Abstract

The utility model discloses a take chute diamond string of beads, its characterized in that: the beads are provided with 4-8 grooves in the axial direction, each groove is 8-15 degrees in the axial direction, and the inclination direction of each groove is consistent with the screwing direction of the steel wire rope. The utility model discloses a set up the chute on the string of beads, because the rotation of string of beads self when the string of beads rope saw cuts, ensure that the developments are gone up the basin and are paralleled with the direction of motion of string of beads rope, not only make string of beads chip removal, cooling capacity more abundant, reduced the area of contact of being cut the object simultaneously such as string of beads and stone material, concrete, reduce the cutting resistance, improve the efficiency of string of beads rope saw, realize high-speed cutting.

Description

Diamond string bead with chute

Technical Field

The utility model relates to a stone material, concrete cutting tool technical field, concretely relates to take diamond string of beads structure of chute.

Background

The diamond beaded rope is a wire saw machining tool integrating high hardness of diamond and high flexibility of a steel wire rope, is the most advanced stone mining equipment in the world at present, is widely applied to stone mining and machining, demolition and trimming of reinforced concrete buildings, and machining of brittle and hard materials such as glass, and is also applied to the work in special fields such as maintenance of seabed components, demolition of nuclear power plants, and the like, has a series of advantages of high resource utilization rate, small environmental influence, high machining efficiency, simplicity in construction, low noise, low dust, low pollution and the like, and is hardly comparable to other types of tools.

However, the existing diamond bead has the problems that the exposure of the diamond of the bead is slow, namely, the cutting time is long, the frictional resistance is large, the chip removal and cooling capacities are poor, the processing efficiency of the bead is low and the like in the use process.

SUMMERY OF THE UTILITY MODEL

To the not enough above, the utility model provides a scheme that technical problem adopted is:

a novel diamond bead structure comprises a bead carcass working layer and a bead matrix, and is characterized in that the working layer is provided with an inclined groove in the axial direction;

furthermore, the chute is characterized in that the number of the chutes is 4-8;

further, the chute is characterized in that the angle of the chute is 8-15 degrees;

furthermore, the chute is characterized in that the chute is semicircular, and the radius of the chute is 1.0-2.5 mm;

compare prior art, the utility model discloses the structure has following advantage:

1) the skewed slots are arranged on the beads, so that the dynamic water feeding grooves are ensured to be parallel to the motion direction of the bead rope due to the rotation of the beads during sawing, and the beads can be more fully discharged with chips and cooled;

2) due to the arrangement of the inclined grooves, the contact area of the beads and cut objects such as stone, concrete and the like is reduced, the cutting resistance is reduced, the efficiency of the wire saw for the beads is improved, and high-speed cutting is realized.

Detailed Description

The invention is described in detail below with reference to the drawings and specific examples:

as shown in figures 1 and 2, the novel diamond bead structure consists of a bead carcass 1 and a bead base body 3, wherein the bead carcass 1 is provided with chutes 2, the number of the chutes 2 is different according to the bead diameter, and the number of the chutes 2 is 4-8, and the angle is changed according to the width and the diameter of the bead carcass and is 8-15 degrees. The radius of chute 2 also is relevant with the diameter of string of beads, and the string of beads diameter is big more, and the radius of corresponding chute is also big more, between 1.0 ~ 2.5 mm.

When the beaded rope is sawed, the whole rope can rotate along the direction opposite to the steel wire rope weaving direction, a tire body on the beaded rope also rotates around the axis of the tire body, a chute on the tire body is consistent with the rotation of the beaded rope, and the angle of the chute corresponds to the rotation angle of the beaded rope and the span and the diameter of the beaded tire body, so that the dynamic water feeding groove is ensured to be parallel to the motion direction of the beaded rope, the smooth drainage and chip removal of the beaded rope are facilitated, and the whole rope is cooled more fully; meanwhile, due to the existence of the inclined groove, the contact area of the bead string and cut objects such as stone, concrete and the like is reduced, the cutting resistance is reduced, the efficiency of the bead string rope saw is improved, and high-speed cutting is realized.

The novel string bead with the chute is prepared by the following method:

the side plates 4 and the partition plates 5 of the graphite mould shown in figure 3 are respectively provided with a semicircular chute 2, a certain number of side plates 4 and middle partition plates 5 are combined together according to the size of a mould frame and are placed into a pressure head 6 shown in figures 4 and 5, the pressure head 6 is provided with a blind hole 7 for inserting a bead string substrate 3, an inserting rod 8 shown in figures 6 and 7 is inserted into the chute 2 between the side plates 4, the middle partition plates 5 and the pressure head 6, the upper part and the lower part of the inserting rod 8 are milled with circular arcs (approximate can be replaced by straight lines) with the radius being consistent with that of the pressure head 6 and the radius being R, and the height of the middle part is consistent with the width of the bead string body 2. And pouring a mixture of metal powder and diamond, putting the mixture into a pressure head 6, performing hot-pressing sintering in a hot-pressing sintering machine according to a corresponding process, cooling, removing the mold, and taking out the inserted rod 8 to obtain the diamond bead to be grooved.

Preferably, the plunger 8 is made of metal, so as to greatly prolong the service life of the plunger.

Finally, it is noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the protection scope of the claims of the present invention.
