Description

Technical Field

[0002] In modern automobile structural systems, various types of support beams included have certain standard requirements in terms of their strength and impact resistance to meet the support for the rest of the vehicle structure. At the same time, in order to improve the strength-to-weight ratio of the vehicle and reduce the weight of the vehicle as much as possible while ensuring the strength of the vehicle, high requirements are placed on the beam forming process or method. At the same time, the process and method for manufacturing these beams preferably minimizes unwanted product dimensions and quality changes, and at the same time minimizes manufacturing costs, optimizes manufacturability, and minimizes waste. In the process of beam forming, how to minimize manufacturing costs with efficient processes, optimize products, make material utilization higher, and improve the applicability of beams has become the main starting point for current industry competition. For example, the floor space occupied by the forming device and the coordination between the forming devices have a direct impact on manufacturing costs and product quality.
