Definitions
- Patented March 16, 1-971 3 Sheets-Sheet 5 PUNCIIING DIE It is the purpose of the present invention to provide improvements of known punching dies having a strip steel knife closed to a specific shape and being held on a base plate.
- the invention uses perforated strip steel to which holding angles are fastened which extend into the space surrounded by the configuration of the strip steel knife, for connection to a base or inner plate by further fastening means which whereby a clearance or spacing is provided between the plate and the strip steel knife.
- FIG. 4 is a section similar to FIG. 2 of a further embodiment
- FIG. 5 shows the fastening of a cutting-in knife on the strip steel knife
- FIG. 9 is a section through the strip steel for the embodiment according to FIGS. 7 and 8.
- a strip steel length 1 provided along its full length with perforations in the form of a single or double hole row is bent to a closed or endless configuration corresponding to a pattern, for example, a sleeve pattern.
- perforations holding angles 2 are fastened, e.g. by screws or by riveting, with so-called pop rivets 5 or the like.
- cutting-in knives 3 or other marking tools are fastened to the strip steel knife I, by means of sheet metal holders 3a with screws or rivets 5 (FIG. 5).
- the base or inner plate 27 has a configuration which rests practically without any clearance inside the knife of the die.
- the strip steel knife 21 is provided on its inner or plate facing surface with a groove 22 extending in parallel to its cutting-edge (FIG. 9).
- the gist of the second embodiment of the invention is to ob tain with the same simple and cheap holding means as in the first embodiment an exactly shaped pattern made of relatively thin, but sufficiently resistant material placed directly into a punching die.
- a strip steel knife blade having a plate facing wall of given width and a cutting edge forming a closed configuration corresponding to said pattern, is attached to an inner plate having a given thickness, by means for rigidly securing the knife blade to the plate, the improvement comprising: a groove in said plate facing wall of said knife blade, said groove having such a depth that the groove extends between the plate facing wall of the knife blade and a plane extending through the cutting edge in parallel to said plate facing wall, said groove having a width corresponding substantially to the thickness of said plate, said groove extending in a plane defined by said plate so that the plate extends into the groove.
- said securing means are holding angles comprising a knife facing leg and a plate facing leg, and barbs secured to said plate facing leg for entering into said plate.
