Description
Technical Field
The invention relates to the technical field of polishing, in particular to a dragging and polishing method for a stone carving of a birthday mountain.
Background
The longevity stone is one of the four traditional seal stones in China, China treasure. It is glittering, translucent, greasy, colorful, natural, well-defined in color, and has the characteristics of rareness and humanity. After the quarry stone is mined, the quarry stone is mostly shown in front of people in the form of quarry stone carving, and particularly, thin carving and button printing carving are mainly used. Polishing is the last process of turning the stone carving from the original ore to the artwork, and is also the most important process. Because the birthday mountain stone carving is mostly a special-shaped curved surface, the surface shape is complicated and changeable. At present, manual polishing is mostly adopted for polishing the surface of the stone carving of the birthday mountain, and the traditional manual polishing has the following problems: the adoption of a large amount of manual polishing leads to high cost, complex polishing process, high labor intensity and uneven surface quality. Meanwhile, dust generated during polishing can be directly diffused outwards, so that the environment is polluted, and the health of workers is harmed.
The dragging type polishing is a processing method widely applied to hard alloy cutters, compared with the traditional polishing method, a polishing tool selected by the dragging type polishing is a mixed abrasive of crushed walnut shells and diamond powder, and the abrasive can adapt to various complex surfaces. However, such an abrasive is not very suitable for the gravels, because the stamp stone has soft and brittle texture, and the walnut shells and the diamond have much higher hardness than the gravels, and scratches are left on the surface during processing.
The existing drag-and-drop polishing is as follows: a dragging and polishing method of a special-shaped seal stone comprises the following steps: (1) mixing a biopolymer material with water, stirring uniformly to obtain a base solution with a concentration, adding a hard abrasive into the base solution, and dispersing uniformly to obtain biopolymer gel slurry; (2) mounting and clamping a special-shaped seal stone to be polished on a clamp of a dragging polisher; (3) and (2) placing the biopolymer gel slurry obtained in the step (1) into a container, then immersing the special-shaped seal stone to be polished, which is installed and clamped on a clamp of a dragging polishing machine, into the biopolymer gel slurry in the container, and starting the dragging polishing machine for processing. The special-shaped seal stone is immersed in the biopolymer gel slurry in the container, so that the gel slurry has high resistance, is easy to pollute during polishing and has poor reutilization property; in addition, when different shapes of seal stones are clamped, different clamps need to be replaced, the clamp is poor in universality, and the clamped parts cannot be polished due to fixing and clamping.
