研究板材冲压变形时的金属流动的规律,确定合理的工艺参数,在金属表面印制坐标网格是必要的试验手段。若用接触照像法在金属表面印制坐标网格,需要经过甩胶、制板、感光、腐蚀等多道工序才能完成。此种方法在比较小的板料上制作还不太困难,但要在大型板料上的局部印制坐标网格就困难了。我们研制的金属表面印图机,就能解决这个难题。并且它还可以在金属块、柱等的表面印制图形。该机是以电蚀法为原理印制坐标网格的,由:①电器设备;②电蚀液;③图形模板三部分
It is necessary to study the law of metal flow during sheet metal stamping deformation, determine the reasonable process parameters and print the coordinate grid on the metal surface. If using contact photographic method to print the coordinate grid on the metal surface, it needs to go through many processes such as glue rejection, board making, light exposure and corrosion. It is not too difficult to make such a method on a relatively small sheet, but it is difficult to print a coordinate grid locally on a large sheet. We developed the metal surface printing machine, you can solve this problem. And it can also be printed on the surface of metal blocks, columns and other graphics. The machine is based on the principle of galvanic printing coordinate grid, by: ① electrical equipment; ② electro-etching liquid; ③ graphics template three parts
