Description

Technical Field

[0001] This invention relates to the field of intelligent equipment technology for diamond wire forming and processing, and more specifically, to a diamond wire drawing roller. Background Technology

[0002] Diamond wire is generally used for cutting hard materials in industry. The diamond wire and the object being cut undergo a high-speed grinding motion to achieve the cutting purpose. Diamond wire is especially widely used in the photovoltaic field for cutting polycrystalline silicon wafers, monocrystalline silicon and crystal rods. Diamond wire can achieve high-speed cutting, with a cutting speed twice that of traditional cutting techniques.

[0003] Diamond wire drawing is achieved using drawing dies. Each die has a small conical hole. The diamond wire enters through the larger end of the conical hole and exits through the smaller end. Extrusion causes plastic deformation in the diamond wire, thus lengthening it. The diamond wire drawing process requires multiple drawing dies to be used sequentially, necessitating the use of two drawing rollers. The drawing die is positioned between the two drawing rollers. During drawing, the diamond wire is wound around the two drawing rollers by the feed roller and passes through the drawing die, finally being taken in by the take-up roller.

[0004] The drawing of diamond wire produces plastic deformation and generates a lot of heat. Metal fragments will also appear at the stretching point. If these metal fragments are not dealt with in time, they will scratch the surface of the diamond wire during subsequent stretching. After several stretching sessions, the scratches will become severe, and the wire may break. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a diamond wire drawing roller, comprising a mounting base, a self-rotating roller body on one side of the mounting base, the roller body being frustoconical, and a plurality of annular grooves I with progressively increasing diameters on the outer side of the roller body; it also includes a cleaning device disposed above the roller body, the cleaning device comprising a mounting plate fixedly connected to the mounting base, a plurality of connecting rods I rotatably mounted on the mounting plate, each connecting rod I corresponding to one of the annular grooves I, and a brush head mounted at the front end of each of the connecting rods I, the brush head extending obliquely downwards into the front side of the upper end of the annular groove I; it also includes a driving device for driving the connecting rods I to rotate; when drawing diamond wire, the diamond wire enters the annular groove I from the upper end and exits from the lower end of the annular groove I, and when the diamond wire enters the annular groove I but does not contact the inner surface of the annular groove I, the driving device drives the connecting rods I and the brush head to rotate, thereby cleaning the outer surface of the diamond wire through the brush head.

[0006] In a preferred embodiment, one side of the tower wheel body is covered with a dust collection hood, the brush head extends into the inner side of the upper end of the dust collection hood, the bottom of the dust collection hood has a dust collection chamber, one end of the dust collection chamber has a dust outlet, and a portion of the annular groove covered by the dust collection hood is connected to the dust collection chamber.

[0007] In a preferred embodiment, the drive device includes a plurality of gears corresponding to the connecting rods. The gears are fixedly installed at the end of the connecting rod away from the tower wheel body. Adjacent gears mesh with each other. One of the gears meshes with a rack. One end of the rack has a push rod. The push rod is connected to a transmission assembly. When the transmission assembly drives the push rod and the rack to move back and forth, the connecting rod and the brush head are rotated through the gears, thereby cleaning the outer surface of the diamond wire through the brush head.

[0008] In a preferred embodiment, the transmission assembly includes a placement cylinder fixedly connected to the tower wheel body. The placement cylinder is located inside the tower wheel body near the mounting base. A support frame is provided inside the placement cylinder and fixedly connected to the mounting base.

One side of the slider is connected to one end of a push rod. When the tower wheel body drives the placement cylinder to rotate, the pin and slider reciprocate inside the sliding groove through the elliptical inclined groove, thereby causing the slider to drive the rack to reciprocate.

[0009] In a preferred embodiment, the device further includes a blower, which includes a transmission assembly 2 and a duct assembly. The duct assembly includes a duct 1, one end of which is connected to a plurality of ducts 2 corresponding to the connecting rod 1. The connecting rod 1 is a hollow structure with open ends. The plurality of ducts 2 are rotatably connected to the upper end of the connecting rod 1, and the ducts 2 communicate with the interior of the connecting rod 1. The other end of the duct 1 has an air inlet. The transmission assembly 2 blows air into the duct 1 from the air inlet. The air blown into the duct 1 enters the interior of the connecting rod 1 from the upper end through the ducts 2, and then the air is blown out from the lower end of the connecting rod 1 to the brush head.

