Description

Technical Field

[0001] The utility model relates to the technical field of bending, in particular to a novel bending jig. Background Art

[0002] Stamping dies are specialized equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping is a pressure-forming process at room temperature that uses a die mounted on a press to apply pressure to the material, causing it to separate or plastically deform, thereby producing the desired part. This process is typically used on assembly lines, also known as assembly lines.

[0003] The bending jig machine is a type of stamping die. It uses a cylinder to drive the bending pressure head to stamp the workpiece, causing it to deform and complete the bending. When existing bending machines bend wire-shaped workpieces, they can generally only use several bending stamping cylinders to stamp and bend parts of the wire, and cannot continuously bend multiple sections of the wire.
