The "dressing project" of Shengrun Automobile set the first automatic coating line of "spraying + powder spraying" process in the Liangshan special vehicle industry. Through the intelligent green transformation and upgrading, the production time of the painting workshop is reduced by 90%, the labor cost is reduced by 70%, and the other costs are reduced by 5%. The delivery period will be fully shortened by 6 days, which fully meets the environmental protection requirements and greatly improves the comprehensive benefits.
Painting is an important part of automobile manufacturing, among which the overall efficient automatic spraying and transfer of large special vehicle tank, while realizing no emission pollution, has always been a worldwide industry problem. In August, Shengrun Automobile successfully solved the problems in the world of special vehicle painting through "dressing Project". The overall dusting process adopted shot blasting + spraying "nano ceramic conversion film" treatment process, which made the coating adhesion stronger and not easy to fall off.
The art exhibition shows
Pre-processing equipment
Spray type multi-station pre-treatment unit, is to use mechanical scour to accelerate chemical reaction to complete the oil removal, water washing and other processes. The pretreatment process also uses the domestic famous brand automatic shot blasting machine, closed automatic working state, optimize the manual, environmental protection and high efficiency; The cleaning treatment of the workpiece after shot blasting adopts Z new environmental protection technology, no phosphating degreasing, silane film forming, increasing the adhesion of the powder and the weather resistance of the product (up to 5 times of the weather resistance).
Powder spraying system
Powder coating line according to the complexity of the workpiece, the optimization process combining science and technology with traditional technology is adopted to achieve high yield and high quality production mode. The use of international top powder coating, product color using European standard, no orange lines, high brightness, high leveling; The internal quality has reached the high-end position in the industry (weather resistance is up to 5-7 years), the glossiness has been increased by more than 5 times compared with the original painting process, and the external visual effect and touch sensation have reached the level of domestic main car and sedan. The powder coating thickness is uniform, one-time spraying can reach the standard thickness of 120μm, the original spray painting process needs three times to reach the standard film thickness, the efficiency is greatly improved.
Baking furnace
Oven is one of the important equipment in coating production line, and its temperature uniformity is an important index to ensure coating quality. Designed and constructed by the top construction team in China, the heating time is short, the insulation time is long, and the energy gap type work greatly reduces the energy consumption of the enterprise. The enterprise technology concept of high efficiency, energy saving and environmental protection has been realized. After testing, the temperature difference in the furnace is less than ±3oC, reaching the performance index of similar products in advanced countries.
Electric control system
The electric control of painting and painting line adopts centralized and single column control. According to the compiled control program, each process can be automatically controlled, data acquisition, monitoring and alarm, and the operation is intuitive and easy to maintain.
Hanging transport chain
The suspension conveyor is the conveying system of industrial assembly line and coating line. The continuous passing method can improve the production efficiency to a greater extent.
