Description
Technical Field
The invention relates to the technical field of surface treatment and processing of mechanical parts, and particularly provides a phosphating device for rust-proof processing of a gear.
Background
After the gear is manufactured and molded, the corrosion resistance of the gear can be improved by means of phosphating treatment, namely the rust resistance of the gear is improved, and meanwhile, the wear resistance of the surface of the gear can be improved.
Phosphating is a common metal surface treatment process, and refers to a process of forming a phosphate chemical conversion film through chemical and electrochemical reactions, the formed phosphate conversion film is called a phosphating film, namely, a layer of phosphating film is formed on the surface of a gear after phosphating, and the gear has good antirust performance due to the existence of the phosphating film.
In the process of phosphating treatment, a layer of thicker, uniform, fine and dense phosphating film which is the best state of the phosphating film can be obtained. In the actual phosphating process, the method can be specifically divided into dipping phosphating, spraying phosphating and brushing phosphating according to a phosphating treatment mode, wherein the dipping phosphating is the simplest, widest applicable temperature range and most common phosphating treatment mode, and the dipping phosphating refers to directly soaking a phosphating treatment object in a phosphating pool containing a phosphating preparation and in a heating state through a hanger or a carrier for phosphating treatment.
When the gears are subjected to dipping phosphating treatment, the traditional method comprises two methods, namely, one method is to mount a plurality of gears on a specially designed hanger one by one and then soak the gears in a phosphating tank for treatment, the other method is to directly stack a plurality of gears in a bearing frame for soaking phosphating, when the first method is adopted, each gear needs to be mounted on the hanger one by one, which is very troublesome, when the second method is adopted, all gears are randomly stacked and overlapped, and contact and overlap exist among the gears, so that a phosphating film with uniform density is difficult to form in the actual treatment process, and the final phosphating film forming quality is influenced; in addition, no matter which kind of mode is adopted to carry out phosphating treatment, a common problem exists, namely, the gear is basically in direct contact with phosphating solution, and in the actual phosphating treatment process, phosphating slag can be generated more or less in a phosphating pool in an unavoidable way, and some impurities can be brought into in the process that a phosphating object is soaked in the phosphating pool, and here, the phosphating slag and other brought-in impurities are collectively called as impurities, if the phosphating solution containing more impurities is in direct contact with the gear, after the phosphating treatment is finished, more impurities can be inevitably mixed in a phosphating film on the surface of the gear, so that the film forming quality of the phosphating film is influenced, and the antirust performance is reduced.
