Introduction

Coil nail making machines play a crucial role in the construction and manufacturing industry by producing nails at a high volume and speed. These machines are designed to automate various steps in the nail production process, ensuring efficiency and precision.

Working Principle of Coil Nail Making Machine

Mechanical Feed System

The initial stage in a coil nail making machine involves a mechanical feed system. Wire is fed into the machine at a consistent pace. The system is equipped with precision rollers and sensors that maintain a feed accuracy of within 0.1 mm, minimizing wastage and ensuring uniform nail dimensions.

Wire Drawing Process

During the wire drawing process, the raw material is drawn through a series of dies. This process reduces the wire diameter to the required nail size. Precision in this stage is critical and the process typically achieves tolerances within ±0.05 mm, ensuring the strength and stability of the final product.

Nail Shaping

Nail shaping is accomplished through high-speed forming dies that shape the head and the point of the nail. The machine operates at speeds of up to 750 nails per minute, maintaining dimensional consistency and ensuring that each nail is formed to precise specifications.

Coiling and Welding

After shaping, nails are coiled and welded using a high-frequency welding process. This stage involves precise placement of nails onto a coiling pattern where each nail is spaced according to set specifications, usually within a 0.2 mm tolerance. Welding secures the nails in place, forming a coil, which is essential for the machine-fed nail guns used in the industry.

Final Inspection

The final stage involves rigorous quality control inspections. Automated laser inspection systems are utilized to ensure that every coil meets the necessary standards of length, bond strength, and spacing. Machines are calibrated to detect variations as small as 0.01 mm, ensuring consistent quality.
