting table, which is fed to 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 the device of the main patent (main patent application) and has the task of designing the cutting table for automatic disposition of the material to be cut. This object is achieved by the characterizing features of claim 1.
  • the cutting table according to the invention ensures a very good support for the material to be cut thanks to the steel band guided and tensioned, which can be penetrated by the high-pressure liquid jet practically unhindered.
  • the cutting device can therefore be used as a processing stage within an assembly line production, since there are no difficulties with the material supply and material transfer.
  • the cutting table consists of two endless chains 3, 4 guided around rollers 1, 2, 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 unrolled from a supply roll 7 and cut by a cutting nozzle 8, as described in the main patent.
  • 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 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 fastened in each case.
  • Tab 14 is provided with two tensioning and clamping devices 16, with which a thin steel strip 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 is preferably 6 mm.
  • the device according to the invention permits automatic disposition of the band-shaped material to be cut 6 rolled from the supply roll 7 onto the rotating cutting table.
  • the steel band 17 stretched between the plates of the distance-secured chains 3, 4 is sufficiently stiff 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.
