Description

Technical Field

[0001] This invention relates to the field of diamond wire cutting equipment technology, and specifically to a horizontal wire cutting method. Background Technology

[0002] The cutting principle of diamond wire cutting machines is similar to that of a bow saw. A high-speed rotating and reciprocating winding wheel drives the diamond wire in a reciprocating motion, creating a relative grinding motion between the diamond wire and the workpiece being cut, thereby achieving the cutting purpose. Multi-wire cutting technology is currently one of the most advanced silicon wafer processing technologies in the world. Its principle is to use a high-speed moving steel wire to drive a cutting blade attached to the wire to rub against hard and brittle materials such as semiconductors, thereby achieving the cutting effect. Throughout the process, the diamond wire is guided by multiple guide rollers to form a wire mesh on the main wire roller. Compared with other technologies, multi-wire cutting technology has advantages such as high efficiency, high capacity, and high precision. However, currently used conventional diamond wire cutting devices still have significant drawbacks. During diamond wire cutting, cutting debris falls and causes wire breakage; the winding wheel replacement process is complex, requiring disassembly of the winding mechanism, resulting in significant time waste.

[0003] In wire EDM, the winding wheel is a crucial component of the machine tool. It changes the direction of the diamond wire. A typical U-shaped wire EDM head consists of four pairs of winding wheel mechanisms. During production, the diamond wire frequently contacts the winding wheels, causing them to wear easily and requiring replacement after a period of use, thus increasing the consumption of the cutting wire. Currently, the winding wheels are generally mounted on the same drive shaft. During maintenance and replacement, all components of the winding wheel mechanism must be disassembled, making disassembly and maintenance difficult and significantly increasing production costs.

[0004] Patent CN209971164U discloses a three-wire horizontal strip cutting machine. Its moving cutting system includes a base plate, a self-driven spindle, a guide wheel frame, a first support column, a second support column, and a third support column. The first, second, and third support columns are all mounted on the base plate, and each set of the first, second, and third support columns is installed in a rotationally symmetrical manner. The self-driven spindle is mounted on each set of the first, second, and third support columns. The guide wheel frame is mounted on the base plate and has guide wheels. The base plate has wire feeding holes and workpiece holes. However, the existing moving cutting system of the three-wire horizontal strip cutting machine suffers from the problem of difficulty in winding the diamond wire around the guide wheel frame.

[0005] In addition, after prolonged use, the grooves on the rollers will wear down, affecting cutting accuracy. When it is necessary to replace the grooves on the rollers, the rollers' movement distance needs to be calibrated. Usually, the movement distance needs to be measured and determined manually by the operator, which is not only inefficient but also poses a risk of mechanical injury during operation.

[0006] When changing the support post at the end of the online cutting process, the crystal rod may sag slightly due to its own weight and the limited number of support points, which directly affects the straightness of the product cutting. Therefore, there is an urgent need for a crystal rod tail support mechanism for the cutting machine that can correct the problem of slight crystal rod sag according to the actual cutting situation.

[0007] In diamond wire cutting equipment, the winding and take-up processes of the diamond wire are a major challenge that limits the efficiency of the equipment. Poor winding conditions on the winding and take-up mechanisms will lead to unstable tension fluctuations in the diamond wire during high-speed cutting, and may even cause wire breakage. This not only affects the cutting accuracy, but also wastes a lot of manpower, resources, and time.

[0008] Based on the above, this invention proposes a horizontal wire cutting method that can effectively solve the above problems. Summary of the Invention

[0090] To enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present patent.

