Embodiment 1

[0047] by attaching figure 1 and 2 It can be seen that the present invention relates to a side wall panel of a railway aluminum alloy funnel car. The side wall panel is formed by splicing aluminum alloy profiles as a whole; The aluminum alloy profiles are welded to each other to form a whole aluminum alloy side wall panel.

[0048] Further, the aluminum alloy profiles include 3 types of profiles, among which, there are 16 inline profiles, 4 profiles with "herringbone" shaped ribs in the middle of a character, 5 profiles with triangular ribs in the middle of a character, and There are 4 profiles with bosses in the middle, a total of 29 pieces. Arrange the above profiles in order and weld them together by friction stir welding to form a whole piece of aluminum alloy side wall panel to form a whole piece of aluminum alloy side wall panel to form a whole piece of aluminum alloy side wall panel wall panels.

[0049] Further, the aluminum alloy profiles are arranged in a symmetr...

Abstract

Provided is a sidewall plate of a railway hopper wagon made by aluminum alloy and a friction-stir welding method thereof. The sidewall plate is integrally formed by splicing of aluminum alloy sections. According to the shape and the requirement for the sidewall plate of a wagon body, different aluminum alloy sections are adopted and welded together by friction-stir welding in order to form the overall sidewall plate made by aluminum alloy.The friction-stir welding is realized by arraying the aluminum alloy sections forming the sidewall plate of the railway hopper wagon according to the sequence. All the aluminum alloy sections are welded for connection by means of friction stir welding. Therefore, the overall sidewall plate of the railway hopper wagon is formed.The aluminum alloy sections are adopted for forming the wall plate featuring a stable structure, high strength and attractive external appearance. Compared with the mode that plates are utilized for being riveted onto a framework, the overall strength is improved a lot; and the appearance looks attractive.

Description

technical field [0001] The invention relates to a component of a railway freight car vehicle and a manufacturing method thereof, in particular to a side wall panel of a railway freight car and its welding method, in particular to a method and product for making a side wall panel of a railway freight car by friction stir welding, belonging to Technical field of railway wagon manufacturing. [0002] Background technique: [0003] Railway cargo transportation is an important part of railway transportation, and the vehicles used to carry goods on the railway are collectively called railway wagons. According to their different purposes, they can be divided into general-purpose trucks and special-purpose trucks. The main types are box car, gondola car, tank car, flat car and hopper car etc. Recently, in order to improve the transportation capacity, it has been proposed to use aluminum alloy materials to make railway wagons, among which the aluminum alloy railway hopper car is on...
