Abstract
A compensating bolster and die holder combination for use with the bed of a press brake to provide vertical adjustment and compensating camber to the die holder supported thereby. The die holder is vertically moveable in an open channel of an underlying elongated bolster fitted to the bed of the press; with plural wedge members, moveable transversely of the die holder, serving to adjustably position and support the latter. Each wedge member has joined thereto an indicator pin extending through one side of the bolster which operates to visually indicate the adjusted position of its wedge member; while the several indicator pins cooperate to show the relative adjusted positions of the several wedge members and the consequential adjusted elevation of the die and die holder.
Claims11
A compensating die holder for use with a press brake, comprising:
- a bolster block having means for attachment to the bed of the press and comprising an elongated rigid body of substantially U-shaped cross-section formed with an elongated channel opening inwardly of one face thereof;
- said channel being laterally confined between parallel arm portions of said body;
- an elongated die holder mounted in said channel for limited vertical movement guided by opposing walls of said arm portions;
- wedge means mounted between the bottom of said channel and said die holder for limited movement transversely of said channel;
- such movement of said wedge means effecting vertical movement of said holder;
- bolt means extending transversely through said body and wedge means and having threading engagement only with the latter whereby to adjustably move said wedge means transversely of said channel in response to rotation of said bolts means;
- and indicator means, independent from said bolt means, which are responsive to movement of said wedge means and operable to visually indicate, externally of said body the transverse position of said wedge means in said channel.
A compensating die holder for use with press brakes, comprising:
- elongated bolster means attachable to the press bed and formed with an elongated open channel recessed in the upper side thereof, die holder means mounted in said channel for vertical movement, wedge means mounted in said channel beneath said holder means for movement between limits transversely of said channel to effect vertical movement of said holder means, adjustment means coupled to said wedge means and operable for adjustably moving said wedge means transversely of said channel, and indicator means independent from said adjustment means and extending from said wedge means to the outside of said bolster means;
- said indicator means being attached to and moveable responsively with said wedge means and presenting a portion thereof which is visible outside of said bolster means for visually indicating the position of said wedge means in said channel.
In a compensating die holder for use with a press brake having elongated bolster means attachable to the press bed for supporting die holder means moveable in an elongated channel of the bolster means, and wedge means moveable in the channel for adjustably actuating the die holder, the improvement comprising:
- indicator means extending between the wedge means and an outside face of the bolster means for indicating the position of the wedge means in said channel;
- said indicator means being freely slideably moveable within the bolster means and responsive to the movement of said wedge means and having a visible portion coplanar with or projecting from said outside face for indicating the position of the wedge means in said channel.
