Abstract
The utility model aims at providing a can alleviate door closure shell plate deformation's door plant single face spot welding structure, including setting up at the peripheral flanging of door closure shell plate and setting up at the peripheral inside flange of door closure inner panel, the inside flange closes on the face of flanging one side and goes up to the protruding the stretching of outside flange and be provided with the convex closure, and the projection on the turn-ups covers the convex closure including the flanging. In the scheme, the convex hull of the turned-over edge is contacted with the turned-over edge surface, and due to the existence of the convex hull, a certain gap exists between the turned-over edge convex hull and the bottom surface turned-over edge, and the gap can effectively reduce the acting force of the single-side spot welding clamping mechanism on the bottom surface turned-over edge in the clamping and welding process, so that the deformation of the turned-over edge is reduced.
Description
Technical Field
The utility model relates to an automobile welding production technical field, concretely relates to door plant cover single face solder joint structure.
Background
In the production process of a body-in-white, a single-side spot welding process is generally adopted to weld the inner plate and the outer plate of the door cover together after edge covering, so that the problem of inner plate and outer plate movement in the process of welding, loading and transporting to coating is solved, and the qualification rate of the matching gap of the body is improved; the single-side spot welding is to apply pressure on the outer surface of the door cover for welding, welding parameters are difficult to control, especially the welding pressure parameters are too large under the condition that other parameters are not changed, and an outer surface part is easy to deform; and the welding pressure is too low, so that the breakdown or insufficient welding defects are easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can alleviate door closure planking deformation's door plant single face solder joint structure.
In order to realize the purpose, the utility model discloses a technical scheme be: a single-side spot welding structure for a door cover plate comprises an outward flange arranged on the periphery of a door cover plate and an inward flange arranged on the periphery of a door cover plate inner plate, wherein the inward flange is provided with a convex bag in a protruding mode towards the outward flange on the surface close to one side of the outward flange, and the convex bag is covered by the projection of the outward flange on the inward flange.
In the scheme, the convex hull of the turned-over edge is contacted with the turned-over edge surface, and due to the existence of the convex hull, a certain gap exists between the turned-over edge convex hull and the bottom surface turned-over edge, and the gap can effectively reduce the acting force of the single-side spot welding clamping mechanism on the bottom surface turned-over edge in the clamping and welding process, so that the deformation of the turned-over edge is reduced.

FIG. 2 is a plan view of the inner flange;
FIG. 3 is a plan view after hemming; (dotted line is outward turned over edge, solid line is inward turned over edge)
Fig. 4 is a cross-sectional view of fig. 3.
Detailed Description
With reference to fig. 1-4, a single-side spot welding structure for a door cover plate includes an outward flange 10 disposed on the periphery of an outer plate of the door cover plate and an inward flange 20 disposed on the periphery of an inner plate of the door cover plate, where the inward and outward flanges 10, 20 are only suitable for distinguishing which plate is the outward flange, and it is not intended that the turning direction of the outward flange is inward or outward, it can be known from the drawings that the turning directions of the outward flange 10 and the inward flange 20 are the same, a convex bag 21 is protruded toward the outward flange 10 on the plate surface of the inward flange 20 near the side of the outward flange 10, and the projection of the outward flange 10 on the inward flange 20 covers the convex bag 21. The convex hull 21 of the turned-over edge 20 is contacted with the turned-over edge surface, and due to the existence of the convex hull 21, a certain gap exists between the turned-over edge 20 and the bottom surface turned-over edge 10, and the gap can effectively reduce the acting force of the single-side spot welding clamping mechanism on the bottom surface turned-over edge 10 in the clamping and welding process, thereby reducing the deformation of the turned-over edge 10.
Preferably, generally speaking, the projection of the outer edge a of the outer flange 10 on the inner flange 20 is located at the middle position of the inner flange 20, that is, the outer flange 10 cannot completely cover the convex hull 21, so that the outer edge a and the convex hull 21 correspond to each other, the extension 11 extends outwards, the projection of the extension 11 on the inner flange 20 covers the convex hull 21, and the convex hull 21 is completely covered by adding the extension 11.
Specifically, the extending portion 11 is overall in an isosceles trapezoid shape, the outer edge of the convex hull 21 is located outside the projection of the outer end edge a on the inner flange 20, and the projection of the end edge b of the extending portion 11 on the inner flange 20 is outside the outer edge of the convex hull 21.
Further, the inner end edge c of the outer flange 10 is projected on the surface of the inner flange 20 to the outside of the inner flange 20. The convex hull 21 is integrally stamped with the inner flange 20.
