Description

Technical Field

[0001] The utility model relates to the field of jewelry processing, in particular to a diamond-shaped needle for jewelry processing. Background Art

[0002] During the jewelry processing, jewelry of different materials and shapes needs to be punched, polished, cut and other processes. The drilling of jewelry in the jewelry processing process is usually carried out with a diamond-shaped needle. The diamond-shaped needle is a kind of punching needle formed by installing broken diamonds on the top of the drill bit. The hardness of diamond is relatively hard and can effectively drill jewelry of different materials, increasing the convenience of the jewelry processing process.

[0003] Most of the existing diamond-shaped needles are difficult to make and are installed and connected to the drill bit by gluing. The broken diamonds installed on the top of the drill bit are easy to fall off during use, resulting in reduced efficiency in the jewelry processing process. It is necessary to design a diamond-shaped needle for jewelry processing to solve the above-mentioned problems. Utility Model Content

[0006] A diamond-shaped needle for jewelry processing, comprising a drill bit and broken diamonds, wherein a fitting groove is arranged on the upper part of the drill bit, metal tin is arranged inside the fitting groove, the metal tin wraps the broken diamonds, and a wrapping edge is arranged around the top of the drill bit; the drill bit is used to install the broken diamonds, the fitting groove is used to wrap the broken diamonds, the metal tin is used to connect the broken diamonds and the drill bit, and the wrapping edge is used to embed the metal tin and the broken diamonds;

[0007] Furthermore, the top diameter of the drill bit is 1.7 mm, the diameter of the fitting slot is 1.3 mm, the depth is 1 mm, and the diameter of the wrapping edge is 0.2 mm;

[0008] Furthermore, the bottom diameter of the crushed diamonds is 1 mm.

[0009] The utility model has the following beneficial effects:

[0010] In the utility model, the top of the drill bit is firstly grinded and smoothed on a grinding machine, and the grinded drill bit is annealed and allowed to cool naturally, which can increase the hardness of the drill bit and prevent it from breaking during the process. Then the drill bit is clamped and tightened to increase the stability during the subsequent processing. A wave needle with a diameter of 1.3mm is used to grind the top of the drill bit to form a fitting groove with a depth of 1.5mm. A broken diamond with a bottom diameter of 1mm is taken out and placed in the fitting groove, so that the broken diamond can be placed in the fitting groove (2); secondly, the edge position of the fitting groove is cut into 4 equal parts, and the cutting is performed. The depth is 0.5mm, and the melted metal tin is dripped into the fitting groove, and the excess metal tin is quickly cleaned up, and the broken diamonds are placed on the upper part of the metal tin, with the tips of the broken diamonds facing up, and slightly pressed down to make them embedded in the metal tin; further, the excess overflowed and solidified metal tin is polished clean, and the wrapping edge is pinched inward with pliers to wrap the metal tin and the broken diamonds, and the edge position is polished round with a grinding wheel machine; finally, the inlaid broken diamonds are gently polished with a diamond flying saucer to make the diamond tips sharp, which is convenient for production and the broken diamonds are not easy to fall off during use.
