1. The torque setting of this batch is too large, resulting in wire slippage. At this time, as long as the torque is adjusted, it can be guaranteed that the lock will not slip next time.
2. It is caused by the mismatch between screws and nuts. Generally it may be caused by screw mixing. Just look at the screws in the hopper and eliminate the mismatch to solve the problem of thread slipping.
3. The electric batch head is seriously worn, which may be caused by the long use time of the electric batch head. Replacing the electric batching head can solve this problem.
