Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Example one

Referring to fig. 1 to 3, the present embodiment provides a diamond wire saw with an improved service life, including a wire 30, a plurality of beads strung on the wire 30, and a coating layer 40 disposed on an outer surface of the wire 30 to fix the beads; specifically, the cord 30 is a steel wire cord with good hardness; the coating layer 40 is a plastic filling layer, can be filled in an injection molding mode, and is good in combination degree. Of course, in other embodiments, the invention is not limited thereto.

The bead includes base 10 and diamond base member 20, base 10 is hollow tubular body, diamond base member 20 sets up in the surface of base 10, and diamond base member 20 is outer narrow interior wide structure, and the axial dimension of the outside 201 of diamond base member 20 is less than the axial dimension of interior limit (the limit that links to each other with base 10 promptly). So set up, along with the extension of cutting time, the diameter of diamond base member 20 is diminishing gradually, but grow in axial dimensions, lets the diamond base member 20 of string of beads effectively keep stone material overall pressure like this, and the sharpness that also is effectively keeps to the life of string of beads has been prolonged.

Further, in the present embodiment, the size of the diamond matrix 20 gradually widens from outside to inside, and as shown in fig. 1 and fig. 2, the cross section of the diamond matrix 20 is in a trapezoidal structure, i.e., an upper base (i.e., a short side) of the trapezoid is an outer side 201 of the diamond matrix 20, a lower base (i.e., a long side) is an inner side of the diamond matrix 20, and an oblique side between the outer side 201 and the inner side of the diamond matrix 20 is a flat side, i.e., an end face 202 of the diamond matrix 20 is an oblique plane. Thus, as the diameter of the diamond matrix 20 gradually becomes smaller, the axial size gradually becomes larger, so that the sharpness is always effectively maintained; the performance is more stable. Of course, in other embodiments, the structure that the size of the diamond matrix 20 gradually widens from the outside to the inside is not limited to the structure that the cross section is trapezoidal, and for example, the straight inclined side of the trapezoid in fig. 1 may be changed into an arc side with a certain radian, that is, as shown in fig. 4, the end surface 202 of the diamond matrix 20 is an arc surface, and thus, the sharpness of the diamond matrix 20 can be effectively maintained all the time.

Further, in this embodiment, the diamond substrate 20 completely covers the base 10, that is, the inner edge of the diamond substrate 20 completely covers the base 10; the axial length of the working layer can be extended to the maximum extent.

Further, in the present embodiment, the end surface of the base 10 of the bead is an inclined end surface, and the coating layer 40 abuts against the inclined end surface of the base 10. With the arrangement, the coating layer 40 can limit the beads in the circumferential rotating direction, so that the beads are prevented from rotating during cutting; the stability is better.

Further, in this embodiment, both the outer surface and the inner surface of the base 10 have spiral grooves, the spiral groove defining the outer surface is an outer spiral groove 11, the spiral groove of the inner surface is an inner spiral groove 12, and the diamond matrix 20 is filled in the outer spiral groove 11 of the outer surface of the base 10; the coating layer 40 is filled in the inner spiral groove 12 of the inner surface of the base 10. In this way, the bonding fastness of the diamond base 20 to the base 10 in the axial direction, and the bonding fastness of the base 10 and the coating layer 40 in the axial direction can be improved to a large extent; further improving the cutting capability of the diamond wire saw.

Further, in this embodiment, the base 10 is a spring, and the spring is a seamless spring with spring wires attached to each other in a free state. The spring is provided with an outer spiral groove 11 and an inner spiral groove 12; no additional processing is needed; the preparation is simple. Of course, in other embodiments, the structure of the base is not limited thereto.

Example two

The diamond wire saw with the service life prolonged provided by the embodiment is approximately the same as the diamond wire saw with the service life prolonged in the first embodiment in structure, and the difference lies in that: in this embodiment, the diamond substrate 20 is gradually widened from the outside to the inside. As shown in fig. 5, a step 2021 is formed between the outer edge 201 and the inner edge of the diamond matrix 20, that is, the cross section is in a "convex" shape, so that the dimension of the outer layer 21 of the diamond matrix 20 in the axial direction is always the same, the diameter of the outer layer 21 is reduced during consumption, but the axial dimension is not changed, the cutting sharpness is not supplemented during the process, but the outer layer 21 is completely consumed, and then immediately contacts the inner layer 22, the pressure returns to the normal value, and the service life is also prolonged.

More specifically, the number of steps on the end surface of the diamond base 20 is not limited to one, and may be a plurality of continuous steps, such as three continuous steps 2021 shown in fig. 6, so that the axial dimension of the diamond base 20 increases layer by layer.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
