Abstract
The invention discloses a structure of a clutch brake for a high-speed press. A fly wheel is arranged on the excircle of a hollow shaft of a drive plate through a bearing; the drive plate and the hollow shaft connected with the drive plate into a whole are arranged at one end of a crankshaft and are fixed with the crankshaft through a key; an annular groove is arranged on one surface of the drive plate, which is opposite to the fly wheel; and a coil is arranged in the groove. The one surface of the drive plate, which is opposite to the fly wheel, and the fly wheel form a closed space; a proper amount of magnetic powder is filled in the closed space; an external thread is formed on the excircle of a step at one end of the crankshaft for positioning the drive plate with the fly wheel during movement; a nut is screwed on the external thread for fixing the drive plate and the fly wheel on the crankshaft; two insulating rings are respectively arranged at one end of the crankshaft; two conductive rings are respectively arranged on the excircles of the insulating rings; joints at two ends of the coil are respectively connected with the conductive rings; one conductive electrode is arranged on the excircle surface of each conductive ring; and the conductive electrodes are elastically contacted with the conductive rings.
Description
Technical field
The present invention relates to the structure of a kind of structure of clutch-brake, particularly a kind of clutch brake for high-speed press, belong 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.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 objective of the invention is to: the structure that a kind of clutch brake for high-speed press is provided, the 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.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of structure of clutch brake for high-speed press, it is made up of flywheel, coil, driving-disc, key, bent axle, nut, conducting ring, dead ring, conductive electrode, magnetic, bearing.Described flywheel is installed in by bearing on the cylindrical of hollow shaft of driving-disc, 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 groove that has annular of the one side that described driving-disc is relative with flywheel is equipped with coil in the groove.The space of forming sealing between one side that driving-disc is relative with flywheel and the flywheel, and during the magnetic of filling right quantity, in order to make driving-disc and flywheel fixed-site when moving, producing external screw thread on the cylindrical on the step of one end of bent axle, the nut of screwing on above the external screw thread, with driving-disc and flywheel be fixed on bent axle above, end at bent axle, two dead rings are installed respectively, on the cylindrical of dead ring, install two conducting rings are installed respectively, 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.
Operation principle of the present invention is, 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, 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 present invention 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.
