Description

Technical Field

[0001] The utility model relates to the technical field of diamond wire processing, in particular to a diamond wire grinding brush device and a processing production line. Background Art

[0002] Diamond wire, also known as diamond cutting wire, is a linear superhard material cutting tool in which diamond micropowder particles are uniformly bonded to a busbar (typically a high-carbon steel wire). As shown in Chinese invention patent publication number CN 114672861 A, the patent discloses an electroplated diamond wire saw with controllable abrasive distribution and a method for manufacturing the same. The electroplated diamond wire saw with controllable abrasive distribution comprises a busbar, an abrasive region, and an abrasive-free region. The abrasive regions are arranged on the busbar in a regular or irregular pattern, with equal or unequal spacing, or randomly distributed. An abrasive-free region is formed between adjacent abrasive regions. The busbar is the base material of a wire saw, rope saw, or ring-shaped wire saw and is made of a conductive, high-strength material. The abrasive-free region provides the wire saw with a larger chip volume, enhancing coolant transport.

[0003] To obtain this wire saw, it is necessary to add a selective shielding process before the conventional diamond wire saw sanding process and an optional shielding removal process after the sand consolidation / thickening process. It is more troublesome to form an abrasive-free area by shielding first and then removing, and there is a lack of corresponding equipment when using mechanical brushes to remove local abrasives.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0027] Example 1: Figure 1As shown, the utility model discloses a diamond wire grinding and brushing device, comprising a brush wheel 1 and a driving mechanism 2. A plurality of clusters of brush filaments 11 are provided on the brush wheel 1, and a wire-passing channel 3 for the diamond wire 4 to pass through is provided on the outside or inside of the brush wheel 1. The wire-passing channel 3 is an imaginary or actual straight channel, and its length direction is the passage direction of the diamond wire 4. The brush filaments 11 are made of hard brush filaments 11 such as steel wires. One end of the brush filaments 11 is fixedly connected to the brush wheel 1, and the other end is a freely set free end 111. The driving mechanism 2 is used to drive the brush wheel 1 to rotate around the center line of the wire-passing channel 3. When the brush wheel 1 rotates, the free end 111 of each brush filament 11 can enter the wire-passing channel 3 as the brush wheel 1 rotates to grind the diamond wire 4.

[0028] When the wire passing channel 3 is arranged on the outside of the brush wheel 1, as one of the cases, the driving mechanism 2 includes a first motor 21 and a first rotating shaft 22. The first motor 21 is a speed-regulating motor that is intermittently turned on. One end of the first rotating shaft 22 is driven and connected to the first motor 21, and the other end is fixedly connected to the brush wheel 1.

[0029] The diamond wire 4 to be brushed is a conventional diamond wire 4 that has been sanded but not yet sand-consolidated. Abrasive particles are already attached to the busbar substrate, but the attachment is not strong. This brushing device can remove most of the abrasive particles without pre-masking, thereby obtaining a low-abrasive particle area 42 with similar functionality to that of the prior art. Depending on the brushing requirements, the low-abrasive particle area 42 can be further brushed into an abrasive-free area 42 by increasing the length of the brush filament 11 entering the wire passage 3 and the brushing time.

[0030] Specifically, when the diamond wire 4 is brushed, the diamond wire 4 to be brushed can be fed into the wire channel 3 along the length of the wire channel 3, and the drive mechanism 2 is turned on to drive the brush wheel 1 to rotate around the wire channel 3. When the brush wheel 1 rotates, the diamond wire 4 can continue to move or temporarily stop moving. Driven by the brush wheel 1, the hard brush filaments 11 continuously enter and exit the wire channel 3 and brush the diamond wire 4. Under the action of the brush filaments 11, the loosely attached abrasive particles fall off, thereby forming a low-abrasive particle area / no-abrasive particle area 42 on the diamond wire 4. After brushing, the drive mechanism 2 can be turned off, and the diamond wire 4 can be driven to travel a certain distance along the wire channel 3, thereby retaining some segments of abrasive particles, corresponding to the formation of a high-abrasive particle area 41. In this way, by cyclically opening and closing the drive mechanism 2, a diamond wire 4 with a high-abrasive particle area 41 and a low-abrasive particle area / no-abrasive particle area 42 arranged alternately can be formed. At the same time, by controlling the speed of the first motor 21, the on / off time of the first motor 21, the routing speed of the diamond wire 4 and other parameters, the lengths of the high-abrasive area 41 and the low-abrasive area / no-abrasive area 42 can be adjusted accordingly.

