卷板機(jī)的規(guī)格型號(hào)許多,按卷板機(jī)的機(jī)械結(jié)構(gòu)和卷板機(jī)輥的數(shù)量區(qū)分,有三輥卷板機(jī)和四輥卷板機(jī)之分,按輥的驅(qū)動(dòng)辦法有機(jī)械式卷板機(jī)和液壓式卷板機(jī)之分,卷板機(jī)結(jié)構(gòu)相對(duì)簡(jiǎn)略,三輥傍邊有一對(duì)側(cè)輥和一根上輥,其中上輥能夠凹凸移動(dòng)。
四輥卷板機(jī)結(jié)構(gòu)相對(duì)雜亂,有一對(duì)側(cè)輥和一根上輥和下輥,這種卷板機(jī)本錢(qián)很高,但功能較好,卷制成道德量較好。各種卷板機(jī),作業(yè)原理都相同,經(jīng)過(guò)調(diào)劑上輥和側(cè)輥的相對(duì)位置,使板料在輥之間逐步曲折變形,用主軸的正回轉(zhuǎn)使板料在輥之間來(lái)回運(yùn)動(dòng)直至板料產(chǎn)生塑性變形。跟著輥的相對(duì)位置的不斷調(diào)劑,主軸不斷的往復(fù)正回轉(zhuǎn)運(yùn)動(dòng),板料的塑性變形量逐步加大,直至加工成契合懇求的圓弧或圓通型制品。
卷板機(jī)是一種將金屬板料彎卷成筒體、錐體、曲面體或其他形體的一 種專(zhuān)用鍛壓機(jī)械設(shè)備,廣泛用于汽鍋、造船、化工、金屬結(jié)構(gòu)及機(jī)械制造 職業(yè)。本課題的研討旨在改良老式卷板機(jī)的缺乏,行進(jìn)生產(chǎn)率、下降工人勞動(dòng)強(qiáng)度,滿(mǎn)意廠方對(duì)板料加工的生產(chǎn)需求。
Bending machine is a special equipment for forging machinery sheet metal bending into a cylinder, cone, or other body surface, widely used in boiler, shipbuilding, chemical industry, metal structure and machinery occupation. The purpose of this study is to improve the lack of the old type rolling machine, to improve the productivity, to reduce the labor intensity of the workers, and to satisfy the production demand of the factory.
