摘要: 安全裝置是連軋管機機械壓進式軋輥結(jié)構(gòu)必不可少的保護裝置,其合理性和工作穩(wěn)定性直接關(guān)系到連軋管機設備能否安全運行,也影響到設備維護成本和產(chǎn)品成材率。針對MPM連軋管機軋輥安全裝置存在的問題,改進了結(jié)構(gòu)設計,將安全臼的拉伸斷裂保護改進為剪切斷裂保護,取得了良好的效果。Abstract: Since the safety device functions as a necessary protective measure for the MPM with a mechanical feeding roll structure,its reasonableness and operation stability directly affect the safe running of the rolling mill proper and the maintenance costs for the equipment and the product yield as well.Addressing the existing problems of the MPM safety device,design modification of the structure thereof is conducted,involving changing the protective breaking type of the safety block from the original tensile failure into shearing failure.The operational effectiveness of the modified safety device is satisfactory