[0091] Example:

[0092] like Figures 1 to 23As shown, a horizontal wire EDM machine includes a frame, which comprises at least four gantry columns distributed at the four corners of the frame and several base beams and top beams connected at both ends to two different gantry columns respectively; a gear and rack transmission mechanism is provided at the top of the frame; a wire EDM structure is provided inside the upper part of the frame; the upper part of the wire EDM structure passes through the top of the frame and is connected to the gear and rack transmission mechanism, so that the wire EDM structure can move back and forth along the gear and rack transmission mechanism under the drive of external power; a crystal rod support mechanism is provided inside the lower part of the frame; the crystal rod support mechanism includes a tail end support mechanism provided on one side of the frame and at least one liftable support pile provided at the bottom of the frame; a wire take-up and unwinding chamber is provided on the outer side of the frame, and the wire take-up and unwinding chamber is provided with a wire winding and tensioning mechanism; the wire EDM structure and the wire winding and tensioning mechanism are indirectly connected through the cutting wire.

[0093] The horizontal wire cutting equipment of this invention has a simple structure and is easy to use. The crystal rod support mechanism accurately positions and fixes the crystal rod to be cut, ensuring cutting precision. The split-type winding wheel mechanism at the bottom of the wire cutting structure is equipped with an anti-cutting edge sheath falling device to prevent the edge sheath from falling and hitting the diamond wire during the cutting process, causing wire breakage and improving the stability of the equipment during operation and increasing work efficiency. A slot correction mechanism is set on the cutting head, making slot changing operation simple and with high slot changing positioning accuracy, improving work efficiency while reducing the risk of mechanical injury. The split-type winding wheel mechanism has internal ventilation... The device is easy to install using end face teeth, is lightweight, and features a split roller design consisting of two sets of rollers rotating in opposite directions. This allows the cutting forces to cancel each other out during crystal rod cutting, minimizing vibration of the workpiece. The device employs a combination of a crystal rod support mechanism, a wire cutting structure, and a winding tensioning mechanism, all electrically connected to an integrated control box. This results in high cutting efficiency and precision for the horizontal wire cutting equipment, improving crystal rod cutting and forming efficiency while reducing worker workload.

The split-type winding wheel mechanism comprises four sets, arranged in a "U" shape at the front end of the cutting head frame. The reversing winding mechanism is located at the rear end of the cutting head frame. A single diamond cutting wire is wound around the V-groove of the roller, and the reversing winding mechanism reverses its direction, ultimately winding it into a 15mm x 15mm wide, 45° front-to-back interlaced wire mesh, transforming single-wire cutting into multi-wire cutting and improving production efficiency. The upper end of the cutting head frame is also equipped with a groove-changing and correction mechanism.

[0095] As a further preferred embodiment, the split-type winding wheel mechanism includes: a drive shaft, a driven shaft, a flexible coupling, a servo drive motor, a drive roller, and a driven roller. Both the drive shaft and the driven shaft are equipped with bushing housings. One end of the flexible coupling is sleeved on the drive shaft, and the other end is sleeved on the servo drive motor. The drive roller is connected to the drive shaft via a right-side tooth, and the driven roller is connected to the driven shaft via a left-side tooth. The right-side and left-side teeth include working tooth surfaces and non-working end faces. In actual use, the servo drive motor drives the drive shaft through the flexible coupling... The drive shaft rotates, driving the drive roller to rotate via the right-end teeth. As the drive roller rotates, it drives the diamond wire to cut in the predetermined direction. The driven roller rotates under the influence of the diamond wire, but in the opposite direction. Because the drive and driven rollers rotate in opposite directions, their cutting forces cancel each other out, minimizing vibration of the workpiece. The separate winding wheel mechanism in the same group has two rollers rotating in opposite directions, significantly reducing the number of rollers, lowering costs, and ensuring smooth movement, achieving multi-wire cutting with a single wire.

[0096] During the installation of the aforementioned split-type winding wheel mechanism, such as... Figure 7 As shown, the driving roller is mounted on the drive shaft via the right end face teeth. After the working and non-working end faces of the right end face teeth mesh with each other, the driven roller is installed. After both are installed, as shown... Figure 8 As shown, rotating the end face teeth locks them together with their working surfaces facing each other. During disassembly and maintenance, only rotating the end face teeth is needed to separate them, which improves the efficiency of maintenance work.

