Umbrella head roofing nail production line

What is the umbrella head roofing nail production line?

The umbrella head roofing nail production line refers to the process of manufacturing umbrella head roofing nails. This process includes a series of machines to ensure the mass production of high-quality umbrella head roofing nails, such as the cap making machine, the roofing nail making machine and galvanization equipment, etc. The umbrella head roofing nail is used in outdoor installation to fasten shingles, asbestos tile, plastic tile, etc. The roofing material decides the length and diameter of roofing nails to achieve a better installation effect. There are three types, including smooth shank roofing nail, ring shank roofing nail and screw shank roofing nail. The smooth shank roofing nail has a smooth shaft, so the other two types are more stable and endurable than the smooth shank roofing nail.

What are the main machines in manufacturing umbrella head roofing nails?

The wire drawing machine, cap making machine, roofing nail making machine, nail polishing machine and galvanization equipment are essential elements in the process of transforming the raw material steel wire into umbrella head roofing nails. The wire drawing machine uses different drawing dies to reduce the steel wire to the desired diameter. The cap making machine punches the steel plate to form nail caps. The roofing nail making machine installs the nail caps and cuts the cold steel wire into roofing nails. The nail polishing machine makes nails shiny and smooth. And the galvanization equipment is used to galvanize nails to protect against corrosion.

How to produce umbrella head roofing nails?

The production process of high-quality umbrella head roofing nails includes wire drawing, cap making, roofing nail making, nail polishing, galvanization and packaging.

Wire drawing

Wire drawing is the first step to making umbrella head roofing nails. The wire drawing machine draws the raw material steel wire Q195/SAE1008 to the needed diameter. And the difference from the normal wire drawing machine is that this requires a twisting device to make the steel wire spiral, the purpose of which is to help the roofing nail grip the wood well.

Cap making

There is no order for nail cap making and wire drawing. These two steps are all preparations for making umbrella head roofing nails. The cap making machine is designed to make roofing nail caps. The raw material of the nail cap is the steel plate, and the nail cap is formed by punching in the steel plate through a punch press.

Roofing nail making

The drawn wire is then fed into the roofing nail making machine and the roofing nails are placed in the storage box of the roofing nail making machine. The roofing nail making machine is used to make umbrella head roofing nails. The working principle of the roofing nail making machine includes four steps. First, put the drawn wire rod on a wire reel, then feed it to the roofing nail making machine and put the nail caps in the storage box. Second, when the nail mold grips the drawn wire, the roofing nail caps drop to the pin punch and are individually punched onto the nail shank. Next, the feeding box sends the steel wire forward, then the nail cutter cuts the nail according to the set length and cuts the nail point. Finally, the umbrella head roofing nails are down the conveyor belt into the collection box.

Nail polishing

After the roofing nail making, the nail polishing machine polishes the umbrella head roofing nails. The nail polishing machine polishes umbrella head roofing nails with saw dust in the polishing barrel to remove any sharp edges on the nails and give the nails a smooth and shiny surface.

Galvanization

Next, the umbrella head roofing nails are galvanized by the galvanization equipment to ensure the roofing nails are corrosion resistant. Since roofing nails are meant to withstand years of rain, snow, sun, etc., galvanization is a must to keep the roofing nails from rusting. This galvanization equipment adopts electro-galvanizing technology. First, wash the polished nails with water and put them into a drum containing a zinc salt electrolyte solution for galvanizing. An electric current is then applied, causing the zinc ions in the solution to be reduced and deposited onto the surface of the nails. This process produces a uniform thin zinc layer. Next, put the galvanized nails into buckets of different liquids, and perform water washing, light extraction, water washing and passivation in sequence. Finally, after washing with hot water again, put the nails in the spin dryer to dry the nails. The galvanizing of the roofing nails is over.

Packaging

The umbrella head roofing nails are packaged in cartons following the galvanization process. Different cartons are packed with different sizes and weights of roofing nails, such as 1 kg, 5 kg, 20 kg or 25 kg per carton.
