Abstract
The utility model relates to an improved structure of an oil cylinder body of a hydraulic machine. The improved structure comprises a cylinder barrel formed from a seamless steel pipe, and a combined cylinder body structure formed by a cylinder bottom fastened with one internal end of the cylinder barrel through a cylinder bottom lock nut, wherein a cylinder opening guide sleeve is fastened at the other end of the cylinder barrel; a sealing ring is arranged at one end part of a piston rod in the cylinder barrel; and a connecting lock nut for fixation with the body of the hydraulic machine is mounted on the outer part of the cylinder barrel in the axial direction. The improved structure of the oil cylinder body of the hydraulic machine can reduce the manufacture cost and machine loss and save processing hours, and is convenient for repairing the oil cylinder of the hydraulic machine; and as a result, the repair time is shortened and the repair cost is reduced.
Description
Technical field
The utility model belongs to hydraulic press manufacturing technology field, particularly relates to a kind of improvement structure of hydraulic press cylinder block.
Background technique
Along with the demand of various industries to hydraulic press constantly increases, the function of hydraulic press also constantly develops and reforms, and oil cylinder plays important effect as the main transmission part of hydraulic press in entire work process.Hydraulic press cylinder block in the known technology all is to adopt solid forging or split forging welded structure form to make; Though can improve the intensity of oil cylinder like this; Reduce the number of spare parts of oil cylinder, but exist following not enough: the forging blank price is high, the forging blank buying hour is long and hollow forging manufacture difficulty is big; Because cylinder block stays machining allowance big adding man-hour 35# cylinder forging blank, the minimum process surplus is monolateral 25mm, has so not only increased the operative workpiece man-hours requirement, and lathe and labour force consume greatly; In addition, very inconvenience of integrated type cylinder block maintenance.
Summary of the invention
The improvement structure of the hydraulic press cylinder block that the utility model provides a kind of and reduce manufacture cost for solving the technical problem that exists in the known technology, be convenient to process and keep in repair.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The improvement structure of hydraulic press cylinder block; It is characterized in that: comprise by the cylinder barrel of seamless steel pipe system and the combined type housing structure that constitutes through the fastening cylinder bottom of an end in cylinder bottom locknut and the cylinder barrel; The said cylinder barrel the other end is fastened with cylinder mouth guide sleeve; Piston rod one end in the cylinder barrel is provided with seal ring, cylinder barrel outside axially on be equipped with and be used for being fixedly coupled locknut with the hydraulic press fuselage.
The utility model can also adopt following technological scheme:
Be provided with a plurality of seal rings between said cylinder barrel and the cylinder bottom.
Said cylinder bottom locknut be connected locknut and all adopt seamless steel pipe to be processed into.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly adopt the cylinder barrel of seamless steel pipe system and the combined type housing structure that constitutes through the fastening cylinder bottom of an end in cylinder bottom locknut and the cylinder barrel; Not only can reduce manufacture cost and lathe loss, save machining period; But also can be convenient to the maintenance of hydraulic press oil cylinder, shorten engineering time and reduce maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, cylinder bottom locknut; 2, cylinder bottom; 3, connect locknut; 4, cylinder barrel; 5, piston rod; 6, connect locknut; 7, cylinder mouth guide pin bushing; 8, seal ring; 9, seal ring; 10, seal ring.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the improvement structure of hydraulic press cylinder block comprises the cylinder barrel 4 of seamless steel pipe system and the combined type housing structure that constitutes through the fastening cylinder bottom 2 of the interior end of cylinder bottom locknut 1 and cylinder barrel.The said cylinder barrel the other end is fastened with cylinder mouth guide sleeve 7; Be provided with seal ring 9 in the cylinder mouth guide pin bushing; Piston rod 5 one ends in the cylinder barrel are provided with seal ring 8; Cylinder barrel outside axially on be equipped with and be used for being fixedly coupled locknut 3 and being connected locknut 6 with the hydraulic press fuselage, in the present embodiment, said cylinder bottom locknut 1, connection locknut 3 and be connected locknut 6 and all adopt seamless steel pipe to be processed into.Be provided with a plurality of seal rings 10 between said cylinder barrel and the cylinder bottom.
The oil extraction of said cylinder barrel two cavity oil confession press oil cylinder, and with cylinder mouth guide sleeve place sealing acting in conjunction, to realize the to-and-fro motion of piston rod.
When maintenance, can be convenient to change sealing and maintenance, thereby save engineering time with piston rod from the cylinder bottom dismounting, reduce maintenance cost.
Said oil cylinder can be above the press upper beam directly takes out, in case oil cylinder when damaging, because of the press too small openings needs dismounting upper beam or slide block, thereby is saved engineering time and reduction maintenance cost.
