Abstract
A stripper plate supporting assembly has a stripper spool unit including a stripper spool and retaining screw for supporting the stripper plate in a die press in a manner that the stripper plate may be removed from a die set without removing the die set from the press. The stripper spool has a shank with at least one spring biased pin in its flat end. At least one opening or socket is provided in the stripper plate for receiving the pin and preventing the stripper spool from turning with the retaining screw.
Claims8
A stripper plate supporting assembly for a die press comprising:
- a stripper spool having a shank, a head and a flat end remote from said head, a drilled and tapped longitudinal hole extending inwardly from said flat end, a bore in the flat end spaced from the drilled and tapped hole, a pin received in said bore is spring biased to normally project a free end of the pin beyond the flat end,
- a die set with a bore having a diameter for close sliding fit with said stripper spool shank and a shoulder for limiting the length of relative travel between said stripper plate and said die set,
- a stripper plate with a bore in axial alignment with said drilled and tapped hole in said stripper spool, an opening or socket spaced from the bore for receipt of the free end of the pin,
- a retaining screw extending through said stripper plate bore and threading into said drilled and tapped hole, said retaining screw coacting with said stripper spool to hold and support said stripper plate in position against said flat end of the stripper spool, said free end of the pin received in the opening or socket in the stripper plate preventing the stripper spool from turning with the retaining screw.

A stripper plate supporting assembly comprising:
- a stripper spool having a shank, a head and a flat end remote from said head, a drilled and tapped longitudinal hole extending inwardly from said flat end, a closed-ended longitudinal bore in the flat end spaced from the drilled and tapped hole, a pin received in said bore is spring biased to normally project a free end of the pin beyond the flat end,
- a die set with a bore having a diameter for close sliding fit with said stripper spool shank and a counterbore in said die set remote from said stripper plate and having a diameter for close sliding fit with said bolt head and a depth greater than the axial length of said bolt head by the length of relative travel between said stripper plate and said die set,
- a stripper plate with a bore in axial alignment with said drilled and tapped hole in said bolt, an opening or socket spaced from the bore for receipt of the free end of the pin,
- a retaining screw extending through said stripper plate bore and threading into said drilled and tapped hole in the stripper spool, said retaining screw coacting with said stripper spool to hold and support said stripper plate in position against said flat end of the stripper bolt, said free end of the pin received in the opening or socket in the stripper plate preventing the stripper spool from turning with the retaining screw.
