Description

Technical Field

[0001] The utility model relates to the technical field of forming dies, in particular to a forming die for an inner plate of an upper side beam of a new energy vehicle. Background Art

[0002] Generally, there are three types of pillars in the body of a car, from front to back, they are the front pillar A-pillar, the middle pillar B-pillar and the rear pillar C-pillar. For cars, these pillars not only play a supporting role, but also serve as door frames. Among them, the B-pillar is located between the front and rear seats of the cockpit. It extends from the roof to the bottom of the car and is the main part that supports the structural strength of the vehicle. The inner plate of the upper side beam of the car is connected to the upper end of the B-pillar. In order to improve the safety of the car, existing cars are equipped with side air curtains, which are set between the upper side beam of the car body and the ceiling pillars. In this way, when the vehicle is hit from the side, the side air curtain expands and can protect the occupants from the side. Therefore, its role is reflected in supporting the passenger compartment frame, protecting the safety of members, and providing strength support for the body anti-collision. Therefore, the rigidity and strength of the inner plate of the upper side beam play a very important role in the vehicle components. However, since the product is made of high-strength plate and the tensile strength of the plate reaches 811MPa, it is very difficult to stretch this plate and it is difficult to reach the yield strength of the plate. The requirements for the equipment are relatively high and the forming force during forming is huge. Theoretically, this forming force reaches 670 tons. The actual forming force required in production will be as high as 1,300 tons, so the tonnage requirement for the equipment will reach 1,600 tons. It is very easy to produce uneven internal stress distribution after forming, which will cause the product to rebound and twist after forming. Especially for the inner plate of the upper side beam of the automobile, the product itself is relatively small in height, relatively large in length and width, with fewer internal surfaces and shallow ribs on the surface. Therefore, its own rigidity is particularly poor and it is easy to twist. As shown in the attached figure Figure 1 The schematic diagram of the inner plate of the upper side beam of an automobile shown in the figure shows that the product is in the shape of a long and thin strip, on which there are many local concave and convex structures of different shapes and sizes, and there is an open platform in the middle of one of the long sides. The analysis results of the process scheme of directly stretching in combination with a forming mold in the prior art show that it has the following disadvantages:

[0003] 1. The product is severely twisted, with the twist value reaching as much as ±5mm. Specifically, the two ends of the product are warped up and the middle part tends to fall down, which cannot meet the size requirements;

[0004] 2. The principal strain on the product is uneven, and no effective extension is formed; the secondary strain is negative, and there is compressive strain; the reasons obtained through the analysis of the principal and secondary strains above show that the difference between the principal and secondary strains of the product is large after the stretching is completed, and the internal stress of the product is not released, resulting in such a huge distortion of the product;

[0005] 3. Most molding molds adopt a one-mold-one-out or one-mold-two-out structure. When one mold has one out, the production efficiency is too low; when one mold has two out, although the production efficiency will be improved, the mold volume will become huge. Utility Model Content