[0031] Preferably, the brush wheel 1 and the drive mechanism 2 are each provided with two groups, and the brush wheel 1 and the drive mechanism 2 are connected in a one-to-one correspondence. The two groups of brush wheels 1 are relatively arranged on both sides of the wire-passing channel 3 and rotate in the same direction. The two groups of brush wheels 1 can brush in both directions to fully brush and remove abrasive particles on both sides of the diamond wire 4. The clusters of brush filaments 11 used for brushing abrasive particles are arranged around the outside of the brush wheel 1, and the clusters of brush filaments 11 are arranged at intervals to speed up the brushing speed. The clusters of brush filaments 11 can also be arranged equidistantly or unequally along the length direction of the wire-passing channel 3 to form equidistant or unequally arranged low-abrasive / no-abrasive areas 42. Of course, only a single group of drive mechanisms 2 can also be provided to synchronously drive two or more groups of brush wheels 1 through various means such as gear transmission, belt transmission, and chain transmission, so that each group of brush wheels 1 can be brushed at the same time.

[0032] This brushing device can be used with a slightly modified version of an existing diamond wire 4, resulting in a diamond wire 4 with alternating high-abrasive grain zones 41 and low-abrasive / absent-abrasive grain zones 42. Due to the controlled addition of the low-abrasive / absent-abrasive grain zones 42, the diamond wire 4 has ample space to accommodate cutting chips and carry coolant during cutting operations, effectively improving cooling and cutting efficiency while reducing chip clogging. This significantly extends the cutting life of the diamond wire 4, especially when cutting large materials, and reduces unit wire consumption.

[0033] Although the total number of abrasive grains is reduced compared to the conventional diamond wire 4, resulting in an increase in the average load of a single abrasive grain, the average sawtooth height of the abrasive grains is increased due to the presence of the low-abrasive grain area / no abrasive grain area 42, which helps to make more full use of the cutting ability of the abrasive grains. In addition, the reduction in overall sand consumption is also conducive to reducing the preparation cost of the diamond wire 4.

[0034] like Figure 2-3 As shown, the above-mentioned drive mechanism 2 can also adopt another structural form. Specifically, the drive mechanism 2 includes a base 23, a second motor 24, a second rotating shaft 25, a transmission wheel 26 and an annular rotating seat 27. Among them, the second motor 24 is fixedly connected to the base 23, and a speed-regulating motor can also be adopted, and it is turned on intermittently according to the brushing demand. The transmission wheel 26 is driven and connected to the second motor 24 through the second rotating shaft 25, and is driven to rotate by the second motor 24 and the second rotating shaft 25. The brush wheel 1 is fixedly connected to the annular rotating seat 27. The annular rotating seat 27 is rotatably connected to the base 23, and the annular rotating seat 27 is driven and connected to the transmission wheel 26, and the annular rotating seat 27 can be driven to rotate by the transmission wheel 26. In this embodiment, the transmission wheel 26 and the annular rotating seat 27 are connected by gear transmission, and the outer side of the annular rotating seat 27 has gear teeth that mesh with the transmission wheel 26. The wire-passing channel 3 passes through the inner cavity of the annular rotating seat 27 and the base 23 . When the annular rotating seat 27 rotates, the brush wheel 1 fixed on the annular rotating seat 27 can rotate around the wire-passing channel 3 .

