Description

A kind of structure of clutch brake for high-speed press

Technical field

The utility model relates to the structure of a kind of structure of clutch-brake, particularly a kind of clutch brake for high-speed press, belongs to the metal forming machinery technical field.

Background technology

Along with the development of forging technology and the requirement of punching production, the operating rate of forcing press is more and more high, and along with the raising of forcing press operating rate, the structure of existing forcing press clutch-brake is incompatibility high-speed blanking press performance demands more and more also.This main cause is: existing clutch-brake all is to adopt air operated friction clutch, this class clutch-brake not only needs pneumatic plant, simultaneously, because clutch-brake modular construction complexity, the volumetric spaces of whole parts is bigger, its rotary inertia is also bigger when high-speed motion, this just needs to consume more energy, in addition, because the separation of clutch is to carry out under the control of mechanical system with combining, and the speed of mechanical movement is difficult to improve further under certain conditions, so, this clutch-brake not only has complex structure, the defective that energy consumption is big especially can not adapt to the performance requirement of high-speed blanking press.

Summary of the invention

The purpose of this utility model is: the structure that a kind of clutch brake for high-speed press is provided, that this structure not only has is simple in structure, energy consumes less characteristics, especially because its parts are less, whole spatial volume is less, total quality is less, it is not in conjunction with relying on traditional mechanical system with separating, thus its transmission inertia is less, the combination of clutch with separate reliable rapidly, steadily; The performance requirement of suitable especially high-speed blanking press.

The utility model realization technical scheme that above-mentioned purpose adopted is achieved in that a kind of structure of clutch brake for high-speed press, and it is made up of flywheel, coil, driving-disc, key, bent axle, nut, conducting ring, dead ring, conductive electrode, magnetic, bearing.Described flywheel is to be installed on the cylindrical of driving-disc hollow shaft by bearing, and driving-disc is installed in an end of bent axle by the hollow shaft that is connected as a single entity with it, and by key itself and bent axle is fixed; The one side that described driving-disc is relative with flywheel has a cannelure, and coil is installed in the groove; The space of forming sealing between one side that driving-disc is relative with flywheel and the flywheel, and in the space filling magnetic, in order to make driving-disc and flywheel fixed-site when moving, on the cylindrical of the step of bent axle one end, make external screw thread is arranged, the nut of on externally threaded, screwing on, with driving-disc and flywheel be fixed on bent axle above, end at bent axle, two dead rings are installed respectively, two conducting rings are installed respectively on the cylindrical of dead ring, two end connectors of coil link to each other with conducting ring respectively, and a conductive electrode is installed respectively on the periphery of conducting ring, and and conducting ring between form Elastic Contact.

The utility model is like this work: when the two poles of the earth of dc source are connected on two respectively above the conductive electrode time, then electric current forms the loop by two conductive electrode, conducting ring, coil, because the effect of electromagnetic induction, the coil of energising forms closed magnetic circuit, wherein the strongest around coil, so, magnetic gather immediately under the electromagnetic action of coil coil near, flywheel and driving-disc are combined, so, flywheel drives driving-disc, and driving-disc drives bent axle by key and rotates, and forcing press is started working; When coil blackout, then magnetic is in state freely, and flywheel separates with driving-disc, and forcing press is not worked.

Beneficial effect: the utility model is owing to adopt separation that the coil drive magnetic of energising realizes clutch and combine, so structure of this clutch brake for high-speed press, not only have characteristics simple in structure, that energy consumption is less, especially because its parts are less, whole spatial volume is less, total quality is less, and it is not in conjunction with relying on traditional mechanical system with separating, thus its transmission inertia is less, the combination of clutch with separate reliable rapidly, steadily; The performance requirement of suitable especially high-speed blanking press.
