The production efficiency is high, up to 300 pieces/min.

The maximum cold-rolled workpiece has a diameter of 48 mm. The cold rolling bolt process diagram is a typical process of cold head bolts. The multi-station nut automatic cold heading machine is a multi-station nut automatic cold heading machine. The bar material is automatically fed into the length by the feeding mechanism, and the cutting mechanism cuts it into a blank, and then the clamp conveying mechanism sequentially sends it to the accumulation molding and punching station for forming.  As far as the surface is concerned, the cold heading product looks better than the hot product, and the finish is good. In terms of use, the hot nut is generally harder than the cold heading product, and the strength is higher. For the user with high requirements, the material is different.
