Description

Technical Field

[0001] The invention relates to the technical field of sealing component production and cutting, in particular to a cutting device for sealing component production. Background Art

[0002] A seal is a material or part that prevents fluids or solid particles from leaking between adjacent mating surfaces and prevents external impurities such as dust and moisture from invading components inside machinery and equipment, ensuring the sealing performance inside the mechanical structure, thereby protecting the normal operation of the equipment and preventing mechanical failures or safety accidents. The seal industry occupies an important position in the national economy and is widely used in defense, chemical, petroleum, coal, transportation, and machinery manufacturing industries. The production of seals is common in cutting and processing rubber sleeves. As a continuous material form, rubber sleeves have good continuity and plasticity, which is easy to cut and process. This continuity enables rubber sleeves to reduce material waste during processing, improve material utilization, and facilitate the production of seals of various shapes and sizes.

[0003] However, in the existing seal production process, since the material usually has a certain elasticity, it is easy to undergo elastic deformation due to the pressure and friction of the tool during the cutting process. This deformation may lead to inaccurate cutting dimensions and affect the assembly and use of the seal. At the same time, stress concentration will occur at the contact point between the tool and the seal. If the stress exceeds the strength limit of the material, it may cause local material damage or cracks, further affecting the cutting accuracy. Due to the influence of elastic deformation and stress concentration, the surface of the seal after cutting may become uneven and the roughness may increase, which not only affects the appearance quality of the seal, but may also reduce its sealing performance.