[0097] As a further preferred embodiment, both the right end face tooth and the left end face tooth are provided with a locking device. The locking device includes a locking bolt and a threaded through hole. After installation, the end face teeth are locked by the locking device to prevent the equipment from being misaligned due to centrifugal force during operation.

[0098] As a further preferred embodiment, the bushing housing is provided with a bearing cavity, and an angular contact bearing is installed in the bearing cavity. The inner ring of the angular contact bearing is in close contact with the drive shaft, and the outer ring of the angular contact bearing is in close contact with the bearing cavity, thereby reducing friction through the angular contact bearing.

[0099] As a further preferred embodiment, the angular contact bearing is provided in two sets, including an inner angular contact bearing and an outer angular contact bearing. Providing two sets of bearings reduces friction and extends the service life of the equipment.

[0100] As a further preferred embodiment, a bushing is provided between the two sets of angular contact bearings.

[0101] As a further preferred embodiment, a locking nut is fixed to the outer thread of the outer angular contact bearing.

[0102] As a further preferred embodiment, the bushing housing is provided with a threaded hole, and a bearing cover is provided on the outside of the bushing housing. The bearing cover and the threaded hole can be connected and fixed by a bolt.

[0103] By combining the above technical solutions, the bearing can be fixed in the bushing box. When replacing the bearing, it is only necessary to remove the bolt from the threaded hole to remove the bearing cover and replace the bearing directly, which simplifies the equipment maintenance steps.

[0104] As a further preferred embodiment, a waterproof sealing ring is also provided inside the bushing housing. Since wire cutting requires cutting fluid for cooling and lubrication, there is a possibility that cutting fluid and profile debris may splash into the bushing housing during the cutting process, which may reduce the life of the bearing or drive shaft. The waterproof sealing ring can effectively prevent the above situation from occurring.

[0105] As a further preferred embodiment, the reversing winding mechanism includes a connecting plate, a reversing bracket column is provided behind the connecting plate, and a reversing bracket is installed on the reversing bracket column. The reversing bracket is characterized in that it has a stepped mounting surface, a fixed frame is hinged to the stepped mounting surface, and a reversing guide wheel is installed on the fixed frame, including an aluminum disc and a fixed shaft. The aluminum disc is installed on the fixed shaft, and the fixed shaft is installed through the fixed frame and has an angle adjustment device at its tail end.

[0106] This invention mounts the reversing guide wheels on a stepped mounting surface of the reversing bracket. The staggered mounting of the guide wheels on the reversing bracket via different stepped surfaces prevents interference between the guide wheels during diamond wire winding. Furthermore, wire threading can be performed directly without bypassing the guide wheel bracket, improving threading efficiency. The aluminum disc is mounted on a fixed shaft via a deep groove ball bearing, converting the rolling friction between the aluminum disc and the fixed shaft into friction between the disc and the deep groove ball bearing, extending the service life of the reversing guide wheels. Simultaneously, the tail-end angle adjustment device allows for fine-tuning based on the actual winding angle of the diamond wire, reducing vibration between the diamond wire reversing winding mechanism and the cutting mechanism, extending the service life of both mechanisms, and improving cutting accuracy.

[0107] As a further preferred embodiment, a rubber wheel is fitted onto the outer surface of the aluminum disc, and the rubber wheel is tightly fitted to the aluminum disc. The rubber wheel is made of polyurethane. Polyurethane rubber wheels are wear-resistant, which can effectively improve the service life of the equipment, and can be quickly replaced when worn to a certain extent.

[0108] As a further preferred embodiment, the reversing support column is provided in four sets, and each set of reversing support column is provided with two sets of reversing supports.

[0109] As a further preferred embodiment, a plurality of stepped mounting surfaces are provided on the set of commutation brackets, and a commutation guide wheel is correspondingly mounted on each stepped mounting surface. The direction of the commutation guide wheel is perpendicular to the tangent direction of the diamond wire, and there is a two-degree difference between each commutation guide wheel in each group.

