By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
Refer to Fig. 1 to Fig. 3.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, all should still drop in scope that disclosed technology contents can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
As shown in Figure 1, 2, 3, the invention provides a kind of plunger type hydraulic screw press, it comprises a frame, this frame is made up of crossbeam 11, guide beam 13, column 14, base 20, frame can be arranged working plate 18, centring ring 19, frame is also connected with pull bar 17, and pull bar 17 is fixed by pull-rod nut 22, thus makes frame form a general frame structure.
Frame is provided with rotatable screw rod 7, and screw rod 7 coordinates with a nut 15.5 and forms screw pair, and nut 15.5 is positioned at a slide block 15.Slide block 15 comprises a slide body 15.7, the upper end of slide body 15.7 is provided with a nut sleeve 15.6, nut 15.5 is positioned at nut sleeve 15.6, nut 15.5 passes through flat key 15.4 stationary fit in nut sleeve 15.6, and is fixedly connected on slide body 15.7 with pressing plate 15.3, stud 15.2, round nut 15.1.The lower end of slide body 15.7 is provided with a slide block backing plate 15.8, and slide block backing plate 15.8 is fixedly connected with slide body 15.7 by bolt 15.9.
The upper end of screw rod 7 is connected with a flywheel 1, and flywheel 1 is fixedly connected with screw rod 7 by flat key 6, clamp nut 4, hold-down bolt 3.Flywheel 1 is made up of core wheel 1.5 and wheel rim 1.4, and wheel rim 1.4 is enclosed within the outside of core wheel 1.5, and wheel rim 1.4 is fixedly connected with core wheel 1.5.In order to prevent overload, adopting the method rubbing and be fixedly connected with between core wheel 1.5 with wheel rim 1.4, namely brake pad 1.3 being set between core wheel 1.5 and wheel rim 1.4, then make the edge of wheel rim 1.4 compress the edge of core wheel 1.5 by butterfly spring group 1.1 and pressing plate 1.2.Like this when load is less, the frictional force by brake pad drives wheel rim 1.4 to rotate by core wheel 1.5, and when load force is greater than the frictional force of brake pad 1.3, wheel rim 1.4 can not rotate with core wheel 1.5, but skids relative to core wheel 1.5.
For the ease of braking, flywheel 1 is also connected with a brake 2, and brake 2 is fixed on brake support frame 10.In order to reduce frictional resistance, flywheel 1, screw rod 7 are supported on the crossbeam 11 of frame by bearing 5.Be provided with a round boss in the middle part of screw rod 7, be provided with plain thrust bearing in frame, plain thrust bearing is set on the round boss of screw rod, and this plain thrust bearing is made up of cushion block 8 and heel block 9, can increase the ability that screw rod bears hammering power like this.
Frame is also provided with high-voltage oil cylinder 12, and high-voltage oil cylinder 12 is made up of cylinder body 12.1 and piston rod 12.2, and cylinder body 12.1 is provided with hydraulic fluid port A and lower hydraulic fluid port B, can promote piston rod 12.2 move up or down by different hydraulic fluid port oil-feed.The piston rod 12.2 of high-voltage oil cylinder 12 is connected with slide body 15.7 by hold-down nut 12.3, and such piston rod just can be with movable slider 15 to move up and down.
This fly press in use, start the hydraulic system of high-voltage oil cylinder 12, the pressure of hydraulic system is made to reach rated pressure and by accumulator storage power, brake 2 is made to throw off flywheel 1 by electrical apparatus control system during work, hydraulic oil enters the epicoele of cylinder body 12.1, the lower hydraulic fluid port B oil extraction by cavity of resorption through upper hydraulic fluid port A simultaneously, such piston rod 12.2 can promote slide block 15 and move downward rapidly, because screw pair adopts non-self-lock-ing screw thread, the rectilinear motion that therefore slide block 15 is downward will change the rotary motion of flywheel 1 along screw rod 7 into.Slide block 15 also increases with gathering way of Bottom Runby thereupon, and such flywheel 1 just can obtain enough rotary accelerations, and then assembles blow energy.When slide block down is to contact working plate workpiece, flywheel 1 releases energy and carries out hammering to workpiece, and flywheel slows down thereupon, and when slide block 15 comes downwards to stroke end, when flywheel 1 stops operating and puts whole energy, hammering terminates.Now slide block 15 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 B of high-voltage oil cylinder 12 is made to enter high pressure liquid force feed, and by the outside oil extraction of upper hydraulic fluid port A, such slide block 15 can continue to go up, when the terminal that slide block 15 gos up to stroke, by electrical apparatus control system, reversal valve cuts out, high-voltage oil cylinder 12 quits work, and brake 2 work simultaneously makes flywheel 1 stop the rotation, and can complete like this and once forge and press process.Ejecting for the ease of workpiece, is provided with liftout attachment 16 in slide block backing plate 15.8, the base 20 of frame is provided with lower liftout attachment 21.
In order to improve this fly press offset load resistance, the middle part of frame is provided with a guide beam 13, and the position of guide beam 13 is corresponding with the position that slide block 15 top nut overlaps 15.6.Guide beam 13 is provided with a pilot hole, is provided with a fairlead 23 in pilot hole, and nut sleeve 15.6 is positioned at this fairlead 23, and nut sleeve 15.6 can move up and down along fairlead 23.The corner of slide body 15.7 is respectively equipped with a slide guide strip 25, frame is provided with the guide rail 24 corresponding with slide guide strip 25 position, slide guide strip 25 matches with guide rail 24, and four slide guide strips 25 are arranged in X-shaped with slide body 15.7, the ratio of width to height of slide block can be made like this to significantly improve, and then effectively improve fly press offset load resistance.
The slide block of this fly press is connected with high-voltage oil cylinder, promote slide block by high-voltage oil cylinder to move down, slide block is moved down in process and is rotated by screw rod flywheel driven, distance along with slide block down increases its descending speed and also increases thereupon, such flywheel just can obtain enough rotary accelerations, and then assembles blow energy, when slide block down is to during with absorption surface, flywheel can carry out hammering to workpiece, stops operating until flywheel discharges whole energy.This plunger type hydraulic screw press adopts hydraulic accumulator energy storage, eliminate the defect of friction press friction skidding loss mechanical kinetic energy, to overcome electric screw press installed capacity large, the defect that Fraquent start electric current is large, solution clutch spiral press complicated in mechanical structure, the defect that manufacturing cost is high, this fly press has the advantages such as manufacture and use cost is low, simple to operate, easy to maintenance, energy-saving effect is obvious.In sum, the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
