Metal bolting making machine

Metal bolt is also called anchor (early name) “is contemporary coal mine roadway supporting the basic part, it is always used as roadway surrounding rock reinforcement together, the surrounding rock supporting their own. The metal bolting machine, we make it according to the tube roll forming machine principle. By this method, the bolts could be formed in batch from narrow strip to tube and then with the neck
Now anchor bolt is not only used in mine, also used in engineering technology, the slope, the tunnel, the main body of the dam reinforcement.
Base on the market needs, we developed new bolting making machine for batch and fully automatic production.

The Metal bolting making machine is composed by four separated machines:

Bolt roll forming machine, bolt ring welding machine, bolt neck punching machine and the washer punching machine.
