1.1 traditional II molded cannula 04 are installed expenses of labour and are calculated
By at least needing 6 workman's mounting sleeves to be example, wherein stretch-draw teams and groups 4 people, monthly base pay 3000 yuan, monthly within 22 days, calculating everyone per day wage by production is 136.36 yuan.Transfer 2 people from the class of building in addition, monthly base pay 3400 yuan, everyone is at per day wage: 154.54 yuan.
To produce 1 group of SC300-500 type switch tie, often organizing SC300-500 type switch tie need of production 16 punching block, is that 16 cover punching blocks are installed II sleeve pipe overall process and on average needed 2.5 hours.The time that so often overlapping punching block mounting sleeve needs is:
2.5 hours/16 covers=0.16 hour
Working day by within 8 hours, to calculate can the punching block quantity of mounting sleeve be:
8 hours/0.16 hour=50 covers
The expenses of labour that a set of punching block of average out to installs II sleeve pipe is:
(136.36 yuan × 4 people+154.54 yuan × 2 people)/50 overlap=17.09 yuan
The installation expenses of labour that 1.2 traditional punching blocks install III molded cannula 5 calculates
By at least needing 6 workman's mounting sleeves to be example, because of reasons such as place restriction and production sequencings, all 6 people are all the class of building personnel, and everyone per day wage is 154.54 yuan.Be that 1 group of SC300-500 type switch tie punching block is installed III sleeve pipe overall process and on average needed 2.0 hours, so calculating according to 10.1.1 the expenses of labour that a set of punching block of average out to installs III sleeve pipe is: 14.48 yuan.
After 1.3 application nylon backstays 1, III molded cannula 5 installs expenses of labour calculating
