Description
Technical field
The utility model relates to a kind of fast Pressesforging hydraulic pressure unit master cylinder.
Background technique
Fast Pressesforging is a kind of important machine tool in machinery industry, is mainly used in the cogging of steel ingot and the pressure processing of open die forgings, is particularly suitable for the forging of alloying constituent higher material, play very important role in mechanical processing industry.As the master cylinder of one of fast Pressesforging hydraulic pressure unit core component, the quality of its project organization and performance, stability when directly affects fast Pressesforging hydraulic press group job and reliability.
Existing fast Pressesforging hydraulic pressure unit master cylinder used, the typical structure that its internal main is wanted has: long copper sheathing provides plunger motion to lead, use V-type combined seal ring to realize sealed high pressure oil, short copper sheathing compresses V-type combined seal ring, uses wool felt to prevent dust or foreign matter from entering oil cylinder inside.And in the normal work and daily maintenance of fast Pressesforging, often be faced with following problem: plunger master cylinder plunger face has obviously pulls vestige, master cylinder seal failure causes leakage of oil serious, these all bring considerable influence to master cylinder operation stability and operational safety, cause master cylinder maintenance cost comparatively large, working life is shorter.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of functional reliability, the stability that can improve fast Pressesforging, reduces fast Pressesforging later maintenance cost, the fast Pressesforging hydraulic pressure unit master cylinder increased the service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of fast Pressesforging hydraulic pressure unit master cylinder, comprise cylinder body, be fixed on the gland of cylinder ends and slip and be located at plunger in cylinder body, long copper sheathing and short copper sheathing is respectively equipped with between described inboard wall of cylinder block and plunger periphery, plunger is slidably matched with the endoporus of long copper sheathing and short copper sheathing respectively, combined seal ring is provided with between long copper sheathing and short copper sheathing, described short copper sheathing has the first cylindrical body and second cylindrical body of integrative-structure, first cylindrical body bi-side are stuck between combined seal ring end face and gland internal surface, second cylindrical body puts in gland endoporus, second cylindrical body periphery and gland endoporus drive fit, second cylindrical body endoporus and plunger periphery are slidably matched, gland exterior edge face is arranged with the dust ring being fastened in plunger periphery.
Preferably, described dust ring is " L " shape wiper of rubber.
The beneficial effects of the utility model are: the utility model is by increasing short copper sheathing length, plunger and gland are separated, utilize the characteristic that copper sheathing material is soft compared with steel, prevent plunger directly to contact with gland and cause plunger surface to produce pull, wear phenomenon, dust ring can effectively prevent periphery dust or foreign matter from entering cylinder interior, thus improve operation stability and the functional reliability of master cylinder, decrease maintenance cost, increase the service life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural principle schematic diagram of the present utility model.
The 1. long copper sheathing 5. of cylinder body 2. gland 3. plunger 4. short copper sheathing 5-1. first cylindrical body 5-2. second cylindrical body 6. combined seal ring 7. dust ring in figure
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The fast Pressesforging hydraulic pressure of one as shown in Figure 1 unit master cylinder, comprise cylinder body 1, be fixed on the gland 2 of cylinder body 1 end and the plunger 3 be located in cylinder body 1 that slides, long copper sheathing 4 and short copper sheathing 5 is respectively equipped with between described cylinder body 1 inwall and plunger 3 periphery, plunger 3 is slidably matched with the endoporus of long copper sheathing 4 and short copper sheathing 5 respectively, is provided with combined seal ring 6. between long copper sheathing 4 and short copper sheathing 5
Described short copper sheathing 5 has the first cylindrical body 5-1 and the second cylindrical body 5-2 of integrative-structure, first cylindrical body 5-1 bi-side are stuck between combined seal ring 6 end face and gland 2 internal surface, second cylindrical body 5-2 puts in gland 2 endoporus, second cylindrical body 5-2 periphery and gland 2 endoporus drive fit, second cylindrical body 5-2 endoporus and plunger 3 periphery are slidably matched, by extending short copper sheathing length, second cylindrical body 5-2 of short copper sheathing is put in gland endoporus, plunger 3 surface is separated with the endoporus steel wall of gland 2, because copper material is soft compared with steel, therefore can prevent when forging and pressing steel ingot, cause the lateral force of various different direction to master cylinder because of out-of-shape, plunger 3 surface is contacted with the endoporus steel wall of gland 2 causes plunger 3 surface pull and wear and tear, improve the sealing effect of master cylinder, extend its working life.
Gland 2 exterior edge face is arranged with the dust ring 7 being fastened in plunger 3 periphery, this dust ring 7 have employed " P6 " L shape wiper of rubber of German Merkel, it is inner that it can effectively prevent periphery dust or foreign matter from entering cylinder body 1, and then can prevent dust or foreign matter from causing plunger 3 surface to pull, dust or foreign matter is avoided to be mixed into hydraulic oil pollution hydraulic system, ensure that operation stability and the functional reliability of hydraulic system, decrease maintenance cost.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
