W11-6×1600卷板機設(shè)計要求
該卷板機結(jié)構(gòu)形式為三輥對稱式,上輥在兩下輥中央對稱位置通過錐齒輪傳動作垂直升降運動,通過主減速機的末級齒輪帶動兩下輥齒輪嚙合作旋轉(zhuǎn)運動,為卷制板材提供扭矩。規(guī)格平整的塑性金屬板通過卷板機的三根工作輥(二根下輥、一根上輥)之間,借助上輥的下壓及下輥的旋轉(zhuǎn)運動,使金屬板經(jīng)過多道次連續(xù)彎曲,產(chǎn)生永久性的塑性變形,卷制成所需要的園筒、錐筒或它們的一部分。該卷板機主要有一個上輥、兩個下輥、機架及驅(qū)動電機傳動機構(gòu)等部分組成。
本設(shè)計要求對該型卷板機做總體設(shè)計和上輥、下輥和機架等機構(gòu)做結(jié)構(gòu)設(shè)計。
原始數(shù)據(jù):1.最大卷板厚度:6mm
2.最大卷板寬度:1600mm
3.卷板速度:7.52m/min
4.滿載卷板最小直徑:∮350mm
5.上輥直徑:∮160mm;下輥直徑:∮150mm;兩下輥中心距:210mm
6. 板材屈服極限:245MPa
技術(shù)要求:
1. 該機結(jié)構(gòu)形式為三輥對稱式,上輥在兩下輥中央對稱位置作垂直升降運動,通過絲桿螺母蝸桿轉(zhuǎn)動而獲得,兩下輥作旋轉(zhuǎn)運動,通過減速機的輸出齒輪與下輥齒輪嚙合,為卷制板材提供扭矩;
2. 卷板機運行要平穩(wěn)、可靠,要有良好的整體結(jié)構(gòu)剛度;
3.結(jié)構(gòu)整體要有較高的強度和抗沖擊性能。
摘 要
卷板機是一種將金屬板材彎卷成筒體、錐體、曲面體或其他形體的通用成型設(shè)備,廣泛應(yīng)用于石油、化工、機械制造等領(lǐng)域。近年來, 隨著煤炭需求量的增加,市場對礦用提升機、輸送機、支架等礦用設(shè)備的需求,無論從質(zhì)量和數(shù)量上,都有了更高的要求,滾筒等弧形或圓筒形礦用產(chǎn)品的需求量也日益加大。
卷板機是一種將金屬板材卷制成筒形、弧形或其它形狀工件的通用設(shè)備。根據(jù)三點成圓的原理,利用工作輥相對位置變化和旋轉(zhuǎn)運動使板材產(chǎn)生連續(xù)的塑性變形,以獲得預(yù)定形狀的工件。
關(guān)于卷板機的分類,國外一般以工作輥的配置方式來劃分。國內(nèi)普遍以工作輥數(shù)量及調(diào)整形式等為標準實行混合分類,一般分為:
1)三輥卷板機:包括對稱式三輥卷板機、非對稱式三輥卷板機、水平下調(diào)式三輥卷板機、傾斜下調(diào)式三輥卷板機、弧形下調(diào)式三輥卷板機和垂直下調(diào)式三輥卷板機。
2)四輥卷板機:分為測輥傾斜調(diào)整式四輥卷板機和側(cè)輥圓弧調(diào)整式四輥卷板機。
3)特殊用途卷板機:有立式卷板機、船用卷板機、雙輥卷板機、錐體卷板機、多輥卷板機和多用型卷板機等。

ABSTRACT
Three-roller plate bending machine can bend plate to a special shape, such as colum,cone,camber and so on,which is widely applied to boiler manufacture,chenical industry and machine manufacture.Near years, colum,cone,camber can be used to internet ,belt conveyer,hoist foundation ect. In For this purpose,a class of Roll Machine has been developed in order to improve the productivity,decrease the work intensity and content the demand of the factory for plate coiling.
Machine is a roll of sheet metal bent to cylindrical, curved shape of the work piece or other common devices. According to the principle of three-point into a circle, making use of changes in the relative positions of roller and rotation so that producing a continuous sheet of plastic deformation, is scheduled for the shape of the work piece.
On the machine classification, in order to work abroad, the general approach to roll into the configuration. General domestic work and adjust the volume roll form, such as mixed as the standard classification, generally divided into:
???? 1) three-roll Rolling Machine: Including Three Roller Symmetrical Rolling Machine, Three Roller Asymmetrical Rolling Machine, horizontal three-roll machine down, tilt down Three Roller Rolling Machine, Three Roller downward arc Machine cut and the vertical three-roller machine.
???? 2) four-roll Rolling Machine: measuring roll is divided into four-roller tilt adjustment and side-roll Rolling Machine Arc-adjusted four-roller machine.
???? 3) special-purpose Rolling Machine: A Vertical Rolling Machine, Rolling Machine marine, twin-roll Rolling Machine, Cone Machine, multi-roll Rolling Machine and Rolling Machine, such as multi-purpose type.
KEY WORDS:rolling machine sheet metal molding equipment
