The invention discloses a gear
electroplating method adopting
wax protection on a non-plated part. The gear
electroplating method comprises the following steps: pre-checking; washing with
gasoline;
drying by blowing; performing
drying; insulation protection is conducted, the gear is preheated in a
drying box at the temperature of 60-70 DEG C for more than 30 min, the temperature is kept all the time, the gear is taken with a clean fine sand glove, the gear is coated with
wax liquid in a rolling mode for 5-6 times till the thickness of a
wax layer is 3 + / -0.2 mm, the first-time
waxing temperature is 170 DEG C, the second-time
waxing temperature is controlled to be 150 + / -2 DEG C, cooling and
waxing are conducted in sequence, and when the wax layer just coated on the gear in a rolling mode is not transparent and white, the gear is taken out.
Waxing is stopped, the boundary part is trimmed through a self-made bamboo blade after natural cooling to the
room temperature, and the waxed surface cannot be collided or pinched forcefully in the subsequent operation; removing oil; mounting and hanging; electrolytic
degreasing; washing with cold water; weak acid
pickling; washing with cold water; cyaniding
copper plating; recycling and washing; washing with cold water; acid
copper plating; recycling and washing; washing with water; dewaxing is conducted; drying by blowing; and drying. The method is easy and convenient to operate, good in insulation effect, high in temperature adaptability, high in applicability,
environmentally friendly and economical.
