  • This disclosure relates to a die tool pack assembly wherein improved and conveniently arranged means are provided for adjustably locking and aligning a die element in the assembly with other elements of the assembly.
  • This invention relates to a die tool pack assembly which can be used in the manufacture of hollow cup-shaped articles, such as cup-shaped containers. More particularly, it is concerned with providing an improved die tool pack assembly wherein the various die elements are at least partially open to visual inspection, are readily accessible for servicing and lubrication and wherein improved means are provided for aligning and holding individual die elements of the assembly in alignment with each other and with a cooperating forming ram during use of the assembly.
  • FIG. 1 is a perspective view of a typical housing for a forming ram with which the die tool pack assembly of the instant invention can be used and wherein the housing is provided with appropriate means for affixing the tool pack assembly to the housing, the ram being shown in dotted lines and with the die tool pack assembly removed;
  • FIG. 2 is a side elevational view of the end portion of the housing with the die tool pack assembly of the instant invention mounted therein when viewed generally along the line 22 of FIG. 1 and with parts removed for the sake of clarity;
  • FIG. 3 is a view generally taken along the line 33 of FIG. 1 with the tool pack assembly of FIG. 2 being added;
  • FIG. 4 is a cross-sectional view of the die tool pack assembly when generally taken along the line 44 of FIG. 2;

  • the forward end 15 of the housing 14 is bifurcated so as to be provided with upper and lower mounting segments or holding arms 16 and 17.
  • the die tool pack assembly 10 is suspended between these arms in a novel fashion which will now be described.
  • the fork arms 16 and 17 are cut on a bias in such a fashion that they provide a slot 18 which advantageously projects at an inclined angle with respect both to a vertical as well as a horizontal plane.
  • the die tool pack assembly 10 is mounted within this slot 18 and is anchored therein by being afiixed to the arms 16 and 17.
  • the die tool pack assembly 10 includes a series of die holder members 20 and 22. As indicated particularly in FIG. 2, die holder member 20 approximates a reverse-C in one planar view whereby it is provided with a central recess or open portion 21 open to the atmosphere, while in another planar view it is generally rectangular in configuration. Recess 21 in effect extends across element 20 and constitutes an elongated slot open at both ends.
  • the slot 21 is defined by partially flat and partially curved surface segments 21a, 21b and 21c.
  • Lower surface segment 21b as viewed in FIG. 2 is intersected by the flat surface 23 and upper surface segment 21b is intersected by the surface 25.

  • the adjustable shoes 35 serve a dual function in that they first act as suitable stop elements which prevent the dies A, B and C from dropping out of the tool pack. Secondly, they provide a simple yet convenient means for controlling and centering the axes of the several dies with respect both at each other and the ram. Adjustment of the lower shoe 35 by engagement of the tool end 38' of locking bolt 38 thereof with a suitable tool and a subsequent turning of the screw adjust a given die element in one direction, while engagement of the tool end 38 of the bolt 38 for the upper shoe 35 with a suitable tool and a subsequent turning of the screw adjust a given die element in another direction.
  • an arm is appropriately pivoted at the pivot point 51 to an end of a die element holder 20 or 22 as the case may be.
  • This locking arm is provided with a shoulder 52 which is adapted to tangentially contact a die ring such as die ring 32.
  • the arm can be held in place as indicated in FIG. 4 by means of the hand operated spring biased and locking screw mechanism 54.
