4.擰接機(jī)(Bucking machine)
采用型號(hào)為擰扣機(jī)：型號(hào)YNJG400，當(dāng)完成預(yù)緊的油套管放到擰扣機(jī)工位后，開始擰扣，編碼器記錄擰緊深度，PLC將接箍長(zhǎng)度，預(yù)緊深度，擰扣深度比較計(jì)算后得出J值；
Bucking machine model:YNJG400, put the pipe onto the bucking machine after pre-tightened, starts to make up the pipe, the encoder records the depth and PLC analyse and calculate the coupling length, pre-tightening depth and making-up depth to obtain the J value.
