Background

The diamond string bead wire saw is suitable for cutting and processing various hard materials, is mainly applied to the fields of stone mining, rough material shaping, plate cutting, forming cutting and processing and the like, has high material utilization rate and high cutting efficiency in material cutting, can manufacture large plates, is subjected to profiling processing, is environment-friendly and has various advantages which are difficult to compare with other types of cutters, and the diamond string bead wire saw makes great progress in the aspect of technology and market share in recent years.

In the existing diamond wire saw, in order to prevent the string movement and rotation of the diamond beads, the current method is to use plastic to wrap the steel wire rope between two adjacent diamond beads by injection molding, and to pour a part of plastic into the matrix pipe of the diamond beads, so as to prevent the diamond beads from moving in the axial direction and the radial direction. However, when the method is applied to a small-diameter diamond wire saw (particularly when the diameter of a steel wire rope of the diamond wire saw is 2-6mm, particularly 2-4 mm), the method is limited by the inner diameter of the base pipe (the gap between the steel wire rope and the base pipe is only 0.25mm), and the amount of plastic which can enter the base pipe is small, so that the effect of preventing the diamond beads from rotating is poor, after the diamond wire saw is used for a period of time, relative rotation is easy to occur between partial beads and the steel wire rope, the steel wire rope is easy to wear and break due to friction between the beads and the steel wire rope, and the service life of the wire saw is influenced.

Further, the diameter of the steel wire rope is not more than 4 mm.

Further, the diameter of the steel wire rope is 0.5-2 mm.

Furthermore, the shape of the hollow-out part is a circle or a regular polygon with more than four sides.

Furthermore, the number of the hollow parts on each fixed section is not less than one, the hollow parts are distributed on the corresponding fixed section in the radial direction, and at least one hollow part on one fixed section and at least one hollow part on the other fixed section are arranged in a staggered mode in the radial direction.

Furthermore, the hollow parts are distributed on the base pipe in a radial direction.

Furthermore, the included angle between each indentation and the axial direction of the base body tube is 0-90 degrees.

Furthermore, the included angle between each indentation and the axial direction of the base body pipe is 45 degrees.

Furthermore, the thickness of the plastic body wrapped on the steel wire rope is equal to or less than the wall thickness of the base pipe.

The utility model provides a diamond wire saw compares with prior art and has following advantage: the utility model provides a diamond wire saw forms fretwork portion on the relative both ends of base member pipe to in the plastic body of moulding plastics extends to the fretwork portion, because this plastic body has certain thickness, therefore the plastic body forms on the canned paragraph of base member pipe and prevents this base member pipe pivoted and blocks the structure, should block the structure and strengthened diamond string of beads anti-rotation ability greatly, thereby guaranteed diamond wire saw's life. In addition, because the plastic body is completely the same as the existing process of wrapping the steel wire rope between two adjacent diamond beads by plastic in an injection molding mode, the process of the existing diamond wire saw does not need to be changed, and the cost does not need to be increased.

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.

As shown in fig. 1 and 2, the utility model provides a prevent string of beads pivoted diamond wire saw, including wire rope 1 and a plurality of diamond string of beads 2 of cluster on wire rope, every diamond string of beads all establishes the base member pipe 20 on wire rope and sets up the diamond working layer 21 at the base member pipe outer peripheral face including the cover.

The base tube 20 includes a working section 201 located in the middle and fixing sections 202 located at both ends, the diamond working layer 21 is fixed on the outer peripheral surface of the working section 201 of the base tube 20 in a sintering or brazing manner, the fixing sections 202 are tube bodies without the diamond working layer 21, and the peripheral wall of the fixing sections 202 has a plurality of hollow portions 203.

The exposed steel wire rope 1 between two adjacent diamond bead strings 2 is further wrapped with a plastic body 3, and the plastic body 3 extends into the fixed section 202 and fills the hollow part 203 of the fixed section 202.

On the one hand, the plastic body 3 of filling fretwork portion 203 has the effect of preventing this base pipe 20's rotation, and on the other hand, the diamond string bead can make fretwork portion 203 atress warp (the elastic deformation of wire rope and the atress effect of base pipe) at the during operation, therefore strengthened diamond string bead 2 greatly and prevented the ability of rotating to the life of diamond wire saw has been guaranteed. In addition, because the plastic body 3 is completely the same as the existing process of wrapping the steel wire rope between two adjacent diamond beads by plastic in an injection molding mode, the process of the existing diamond wire saw does not need to be changed, and the cost does not need to be increased.

Although the diamond bead 2 provided by the embodiment can be applied to steel wire ropes with all diameters, the diamond bead 2 is more advantageous when applied to steel wire ropes with small diameters, particularly steel wire ropes with diameters not exceeding 4mm, and particularly steel wire ropes with diameters of 0.5-2 mm.

In this embodiment, the shape of the hollow portion 203 of the fixing section 202 may be a circle, a polygon, an ellipse, etc., wherein the shape of the hollow portion 203 is preferably a circle or a regular polygon with more than four sides, so that the plastic body 3 filled in the hollow portion 203 can have a better rotation-preventing effect.
