Embodiment Construction

[0022] The main process of the painting process of the axle of the present invention is: degreasing → hot water washing → anti-rust water washing → water blowing shielding → drying → strong cooling → spraying primer → spraying top paint → leveling → drying → strong cooling. The vehicle axle coating line of the present invention adopts new materials, new technology and advanced 2C1B coating system. cost of running the production line.

[0023] The 2C1B coating system adopted by the axle coating line of the present invention: two coatings and one baking; that is, after the primer is sprayed on the workpiece, it will be leveled and flashed for a short time, and then the topcoat will be wet-on-wet sprayed directly, and the two-layer paint film will be dried. room for one-time drying. After adopting the 2C1B coating system, the primer drying process was canceled, and a corresponding primer drying room was omitted, thereby reducing the investment in fixed assets by about 500,000 yu...

Abstract

The invention discloses a process for coating an automobile axle. Main coating flow of the automobile axle comprises the following steps of: degreasing, hot water rinsing, antirust water rinsing, water blowing shielding, drying, forced cooling, primer spraying, finish paint spraying, leveling, drying and forced cooling. Compared with the conventional process in China, a primer drying process and a corresponding primer drying chamber are eliminated. Due to the adoption of a new material, a new process and an advanced 2C1B coating system, the process has the advantages of improving the quality of a product coating, eliminating a process, reducing the investment in fixed assets and saving the production and operating costs of a production line compared with the same industry.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle manufacturing, and in particular relates to an automobile axle coating process. Background technique [0002] The automobile axle coating process is an important step in the manufacture of automobile axles. It is an important guarantee for the automobile axle to resist acid, alkali and organic solvent corrosion. It is also the bottleneck of automobile axle production at present. [0003] At present, in the field of automobile axle coating technology, the existing technology mostly adopts the traditional coating process. The main process of the traditional coating process is: degreasing→hot water washing→cold water washing→water blowing shielding→drying→forced cooling → spray primer → primer drying → spray topcoat → topcoat drying → leveling → drying → forced cooling. [0004] In this traditional process, after the primer is sprayed on the axle assembly, it needs to enter the primer drying r...
