The traditional manual graphite spraying method has the problems of uneven spraying, slow efficiency and unsafe spraying, which will affect product quality, dies working life, safety of operator. The automatic spray graphite machine can replace the workers' hand gun. In actual production, on the basis of not adding extra power source, it can spray graphite effectively and evenly inside the thickening mold, and make the forging process lubricative. Reduce forging defective rate effectively, amount of graphite usage and environmental pollution, so as to improve product qualification rate, extend dies working life and reduce production cost.
Spray graphite machine can be used with hot die forging press or electric screw press, employing single position, double positions or three positions, the rotating mechanism using two parallel rotation design.The spray graphite machine has the function of blowing scale and ejecting mould agent.The horizontal drive of spray graphite machine is driven by servo motor, and it has height adjustment function.
Spray graphite machine can be used for manual,automatic and semi-automatic production line to solve the problem of uneven ink spraying and uncontrollable ink quantity, too much ink on the die will make the liquid flow to hang. The process of spraying is to blow compressed air firstly, then spray graphite evenly, and finally blow compressed air to blow away the excess graphite.
There are many forms of spray graphite machine, sprinkler head can do circular track movement or according to the shape of forging track.
