wherein a tool receiving bore ( 142 ) extends into the threaded section of the lower third portion (C) of the elongated fastener device, and a tool receiving bore ( 222 ) extends into the first upper portion (A) of the elongated fastener device, the enable a tool driven rotational engagement with the first thin plate ( 12 ) and the second thicker plate ( 14 ).
2. The elongated fastener device as recited in claim 1 , wherein the upper end of the first upper portion comprises a curvilinear surface ( 206 ) through which the tool receiving bore ( 222 ) extends.
3. The elongated fastener device as recited in claim 1 , wherein the second transition perimeter ( 216 ) of the first strain relief channel ( 214 ) is arranged to lie transversely adjacent the juncture (J) of the first plate ( 12 ) and the second plate ( 14 ) and secure the first thin plate ( 12 ) to the second thicker plate ( 14 ).
4. A die plate and holding plate securement arrangement for a punch press machine assembly, the securement arrangement comprising:
an elongated fastener device ( 200 ) for enabling the securement of a the die plate ( 12 ) and a the holding plate ( 14 ) of a punch press assembly, the elongated device ( 200 ) consisting of three portions of generally equal length, a proximal or first upper portion (A), a middle portion (B) and a lower portion (C);
wherein the first upper portion (A) of the elongated fastener device ( 200 ) comprises a smooth conical side surface ( 208 ), which is tapered at angle (T) of between 7° to 14° with respect to a longitudinal axis (L) of the elongated device ( 200 ), for smoothly compressing a corresponding conically shaped bore ( 40 ) in the die plate ( 12 ), the smooth conical surface having a lower end ending at a first transition perimeter ( 210 ) of a first strain relief channel ( 214 );
wherein the middle portion (B) of the elongated fastener device ( 200 ) consists of the first strain relief channel ( 214 ), a second transition perimeter ( 216 ) of smaller diameter than the first transition perimeter ( 212 ), the middle portion (B) extending a length along the longitudinal axis is cylindrically shaped and has a diameter equal to the diameter of the first transition perimeter of the first strain relief channel and the second transition perimeter extends from a juncture defined by an abutting arrangement of the die plate and the holding plate and into a bore of the holding plate ( 14 ), the middle portion (B) of the elongated fastener device distally ending at a first transition perimeter ( 238 ) of a second strain relief channel ( 232 ); and
wherein the lower portion (C) of the elongated fastener device ( 200 ) consists of the second strain relief channel ( 232 ) defined by the first transition perimeter ( 238 ) and the second strain relief channel ( 232 ) with a threaded section ( 220 ) extending distally to a distalmost end ( 240 ) of the elongated fastener device; and
wherein a tool receiving bore ( 142 ) extends into the threaded section of the distalmost end ( 240 ) of the lower portion (C) of the elongated fastener device ( 200 ), and a tool receiving bore ( 222 ) extends into the first upper portion (A) of the elongated fastener device ( 200 ), to enable adjustable rotational engagement within a set of die and holding plates ( 12 and 14 ) being adjustably joined, from either or both sides thereof.
