Abstract
A control system for a press having a clutch and a brake includes a clutch control valve and a brake control valve. The clutch control valve operates the clutch by supplying pressurized air to the clutch. The brake control valve operates the brake by supplying pressurized hydraulic fluid to the brake. The brake control valve is activated by pressurized fluid from the clutch control valve in order to insure simultaneous release of the brake with engagement of the clutch as well as simultaneous application of the brake with disengagement of the clutch.
Claims17
A press comprising:
- a fixed member;
- a crankshaft rotatably disposed with respect to said fixed member;
- a flywheel rotatably disposed with respect to said fixed member;
- a brake disposed between said crankshaft and said fixed member;
- a clutch disposed between said crankshaft and said flywheel;
- and
- a control system for said press, said control system comprising:
- a first source of pressurized fluid to operate said clutch;
- a first control valve disposed between said first source of pressurized fluid and said clutch;
- a second source of pressurized fluid to operate said brake, said second source of pressurized fluid being independent from said first source of pressurized fluid;
- and
- a second control valve disposed between said second source of pressurized fluid and said brake, said second control valve being in communication with said first control valve.
A control system for a clutch and a brake, said control system comprising:
- a first source of pressurized fluid adapted to be in communication with said clutch;
- a first control valve in communication with said first source of pressurized fluid and adapted to be in communication with said clutch;
- a second source of pressurized fluid adapted to be in communication with said brake, said second source of pressurized fluid being independent from said first source of pressurized fluid;
- and
- a second control valve in communication with said second source of pressurized fluid adapted to be in communication with and said brake, said second control valve being in communication with said first control valve.
