Abstract
The invention discloses an energy-saving bending roller cylinder block. The energy-saving bending roller cylinder block comprises a bending roller block body, a piston rod and a gland, wherein a piston section is arranged on the piston rod, and a rod end chamber oil mouth and a non-rod end chamber oil mouth are formed in the bending roller block body; an abrasion resistant cylinder sleeve is detachably installed in an oil cylinder hole of the bending roller block body in a sealed mode, the piston rod is arranged in the inner hole of the abrasion resistant cylinder sleeve, the gland is arranged at the rod end of the piston rod in a sleeved mode, installed in the abrasion resistant cylinder sleeve and fixed to the bending roller block body, a piston seal assembly is arranged between the piston section and the inner hole of the abrasion resistant cylinder sleeve, and a piston rod seal assembly is arranged between the gland and the piston rod. The detachable abrasion resistant cylinder sleeve is additionally arranged in the bending roller block body, machining precision of the inner hole is improved, and the service life of the bending roller cylinder block is prolonged; only replacement of the cylinder sleeve is needed in the case that the bending roller cylinder block must be maintained, so maintenance cost is reduced, and shutdown maintenance time is shortened.
Description
Technical field
The present invention relates to a kind of bending cylinder block, relate in particular to a kind of energy-saving bending cylinder block.
Background technique
Bending cylinder block is one of vitals of cold rolling mill.In cold rolling production, bending cylinder block presses work roll and support roll, prevents that work roll and support roll from skidding when unloaded and startup; If the pressure of bending cylinder block is increased, can realize the effect of positive and negative roller, for plate shape and the quality of controlling steel plate, be all vital.
Existing bending cylinder block ubiquity cylinder inner bore wear resistance is poor, and working life is short, once and in cylinder body wearing and tearing, just whole cylinder body all need to be changed, maintenance expenses is high, engineering time is long.
Summary of the invention
The object of the present invention is to provide a kind of energy-saving bending cylinder block, it has long service life, maintenance expenses is low and engineering time is short characteristics, to solve the problems referred to above that in prior art, bending cylinder block exists.
For reaching this purpose, the present invention by the following technical solutions:
A kind of energy-saving bending cylinder block, it comprises the roller bending block body, piston rod and gland, be provided with the piston section on described piston rod, offer rod chamber hydraulic fluid port and rodless cavity hydraulic fluid port on described roller bending block body, wherein, removably be sealed and installed with wear resisting cylinder jacket in the oil har opening of described roller bending block body, described piston rod is arranged in the endoporus of wear resisting cylinder jacket, the rod end that described gland the is enclosed within piston rod wear resisting cylinder jacket of packing into is fixed on the roller bending block body, be provided with the piston seal assembly between described piston section and wear resisting cylinder jacket endoporus, be provided with the rod seal assembly between described gland and piston rod.
Especially, described piston seal assembly comprises at least one seal groove on the surface that is opened in the piston section, in described seal groove, is provided with seal ring.
Especially, described rod seal assembly comprises some seal grooves that are opened on the gland endoporus, in described seal groove, is provided with seal ring.
Especially, offer at least two seal grooves on the outer wall of described wear resisting cylinder jacket, in described seal groove, be provided with seal ring.
Beneficial effect of the present invention is; compared with prior art described energy-saving bending cylinder block is set up detachable wear resisting cylinder jacket in the roller bending block body; improved the machining accuracy of endoporus; extended the working life of bending cylinder block; in the situation that must keep in repair; only need to change cylinder sleeve and get final product, reduced maintenance cost, shortened fault power time.
