Description

Technical Field

[0001] The utility model relates to the technical field of buffer rings, and more specifically, to a hydraulic cylinder buffer ring. Background Art

[0002] The piston rod of the hydraulic cylinder has a certain mass and has a large momentum when it moves under the drive of hydraulic force. At the end of their stroke, when the piston rod enters the guide sleeve part of the hydraulic cylinder, it will cause a mechanical collision, generate a large impact pressure, and also generate a large hydraulic pressure, which will have a great impact on the main seal of the entire hydraulic system. In severe cases, it will affect the sealing and normal operation of the hydraulic system. When the commonly used hydraulic cylinder works under high pressure, a buffer ring will be installed at the front end of the piston rod main seal to filter the impact of high pressure on the main seal, so as to extend the service life of the main seal. The current buffer ring needs to be replaced after wear. When replacing, the front end of the hydraulic cylinder needs to be dismantled as a whole, which makes the replacement of the buffer ring cumbersome and inconvenient. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0021] Example:

[0022] The following is combined with Figure 1-3 The utility model is described in further detail.

[0023] See also Figure 1-3The utility model provides a technical solution: a hydraulic cylinder buffer ring, comprising a ring body 1, four pressure relief grooves 2 are provided at the bottom of the ring body 1, a cutout 3 is provided on the ring body 1, and the cutout 3 comprises a first cut surface 301 and a second cut surface 302. Through the joint action of the cutout 3, the first cut surface 301 and the second cut surface 302, the ring body 1 can be directly unfolded without removing the hydraulic cylinder, so that it is easy to replace. A fixing groove 4 is provided on the first cut surface 301, and a fixing block 5 is clamped in the fixing groove 4. The top of the fixing block 5 is fixedly connected to the second cut surface 302. Through the setting of the fixing groove 4 and the fixing block 5, it is convenient to connect and fix the first cut surface 301 and the second cut surface 302. The ring body 1 comprises a base 101 and a wear-resistant layer 102. The wear-resistant layer 102 is fixedly connected to the outer surface of the base 101. By setting the wear-resistant layer 102, wear is reduced, the wear-resistant effect of the base 101 is improved, and its service life is extended.

[0024] Specifically, four pressure relief grooves 2 are distributed in a cross-shaped manner at the bottom of the ring body 1. The pressure relief grooves 2 are designed in an I-shape as a whole. The inner walls of the pressure relief grooves 2 are chamfered transitions. The base 101 is made of polyetheretherketone.
