A variable-form lighting fixture based on origami mechanics and its design method
This invention relates to the field of lighting fixtures, and discloses a variable-form lighting fixture based on origami mechanics and its design method. The invention includes an origami skeleton assembly, a light-transmitting covering layer, a light source mounting base, and a base. The origami skeleton assembly is a multi-unit origami structure that can be extended and folded. The upper end of the origami skeleton assembly is fixedly connected to the light source mounting base, and the lower end of the origami skeleton assembly is fixedly connected to the base. The light-transmitting covering layer is adhered and fixed to the outer surface of the origami skeleton assembly. The origami skeleton assembly and the light-transmitting covering layer form a deformable lighting fixture shell. The origami skeleton assembly provides a supporting foundation for shape changes and can achieve extension and folding. The light-transmitting covering layer ensures the lighting function while deforming synchronously with the skeleton. The light source mounting base and the base are fixed at both ends respectively, forming a complete lighting fixture structure that meets lighting needs while allowing for flexible shape adjustment.

A stamping die for preventing product springback
ActiveCN224600346UEnsure one-time molding in placeMeet shape requirements
This utility model discloses a stamping die for preventing product springback, relating to the field of stamping dies. It includes an upper die and a lower die; the upper die includes a punch with a first forming surface at its bottom; the lower die includes a float and a first lower die forming block and a second lower die forming block respectively located on the front and rear sides of the float. The top of the float has a second forming surface matching the first forming surface, and the bottom of the float has multiple vertical first nitrogen springs and multiple vertical guide pillars spaced apart. The guide pillars are fixedly connected to the bottom of the float, and guide sleeves are fitted onto the guide pillars and fixed below the float. The facing surfaces of the first and second lower die forming blocks are respectively set as inclined third and fourth forming surfaces. When the upper and lower dies are closed, the third and fourth forming surfaces are used to adjust the angles of the front and rear sides of the product. This utility model can automatically counteract the deformation after product springback after mold opening, ensuring that the product angle is formed in one go.
