What should I do if there is an interruption in the feeding of my concrete nail making machine?

Feed interruption is generally caused by three reasons. First, the raw material (such as wire) surface roughness, there is a bend, stuck in the feeding channel; Second, the feeding roller is badly worn, and the friction between the wire is insufficient, can not be pushed stably; Third, the feeding motor failure, power output is not stable. To solve the problem, first stop the machine to check the raw material, pick out the unqualified wire; then check the wear of the roller, and replace the worn roller in time; if there is a problem with the motor, you need to ask a professional to overhaul or replace the motor, to restore the normal operation of the feeding system.

How to solve the problem of irregular head shape after concrete nail forming？

The irregular shape of the nail head may be caused by wear and tear of the forming mould, improper installation or uneven forming pressure. Long-term use of the mould, wear and deformation of the internal cavity will lead to deviation in the shape of the head of the nail; the mould is not calibrated in place when installed, and the uneven force during forming will also cause this problem; in addition, the pressure system of the moulding machine is faulty, and the pressure will fluctuate, which will also affect the effect of the moulding. To deal with this problem, it is necessary to check the wear of the moulds regularly and replace the worn moulds in time; recalibrate the installation of the moulds to ensure that the position is accurate; and overhaul the pressure system to check the faults and repair them, so as to ensure the stability of the pressure.

What are the reasons why concrete nails do not have strong welds and tend to fall off?

There are three main reasons why the welding is not firm. First, the welding current, voltage and other parameters are not set reasonably, the heat is not enough to cause the nail cap and the nail rod is not fully integrated; Second, the welding head surface has an oxidised layer, welding slag and other impurities, which affects the heat conduction; Third, the part to be welded has oil, rust, which hinders the welding. To solve the problem, it is necessary to re-tune the welding parameters according to the material and specifications of the nails; regularly clean the welding head to remove impurities; clean the surface of the nails before welding to ensure that the welding part is clean and improve the welding quality.

Concrete nail making machine cuts off large size error, nails are not the same length, how to deal with it?

Cutting size error is big, may be cut off the knife wear, feed positioning inaccurate or cut off the machine drive system failure caused. Cutting tool edge wear, cutting will produce deviation; feed positioning device loose or sensor failure, can not guarantee that each feed length is consistent; cut off the machine transmission components such as belt, chain loose, will make the cutting power transmission is not stable. The solution is to replace the worn cutter in time; calibrate the feeding positioning device, check the working status of the sensor; check the transmission parts, adjust the belt, chain tightness, to ensure that the cutting size is accurate.

The anti-corrosion effect of concrete nails after surface treatment is poor and they are prone to rust, how can this be improved？

Poor anti-corrosion effect may be the surface treatment before cleaning is not thorough, nail surface residues of oil, rust, affecting the adhesion of the coating; may also be the coating thickness is not uniform, too thin place is easy to be corroded; may also be the surface treatment process parameters are not appropriate, such as galvanising temperature, time control is not accurate. When dealing with it, it is necessary to strengthen the pre-treatment process to ensure that the surface of the nails is thoroughly clean; adjust the spraying or plating equipment to ensure that the coating thickness is uniform; optimise the surface treatment process parameters, strictly control the temperature, time, etc., to improve the anti-corrosion performance.

What could be the reasons for excessive vibration and abnormal noise when the concrete nail machine is in operation？

The machine vibrates too much and the noise is abnormal, it may be that the foundation of the equipment is not solid, such as loose ground bolts; it may also be that the transmission parts are worn out and loose, such as poor gear meshing and damaged bearings; it may also be that the motor is faulty, such as rotor imbalance. To solve the problem, first check the foot bolts, tighten the loose bolts, reinforce the equipment foundation; then check the transmission parts, replace the gears, bearings, etc., which are badly worn; if there are problems with the motor, it is necessary to overhaul the motor, adjust the balance of the rotor, and reduce the vibration and noise.

How to troubleshoot the control system of a concrete nail production machine?

Control system troubleshooting can start from three aspects. Firstly, check the power supply to see whether there is unstable voltage, loose wiring and other problems; secondly, check the sensors, controllers and other electrical components to see whether there is damage, poor contact phenomenon, can be judged by measuring the resistance, observing the indicator light, etc.; and finally, check the control program to confirm whether the parameter settings are correct, and whether there is any procedural loophole or error. For complex faults, need to use professional testing instruments and technical personnel to assist in troubleshooting and repair.
