1700冷軋機(jī)組卷取機(jī)設(shè)計(jì)
摘 要
卷取機(jī)是軋鋼成卷生產(chǎn)不可少的設(shè)備。保證卷取機(jī)順利工作對(duì)提高軋機(jī)生產(chǎn)率有很重要意義。冷軋機(jī)組中,卷取機(jī)用于卷取帶鋼成鋼卷。采用恒張力軋制,可以提高帶鋼質(zhì)量。
這次設(shè)計(jì)是1700冷軋機(jī)組卷取機(jī)設(shè)計(jì),其用于二機(jī)架冷軋機(jī)組中。首先,選擇卷取機(jī)的設(shè)計(jì)方案,并對(duì)設(shè)計(jì)方案進(jìn)行評(píng)述。由于冷帶鋼卷取張力大,采用四棱錐卷筒結(jié)構(gòu)。用液壓缸移動(dòng)斜楔進(jìn)行脹縮。將四棱錐體單獨(dú)加工裝在卷筒軸上,這樣改進(jìn),加工方便。當(dāng)錐體磨損后可以單獨(dú)更換。這樣,可以降低設(shè)備維修費(fèi)用。另外,四個(gè)扇形塊邊采用搭接技術(shù),防止卷筒脹開(kāi)后出現(xiàn)空隙,減少鋼卷局部壓扁,提高鋼卷質(zhì)量。去掉鉗口,采用助卷器卡緊帶鋼頭部,方便卸卷。
這次設(shè)計(jì),進(jìn)行主電機(jī)容量的計(jì)算和選擇。對(duì)斜楔進(jìn)行受力分析。計(jì)算帶鋼卷取過(guò)程中對(duì)卷筒的壓力并計(jì)算卷取軸彎曲強(qiáng)度,對(duì)傳動(dòng)齒輪進(jìn)行設(shè)計(jì)計(jì)算。對(duì)支承軸承進(jìn)行選擇和校核。采用合理的潤(rùn)滑方案、潤(rùn)滑方法和控制技術(shù),使卷取機(jī)技術(shù)先進(jìn),經(jīng)濟(jì)合理。強(qiáng)度足夠,有廣泛的使用價(jià)值,可用于酸洗、熱處理、鍍鋅和鍍鋅機(jī)組中。

1700 cold rolling unit coiler design
Abstract
The coiler is rolls steel the volume production not to be possible the few equipment. Guaranteed the coiler smooth work to enhances the rolling mill productivity to have the very vital significance. In the cold rolling unit, the coiler uses in the volume taking hoop Cheng Gangjuan. Uses the permanent tensity rolling, may improve the hoop quality.
The lap machine design of 1700 cold calendar units to used for two expansions of cold calendar units. First of all, choice the design project of lap machine, and carry on a comment towards it. In that the cold strips of lap tensile force is big, adopt four rib awls roll structures. Using the hydraulic cylinder to move the oblique wedge to expansion and contracting. It is convenience that processing four rib awls alone and setting on the roll. When the awls wear away, we can replace it alone. So it will reduce the maintenance costs of equipments. In addition, four fan-shaped piece side adoptions taking the lap laying lap work technique for avoiding appearing interstice after rolling expansion, reducing the steel roll parts to staving and enhancing quality of strips. To throw away the pliers , taking auxiliary roll machine to take the strips tightly for unloads strips conveniently.
The design of task is that calculation and choice of the main electrical engineering capacity. To analyze force of the oblique wedge. The calculation that the roll stress of taking strips and flection intensity of the roll shaft, and transmission gears. Choice and checking bearings. Taking reasonable project and method of lubricating ,and control technique, in order to the lap machine has advanced technique, reasonable economy ,the intensity is enough and extensive using value. It can be used for sour wash, hot processing, galvanization and galvanization units.
