Rocky bolt rolling forming machine could be used to make the rocky bolt in batch and fully automatically; A rock bolt , is also called the roof bolt, it is a long anchor bolt, for stabilizing rock excavations, which may be used in tunnels or rock cuts. It transfers load from the unstable exterior to the confined (and much stronger) interior of the rock mass. There are many type, here I will take a random pipe type for example:
And for the material thickness and pipe diameter range, we could make accoding to the custtomer requirments. And for the accessory, we could also make for you.
Here are some pictures for your reference:
Based on the demand of customer, we made the machine for your reference.
The bolt machine parameters for your reference:

Feartures of High strength coal mine roof bolt expansion shell rolling forming machine:
1.As the material thickness of bolt reaches
4.0mm, we use the gear box as transmission method.
2.As the machine need accuracy, we can make sure 100%.
3.For cutting edge, we can make online.
4.Working speed could reach 25m/min.
5.Fully automatic production line from decoiler to runut table.
For the bolt pad making, we could use this type machine:
