The Cold Heading Die, also called cold forming die, is a specialized die used in the process of cold heading, where a metal blank is formed into a part without heating. It is designed to form the head of a bolt, screw or other fasteners. The main die is the core component of the cold heading die, and it works together with the punch and the other components to produce the desired shape of the part.
Various types of cold heading machines are available, but for fastener production, it is common to find machines with one die two blow, up to five die six blow, and even more. The use of multi-die headers enables the production of more intricate parts in a single process, overcoming the limitations posed by the diameter ratio reductions.
In summary, the Cold Heading Die is an essential tool for the production of high-quality fasteners. With its high-quality materials, precision machining, and customizable features, it can meet the demanding requirements of various industries and applications.
Cold heading dies include various types such as straight hole dies, triangular dies, extrusion dies, trimming dies, and socket dies. The method of cold pressing, shrink fitting, or taper fitting is chosen for the carbide inserts based on the specific application or customer requirements. Similarly, the carbide heading dies come in different variations such as plain hole, pointing, extrusion, trap extrusion, hexagonal, hex extrusion, flat extrusion, and trilobular to cater to the production of various types of fasteners, screws, and bolts.
The Cold Heading Die is widely used in the production of bolts, screws, rivets, and other fasteners. It is suitable for use in high-volume production environments such as automotive, construction, and electronics industries.
