Abstract

The utility model discloses an assembling type hydraulic cylinder barrel and belongs to the field of steel pipe manufacturing and machining. The assembling type hydraulic cylinder barrel comprises a cylinder barrel body, a cylinder barrel end head flange, a cylinder barrel end tail flange, an end flange pressing cover, an end flange limiting semicircle block, a screw and sealing rings. Threads are arranged at the two ends of the cylinder barrel body. Correspondingly, mounting threads are machined on inner holes of the cylinder barrel end head flange and the cylinder barrel end tail flange. After the sealing rings are arranged at the two ends of the cylinder barrel body, the end flange pressing cover is arranged in the cylinder barrel body in a sleeved mode to exceed a thread section first, then the cylinder barrel end head flange and the cylinder barrel end tail flange are screwed in respectively, the end flange limiting semicircle block is clamped in, the cylinder barrel end flange pressing cover is aligned, and then the screw is tightly screwed for fixing. When the assembling type hydraulic cylinder barrel is used, assembling interchangeability is high, once a cylinder inner wall is abraded, the cylinder barrel body can be replaced quickly, other accessories can be used continuously, cost is saved, and the assembling type hydraulic cylinder barrel is suitable for a steel pipe water pressure expanding testing machine splitting-integrating die.

Description

Assembly type hydraulic cylinder
Technical field
The utility model relates to a kind of assembly type hydraulic cylinder, belongs to steel pipe manufacture and manufacture field.Be particularly related to a kind of hydraulic cylinder while being applicable to hydrostatic expansion of steel pipes testing machine deciliter mould.
Background technique
At present, also there is no special hydraulic cylinder at deciliter mould device of hydrostatic expansion of steel pipes testing machine, is generally to use the various cylinder tubes that substitute.Use the various cylinder tubes that substitute to have a shortcoming, because its operation frequency of deciliter mould device of hydrostatic expansion of steel pipes testing machine is large and Environmental Conditions is severe, cylinder liquid vulnerable to pollution, the easy corrosion garland of hydraulic cylinder inwall, make to cause in hydraulic cylinder and leak even and lost efficacy, make its function that loses deciliter mould, can only entirety scrap and heavily renew cylinder barrel, because cylinder barrel volume is larger, thereby cause unnecessary cost loss.
Model utility content
The utility model is to provide a kind of assembly type hydraulic cylinder, can overcome above-mentioned shortcoming, can solve the deficiency that causes hydraulic cylinder inefficacy entirety to be scrapped because of inwall corrosion garland.
The utility model solves the technological scheme that its technical problem adopts: assembly type hydraulic cylinder, comprise cylinder barrel main body, cylinder barrel termination flange, cylinder barrel end tail flange, end flange gland, spacing half nahlock of end flange, screw, seal ring, be processed with screw thread at cylinder barrel main body two ends, accordingly, cylinder barrel termination flange, cylinder barrel end tail flange also therein hole be processed with installation screw thread, install after seal ring at the two ends of cylinder barrel main body, first end flange gland is inserted in to cylinder barrel main body and exceedes thread section, then screw in respectively cylinder barrel termination flange and cylinder barrel end tail flange, snap in spacing half nahlock of end flange, to good cylinder barrel end flange gland, then tightening screw fixes.
When the utility model uses, assemble interchangeability strong, once inside wall of cylinder wearing and tearing can quick-replaceable cylinder barrel main body, other accessories can continue to use, cost-saving, are applicable to hydrostatic expansion of steel pipes testing machine deciliter mould.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: cylinder barrel main body 1, cylinder barrel termination flange 2, cylinder barrel end tail flange 3, end flange gland 4, spacing half nahlock 5 of end flange, screw 6, seal ring 7.
As shown in Figure 1, cylinder barrel main body 1 two ends are processed with screw thread, accordingly, cylinder barrel termination flange 2, cylinder barrel end tail flange 3 are also processed with installation screw thread at endoporus, install after seal ring 7 at the two ends of cylinder barrel main body 1, first end flange gland 4 are inserted in to cylinder barrel main body 1 and exceed thread section, then screw in respectively cylinder barrel termination flange 2 and cylinder barrel end tail flange 3, snap in spacing half nahlock 5 of end flange, to good cylinder barrel end flange gland 4, then tighten screw 6 fixing.
