Abstract
The invention discloses a special axle coating process for an automobile and relates to the technical field of production of automobile parts. The process comprises five technological processes: assembly degreasing treatment, assembly cleaning and rust-preventing treatment, assembly water-blowing and drying treatment, assembly paint spraying treatment, and assembly drying and forced cooling treatment. The process disclosed by the invention adopts a novel material, a novel process and a brand new coating flow, and a forced cooling process and a drying process before primer spraying in a conventional process are cancelled while the time of the last forced cooling process is prolonged. As two relatively miscellaneous processes are cancelled, in the coating process, the production time is relatively shortened and the production cost is lowered while the product quality is improved.

(2) assembly cleans and antirust treatment: first pass through hot water clean Special-truck-axle assembly comprehensively, then
By the antirust solutions of more than 40 DEG C, Special-truck-axle carried out antirust spray 150s-200s；
(3) assembly blows water and drying and processing: first passes through compressed air and blows Special-truck-axle assembly hydrops portion
Water processes, then is dried it by the hot-air that temperature is 90 DEG C-100 DEG C；
(4) assembly sprays paint process: process of spraying paint include the primer spray to Special-truck-axle assembly process, topcoating
Process and levelling processes；
(5) assembly is dried and strong cold treatment: again Special-truck-axle assembly is carried out hot air dries, then by it
It is positioned over strong cold house to carry out forcing cooling to process below-40 DEG C of temperature.
Preferably, in step (2), the expulsion pressure of the hot water in cleaning treatment is 0.5MPa-0.9MPa, temperature
Degree is 60 DEG C-70 DEG C, and injecting time is 150s-200s.
Preferably, in described step (2), the expulsion pressure of the antirust solution in antirust treatment is 0.4MPa-0.8MPa,
Temperature is 40 DEG C-50 DEG C, and injecting time is 150s-200s.
Preferably, a length of 25min-35min during drying and processing in described step (3).
Preferably, the temperature of the strong cold treatment Zhong Qiang cold house of described step (5) is-40 DEG C～-60 DEG C, processes
Time is 220s-280s.
Use technical scheme, have employed new material and new technology and brand-new coating process, cancel
In traditional handicraft strong cold technique before primer spray with together with drying procedure, and increase last strong cold journey together
The time of sequence, the program the most numerous and diverse owing to eliminating twice, this coating process is improving while product quality,
Relatively reduce the production time, reduce production cost, solve production efficiency in traditional handicraft low, and car
The bridge paint film resistance to mist time is short, the problem that vehicle bridge is of low quality.
Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of automobile special vehicle bridge coating process of the present invention.
