Application Of Direct Torque Management To Electric Screw Presses For Rushing Up Torque Response And

We are engaged in manufacturing a range of Screw Presses, which are used to dewater and wash secondary in addition to virgin fiber. Since the flywheel vitality proper earlier than the press is very even, exact forging is realized. There are some machines of this and in addition of similar design that aren’t screw presses in any respect – they do not separate solids from liquids however are as a substitute used to fuse them together.

Ltd.

The alternating-present servo numerical-control motor is vertically mounted on a crossbeam of the framework, the flywheel is pushed by the alternating-present servo numerical-control motor, the screw stem is mounted on the flywheel, the slider is pushed by the screw stem via a screw pair, the balancing cylinder is mounted on the framework and used for raising the back stroke of the slider, and the brake is mounted above the crossbeam of the framework and used for braking the flywheel.

Cnc press is a brand new expertise type of electric screw press ,which were driven by everlasting magnet synchronous servo motor,and include mechanical pats comparable to framework, flywheel, screw nut, the slider, lubricating mechanism, braking mechanism and electric elements resembling servo motor, electric management cabinet, working button station.

AC servo numerical control electrical fly press of the present invention within the backhaul braking procedure, owing to generating regains regenerated power, could be practiced thrift 30%~50% electric braking and ram speed discount course of, servomotor can generate electrical energy and return energy plant, like this, simply can reduce the whole energy consumption of factory.

Shortly earlier than the influence of the upper half of the forging die, secured to the slide 7 upon the forging work-piece lying within the decrease half of the forging die, the traces 31 to the axial piston motor 26 are quick-circuited, as the magnetically managed 4-means valve forty one is moved from its rest place (as shown in FIG.

AC servo numerical management electrical fly press of the present invention, the kind of drive is simple, and upkeep workload may be very little, and labor financial savings and upkeep price are handy to maintenance and restore.Therefore, easy to upkeep.

The advantage of static pressure sort press machine is its static stress screw-nuts and the static strain bearing. variable frequency drive technology keep away from impacting the facility grid and different equipment running. The vacuum pump pumps the air in the barrel, and then detrimental pressure varieties in the barrel.

The press has all function in use, simple in structure, assembly operation and auxiliary tools and its worth is decrease, so it may be extensively utilized in urgent shop, forging shop and die forging shop for equipment manufacturing, etc. Compression is achieved through the use of graduated pitch compression levels, sometimes combined by tapering the diameter of the shaft of the screw in order to power material in opposition to the encircling display screen.

For this function the oil pump 27 is provided with a strain gauge 35 and an actuating drive 37 which is actuated as a operate of stress by way of a control 36 and which within the case of an axial piston pump ideally used in this connection causes the piston axes to pivot in the direction of the drive axis.
