Clutch brakes for mechanical presses

Abstract

The invention provides a clutch brake device used for a mechanical press. The clutch brake device used for the mechanical press at least comprises an air inlet, an air chamber, a piston, a clutch body, a clutch wheel hub, brake plates and a brake friction disk. In a non-braking state, the brake plates are separated from the fourth kind of plates on the brake friction disk, the fourth kind of plates are separated from the second kind of plates, the first kind of plates are combined with the third kind of plates, and therefore the clutch body is combined with the clutch wheel hub. In a braking state, the brake plates tightly clamp the fourth kind of plates, the fourth kind of plates clamp and push the second kind of plates, and the first kind of plates are separated from the third kind of plates accordingly. The piston is located inside the air chamber, the movement of the piston in the axial direction is achieved according to the ventilation conditions of the air inlet, then, the brake plates are driven to move in the axial direction through the movement of the piston in the axial direction, and therefore conversion between the non-braking state and the braking state is achieved.

Description

technical field [0001] The invention relates to a brake, in particular to a clutch brake device for a mechanical press. Background technique [0002] Dry clutch refers to the use of air to cool the clutch. In use, it is required that the clutch can be easily and freely engaged and separated from the power, and the clutch should not be overheated when working in a short-term half-clutch state. Because the dry clutch has no oil resistance, generally speaking, the bite response is faster and the bite force is larger. Also because there is no cooling of the oil, the general dry clutch will use the exposed method to dissipate heat. [0003] Wet clutches are cooled by oil. The cooling oil does not protect the friction plates, but makes the power transmission smooth and soft. Working in half-clutch state. It is mostly used in automatic transmissions, such as automatic manual transmissions that are commonly used now. A plurality of steel plates and friction plates are pressed b...
