Abstract
The utility model discloses a worktable moving device of hydraulic press, which can guarantee the plunger piston stability of moving cylinder of worktable. The worktable moving device of hydraulic press comprises a worktable moving cylinder in which the plunger piston is connected with the worktable. The plunger piston is connected with a supporter which is used for preventing the flagging of plunger piston. The supporter can prevent the flagging caused by the self-weight in extending of plunger piston. A problem of inferior stability of plunger piston operation caused by long moving stroke of worktable is settled. Simultaneously the abrasion of guide sleeve and sealing of moving cylinder of worktable can be reduced. The worktable moving device of worktable of hydraulic press is especially suitable for the large-scale open-die forging hydraulic press.
Description
Technical field
The utility model relates to hydraulic press, is specifically related to the movable workbench device of hydraulic press.
Background technology
On the sill of existing large free forging hydraulic press moving bolster is installed.The movable workbench cylinder that is arranged on the workbench both sides that moves through of this workbench promotes to realize.Specifically, the plunger in the movable workbench cylinder of both sides is connected with Working table floating respectively, when needing travelling table, and the elongation of the plunger of a side, and the corresponding shortening of the plunger of opposite side, and workbench is moved to the direction that requires.During the work of large free forging hydraulic press, because the workbench sinking that causes after the distortion of the rocking of hydraulic press, sill and workbench, the changing of the relative positions of workbench and the slide plate wearing and tearing etc. all can aggravate the wearing and tearing of movable workbench cylinder guide pin bushing and sealing, the service life of reducing the sealing of movable workbench cylinder.Especially because the shift motion of large-scale hydraulic press workbench is longer, the effect head portion sag of chain in deadweight when plunger all stretches out is bigger, not only influences the pressurized stability of plunger, and also can aggravate the wearing and tearing of movable workbench cylinder guide pin bushing and sealing simultaneously.
The utility model content
The technical problem that the utility model solved is: the movable workbench device that a kind of hydraulic press of the plunger stability that guarantees the movable workbench cylinder is provided.
The technical scheme that solves the problems of the technologies described above is: the movable workbench device of hydraulic press, comprise the movable workbench cylinder, and the plunger in the described movable workbench cylinder is connected with workbench, and described plunger is connected with and is used to the bracing or strutting arrangement that prevents that plunger is sagging.
Further be that described bracing or strutting arrangement is near the head setting of plunger.
Further be that described plunger is a hollow-core construction.
Further be that the head of described plunger is connected with the workbench ball pivot.
The beneficial effects of the utility model are: bracing or strutting arrangement can prevent when plunger extends because the effect of deadweight takes place sagging, solved problem, also can reduce the guide pin bushing of movable workbench cylinder and the wearing and tearing of sealing simultaneously because of the long plunger poor work stability that is caused of movable workbench stroke.The movable workbench device of this hydraulic press is particularly useful for the large free forging hydraulic press.
Description of drawings
Fig. 1 is the structural representation of the movable workbench device of the application's hydraulic press.
Fig. 2 is the structural representation of bracing or strutting arrangement among Fig. 1.
Be labeled as among the figure: workbench 1, plunger 2, movable workbench cylinder 3, bracing or strutting arrangement 4, bracing frame 41, support wheel 42, ball ring 5, top 6, gland 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1～shown in Figure 2, the movable workbench device of hydraulic press of the present utility model comprises movable workbench cylinder 3, and the plunger 2 in the described movable workbench cylinder 3 is connected with workbench 1, and described plunger 2 is connected with the bracing or strutting arrangement 4 that is used to prevent that plunger 2 is sagging.Bracing or strutting arrangement 4 can prevent that the effect generation owing to deadweight is sagging when plunger 2 extends, and has solved the problem because of long plunger 2 poor work stability that caused of workbench 1 shift motion, and the while also can reduce the guide pin bushing of movable workbench cylinder 3 and the wearing and tearing of sealing.Bracing or strutting arrangement 4 can adopt multiple structure, and such as a kind of bracing or strutting arrangement 4 shown in Fig. 2, it comprises the support wheel 42 that bracing frame 41 that is sleeved on the plunger 2 and the bottom that is installed in bracing frame 41 are axially rolled along plunger 2.This bracing or strutting arrangement 4 adopts the mode of rolling and supporting, and support wheel 42 rolls on the guide rail of sill, supports plunger 2 by bracing frame 41, eliminates workbench and sinks and the sagging influence in plunger 2 ends, alleviates the guide pin bushing of movable workbench cylinder 3 and the wearing and tearing of sealing greatly.Because the sag of chain maximum of plunger 2 heads, therefore above-mentioned bracing or strutting arrangement 4 better supports with the head to plunger 2 preferably near the head setting of plunger 2.In addition,, plunger 2 can be designed to hollow-core construction, alleviating its weight, thereby prevent that better plunger 2 is sagging as Fig. 1.
In addition, as shown in Figure 1, the head of plunger 2 is connected with workbench 1 ball pivot.A kind of concrete structure that is connected with workbench 1 ball pivot as plunger 2 heads, the head of described plunger 2 is equipped with the top 6 of a dribbling face, the suitable ball ring 5 of sphere of one of clamping and top 6 between described top 6 and the workbench 1, described ball ring 5 with come directly towards 6 between axially be connected by gland 7.The head of plunger 2 is connected with workbench 1 ball pivot, can either plays the effect of certain positioning supports, possess certain flexibility again simultaneously, so structure is more reasonable, moves more reliable the head of plunger 2.
