摘 要
卷取机是板带生产的主要设备，将其卷取成卷，便于生产、运输和储存。特点是近代冷轧向高速、大卷重方向发展，卷取机的重要性更为显著。
冷带钢卷取机按用途可分为大张力卷取机和精整卷取机两大类。大张力卷取机主要用于可逆轧机、连轧机、单机架轧机和平整机。精整卷取机则主要用于连续退火、酸洗、涂镀及纵剪、重卷等生产机组。
对张力卷取机的要求是有较高的强度、刚度以实现大张力卷取；卷筒张开后，应腀@晌桓鐾暾脑残危苑乐寡股四诓愦郑豢煽焖俑痪硗玻允视Χ嘀趾穸龋币蟾志肀砻嬷柿拷细卟⒂芯榔刂啤Ⅻbr>本设计应用于单机座冷轧机后，为四棱锥胀缩式卷取机，该机由电动机经减速器带动空心轴及套与其中的四棱锥，四棱锥由液压缸驱动，前后移动，从而胀缩套与其上的扇形板，使卷取的带钢缠紧或松开。棱锥角为7°30′。正常润滑条件下利用胀缩缸的工作压力来实现卷筒的自动缩径。
卷筒的薄弱环节是扇形块的尾钩，尾钩在棱锥轴轴向分力的作用下会产生很高的弯曲和剪切应力，易于疲劳所怀。本次设同时，正锥结构使主轴和胀缩缸的连接螺栓处于不利的受力状态。计的四棱锥卷取机采用倒锥式，显著改善了上述零件的受力状况，扇形块结构也得到简化。

Abstract
Coiler strip is the main production equipment, coiling into its volume, for the production, transport and storage. Cold is characterized by modern high-speed, Large re-direction, the importance of coiler more significant.
Cold strip coiler of the end-use can be divided into the tension coiler and finishing coiler two categories. The tension coiler mainly used for reversible mill, rolling mill, single-mill peace.
Finishing coiler is mainly used for continuous annealing and pickling, Tudu and Slitting, heavy volumes and other production units.
Tension coiler of the requirements is a higher strength and stiffness in order to achieve the tension coiling; reel open, should be able to become a complete circle, to prevent the injured lining strip; quick replacement volumes Extinguishers, to adapt to a variety of thickness, surface coil at the same time demand higher quality and corrective control.
This design applied to single blocks cold rolling mill, the pyramid expansion and contraction for the four-coiler, the aircraft by the motor reducer driven by the hollow shaft and with one of the four sets of pyramid, the four hydraulic cylinders driven by the pyramid, before and after the mobile , Which sets its expansion and contraction on the fan-shaped plate so that the take-up tight inside the strip or release. Pyramid angle of 7 ° 30 '. Under normal conditions of use of lubricating expansion and contraction of the cylinder pressure to achieve the automatic reel necking.
Reel is the weak link in the fan-shaped tail hook block, the tail hook in the pyramid shaft axial effort will have the effect of high bending and shear stress, fatigue easily by the Huai. At the same time, Cone is the main structure and the expansion and contraction of the tank bolt at a disadvantage in the state. Four of using inverted pyramid coiler cone, a significant improvement of the situation in parts of the force, fan-shaped block structure has been simplified.

Key words: coiler, the tension, the four pyramid, automatic necking, inverted cone.

随着科学技术的的发展，带钢生产目前大部分采用连续化成卷生产。在带钢
产过程中，需要采用带钢卷取设备来完成带钢缠卷、开卷及直头平展等工序，以便实现带钢生产连续化、机械化及自动化。可见带钢卷取设备是实现带钢生产连续化的重要设备之一。
用热连轧机生产带钢时，需要把热态（550~750℃）带钢卷缠成卷。目前大多数采用卷板机作为带钢卷取设备。卷板机一般安设在车间地坪以下，故亦可称为地下卷取机。为了使卷板机取得良好的卷取效果，一般在卷取过程中采用一定的卷取张力。
在卷取生产冷轧带钢时，采用冷带钢卷取设备来实现带钢的卷绕成卷。根据轧制工艺及卷取冷带钢要求，一般在卷取过程中采用较大的张力。目前大多数采用卷筒式卷取机作为冷带钢卷取设备。
本次设计的卷取机为四棱锥胀缩式卷取机。具体技术参数为： ; ; ; ; ; ;
在带钢连续精整机组（如退火、酸洗、剪切、涂层等）中，机组尾部要采用卷筒式张力卷取机来实现卷绕带钢；机组头部要求把成卷带钢展平，“展”和“平”
则分别由开卷设备和直头设备来完成。
综上所述，带钢设备应包括：
（1） 热态带钢卷取机
（2） 冷态带钢卷取机
（3） 冷态带钢开卷和直头设备
本说明书重点论述冷轧带钢卷取设备四棱锥胀缩式卷取机的结构、设计计算、结构及使用等问题。具体涉及传动系统的计算、径向压力的计算、液压缸的计算、棱锥轴及键的强度校核等。书中所述内容大部分取自国内外有关资料，望各位老师对书中的不妥之处，提出批评和指正。
