Embodiment Construction

[0020] The following is based on Figure 1 to Figure 5 , the embodiments of the present invention are given, so that the functions and features of the present invention can be better understood.

[0021] combine figure 1 with image 3 As shown, the hot air bending riveting welding machine for automobile exterior plastic parts of the present invention includes three components: a prolate welding rod 1 , a diamond-shaped welding head 2 and a blower 3 .

[0022] On non-slender parts, if the edge part needs to be connected to another part, an elongated welding rod 1 can be designed for connection, and the cross section of the elongated welding rod 1 can be in any shape.

[0023] The diamond-shaped welding head 2 is used to press down the welding rod 1 from an oblique direction F to bend the welding rod 1 to one side.

[0024] The blower 3 is used to heat the part of the welding rod 1 that needs to be bent, so that the part reaches the softening temperature of the plastic.

Abstract

The invention relates to a special welding method and a welding machine design used between automotive exterior trimming plastic parts. A welding object of the welding machine is the same as an ordinary rivet welding part, but can be bent to fasten a workpiece instead of generating a mushroom head. The welding machine adopts hot air welding machine principle to only bake the local part of a single-edge welding bar to a softening temperature by concentrating hot air, adopts a special welding head, and simultaneously pushes the welding head to bend to the side required by a scheduled design in the pressing process. The bent welding bar can be welded and fused to another workpiece or only be bent and pressed to another workpiece tightly according to different requirements. The welding methodcan be adopted to provide appearance requirements of the parts in the special field that the generation of the mushroom heads causing the visible welding marks is avoided.

Description

technical field [0001] The invention relates to the field of plastic welding, in particular to a hot air bending riveting welding machine and a welding method for automobile exterior plastic parts. Background technique [0002] At present, there are more and more functions of automobiles, and the modular supply method makes more and more parts integrated on the front and rear bumper exterior assemblies. Because welding can improve work efficiency, provide more stable and reliable fastening effect and rich design freedom. Therefore, in addition to the traditional clamping, screw, adhesive tape and other fastening assembly methods, welding is more and more used in the bonding of exterior trim assemblies. For the special appearance requirements of exterior parts, if the welding spot is at the edge of the welded part or the visible part of the bevel appearance, the welding method is at high risk and an unacceptable bonding method. In order to expand the application field and i...
