Ring diamond wire saw and manufacturing method thereof

Abstract: The invention discloses a ring diamond wire saw and a manufacturing method thereof. The ring-shaped diamond wire saw comprises a steel wire rope, a bead and a spacer which are screwed by a plurality of steel wires, and the end and the ends of the wire rope are staggered to improve the tensile strength. The connecting structures are connected together to form a ring structure, wherein the connecting structure is a structure that is not flush between the ends of the wires of the wire rope, and the connection point of the wires and the connecting points of the adjacent wires are Interlaced connection, the connection structure has good tensile strength, the cutting impact is uniform in actual work, it is not easy to be broken and opened, and the service life is long; the manufacturing method of the invention can directly produce the finished diamond wire saw made into a ring structure, Make up for the vacancies in the current market.

Main claim:

A ring diamond wire saw comprising a wire rope as a base of a wire saw, a bead that is evenly laid over the wire rope, and a spacer covering the surface of the wire rope between the beads, the wire rope being screwed by a plurality of steel wires And characterized in that: the end and the ends of the wire rope are connected together by a staggered connection structure capable of increasing the tensile strength to form an annular structure, and the connection structure is that the ends of the steel wires of the wire rope are not aligned. In the flat structure, the connection points of the respective strands of steel wire are connected to the connecting points of adjacent steel wires in an interlaced manner.

2. A ring-shaped diamond wire saw according to claim 1, wherein the connection points of the respective strands of steel wire are respectively distributed in the interval between the plurality of beads and the bead.

3 . The ring-shaped diamond wire saw according to claim 2 , wherein the wire rope is provided with a buckle sleeve for preventing the connection point from being lifted at a connection point of each strand of the steel wire, and the spacer sleeve is covered by the buckle. Set on.

4. A ring-shaped diamond wire saw according to claim 3, wherein the crimping sleeve is made of a soft copper or iron sheet and is crimped and fixed.

5. A toroidal diamond wire saw according to claim 1 or 2, wherein the joints of the strands of steel are also bonded with an adhesive that prevents the joint from lifting.

6. A ring-shaped diamond wire saw according to claim 1, wherein the connection points of the strands of steel wire are staggered in a stepped manner.

7. A ring-shaped diamond wire saw according to claim 1, wherein the connection points of the respective strands of steel wire are end-to-face connection.

8. A method of manufacturing a toroidal diamond wire saw, comprising the steps of:

1) Select a steel wire rope twisted by a plurality of steel wires to intercept the wire rope of the required length;

2) First cut off each strand of wire at one end of the wire rope, and cut off the length of one section according to the length of the distance between the ends of each strand of wire, so that the ends of each strand are not flush with each other. The end of the step is no longer truncated;

3) According to the length of the wire rope, the corresponding number of beads on the standard string of beads shall be arranged and close together on the middle section of the wire rope;

4) twisting the wire rope of step 3) according to the required number of turns in the twisting direction of each strand of steel wire, so that the wire rope itself has a torsional force, and then fixing the wire rope to prepare for the subsequent steps;

5) Select the first wire of the other end of the wire rope and connect the end point of the shortest or longest wire in step 2) to form a loop of the wire rope. Before the connection, press the length required for the circumference of the ring to firstly replace the first wire with the end of the wire. The length is cut off, and then the end face is fixedly connected to the shortest or longest wire end face in step 2), which is the first connection point;

6) Select the second wire at the other end of the wire rope, twist it around the twisting direction of the wire rope and wind it tightly with the wire connected in step 5), and then closest to the first joint point with the end point in step 2) One end of the wire is put together, and then the excess length of the second wire is cut off, and then the ends are fixedly connected;

7) The remaining strands of steel wire are connected one by one in the manner of step 6) to form a complete annular wire rope;

8) Open the injection mold, place the wire rope of step 7) into the injection mold and move all the beads one by one to the correct placement position in the injection mold, and then close the injection mold;

9) Carry out the injection molding spacer, open the injection mold and take out the diamond wire saw, that is, complete the production of the circular diamond wire saw.

The method for manufacturing a toroidal diamond wire saw according to claim 8, wherein after the step 7), the bead is distributed to the segment of the ring wire having a connection point at a predetermined interval. Each connection point is respectively distributed in the interval between the bead and the bead; then the buckle is tightly wrapped on the wire rope between the two beads corresponding to the connection point.

The method for manufacturing a circular diamond wire saw according to claim 8, wherein after the step 7), the annular wire rope is further bonded by an adhesive at a position where the connecting point is connected.
