Abstract
A press includes a frame, a flywheel, a motor for driving the flywheel, and a shaft. A clutch is provided which is actuable for engaging the shaft to the flywheel. An eccentric is journaled upon the shaft and rotates therewith. The eccentric rotates in a block which is slidably mounted in a head to permit the block to move laterally within the head. The head is vertically movable in response to vertical movements of the block. The press also includes an upper die which is mounted on the head and a lower die which is resiliently supported upwardly on a base. Movement of the head engages and disengages the upper die and lower die.
Claims31
A press, comprising
- a frame,
- a first die and a base for supporting the first die with respect to the frame,
- a second die and a reciprocally movable head for reciprocally moving the second die with respect to the first die,
- a shaft rotatably mounted within the frame and an eccentric drive means for connecting the shaft to the head,
- a flywheel rotatably mounted to the frame, drive means for rotatably driving the flywheel, a selectively actuable clutch for engaging the flywheel to the shaft, and
- control means for controlling dwell time of the press by the selective actuation of the clutch at a preselected rotation position of the shaft, the control means including means for sensing the position of the shaft and means for actuating the clutch in response to a sensed position of the shaft.
A press, comprising
- a frame,
- a first die and a base for supporting the first die with respect to the frame,
- a second die and a head for reciprocally moving the second die with respect to the first die,
- a shaft rotatably mounted within the frame and an eccentric drive means for connecting the shaft to the head, the eccentric drive means comprising a block received within the head and a disk received within the block, the rotational movement of the disk being translatable by the block into reciprocal movement of the head to bring the first and second die into and out of engagement,
- a flywheel rotatably mounted to the frame, drive means for rotatably driving the flywheel, a selectively actuable clutch for engaging the flywheel to the shaft, and
- control means for controlling dwell time of the press by the selective actuation of the clutch at a preselected rotation position of the shaft, the control means including means for sensing the position of the shaft and means for actuating the clutch in response to a sensed position of the shaft.
A press for forming sheet material blanks into three-dimensional objects, comprising
- a frame,
- a first die and a base for supporting the first die with respect to the frame,
- a second die and a head for reciprocally moving the second die with respect to the first die,
- a shaft rotatably mounted within the frame and an eccentric drive means for connecting the shaft to the head,
- drive means including a clutch for rotatably driving the shaft,
- an entrance conveyor and an exit conveyor, and means for movably connecting one of the entrance and exit conveyors to the frame to permit movement between an operating position and a position which permits access to the eccentric drive means, first die, and second die, and
- control means including means for sensing the position of the shaft and means for actuating the clutch to disengage the shaft in response to a sensed position of the shaft.
