Description

Technical Field

[0001] The utility model relates to a novel diamond bead structure and a mold thereof, belonging to the field of diamond beading. Background Art

[0002] Traditional diamond tools suffer from uneven and chaotic diamond distribution, leading to uncoordinated interaction between abrasive grains during the cutting process. This can lead to uneven consumption, which not only affects cutting efficiency but also makes tool life uncertain. Due to the disordered arrangement of diamonds, some diamond abrasive grains may not be effectively utilized, resulting in a waste of resources. Furthermore, interference between diamonds can lead to premature shedding or breakage of diamond particles, further reducing diamond utilization.

[0003] The utilization rate of diamonds in existing diamond bead structures is low. Due to the segregation of diamonds, some diamonds gather together and fall off without being fully utilized. In some areas, there are too few diamond particles, resulting in uneven consumption and eccentric wear. The diamond concentration at the front and back ends of the bead cutting is the same, but during the cutting process, the front end of the bead is the first to contact and wear, which easily causes the taper of the bead, affecting the cutting life and later efficiency. The entire bead is a uniform cylindrical shape, which has high friction resistance during use, poor chip holding, chip removal and cooling capabilities, and low bead processing efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a new diamond bead structure and its mold to solve the problems of low utilization rate of diamonds in the existing diamond bead structure. Due to the segregation of diamonds, some diamonds gather together and fall off without being fully utilized. In some areas, there are too few diamond particles, resulting in uneven consumption and eccentric wear. The diamond concentration at the front and rear ends of the bead cutting is consistent, but during the cutting process, the front end of the bead is the first to be contacted and worn, which easily causes the taper of the bead to affect the cutting life and later efficiency. The entire bead is a uniform cylindrical shape, which has high friction resistance during use, poor chip holding, chip removal and cooling capabilities, and low bead processing efficiency.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a new type of diamond bead structure is provided, which comprises: at least one bead ring; a substrate, wherein at least one bead ring is connected to the surface of the substrate by sintering; wherein, several layers of diamond particle layers are arranged in an orderly manner on the bead ring, and the front end of the bead ring forms a front bead cutting part, and the rear end of the bead ring forms a rear bead cutting part through the diamond particle layers; walnut shell-shaped particles, wherein at least one layer of walnut shell-shaped particles for carrying water and removing chips is provided in the middle section of the bead ring, and the front and rear of the walnut shell-shaped particles are connected to the front bead cutting part and the rear bead cutting part respectively.

[0006] Furthermore, in order to prevent the taper of the beads from affecting the cutting life and later efficiency, the number of diamond particle layers in the front bead cutting part is greater than the number of diamond particle layers in the rear bead cutting part. The number of diamond particle layers in the front bead cutting part is 4-6 layers, and the number of diamond particle layers in the rear bead cutting part is 2-4 layers.

[0007] Furthermore, in order to improve the firmness of the connection, the beaded ring is connected to the base body by hot pressing and sintering.

[0008] Furthermore, in order to improve the sharpness during the cutting process and increase the drainage and chip holding function, the particle size of the walnut shell-shaped particles is 10-30 meshes.

[0009] Furthermore, in order to be suitable for various sizes of cutting workpieces, the outer diameter of the beaded ring is 3.5-12.5 mm and the width is 5-8 mm.

[0010] Furthermore, in order to improve cutting efficiency, the diamond concentration in the front bead cutting part is 25-40%, and the diamond concentration in the rear bead cutting part is 15-30%.

[0011] Furthermore, in order to reduce frictional resistance and improve chip holding, chip removal and cooling capabilities, the beaded ring is a cylindrical structure.

[0012] According to another aspect of the present invention, a vacuum adsorption mold is provided. The vacuum adsorption mold is used to produce the diamond bead structure by cold pressing with sand and hot pressing and sintering. The vacuum adsorption mold is provided with orderly arranged holes corresponding to the diamond particle layer.

[0013] The beneficial effects of the present invention are as follows: the diamond bead structure not only improves the utilization rate of diamonds through the orderly arrangement of diamonds, but also improves the cutting efficiency and life, and at the same time ensures that the diamond concentration at the cutting front end is higher, avoiding the formation of taper during the bead cutting process that affects the cutting life, and the walnut shell-shaped particles in the middle are carbonized into graphite particles after sintering. During the cutting process, they are easy to fall off to form holes, which can carry water, not only enhancing the chip removal and cooling capabilities of the beads, but also playing a friction-reducing role, thereby improving the working efficiency of the beads.
