Abstract
The utility model discloses a press machine cam self-regulation mechanism in the technical field of forcing presses, which comprises an upper and lower supporting plates. Four guiding chain wheels are arranged between the upper and lower supporting plates in a rectangular arrangement, the upper end of the lower supporting plate is provided with a fixed plate on which a driving screw is axially fixed along the center of the lower supporting plate, and the upper end of the driving screw is connected with the output shaft of an electrical motor. A screw nut fixed on one end of a slide block is engaged on the driving screw. The upper supporting plate is provided with a slide groove matching with the slide block, and the upper and the lower ends of the slide block are respectively provided with an adjusting chain wheel. One side of the upper supporting plate is provided with a cam controller chain wheel, and the other end of the upper supporting plate is provided with a crankshaft chain wheel. The chain wheels are at grade, and a chain is winded among the chain wheels in a hollow cross-shaped way. The cam self-regulation mechanism can realize the self-regulation of a press machine eccentric sleeve, has the advantages of time conservation, labor conservation and high regulation precision, and can be applied to a forcing press with an eccentric sleeve sheathed on a crankshaft and the function of travel regulation.
Description
Technical field
The utility model relates to a kind of control device of forcing press cam, belongs to the press technologies field.
Background technology
In the prior art, a kind of forcing press that has cam controller is arranged, be socketed with an eccentric bushing on the crank of its press crankshaft, by regulating the position of bent axle and eccentric bushing, to change the stroke of press ram, described cam controller comprises cam, camshaft and sprocket wheel, cam and sprocket wheel are fixed on the camshaft, also be fixed with sprocket wheel on the bent axle on the forcing press, sprocket wheel on the bent axle is directly linked to each other by chain with sprocket wheel on the camshaft, the cam that sprocket wheel on the bent axle drives on the cam controller rotates, cam is connected with output device, cam position is used for the power taking signal, through the position of actuating mechanism controls crankshaft operation top dead-centre and the change of stroke can change bent axle and the total eccentric relative position with respect to the cam cam ring of eccentric wheel, requires the relative position of cam and bent axle corresponding one by one.Its weak point is: the cam set in the cam is regulated to be needed manually to carry out one by one, and its operation easier is big, can not realize automation control.
The utility model content
The purpose of this utility model provides the automatic governor motion of a kind of forcing press cam, can realize the automatic adjusting of eccentric bushing position when making it be applied on the forcing press.
The purpose of this utility model is achieved in that the automatic governor motion of forcing press cam, comprise the upper backup pad and the lower supporting plate that are arranged in parallel, be provided with four jockey sprockets between upper backup pad and the lower supporting plate, the rectangular Si Jiaochu that is fixed in upper backup pad of the rotating shaft of jockey sprocket, the upper end of lower supporting plate is provided with the fixed head perpendicular to upper backup pad, the central shaft of fixed head upper edge lower supporting plate is to being fixed with screw mandrel, the screw mandrel upper end is connected with the output shaft of motor, be engaged with a nut on the screw mandrel, described nut is fixed on the end with the slide block of screw mandrel axially parallel, upper backup pad is provided with chute, described slide block is equipped with in chute, the top and bottom of slide block respectively are provided with one and regulate sprocket wheel, upper backup pad one side be provided with one with the cam controller sprocket wheel of cam controller interlock, the upper backup pad opposite side be provided with one with the crankshaft sprocket of bent axle interlock, described each sprocket wheel is in the same plane, by chain phase interlock, described chain is walked around each sprocket wheel and is linked to be hollow " a ten " font between each sprocket wheel.
When work, when motor keeps motionless, cam controller can make cam and bent axle be in a relatively-stationary angle, when motor rotated, screw mandrel promoted slide block through nut and moves, and drives corresponding sprocket rotation, the switched in opposite of crankshaft sprocket and cam controller sprocket wheel, make to relatively rotate between eccentric bushing and the bent axle, during to correct position, the motor stall.The utility model can be realized the automatic adjusting of press off-centering cover position, and changing the upper dead center position of slide block, its adjusting saves time, laborsaving, the degree of regulation height.Relevant position at cam controller, bent axle or eccentric bushing can be provided with inductor, by machinery and electric control in combination, makes the operator know the position of slide block top dead-centre more intuitively, thus better control operation.The utility model can be applicable to be socketed with on the bent axle on the forcing press with stroke adjustment function of eccentric bushing.
