Description
Technical field
The present invention relates to a kind of clutch type screw press that is used for metal material pressure forming processing.
Background technology
Chinese patent 200310105468.9 specifications disclose a kind of clutch type screw press.This forcing press comprises belt pulley, flywheel, slide block, back haul system, clutch, pressing system, depressurized system, hydraulic system and Circuits System.
The depressurized system of this forcing press adopts the electromagnetic hydraulic pressure sensor, and the oil pressure in the hold-down cylinder increases with the increase of technology power.When oil pressure reaches the electromagnet current setting value, the action of electromagnetic hydraulic pressure sensor, and by realization releases such as pilot valve and main valves.During release, many control valves of hydraulic system need successively to open in order, and the unlatching response time is longer, and off-load lags behind, and speed is slower, build-up of pressure machine overload easily, the service life of reducing the forcing press mould.
The slide block backhaul of this forcing press is to be promoted by hydraulic cylinder, is full of pressure oil below the hydraulic cylinder piston.But during the slide block impulse stroke, downward speed is very high, is subjected to the influence of oil cylinder oil extraction process, makes slide block down be subjected to big resistance, has consumed the energy of flywheel, has influenced the hitting power of slide block.
Summary of the invention
The objective of the invention is to provide long fly press of fireballing life-span of a kind of off-load.
The object of the present invention is achieved like this: this forcing press comprises frame, slide block, flywheel and motor, the frame central place is equipped with screw rod, the screw rod bottom is connected with brake gear and slide block, flywheel links to each other with motor by belt, flywheel and clutch are linked in sequence from lower to upper on screw rod top, and clutch is connected with the cylinder by compressed air-driven.
Described clutch is that power plate and friction train are linked in sequence from lower to upper on screw rod top, pressing plate is enclosed within the outside of friction train, and the lead lower end and the flywheel of band spring are fixedly linked, and the lead upper end is movably connected with pressing plate, handle the outside that piece is enclosed within pressing plate, handle piece and link to each other with cylinder.Described power plate comprises disk body, and the disk body center is provided with axis hole, and shaft hole sleeve is on screw rod, and disk body is connected with brake pad and spring, and the brake pad upper end is provided with step, and supporting plate is enclosed within outside the axis hole and between the step and spring of brake pad.Described friction pulley is the star motion structure, and the friction pulley that is connected with the band conical surface by supporting mechanism constitutes, and the conical surface of friction pulley combines with the inclined-plane of pressing plate.
Pressing plate in the clutch can move up and down under the drive of cylinder piston rod and manipulation piece.Do when hitting action, the downward pressing friction piece of this pressing plate combines with the flywheel of rotation, drives the screw rod clockwise direction and rotates slide block down.When pressing plate moved up, the pressing friction wheel utilized frictional force to drive screw rod and counterclockwise rotates, and slide block is up, finishes the backhaul action.
Brake pad floats under supporting plate and spring action, with pressing plate, flywheel the 2-3 mm clearance is arranged, and does not produce the inoperative wearing and tearing, has also avoided the additive decrementation of energy, has reached highly efficient durable and energy-conservation effect.
The present invention utilizes the friction pulley of the band conical surface to realize the conical surface friction transmission, the conical surface of friction pulley is with after the inclined-plane of pressing plate combines, under the friction pulley effect of power in the horizontal direction, the wheel shaft of friction pulley is done moving of horizontal direction in the flat hole, promptly press to screw rod, under the effect of frictional force, screw rod is counterclockwise rotated, realize the backhaul of slide block.This kind structure makes slide block motion up and down not be subjected to any additional friction, and the energy of flywheel can fully be used in the distortion of workpiece, so hitting power is big.
The present invention utilizes compressed air to do the steering maneuver of clutch, and stress-relief process lacks than the link of hydraulic system release, so speed is faster, can realize quick relief, prevents overload.Simple in structure, processing performance is good, makes easily and uses.Force de frappe is big, and cost is low, the efficient height.Can be used for the metal material pressure forming processing of industries such as automobile, machine-building, hardware ﹠ tools.
