Wire Nail Making Machine Line

The Nail Manufacturing Line is a complete system for processing steel wire rod into nails, and the whole process includes wire rod (raw material), wire drawing, nail making, nail polishing and nail cutter grinder.
1. Wire rod: generally, we recommend customer the Q235 wire rod, and it's diameter range is 1.8-6.5 mm, widely used for making common nail.
2. Wire drawing machine: it is a crucial piece of equipment in the metalworking industry, designed to reshape metal wires by reducing their diameter. This is achieved by pulling the wire through a series of dies, which gradually decrease in aperture size.
3. Nail making machine: Z94 series nail making machine can make wide range nails, with length from 25mm to 200mm, diameter from0.9mm to 4.5mm.
4. Nail polishing machine: it is for making the nail surface more smooth and bright.
5. Nail cutter grinder: this part is mainly used to maintain the knives of the above equipment
Finished wire nails are widely used in construction, carpentry, furniture manufacturing, crate and box fastening, electrical equipment assembly, home renovation, agricultural structures, infrastructure development, handicraft production, and various light industry assembly applications.

FAQs of Wire Nail Making Machines Line

Why does the feeding machine of nail production line have feeding jam?

First, wear and tear of mechanical parts: the conveyor belt, rollers and other parts of the feeder are worn out after long-term use, and the friction is reduced, which leads to poor material conveying.

Second, failure of the transmission system: the gears, chains and other transmission parts are loosened, misaligned, or insufficiently lubricated, which can’t stably transfer the power to make the material feeding intermittent jams.

Third, abnormalities of the control system: the sensors are out of order, and they can’t accurately detect the material Position, or control programme error, resulting in feeding rhythm disorder. It is necessary to repair the worn parts, adjust the transmission system, calibrate the sensors and optimize the control program.

Why are the nails produced by the nail moulding machine irregular in shape?

First, improper installation of mould: the mould is not accurately installed in place, there are angular deviations or uneven gaps, resulting in uneven force, skewed and deformed nails.

Second, serious wear and tear of mould: the mould cavities are worn out and the dimensions are changed after long term use, so that the nails produced can not conform to the standard shapes.

Third, unstable pressure: the hydraulic or pneumatic system of the moulding machine fails, resulting in the moulding pressure fluctuating and affecting the nail forming results. The pressure of the moulding machine is unstable, which causes the pressure of the moulding machine to fluctuate, affecting the effect of the nail moulding. It is necessary to recalibrate and install the mould, replace the worn-out mould in time and overhaul the pressure system.

Why is the nail welding machine weld easy to appear virtual welding?

There are three root causes of the problem of false welding.

First, wrong setting of welding parameters: the welding current, voltage, time and other parameters are not adjusted according to the material and specifications of the nails, resulting in insufficient welding heat, which can not be fully fused.

Second, pollution of the welding head: the welding head is used for a long time, the surface of the adherence of oxides, weld slag and other impurities, affecting the heat conduction and weld quality.

Third, the surface of the workpiece is not clean: there are oil stains on the welding part of the nails and rust, etc., preventing the welding material from combining with the workpiece. etc., hindering the combination of welding material and workpiece. It is necessary to re-adjust the parameters and clean the welding head regularly to ensure that the surface of the workpiece is clean.

Why is the length of nails cut by the nail cutting machine inconsistent?

First, knife wear: cutting tool edge wear, cutting resistance increases, resulting in cutting position deviation, nail length is not consistent.

Second, feeding positioning is not allowed: feeding positioning device loose or sensor failure, can not guarantee that each feeding length is accurate, affecting the cut off size.

Third, equipment vibration: cut off the machine running vibration is too large, the stability of the tool is affected, cutting accuracy is reduced. Need to timely replace the worn tool, calibrate the positioning device, troubleshooting and solve the vibration source of the equipment.

Why does the coating flake off from the nail surface treatment equipment?

Coating flaking is caused by a variety of factors.

First, incomplete pre-treatment: the oil, rust, etc. on the surface of nails are not completely removed, the coating is not sufficiently bonded to the surface of nails, and it is easy to peel off.

Second, improper treatment process: such as galvanising temperature, time control is not accurate, the coating crystalline structure is bad, reduce adhesion.

Third, uneven coating thickness: unstable pressure of spraying equipment or clogging of nozzle, resulting in partially too thick or too thin coating, and the thick part is easy to crack and peel off. It is necessary to strengthen the pre-treatment process, optimise the processing parameters and regularly maintain the spraying equipment.
