我厂革命工人在无产阶级文化大革命中,焕发出了冲天干劲,自己设计、制造了制动蹄磨床,如图1所示。在没有制动蹄磨床以前,一直是采用人工手摇的办法来加工的。工人劳动强度大,效率低,每天只能加工12付。现在采用制动蹄磨床,自动夹紧,自动松开,辅助时间少(t_辅=0.5分钟),加工时间短(t_工=2.5分钟),加工一付制动蹄只要3分钟,提高生产效率13倍。 In the Great Proletarian Cultural Revolution, the revolutionary workers in our factory glowed a glimmer of enthusiasm and designed and manufactured the brake shoes grinding machine, as shown in Figure 1. In the absence of brake shoe grinders, has been the use of manual methods to process. Workers are labor-intensive and inefficient, and can only process 12 fines per day. Now using brake shoe grinder, automatic clamping, automatic release, less auxiliary time (t_ auxiliary = 0.5 minutes), short processing time (t_ 工 = 2.5 minutes), processing a pair of brake shoes in just 3 minutes, Productivity 13 times.
