Novel brake mechanism of rigid clutch press

Abstract

The invention discloses a novel brake mechanism of a rigid clutch press. From inside to outside, a brake wheel and a cam are sequentially arranged and fixed on the upper surface of a crankshaft by a bolt in a way that the positions of protruding arcs correspond to the positions of upper and lower dead points of the crankshaft. A lever is fixedly arranged on the upper surface of a machine body by a pin shaft in a way that the lever is ensured to flexibly rotate about the pin shaft. A roller is fixedly arranged at a proper position on the middle part of the lever by an accurate method. A friction belt is riveted on the upper surface of a brake belt by a rivet. One end of the brake belt is hinged with the pin shaft, and the other end of the brake belt is fixed with a tensioning pull rod by a proper method. The tensioning pull rod passes through a through hole on a lever body, and is sleeved with a spring which is properly pressed by a nut.

Description

Technical field [0001] The invention relates to a rigid clutch brake mechanism, in particular to a brake mechanism of a novel rigid clutch press. It belongs to the technical field of forging machinery. Background technique [0002] In order to reduce the impact and vibration of the press during operation, as well as the adverse effects of impact and vibration on the operating safety and the service life of the press, at the same time, it is also for the press to stop the crankshaft accurately during a single operation. At the dead center position, a mechanical cam brake is designed and installed in the rigid clutch press. [0003] It is currently known that in the structure of the cam brake of a rigid clutch press, the cam is an Archimedes curve, or other forms of curves that vary in the circumferential direction of the cam. Regardless of the cam curve form, in a rotation cycle of the crankshaft, the brake always brakes the rotation movement of the crankshaft. In fact, in a work...

Problems solved by technology

[0004] The object of the present invention is to: provide a kind of braking mechanism of novel rigid clutch press, the braking mechanism of this rigid clutch press can produce reasonable braking in the appropriate position in the whole working stroke of press crankshaft, namely this A braking mechanism of a rigid clutch press, in a complete working stroke of the crankshaft, only produces braking at the positions of the upper dead center and the lower dead center, and in the stroke other than the upper and lower dead centers, the brake is in a non-braking state , overcome the unreasonable state caused by the braking mechanism of the existing rigid clutch press because it is in the braking state in the full stroke position, and overcome the large motor load and energy caused by the unreasonable braking state Defects of high consumption, easy damage of braking mechanism and low lifespan
