New Shearing by Moving Tool in In-plane Direction

与传统的剪切方法相比，提出了一种新的板料剪切方法，即在平面内移动刀具。进行了一系列试验，对新型剪切与常规剪切进行了比较。讨论了各种剪切方法的剪切力和剪切面。为了研究新剪切作用机理，采用有限元方法进行了数值模拟。讨论了刀具角度、间隙、板料厚度、剪切力和表面对成形的影响。将新型剪切与常规垂直剪切和重复垂直剪切进行了比较，并对剪切力和剪切面进行了检测。在新剪切器上施加较小的剪切力，获得了高精度的剪切面。当刀具角度为20~40度，间隙为0mm时，可获得优良的剪切面。当板材的厚度和材料确定后，计算剪切力。该报告将成为一个指标，并将根据该原理创建新的剪板机。在计算机数控上制作了原型剪切机，并将板料剪切成各种形状。因此，本研究为研制新型剪切机提供了可能。

The author proposed a new sharing method by moving tool in the in-plane direction for sheet metal compared with the conventional shearing. A series of experiments has been carried out to compare new shearing with the conventional shearing. Shearing force and shearing surface were discussed in various shearing methods. In order to investigate the mechanism of new shearing, simulations were carried out by the finite element method. The effects of tool angle, clearance, thickness of sheet, shearing force and surface have been discussed.The new shearing was compared with conventional and repetitive vertical shearing, and shearing force and surface were examined. The highly accurate shearing surface was obtained by small shearing force on the new shearing.When the tool angles are 20～40 degrees and the clearance is 0mm, excellent shearing surface isobtained. When the thickness and material of sheet metal are determined, shearing force is calculated. The report becomes an indicator and new shearing machine will be created with the principle. The prototype shearing machine was made on Computer Numerical Control and sheet metal shared to various shapes. Therefore new shearing machine is possible to be made by this study.
