The invention refers to an automatic control device for a bending-machine intended for the production of concrete reinforcement loops of bar or wire material,in which all the bending processes necessary to the production of a loop as regards the lengths of the individual sides of the loop,the sense of direction of the individual bending processes and the amount of the angle of bend,as well as the process of severing the finished loop from the bar or wire material can be present.
Bending-machines are known which have sequence control mechanisms which establish a quite definite succession of actions of the individual tools of the bending-machine.For presetting the length of travel by which the bar material to be bent must be advanced between the successive bending processes in order to obtain the desired lengths of the sides between bends,as well as for presetting the amount of each angle of bend,in the known control mechanisms drums are employed which are driven by step-switch mechanisms and along the circumferences of which stops or micro-contacts are arranged,so that they can be moved and fixed.These drums,after each operating cycle of the bending-machine move forward in a partially step-wise manner,so that the next stop or the next micro-contact arrives in the operating position.
Contacts or stops which,in dependence upon the feed stroke covered by the bar material to be bent,or upon the angle of pivot turned through by the bending tool,are moved along a track running parallel with the associated drum,cooperate with the stops or microcontacts on the drums.As soon as associated stops engage,or associated microcontacts coincide,the preset feed stroke of the bar has been covered or the bending tool has turned through the preset angle of pivot,and the next working step provided for in the sequence control is automatically introduced.
These known control mechanisms suffer from several disadvantages.The setting and fixing of the stops or microcontacts along the drums which are often not readily accessible is difficult,and the supposed number of possibilities for the desired setting is limited by the available circumference of the drum.But above all because of the relatively large number of setting processes,rational production of different loops is not possible.

这项自动控制设备的发明可以使XX(这个机器不懂,作用是让固体弯曲或者形成某个固定形状)从取材自棍状或线状物上生产出的产品得以确定的强化,环状物的各个侧面的长度都必须通过此设备来确定.各个弯曲过程的方向和弯曲角度的控制,以及从棍状和线状物体切断已经完工的环形物得以实施.
XX被公认为可以独立完成一系列控制技巧,它们通过实施一套非常明确的行为来实现.为了预调整工作进程以及获得预期的弯曲之间侧面的长度,在连续的弯曲过程间隙必须提前提供将被弯曲的杆状材料,并且预设各个弯曲角度.使用的控制机械鼓状物受步步切换的设置控制,则整个圆周的每个停顿和微小控制都可以得以调整,它们也可以移动或者固定.这些鼓状物在该机器向前移动各个部分的逐步方式的操作循环之后,使下一个停顿或者下一个微小接触出现在操作位.
当被弯曲材料覆盖那一划,或者当弯曲工具平转枢轴角度经过的时候,停顿或者接触就会出现,沿着与相关的鼓状物平行的轨迹移动,在鼓面上合作完成停顿和微小接触.一旦相关的停顿出现或者相关的微小接触相符,预设的杆状物的划动就会被覆盖或者弯曲工具会平转预设的枢轴角度,并且下一个工作步骤出现,实现了自动生产的一系列控制.
这个控制机械有一些不足之处,沿着鼓状物的停顿或者微小接触的设置和固定会比较困难,并且由于鼓面圆周大小的限制,预期设置的目标数目很有限.而且尤其因为相关的大量设置进程,该机器不可能合理的生产不同大小圆状物.
