【導(dǎo)讀】在三個方向變形。這個模型用來探究冷扎橫向偏移量控制系統(tǒng)的靈敏度對冷扎三。它最終揭示水平工作棍偏移量的影響最大，構(gòu)成了主要激勵。的改變了偏移程度。時，總軋制力會增大；當(dāng)減小軋輥直徑時，變形量又會增大。的材質(zhì)不均勻性減小，但是使產(chǎn)品的外形尺寸精度和平面度得不到保證。一些更先進(jìn)的軋機(jī)允許工作棍或支撐棍在水平面內(nèi)可控制的竄動，這是靠。軸承在與被軋板帶平行的平面內(nèi)移動實現(xiàn)的。圖1示意了這個過程。大擴(kuò)展并得到了廣泛印證。用數(shù)學(xué)方法描述每一種變形。Pawelski，Rasp和Rieckman證實了這種模型適。的，在這里，一對扎根反對稱拱形軸向竄動可以被聯(lián)系起來。單的一維形式，建立在與軋輥和軋輥?zhàn)冃味即怪钡姆较蛏?。分解以向量和線性的有特定意義的復(fù)數(shù)記錄和描述。軋輥的三維變形已由Stubbs給出，在這一節(jié)會詳細(xì)介紹。至于相互“纏繞”。其中，5A示摩擦力t引起的表面變形。Vh表示軋輥軸承的水平偏移量，在本文中不考慮這個量的影響。
【正文】 ition mounting, its mounting is simple and doesn’t need to maintain. Because it realizes shock absorbing way with a shock absorbing instead of steel springs superposition, so its advantages of rigidity, ageing resistance stable mechanical property shown in practice are beyond parison. Excellent properties of elastic damping materials enable disc shock absorber to satisfy big load shock absorbing requirement at very small volume so that effectively save design space. Its these good properties are also suitable for the anchor bolt shock absorbing etc. situations. High energy damping buffer Basic principle By the action of dynamic applied force, the fast insertion of piston will result in steep increase of friction between piston and damping material and piston rod is decided by moving speed, both are in direct proportion. The friction between solid sealing parts is decided by internal pressure, ., the larger internal pressure is, the larger friction is (the pressure is produced by pressing the volume of elastic material chamber). This shows that high energy damping buffer makes full use of pressibility and high viscosity of elastic damping medium, it converts instantaneous impact energy into elastic potential energy(produced by pressing medium)and thermal energy(produced by friction)and rapid release. High energy damping buffer made by using above principle has strong buffering ability, and its volume is small, weight is light, its buffering energy is 3 times of which rubber buffer had at same volume, the highest energy absorptivity can reach 85%. The advantages of products Compared with rubber buffer, high energy damping buffer can resist high temperature and corrosion, can suit adverse circumstances, it has strong rigidity and high shock strength, it works stably and has no ageing and failure phenomenon. Compared with traditional pneumatic buffer and air oil buffer or hydraulic buffer, it is easy to mount ,its structure is pact, volume is small, weight is light and service life is long, it doesn’t need daily maintenance. Because it has fewer sealing links and is not easy to damage, it is more suitable for high temperature circumstances in which pneumatic buffer and hydraulic buffer can not work, and it doesn’t need other plicated auxiliary devices, it has no air leak and oil leak phenomenon, it works stably and reliably. Scope of application High energy damping buffers have been widely applied in iron＆ steel industry and heavy machinery industry, such as: buffer for baffle plate and loop in rolling mill, for adjustable end stop, for limits of soaking hood and various moving machinery, lifting machinery etc. many places where buffering and guard are needed, the use result is very ideal, they can increase collision safety coefficient of equipment with the highest limit at a limited design space and guard the main equipment well.
