A manufacturing process of a natural stone double-sided convex go chess piece

Abstract

A kind of manufacturing process of natural stone double-sided convex Go chess pieces related to the technical field of Go chess pieces preparation, is characterized in that: Step 1, select black or white natural stone; Step 2, remove the loose layer on the surface of natural stone; Step 3, rough cut: Cut the natural stone blocks into long strips with a width specification of 24±0.5mm and a thickness of 15±1mm; step 4, blank making: cut the long strips of natural stone with a specification of 24±0.5mm and a thickness of 15±1mm into 24±0.5 ×24±0.5×15±1mm square blank; step 5, mark the center point of the two ends of the blank: draw the diagonal line of the square end surface of the square blank, and mark the intersection point of the two diagonal lines; step 6, use the centering The clamping device clamps the center position of the two square end faces of the square billet, and then uses the centering clamping device to clamp the square billet and cooperates with the corresponding grinding machine to grind the square billet into a disc shape; safety hazard issues.

Description

technical field [0001] The invention relates to the technical field of preparation of go pieces, in particular to a production process of natural stone double-sided convex go pieces. Background technique [0002] As known, chess pieces are cultural equipment with entertainment and intelligence development, and the main types include Chinese chess, chess, go, shogi, backgammon or flying chess, etc. The above-mentioned chess pieces are widely used and loved by the public, especially go, It has a long history in China, and it is a kind of confrontational game between two people. The mass base of Go is quite broad, and people can often be seen playing chess in streets and alleys, parks, units and various activity venues; the development of Go is based on China, Southeast Asia, dominated by Japan and South Korea, is gradually developing into South Asia, Europe and the United States and other countries. From ancient times to the present and at home and abroad, Go pieces are divid...

Problems solved by technology

From ancient times to the present and at home and abroad, Go pieces are divided into materials: agate, jade, ceramics, stone, shells, wood, plastics, etc. Before the Ming Dynasty, most of them used natural black and white materials and directly cut them into flat or flat shapes with knives. Shell-shaped, polished chess pieces, there are many Go pieces made of agate, jade, and stone. This kind of chess pieces feel smooth and are very popular among chess players. Traditional natural stone Go pieces can be roughly divided into two types, one is direct handwork. Grinding and forming, the other is to grind the natural stone now, and then add other ingredients and fire it into shape; the direct manual grinding and forming method wastes materials on the one hand, and the yield is low, on the other hand, the manual grinding method has potential safety hazards , and the technical requirements for operators are high, and the phenomenon of grinding deviation often occurs, and the pass rate is low; the method of grinding natural stone and then adding other ingredients to form it after firing is high in the utilization rate of natural stone, but this method The process of the method is more complicated, and the production cycle is longer;

[0003] Chinese patent (notification number: CN2083059) discloses a double-sided spherical agate go piece for Go. The patent uses an ordinary grinder to manually grind the blank. On the one hand, there is a safety hazard in manual operation due to the small blank. On the one hand, manual grinding is difficult to control the grinding allowance, and it is easy to cause partial grinding, that is, the axis center of the chess pieces after grinding is offset, and the outer surface radian is not uniform
