Abstract

1436745 Nibblers TRUMPF MASCHINEN AG 12 June 1973 [13 June 1972] 27912/73 Heading B3W A nibbling or like punching machine coinprises a die 3 and a reciprocable punch 2, the die or a holder therefor being connected to a drive head 4 of the punch by an elongated support member 5 positioned directly adjacent the punch in the head 4 and in a gap between the head and the die when the punch is carrying out a punching stroke, the element and the punch then having a circular cross-section in the gap. As shown, Fig. 1, the lower portion of the member 5 is of circular cross-section and is located in a bore 7 of the die by a pin 8. The working end 24 of the punch 2 is a little more than a semi-annulus and with the member 5 forms a circular cross-section. At the upper end of the member 5 is a semi-annular portion 14 located on a shoulder 15 in the drive head 4 by means of a sleeve 16 which also centres the punch. The lower portion 17 of the sleeve 16, the punch 2, the member 5 and the portion 14 together form a circular cross-section. The sleeve 16 is retained in the head 4 by a pin 18. The punch is screwed to a connecting rod (not shown) for reciprocation by an electric motor. In an alternative embodiment, Fig. 3 (not shown), the sleeve and the support member are integral and the crosssection of the working end of the punch is semicircular plus triangular extensions to give the working end an arcuate periphery extending over more than 180 degrees.
