Description
Technical field
The utility model relates to a kind of mechanism that cold isostatic press carries out lifting to super large cylinder diameter press bottom end cover that is mainly used in.
Background technology
In the isostatic pressing technology application, along with the continuous increase of user to compacting workpiece demand, the working cylinder effective diameter will improve significantly, bottom end cover weight also significantly increases, can not satisfy the equipment requirement with traditional rectangle spring lifting or annular cylinder lifting, more can not satisfy enough big lifting force requirement.Bottom end cover hoisting mechanism (see figure 4) in the traditional cold isostatic pressing machine generally adopts array rectangle spring 12 by bolt 10 bottom end cover 6 to be connected on the working cylinder 9.Therefore, need dismantle array rectangle spring 12 and the nut 11 that links, bolt 10 when bottom end cover 6 cleans, will support with large-tonnage jack simultaneously, could slowly put down, working procedure is very loaded down with trivial details.When reinstalling bottom end cover 6, then must assurance respectively organize the uniformity of rectangle spring 12 pre compressed magnitudes, installation accuracy requires high.When bottom end cover weight was too heavy, the version that also can adopt annular cylinder to promote satisfied the requirement that resets of large-tonnage isostatic pressing machine bottom end cover.Owing to be subjected to the restriction of installing space, the maintenance of bottom end cover, cleaning and installation are all extremely inconvenient, the difficulty that resets, and work safety hidden danger is big.Need dismounting One's name is legion is fixed on the big specification screw in the annular cylinder, also will support with large-tonnage jack in the bottom end cover bottom simultaneously, just can slowly put down.And be difficult for centering when resetting, and difficulty is installed, hold-down screw need connect again, tighten, very consuming time taking a lot of work.
Summary of the invention
The purpose of this utility model is to provide a kind of and reset accurately and reliably at the weak point of above-mentioned prior art existence, and is convenient for installation and maintenance, work safety, saving of work and time, and the big bottom end cover automatic hoisting mechanism of lifting force.
The purpose of this utility model can reach by following measure, a kind of bottom end cover elevating mechanism that the utility model provides, comprise isostatic pressing machine working cylinder and bottom end cover, it is characterized in that: be fixedly connected with connection guide 4 and the support arm 5 that is connected the oil cylinder piston bar respectively in bottom end cover 6 both sides, be fixedly connected on the support arm 5 extension supports and in the guide 4 guide pillar 1 that moves be housed in guide, two hydraulic jacks 3 that are connected on the bottom end cover 6 both sides support arms 5 are fixed on the isostatic pressing machine working cylinder by the bearing on its tailstock 2.Guide pillar 1 lower end connects firmly on support arm 5 by big specification nut, and the upper end is unfixing, and when bottom end cover 6 descended, guide pillar 1 together descended with bottom end cover 6, play the guiding role.
The utility model has following beneficial effect than prior art.
The two oil cylinders of the lifting that the utility model connects firmly at super large cylinder static pressure machine bottom end cover, the elevating mechanism by the lifting of four guide pillars guiding are compared with traditional rectangle spring and annular cylinder mechanism, it is big to have lifting force, lifting is steady, it is convenient that the bottom end cover sealing ring is changed and cleaned, and bottom end cover resets accurately, work safety, efficient, saving of work and time, safeguard easy to use, the advantage that cost is low.Elevating mechanism passes through two hydraulic jack synchronization lifting bottom end covers, and leading by lead guarantees resetting accurately and reliably of bottom end cover, has avoided the shortcoming that the prior art lifting force is little, inconvenience is installed.In the ascending, descending process of the long stroke of bottom end cover, without any need for auxiliary mould, the cleaning at sealing position and sealing ring are changed efficient and convenient, have saved press and have safeguarded use cost.

The specific embodiment
Among Fig. 1, Fig. 2, be separately installed with the enough support arms of bending strength 5 in super large cylinder diameter press bottom end cover 6 both sides.Two hydraulic jack 3 tailstocks are fixed on the working cylinder by the bearing 2 that extends outside both sides, and the oil cylinder piston bar connects with support arm 5.Four guide pillars 1 are provided with synchronous valve simultaneously by guide 4 positioning and guiding bottom end covers 6 reseting precisions in the hydraulic circuit of hydraulic jack, guarantee that the two hydraulic jack speeds of travel are synchronous, realize that the bottom end cover elevating movement continuously, steadily.Adopt long stroke oil cylinder, bottom end cover can be sealed the position cylinder mouth of all deactivating, be convenient to the cleaning and the sealing ring at bottom end cover sealing position are changed.Bilateral support arm 5 usefulness number screw and bottom end cover 6 are linked together, and are fixed with two guide pillars 1 on every side support arm 5, and hydraulic jack 3 afterbodys are fixed on the working cylinder 9, and piston rod head and support arm 5 link.The elevating movement of hydraulic cylinder piston rod passes to bottom end cover 6 and guide pillar 1 by support arm, and guide pillar 1 is by four guide 4 positioning and guidings that are separately fixed on the isostatic pressing machine working cylinder 9, and then the accuracy of alignment when guaranteeing that bottom end cover 6 is into and out of working cylinder 9.Guide pillar 1 lower end connects firmly on support arm 5 by big specification nut, and the upper end is unfixing, and when bottom end cover 6 descended, guide pillar 1 together descended with bottom end cover 6, play the guiding role.
In Fig. 3,, be provided with the Machine guarding of forming by set bolt 7 and protection nut 8 in bottom end cover 6 both sides for preventing accident.This Machine guarding is mounted on the center line that working cylinder is axially symmetry with the bottom end cover; the bearing-surface of protection nut 8 has the distance of 5～10mm apart from bottom end cover 6 convex edges; when even the decline of bilateral hydraulic jack 3 piston rods accident occurring; protected nut 8 is held behind bottom end cover 6 declines 5～10mm; prevent that bottom end cover 6 from further descending; come off, guaranteed the safe and reliable of this system effectively.
In the isostatic pressing machine use, when bottom end cover 6 needs to promote, feed pressure oil in hydraulic jack 3 rod chambers, the lifting force of generation overcomes weight such as bottom end cover 6, workpiece, working media, and bottom end cover 6 is risen to upper limit position.When depositing between bottom end cover 6 and the working cylinder 9 that impurity need clean and when changing seal; remove mechanical protection earlier; in hydraulic jack 3 rodless cavities, feed hydraulic oil again; by the synchronous valve that is provided with in the hydraulic system Synchronization Control, can guarantee that bottom end cover 6 drops to the lower position reposefully to oil cylinder piston bar movement velocity.