[0010] In a preferred embodiment, the transmission assembly two includes a rotating column disposed in the middle of the support frame. One end of the rotating column passes through the support frame and is rotatably connected to it. A fan blade is fixedly connected to the end of the rotating column. The fan blade extends into the interior of the air duct one and is located on the side of the support frame away from the placement cylinder. An elliptical inclined groove two is formed on the outer surface of the rotating column. A pin two is vertically movably inserted into the interior of the slider one. A spring is provided at the upper end of the pin two. The two ends of the spring abut against the pin two and the slider one, respectively. When the slider one moves back and forth, the pin two pushes the elliptical inclined groove two, thereby driving the rotating column to rotate. The rotating column drives the fan blade to rotate and blow air into the interior of the air duct one.

[0011] In a preferred embodiment, the elliptical inclined groove 2 is formed by connecting half groove 1 and half groove 2 end to end. The first end of half groove 1 is higher than the tail end of half groove 2, and the first end of half groove 2 is higher than the tail end of half groove 1. The insertion post 2 changes the direction of reciprocating movement at the point where half groove 1 and half groove 2 are connected end to end.

[0012] In a preferred embodiment, an oiling assembly is further provided on the side of the mounting base away from the tow wheel body. The oiling assembly includes an oil tank with an oil cavity for containing rust-preventive oil. A first sponge is fixedly connected to the bottom of the oil cavity, and a second sponge is attached to the bottom of the first sponge. The second sponge is fixedly connected to the oil tank. The rust-preventive oil in the oil cavity can wet and pass through the first and second sponges. After the diamond wire is drawn for the last time, the diamond wire passes between the first and second sponges, thereby applying rust-preventive oil to the surface of the diamond wire through the first and second sponges.

[0013] In a preferred embodiment, when the diamond wire passes between sponge one and sponge two, the axis of the diamond wire is parallel to the surfaces of sponge one and sponge two.

[0014] In a preferred embodiment, the system further includes a sliding assembly. The bottom end of the support frame is provided with a horizontal sliding groove. The sliding assembly includes a slider 2 that is slidably disposed inside the sliding groove 2. A post 3 is fixedly connected to the bottom of the slider 2 and is movably inserted into the sliding groove 2. A connecting rod 2 is fixedly connected to one side of the slider 2 and one end of the connecting rod 2 is fixedly connected to the oil tank.

[0015] The technical effects of this invention include:

[0016] 1. The present invention employs a cleaning device at the location where the diamond wire enters the annular groove. On the one hand, it can clean the metal debris on the surface of the diamond wire. On the other hand, it can prevent the metal debris from entering the annular groove along with the diamond wire, thus preventing the metal debris from being pressed into the surface of the diamond wire or causing the metal debris to slip on the surface of the diamond wire at the point where the diamond wire and the annular groove are pressed and contacted.

[0017] 2. This invention collects metal debris by setting up a dust collection hood, which can effectively prevent metal debris from falling directly and sticking to the surface of the diamond wire with an annular groove below, thus avoiding the problem of useless cleaning by the cleaning device.

[0018] 3. This invention achieves the purpose of maintaining the diamond wire by setting up an oiling component, namely, sponge one and sponge two are soaked with anti-rust oil and applied to the diamond wire, so as to facilitate storage and rust prevention. Attached Figure Description

Detailed Implementation

[0030] Please refer to the above as well. Figure 1-4This is a diamond wire drawing pulley, comprising a mounting base 1, a rotatable pulley body 2 on one side of the mounting base 1, the pulley body 2 being frustum-shaped, and several annular grooves 21 with progressively increasing diameters on the outer side of the pulley body 2; it also includes a cleaning device 3 disposed above the pulley body 2, the cleaning device 3 comprising a mounting plate 31 fixedly connected to the mounting base 1, and several connecting rods 32 rotatably mounted on the mounting plate 31, each connecting rod 32 corresponding to one of the annular grooves 21. Each end is equipped with a brush head 33, which extends obliquely downward into the front side of the upper end of the annular groove 21; it also includes a drive device 4 for driving the connecting rod 32 to rotate; when drawing the diamond wire 10, the diamond wire 10 enters the annular groove 21 from the upper end and exits from the lower end of the annular groove 21. When the diamond wire 10 enters the annular groove 21 but does not contact the inner surface of the annular groove 21, the drive device 4 drives the connecting rod 32 and the brush head 33 to rotate, and the outer surface of the diamond wire 10 is cleaned by the brush head 33.

