Problems solved by technology

[0003] For some specific automobile structures, such as battery boxes, there are also high requirements for vehicle vibration and protection. Some existing support and reinforcement beams are hollow structures that are welded and spliced ​​by multiple molded shells. Due to splicing Moreover, there are many welding points, resulting in poor structural continuity and integrity. It can only provide simple support and protection, and its strength has certain limitations. Regular inspection of the welds will further increase the cost of the vehicle, and will also have a negative impact on the overall structure of the vehicle in the later period. Therefore, in order to ensure the strength and impact resistance of the battery box, it can be manufactured by referring to the beam forming process. To achieve high strength and impact resistance properties similar to beams, but the corresponding applications or forming methods are still few or not very clear

Embodiment 1

[0040] Such as Figure 1-8 As shown, a support and reinforcement beam is processed and formed by the following forming method:

[0041] Such as Figure 5 As shown, the metal sheet coil is first uncoiled by the uncoiler 6 to form a continuous metal sheet, and then the metal sheet is leveled by the punching and leveling machine 7, and at the same time, positioning holes are processed at the position to be cut for The location of the subsequent cutting is positioned, and then according to the cross-sectional shape requirements of the beam, the flattened metal sheet is sent to the forming rolling line 8 and rolled into a continuous hollow beam structure. After forming, the hollow beam structure is formed by 11 pairs of shaping rollers. The outer contour of the frame is shaped, and then the formed plate is cut into individual hollow beams according to the positioning holes by the cutting machine 12. The hollow beam structure is used as a supporting and reinforcing beam for use. O...

Embodiment 2

[0047] On the basis of the process flow described in Embodiment 1, when forming the first protrusion 1, as Figure 6 As shown, the first raised rolling section 81 can be divided into a forming section 811 and a bending section 812, and the bending section 812 rolls the first flat section near its edge into a horizontal side 4 and a straight side respectively. 3, such as figure 2 As shown, the straight side 3 is perpendicular to the undeformed part of the first flat section to form the wide side of the reinforced beam, and the horizontal side 4 is perpendicular to the straight side 3, and then the forming section 811 rolls out a U-shaped concave part on the horizontal side 4 121, and let the transverse side 4 at the U-shaped recess 121 be parallel to the undeformed part of the first flat section and fit together and welded.

[0048] When forming the second protrusion 2, the second flat section of the sheet metal is gradually bent by the second protrusion rolling section 82 to...

Embodiment 3

[0050] On the basis of the process flow described in Embodiment 1 or Embodiment 2, the first protrusion 1 can be formed by the first protrusion rolling section 81 first, and then the second protrusion roller can be formed after the first protrusion 1 is welded and finalized. The pressing section 82 shapes the second protrusion 2 .

Abstract

The invention relates to a supporting and reinforcing beam which comprises an integrated hollow beam formed through rolling, the hollow beam comprises a linear section, the two ends of the linear section are formed into a first protrusion and a second protrusion through rolling respectively, and the first protrusion and the second protrusion are opposite in orientation. The hollow beam is integrally formed and internally provided with two supporting walls , the structural stability is guaranteed while the weight of the beam is reduced, the high strength and impact resistance of the beam are met, thus, the manufactured supporting and reinforcing beam can be directly applied to manufacturing of an automobile battery box on the basis of the characteristic that the beam is used for supportingand reinforcing, therefore, the requirements of the automobile battery box for automobile vibration and protection are met, and the supporting and reinforcing beam can adapt to severe working environments.

Description

technical field [0001] The invention relates to the technical field of beam processing and forming, in particular to a supporting and strengthening beam and a forming method thereof. Background technique [0002] In the modern automobile structure system, the various support beams included have certain standard requirements in terms of their strength and impact resistance characteristics, so as to meet the support for the rest of the vehicle structure, and at the same time, in order to improve the strength-to-weight ratio of the vehicle, the strength of the vehicle has certain To reduce the weight of the car as much as possible under the premise of guarantee has high requirements on the forming process or method of the beam. At the same time, the process and method of manufacturing the beams preferably minimizes unwanted product dimensional and mass variations while minimizing manufacturing costs, optimizing manufacturability and minimizing scrap. In the beam forming proces...
