　　3.1.2 The main production process and technology of the inspected party

　　(1) Overall production process

　　Figure 3.1.2.1 Overall production process

　　The company mainly produces the carriages and frames of fuel tricycles and electric tricycles, and the remaining parts are purchased. The carriage and frame structure are similar, and the production process is the same. Electric tricycles are relatively simple. According to the technical parameters provided by the manufacturer, the area of ​​the electric carriage is 60% of the area of ​​the fuel carriage, and the area of ​​the frame is 40% of the carriage.

According to the different production processes of the workshop, they can be divided into pickling process, car frame, carriage production process, surface treatment process, and final assembly process. The specific workshop production process is as follows:

　　(2) Carriage and frame workshop production process

　　Figure 3.1.2.2 Carriage and frame production process

　　The carriage and frame production processes are respectively completed in two special production workshops, which are divided into blanking processing area, welding area, and polishing area.

　　Cutting: Cutting and bending the frame and carriage pipe according to the production requirements, mainly responsible for the cutting, shearing, forming and other processing tasks of the structural parts in the product. The pipe material is mainly cut by grinding wheel and laser cutting machine; the profile is mainly cut by the cutting machine and the band saw; the forming of the components is completed on the punching machine; the bending parts are bent and formed on the CNC bending machine. The processed parts are assembled and welded in the welding zone, and the rusted and pre-processed parts are subjected to the pickling process.

　　Welding: Welding adopts carbon dioxide gas shielded welding process, and the main parts are welded by welding robot manipulator.

　　Polishing: The process mainly undertakes to remove the weld seam produced during the welding of the product, improve the flatness of the product, and prepare for the surface treatment.

　　(3) Production process of pickling workshop

　　Figure 3.1.2.3 Pickling production process

　　The pickling process is concentrated in a special pickling workshop, with a total of 2 production lines for processing parts with rust after cutting. At the same time, some parts that are difficult to be phosphated after assembly need to be phosphated in advance.

　　Degreasing: Utilize the saponification effect of the alkali component in the degreasing agent on the oil stain, and the emulsification effect of the surfactant composition on the oil stain to remove the greasy surface of the component.

　　Pickling: 10% dilute hydrochloric acid is used as the rust remover. After the pickling is completed, it enters the neutralization tank after two countercurrent washes.

　　Neutralization: Use 5% dilute sodium hydroxide as a neutralizer to adjust the PH value of the surface of the parts and reduce the subsequent impact. As the number of neutralization increases, the bath concentration and impurities are enriched, and need to be replaced regularly. Generally It is replaced once a month, and the replaced tank liquid enters the sewage station as waste water.

　　Phosphating: As part of the area of ​​some parts is covered after assembly, the exposed surface is reduced. At this time, the surface treatment is performed again, the effect is not good, and the phosphating treatment needs to be performed in advance.

　　(4) Production process of painting workshop

　　There are three closed coating lines. The surface treatment process is concentrated in the special coating treatment workshop, in which the frame production electrophoretic coating line replaces the original engineering powder coating line process, and the workshop production does not involve paint spraying.
