Problems solved by technology

[0010] 1. The metal door frame of the car is usually made of metal, which is easy to rust, and the processing process often adopts an assembly line operation, and there is a period of time between the later painting, so it is easy to appear that the metal door frame of the car has been rusted before the post-processing process such as painting, resulting in the need for reprocessing Rust removal affects product quality and reduces process

Abstract

The invention discloses a machining process of metal automobile door frames. The machining process comprises the following steps A, welding is conducted; B, rough polishing is conducted; C, finish polishing is conducted; D, the metal automobile door frames are sequentially placed on hangers after being subjected to finish polishing and are then conveyed cyclically; and E, in the operating direction, a water-based antirust agent solution is sprayed to the metal automobile door frames on the hangers first to form antirust protective films, then the appearances of the metal automobile door framescovered with the antirust protective films are inspected manually or through equipment, and finally, the metal automobile door frames are taken from the hangers fixed to a conveyor so as to be subjected to dimension inspection. The metal automobile door frames obtained through the machining process have a good antirust effect and facilitate subsequent machining, and the quality and quality stability of final products are guaranteed; and in addition, the machining efficiency is high, the quality is good, the dimensional precision of the metal automobile door frames can be guaranteed, and the surface smoothness is good.
