Threshold boundary beam backup pad manufacturing mould

Technical Field

The utility model belongs to the technical field of automobile body structural design's technique and specifically relates to a threshold boundary beam backup pad manufacturing mould is related to.

Background

The rigidity of the car body is the foundation of the car body, the phenomena of shaking, rolling and abnormal sound in the whole car are easily caused by insufficient rigidity, and meanwhile, the problems of durability, stable operation and the like are caused. Factors that affect the stiffness of the vehicle body are the layout of the vehicle body frame, the beam section characteristics, and the joint stiffness. The body beam and the solid body need to form a complete closed structure, and the good rigidity of the whole structure can be ensured. If no closure is formed between the beam and the pillar, the overall body stiffness is greatly reduced. At present, bending load borne by a vehicle body seat position can be transmitted to a threshold side beam through a seat cross beam and then transmitted to a vehicle body frame structure.

The prior commonly used doorsill edge beam supporting plate structure is shown in figure 1, and comprises a central plate 1, wherein the cross section of the central plate 1 is rectangular, a rectangular main groove 11 is pressed on the upper surface of the central plate 1, two main convex hulls 12 are formed in the main groove 11 in a protruding manner, and a main through groove 13 is formed in the centers of the main convex hulls 12. The side edges of the central plate 1 are divided into a main long edge 14, a first main short edge 15 and a second main short edge 16, the main long edge 14 is fixedly connected with a side plate 2, and the side plate 2 is perpendicular to the central plate 1 and is positioned on the same side of the central plate 1. The side plates 2 are also rectangular, the sides of which are divided into a long side 21 and a short side 22, the long side 21 and the long side 14 are equal in length, one long side 21 of the side plates 2 is connected with the long side 14 connected with the central plate 1, and the sides are vertically positioned on the same side of the central plate 1. A first flanging 151 is integrally formed on the first main short edge 15 of the central plate 1, one end, far away from the central plate 1, of the first flanging 151 is located on one side, far away from the side plate 2, of the central plate 1, and the first flanging 151 is connected with the side plate 2; a second flanging 161 is integrally formed on a second main short edge 16 of the central plate 1, the second flanging 161 and the central plate 1 are located in the same plane, a short flanging 221 is fixedly connected to a side short edge 22 of the side plate 2, a long flanging 211 is fixedly connected to one side long edge 21 of the side plate 2 which is not connected with the central plate 1, and the short flanging 221 and the long flanging 211 are both located on one side, far away from the other side plate 2, of the side plate 2 connected with the short flanging 221.

At present, a mould is usually adopted for processing to directly press a plate to form the threshold boundary beam supporting plate, but when the mould is used for processing the threshold boundary beam supporting plate, the position where a first flanging is connected with a side edge needs to be bent while being obliquely stretched, so that a side plate is formed, the plate at the position is easy to break due to overlarge stress, and a produced rough supporting plate is a defective product, so that the production cost is increased.