[0031] The tower wheel body 2 is frustum-shaped, and the annular groove 21 gradually increases in diameter from the end with the smaller diameter to the end with the larger diameter. In use, the tower wheel body 2 needs to be mounted on the output shaft of the motor on the wire drawing equipment, and the motor drives the tower wheel body 2 to rotate. The mounting base 1 needs to be mounted on the frame of the wire drawing equipment. The purpose of the cleaning device 3 is to remove metal debris from the outer surface of the diamond wire 10.

[0032] like Figure 6 As shown, there are four annular grooves 21, and four corresponding connecting rods 32 and brush heads 33 are also provided. The connecting rods 32 correspond one-to-one with the annular grooves 21, and a brush head 33 extends into each annular groove 21. The driving device 4 for driving the connecting rods 32 to rotate can be in the form of a motor assembly. That is, each connecting rod 32 is equipped with a motor, and the output shaft of the motor is connected to the connecting rod 32. The motor drives each connecting rod 32 to rotate one by one.

[0033] The diamond wire 10 passes through the bristles of the brush head 33 when it enters the annular groove 21. Therefore, during cleaning, the connecting rod 32 and the brush head 33 rotate, and the outer surface of the diamond wire 10 can be cleaned by the bristles of the brush head 33. The brush head 33 is inserted obliquely downwards into the front side of the upper end of the annular groove 21, that is, the brush head 33 contacts the diamond wire 10 obliquely downwards. Before the diamond wire 10 enters the annular groove 21 and comes into contact with the inner surface of the annular groove 21, it can be cleaned by the brush head 33. The purpose is to prevent metal debris on the surface of the diamond wire 10 from entering the annular groove 21 and coming into contact with the surface of the annular groove 21, which would cause metal debris to be pressed into the surface of the diamond wire 10 or cause slippage on the surface of the diamond wire 10 when the inner surface of the annular groove 21 comes into contact with and squeezes the diamond wire 10. Based on this, the cleaning device 3 should be set above the tower wheel body 2, that is, at the position where the diamond wire 10 enters the annular groove 21. The cleaning device 3 should not be placed at the bottom of the tower wheel body 2, that is, at the position where the diamond wire 10 is wound out of the annular groove 21.

[0034] By installing a cleaning device 3 at the position where the diamond wire 10 enters the annular groove 21, metal debris on the surface of the diamond wire 10 can be cleaned, and metal debris can be prevented from entering the annular groove 21 along with the diamond wire 10, thus preventing metal debris from being pressed into the surface of the diamond wire 10 or causing slippage on the surface of the diamond wire 10 at the point where the diamond wire 10 and the annular groove 21 are pressed together.

[0035] When using, such as Figure 4 As shown, the diamond wire drawing roller provided in this embodiment is used in conjunction with the ordinary roller 8. The ordinary roller 8 is also frustum-shaped and has annular grooves 81 with progressively increasing diameters. The number of annular grooves 81 is consistent with that of annular grooves 21. The ordinary roller 8 is driven by a motor on the wire drawing equipment. During installation, the mounting base 1 is fixedly mounted on the frame of the wire drawing equipment with screws. The roller body 2 is driven to rotate by another motor on the wire drawing equipment. That is, the output shaft of the motor is installed at the end of the roller body 2 away from the mounting base 1, so that the motor can drive the roller body 2 to rotate. When the diamond wire 10 is wound, the wire feeding wheel of the wire drawing equipment first releases the diamond wire 10. The diamond wire 10 first passes through one of the dies on the wire drawing die 9, then enters from the upper end of the smallest diameter annular groove 21 and exits from the lower end. After changing direction through the smallest diameter annular groove 81, it passes through the wire drawing die 9 again. Then it enters from the upper end of the second annular groove 21 and exits from the lower end. After changing direction through the second annular groove 81, it passes through the wire drawing die 9 again. Through the above winding method, after winding through the annular groove 21 and the annular groove 81, the end of the diamond wire 10 exits from the largest diameter annular groove 81.

