Abstract
The invention discloses a clutch braking device for a mechanical press. The device comprises a clutch body, a clutch friction block, a brake friction disc, a brake plate, a cylinder, a piston, pull rods and springs; when the press is normally driven to work, the cylinder introduces air, the cylinder and the clutch body clamp the clutch friction block to form a whole, and power output is realized by drive of a flywheel; when braking is required, the cylinder exhausts the air, the springs push the cylinder to leave the clutch friction block, and the springs drive the brake plate through the pull rods to approach and clamp the brake friction disc, so that the clutch friction block is separated from the clutch body, the input of power is cut off, and the brake plate and the clutch body clamp the brake friction disc to form a whole; and because the brake friction disc is fixedly connected with a machine body, the braking function of a clutch can be realized. The clutch braking device has the advantages of large torque, low inertia, convenience in installation and adjustment and high heat dissipation, and can be applied to medium (300 to 1,000 tons) and high-speed presses.
