Description

Technical Field

[0001] The invention relates to the field of cutting, in particular to an electroplated combined diamond wire saw. Background Art

[0002] As is known, the components of diamond beads include a matrix and a bead core, which is part of a "diamond bead wire saw", a tool used to cut rock, concrete or other materials. Diamond beads can be divided into the following three types according to the production method: 1. Electroplated diamond beads; 2. Sintered diamond beads; 3. Brazed diamond beads.

[0003] For example, in the Chinese patent document entitled "A Diamond Bead and Its Diamond Bead Wire Saw" with the authorization announcement number CN202702415U and the announcement date 2013-01-30, a first toothed flange is provided on at least one of the two axial ends of the bead matrix of the diamond bead. When the diamond bead is made into a diamond bead wire saw, a fixing sleeve is provided on the two axial ends of the diamond bead on the wire rope, and a second toothed flange that can mesh with the first toothed flange and extends axially outward is provided on the axial end of the fixing sleeve opposite to the first toothed flange. Through the meshing of the first toothed flange and the second toothed flange and the fixing of the fixing sleeve on the wire rope, the circumferential and axial movements of the diamond bead on the wire rope are restricted, thereby fixing the diamond bead on the wire rope. When the diamond bead wire saw made in this way is used, the diamond bead and the wire rope will not rotate relative to each other, which improves the service life and processing efficiency of the wire saw and reduces the production cost.

[0004] The disadvantages of the above-mentioned prior art are that the diamond particles are continuously ground flat during operation, resulting in a decrease in the diamond pressure under the same working conditions, and the diamond cannot be effectively engraved into the material for cutting, resulting in reduced work efficiency. Summary of the invention

[0005] The object of the present invention is to provide an electroplated combined diamond wire saw to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An electroplated combined diamond wire saw comprises a plurality of diamond beads connected in series, wherein the diamond beads comprise a bead core and a matrix arranged outside the bead core, wherein the matrix comprises a plurality of diamond rings;

[0008] Gaps or spacer rings are provided between adjacent diamond rings.

[0009] In the above-mentioned electroplated combined diamond wire saw, the diamond ring is provided with multiple layers of diamond layers.

[0010] In the electroplated combined diamond wire saw, the number of the spacer rings is one less than the number of the diamond rings.

[0011] In the electroplated combined diamond wire saw, the diamond ring comprises a steel plate substrate and at least one electroplated layer.

[0012] In the electroplated combined diamond wire saw, the bead core, the diamond ring and the spacer ring are connected by one or more methods of brazing, welding and mechanical installation.

[0013] In the electroplated combined diamond wire saw, a first spring is arranged between adjacent bead cores.

[0014] In the electroplated combined diamond wire saw, an extension portion is provided on the bead core.

[0015] In the electroplated combined diamond wire saw, the bead core is provided with a compensation component for filling the gap between adjacent bead cores.

[0016] In the electroplated combined diamond wire saw, the compensation assembly comprises a lap rod slidably disposed on the bead core.

[0017] In the electroplated combined diamond wire saw, a movable groove is provided inside the bead core, a transmission plate is slidably arranged inside the movable groove, the first spring passes through the movable groove and is fixedly connected to the transmission plate, and the lap rod is also fixedly connected to the transmission plate.

[0018] In the above technical scheme, the electroplated combined diamond wire saw provided by the present invention has a spacer ring arranged in the middle that will be worn first during the wire saw cutting process, forming a concave-convex shape on the surface, that is, grooves will appear between adjacent diamond rings. The advantages of the grooves are, firstly, reducing the contact area with the cutting object during the cutting process to increase the pressure of the wire saw on the material, thereby improving the processing efficiency; secondly, the cut material will enter the groove and be discharged from both sides of the groove to improve the chip removal efficiency; thirdly, it is helpful to cool the diamond beads, thereby extending the service life of the diamond beads.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] In the description of the present invention, it is necessary to understand that the terms "center", "length", "width", "degree", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] Reference Figure 1-9 The electroplated combined diamond wire saw provided by the embodiment of the present invention comprises a plurality of diamond beads 1 connected in series, wherein the diamond beads 1 comprise a bead core 101 and a matrix 102 arranged outside the bead core 101, wherein the matrix 102 comprises diamond rings 1021; gaps or spacer rings 1022 are arranged between adjacent diamond rings 1021.

