Auto stamping agricultural machinery part

A surface treatment method for metal stamping parts used in agricultural machinery is provided. (1) weighing 9 12 weight parts of phytic acid, 7 8 weight parts of waterborne acrylic resin, 1 3 weight parts of sodium molybdic acid, 1 4 weight parts of nickel nitrate, 0.3 2 weight parts of nonylphenol polyoxyethylene ether, 1.2 3 weight parts of phenylnaphthylamine, 1.1 3.6 weight parts of alkyl trimethyl ammonium methacrylate, mixed, In 90 100℃ environment for 2.5h, that is, the surface treatment agent; (2) the 19 23 weight of the metal surface treatment agent and 60 65 weight of water mixed, the surface treatment liquid; (3) the surface treatment liquid temperature to 55℃, the metal stamping parts into the surface treatment liquid immersion 20 30min.

1)The first thing to look at the structure of the drawing piece, the shape of the drawing piece should be as simple as possible, symmetrical, as far as possible a drawing forming.

2)If the parts need to be drawn many times, on the premise of ensuring the necessary surface quality, the internal and external surfaces should be allowed to have traces that may be generated during the stretching process.

3)On the premise of ensuring assembly requirements, the side wall of the drawing part should be allowed to have a certain slope
