Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in detail below.

[0027] The reference signs in the accompanying drawings of the specification include:

[0028] Air duct support 1, bent plate 2, automobile beam 3, fillet weld 4, butt weld 5.

[0029] A lightweight aluminum alloy automobile roof welding process, comprising the following steps:

[0030] A. Preparation before welding: pass the car roof air duct bracket through such as Figure 1~2 The extrusion die shown is integrally extruded, and the air duct support is cut equidistantly after the integral extrusion. The cross-section of the extrusion die is the same as the end surface structure formed by two L-shaped angle aluminum tailor-welded on the upper and lower sides of the longitudinal beam. ;

[0031] B. Formal assembly: clamp the air duct support 1, automobile beam 3 and bending plate 2 after equidistant cutting on the welding tool (such as Figure 3-6 As shown), the reverse deformation is...

Abstract

The invention belongs to the technical field of lightweight of automobiles, and relates to a welding process for a lightweight aluminum alloy automotive roof. The welding process of the lightweight aluminum alloy automotive roof comprises the steps that an air duct support of the automotive roof is integrally formed through extrusion by an extrusion die, and the air duct support integrally formedthrough extrusion is cut at equal intervals; a corner weld structure is formed between an automotive crossbeam and a bent plate; after the two sides of a weld are polished, the automotive crossbeam and the bent plate are welded, wherein the welding current is 155-165 A, the voltage is 21.2-22.5 V, and the welding speed is 9-11 mm / s; and a butt weld structure is formed between the air duct supportand the automotive crossbeam, the bevel angle is 55 degrees, and after the two sides of a weld are polished, the air duct support and the automotive crossbeam are welded, wherein the welding current is 155-165 A, the voltage is 21.2-22.5 V, and the welding speed is 12-14 mm. By adoption of the welding process of the lightweight aluminum alloy automotive roof, the problems that in the machining process of the automotive roof, the welding workload is large, and operation is complex are solved.

Description

technical field [0001] The invention belongs to the technical field of lightweight automobiles, and relates to a lightweight aluminum alloy automobile ceiling welding process. Background technique [0002] The car roof is an important part of the car, and its production quality plays an important role in the overall quality of the car. In actual production and manufacturing, the longitudinal beam of the existing structure is often welded with two L-shaped angle aluminum to ensure the performance of the air duct bracket. Due to the large amount of welding and complicated operation during production, the aluminum alloy car roof The large amount of welding cannot guarantee the overall size of the car roof, and seriously affects the processing efficiency of the aluminum alloy car roof. Contents of the invention [0003] In view of this, the present invention provides a light-weight aluminum alloy automobile roof welding process in order to solve the problems of large amount o...
