非标角钢冷轧矫直机(矫直部分) 摘 要 矫直机是轧制车间必不可少的重要设备，而且广泛用于轧材作坯料的各种车间，如汽车、船舶制造厂等。 矫直机矫直钢板时,由于长度方向发生塑性变形,导致钢板与矫直辊速度差可达到3%因而产生附加扭矩以往的整体传动易导致接轴和齿轮损坏,同时当矫直辊与钢板产生速差时,钢板打滑现象会损伤表面,为了避免这些现象的发生,矫直辊尽量采用单独传动或分组传动,同时还可用于控制张力。关键词：NON-STANDARD ANGLE IRON COLD STRAIGHTENING MACHINE ABSTRACT Straightening machine is important and indispensable equipment in rolling workshop, and it is also used in a variety of workshops rolled to billets, Such as automotive, ship manufacturing, etc.. When straightener is used to Straighten plates, due to length of the plastic ,its deformation is occurred, resulting in the velocity difference between steel plate and straightening rolls, just like the 3% rate,thereby creating additional torque. The overall drive past easily leads to damage between axis and gear.At the same time when the speed of straightening rollers and steel production is different, the steel skidding may damage the surface, in order to avoid the occurrence of these phenomena, straightening roll as far as possible use separate drive or group drive ,at the same time it can also be used to control the tension. Firstly, through the understanding and learning of the principle of straightening, the number of the straightening rollers are determined by a large number of calculations. Then according to the shape of the workpiece , the contour of the straightening roller and the entire design of the structure of straightening roller is determined. The second is the design of the power transmission and guide devices. Taking into account the traditional and modern design, this issue puts the straightening roller into straightening machine platform with uniform and independent distribution. In this design, it not only make the separate drive of straightening rollers possible, but also to transform into modern mainstream straightener by changing the distance between each straightening roller at any time. KEY WORDS: Straightening machine, different from the roll, straightening rolle 目 录 前 言 1 第1章 绪 论 2 §1