[0110] As a further preferred embodiment, a wire inlet and outlet device is further provided at the rear end of the connecting plate. The wire inlet and outlet device includes a wire inlet frame, a mounting frame, and a wire inlet and outlet guide wheel. The wire inlet frame is hinged to the rear end of the connecting plate, and the wire inlet and outlet guide wheel is mounted at the tail end of the wire inlet frame through the mounting frame.

[0111] Combined with the above technical solutions, the diamond wire exits from the wire winding and unwinding bin, passes through the wire inlet and outlet device provided at the rear end of the connecting plate, and then is repeatedly wound around the cutting mechanism through the commutation winding mechanism to form a "mouth"-shaped cutting wire net, achieving the purpose of multi-wire cutting with a single diamond wire. The wire inlet and outlet device changes the inlet direction of the diamond wire, making the inlet of the diamond wire more stable.

[0112] As a further preferred embodiment, the groove changing and deviation correcting mechanism includes a sliding device and an adjusting device. The cutting head skeleton is slidably arranged at the lower end of the connecting plate through the sliding device. An adjusting device is fixedly connected between the cutting head skeleton and one side of the connecting plate. The adjusting device includes: an adjusting shaft seat, an adjusting screw, an adjusting gasket, and a fixing block. The adjusting shaft seat is fixedly installed on one side of the cutting head skeleton. One end of the adjusting screw is fixed on the fixing block, and the other end is fixed with an adjusting column. The adjusting gasket can be inserted between the adjusting column and the fixing block. The adjusting column and the adjusting screw can lock the adjusting shaft seat and the fixing block. During actual use, each time the groove is changed, the center of the diamond wire net will shift. During the adjustment process, first rotate the adjusting column to separate the adjusting shaft seat and the fixing block, insert or remove the adjusting gasket to make the diamond wire in a horizontal state in the wire groove, prevent the center of the wire net from shifting and causing damage to the equipment, and then rotate the adjusting column to lock the adjusting shaft seat and the fixing block. Only by rotating the adjusting column and inserting or removing the corresponding adjusting gasket can the function of moving the diamond wire from the original wire groove to other wire grooves be realized. The operation is simple, and the function of correcting the center of the wire net during groove changing is realized.

[0113] As a further preferred embodiment, the sliding device includes a linear track and a linear bearing. The linear track is arranged at the upper end of the cutting head skeleton, and a linear bearing is slidably arranged on the linear track. The upper end of the linear bearing is fixedly connected to the connecting plate. Through the linear track and the linear bearing, the direct friction between the cutting head skeleton and the connecting plate is converted into rolling friction between the linear track and the linear bearing, reducing the friction coefficient and extending the service life of the equipment.

[0114] In a further preferred embodiment, the upper end of the adjusting shaft seat is provided with a U-shaped groove, and the adjusting screw is disposed within the U-shaped groove. The adjusting screw is further fixed by the U-shaped groove.

[0115] As a further preferred embodiment, the adjusting shim is inverted "U"-shaped, and its thickness is the distance of one slot interval on the roller. Since the shim thickness is the same as the slot interval on the roller, a corresponding number of adjusting shims are inserted or removed each time a slot is changed, based on the actual slot change position. This ensures high positioning accuracy during slot changes, keeping the diamond wire and slot relatively horizontal, avoiding the need for manual correction of the wire mesh center after each slot change, and improving work efficiency.

[0116] As a further preferred embodiment, the adjusting shims are provided in five sets.

[0117] As a further preferred embodiment, a waterproof bellows cover is connected between the cutting head frame and the connecting plate. The waterproof bellows cover effectively prevents cutting coolant and debris generated during the cutting process from being thrown into the cutting head by the high-speed moving wire mesh, thus preventing structural damage.

[0118] During the slot-changing process, the adjustment device is adjusted to make the cutting head skeleton move relative to the connecting plate. Each movement is equal to the width of one or more slots. The operation is simple and the slot-changing positioning accuracy is high, which improves work efficiency and reduces the risk of mechanical injury.

