Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a continuous mold for segmented forming of an outer motor bracket. Background Technology

[0002] The outer motor bracket is an automotive component with a Z-shaped structure and usually has several reinforcing ribs to ensure structural strength.

[0003] In existing technologies, the fabrication of the outer motor bracket typically includes processes such as edge trimming, reinforcing rib forming, bending, shaping, edge trimming again, flanging, punching, and cutting. Since the reinforcing ribs cover the bending area, this increases the difficulty of forming. During the bending process, material flow can be obstructed, and this poor flow can easily scratch the coating on the galvanized sheet, causing scratches or indentations on the product, affecting its appearance, quality, and durability.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content
