Description
Technical field
The utility model relates to hydraulic press field, especially a kind of lower material returned cylinder.
Background technique
Liftout is step indispensable in die molding process, and workpiece needs to pass through material jacking mechanism after forming in die cavity
Workpiece is ejected into die cavity pickup.Existing hydraulic press liftout is usually the oil cylinder by being realized by the oil cylinder on the downside of board is arranged in
Piston is directly connected with mandril, so that piston activity is to drive mandril to jack up workpiece, but this mode has a problem that.Mold
When molding in order to make workpiece be easier demould, it usually needs oil in die cavity, hydraulic press correspondingly the most commonly used is forging and stamping oil, forging
Pressure oil is easy to flow to lower piston down along jogger hole, so that the sealing ring between piston and piston cylinder easily corrodes, causes
Oil cylinder oil leak.
Utility model content
Technical problem to be solved by the utility model is: provide a kind of lower material returned cylinder, prevent the Seal Oil on mandril from
Piston is flowed to, sealing ring between piston and cylinder body is prevented to be corroded.
The solution that the utility model solves its technical problem is:
A kind of lower material returned cylinder, including cylinder body and piston, the piston are slidably connected with cylinder body, and the piston is far from cylinder body
One end is equipped with link block, and the link block is equipped with piston mounting holes and mandril mounting hole, the piston mounting holes, mandril installation
Hole is not connected to mutually.
As a further improvement of the above technical scheme, the downside of the mandril mounting hole is equipped with dredging hole, the mandril
Mounting hole is connected to extraneous by dredging hole.
As a further improvement of the above technical scheme, the upper surface of the link block is equipped with the gear oil bone of whole circle.
As a further improvement of the above technical scheme, the upper surface of the link block is additionally provided with oil-containing groove.
As a further improvement of the above technical scheme, the bottom surface of the oil-containing groove is angularly disposed, on the link block also
Equipped with outage, the outage is located at the lowest part of the bottom surface of oil-containing groove.
The beneficial effects of the utility model are: traditional hydraulic press, makes piston and top by the way that screw hole is arranged on piston
Bar is directly connected to, and the forging and stamping oil above mandril at workspace is easy to flow down at piston by mandril movable span, corrodes piston
Sealing ring between cylinder body, the technical program is by connecting piston by link block with mandril, so that work above mandril
The forging and stamping oil in area cannot flow directly at piston, so as to play a protective role to the sealing ring between piston and cylinder body.
The utility model relates to hydraulic press field, especially a kind of lower material returned cylinder.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the elevational cross-sectional view of the utility model embodiment；
Fig. 2 is partial enlarged view at the A of the utility model embodiment.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connections being previously mentioned in text or connection relationship, not singly refer to that component directly connects, and referring to can be according to specific
Performance, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the utility model is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Embodiment is as follows, referring to figs. 1 to Fig. 2, a kind of lower material returned cylinder, including cylinder body 6 and piston 5, and the piston 5 and cylinder body
6 are slidably connected, and the piston 5 is equipped with link block 4 far from one end of cylinder body 6, and the link block 4 is equipped with piston mounting holes and top
Bar mounting hole 41, the piston mounting holes, mandril mounting hole 41 are not connected to mutually.Traditional hydraulic press, by being arranged on piston
Screw hole is directly connected to piston with mandril, and the forging and stamping oil above mandril at workspace is easy to flow down to by mandril movable span
At piston, corrode the sealing ring between piston and cylinder body, the technical program makes by connecting piston by link block with mandril
The forging and stamping oil for obtaining workspace above mandril cannot flow directly at piston, to play guarantor to the sealing ring between piston and cylinder body
Shield effect.
It is further used as preferred embodiment, the downside of the mandril mounting hole 41 is equipped with dredging hole 411, the mandril
Mounting hole 41 is connected to the external world by dredging hole 411.Forging and stamping oil on the upside of workbench is easy to flow into mandril mounting hole along mandril, top
When having forging and stamping oil in bar mounting hole, when installing mandril, on the one hand forges and presses oil and be easy the air bottled up in mandril mounting hole, so that
Air cannot be smoothly discharged, and cause mandril that can not be installed in place；On the other hand forging and pressing oil itself, there are certain volume, forging and stamping oil
The installation of mandril can be caused to hinder, so that mandril is difficult to attach to position；Thus by being equipped with dredging hole, so that mandril mounting hole
Lower section is in communication with the outside, and forging and stamping oil can be smoothly discharged with air, prevents the above situation, improves the installation accuracy of mandril.
It is further used as preferred embodiment, the upper surface of the link block 4 is equipped with the gear oil bone 42 of whole circle.By setting
The oily bone of gear is set, forging and stamping oil is not easy to wander to the piston of downside when flowing down along mandril.Further, the lateral dimension of the gear oil bone
It is bigger than cylinder body, so that forging and pressing oil will not be on runner cylinder body from keeping off when oily bone flows out.
It is further used as preferred embodiment, the upper surface of the link block 4 is additionally provided with oil-containing groove 43.It is connect by setting
Oil groove, forging and stamping oil are not easy to wander to the piston of downside when flowing down along mandril.
It is further used as preferred embodiment, the bottom surface of the oil-containing groove 43 is angularly disposed, also sets on the link block 4
There is outage 431, the outage 431 is located at the lowest part of the bottom surface of oil-containing groove 43.The bottom surface of oil-containing groove is angularly disposed, row
The lowest part of oil-containing groove bottom surface is arranged in oilhole, to can flow to outage using from heavy oil, is connected to fuel tank by pipeline,
Prevent oil-containing groove forging and stamping oil accumulation is excessive from overflowing.
The better embodiment of the utility model is illustrated above, but the utility model be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
