Cold Heading

Abstract

The term ‘cold heading’ is a generic term describing the continuous manufacture of parts by upsetting from wire or wire rod in coil form. The operation is carried out on specially designed horizontal presses equipped with means of feeding wire from coil, straightening, cutting to length and thence finally forming in one or more blows. The presses range from relatively simple machines equipped with a single punch and die, forming the part in a single blow, to complex multi-die/punch machines with integral means for transferring the part through the die sequence.
