Definitions

  • ABSTRACT A punch tool is mounted within a tubular portion of a tool-carrier by means of two separable half-shells which engage over the shank of the tool.
  • the shells are retained within the tool-carrier by means of a pin extending transversely therethrough.
  • the tool-carrier is reciprocable within a bore of a support member, and the pin has a head engaged in an axial groove in the bore.
  • a support having a bore, said bore having a groove, a cylindrical tool-carrier slidable in said bore, said tool carrier including, a tubular portion, said tubular portion having an abutment surface, a punch tool, said punch tool including a shank, two seperable half-shells, Said half-shells engaging over the tool shank and fitting into the tubular portion for engagement with said abutment surface whereby to transmit impact force, the half-shells and the tubular portion having aligned radial holes located beyond the tool shank, and pin means extending through said aligned holes, said pin means including a projecting head, said head being engaged in said groove whereby to guide the toolcarrier in the bore.
  • FIG. I is an axial cross-section of a punch tool mounting arrangement
  • FIG. 2 is a perspective view, to an enlarged scale, showing two tool-mounting shells of the arrangement of FIG. 1.
  • a support in the form of a head plate I or goose-neck of a punching press having at least one cylindrical bore which receives a slidable tool-carrier 3 of cylindrical form.
  • One end portion of the tool-carrier 3 is shaped to receive the head of a ram or other impact-imparting element arranged to actuate same.
  • the tool-carrier 3 has a tubular clamping portion 5.
  • a punch tool 6 clamped within the clamping portion has a shank 7 profiled so as to form at least one axial retention element which may be projecting or hollow.
  • the tool shank 7 is cylindrical and has an annular groove 8 delimited at the opposite side to that of the working portion of the tool, by a flat shoulder or step 9.
  • the tool-carrier 3 also comprises two semicylindrical shells l0 and 11 shaped internally to define patterns 12 and 13 of complementary shape to that of the tool shank 7. Within the patterns, there is provided an annular rib which engages, the groove 8 of the tool shank 7, and the patterns are positioned, without any play, within the tubular clamping portion 5.
  • a pin 14 is inserted through aligned radial holes 15 to 17 in the clamping portion 5 and in the shells l0 and 11.
  • the pin 14 has a projecting head 18 engaged in a groove 19 opening into the bore 2 topermit axial movement of the tool-carrier 3and tool 6 relative to the support 1 whilst preventing rotational movement therebetween.
  • the tool shank 7 and the shell patterns 13 and 14 are not bodies of revolution, the working portion of the tool 6 will be accurately located with respect to the support 1 andvconsequently with respect to the corresponding die. If, as in the embodiment illustrated, the tool shank 7 and the patterns 13 and 1.4 have a shape of a body of revolution, the same result is obtained by means of a projecting peg 20 rigid with the tool shank 7 and engaged in a notch or recess 21 in the shells.
  • annular groove 22 is provided on the internal surface of the clamping portion 5 and surrounds the shells l0 and 11. This groove is in permanent communication with a passage 23 opening in alignment with a jet( not shown) and fed by a lubricant distribution circuit, when the tool-carrier 3 is located in a standby position at the upper end of its stroke.
  • the groove 22 is alsoin communication with at least one longitudinal passage formed by chamfers 24, 25 of the shells 10 and 11. The lubricant distributed thus flows through the. passage 23, the groove 22 and the passage formed by the chambers 24,, 25 until it reaches the cutting area of the tool 6.
  • the arrangement described is applicable tomagazine heads or turrets of punching and/or notching presses preferably of the automatic and programmed type, as well as to punching units.
  • a support having a bore, said bore having a groove a cylindrical tool-carrier slidable in said bore, said toolcarrier including a tubular portion, said tubular portion having an abutment surface,
  • pin means extending through said aligned holes, said -pin means including a projecting head, said head being engaged insaid groove whereby to guide the tool-carrier in the bore.
  • the tool shank has an axial retaining groove, the innermost edge of said groove being defined by a shoulder, and an 4.
  • the tubular portion has an annular groove formed on its inner surface and encircling the shells, said tool-carrier I including,
