[0002] Cold heading machine is a special equipment mainly used for batch production of nuts, bolts and other fasteners. The multi-station automatic cold heading machine uses cold heading to head discs or bars. It automatically heads various hexagonal nuts and taps them, and then heads standard hexagonal nuts with corner punching. Several processes can be completed by one machine. The cold heading stations are arranged horizontally and have the characteristics of accurate positioning, stable operation and convenient maintenance. It is suitable for balls and bars to be fed through roller transmission. It is a special equipment for manufacturers to mass produce nuts. The multi-station automatic cold heading machine is a special equipment for the production of hexagonal nuts and some non-standard parts.