[0119] As a further preferred embodiment, the two sets of split-type winding wheel mechanisms located at the bottom are equipped with a crystal rod edge anti-drop device. By adding the crystal rod edge anti-drop device, the edge material is prevented from falling and hitting the diamond wire during the cutting process, causing wire breakage, thereby improving the stability of the equipment during operation and increasing work efficiency.

[0120] As a further preferred embodiment, the upper end of the reversing winding mechanism is also provided with a tension adjustment mechanism. By adjusting the tension mechanism, the tension inside the diamond wire mesh is balanced, the additional tension is reduced, the breakage rate is lowered, and the maximum cutting tension and cutting speed of the diamond wire are increased.

[0121] As a further preferred embodiment, the front end of the cutting head frame is also provided with a lubrication and cooling device. The lubrication and cooling device is arranged in a "U" shape inside the split winding wheel mechanism, and spray nozzles are equidistantly arranged on the lubrication and cooling device. The lubrication and cooling device effectively reduces the temperature of the diamond wire mesh, washes away the waste chips generated by cutting, extends the service life of the diamond wire, and improves cutting accuracy.

[0122] As a further preferred embodiment, the tail end support mechanism includes: a support base, a first support plate, and a second support plate. The first support plate is fixed on the support base. The tail end of the first support plate is provided with a pin through hole, and two sets of pin through holes are provided. The tail end of the second support plate is provided with a pin groove, which can be placed between the two sets of pin through holes and connected by a pin. The second support plate can rotate clockwise or counterclockwise around itself, so that the angle between itself and the first support plate changes. The front end of the second support plate is provided with a U-shaped support plate. In actual use, the tail end of the crystal rod is placed on the U-shaped support plate. According to the change of the level of the crystal rod during the actual processing, the second support plate is rotated to raise or lower the relative height of the tail end of the crystal rod, so as to achieve the purpose of keeping the crystal rod in the required horizontal position during the processing.

[0123] As a further preferred embodiment, the second support plate is also provided with a height adjustment device, which includes a locking bolt, an adjusting bolt, and an adjusting threaded hole. The locking bolt is inserted into the first support plate, and the adjusting bolt passes through the adjusting threaded hole and contacts the upper surface of the first support plate. Rotating the adjusting bolt causes it to move up and down within the adjusting threaded hole. During the rotation, the second support plate rotates clockwise or counterclockwise around the pin slot, raising or lowering the relative height of the crystal rod tail end. The locking bolt can limit the maximum adjustment angle to prevent over-adjustment. The height adjustment device simplifies the adjustment process while improving the adjustment accuracy.

[0124] As a further preferred embodiment, the second support plate is also provided with a left-right adjustment device, which includes a fixing block connected to the front end of the second support plate via a lead screw. An adjusting nut is also provided on the lead screw, which can move axially along the lead screw, thereby moving the fixing block. Depending on the size of the crystal rod being processed, the adjusting nut is rotated to move the fixing block axially along the lead screw until the crystal rod is locked. This design is highly versatile and compatible with different crystal rod sizes.

[0125] As a further preferred embodiment, the left and right adjustment device is provided in two sets, which are respectively located on the left and right sides of the front end of the second support plate, providing double-sided support to prevent loosening during processing.

[0126] As a further preferred embodiment, a timing belt slot is provided above the left and right adjustment device, and a toothed connecting groove is provided at the lower end of the timing belt slot. A timing belt is inserted into the timing belt slot, and the timing belt and the toothed connecting groove fit together. The timing belt fixes the crystal rod and reduces the friction between the crystal rod and the fixing structure.

