Description

一种新型卷取机卷筒 技术领域
本发明涉及一种新型卷取机卷筒。
背景技术
卷取机用来将带钢卷取成卷，并在卷取机和轧机之间建立张力。工作时，卷筒准停在初始位置，带钢头部进入钳口，钳口夹紧，卷筒旋转，开始卷取。目前，钳口大多采用液压结构形式，工作时，钳口液压缸无杆腔进油，推动活塞及牙板将带钢头部夹紧，有杆腔进油，活塞及牙板退回，将带钢头部松开。该钳口结构复杂，加工难度大，夹紧效果也不太理想，且由于卷取张力作用，活塞与缸体之间的密封、缸体与扇形板之间的密封容易损坏，漏油现象较为严重，一旦漏油，将严重影响带钢表面质量。现有的卷筒基本为有缝卷筒，在卷取薄板时，容易在薄板表面形成压痕，影响外观质量。
发明内容
针对上述缺陷，本发明的目的在于提供一种结构简单，能够对高强度板材进行折弯，减小回弹量，便于下卷，夹持力度强的一种新型卷取机卷筒。
为此本发明所采用的技术方案是：
包括卷筒轴，卷筒轴的径向方向上均匀设有三个凹槽，所述凹槽内设有楔形块一，所述楔形块一上方设有与楔形块一相互配合的楔形块二，卷筒轴的中心处设有通孔，通孔内设有拉杆，拉杆一端固定连接有连接板，连接板与楔形块一固定连接，相邻楔形块二之间设有扇形板，其中一扇形板为钳口扇形板，钳口扇形板的上端面设有钳口，钳口扇形板两侧及扇形板通过螺栓与卷筒轴活动连接，螺栓与扇形板之间设有压簧，钳口设有与钳口扇形板固定连接的钳口板一，钳口底部设有导向槽，导向槽内设有楔形块三，楔形块三下方设有与楔形块三相配合的楔形块四，楔形块四与连接板连接，楔形块三上端设有与钳口板一相配合的钳口板二，所述钳口板二的夹持端面上固定设有钳口压条。
作为上述技术方案的进一步改进，所述楔形块二上端面两侧设有斜面，所述楔形块二张紧时与扇形板及钳口扇形板外表面形成无缝圆形。
作为上述技术方案的进一步改进，所述钳口板二下端面与楔形块三上端面通过燕尾槽结构连接。
作为上述技术方案的进一步改进，所述钳口板一的上端面为弧形面并与钳口扇形板的弧形面半径一致。
作为上述技术方案的进一步改进，所述钳口板二的夹持端面上设有嵌槽，所述钳口压条固定于嵌槽内。
作为上述技术方案的进一步改进，所述钳口压条的前端为刀尖状。
本发明的优点是：
本发明结构简单，通过采用本发明结构，能够对高强度板材进行折弯，减小回弹量，便于下卷，夹持力度强，张紧后楔形块二与扇形板及钳口扇形板外表面形成无缝圆形，不会对薄板表面形成压痕。
