冷軋管機(jī)發(fā)展中有關(guān)技術(shù)問(wèn)題的討論

Discussion on Technical Issues Concerning Development of Cold-rolling Pipe Mill

摘要: 對(duì)二輥式、多輥式冷軋管機(jī)發(fā)展中的幾個(gè)關(guān)鍵技術(shù)問(wèn)題進(jìn)行了理論探討和比較;對(duì)冷軋管機(jī)主參數(shù)系列、機(jī)架行程長(zhǎng)度、曲柄轉(zhuǎn)向、同步齒輪分度圓直徑、同步齒輪模數(shù)、單雙回轉(zhuǎn)送進(jìn)及多輥式冷軋管機(jī)軋輥數(shù)目的選取等進(jìn)行了分析和比較;提出了設(shè)計(jì)建議。還推薦了一種新型的軋管機(jī)平衡系統(tǒng)即雙偏心塊齒輪平衡系統(tǒng)及多輥式冷軋管機(jī)機(jī)頭圓定心結(jié)構(gòu)。

Abstract: The discussion addresses several key issues respective to development of two-high and multi-high cold-rolling pipe mills,focusing on relevant theoretic analysis and comparisons concerning selections of such data as the main parameter series,mill block stroke,the crank turning,synchronous gear indexing wheel diameter and modulus,single or dual rotary feeding as well as roll number of the multi-high mill.Based on the result,counter-measures are proposed.Moreover,the author recommends a newly-developed rolling mill balancing system,i.e.,the dual eccentric gear balancing system and a new structure of the centering system for the multi-high mill head.
