Description
Technical field
The utility model relates to hydraulic mechanism technical field, more particularly, relates to a kind of hydraulic press master cylinder body piston rod blank main cylinder device.
Background technique
Master cylinder is one of core component of hydraulic press, and it is primarily of cylinder body and piston two-part composition, and cylinder body and piston highi degree of accuracy are joined and be associated with relative movement.
Refer to Fig. 1, existing master cylinder, it is divided into cylinder body 11 and piston 12, and its cylinder body 11 is integral type castings, and piston 12 is divided into the casting of two-part spheroidal graphite cast iron or forging.Direct casting or forging complete cylinder body 11 have certain difficulty, and due in casting process, foundry goods easily produces the defects such as slag inclusion, pore and trachoma, also easily crack during quenching, when particularly the hole size of cylinder body is larger, more easily cause higher scrappage, and during integral type casting, once scrap, just cause relatively high economic loss, and there is the larger loss of scrapping in batches.And two-part of piston 12 are also larger, directly casting also easily causes the waste of material, and the manufacture cycle is longer.
In sum, how improving master cylinder, to save production cost, to shorten the manufacture cycle, and improve the quality of products, is current those skilled in the art's problem demanding prompt solution.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of hydraulic press master cylinder body piston rod blank main cylinder device, to save production cost, shortens the manufacture cycle, and improves the quality of products.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of hydraulic press master cylinder body piston rod blank main cylinder device, comprise cylinder body and piston, described piston is mobilizable to be arranged in described cylinder body; Described cylinder body comprises: cylinder bottom, is provided with shoulder hole in described cylinder bottom; The cylinder barrel be fixedly connected with described cylinder bottom; The cylinder head be fixedly connected with described cylinder barrel, is provided with through hole in described cylinder head.
Preferably, described piston comprises: bar head; The bar cylinder be fixedly connected with described bar head; The rod end be fixedly connected with described bar cylinder, and described rod end is in the outside of described cylinder body.
Preferably, welding is fixedly connected as described in.
Preferably, described cylinder body is 20 steel cylinder bodies.
Preferably, described piston is 45 steel pistons.
The hydraulic press master cylinder body piston rod blank main cylinder device that the utility model provides, the cylinder body of its master cylinder is divided into three sections, i.e. cylinder bottom, cylinder barrel and cylinder head, just can form cylinder body after three being fixedly connected with.This kind of structure, makes the cylinder body of master cylinder when solid forging, can avoid causing overall waste because of scrapping of a part, reduces scrappage; And segmentation manufacture, three parts can be welded simultaneously, shorten the manufacture cycle.Therefore, this hydraulic press master cylinder body piston rod blank main cylinder device has saved cost of production, shortens the manufacture cycle, and improves quality of product.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The structural representation of the hydraulic press master cylinder that Fig. 1 provides for prior art;
The structural representation of the cylinder body of the hydraulic press master cylinder body piston rod blank main cylinder device that Fig. 2 provides for the utility model embodiment;
The structural representation of the piston of the hydraulic press master cylinder body piston rod blank main cylinder device that Fig. 3 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2 to Fig. 3, the hydraulic press master cylinder body piston rod blank main cylinder device that the utility model embodiment provides, comprise cylinder body 21 and piston 22, wherein, cylinder body 21 is divided into again cylinder bottom 211, cylinder barrel 212 and cylinder head 213, and cylinder bottom 211 is fixedly connected with cylinder barrel 212, cylinder barrel 212 is fixedly connected with cylinder head 213.Offer the through hole for installing piston 22 in the middle of cylinder head 213, piston 22 stretches in cylinder body 21 from cylinder head 213, and the centre of cylinder bottom 211 is provided with shoulder hole, and each aperture of shoulder hole is all less than the internal diameter of cylinder barrel 212.
After cylinder body 21 being divided into three parts, can to cylinder bottom 211, cylinder barrel 212 and cylinder head 213 are processed separately, during casting, can according to the actual service condition of these three parts, set different accuracy of manufacturing, manufacturing process etc., and if there is slag inclusion, during the casting defect such as pore or trachoma, only can scrap a part wherein, instead of as prior art, scrap whole cylinder body 21, namely this cylinder body 21 is after being divided into three parts, cost has been saved significantly in casting processing, consider that again three parts can be processed simultaneously, therefore, also improve manufacturing efficiency to a certain extent, shorten the manufacture cycle.
Preferably, above-mentioned cylinder bottom 211 and cylinder barrel 212 can be welded, and cylinder barrel 212 is welded with cylinder head 213, to form cylinder body 21.
In addition, in the utility model embodiment, also piston 22 can be divided into three parts, i.e. bar head 221, bar cylinder 222 and rod end 223, and be welded with bar cylinder 222 by bar head 221, bar cylinder 222 welds with rod end 223.
When piston 22 is installed, first bar head 221 is put into cylinder body 21, then the remainder of piston 22 is installed in cylinder body 21, and the relative sliding between piston 22 and cylinder body 21 will be ensured.
In order to reduce the scrappage of cylinder body 21 and piston 22, cylinder body 21 can be processed into 20 steel cylinder bodies, piston 22 is processed into 45 steel pistons.Because the master cylinder of the more existing spheroidal graphite cast iron of piston 22 of cylinder body 21 and 45 steel of 20 steel is lightweight, and structure smooth regular own, therefore, the machining amount needed when casting is few, and then shortens the manufacture cycle to a certain extent.
The hydraulic press master cylinder body piston rod blank main cylinder device that the utility model embodiment provides, the cylinder body 21 of its master cylinder is divided into three sections, i.e. cylinder bottom 211, cylinder barrel 212 and cylinder head 213, just can form cylinder body 21 after three being welded.This kind of structure, makes the cylinder body 21 of master cylinder when casting, and can avoid causing overall waste because of scrapping of a part; And segmentation manufacture, three parts can be cast simultaneously, shorten the manufacture cycle.Therefore, this hydraulic press master cylinder body piston rod blank main cylinder device has saved cost of production, shortens the manufacture cycle, and improves quality of product.
