我厂新到一台 DK3220型线切割机床,在使用过程中发现,由于丝架下边的导电轮及排丝轮的槽子很窄,又多在暗处,视线不太好,往往钼丝很不容易都挂在槽子内,经常出现钼丝跳槽现象,影响穿丝速度,给加工带来不便。针对这种情况,我们对下导电轮及排丝轮进行了改进,大大提高了穿丝速度,克服了钼丝跳槽现象。经过一年来的使用,效果很理想。本机导电轮及排丝轮是使用的同一张图纸。因此只需要把导电轮的厚度尺寸加宽H,H 宽度尺寸略大于丝架的槽宽尺寸1～2mm,考虑到加宽 H 尺寸的同时,导电轮及排丝轮的重量也随之加大,所以在加工导电
I plant a new DK3220-type wire-cutting machine tools, found in the course of use, as a result of the wire frame below the conductive wheel and the row of wheels is very narrow trough, and more in the dark, the line of sight is not very good, often very molybdenum wire Easy to hang in the trough, often appear molybdenum wire jump phenomenon, affect the threading speed, to the processing inconvenience. In response to this situation, we have improved the lower conductive wheel and the row of round, greatly improving the threading speed, to overcome the phenomenon of the migration of molybdenum wire. After a year of use, the effect is very satisfactory. This machine is the same conductive roller and yarn wheel is the same drawing. So only need to widen the thickness of the conductive wheel size H, H width slightly larger than the width of the wire frame width 1 ~ 2mm, taking into account the widening H size at the same time, the conductive wheel and the winding wheel weight also will be increased , So in the processing of conductive
