Cold heading is mainly used to manufacture bolts, nuts, nails, rivets and steel balls. The forging material can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy, etc., and the material utilization rate can reach 80 to 90%. Cold heading is mostly carried out on a dedicated cold heading machine, which is convenient for continuous, multi-station and automated production. On the cold heading machine, the processes of cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and trimming can be completed in sequence.
The bar material is automatically fed into a certain length by the feeding mechanism, and the cutting mechanism cuts it into a blank, and then is sent to the accumulation pressure forming and punching station by the clamp conveying mechanism for forming.
WBM is a bearing tool manufacturer, supplies carbide heading dies for Steel ball Industries from 1988.The die and Punch is used to head balls. Proper selection of Carbide Grade based on machine, material, cavity design, in order to achieve best cost performance.