[0035] Specifically, the diamond wire saw is a tool suitable for cutting materials such as rocks and concrete, wherein a steel wire rope is arranged inside the wire rope, and a plurality of diamond beads 1 are equidistantly connected in series on the steel wire rope, and the gap between two adjacent diamond beads 1 is filled with a rubber coating layer 8, the bead core 101 is cylindrical, and the diamond ring 1021 is annular, which is arranged on the outer peripheral surface of the bead core 101. When cutting, the wire saw is wound around the material to be cut and the transmission wheel of the power source, and the friction between the wire saw and the material is driven by the power source, and the wire saw is driven to move horizontally as a whole by a horizontal driving member, and the tensioning structure can make the surface of the wire saw always fit with the material, and the material is cut by the friction between the wire saw and the material. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that a plurality of diamond rings 1021 are arranged in the axial direction of the matrix 102, and between adjacent diamond rings 1021 A spacer ring 1022 is provided, and the wear resistance of the spacer ring 1022 is less than that of the diamond ring 1021. The purpose of such a setting is that since the cutting surface of the material is uneven and the wear resistance of the spacer ring 1022 is less than that of the diamond ring 1021, during the wire saw cutting process, the middle spacer ring 1022 will be worn first, forming a concave-convex shape on the surface (a concave-convex shape will also be formed between the diamond ring 1021 and the gap), that is, grooves 13 will appear between adjacent diamond rings 1021. The advantages of the grooves 13 are that, first, the contact area with the material during the cutting process is reduced to increase the pressure of the wire saw on the material, thereby improving the processing efficiency; second, the cut material will enter the grooves 13 and be discharged from both sides of the grooves 13 to improve the chip removal efficiency; third, it is helpful to cool the diamond beads 1, thereby extending the service life of the diamond beads 1.

[0036] Preferably, the diamond ring 1021 is provided with multiple layers of diamond layers 10211. Specifically, the diamond layer 10211 is preferably three layers, and the diamond layer 10211 is composed of a medium and a plurality of diamond particles. The thickness of the three layers of diamond layer 10211, that is, the diamond layer 10211 in the present application, is three times the thickness of the diamond layer 10211 in the prior art, thereby further improving the service life of the diamond bead 1.

[0037] Preferably, the number of the spacer rings 1022 is one less than the number of the diamond rings 1021. That is, at this time, both ends of the combined structure of diamond and spacer rings 1022 are diamond rings 1021, so that the utilization rate of each spacer ring 1022 is maximized.

[0038] Furthermore, the diamond ring 1021 includes a steel plate substrate 10213 and at least one electroplated layer 10212. Specifically, the diamond layer 10211 protrudes from the surface of the electroplated layer 10212. When the electroplated layer 10212 is on one side, the electroplated layer 10212 on a single diamond bead is arranged at intervals with the steel plate substrate 10213. When the electroplated layer 10212 is on both sides, the two electroplated layers 10212 are arranged symmetrically about the steel plate substrate 10213. When making the diamond ring 1021, the steel plate substrate 10213 is placed in an electroplating tank and electroplated according to conventional processes. After electroplating, the electroplated surface is sharpened (conventionally, a grinding wheel is used to grind this surface). A working layer with the diamond layer 10211 exposed is obtained, that is, the electroplating layer 10212 and the diamond layer 10211 form a working layer, and the diamond layer 10211 protrudes out of the surface of the electroplating layer 10212, and then the excess material is removed by mechanical cutting, electric spark cutting or laser cutting, so as to obtain a diamond ring 1021 that is adapted to the size of the bead core 101, and the radial dimension of the diamond layer 10211 is larger than the radial dimension of the connection position between the coating layer 8 and it, that is, at this time, a part of the diamond layer 10211 will be exposed to improve the cutting effect.

[0039] Preferably, the bead core 101, the diamond ring 1021 and the spacer ring 1022 are connected by one or more methods selected from the group consisting of brazing, welding and mechanical installation.

[0040] Furthermore, a first spring 2 is provided between adjacent bead cores 101. Specifically, the first spring 2 is also connected in series to the wire rope and is located between two adjacent bead cores 101, and its functions are: first, to increase the axial strength of the coating layer 8 to fix the distance between adjacent diamond beads 1, thereby avoiding the overlap of diamond beads 1 (that is, two diamond beads 1 squeezed together) as much as possible; second, to reduce the overall strength of the wire saw to facilitate cutting of hard materials (such as marble).

