Description

Technical Field

[0001] This utility model relates to the field of flanging and bending technology, specifically to a device for flanging and bending stamped parts without springback angle. Background Technology

[0002] Stamping is a process in which external force is applied to sheet metal, strip, tube or profile by a press and a die to cause separation or plastic deformation, thereby obtaining a workpiece of the required shape and size. Springback-free flanging is a processing method that, through process optimization or die design, allows the flanged and bent parts to achieve the target angle without additional compensation after forming. Its core is to eliminate the springback phenomenon caused by the elastic deformation of the material in traditional bending processes.

[0003] Chinese Patent Publication No. CN115889534A, authorized on April 4, 2023, discloses a processing apparatus for a springback-free flanged stamping part, relating to the processing and manufacturing of automotive parts. The apparatus includes a punch; a first bearing surface with a horizontal orientation and a second bearing surface with an angle of α (87°) on the projected plane; a die positioned above the punch and moving up and down to press a flat stamping part firmly onto the punch; the stamping part having a pressure-bearing section and a bending section, the pressure-bearing section abutting against the punch under the action of the die, and the bending section extending outwards and suspended relative to the punch; and a flanged insert; the flanged insert is movably positioned relative to the punch; when the flanged insert moves, it acts on the bending section of the stamping part, causing the bending section to first bend vertically and then continue to bend inwards to fit against the second bearing surface. By improving the design of the processing equipment, the straight flanging process and the oblique flanging process are integrated into one processing equipment; this process method not only improves efficiency, but also improves the quality of parts and reduces debugging costs.

[0004] Existing flanging and bending devices place the stamped parts directly without effectively limiting their movement. During the stamping process, the stamped parts are prone to shifting and warping due to stress, and there is a possibility of springback. As a result, the stamped parts do not fully reach the bending angle, which affects the processing quality and fails to meet the usage requirements. Utility Model Content
