1. The reinforcement thread head is butted in the reinforcement sleeve equipment, so that the thread of the reinforcement thread head can closely fit with the thread of the connecting sleeve under the action of the jacking force, so as to eliminate the thread gap.
2. The end face of the screw head and the end face of the connecting sleeve are pressed tightly to eliminate the thread gap. In this method, the screw head can not be pushed in the middle of the connecting sleeve, which can also achieve the effect of eliminating the thread gap.
However, attention should be paid to the difference between end face jacking and large-diameter self-locking at the thread tail. According to the above analysis, whether the blanking end face of the reinforcement is straight is an important process for the manufacturing quality control of the connecting wire head of rolled straight thread reinforcement, and it is also an important link that is easy to be ignored by most users. In addition to the blanking method, it should also be noted that the reinforcement should be straightened when the thread of the screw head to be processed is bent. The bending of the reinforcement will cause the incomplete thread out of tolerance of the thread of the reinforcement screw head, which will not only affect the appearance quality of the reinforcement screw head, but also have a certain impact on the bearing capacity of the butt head in serious cases.
