  • the movement may be effected in any of a number of well-known ways, for example by a numerically controlled system or by preprogramming the movements via a plugboard.
  • the means consist of a punching jig with at least one aperture which corresponds to and is coincident with a predetermined position and that the aperture or the apertures can engage with a die whereupon the material may be punched by a punch coacting with the die.

  • Plateaus such as 20 are rigidly affixed to the opposite sides of the dieblock 18 to support the punching jig 16 with its respective guide plate 17 carrying the component 15 during the punching operations.
  • the punching jig 16 with component 15 and guide plate 17 are located in the first punching position and in which position the six holes C" of the same diameter are punched (the term first punching position as used here defines the first of the seven positions along the common die-block at which punching is to take place).

  • the color of the widest of the three bands denoting the diameter of the punch in tens of millimeters, the next widest denoting the diameter of the punch in whole millimeters and the narrowest band denoting the diameter of the punch in tenths of a millimeter.
  • FIG. 12 shows the widths of the bands of color on a stripper and which bands are designated 28, 29 and 30 respectively.
  • Such a color code may be as follows:
  • the diameter of a hole in a die is greater than the diameter of a corresponding punch by 5 percent of the material thickness to be punched (such a clearance may vary for particular classes of accuracy required in the final hole diameter and the material to be punched).
  • Dies may be color coded to indicate their diameters with clearance by providing four indentations in the upper surface of ever-decreasing diameter.
  • the sizes of such indentations in a die 12 are shown in FIG. 13, the largest to the smallest indicated by the reference numerals 32, 33, 34 and 35.
  • a punch press such as illustrated in FIG. 14 and designated by the reference numeral 36 may have a frame such as 37 fitted and from the horizontal member 38 of which two well-known types of balancer 39 are fitted.
  • These balancers house each a cable such as 40 which by spring means is held in a wound-up condition within the casing of the balancer.
  • the tension with which the cable may be maintained in the wound-up condition may be adjusted by a key 41.
  • These balancers have cable tensions that can be adjusted between wide limits.
  • the tension of certain types can be adjusted so that a pull of anywhere between I and kilos is required (according to the adjustment) to unreel the cable out of the casing of the balancer.
  • This tension can be used to counterbalance the weight of the punching jig 3, the component l and the guide plate 7.
  • Two hooks 42 are affixed to the free ends of the cables and these are arranged to engage in holes drilled in the handles 4 of the punching jig 3.
  • the angles which the cables make with respect to the casings of the balancers 39 and the punching jig 3 are such that irrespective of the position of the punching jig 3 with respect to the punch 8 and its stripper 11 these cables are free from the possibility of fouling the punch press.
  • a multiposition punching jig is employed such that with a component accommodated in the punching jig in one of the positions certain holes may be punched in the component via apertures in the punching jig which do not break through into each other, and such that when the component is accommodated in another position in the jig other holes which are closely spaced to the first punched holes may be punched via apertures which also do not break through into each other.
  • FIG. A there is shown a component 60 having a large hole 61 encompassed by four closely spaced smaller holes 62.
  • FIG. 158 there is shown a part ofa punching jig 63 with four apertures 64 for the punching of the four previously mentioned small holes, which break through into a center aperture 65 for the punching of the previously mentioned large hole 61. It will be seen that sufficient peripheral engagement of the large center hole with a corresponding die will obtain, but in the case of the four apertures 64 which break through" to the center aperture 65 there may not be sufficient peripheral engagement with a corresponding die and thus the possibility exists that dimensional inaccuracies between the centers of holes will result through misalignment between apertures in the punching jig and corresponding dies.
  • FIG. 15C there is shown a two-position punching jig 66 with a component 60 in each half.
  • the large hole 61 in the component may be punched when the component is accommodated in the left-hand half of the punching jig and the jig illustrated at FIG. ISD is utilized, and the component is punched with the four smaller holes 62 when it is accommodated in the right-hand half of the punching and the jig illustrated at FIG. 15E is utilized.
  • punching jigs with more than two positions can be employed when necessary in view of very closely spaced holes to be punched in a component.
  • the periphery of the extending portion of the die is either chamfered or radiused a certain amount of misalignment, between the die and an aperture, the misalignment will be taken up through the action ofthe die, in its vertical movement upward, engaging the peripheral edge of an aperture in the punching jig so that it is forced laterally into alignment. It is therefore proposed that the die should be raised just prior to effecting the punching operation and that punching is inhibited until there is full and proper engagement between the aperture in the punching jig and the die.
  • FIG. 16 A punching jig 98 with a component 99 to be punched and a guide plate 100 rest on the bed 73 of a press.
  • the misalignment of the die 67 and the aperture 101 is indicated with M.
  • the bed contains two pistons 91 and 92 which both extend above the upper surface 74 of the bed under the action of a spring and which can be depressed under the action of the weight of the punching jig, the component and the guide plate. In the depressed situation each piston closes a switch. Moreover, the die closes a third switch in its upper position.
  • the punching press is arranged in such a way that only when the three switches are closed can a punching operation be carried out.
  • FIG. 17 shows the situation whereby the punching jig with its contents is lifted by the die. So in this situation it is impossible to carry out the punching operation.
  • Certain components may have several groups of holes.
  • a group of holes in a component constitutes a punching position therein and by utilizing the methods described herein and adapted tools, groups of holes in a number of punching positions can be punched consecutively.
  • FIG. 18 shows a component 1 12 having six groups of holes. These holes, total three per group, are designated by the reference numbers 109, and 111.
  • the component 112 is 3 meters long and 30 centimeters wide and is of 3-millimeter mild steel.
  • the holes 109, 110 and 111 are of 6, l2 and 18 millimeters diameter respectively.
