Cold heading forming of high-strength bolts

Usually the bolt head is formed by cold heading plastic processing. The cold heading forming process includes cutting and forming, single-station single-click, double-click cold heading and multi-station automatic cold heading. An automatic cold heading machine performs multi-station processes such as stamping, heading forging, extrusion and diameter reduction in several forming dies.

(2) During the transfer of short-sized blanks from the previous station to the next forming station, the fasteners with complex structures are processed to improve the accuracy of the parts.
(3) Each forming station should be equipped with a punch return device, and the die should be equipped with a sleeve-type ejector device.
(4) The structure of the main slider guide rail and process components can ensure the positioning accuracy of the punch and the die during the effective use period.
