Detailed Description

It should be noted that, in which numerals and letters are used as labels of the pasting method, other lines may be printed or not, the solid black line is a cut line which can be easily separated from the raw material, and the dotted line is a crease line for providing a reference for folding.

The present invention will be described in further detail with reference to the accompanying drawings 1-7: a folding polyhedron handicraft is shown in figure 1, and comprises a component I and a component II, wherein the component I is used as a base of the handicraft, and the component II is bonded on the plane of the component I; as shown in fig. 2, the component i is a polyhedron, and the plane of the component i is a regular triangle; as shown in fig. 5, the component II is a tetrahedron, the side surface of the component II is an isosceles trapezoid formed by reversely folding the sharp corner part formed by three congruent triangular side surfaces towards the interior of the tetrahedron, and the bottom surface of the component II is a regular triangle and has the same size as the plane of the component I.

As shown in fig. 3-4, the component i has 20 regular triangular faces; as shown in fig. 6-7, the component ii has a regular triangular surface, and the two triangular surfaces have the same size; and (3) coating glue on the triangular surface of the component II, adhering the glue on the component I, and adhering one component I with 20 components II to obtain a finished polyhedral handicraft.

As shown in fig. 3-4, assembly i is folded and bonded: all the dotted lines are provided with indentations, the assembly I is firstly bent preliminarily, (the surface a is the front surface of the assembly I, the surface b is the back surface of the assembly I, the folding direction is noticed), then glue is coated on the small trapezoidal surface marked as 1a, and the small trapezoidal surface is pasted on the surface 1 b. Then, the components I are obtained by sequentially adhering the components according to 2a adhesion 2b, 3a adhesion 3b and … … 9a adhesion 9 b.

As shown in fig. 6-7, assembly ii is folded and glued: and folding according to the folding direction shown by the schematic diagram of the component II according to the indentation, and in the same way, sequentially coating glue on the surface a which is the front surface of the component II and the surface b which is the back surface of the component II, and bonding the surface 2a and the surface b to obtain the component II. On subassembly II can regard as a tetrahedron basis, the closed angle portion is to the inside reverse folding of tetrahedron, has not only avoided sharp-pointed sense in the vision, and is also safer, makes holistic profile abundanter simultaneously.

The component I and the component II can adopt a die cutting process, such as: the laser knife mold process comprises the following steps: the solid line adopts a cutting knife, the dotted line adopts an indentation knife, and each component is accurately die-cut by a die-cutting machine. Or, laser die cutting process: the components are directly burnt by laser, the solid line is burn-through, the dotted line is semi-burn-through, and the sheet material can be easily folded by semi-burn-through.

Due to the error of post-stage manual manufacturing, the dotted line part can be exposed, so that the color consistent with the color of the edge of the component II can be filled, the exposure caused by the assembly error can be greatly weakened visually, and meanwhile, the blank area can be filled with any color, pattern, character or the combination of the three. For example: the polyhedral artwork is a calendar product decoration consisting of 60 different patterns and containing 60 months of 5 years.

The above embodiments are merely preferred embodiments of the present invention, and do not limit the present invention. Any extension, modification and the like of the present invention by those skilled in the art without departing from the spirit of the present invention are within the protection scope of the present invention.
