Aluminum-piece nylon coating machine and coating method

Abstract

The invention discloses an aluminum-piece nylon coating machine and coating method. Undercoat painting mechanisms are arranged on the two sides of a feeding conveying machine, a truss and a mechanicalarm are arranged at the tail end of the feeding conveying machine, and a medium-frequency heating furnace and a nylon powder box are arranged below the truss; a numerical-control and electronic-control operating table and a water cooling tower are arranged outside the truss, wherein the numerical-control and electronic-control operating table provides an electric wire to be connected to the feeding conveying machine, the undercoat painting mechanisms, the nylon powder box, the truss and the mechanical arm; the medium-frequency heating furnace is connected with a medium-frequency heating cabinet, and cooling is carried out through the water cooling tower. For achieving the aims that the strength loss of an aluminum piece is lowest, and melting of nylon powder is considered, the temperatureof the aluminum piece is controlled to be 250 DEG C to 255 DEG C in the medium-frequency heating furnace, two times of powder dipping are carried out, the aluminum piece enters the nylon powder box for the first time and is soaked into the nylon powder, and then time stays for 2 seconds to 3 seconds; powder dipping is carried out for the second time after the aluminum piece is separated from thenylon powder box and stays for 1.5 seconds, the aluminum piece enters the nylon powder box for the second time and is soaked into the nylon powder to also stay 2 seconds to 3 seconds, and it can be achieved that the coating thickness is controlled to be 0.5 mm to 0.6 mm.