[0041] As another embodiment of the present invention, an extension part 3 is provided on the bead core 101. Specifically, a plurality of extension parts 3 are provided, and the plurality of extension parts 3 are arranged in an array at both ends of the bead core 101, and protrude from the end of the bead core 101. The effect of such a setting is that after the coating layer 8 is injected with glue, the extension parts 3 are all inserted into the coating layer 8, so that there is a plug-in effect between the diamond beads 1 and the coating layer 8, so that the diamond beads 1 can hardly rotate relative to the coating layer 8 (similar to the structure of a non-rotating body), and so on, the extension part 3 connects the plurality of diamond beads 1 and the plurality of coating layers 8 into a whole, so that the diamond beads 1 can hardly rotate circumferentially relative to the wire rope, thereby avoiding friction between the diamond beads 1 and the wire rope as much as possible, so as to improve the service life of the wire rope.

[0042] It should be noted that if Figure 4 As shown, if the cross-section of the material to be cut is a rectangular shape with a corner (which may be an acute angle, a right angle, or an obtuse angle) (based on the convenience of description, hereinafter referred to as the material), in the early stage of material cutting, the rope saw will be over-bent, and at this time, the coating layer 8 will directly rub against the corner position, which is easy to cause damage to the coating layer 8, and then it is easy to damage the steel wire rope inside. As another embodiment of the present invention, the bead core 101 is provided with a compensation component for compensating the gap between adjacent bead cores 101. Specifically, the compensation component can be an elastic metal cylinder fixedly mounted between two bead cores 101, which is sleeved on the outside of the coating layer 8. When cutting the corner of the material, the corner position of the material will rub against the elastic metal cylinder, thereby protecting the coating layer 8 and the steel wire rope inside.

[0043] It should be noted that when cutting, even when cutting arc-shaped materials, the elastic metal tube itself will be in a stressed and bent state for a long time. When it is bent repeatedly, it is easy to cause damage to the elastic metal tube. As a replacement for the above-mentioned elastic metal tube, the compensation component includes a lap rod 4 slidably arranged on the bead core 101; a movable groove 5 is opened inside the bead core 101, and a transmission plate 6 is slidably arranged inside the movable groove 5, the first spring 2 penetrates into the movable groove 5 and is fixedly connected to the transmission plate 6, and the lap rod 4 is also fixedly connected to the transmission plate 6. Specifically, four lap rods 4 are preferably provided. In the present embodiment, the lap rods 4 are staggered with the extension part 3. A slide groove 7 is provided inside the bead core 101. The lap rods 4 are slidably arranged in the slide groove 7. The lap rods 4 protrude from the end of the bead core 101. The lap rods 4 protrude from the surface of the coating layer 8 in the radial direction. A plurality of lap rods 4 are provided. The plurality of lap rods 4 are arranged in an array on the end surface of the bead core 101. The movable groove 5 is an annular groove provided inside the bead core 101, which is connected with the slide groove 7. The transmission plate 6 is an annular plate. The transmission plate 6 is slidably arranged in the movable groove 5. The plurality of lap rods 4 are fixedly connected with the transmission plate 6. The first spring 2 passes through The side wall of the movable groove 5 is fixedly connected to the transmission plate 6, and the coating layer 8 is provided with an avoidance groove 12 adapted to the lap rod 4. The effect of such a setting is that when cutting the corner position of the material, the diamond ring 1021 will be temporarily away from the corner position, and under the action of the tensioning component, the lap rod 4 will move toward the corner position of the material, so that the lap rod 4 will contact and squeeze the corner of the material. In the subsequent movement of the rope saw, the lap rod 4 will be pulled out of the slide groove 7 under the action of friction, so that the gap between the bead cores 101 is passively compensated, and the transmission plate 6 will be driven synchronously in this process. The first spring 2 is moved and the first spring 2 is charged. When the next diamond bead 1 moves to the corner of the material, the corner of the material will be separated from the lap rod 4. At this time, the lap rod 4 is passively reset under the elastic force of the first spring 2. That is, in this embodiment, the first spring 2 is divided into a first section 201 and a second section 202. The advantages of such a setting are that, first, the first section 201 is arranged inside the movable groove 5, which can be retracted to assist the lap rod 4 in resetting. Second, the second section 202 is arranged between the gaps between adjacent bead cores 101 to improve the overall strength of the rope saw. Third, the first spring 2 and the diamond core 101 are connected. The diamond beads 1 are connected into a whole, which can improve the stringing efficiency of the wire saw (a diamond bead 1 and a first spring 2 are called a diamond unit. When stringing the diamond beads of the existing wire saw, the diamond bead 1 and the first spring 2 are alternately inserted on the wire rope, that is, when stringing a diamond unit, two stringings are required, while the diamond unit of the present application only needs one stringing). In addition, the advantage of sliding the lap rod 4 on the bead core 101 is that, firstly, since the lap rod 4 protrudes from the end of the bead core 101, the lap rod 4 will be inserted into the coating layer 8, thereby avoiding the circumferential rotation of the diamond bead 1 as much as possible.Secondly, when the lap rod 4 abuts against the corner of the material, the gap between the adjacent diamond beads 1 will be passively filled to avoid damage to the coating 8 as much as possible. Thirdly, when the first section 201 drives the lap rod 4 to reset, the gap between the adjacent bead cores 101 will be exposed, so as not to interfere with the bending process of the rope saw, which can avoid damage to the lap rod 4 due to continuous force. Fourthly, when cutting the material, a cutting gap will be generated in the material. The size of the cutting gap is approximately equal to the outer diameter of the diamond ring 1021, that is, the radial size of the cutting gap will be larger than the radial size of the coating 8. When the coating 8 passes through the cutting gap, the coating 8 will shake slightly along the width of the cutting gap. In order to solve the above problems, one of the lap rods 4 will drive the other lap rods 4 to move synchronously through the transmission plate 6 during the process, so that the lap rods 4 on both sides are in contact with the side walls of the cutting gap to protect the side of the coating 8.

