[0004] The current five-level maintenance process for the outer windshield frame uses the chemical reagent soaking method for the frame to remove paint. The existing four-level maintenance process for the outer windshield capsule uses the chemical reagent soaking method for the paint removal of the capsule. The soaking time of this paint removal method is long. Partial paint removal is poor, requiring secondary treatment; waste chemical reagent treatment process is complicated and costly; and it pollutes the surrounding environment heavily, which cannot meet environmental protection requirements

Abstract
The invention belongs to the technical field of maintenance processes and provides a maintenance process method for outer windshield assembly of high-speed rail motor train unit, which comprises assembly inspection, assembly depainting, assembly depainting post-treatment, assembly paint spraying treatment and finish paint treatment which are carried out in sequence. A key point for the metod is that when an assembly is an outer windshield frame, assembly depainting refers to frame sanding, that is, sanding treatment is carried out on the frame through a sanding machine; when the assembly is the outer windshield capsule, the assembly depainting refers to capsule polishing, that is, the pneumatic polishing disc is used for polishing the outer windshield capsule. According to the maintenanceprocess method, the labor efficiency is improved, the production cost is reduced, the pollution to the surrounding environment is reduced, and the environmental protection requirement can be met.
Description
technical field [0001] The invention belongs to the technical field of overhaul technology, and relates to an overhaul process method for an outer windshield assembly of a high-speed rail train set. Background technique [0002] The outer windshield frame of the high-speed rail EMU is made of welded aluminum alloy profiles, and the surface is sprayed with RAL3012 primer + RAL1002 primer + Chinese white topcoat. The material of the outer windshield capsule of the high-speed EMU is EPDM series rubber, which is processed and produced by hot molding and vulcanization; the surface of the outer windshield capsule is sprayed with "modified acrylic polyurethane primer + acrylic polyurethane topcoat". The outer windshield frame, the outer windshield capsule and the bead are connected by bolts to form the outer windshield of the vehicle body. It is located at both ends of the vehicle and is directly exposed to the atmospheric ozone layer. It has been exposed to wind, sunlight, and ult...
