Abstract

The invention provides an aluminum apron board for a railway vehicle and a machining method of the aluminum apron board. The aluminum apron board for the railway vehicle comprises an aluminum plate and an aluminum sectional material frame. The aluminum plate and the aluminum sectional material frame are connected in a spot welding mode. The aluminum apron board further comprises a filter. A vent is formed in the aluminum plate. The periphery of the vent is fixedly provided with riveting studs. The filter is fixed to the riveting studs and shields the vent. The outer surface of the aluminum plate is coated with a paint layer. As the vent is formed in the aluminum plate and the riveting studs are arranged on the periphery of the vent, the filter is installed on the aluminum plate through the riveting studs. Firstly, the riveting studs are directly riveted on the aluminum plate so as to reduce deformation of the aluminum plate and the flatness requirement of the aluminum apron board is met. The outside air can enter the inner side of the aluminum plate through the vent and the filter and the ventilation performance of the aluminum apron board is greatly improved. Under the condition that the appearance flatness is ensured, the ventilation performance of the aluminum apron board for the railway vehicle and the air cleanliness are improved.

Description

Technical field [0001] The invention relates to railway vehicles, in particular to an aluminum skirt board for railway vehicles and a processing method thereof. Background technique [0002] At present, the two sides of the railway car body are usually provided with skirt boards to protect the equipment under the car body. Among them, the skirt board is usually made of stainless steel, and the skirt board usually includes a stainless steel plate and a stainless steel frame, which are welded together. Due to the use of stainless steel, the weight of the skirt board is heavier, resulting in a heavier overall weight of the railway vehicle. Chinese Patent No. 2009203125130 discloses a structure of the skirt board of the equipment compartment of the vehicle body underframe, which is made of aluminum plate and aluminum profile frame to reduce the overall weight of the skirt board. However, the skirt plate structure requires a high level of flatness to ensure accurate installation on ...