[0035] In one embodiment, the brush wheel 1 is in the shape of a cylinder with both ends open. The brush wheel 1 and the annular rotating seat 27 are arranged vertically, and the internal cavities of the brush wheel 1 and the annular rotating seat 27 are connected and correspond to each other, so that the wire passage 3 can pass through. The wire passage 3 passes through the internal cavity of the brush wheel 1, the internal cavity of the annular rotating seat 27, and the base 23 in sequence. The brush wheel 1 can be integrally formed and arranged on the annular rotating seat 27.

[0036] The brush filaments 11 for grinding are arranged on the inner side of the brush wheel 1. In general, the brush filaments 11 can be evenly arranged along the circumference of the brush wheel 1. When grinding, the brush filaments 11 can rotate around the wire channel 3 as the brush wheel 1 rotates, that is, they rotate radially around the diamond wire 4 to fully grind the abrasive particles. Figure 4 As shown in the figure, the brush wires 11 are arranged only in a small range along the circumference of the brush wheel 1. As the annular rotating seat 27 rotates and cooperates with the continuous axis of the diamond wire 4, a continuous, uninterrupted, spiral low-abrasive area / no-abrasive area 42 can be formed on the diamond wire 4.

[0037] like Figure 5-6 As shown, the brush wheel 1 and the annular swivel seat 27 can also be connected in a detachable manner so that the brush wheel 1 with different lengths of brush filaments 11 can be replaced according to the brushing needs, or replaced after long-term use and wear. Preferably, a first mounting hole 12 is provided on the brush wheel 1, and a second mounting hole 271 corresponding to the position of the first mounting hole 12 is provided on the annular swivel seat 27. The first mounting hole 12 and the second mounting hole 271 are arranged correspondingly up and down, and one of them is a strip hole. A threaded fastener 28 is inserted into the first mounting hole 12 and the second mounting hole 271. The threaded fastener 28 locks the brush wheel 1 to the annular swivel seat 27. In this embodiment, the first mounting hole 12 is a strip hole, and the second mounting hole 271 is a conventional bolt hole. Before the threaded fastener 28 is tightened, the brush wheel 1 can be moved along the long axis direction of the strip hole, i.e., the first mounting hole 12, to adjust the length of the brush filament 11 entering the wire channel 3, so as to adjust the brushing depth and degree accordingly to meet different brushing needs. Preferably, the brush wheel 1 is provided with multiple ones, and is evenly arranged along the circumference of the annular rotatable seat 27. The strip holes, i.e., the first mounting holes 12, are radially arranged on the annular rotatable seat 27 with the wire channel 3 as the center, so as to evenly adjust the spacing between the free ends 111 of the brush filaments 11.

[0038] Example 2: Based on the above-mentioned Example 1, the present invention also discloses a diamond wire processing production line, including a sanding module and a sand consolidation module. The sanding module is used to attach diamond abrasives to the steel wire substrate, and the sand consolidation module is used to consolidate the diamond abrasives on the steel wire substrate. The above-mentioned diamond wire grinding brush device is connected between the sanding module and the sand consolidation module.

[0039] Through this production line, the diamond wire 4 can be brushed after sanding before the abrasive grains are firmly attached, and then the diamond wire 4 can be sand-fixed without the need for pre-shielding treatment. Diamond wire 4 with a high-abrasive grain area 41 and a low-abrasive grain area / no abrasive grain area 42 can be produced. The preparation process is relatively simple and easy to implement.

[0040] In summary, the diamond wire brushing device and diamond wire 4 processing production line provided by the present invention can meet various brushing needs and process the diamond wire 4 with a plurality of abrasive grain areas 41 and a few abrasive grain areas / no abrasive grain areas 42 arranged alternately to improve the performance of the diamond wire 4.

[0041] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details of the present invention are within the scope of protection of the present invention without departing from the spirit and scope of the present invention as defined in the appended claims.