[0127] As a further preferred embodiment, a clamping mechanism is provided above the timing belt slot. The clamping mechanism includes a clamping block, a clamping handle, and a clamping buckle. The clamping block is set above the timing belt slot by a pin and can rotate clockwise or counterclockwise around it. A semi-circular groove is provided above the clamping block. The clamping handle is provided with a fixing through hole and a connecting through hole. The clamping handle is connected to one side of the clamping block through the fixing through hole. The clamping buckle is inverted "U" shape and its upper part is engaged with the semi-circular groove. The clamping buckle is rotatably connected in the connecting through hole by a pin. During use, pulling the clamping handle upward causes the clamping handle to move upward, causing the clamping buckle to disengage from the semi-circular groove, thus unlocking the clamping block and the timing belt slot. When locking is required, pulling the clamping handle downward causes the clamping handle to press down and engage with the semi-circular groove. This simplifies the replacement and maintenance steps of the timing belt and has a simple structure.

[0128] In a further preferred embodiment, the winding tensioning mechanism includes: a take-up and release bin, a release mechanism, and a take-up mechanism. The release mechanism is located at the left end of the take-up and release bin, and the take-up mechanism is located at the right end. The release mechanism includes a release wheel, a release servo motor, a release and alignment module, a release tensioning module, and an inlet guide wheel. The take-up mechanism includes a take-up wheel, a take-up servo motor, a take-up and alignment module, a take-up tensioning module, and a take-up guide wheel. The diamond wire sequentially enters the cutting chamber through the release wheel, the release and alignment module, and the release tensioning module for cutting. After cutting, it returns to the take-up wheel via the take-up tensioning module and the take-up and alignment module. The diamond wire achieves stability and rigidity when entering and exiting the bin through the take-up and alignment module and the take-up tensioning module, improving cutting efficiency.

[0129] As a further preferred embodiment, both the wire feeding module and the wire take-up module include a lifting cylinder, a fixed base, and a wire guide wheel. The lifting cylinder is fixed to the left and right ends of the wire feeding and take-up chambers and is horizontal to the wire feeding and take-up reels. The fixed base is slidably sleeved on the lifting cylinder and can be vertically raised and lowered on the lifting cylinder. The wire guide wheel is fixed inside the fixed base. During the wire feeding and take-up operation, the wire feeding reel rotates according to predetermined parameters, releasing the diamond wire on the reel. The wire guide wheel, driven by the lifting cylinder, performs a cyclic linear motion, thereby enabling the diamond wire to enter the cutting chamber in a single-layer manner. Similarly, the take-up reel rotates according to predetermined parameters, and the wire guide wheel, driven by the lifting cylinder, performs a cyclic linear motion, thereby ensuring that the diamond wire returning from the cutting chamber is tightly wound on the take-up reel in a single-layer manner.

[0130] As a further preferred embodiment, an infeed guide wheel is provided above the wire tensioning module, and the direction of the infeed guide wheel is perpendicular to the wire guide wheel.

[0131] As a further preferred embodiment, a take-up steering guide wheel is provided above the take-up tensioning module, and the direction of the take-up steering guide wheel is perpendicular to the direction of the take-up guide wheel.

[0132] Combining the above technical solutions, the diamond wire automatically bends via guide wheels when entering or exiting the wire feeding / receiving compartment, forming a good angle for entering and exiting the wire and avoiding the risk of accidental detachment.

[0133] As a further preferred embodiment, a deviation correction device is provided between the wire feeding reel and the wire feeding and arranging module. When the wire feeding reel feeds the wire, if the wire feeding direction of the wire feeding reel is opposite to the movement direction of the wire feeding and arranging module, the deviation correction device receives the pressure change and sends an electrical signal, causing the wire feeding and arranging module to adjust the wire feeding direction, thereby achieving deviation correction, making the wire feeding process smooth and preventing the diamond wire from breaking.

[0134] As a further preferred embodiment, both the wire feeding tensioning module and the wire feeding tensioning module include a tensioning motor, a tensioning arm, and a tensioning guide wheel. The tensioning arm is connected to the output end of the tensioning motor and can rotate in a predetermined direction along the output end. The tensioning guide wheel is located at the distal end of the tensioning arm. By balancing the tension inside the diamond wire mesh through the tensioning mechanism, the additional tension is reduced, the wire breakage rate is lowered, and the maximum cutting tension and cutting speed of the diamond wire are increased.

