Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a bending device for strip-shaped metal products. Background Technology

[0002] In modern industrial manufacturing, strip metal products are widely used in many industries such as construction, automobile manufacturing, and electronic equipment. In automobile manufacturing, various metal brackets and frames are often made from strip metal through bending. Similarly, some metal connectors inside electronic equipment rely on bending processes to meet specific assembly requirements.

[0003] The prior art discloses a bending device for strip-shaped metal products, with publication number CN219616444U, relating to the field of bending devices. This bending device includes a support base, a mounting bracket, and a fixing base. Two bases are disposed on the lower surface of the support base, the mounting bracket is disposed on the upper surface of the support base, and the fixing base is mounted on the upper surface of the support base. In this bending device, the strip-shaped metal product is inserted between two extrusion bases. Under the action of a centering component, the two extrusion bases extrude and fix the strip-shaped metal product. When the bending head contacts the strip-shaped metal product, it bends the product, reducing the distance between its two ends. The centering component ensures that the strip-shaped metal product is centered, thus preventing skewing during bending.

[0004] The aforementioned strip metal product bending device inserts the strip metal product between two extrusion seats. Under the action of the central component, the two extrusion seats extrude and fix the strip metal product. However, the aforementioned strip metal product bending device does not have a single softening component that can be precisely controlled during bending, so it cannot soften accurately and bend quickly. The effect during use is not good and needs to be improved. Utility Model Content
