Abstract : determining nip point is important for steady rolling section steel 文摘:確定型鋼軋制時(shí)軋件的咬入點(diǎn)對(duì)實(shí)現(xiàn)穩(wěn)定軋制有重要意義。
When work rolls become worn the roughness is diminishing creating slippage in the roll bite at higher speeds 工作輥磨損后,粗糙度遞減導(dǎo)致在較高軋制速度下進(jìn)料(咬入帶卷)時(shí)產(chǎn)生滑移。
Based on analyzing the intersection curve between the rolled - piece and roll , the method of determining the nip point is put forward 基于對(duì)軋件與軋輥截交線的分析,提出了在二維直角坐標(biāo)系中確定軋件咬入接觸點(diǎn)的方法。
Abstract : in this paper , the biting condition of cold rolling process for involute spline manufacture is built up . the condition provides guarantee for the success of the process , and provides basis for tool design and tryout 文摘:針對(duì)漸開(kāi)線花鍵冷搓成形工藝建立了咬入條件,從而為冷搓工藝的順利進(jìn)行提供了保障,也為冷搓模具的設(shè)計(jì)與調(diào)試提供了依據(jù)。
This system has the friendly windows for dialogue between person and machine , can draw and label the plan of each roll groove with the way of parameterization drawing , under the condition that giving the size of the rough blank the specifications of the finished product and the technical parameters of the roll , selecting the minimum consumption as the target function , adopting the optimization , adopting the boundary condition of the grip the strength of roll and the check of the power - generating . moreover , the plan can be outputted in the software of autocad 本系統(tǒng)具有友好的人機(jī)對(duì)話界面,可以在給定坯料尺寸、成品尺寸和軋機(jī)技術(shù)參數(shù)的條件下,以能耗最小為目標(biāo)函數(shù),采用最優(yōu)化方法,在滿足咬入條件、軋機(jī)強(qiáng)度校核、電機(jī)校核等邊界條件下優(yōu)化設(shè)計(jì)出最優(yōu)的孔型系統(tǒng),采用參數(shù)化繪圖方法將優(yōu)化設(shè)計(jì)結(jié)果繪制成孔型圖并進(jìn)行標(biāo)注,最終可以向autocad繪圖軟件輸出。
