Description

Technical Field

[0001] The utility model relates to the technical field of rope saws, in particular to a sharp non-uniform diameter rope saw. Background Art

[0002] Existing wire saw products all use wire saws with equal bead outer diameters. The beads are consumed synchronously during cutting, resulting in insufficient sharpness in the early stages of cutting and slow blade output. If the outer diameter of the beads is increased, although the life span is increased, the sharpness in the early stages of cutting is significantly affected. Conversely, if the outer diameter of the beads is reduced, the sharpness is increased but the life span is insufficient. Utility Model Content

[0003] The utility model provides a sharp non-uniform diameter wire saw, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] A sharp non-uniform diameter wire saw comprises a steel wire rope, beads threaded on the steel wire rope and a spacer arranged between two adjacent beads, wherein each N beads are regularly arranged on the steel wire rope as a group, and the outer diameters of the N beads increase or decrease one by one in the same direction, and the beads comprise a base body and a working layer, wherein the working layer is annularly arranged on the base body, and the working layer comprises a diamond grinding layer.

[0006] A preferred technical solution: the substrate is a cylinder.

[0007] A preferred technical solution: an opening is provided in the base body for the steel wire rope to pass through.

[0008] A preferred technical solution: a screw thread is arranged in the opening.

[0009] A better technical solution: the spacing between adjacent beads is equal.

[0010] A better technical solution: at least two beads are arranged regularly on the wire rope as a group.

[0011] A better technical solution: every two beads are arranged regularly on the wire rope as a group.

[0012] A better technical solution: every three beads are arranged regularly on the wire rope as a group.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] In the utility model, the rope saw with non-uniform bead outer diameters, in the early stage of cutting, the beads with larger outer diameters are contacted first, and because the large beads are arranged in intervals, the number of beads decreases, and the cutting state can be quickly entered, and the product has a higher sharpness. At this time, the overall outer diameter of the beads decreases, and a higher sharpness can still be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0017] Description of main reference numerals:

[0018] 1. Beads; 2. Wire rope; 3. Spacer; 11. Base; 12. Working layer. DETAILED DESCRIPTION

[0019] like Figure 1 As shown, a sharp non-uniform diameter wire saw comprises a steel wire rope 2, beads 1 threaded on the steel wire rope 2 and a spacer 3 arranged between two adjacent beads 1, three beads 1 are regularly arranged on the steel wire rope 2 as a group, and the outer diameters of the three beads 1 increase or decrease one by one in the same direction, the beads 1 comprise a base body 11 and a working layer 12, the working layer 12 is annularly arranged on the base body 11, and the working layer 12 comprises a diamond grinding layer.

[0020] Furthermore, the base body 11 is a cylinder.

[0021] Furthermore, the base body 11 is provided with an opening for the steel wire rope 2 to pass through.

[0022] Furthermore, a screw thread is arranged in the opening.

[0023] Furthermore, the spacings between adjacent beads 1 are equal.

[0024] Furthermore, four, five or six beads 1 are regularly arranged on the steel wire rope 2 as a group, and the number of beads 1 in each group can be appropriately increased according to the length of the rope saw.

[0025] Beads 1 of different sizes are produced by changing the corresponding cavity size in the mold. Beads 1 adopt a base 11 positioning method, which can ensure that the outer diameters of beads 1 are different and that beads 1 are on the same axis; the blade sharpening method adopts the traditional bead 1 blade sharpening method.

[0026] like Figure 1 As shown, beads 1 are arranged in order every 3 beads in a cycle, and the sizes of beads 1 are D1, D2, and D3, respectively, and D1<D2<D3. The first group of beads has three beads with sizes of D1, D2, and D3, and the second group of beads also has three beads with sizes of D1, D2, and D3, and so on; the size changes are also the same along the same direction, either they are arranged repeatedly in the order of D1, D2, and D3, or they are arranged repeatedly in the order of D3, D2, and D1.

[0027] In the utility model, the rope saw with non-equal diameter beads 1 has a large outer diameter. In the early stage of cutting, the beads 1D3 with large outer diameter are contacted first. Since the large beads 1 are arranged in intervals, the number of beads 1 decreases (relative to the traditional rope saw with equal diameter beads 1, the number of large beads 1 is less), and the cutting state can be quickly entered, and the product has a higher sharpness; when the beads 1 consume D2 (the second step outer diameter), the overall outer diameter of the beads 1 decreases, and the sharpness is still maintained at a high level; similarly, when the beads 1 are consumed to D1, the outer diameter further decreases, and the beads 1 still have a high sharpness, so that the rope saw can maintain good sharpness and have a longer life.

[0028] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
