我厂生产的东风-28拖拉机上有几种夹布胶管零件,规格如表1,采用整盘胶管切断制成。 最初在剪板机上切,效率不高,长度L~(+5)还常超差;(扭斜厉害)后改为先切成一米左右的条料,内用木蕊撑着上车床用片刀切,质量虽有保证,效率也不高。现改用模具来切断,提高了效率,保证了质量。模具结构如图所示。 主要由上、下模座、凹模座、刀片、凹模等组成。接头板6由螺钉、销钉将其固定
I plant the production of Dongfeng -28 tractors have several kinds of fabric hose parts, specifications, such as Table 1, the whole cut off the hose made. Initially cut in the cutting machine, the efficiency is not high, the length of L (+5) is often over-tolerance; (slanted) after the first cut into about one meter of the material, with wooden core propped on the lathe Sliced knife, although the quality assurance, efficiency is not high. Now switch to the use of mold to improve efficiency and ensure the quality. Mold structure as shown. Mainly by the upper and lower mold base, die base, blades, die and other components. The adapter plate 6 is fixed by screws and pins
