Abstract
The present invention is a kind of method for coating nylon on metal surface and device, can be in various difformity, and irregular coating nylon on metal surface layer, coating thickness is 0.15 to 2 millimeter, and process is simple, and is easy to operate, precision can reach 7 grades of tolerances, is a kind of desirable coating nylon process.
Description
The present invention relates to a kind of method for coating nylon on metal surface and device, refer more particularly to automobile gimbal splined shaft surface-coated nylon method and device.
At present, coating nylon on metal surface, especially automobile gimbal splined shaft surface-coated nylon all is to adopt the high pressure electrostatic painting process, this process is that nylon powder passes through high-pressure electrostatic spray gun generation magnetic, nylon powder is magnetized in the metal surface, dissolve in the metal surface through the nature of heating again, the metal surface nylon layer is uneven, can not guarantee the appearance and size and the precision of part.
The objective of the invention is to develop and a kind ofly can be coated in the metal surface, can guarantee the product design size again, and can reach the coating processes method and the device of certain precision.
Technical solution of the present invention is: the metal surface coating unit is the mould that can be heated simultaneously, be pressurizeed by a cover, this mould mainly contains upper die and lower die, clamp thimble, respectively have two semilune grooves in upper die and lower die two sides, when closing up in order to the discharging upper and lower mould, unnecessary nylon powder liquid in the mould.Earlier coated part is heated to 260 ℃ to 280 ℃, be incubated 20 minutes to 40 minutes, mould is installed on the injection machine, be heated to 180 ℃ to 200 ℃, again powdery nylon is added in the fluidized bed furnace, then heated components being applied the position inserts in the fluidized bed furnace, at this moment nylon powder overlays on the piece surface and dissolves and is thick liquid, the part that will be covered with nylon then takes out puts into immediately that heated mold location, clamping, upper and lower mould close up, pressurize 80 tons to 100 ton forces, keep-uped pressure 2 to 4 minutes, part is taken out in die sinking then.
The present invention compares with the spraying method of present employing, and is simple to operate, and the part behind the coating nylon can reach degree of precision, and with low cost, has favorable economic benefit and broad field of application and use value.
Fig. 1 is the automobile gimbal splined shaft part drawing of coating nylon.
Fig. 2 is the pressurizing mould figure that heats of coating nylon technology.
Adopt the present invention to apply automobile gimbal splined shaft 2, earlier splined shaft 2 is carried out sandblast and rinsing, then coated part is heated to 270 ℃, temperature retention time 30 minutes, with the mold heated to 190 ℃ that is installed on the injection machine, the powdery nylon 1010 is added in the fluidized bed furnace, heated components need apply the position and insert fluidized bed furnace again, nylon powder overlays on the splined shaft surface in the stove, and dissolve and be thick liquid, then mould patrix 3 is opened, splined shaft 2 is taken out in fluidized bed furnace, put into heated mold immediately, one end withstands with fixing thimble, and the other end rotates by hand and clamps thimble 1, makes the part location, clamp, to go up, counterdie closes up, 90 ton forces that pressurize, pressurize 3 minutes, part is taken out in die sinking then, remove the part overlap, can obtain qualified coated product.
