Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, in particular to an auxiliary tool for manually cutting a sealing ring. Background Art

[0002] In mechanical manufacturing and assembly operations, sealing rings, as a key sealing component, are widely used in various occasions that require sealing, such as flange surfaces, pipe connections, etc. The sealing effect of the sealing ring directly affects the safety and stability of the entire system. However, in actual assembly operations, it is often necessary to manually cut the sealing ring to meet the needs of different sizes and shapes.

[0003] Traditionally, manual cutting of sealing rings mainly relies on scissors or similar tools, which are directly operated by workers. However, since sealing rings are usually made of elastic materials such as rubber, they have greater elasticity and surface smoothness, which brings great difficulties to manual cutting. During the cutting process, workers need to spend a lot of time and energy to fight against the elasticity of the material and ensure the accuracy and smoothness of the cutting. This not only reduces work efficiency, but also increases the labor intensity of workers.

[0004] In addition, due to the lack of effective fixing and auxiliary tools during the manual cutting of the sealing ring, it is difficult to ensure the cutting accuracy and consistency. The cross-section of the cut sealing ring is often not neat and smooth, which may cause misalignment and cracks during the subsequent cross-section bonding, seriously affecting the sealing effect of the sealing ring.

[0005] Therefore, it is necessary to provide a new auxiliary tool for manually cutting the sealing ring to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an auxiliary tool for manually cutting sealing rings.