[0044] As another optional embodiment of the present invention, a second spring 9 is arranged inside the slide groove 7, one end of the second spring 9 is fixedly connected to the side wall of the slide groove 7, and the other end is fixedly connected to the overlapping rod 4. When the overlapping rod 4 slides toward the outside of the slide groove 7, the second spring 9 will accumulate force. When the overlapping rod 4 moves away from the corner of the material, the elastic force of the second spring 9 is released to drive the overlapping rod 4 to automatically reset.

[0045] During the sliding of the lap rod 4, the first section 201 (or the second spring 9) will continuously accumulate force. When the pulling force of the first section 201 (or the second spring 9) on the lap rod 4 continues to increase, it is easy for the material to separate from the lap rod 4, thereby failing to fill the gap between the bead cores 101. Preferably, a slope 10 is provided on the surface of the lap rod 4 away from the central axis of the bead core 101. When the material moves along the slope 10 of the lap rod 4, the friction between the material and the lap rod 4 can be continuously increased, thereby passively balancing the increased pressure of the first section 201 (or the second spring 9), so that the friction between the lap rod 4 and the material can better drive the lap rod 4 to move along the slide groove 7.

[0046] As another embodiment of the present invention, the lap rod 4 is provided with an arc surface 11. Specifically, the end of the arc surface 11 faces the direction of the diamond bead 1, and the end shape of the avoidance groove 12 is adapted to the arc surface 11 on the lap rod 4. The purpose of such a setting is that when cutting the material, it is necessary to spray water on the cutting position to achieve the purpose of dust reduction and temperature reduction, which causes water accumulation inside the avoidance groove 12. When the lap rod 4 slides horizontally along the avoidance groove 12, the arc surface 11 at its end will squeeze the water inside the avoidance groove 12, and the accumulated water will be removed from the inside of the avoidance groove 12. Since the end of the arc surface 11 faces the direction of the diamond bead 1, the arc surface 11 at the end of the lap rod 4 plays a role of drainage at this time, so as to guide the accumulated water inside the avoidance groove 12 to the surface of the diamond bead 1, which can reduce water waste on the one hand, and better cool the diamond bead 1 on the other hand.

[0047] It should be noted that the movement direction of the rope saw is Figure 6 In the direction indicated by the middle arrow, when the wire saw starts cutting, the surface of the diamond bead 1 with the overlapping rod 4 is arranged corresponding to the surface to be cut of the material, so that the overlapping rod 4 can act on the cutting surface.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
