Description
Technical field
The utility model relates to press technologies field, especially relates to a kind of power-assisted servo-pressing machine.
Background technology
Forcing press drives operating mechanism by motor through transmission mechanism, treats pressing component and applies pressure, different according to work structuring type, forcing press can be divided into fly press, crank press and hydraulic press three major types.
Fly press screw rod, nut are transmission mechanism, and are the metal forming machinery pumped of slide block by the forward backward rotation movement transition of flywheel by worm drive.During work, motor makes flywheel accelerate to rotate with stored energy, promotes slide block simultaneously move downward by screw rod, nut, when shoe contact workpiece, flywheel is forced to be decelerated to and stops completely, and the rotation function of storage changes impact energy into, hits workpiece by slide block, make it distortion, after strike completes, motor makes flywheel reverse, and band movable slider rises, get back to home position, one action process completes.
Application number is disclose a kind of hydraulic screw press in the utility application of 201210484194.8, this machine in use, start the hydraulic system of high-voltage oil cylinder, hydraulic system pressure is made to reach rated pressure and by accumulator storage power, brake is made to throw off flywheel by electric control system during work, hydraulic oil enters the epicoele of cylinder body through upper hydraulic fluid port simultaneously, again through the lower hydraulic fluid port oil extraction of cavity of resorption, such piston rod can promote slide block and move downward rapidly, because screw pair adopts non-self-lock-ing screw thread, therefore the rectilinear motion that slide block is downward will change the rotary motion of flywheel along screw rod into.Slide block also increases with gathering way of Bottom Runby thereupon, and flywheel obtains enough rotary accelerations, and then assembles blow energy.When slide block down is to when contacting workpiece on working plate, the energy that flywheel discharges carries out hammering to workpiece, and flywheel slows down thereupon.When slide block down is to stroke end, flywheel stops operating and releases whole energy, and hammering terminates.Now slide block is owing to ging up rapidly by powerful hammering reaction force, electrical apparatus control system makes control valve commutate simultaneously, the lower hydraulic fluid port of high-voltage oil cylinder is made to enter high pressure liquid force feed, and by the outer oil extraction of upper hydraulic fluid port, such slide block can continue to go up, when the terminal that slide block gos up to stroke, by electrical apparatus control system, reversal valve cuts out, high-voltage oil cylinder quits work, and brake makes flywheel stall, so completes and once forges and presses process.High pressure machine by accumulator accumulation of energy and by high-voltage oil cylinder promote slide block move downward, can flywheel be made to obtain enough rotary accelerations under little power consumption state, and then gathering blow energy, there is the advantage that power consumption is low, strike effect is good, but complicated integral structure, the slide block being in impulse stroke under wheel action are in accelerated motion state, there are certain shock and vibration when applying pressure to workpiece in the slide block under acceleration mode, cannot ensure the needs of high accuracy forging and stamping process.
