Definitions

  • the invention relates to a punching apparatus for flat metal plates.
  • a first drawback is that the high use of lubricating fluid tends to inconveniently soil the components of the apparatuses during machining.
  • a second drawback is related to the cleaning of known-type punching apparatuses which is very time-consuming and difficult to be performed optimally.
  • the task of the present invention is to develop a punching apparatus for flat metal plates capable of overcoming the aforementioned drawbacks and limitations of the prior art.
  • an object of the invention is to develop a punching apparatus with which the use of lubricating fluid can be controlled by limiting dripping thereof onto the components being machined.
  • Another object of the invention is to develop a punching apparatus with shorter cleaning times than similar apparatuses of the known type.
  • an object of the invention is to develop a punching apparatus with a more effective cleaning procedure than similar known apparatuses.
  • Another task of the invention is to develop a metal sheet stamping plant comprising a similar apparatus.
  • a punching apparatus is indicated as a whole by number 1.
  • This punching apparatus 1 well visible in Figure 2 , comprises everything indicated in the following list.
  • Also covered by the invention is a metal sheet stamping plant 100 comprising a punching apparatus 1 as described above.
  • such a plant 100 comprises at least one punching station 101 in turn comprising a press set up with a punching apparatus 1 as described above.
  • the plant 100 also comprises at least one stamping station 102 configured to stamp a metal sheet.
  • Such at least one punching station 101 and such at least one stamping station 102 are clearly visible in Figure 1 .
  • the plant 100 also comprises at least one cleaning and drying station 103 for a machined metal sheet.
  • This cleaning and drying station 103 is represented in Figures 1 and 11 and in turn comprises:
  • the plant 100 comprises at least one manipulator robot 105 for the transfer of metal sheets between several contiguous stations, as clearly represented in Figure 1 .
  • first manipulator robot 105 for transferring metal sheets from the punching station 101 to the stamping station 102.
  • the invention has developed a punching apparatus that advantageously limits the dripping of the lubricating fluid onto a flat metal plate being machined compared to known-type punching apparatuses.
  • the invention has developed a punching apparatus whose cleaning takes place very quickly if compared to similar apparatuses of the known type that have to be cleaned manually by an operator.
  • the invention has developed a punching apparatus whose cleaning operation is more effective than similar apparatuses of the known type because the forced passage of a pressurised fluid reaches spots that cannot be accessed by an operator.
  • the invention has developed a metal sheet stamping plant comprising such a punching apparatus.
