驅(qū)動(dòng)電機(jī)斜置在鋸機(jī)底座上，通過(guò)傘齒輪及主傳動(dòng)軸帶動(dòng)鋸片，鋸片由液壓裝置鎖緊在傳動(dòng)軸上。鋸片進(jìn)鋸由液壓驅(qū)動(dòng)，進(jìn)鋸速度根據(jù)鋸切阻力由比例閥調(diào)節(jié)。當(dāng)軋件斷面較大、鋸切阻力高時(shí)，進(jìn)鋸速度慢，反之，進(jìn)鋸速度塊。

The driving motor is inclined on the base of the saw machine, and the saw blade is driven through the bevel gear and the main drive shaft, and the saw blade is locked on the drive shaft by the hydraulic device. The sawing saw is driven by hydraulic pressure, and the speed of the saw is adjusted by the proportional valve according to the cutting resistance. When the section of the rolled piece is large and the cutting resistance is high, the speed of the saw is slow, and conversely, the speed block of the saw.

開(kāi)口式機(jī)架由機(jī)架底座和上橫梁組成。

開(kāi)口式機(jī)架是型鋼車(chē)間常見(jiàn)的一種機(jī)架形式。這種機(jī)架的優(yōu)點(diǎn)是制造簡(jiǎn)單，裝卸、換輥方便。其缺點(diǎn)是強(qiáng)度和剛度較低，軋輥輥跳值較大，影響產(chǎn)品精度，故只適用于大型軋機(jī)。

The open frame is of the frame base and the upper cross beam.  

The open frame is one of the most common forms in the steel workshop. The advantages of this frame are simple manufacturing, loading and unloading, and convenient for roll change. Its disadvantage is that its strength and stiffness are low, the roll roll value is larger and the precision of the product is affected, so it is only suitable for large rolling mill.

連續(xù)加熱爐連續(xù)加熱爐包括推鋼式加熱爐、步進(jìn)式爐、轉(zhuǎn)底式爐、分室式爐等連續(xù)加熱爐，但習(xí)慣上常指推鋼式爐。連續(xù)加熱爐多數(shù)用于軋制前加熱金屬料坯，少數(shù)用于鍛造和熱處理。

It is named according to the varieties of rolling, the type of rolling mill and the nominal size. The principle of "nominal size"

For rolling mills, they are named after the gear ring and the pitch diameter of the herringbone gear.

楔橫軋工藝的基本原理是，將加熱后的棒材送入兩個(gè)同向旋轉(zhuǎn)的帶有楔性凸起的模具中間，棒材在模具的帶動(dòng)下，作與模具反向的回轉(zhuǎn)運(yùn)動(dòng)，同時(shí)材料發(fā)生徑向壓縮變形和軸向延伸變形，從而成形階梯軸類(lèi)零件。

The basic principle of the cross wedge rolling process is to send the heated bar into the middle of two same revolving moulds with wedge-shaped protrusi. The rod is driven by the mold to make the reverse rotation movement with the mold. At the same time, the material has radial compression deformation and axial extension deformation, thus forming a staircase type part.
