The invention discloses a passivation device for mechanical manufacturing, which includes a box body, a motor is fixedly connected to the bottom of the inner wall of the box, a telescopic rod is fixedly connected to one end of the motor, and a rotating mixing anti-adhesion device is arranged inside the box body Institutions involved in the field of passivation technology. This kind of passivation device for mechanical manufacturing is equipped with a rotating mixing anti-adhesion mechanism, so that it can pass the passivation pool back and forth, so that the circular grooves and arc-shaped grooves inside the passivation pool can be in and out of the passivation pool. While the passivated parts are in contact, the passivation solution inside is stirred and mixed in real time, so as to avoid the protruding stirring rod from touching the passivated parts during mixing and stirring, which will cause damage to the surface of the parts , By setting up a rotating mixing anti-adhesion mechanism, a large amount of passivation solution sediments are thrown and adhered to the surface of the arc-shaped plate by rotating centrifugal force to shake them off, so that the passivation solution has a higher uniformity.
Description
technical field [0001] The invention relates to the technical field of passivation, in particular to a passivation device for mechanical manufacturing. Background technique [0002] Passivation refers to the process of metal oxidation by strong oxidants or electrochemical methods to make the surface inactive, that is, passivation. It is a method to transform the metal surface into a state that is not easy to be oxidized and delay the corrosion rate of the metal. In addition, the phenomenon of an active metal or alloy in which the chemical activity is greatly reduced and becomes a noble metal state is also called passivation. At present, when passivating and mixing the inside of the passivation tank, the centrifugal force of stirring often leads to uneven distribution of chromium ions in the passivation tank, which tend to adhere to the inner wall of the passivation tank, and precipitate crystals will appear at the bottom of the tank, resulting in The passivation of the work...
