Veichi AC10 0-YK is a special AC servo contro VFD inverter for electric screw press machine, integrating with variable frequency drive , brake resistor, low voltage electric elements and logic control unit hot forging press manufacturers. working life langer than friction press as a result of the die not bear additional strain.
So as to achieve the above object, AC servo numerical management electric fly press of the current invention includes frame; The vertical AC servo numerical control electric machine that’s installed on the housiung separator; Flywheel by AC servo numerical control electric machine drives is put in in the screw rod on the flywheel, by the slide block of screw rod by means of the screw pair driving; Be put in in the compensating cylinder that’s used to promote the slide block backhaul on the frame, be put in in the brake that the housiung separator high is used to brake flywheel.
Screw press is a major forging tools, its most important benefit is actual vitality control which ensures high course of reliability and repeatability, furthermore, utilizing low pace giant torque motor directly driving the press can take away the clutch, gear, belt, et al driving device, so that the ability consumption might be lowered successfully.
Rod of diameter eighty mm and size 900 mm, which was machine on their lathe at a lowering screw pitch and reducing screw depth. They’re gradual transferring compared with mechanical and screw presses, and squeeze somewhat than impression the workpiece. 7. Electrical screw press has no lower lifeless level, it is easy to alter the die without adjusting the height of the die.
Dynamic mechanical and mathematical fashions for screw press and plastic-working processes of die forging and coining were developed, verified with experimental observations and used for evaluation of screw press dynamics. No consumable parts due to no friction driven system (On the machine which makes use of servomotor typically use, connecting belt between motor and flywheel wears out however its life lasts for several years and is inexpensive to procure.
AC servo numerical management electric fly press of the current invention; Evaluate with friction screw press; Intermediate gearings resembling no frictional disk, transverse axis promptly don’t need intermediate drive, and driving-chain is brief; Do not need the friction band consumable accessory on the friction screw press yet, would not have frictional dissipation and put on downside in the frictional drive.Compare with hydraulic screw press, don’t need Hydraulically Operated Tools complicated, that have comparatively high expectations, don’t have the hydraulic fluid leak contaminated setting and the hydraulic fault problem occurs.Due to this fact, the present invention is easy in construction, and components are few, and driving-chain is short, and the components loss is little, and is easy to fabricate, and cost is low, and is straightforward to function.
This resolution, moreover being very simple from a constructive viewpoint, makes the motor-flywheel group extremely insensitive to the vibrations and to the robust decelerations it’s subjected to for the kind of operation that the press is required to hold out.

Screw Presses Screw presses are usually not as broadly utilized in North America as mechanical presses, however distinctive screw press traits are driving an increase of their use. Acutually, there isn’t any distinction with standard type which consumes all flywheel power and powerful forging is feasible.
Oil-hydraulic motors, specifically axial piston motors, have a subtantially lower specific weight with small dimensions than electrical motors, so that they are often organized, individually or in pairs, on diametrically reverse a driving pinion, with the additional structural benefit that the spindle together with the flywheel and the toothed rim can be mounted axially displaceably in a nut mounted in the upper cross member of the press frame and are thus exposed only to torsion above the nut and only to thrust below the nut.
