Description

Technical Field

[0001] This utility model relates to the field of plunger processing technology, and in particular to a damping ring matching device for the production of large plungers. Background Technology

[0002] The damping ring fits tightly against the gap between the plunger and the cylinder wall through elastic deformation, and automatically increases the contact pressure under hydraulic pressure to prevent high-pressure liquid from leaking into the low-pressure area.

[0003] When installing damping rings, they should not be pulled onto the plunger, as this may damage the ring. Instead, a heating ring is needed to heat the damping ring, increasing its ductility and thus its diameter, making it easier to fit onto the plunger. Due to thermal expansion and contraction, the ring will cool and then fit tightly onto the plunger. However, since plungers come in various models, multiple heating ring models are required for damping ring installation. Different sizes of heating rings are needed when machining different plunger models, making the installation process cumbersome and hindering efficiency. Utility Model Content

[0004] The purpose of this application is to provide a damping ring matching device for the production of large plungers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:
