Background technology
Extending beam is a vitals of automobile, these parts play very large effect in vehicle body, and the structure of current extending beam, as shown in Figure 1, the extending beam blanked part of current use easily ftractures at fillet place, in Y-direction without guiding, when welding with floor, and easily cause the edge joint weld of solder joint between extending beam and base plate, thus cause the solder joint between extending beam and floor to there is the risk of Cracking Failure, in Z-direction without guiding, when welding with threshold internal plate, extremely easily cause solder joint edge joint weld between extending beam and threshold internal plate, thus cause the solder joint between extending beam and threshold internal plate to there is the risk of Cracking Failure.
Utility model content
The utility model provides a kind of welding to lead and prevents the extending beam of edge bead, is intended to solve blanked part cracking, and Y-direction easily causes the problem of edge bead without guiding without guiding, Z-direction.
The utility model realizes like this, a kind of welding leads and prevents the extending beam of edge bead, this extending beam comprises base plate, the first side plate and the second side plate, the relative both sides of described base plate are located at respectively by described first side plate and the second side plate, microscler depressed part is provided with in the middle of the inner face of described first side plate and the second side plate, the cross-sectional plane of described depressed part is circular arc, and described depressed part is parallel with described base plate, and the angle of described first side plate and the non-connecting bottom board of the second side plate is rectangular.
Further technical scheme of the present utility model is: described first side plate and the second side plate are provided with and are provided with flange laterally.
Further technical scheme of the present utility model is: the vertical flange in position, angle and the horizontal flange contact position of described first side plate and the second side plate are provided with opening.
Further technical scheme of the present utility model is: described base plate is provided with two parallel raised lines.
Further technical scheme of the present utility model is: be provided with knock hole between two described raised lines.
Further technical scheme of the present utility model is: the two ends of described base plate are respectively equipped with downward swash plate.
The beneficial effects of the utility model are: cancel and floor, the knuckle of two orthogonal welding edges that threshold internal plate coordinates, efficiently solve the problem of blanked part cracking risk, extending beam mates the part of Y-direction step on face with threshold internal plate, there is provided the location of Y-direction can to welding gun electrode head, electrode tip is fully constrained in effectively in welding region, ensure that the solder joint between extending beam and front floor there will not be edge bead, thus effectively ensure that the strength and stiffness of body in white lower body reach design value, extending beam mates one end flange in face Y-direction with floor is widened, then add the efficient weld area between extending beam and floor, ensure that electrode tip is fully constrained in effectively in welding region, extending beam mates the part of Y-direction step on face with threshold internal plate, there is provided the location of Z-direction can to welding gun electrode head, below Z-direction electrode tip being fully constrained in step part, ensure that the solder joint between extending beam and threshold internal plate there will not be edge bead, meanwhile, also ensure that the safety distance of welding gun and threshold internal plate, can not cause in welding process and must shunt, thus effectively ensure that the strength and stiffness of body in white lower body reach design value.
