圓盤剪切機(jī)設(shè)計(jì)
摘 要
現(xiàn)在各國工業(yè)迅猛發(fā)展,鋼鐵企業(yè)是國民經(jīng)濟(jì)的主要支柱,它的發(fā)展?fàn)顩r很大程度上可以反映出國家的實(shí)力?,F(xiàn)代鋼鐵冶金業(yè)發(fā)展的一個(gè)著眼點(diǎn)就是在對鋼材的處理速度。圓盤剪切機(jī)就是其中的一臺(tái)重要設(shè)備。
圓盤剪切機(jī)通常設(shè)置在精整作業(yè)線上,用來將運(yùn)動(dòng)著的鋼板的縱向邊緣切齊或切成窄帶鋼。根據(jù)其用途可分為兩種類型:剪切板邊的圓盤剪和剪切帶鋼的圓盤剪。
本文中對圓盤剪切機(jī)的設(shè)計(jì)計(jì)算是在對鞍山鋼鐵集團(tuán)公司冷軋廠1700橫切機(jī)組大量調(diào)研的背景下進(jìn)行的。通過對圓盤剪切機(jī)及相關(guān)設(shè)備結(jié)構(gòu)進(jìn)行了深入了解,并從材料力學(xué)、動(dòng)力學(xué)和經(jīng)濟(jì)學(xué)的角度出發(fā),對圓盤剪切機(jī)的主傳動(dòng)系統(tǒng),壓下系統(tǒng)、側(cè)間隙調(diào)整機(jī)構(gòu)進(jìn)行了設(shè)計(jì)。重點(diǎn)包括電動(dòng)機(jī)的計(jì)算選取、軸和齒輪的設(shè)計(jì),以及其他傳動(dòng)裝置和執(zhí)行機(jī)構(gòu)的設(shè)計(jì)等,同時(shí)對部分主要零部件進(jìn)行了強(qiáng)度校核。本次設(shè)計(jì)的改進(jìn)點(diǎn):首先,在徑向間隙調(diào)整機(jī)構(gòu)連桿機(jī)構(gòu),其二,側(cè)向間隙調(diào)整增加自鎖裝置。其三,寬度調(diào)整采用行星齒輪減速機(jī)。最后增加了測速機(jī)構(gòu)。本圓盤剪切機(jī)可普遍用于橫切機(jī)組、酸洗機(jī)組等。

The disc alligator shears design
Abstract
The industry of various countries develops rapidly now, the steel, as the main pillar of industry, its development can reflect the national strength to a great extent. Modern steel metallurgy industry one starting point that develop in to processing speeds. Disc shears is an important equipment among them.
Disc shear machine set up in finishing production line. It usually uses to cutting neat the movement steel plate longitudinal edge and cut the strip into narrow one. It can be divided into two kinds according to its use: disc shears of cut stencil plate’s side and disc shears of cut strip.
The disc shears design calculation is taken in makes the massive investigation to the ANSHAN steel group Cold-rolling mill 1700 transverse cutting aircrew as the background. We have thorough understanding to the disc shears and the correlation equipment. We had very designed to the main transmission system, depress the system and gap adjustment organization, we are carry on these designs from the materials mechanics angle, dynamics and economic. The main content including electrical machinery selection, Axis and gear design, Implementing agency design and so on, and the same time, we make the optimized improvement and the intensity examination to the major parts. This design improvement spot: First, in radial clearance adjusting mechanism link motion gear, second, backlash adjustment increase self-locking installment. Third, the width control uses the planet gear speed reducer. Finally increased has measured the fast organization. This disc shears may use in the transverse cutting unit, the acid pickling unit generally and so on.
Key words: Disc shear, strip, depress the system, the intensity examination
