Description
Technical field
The invention belongs to hydraulic press, particularly relate to a kind of simple in structurely, knockout press is big, can reduce the stripper in use for large sized hydraulic machine of hydraulic press overall volume.
Background technology
At present, along with large hydraulic press has appearred in industrial expansion, as the appearance of the large hydraulic press of several kilotons.Important process parts for hydraulic press have been oil cylinders of punching press effect.Described oil cylinder roughly is by the cylinder body with hydraulic fluid port and is arranged on cylinder interior that the piston that can prolong the upper and lower motion of inwall of cylinder body under the effect of oil pressure constitutes.Common hydraulic press is to adopt two-way cylinder, the upper and lower motion of driven plunger.
But, for the large hydraulic press of several kilotons,,, make the slide block quick return if want the smooth demoulding because workpiece is very big to the adhesion strength that mould produces, need very large backhaul power, just need the used oil of backhaul to have very large flow.That is flow and power when, required flow of backhaul and power will be much larger than work.So adopt the structure of the two-way cylinder of existing hydraulic press, do not reach the required backhaul power of large hydraulic press oil cylinder piston, and two-way cylinder structure is used for the large hydraulic press of several kilotons at all, then will make the hydraulic press overall structure huge.
Summary of the invention
The present invention provides a kind of simple in structure for solving the technical problem that exists in the known technology, compactness, and knockout press is big, can reduce the stripper in use for large sized hydraulic machine of hydraulic press overall volume.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of stripper in use for large sized hydraulic machine, including cylinder body and be positioned at cylinder body also can be along the upper and lower plunger movable bar of its inwall, the upper end of described cylinder body is hatch frame and is stamped top cover, this top cover is fixed on the described hatch frame by screw, the center of this top cover is formed with the corresponding through hole of body of rod diameter with plunger rod, and the lower end of cylinder body is formed with the hydraulic fluid port to its inner oil-feed; The bottom of described plunger rod is formed with the boss of diameter greater than its body of rod, and top cover is run through in the upper end of plunger rod; Also be provided with diameter in plunger rod upper end greater than the external diameter of cylinder body and with the plunger rod cover plate of upper and lower motion together; Periphery at cylinder body also is with plectane, and the upper port of this plectane and the lower surface of cover plate are fixed together.
Also be provided with cylinder mouth guide pin bushing between the medial surface of described cylinder body upper port and the plunger rod.
One side of described cylinder body also fixedly installs by fastening block and is useful on the scale plate of setting stripping stroke, slidably be provided with lead limit switch on the scale plate, the while is formed with the corresponding stroke limit of described lead limit switch in the outside of the lower port of plectane hits ring.
The outside of described plectane lower port is formed with two stroke limits and hits ring, and the external diameter that one of them stroke limit hits ring hits the external diameter of ring greater than another stroke limit.
The top of described scale plate also is set with the locating part that closely contacts with plectane.
The upper end of described cover plate also is provided with cushion block.
Also be provided with air vent and bleed screw on the casing wall of described cylinder body.
Described cylinder body is to be arranged on the upper beam of hydraulic press by the fastening block of its side and bolting.
Advantage and good effect that the present invention has are: because stripper in use for large sized hydraulic machine of the present invention adopts said structure, manufacture simply, and compact conformation, knockout press is big, and can reduce the hydraulic press overall volume.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, enumerate following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1; stripper in use for large sized hydraulic machine of the present invention; including cylinder body 7 and be positioned at cylinder body 7 also can be along the upper and lower plunger movable bar 10 of its inwall; the upper end of described cylinder body 7 is hatch frame and fixedly is stamped top cover 16 by screw 3; these top cover 16 centers are formed with the corresponding through hole of body of rod diameter with plunger rod 10, and the lower end of cylinder body 7 is formed with the hydraulic fluid port 18 to its inner oil-feed.The bottom of described plunger rod 10 is formed with the boss 15 of diameter greater than its body of rod, and top cover 16 is run through in the upper end of plunger rod 10.Also be provided with cylinder mouth guide pin bushing 4 between the medial surface of described cylinder body 7 upper port and the plunger rod 10.Also be provided with diameter in the upper end of plunger rod 10 greater than the external diameter of cylinder body 7 and with plunger rod 10 cover plate 2 of upper and lower motion together; Periphery at cylinder body 7 is with plectane 5, and the lower surface of the upper port of this plectane 5 and cover plate 2 is fixed together.
One side of described cylinder body 7 also fixedly installs by fastening block 14 and is useful on the scale plate 12 of setting stripping stroke, the top of scale plate 12 is set with the locating part 17 that closely contacts with plectane 5, also slidably be provided with the lead limit switch 11 that is used to regulate demoulding height on the scale plate 12, the while is formed with described lead limit switch 11 corresponding stroke limits in the outside of the lower port of plectane 5 hits ring.This trip is spacing to be hit ring and is formed with 2, and the external diameter that one of them stroke limit hits ring 9 hits the external diameter of ring 8 greater than another stroke limit.
The upper end of described cover plate 2 also is provided with cushion block 1, and this cushion block 1 can be provided with polylith as required, is to be used for the height that the regulator solution press is remained silent.
Also be provided with air vent and bleed screw 6 on the casing wall of described cylinder body 7, be used for regularly exitting.
Described cylinder body 7 is to be fixedly installed on the upper beam of hydraulic press by the fastening block 14 of its side and bolt 13.
When the needs demoulding, by hydraulic fluid port 18 oil-feed in cylinder body 7, oil upwards promotes plunger rod 10, and plunger rod 10 promotes cushion block 1 by cover plate 2, and cushion block 1 upwards promotes the purpose that slide block reaches the demoulding again.Moving up in demoulding cover plate 2 also drives plectane 5 and moves up, and when plectane 5 is moved upwards up to position stroke limit thereon and hits ring 9 impact stroke limit switches 11, represents that then the demoulding finishes.
