切割组件和用于形成玻璃坯的方法
摘要：
一种切割组件(1)设置有：支撑框架(5)；两个剪切构件(6)，其围绕各自的铰接轴线(8)相对于支撑框架(5)旋转，所述铰接轴线(8)相互平行；以及运动装置(19)，其用于使剪切构件(6)以往复旋转运动的方式、以相等的角度并且在相反的方向上旋转。剪切构件在后退静止位置和前进切割位置之间旋转，以便由至少一股熔融玻璃(3)形成玻璃坯(2)。运动装置(19)设置有：连杆和曲柄传动装置(22)；具有转子的旋转马达(20)，其驱动上述传动装置；以及控制单元(21)，其控制旋转马达并构造成使转子在两个行程结束角度位置之间、在相反的方向上旋转，行程结束角度位置对应于剪切构件(6)的后退静止位置。
摘要（英）：

A cutting assembly (1) is provided with a supporting frame (5), with two shear cutting members (6) revolving with respect to the supporting frame (5) about respective hinge axes (8), parallel to eachother, and with a movement device (19) for rotating the shear cutting members (6) with a reciprocating rotary motion, with equal angles and in opposite directions; the shear cutting members (6) rotate between a retracted rest position and an advanced cutting position to form a glass gob (2) from at least one thread of molten glass (3); the movement device (19) is provided with a connecting rod and crank transmission (22), a rotary motor (20) with a rotor, which drives such transmission, and with a control unit (21), which controls the rotary motor and is configured so as to rotate the rotor in opposite directions between two stroke-end angular positions, corresponding to the retracted rest position of the shear cutting members (6).