[0036] Please refer to the above as well. Figure 1-3, Figure 5 and Figure 7 One side of the tower wheel body 2 is covered with a dust collection hood 34. The brush head 33 extends into the inner side of the upper end of the dust collection hood 34. The bottom of the dust collection hood 34 has a dust collection chamber 35. One end of the dust collection chamber 35 has a dust outlet 36. The annular groove 21 covered by the dust collection hood 34 is connected to the dust collection chamber 35.

[0037] like Figure 2 and Figure 3 As shown, multiple perforations 341 are made on the side wall of the upper end of the dust collection hood 34. Each perforation 341 corresponds to an annular groove 21. Diamond wire 10 passes through the perforations 341 and then wraps around the annular groove 21. The purpose of the dust collection hood 34 is to clean the metal debris removed by the brush head 33. Figure 7 As shown, when the brush head 33 rotates, it removes metal debris from the surface of the diamond wire 10. The metal debris will enter the dust collection chamber 35 along the left side of the annular groove 21. The bottom of the brush head 33 must contact the inner surface of the annular groove 21 to prevent the removed metal debris from re-contacting the surface of the diamond wire 10 along the inner surface of the annular groove 21. Figure 7 (In the direction of rotation, the tower wheel body 2 rotates clockwise). The purpose of collecting metal debris is to prevent it from falling directly and sticking to the surface of the diamond wire 10 with the annular groove 21 underneath, so as to avoid the cleaning device 3 causing useless cleaning problems.

[0038] Refer to the instruction manual appendix Figure 6 , Figure 8 and Figure 9 The drive device 4 includes several gears 41 corresponding to the connecting rod 32. The gears 41 are fixedly installed at the end of the connecting rod 32 away from the tower wheel body 2. Adjacent gears 41 mesh with each other. One of the gears 41 meshes with a rack 43. One end of the rack 43 has a push rod 42. The push rod 42 is connected to a transmission assembly 44. When the transmission assembly 44 drives the push rod 42 and the rack 43 to move back and forth, the connecting rod 32 and the brush head 33 are rotated through the gears 41, thereby cleaning the outer surface of the diamond wire 10 through the brush head 33.

[0039] A gear 41 is installed on each connecting rod 32, and adjacent gears 41 mesh with each other. Thus, by driving just one gear 41, all connecting rods 32 can rotate. This is achieved by using a rack 43, which meshes with one of the gears 41. Specifically, it can be done as follows: Figure 3As shown, the transmission component 44, which meshes with the outermost gear 41, can be in the form of a linear cylinder. Specifically, the output end of the linear cylinder is fixedly connected to the push rod 42. By driving the push rod 42 and the rack 43 to move linearly, the gear 41 is driven to rotate, thereby achieving the purpose of driving the connecting rod 32 and the brush head 33 to rotate.

[0040] Furthermore, such as Figure 6 and Figure 9 As shown, an alternative transmission assembly 44 is provided to drive the push rod 42, eliminating the need for a linear cylinder. Specifically, the transmission assembly 44 includes a placement cylinder 441 fixedly connected to the tower wheel body 2. The placement cylinder 441 is located inside the tower wheel body 2 near the mounting base 1. A support frame 442 is provided inside the placement cylinder 441. The support frame 442 is fixedly connected to the mounting base 1. A horizontally arranged sliding groove 443 is provided at the upper end of the support frame 442. A slider 444 is slidably arranged inside the sliding groove 443. A pin 445 is fixedly connected to the slider 444. An elliptical inclined groove 446 is provided on the inner surface of the placement cylinder 441. The pin 445 is movably inserted into the elliptical inclined groove 446. One side of the slider 444 is connected to one end of the push rod 42. When the tower wheel body 2 drives the placement cylinder 441 to rotate, the pin 445 and the slider 444 reciprocate inside the sliding groove 443 through the elliptical inclined groove 446, thereby causing the slider 444 to drive the rack 43 to reciprocate.

[0041] Among them, the elliptical inclined groove 446 is set at an inclination, such as Figure 9 As shown, one end of the elliptical inclined groove 446 is close to the upper left end of the placement cylinder 441, and the other end is close to the lower right end of the placement cylinder 441. When the tower wheel body 2 rotates, it drives the placement cylinder 441 to rotate. The elliptical inclined groove 446 can push the insert post 445, so that the insert post 445 and the slider 444 move back and forth continuously in the sliding groove 443. One end of the push rod 42 passes through the sliding groove 443 and is fixedly connected to the slider 444. Thus, the slider 444 can drive the push rod 42 to move back and forth, and the push rod 42 drives the rack 43 to move back and forth.

