Abstract

The invention relates to a method of mounting a tool re­ tainer plate (12) for a punch or die tool (16) to a die shoe (14), the retainer plate having bolt holes (18, 20) for receiving bolts therethrough for attaching it to the die shoe, a bore (30) in the plate including a ball lock (48, 50, 52) for receiving the tool, a first dowel pin hole (36) being concentric with the bore and a second dowel pin hole (54) being spaced therefrom along a re­ ference line for locating the bore (30) relative to the die shoe. The method includes the steps of first preparing the die shoe by selecting a location on the die shoe including a point to coin­ cide with the centerline of the bore (30) and selecting a line, corresponding in orientation to the reference line, extending through that point to determine the orientation of the retainer, drilling a first hole (38) in the die shoe coinciding with the said point for receiving the first dowel pin, drilling a second hole (56) in the shoe on the line for receiving the second dowel pin, drill­ ing and tapping mounting holes (22, 24) in the shoe for receiv­ ing the attaching bolts, inserting the first and second dowel pins into their respective holes, placing the retainer plate on the shoe such that the first and second dowel pins engage the cor­ responding dowel pin holes in the plate, and threading the bolts through the mounting holes to secure the plate to the shoe.