[0135] The present invention also provides a horizontal wire cutting method, comprising the following steps:

[0136] 1) Place the crystal rod into the horizontal wire cutting equipment and fix one end of the crystal rod with the tail end support mechanism. Then, as needed, fix the remaining part of the crystal rod in segments at intervals using at least one liftable support pile.

[0137] 2) Preset wire cutting parameters through the integrated control box;

[0138] 3) Through external power and transmission via the gear and rack transmission mechanism, the wire cutting structure is driven to move along the gear and rack transmission mechanism to the position to be cut on the crystal rod;

[0139] 4) Activate the wire cutting structure and the winding tensioning mechanism to perform wire cutting on the crystal rod;

[0140] 5) Repeat steps 2) to 4) at least once to complete the cutting of the crystal rod; or repeat steps 3) to 4) at least once to complete the cutting of the crystal rod.

Both the drive shaft and the driven shaft are equipped with bushing housings. One end of the flexible coupling is sleeved on the drive shaft, and the other end is sleeved on the servo drive motor. The drive roller is connected to the drive shaft via a right-side tooth, and the driven roller is connected to the driven shaft via a left-side tooth. Both the right-side and left-side teeth include working tooth surfaces and non-working end faces. The rollers of this invention are mounted on the rotating shaft via end-face teeth, allowing for easy separation during disassembly and maintenance by simply rotating them, thus improving work efficiency. Because the drive roller and driven roller rotate in opposite directions, their cutting forces cancel each other out, minimizing vibration of the workpiece.

[0144] The reversing winding mechanism of the present invention includes a cutting head frame, a reversing support column disposed behind the cutting head frame, a reversing support mounted on the reversing support column, the reversing support having a stepped mounting surface, a fixing frame hinged to the stepped mounting surface, a reversing guide wheel mounted on the fixing frame, the reversing guide wheel including an aluminum disc fixing shaft, the aluminum disc mounted on the fixing shaft, the fixing shaft being mounted through the fixing frame and having an angle adjustment device at its tail end. The present invention uses a single diamond wire to wind around the cutting mechanism to form a "U"-shaped cutting wire mesh, achieving the purpose of multi-wire cutting; the winding mechanism achieves staggered installation of the reversing guide wheel on the reversing support through different stepped surfaces, preventing mutual interference between the reversing guide wheels during diamond wire winding, and allowing wire threading without bypassing the guide wheel support, thus improving threading efficiency.

[0145] The slot-changing and correction mechanism of the present invention includes: a cutting head frame, a connecting plate, and a sliding device. The cutting head frame is slidably disposed at the lower end of the connecting plate via the sliding device. An adjustment device is fixedly connected to one side of the cutting head frame and the connecting plate. The adjustment device includes: an adjustment shaft seat, an adjustment screw, an adjustment shim, and a fixing block. The adjustment shaft seat is fixedly installed on one side of the cutting head frame. One end of the adjustment screw is fixed to the fixing block, and the other end is fixed to an adjustment column. The adjustment shim can be inserted between the adjustment nut and the fixing block. The present invention allows for the movement of diamond wire from its original slot to another slot simply by rotating the adjustment column and inserting or removing the corresponding adjustment shim. This is simple to operate, provides high slot-changing positioning accuracy, improves work efficiency, and reduces the risk of mechanical injury.

[0146] The tail end support mechanism of the present invention raises or lowers the relative height of the tail end of the profile according to the change in the horizontality of the tail end during the actual processing, so as to achieve the purpose of keeping the profile at the required horizontality during the processing.

[0147] The winding tensioning mechanism of the present invention achieves stability and rigidity when the diamond wire enters and exits the chamber through the winding and tensioning module and the winding module, thereby improving the cutting efficiency; the winding guide wheel is equipped with a correction device that can correct the position of the cutting line according to the winding situation.

[0148] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