[0042] Refer to the instruction manual appendix Figure 2 , Figure 6 and Figure 7It also includes a blower device 5, which includes a transmission assembly 51 and a duct assembly 52. ​​The duct assembly 52 includes a duct 521. One end of the duct 521 is connected to several ducts 522 corresponding to the connecting rod 32. The connecting rod 32 is a hollow structure with open ends. The ducts 522 are rotatably connected to the upper end of the connecting rod 32 and are connected to the interior of the connecting rod 32. The other end of the duct 521 has an air inlet 523. The transmission assembly 51 blows air into the duct 521 from the air inlet 523. The air blown into the duct 521 enters the interior of the connecting rod 32 from the upper end through the ducts 522 and then blows out from the lower end of the connecting rod 32 to the brush head 33. The purpose of the blowing device 5 is to blow the metal debris cleaned by the brush head 33 into the dust collection chamber 35, preventing the cleaning effect from deteriorating due to too much metal debris sticking to the bristles of the brush head 33. Specifically, the transmission component 2 51 can be a fan, which blows air into the air duct 1 521. The air enters the air duct 1 521 through the air inlet 523, and then enters each air duct 2 522 from the air duct 1 521 and is delivered to the interior of each connecting rod 1 32 from the upper end. Then, the air is blown out from the brush head 33 position at the bottom of the connecting rod 1 32, thereby blowing away the metal debris on the bristles of the brush head 33. That is, the metal debris is blown along the annular groove 1 21 into the dust collection chamber 35. The bottom of the dust collection chamber 35 has a dust outlet 36, from which the metal debris is finally discharged. A collection box can be set at the dust outlet 36 for collection.

[0043] The upper end of the second duct 522 is rotatably connected to the first connecting rod 32 because the first connecting rod 32 needs to rotate during the cleaning process, while the second duct 522 does not need to rotate. Therefore, the connection between the second duct 522 and the first connecting rod 32 can rotate, so that the rotation of the first connecting rod 32 will not affect the second duct 522.

[0044] Furthermore, such as Figure 6 , Figure 8 , Figure 9 and Figure 10As shown, another type of air-blowing transmission assembly 251 is provided, which does not require the use of a fan. Specifically, the transmission assembly 51 includes a rotating column 511 located in the middle of the support frame 442. One end of the rotating column 511 passes through the support frame 442 and is rotatably connected to it. A fan blade 512 is fixedly connected to the end of the rotating column 511. The fan blade 512 extends into the interior of the air duct 521 and is located on the side of the support frame 442 away from the placement cylinder 441. An elliptical inclined groove 513 is provided on the outer surface of the rotating column 511. A pin 514 is vertically inserted into the interior of the slider 444. A spring 515 is provided at the upper end of the pin 514. The two ends of the spring 515 press against the pin 514 and the slider 444 respectively. When the slider 444 moves back and forth, the pin 514 pushes the elliptical inclined groove 513, thereby driving the rotating column 511 to rotate. The rotating column 511 drives the fan blade 512 to rotate and blow air into the air duct 521.

[0045] Furthermore, such as Figure 10 As shown, the elliptical inclined groove 513 is formed by connecting half groove 1 5131 and half groove 2 5132 end to end. The first end of half groove 1 5131 is higher than the last end of half groove 2 5132, and the first end of half groove 2 5132 is higher than the last end of half groove 1 5131. The insert 2 514 changes the direction of reciprocating movement at the point where half groove 1 5131 and half groove 2 5132 are connected end to end.

[0046] It should be noted that during the reciprocating movement of slider 444, insert pin 514 also moves along with it. Insert pin 514 will push elliptical inclined groove 513, causing rotating column 511 to rotate. Rotating column 511 drives fan blade 512 to rotate, thereby blowing air into duct 521. The end of duct 521 is installed on the side wall of mounting base 1, and air inlet 523 is opened at the bottom of duct 521 where fan blade 512 is located.

