Abstract
A wear-resisting sealing structure for a pressing cylinder belongs to the technical field of hydraulic pressure equipment comprising a cylinder lid provided with annulus slots in its inner wall, a converse 'V' form sealing ring arranged at the annulus slots, a supporting ring matching with the sealing ring provided at the downside of the sealing ring, a pressing ring matching with the sealing ring provided at the upside of the sealing ring. Upside section of the supporting ring appears a converse 'V' form or a '*' form. Downside of the pressing ring is provided axially with a converse 'V' form groove. The annulus slots in the inner wall of the cylinder lid is composed of step slots arranged at the inner top of the cylinder lid and step formed fixing ring connected with the up end of the lid. The multilayer stacked sealing ring has a lager radial dimension than that of pressing ring and of supporting ring. The fixing ring is composed of several holed step formed pressing pieces. The utility model has great sealing performance and wearing-resisting property, and easy assemblage and striping.
Description
Technical field
The utility model belongs to the hydraulic equipment technical field, particularly a kind of Pressing Cylinder Wearproof Hermetically-sealed Construction that can be used for cubic hinge press.
Background technique
Cubic hinge press is synthetic to be a key Design point with the piston nose of cylinder pressure and the sealing of cylinder cap matching part, and existing press ante-chamber sealing is O RunddichtringO of design on piston, seal ring both sides design plastics back-up ring.Environment is relatively poor in the course of the work owing to piston nose, and a lot of dusts are arranged, and seal ring is serious wear in reciprocal running, but the assembling magnitude of interference that adds the O RunddichtringO few (compression of rubber is few), the life cycle of seal ring is short, and oil leakage phenomenon often takes place, and often needs repairing.
The model utility content
The utility model purpose is to provide a kind of cubic hinge press Pressing Cylinder Wearproof Hermetically-sealed Construction of good seal performance.
For reaching above-mentioned purpose, the utility model adopts following technological scheme: a kind of Pressing Cylinder Wearproof Hermetically-sealed Construction, comprise cylinder cap, and the cylinder cap madial wall is provided with circular groove, the reversed V-shape seal ring is installed in the circular groove, be provided with below the seal ring support ring adaptive with it, above be provided with the pressure ring adaptive with it.
Cross section, support ring top be reversed V-shape or
Shape; The pressure ring bottom is axially arranged with inverted v-shaped groove.
Circular groove on the cylinder cap madial wall is made of with the stepped shape retainer ring that is connected with the cylinder cap upper end the stepped slot of cylinder cap inside top setting.
Seal ring is the multilayer stack and is provided with, and the seal ring radial dimension is greater than pressure ring and support ring radial dimension.
Retainer ring is made up of a plurality of stepped shape compressing tablets with holes.
The utility model adopts circular groove is set on cylinder cap, wherein the design of multi-layer sealed circle is set, and is easy to processing.The black box that is stacked by pressure ring, reversed V-shape seal ring and support ring is set in the circular groove, and the surface of contact of seal ring and piston is big, good sealing effect, and wear resistance is strong; But the assembling magnitude of interference of seal ring is big, and after date can be adjusted pressure ring when using one section, increases the sealing distortion again, fills up ring wear, and easy to adjust reliable, life cycle can prolong more than five times.In the using process, in the inner part reverse V-shaped seal groove and high-voltage oil cavity communicate, and oil pressure can make the further radial dilatation of seal ring, and sealing effect is better.Circular groove on the cylinder cap madial wall is made of with the stepped shape retainer ring that is connected with the cylinder cap upper end the inboard stepped slot that is provided with of cylinder cap, can put into the cylinder cap inner side slot to black box earlier during installation, the retainer ring button thereon, fixes with housing screw again, and is easy to loading and unloading.Retainer ring can be designed to overall structure, also can be designed to the branch body structure that multi-disc constitutes.
