The steel bar stripping and rolling straight thread connection technology is a new type of steel bar connection technology in construction engineering. The principle of the Automatic Bar Straight Thread Rolling Machine is to peel off a part of the longitudinal ribs and transverse ribs at the ends of the steel bars to be connected by cutting, then roll out the threads, and finally, connect them directly with the connecting sleeve on-site to complete the process of steel connection. The steel bar straight thread stripping and rolling machine is the key equipment to complete the processing of the steel bar straight thread head and realizes the steel bar straight thread connection process. It is mainly composed of a clamping mechanism, rib stripping and thread rolling mechanism, feed mechanism, cooling circulation mechanism, circuit control mechanism, and other parts.

Threading Machine Safety of Automatic Bar Straight Thread Rolling Machine:
1. Machine is made to thread and cut pipe or bolt. Follow instructions in Operator’s Manual on the machine uses. Other uses may increase the risk of injury.
2. Secure machine to bench or stand. Will keep the machine from tipping over.
3. Keep covers in place. Do not operate the machine with the covers removed. Exposure to moving parts may result in entanglement and serious injury.
4. Support long heavy pipe with pipe supports. Will prevent tipping of the machine.
5. Do not wear gloves or loose clothing. Keep sleeves and jackets buttoned. Do not reach across the machine or pipe. Clothing can be caught by the pipe resulting in entanglement and serious injury.
6. Clothing/gloves can be caught in moving parts. Fingers, hands, arms, or other body parts can be crushed or broken.
