Abstract
A new and improved cross-beam press includes a carriage which is mounted for movement along a cross-beam located rearwardly of the bed of the press. A movable press head is suspended from the carriage so as to be above the bed of the press. A control system controls the movement of the press head as the same travels toward and then away from the bed of the press. The control system includes means for adjusting the ultimate approach position of the press head with respect to the bed of the press. As a further feature, the bed of the press can be positioned in two different heightwise positions relative to the movable carriage.
Claims8
A travelling head press comprising:
- a lower platen;
- a cross-beam extending across the width of the lower platen and positioned rearwardly thereof, said cross-beam having a flat front face with an upper rail and a lower rail extending outwardly from the flat front face;
- a carriage mounted on the upper and lower rails extending outwardly from the flat front face of the cross-beam so as to allow slidable movement therealong at a short distance from the front face;
- an upper platen suspended from said carriage;
- and
- means for effecting relative movement between said upper platen and said lower platen so as to effect an operating stroke of said press.
A press having at least two platens wherein relative movement is effected therebetween so as to effect an operating stroke of said press, a stroke control system for adjustably limiting the relative movement between said platens, said stroke control system comprising:
- a limit switch;
- an actuator for said limit switch, said actuator being mounted for movement relative to said limit switch so as to approach said limit switch during the operating stroke of said press;
- means for terminating the relative movement between said platens upon actuation of said limit switch by said actuator;
- means for adjusting the relative positions of said limit switch and said actuator so as to thereby vary the amount of relative movement between said platens;
- and
- means, responsive to the activation of said limit switch, for selectively locking the relative positions of said platens at the end of the operating stroke whereby further adjustment of the relative positions of said limit switch and said actuator may be accomplished.
