项目摘要

A new flexible equipment using rolling mill and piano wires as versatile tools has been developed to achieve curvilinear slitting of thin sheet materials. In this process, various curves can be generated at the entrance of the rolls by using a computer controlled device which moves the piano wires to the width direction of the sheet. Slitting or cutting experiment is carried out using aluminium, copper, mild steel and stainless steel sheets, and the possibility and problems of this process are examined. As applications of this process, attempts are made to form curvilinear grooves on a sheet surface and to produce wire reinforced sheet metals.The experimental results show that the curvilinear slitting or cutting of sheet metals and foils can be easily performed by indenting piano wires into the thickness direction of a sheet with rolls. This cutting process can be successfully applied to plastic sheets, synthetic leather and drawing paper as well as sheet metals and foils. It is also shown that the production of plate with curvilinear grooves on its surface can be easily performed. Since wires with round, square and rectangular cross sections can be used as tools, grooves with various shapes are easily formed. It is also confirmed that when soft materials such as aluminium and plastic sheets are cut the flattening of the piano wire hardly occurs, and therefore the wires can be repeatedly used.

为了实现薄板材料的曲线分切，研制了一种新型的柔性设备，该设备以轧钢机和钢琴钢丝为万能工具。在此过程中，通过使用计算机控制的装置将钢琴钢丝移动到板材的宽度方向，可以在卷筒的入口处产生各种曲线。对铝、铜、低碳钢和不锈钢薄板进行了切分或切割实验，并对该工艺的可能性和存在的问题进行了探讨。作为该工艺的应用，尝试在板材表面形成曲线凹槽，并生产出线材增强的板材。实验结果表明，通过将钢琴钢丝压入板材的厚度方向，可以很容易地对板材和金属箔进行曲线切割或切割。这种切割工艺可以成功地应用于塑料板材、合成革和图纸以及金属板材和铝箔。试验还表明，表面有曲线凹槽的板材的生产是很容易的。由于横截面为圆形、方形和矩形的线材可以用作工具，因此很容易形成各种形状的沟槽。还证实，当切割软材料如铝板和塑料板时，钢琴钢丝几乎不会发生扁平，因此可以重复使用。
