长期以来,我们厂带锯机换锯条的松紧是采用手工摇转,每班大约换5-7次锯条,劳动强度大。在批林批孔运动推动下,我们厂广大职工,大搞技术革新活动,把过去用手摇转改革为电动装置,大大减轻了劳动强度。采用1瓩电动机,用蜗杆蜗轮减速传动二根丝扛旋转,推动上锯轮支持架上升和下降。然后在上锯轮支持架(升降台)后部份内侧固定一根扁铁(1)(长度根据实际需要,大约60-70厘米)。扁铁另一
For a long time, our factory band saw blade for the elastic band is hand-cranked, about 5-7 times each class saw blade, labor-intensive. With the promotion of Lin and Kong Kong campaigns, the vast majority of our staff and workers engage in technical innovation activities. In the past, they used hand-cranked reform as an electric device and greatly reduced their labor intensity. Adopt 1 瓩 electric motor, slow down with worm gear drive two wire carry rotation, promote the saw blade wheel support frame rise and fall. Then fix a flat iron (1) on the inner part of the rear part of the support frame (lifting platform) of the saw (about 60-70 cm in length according to actual needs). Another flat iron
