What are the types and characteristics of screw cold heading machines?

Main equipment and characteristics of screw cold heading machine: one die and two punches cold heading machine: mainly used for small head deformation, simple product, low cost and high production efficiency. Such as rivets, pins, countersunk screws and slotted screws.

Two-die three-punch cold upsetting machine: mainly used for multi-step special-shaped parts and short rod parts with large head deformation.

Three-die three-punch cold upsetting machine: mainly used for hexagon-head bolts, cylindrical hexagon-head bolts and relatively simple products.

Two-die four-punch cold upsetting machine: mainly used for multi-step special-shaped parts and short rod parts with large head deformation.

Four-die four-punch cold upsetting machine: mainly used for products with large and complicated head deformation, such as hexagonal (twelve-angle) blue-faced bolts.

Five-die and five-punch cold upsetting machine: mainly used for special-shaped parts with large head deformation and complex shape.

Six-die six-red cold upsetting machine: mainly used for special-shaped pipe fittings with large and complicated head deformation.