[0047] like Figure 9As shown, the elliptical inclined groove 2 513 is inclined, with one end close to the upper left end of the rotating column 511 and the other end close to the lower right end of the rotating column 511. The horizontal distance between the leftmost and rightmost ends of the elliptical inclined groove 1 446 is equal to the horizontal distance between the leftmost and rightmost ends of the elliptical inclined groove 2 513, that is, equal to the distance when the slider 1 444 moves in one direction. During the process of the sliding drive of the rotating column 511 within the elliptical inclined groove 513 by the second insertion post 514, in order to make the rotating column 511 rotate in one direction, that is, to make the second insertion post 514 slide in one direction within the elliptical inclined groove 513, the first end of the first half-groove 5131 must be higher than the last end of the second half-groove 5132, and the first end of the second half-groove 5132 must be higher than the last end of the first half-groove 5131. Thus, when the second insertion post 514 slides to the first end of the first half-groove 5131, it will enter the last end of the second half-groove 5132. Due to the height difference, the second insertion post 514 will not slide into the first half-groove 5131 again. When the second insertion post 514 slides to the first end of the second half-groove 5132, it will enter the last end of the first half-groove 5131. Due to the height difference, the second insertion post 514 will not slide into the second half-groove 5132 again. In the above, the elastic force of the spring 515 is used to adapt to the change in the height of the second insertion post 514.

[0048] Please refer to the above as well. Figure 1 , Figure 2 , Figure 5 and Figure 6 An oiling assembly 6 is provided on the side of the mounting base 1 away from the tow wheel body 2. The oiling assembly 6 includes an oil tank 61, which has an oil cavity 62 for containing rust-preventive oil. A sponge 63 is fixedly connected to the bottom of the oil cavity 62, and a sponge 64 is attached to the bottom of the sponge 63. The sponge 64 is fixedly connected to the oil tank 61. The rust-preventive oil in the oil cavity 62 can wet and pass through the sponge 63 and the sponge 64. After the diamond wire 10 is drawn for the last time, the diamond wire 10 passes between the sponge 63 and the sponge 64, thereby applying rust-preventive oil to the surface of the diamond wire 10 through the sponge 63 and the sponge 64.

[0049] An oil inlet 65 is provided at the upper end of the oil chamber 62. The oil inlet 65 is used to add rust-preventive oil into the oil chamber 62. A cap with a small hole is threaded onto the oil chamber 62. The small hole is used to balance the air pressure inside the oil chamber 62. After the rust-preventive oil is added into the oil chamber 62, the rust-preventive oil will wet the first sponge 63. The first sponge 63 comes into contact with the second sponge 64, and the second sponge 64 will also be wetted. After the last wire drawing of the diamond wire 10, that is, when the wire drawing is completed, the diamond wire 10 (that is, the diamond wire 10 wound from the largest diameter ordinary caster wheel 8) passes through the first sponge 63 and the second sponge 64. The first sponge 63 and the second sponge 64 are wetted with rust-preventive oil, which can be applied to the diamond wire 10, thereby achieving the purpose of maintaining the diamond wire 10 and making it easier to store without rusting.

[0050] like Figure 2As shown, when the diamond wire 10 passes between sponge 1 (63) and sponge 2 (64), the axis of the diamond wire 10 is parallel to the surfaces of sponge 1 (63) and sponge 2 (64). The purpose of this parallelism is to make the deformation areas of sponge 1 (63) and sponge 2 (64) more uniform when the diamond wire 10 passes through them.

[0051] Furthermore, such as Figure 6 and Figure 9 As shown, a sliding assembly 7 is also provided. The bottom end of the support frame 442 is horizontally provided with a sliding groove 447. The sliding assembly 7 includes a slider 71 that is slidably disposed inside the sliding groove 447. A post 72 is fixedly connected to the bottom of the slider 71. The post 72 is movably inserted into the sliding groove 447. A connecting rod 73 is fixedly connected to one side of the slider 71. One end of the connecting rod 73 is fixedly connected to the oil tank 61.

[0052] Just as the placement cylinder 441 drives the slider 444 to move back and forth, during the rotation of the placement cylinder 441, the insertion post 72 can be driven by the elliptical inclined groove 446, causing the insertion post 72 to drive the slider 71 to move back and forth in the groove 447. The connecting rod 73 passes through the groove 447 and connects to the oil tank 61. The slider 71 can then drive the oil tank 61 to move back and forth through the connecting rod 73. The purpose is to make the sponge 63 and sponge 64 move back and forth relative to the diamond wire 10, so that the diamond wire 10 contacts different positions on the sponge 63 and sponge 64. This avoids the problem of insufficient rust-preventive oil application caused by the diamond wire 10 contacting the same position on the sponge 63 and sponge 64 for a long time.
