[0002] The template-free forming device for special-shaped sheet metal parts is a mold-free progressive forming device. The technology uses a CNC tool knife to process metal sheets along a predetermined path. The entire process is based on local plastic deformation and does not require a mold.

[0003] During the use of the existing template-free forming device for special-shaped sheet metal parts, the metal sheet needs to be placed on a hollow loading platform, and the edge of the metal sheet is clamped and fixed by a cylinder. However, in actual use, if the impact force on the metal sheet is large, the cylinder is prone to slipping, and the cylinder is prone to leakage after long-term use, resulting in unstable clamping, which in turn affects the overall sheet metal effect.
