Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] Embodiments of the invention include:

[0019] An infrared closed welding method for an instrument panel air duct, comprising the following steps:

[0020] Step 1, establishing welding ribs: building welding ribs with a sealed surrounding structure that can be welded and matched with each other on the splicing surfaces of the front defrosting cover plate workpiece, the instrument panel workpiece, and the air duct cavity plate workpiece;

[0021] Step 2, matching the heating pipe network: constructing the end-...

Abstract

The invention discloses an infrared closed welding method for an instrument panel air duct. The method comprises the following steps: 1, establishing of a welding rib; 2, matching of a heating pipe network; 3, manual pre-positioning; 4, welding preparation; 5, preheating before welding; 6, quality inspection before welding; 7, welding and pressing; and 8, radiating and cooling, thereby completing welding. In this way, the infrared closed welding method for the instrument panel air duct has the advantages that the air duct is formed by welding an instrument desk and replaces a traditional ventilation duct, the problem of neglected loading and solder skips of manual operation is effectively solved, the screw assembly process is omitted, the light-weight integrated production form of an automobile is achieved, the production efficiency is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of instrument panel welding, in particular to an infrared closed welding method for an instrument panel air duct. Background technique [0002] With the development of my country's automobile industry, the requirements for the lightweight of automobiles are also increasing. In the existing technology, the assembly process of the air duct of the automobile dashboard is relatively complicated, and there are many manual operation interface processes. It needs to weld the bracket and then connect it with screws. The production of fixed air ducts is time-consuming and laborious, and the work efficiency is low. At the same time, the quality of the whole vehicle is increased. The cooperation between the various processes is not compact enough, and problems such as missing installation are likely to occur. After a long time, screws are prone to loosening. The environment of process equipment configuration It is impossible to me...
