Definitions

  • the cost of the raw material also affects the cost of the moulded pieces to a very high percentage that can vary between 50% and 75% of the total cost of production. You can obtain a considerable saving in terms of material costs, optimizing the use of the sheet, so as to minimize the amount of scraps. If it is necessary to manufacture approximately circular parts , if the starting material consists of a strip of metal sheet unwinded from a coil, the proper use of the metal sheet suggests to cut the shape of departure on the strip, not on a single row, but on rows staggered between them ( Fig.1 )
  • the transfer press normally allows you to obtain the moulded piece , with a series of dies. Dies are mounted on the press aligned with the axis of the press itself.Dies are equidistant between them and the distance is called "pitch”. Pieces to be worked are transferred from one die to another, at the same time, after each stroke of the press, by means of an "iron hand " mounted on two longitudinal bars, a bar at each side of the machine.
  • the iron hands during each stroke of the press ram, advance simultaneously one step the parts to be worked on the series of dies .
  • the first die separates the blank from the strip.
  • the blank generally consists of a flat shaped element. This element is transferred to the second die and so on. You typically use four or five dies aligned among them.
  • US3,589,221 discloses a system for cutting strips of scrap metal removing circular sections in a pattern of staggered longitudinal rows.
  • This system is to eliminate the disadvantages of the systems described above, achieving the aim of a substantial reduction in the weight of the sheet scraps .
  • the complete system is defined according to claim 1.
  • the system comprises:
