Technical Field

[0001] This utility model belongs to the field of bumper processing technology, and in particular relates to a punching device for bumper processing. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. Many years ago, car bumpers were made by stamping steel plates into channel steel, which was then riveted or welded to the longitudinal beams of the vehicle frame, leaving a significant gap between the bumper and the body, resulting in an unsightly appearance. With the development of the automotive industry and the widespread use of engineering plastics, car bumpers, as an important safety device, have undergone significant innovation. The manufacturing process of car bumpers requires the use of punching equipment to create holes in the bumper.
