Most of the automatic six-axis stranding machines on the market today use electromagnetic brakes to control the parking position of the winding spindle, generally in the factory manufacturers will adjust the brakes in place, but after a period of operation, due to the frequent use of the brake and wear, there will be a brake noise, parking position deviation and other problems, if you need to wind a point winding foot or the need to cross the slot coil will appear deviation, causing the enameled wire can not be properly embedded in the slot, etc., so as a user to master certain processing methods will be more effective in the efficiency of the equipment.
First of all, let’s analyze the cause of the parking position is not accurate: first of all, the equipment parameters are not set properly, the winding machine in the normal operation of the spindle speed are very high, plus the skeleton load in this state there is a large rotational inertia of the spindle, if you need to run into a stop, then you need a buffer process, the process in the winding machine setting parameters corresponds to the stop jogging, there are many Many users do not pay enough attention to this parameter in use, resulting in insufficient number of buffer turns, and the spindle of the ring wrapping machine cannot stop at the specified position, and also increases the impact on the brake, which will affect the normal work of the brake if it runs for a long time and shorten its life greatly.
Secondly, the brake coil does not work properly, the coil does not work properly for a number of reasons, the input voltage of the equipment is unstable will cause the electrical components can not work properly, so the general winding machine has a rated working voltage, below and above the rated voltage will affect the normal work of the winding machine, and the brake pad will also affect the normal stopping of the winding machine, the working principle of the electromagnetic brake is that the coil The brake is a wear and tear part due to long time use, which will cause the friction plate to have different degrees of wear and tear, resulting in reduced braking torque.
Causes of inaccurate parking position there are many reasons for careful analysis in order to better deal with the solution, for the equipment parameters should be set according to the spindle speed and load to adjust the user, generally set to stop slow for 3-5 between, if the spindle speed is high and the load is relatively heavy in the case should increase the number of laps.
Usually before the start and operation of the equipment voltage should be checked to ensure that the equipment runs within the normal voltage range, too low and too high voltage will have an impact on the equipment, such as winding machine factory voltage instability should consider installing voltage stabilization devices; winding machine brakes are wear and tear components should be regularly checked, the normal operating condition of 2 years should need to be replaced, the friction plate spacing every 3 months need to be adjusted Once, the adjustment distance is 2-3mm.
