Abstract

The utility model discloses a large-stroke horizontal plunger cylinder and belongs to the technical field of hydraulic forging press equipment. The large-stroke horizontal plunger cylinder comprises a cylinder body, a plunger arranged at one end of the cylinder body, and a plunger rod placed in the cylinder body. The large-stroke horizontal plunger cylinder is characterized in that an idler wheel is arranged at the cylinder bottom end of the plunger rod, and the idler wheel is in pin connection with the plunger rod through a rotating shaft. According to the large-stroke horizontal plunger cylinder, the idler wheel is arranged at the cylinder bottom end of the plunger rod, and accordingly the cylinder bottom and a cylinder opening of the plunger rod have supports, so that balance performance of the plunger rod is guaranteed, the phenomena that when the plunger rod extends out, a plunger head is droopy are avoided, and meanwhile the diameter of the idler wheel and the inner diameter of the cylinder body are equal, and therefore sufficient supporting effect can be achieved, cylinder opening sealing and a guiding sleeve are protected, and sealing damage and oil leakage are avoided.

Description

The flat plunger case of long stroke water
Technical field
The utility model belongs to the forging hydraulic press equipment technical field, particularly relates to the flat plunger case of a kind of long stroke water.
Background technique
At present, fast development along with forging industry, the use amount of the flat plunger case of long stroke water is more and more higher, find in practice process, along with the stroke of horizontal columns plug cylinder constantly increases, the sagging probability of plug constantly increases, and sagging cylinder body and the plunger of very easily scratching of plug, therefore, design and develop a kind of passing through and guarantee the plunger rod balance, and then prevent the flat plunger case of the sagging long stroke water of plug.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, proposes the good flat plunger case of long stroke water of a kind of stability.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The flat plunger case of a kind of long stroke water comprises: cylinder body, be arranged at the plunger of described cylinder body one end and be placed in plunger rod in described cylinder body; Cylinder bottom end at described plunger rod is provided with roller, between described roller and described plunger rod by the rotating shaft pin joint.
As preferably, the utility model has also adopted following technological scheme:
The diameter of described roller equals the internal diameter of described cylinder body.
Advantage and the good effect that the utlity model has are: by adopting technique scheme; the utility model arranges roller by the cylinder bottom end at plunger rod; thereby make plunger rod, at cylinder bottom and cylinder mouth place, a support be arranged respectively; therefore guaranteed the balance of plunger rod, the sagging phenomenon of plug while having avoided plunger rod to stretch out, simultaneously; the diameter of roller equates with the internal diameter of cylinder body; therefore can play sufficient supporting effect, protection seal with annular groove and guide pin bushing, prevent the bad seals leakage of oil.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view of the present utility model.
Wherein: 1, plunger; 2, cylinder body; 3, plunger rod; 4, roller; 5, rotating shaft.
Embodiment
, for further understanding model utility content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, Fig. 2, the flat plunger case of a kind of long stroke water comprises: plunger 1, cylinder body 2, plunger rod 3 and roller 4; Wherein: plunger 1 is connected with an end of cylinder body 2, and plunger rod 3 is placed in cylinder body 2 inside, and roller 4 is located at the cylinder bottom end place of plunger rod 3, between roller 4 and plunger rod 3 by rotating shaft 5 pin joints.In order to guarantee the sealing between roller 4 and cylinder body 2, in this specific embodiment, the diameter of roller 4 equals the internal diameter of cylinder body 2.
Working principle of the present utility model is: the plunger rod of traditional horizontal columns plug cylinder only has a support at the cylinder mouth, therefore there is the poor defect of balance, this specific embodiment arranges roller 4 by the cylinder bottom end at plunger rod 3, like this, plunger rod 3 also has a support at the cylinder bottom place, like this, plunger rod 3 has two strong points, can effectively guarantee like this balance of plunger rod 3 when plunger rod 3 is flexible, prevents that plug is sagging; The diameter of roller 4 equates with the internal diameter of cylinder body 2 simultaneously, therefore can play sufficient supporting effect, and protection seal with annular groove and guide pin bushing, prevent the bad seals leakage of oil.
Above a kind of embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
