• All the solutions presented through this work are able to be used and a prototype has been built using the low cost solution, proving that it

properly programmed, allows a controlled movement of that holder which will accompany closely the evolution of the shear blade during the cutting process from one side to the other, avoiding deformations in the last portion of the cut strip when it is thin and wide. The following conclusions can be drawn:
• This technical device can be easily implemented in any shearing machine, new or already in service, does not needing changes in the
general arrangement.
• This is an innovative system, able to be easily commercialized
ming the control unit. The adjustment of the position is made in real-time by the control unit through a feedback position signal.
• The maintenance of the system was thought in order to keep it
simple;
• This novel device will help ensure the parallel arrangement between the front and the rear face of the cut metal strip which is the main
purpose of this work.
摘要金属剪切机是重型设备通常与低附加值由于少量技术设备公司。然而，这种情况可以通过设备设计者来改变创造力.分析一些具体的操作，可以观察到一些工具，当耦合到设备，应大幅提高切削加工生产率和最终产品质量。对于薄金属板的剪切过程，可以发现，在切割的最后阶段，切割材料重量是由一个小材料部分仍然需要削减暂停。这导致条尖变形，导致最终产品质量差，不能完全计划。这项工作是围绕这问题，研究最好的解决方案，开发一个新的工具，以避免缺乏板平整度削减后。一种新的设备的设计，能够很容易地连接到剪切机，继刀片运动全切作业。该系统是完全自动化的，由一个单一的切割指令给出的操作机器操作员。该系统允许制造公司增加每台机器的附加值，向客户提供先进和满意的解决方案，并对公司业务做出贡献持续性. 金属薄板剪切机英文文献和中文翻译(7):http://www.751com.cn/fanyi/lunwen_77335.html
