Detailed description of the invention
Below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, do not limit the utility model.
Refer to Fig. 1, large-tonnage of the present utility model little table top short stroke cylinder moving type plunger case is mainly used in hydraulic press.Incorporated by reference to Fig. 2, large-tonnage little table top short stroke cylinder moving type plunger case comprises master cylinder 14, slide block 13, plunger rod 6, one group of V group sealing ring 11, upper fairlead 10, lower fairlead 2 12, supported flange 8, topping up valve seat 12.Upper fairlead 10, lower fairlead 2 12 all can lead for copper sheathing.
Incorporated by reference to Fig. 3 and Fig. 4, slide block 13 to be enclosed within master cylinder 14 and to be welded as a whole with master cylinder 14, and the excircle dimension of master cylinder 14 can exceed the mesa dimensions of slide block 13.Plunger rod 6 can be central hollow structure, for preventing surface corrosion and increasing case hardness, the moving surface built-up welding stainless steel of plunger rod 6, or hard chrome plating.From top to bottom, upper fairlead 10, V group sealing ring 11, lower fairlead 2 12 are all fixed on the madial wall of master cylinder 14, and V group sealing ring 11 is clipped between upper and lower two fairleads.
Supported flange 8 is fixed on the one end of master cylinder 14 extending master cylinder 14 for pressure holding at upper fairlead 10, supported flange 8 is fixed on the upper plane of slide block 13 by multiple screw (sign) and adjustment pad 9, press against on the upper plane and upper fairlead 10 of master cylinder 14.Supported flange 8 also can be provided with dust ring 7.
One end of plunger rod 6 is housed in master cylinder 14 through V group sealing ring 11, two fairleads, and the other end of plunger rod 6 installs topping up valve seat 2.The top of topping up valve seat 2 is provided with oil-in flange 1, can be provided with the O type circle 4 being with single back-up ring between topping up valve seat 2 and plunger rod 6.Plunger rod 6 is connected on the lower plane of entablature 3 of described hydraulic press by connector 5, and topping up valve seat 2 can be fixed in the interior bone of entablature 3, and connector 5 can be attaching nut.
Therefore, cylinder moving type plunger case of the present utility model, plunger rod 6 upper end arranges topping up valve seat 2, topping up valve seat 2 connects hydraulic fluid port flange 1, large plunger rod 6 is connected to the lower plane of entablature 3 by attaching nut, then is fixed on the upper plane of slide block 13 by supported flange 8.Master cylinder body and master cylinder 14, be welded as a whole with slide block 13.Plunger rod 6 can adopt low Ni-Cr-Mo chilled cast iron, and interstitial hole adds macrostructure, i.e. material saving, reduces difficulty of processing again.Should be noted that: for preventing the casting flaws such as large plunger rod aerobic skin, before processing, its endoporus can bead.
The utility model adopts V group sealing ring 11 to seal, and two copper sheathing guiding, namely eliminate guidance tape and this spy is sealed envelope, facilitate installation again.When need repairing V group sealing ring 11 time, plunger rod need not be needed as conventional oil cylinder to remove just replaceable sealing ring.Only need remove the upper fairlead 10 of supported flange 8 and upper end, i.e. replaceable V group sealing ring 11.Install because V group sealing ring 11 is all openings.
Due to large-tonnage, the utility model adopts three cylinder combinations to drive slide block, and during F.F., hydraulic oil enters narrowing toward each end piston cylinder, and the servo-actuated generation negative pressure of plunger case broad in the middle, namely opens prefill valve oil suction, to realize the fast forward action of slide block.Plunger rod of the present utility model can adopt low Ni-Cr-Mo chilled cast iron material, and its upper end arranges topping up valve seat, and plunger rod is connected to the lower plane of entablature by attaching nut.The upper plane of slide block is fixed on again by supported flange.Described large plunger cylinder and slide block are welded as a whole.Simplify hydraulic press structure with this, alleviate machine weight, can greatly reduce hydraulic press manufacturing cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
