Abstract

1,075,992. Punches. G. G. F. SMEETS. Feb. 16, 1965 [April 14, 1964], No. 6641/65. Heading B3W. A punch, punch guide and stripper assembly comprises a punch holder 1 which has an enlarged tubular portion 4, of which part of the wall is removed and an internal groove 5 which receives the flanged head 7 of a punch 6. A stripper spring 2 is held, partially compressed between the part 4 and a clip 3. A single-piece punch-guide and stripper comprises a tubular member with an open end which fits over the part 4 and contacts the stripper spring, a guide bore which fits the body diameter of the punch and a closed end which acts as the stripper plate and has an aperture through which the punch proper 6a projects. In a modification. Fig. 3, the same punch is used but the punch guide and stripper are separate. The stripper comprises a tubular part 14 connected to the stripper plate 12 by bars 13. The punch guide comprises an upper part which fits over the portion 4 and a reduced lower tubular part 15 which has internal splines 16 to receive the bars 13, the punch guide surface is formed by the internal diameter of the splines. In a further modification, Fig. 4 (not shown), the punch is formed with at least one flat on the body diameter 6 and the stripper is made in two parts. One part comprises the plate 12 and the bars 13 and the other part comprises the tubular part 14, which in this embodiment has a floor in which there is a non- circular opening to receive the part of the punch on which the flat is formed. Part of the wall is removed so that the punch may be inserted laterally, and in a predetermined orientation. The tubular part 14 also has external lugs which project through slots in the head of the punch guide and engage a keyway in the machine press.
