Embodiment 1

[0050] It can be seen from the accompanying drawings that the present invention relates to an upper funnel ridge of a railway aluminum alloy wagon. The upper funnel ridge is integrally formed by splicing aluminum alloy profiles; Friction welding welds the aluminum alloy profiles to each other to form the upper funnel ridge of the whole aluminum alloy.

[0051] The aluminum alloy profiles include "A"-shaped aluminum alloy profiles 1 and composite structure aluminum alloy profiles 2, wherein, there is 1 "A"-shaped aluminum alloy profile and 2 composite structure aluminum alloy profiles, totaling 3 pieces; The composite structure aluminum alloy profile 2 includes a straight side 3, and there are two triangular reinforcing ribs on the inner surface of the straight side 3, one is a small triangular rib 4, and the other is a large triangular rib 5; the lower end of the straight side 3 The head is vertically connected with an inverted "F" shaped profile 6.

[0052] The aluminum allo...

Abstract

The invention relates to a railway aluminium alloy truck upper funnel ridge and friction stir welding production method. The whole upper funnel ridge is formed by splicing aluminium alloy sections; according to the shape of the upper funnel ridge on a truck body and requirements, different aluminium alloy sections are adopted, the aluminium alloy sections are mutually welded by friction stir welding, and the whole aluminium alloy truck upper funnel ridge is formed. The friction stir welding comprises the steps of arranging the aluminium alloy sections forming the railway aluminium alloy truck upper funnel ridge in sequence, and welding to connect all the aluminium alloy sections together by friction stir welding, thus forming the whole railway aluminium alloy truck upper funnel ridge. The railway aluminium alloy truck upper funnel ridge has the characteristics of stable structure, high strength and attractive appearance by adopting the aluminium alloy sections to form a wallboard, compared with an original method of riveting on a frame by using a board, the overall strength is enhanced greatly, and the appearance is very attractive.

Description

technical field [0001] The present invention relates to a method for manufacturing parts of railway wagons, in particular to a funnel ridge on a railway aluminum alloy wagon and a welding manufacturing method, in particular to a method for making the upper funnel ridge of a railway aluminum alloy wagon by friction stir welding, which belongs to Technical field of railway wagon manufacturing. Background technique: [0002] 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 one of ...
