Aluminum apron board for railway vehicle and machining method thereof

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 a railway vehicle, in particular to an aluminum skirt plate for a railway vehicle and a processing method thereof. Background technique [0002] At present, skirts are usually arranged on both sides of the car body of the railway vehicle to protect the equipment at the lower part of the car body. Among them, the apron is usually made of stainless steel, and the apron 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 plate is heavy, resulting in a heavy overall weight of the rail vehicle. Chinese Patent No. 2009203125130 discloses a car body underframe equipment cabin skirt structure, which is made of aluminum plates and aluminum profile frames to reduce the overall weight of the skirt. However, the skirt plate structure requires high flatness to ensure accurate installation on the railway vehicle, thus, the aluminum plat...
