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.

The present application relates to the technical field of composite rod production, in particular to a composite rod forming method and a forming die thereof, the forming die comprises a soluble die, a core die and a positioning die; the soluble die is a tubular structure with an axial circular through hole, and the two ends of the soluble die are provided with slopes inclined to the axial direction, and the two ends of the two slopes are respectively provided with a limiting boss, and the two limiting bosses are respectively connected with a metal embedded part; the core die is a cylinder provided with fixing holes at both ends, the core die passes through the axial circular through hole of the soluble die, and the two ends of the core die extend to the outside of the soluble die, and the two ends of the core die are respectively provided with a first fixing hole penetrating through; the two ends of the soluble die are fixed with the core die through the positioning die; the manufacturing problem of the composite rod is solved, and the obtained composite rod has a smooth and flat outer surface, and is beautiful and practical.

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.
