Problems solved by technology

However, the increase of the spring structure makes the overall thickness of the beads thicker and the length longer. The increase in the thickness of the beads makes it difficult to reduce the diameter of the wire saw; the increase in the length of the beads reduces the density of the beads on the wire saw and the degree of bending is limited. , not suitable for sleeve operation on small-diameter runners

Embodiment 1

[0040] refer to figure 1 As shown, a diamond bead provided in this embodiment has and only has a diamond matrix 10, and the diamond matrix is ​​a matrix with only a diamond working layer; that is, in the prior art, the diamond working layer is generally prepared on a steel pipe , steel pipe as a support seat. However, in this embodiment, the steel pipe is removed, and there is only the matrix of the diamond working layer, that is, there is and only one diamond matrix 10 . The diamond matrix 10 has a through hole 11 , and the inner wall of the diamond matrix 10 surrounding the through hole 11 is also recessed to form a thread groove 12 .

[0041] More specifically, the cross-section of the thread groove 12 is square, which is convenient for subsequent preparation of diamond wire saws, such as figure 2 As shown, the cladding layer 30 can penetrate into the thread groove 12 more easily, and the opening of the square thread groove 12 is large enough. The connection of the part...

Embodiment 2

[0045] refer to image 3 As shown, the present embodiment provides a kind of preparation method of diamond beads, comprising the steps of:

[0046] A1, a helical coil 31 is provided, and the outer surface of the helical coil 31 is covered with an isolation layer 32, such as Figure 4 shown.

[0047] More specifically, in this embodiment, the cross-sectional shape of the isolation layer 32 is a square structure. During preparation, a mold can be prepared. The mold has a helical channel with a square section. The helical coil 31 is placed in the helical channel, and then injected into the isolation layer. Glue, the isolation layer 32 covering the outer surface of the helical coil 31 is obtained after the isolation glue is cured. Adopting the isolation layer 32 with a square cross section, the cross section of the thread groove 12 of the follow-up diamond matrix 10 is also square; to facilitate the follow-up preparation of the diamond wire saw, the cladding layer 30 can more ea...

Embodiment 3

[0059] refer to Figure 7 As shown, the present embodiment provides a kind of preparation method of diamond beads, comprising the steps of:

[0060] A1, providing a screw rod 40 with thread 41 on the outer peripheral surface, such as Figure 8 shown; and the outer peripheral surface of the screw 40 is covered with an isolation layer (not shown).

[0061] A2, prepare the diamond substrate 10 directly on the peripheral surface of the screw rod 40, such as Figure 9 , Figure 10 shown.

[0062] Specifically, in this step, since the screw 40 is a solid structure with sufficient support, the diamond matrix 10 is formed on the outer peripheral surface of the screw 40 by direct hot pressing and sintering when preparing the diamond matrix 10 . This preparation method is simpler and faster. Of course, in other embodiments, the green diamond substrate can also be cold-pressed onto the screw 40 by cold pressing, and then shaped by high-temperature sintering.

[0063] A3, removing t...

Abstract

The invention provides diamond string beads, a diamond wire saw and a preparation method of the diamond string beads. The diamond string beads are provided with only one diamond base body, the diamond base body is provided with a through hole, and the inner wall of the through hole enclosed by the diamond base body is sunken to form a thread groove. When the wire saw is prepared, the string beads are directly embedded into a coating layer through the thread grooves, and the axial anti-movement and circumferential anti-rotation effects of the string beads can be well achieved; meanwhile, an existing spring structure is omitted, the thickness can be reduced to be smaller, and the diameter of the rope saw can be made to be smaller; and the length is reduced, the string bead density on the wire saw is greatly increased, the cutting efficiency of the wire saw is effectively improved, the bending capacity of the wire saw is better, and the wire saw can be well arranged on a small-diameter rotating wheel in a sleeving mode for operation. The method for preparing the diamond string beads is simple and ingenious in preparation step and does not damage the diamond matrix.

Description

technical field [0001] The invention relates to the field of wire cutting, in particular to a diamond bead, a diamond wire saw with the diamond bead and a preparation method of the diamond bead. Background technique [0002] Diamond wire saw, also known as diamond wire, refers to the use of electroplating or resin bonding methods to fix diamond abrasives on wires for wire cutting. In the prior art, a diamond wire saw generally includes a wire rope, a plurality of beads strung on the wire rope, and a coating layer arranged on the outer surface of the wire rope to fix the beads. In order to prevent the beads from moving in the axial direction and The rotation in the circumferential direction of rotation, as disclosed in CN103144202A, discloses a diamond wire saw with a spring inside the bead and its manufacturing method. The spring is set in the bead to limit the reinforcement. In this way, it can effectively prevent the bead on the shaft. Movement in the direction of movemen...
