Abstract

The tool has an axially reciprocating rod punch (3). The punch is guided axially by a barrel (1, 4) and centres during the working stroke on a holed matrix. The matrix hole is formed in a separate plate (2) which is set in a recess (9) in the punch counter block. Initially the punch rod (3) is brought down to engage the matrix hole with the matrix plate (2) "floating" in the recess (9). Then liquid cement (10) is poured into the space between the matrix plate (2) and the recess (9). When the cement sets the matrix is fixed in perfectly aligned position. The punch guiding barrel (4) may be formed by moulding a machined plastic sleeve into the barrel housing (1) and onto the punch rod (3).
