Design Calculation of Drive System of Walking Beam Cooling Bed for Seamless Steel Pipe

摘要: 介紹用于無(wú)縫鋼管生產(chǎn)的齒條步進(jìn)式冷床的結(jié)構(gòu)、組成及工作原理。分析冷床運(yùn)動(dòng)過(guò)程中的受力狀態(tài)，探討冷床升降機(jī)構(gòu)及橫移機(jī)構(gòu)傳動(dòng)系統(tǒng)的設(shè)計(jì)計(jì)算方法。根據(jù)該計(jì)算結(jié)果設(shè)計(jì)的冷床傳動(dòng)系統(tǒng)可保證齒條步進(jìn)式冷床低速啟動(dòng)和高速平穩(wěn)運(yùn)行，無(wú)縫鋼管落在定齒梁上時(shí)低速停止，并可使無(wú)縫鋼管在圓周方向上均勻冷卻，避免發(fā)生彎曲，確保無(wú)縫鋼管表面質(zhì)量。

Abstract: Described in the article are the sturcture, the compostion and the working principle of a walking beam cooling bed for seamless steel pipe production.The load condition of the cooling bed in motion is analyzed, and the design calculation method of the drive system of the cooling bed lifting and transfering mechanism is discussed.According to the results of the calculation, the designed cooling bed drive system can guarantee low speed start-up and high speed stable operation of the walking beam cooling bed.When a seamless steel pipe drops on the fixed rack, it will stop at low speed, which allows uniform cooling on circumference of the pipe, avoids curving and ensures its surface quality.
