Description

Cutting guide wheel, grooving method thereof, grooving machine and multi-wire cutting equipment

Technical Field

The invention relates to the technical field of silicon rod squaring, in particular to a cutting guide wheel, a grooving method and a grooving machine thereof, and multi-wire cutting equipment with the cutting guide wheel.

Background

When manufacturing various semiconductors and photovoltaic devices, a semiconductor ingot containing a hard and brittle material such as silicon, sapphire, or ceramic is cut and processed into wafers having a desired thickness. Since wafer dicing is an important process that restricts subsequent products, the processing requirements are increasing. At present, the multi-wire cutting technology is widely applied to industrial crystal cutting production due to the characteristics of high production efficiency, low processing cost, high processing precision and the like.

Referring to fig. 1, generally, a plurality of parallel cutting guide wheel pairs are spaced apart from each other on a multi-wire sawing machine, each cutting guide wheel pair includes two

cutting guide wheels

70a, 70b disposed oppositely (for example, disposed up and down, or disposed left and right, or disposed front and back), and a cutting wire is wound around each of the two

cutting guide wheels

70a, 70b of each cutting guide wheel pair to form a cutting wire segment 80, and the cutting guide wheel pairs are disposed in parallel, so that the cutting wire segments 80 formed between the two cutting guide wheels of the plurality of cutting guide wheel pairs are parallel to each other for performing multi-wire sawing operation on a workpiece 90.

Fig. 2 is a schematic cross-sectional view of the cutting roller of fig. 1. Referring to fig. 1 and 2, the guide cutter wheel 70 is an important part that directly affects the machining precision, and the guide cutter wheel 70 is provided with a plurality of parallel wire grooves 71 for fixing the cutting wires 80. A cutting wire 80, which can move at a high speed along with the cutter guide roller 70, is wound around the inside of each wire groove 71. In the prior art, the outer periphery of the cutter guide wheel 70 is mostly coated with polyurethane, and the quality of the polyurethane largely determines the cutting quality of the workpiece. In order to ensure the uniform thickness of the workpiece, the cutting lines need to be uniformly and stably distributed on the cutting guide wheel. And the polyurethane cutting guide wheel is provided with a groove, so that the stability of the polyurethane cutting guide wheel can be ensured.

For the aforesaid saw blade and the multi-wire cutting apparatus with the same, the conventional methods in the industry are: firstly, grooving the polyurethane cutting guide wheel (for example, the cutting guide wheel is sent to a processing and covering enterprise, and polyurethane materials are coated on the cutting guide wheel and grooving is carried out on the cutting guide wheel, or the grooved polyurethane cutting guide wheel is directly bought from the processing and covering enterprise) so as to form a wire guide groove; installing each grooved polyurethane cutting guide wheel on a cutting frame of cutting equipment; and winding the cutting wires in the corresponding wire grooves of the polyurethane cutting guide wheels in sequence.

In the above-described technology, there may be disadvantages in that: the polyurethane guide cutting wheels are respectively installed on the corresponding cutting frames after the grooving operation, although the distance between the cutting frames is designed and determined in advance, because the polyurethane guide cutting wheels are installed due to human factors and installation modes (for example, screws are adopted for locking and the number of the screws is possibly large) and other factors, on one hand, the verticality (if the polyurethane guide cutting wheels are vertically arranged) or the levelness (if the polyurethane guide cutting wheels are horizontally arranged) of the polyurethane guide cutting wheels are deviated, so that the verticality or the levelness of the wound cutting wires are influenced, on the other hand, the distance between corresponding wire grooves in the adjacent polyurethane guide cutting wheels and the like can also deviate from the preset design, and therefore, the distance between each section of the cutting wires wound on the polyurethane guide cutting wheels is unequal. These all affect the cutting quality of the workpiece, the former affects the finish of the cut surface, and the latter affects the thickness uniformity of each cut piece or each slice after the workpiece is cut. Of course, the grooving operation is entrusted to an external processing and carrying enterprise to complete, and the quality risk of the wire groove in the polyurethane cutting guide wheel is increased.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

In the multi-wire cutting equipment, for the cutting guide wheel, a grooving operation is performed on the polyurethane cutting guide wheel to form a wire guide groove, and then the grooved polyurethane cutting guide wheels are installed on the cutting equipment to enable a cutting wire to be wound in the wire guide groove of the polyurethane cutting guide wheel. In view of this, the present application provides an improved technique for a cutting guide wheel, which performs a slotting operation on a reproduced field after the cutting guide wheel is installed, eliminates interference of external factors such as an installation operation, and ensures that a distance between wire grooves formed on each cutting guide wheel meets a requirement of a preset wire distance, thereby satisfying a cutting requirement of a workpiece.

Referring to fig. 3, a flowchart of a grooving method for a cutting guide wheel according to the present invention is shown. As shown in fig. 3, the grooving method of the cutter guide wheel of the present invention includes: in step S1, the rollers are mounted at intervals. The purpose of step S1 is to: before grooving the cutting guide wheels, each cutting guide wheel needs to be installed to keep the cutting guide wheels stable. Here, the stabilization is embodied in at least two aspects: 1. the setting face of the guide cutter wheel is ensured to be stable, namely, the guide cutter wheel is ensured to be vertically set (vertically stable) or horizontally set (horizontally stable), and the inclination of the setting face of the guide cutter wheel is avoided as much as possible. Of course, the above arrangement is a preferable mode, but it is not intended to mean that the installation surface of the cutter guide wheel can not be installed at all in an inclined manner, but only in an inclined manner, installation is more difficult, and an uncontrollable risk of deviation generated when the cutter guide wheel rotates during slotting operation is increased, so that complexity of slotting operation is increased and operation difficulty required for ensuring slotting quality is increased. 2. The method ensures that the guide rollers are stable relative to the direction of the guide roller shaft and the distance between the guide rollers is stable, namely, the guide rollers are arranged to limit the deviation of the respective guide rollers in the direction of the guide roller shaft, so that one guide roller of two adjacent guide rollers is prevented from slightly approaching or departing relative to the other guide roller, and the distance between the two guide rollers is changed. In practical applications, in step S1, the rollers may be installed at intervals as follows: the cutting guide wheels are arranged on the cutting frames which are arranged at intervals, or the cutting guide wheels are arranged on the mounting points of the cutting guide wheels which are arranged at intervals in one cutting frame.

In step S2, grooving operation is performed on each of the cutter guide wheels. In step S2, the grooving operation is performed on each of the shear rollers in sequence according to the predetermined line pitch, and since each of the shear rollers is installed previously (the subsequent grooving operation is not affected by the operations such as installation of the shear rollers), it can be ensured that the distance between the wire grooves formed by grooving each of the shear rollers in the grooving operation is the predetermined line pitch as long as the travel according to the predetermined line pitch is controlled, and the operation requirements are met.

It should be noted that in step S1, the final shear roller is provided as a non-grooved primary shear roller, unlike the prior art grooved final shear roller.

The invention provides a cutting guide wheel, which comprises: guide pulley body and guide pulley groove coating. The guide wheel body is a metal guide wheel, and in one embodiment, the guide wheel body is an iron core. In order to facilitate installation, the center of the guide wheel body can be provided with a central shaft hole, a transmission shaft can be installed through the central shaft hole, and the transmission shaft is in shaft-driven connection with the guide wheel body (the guide wheel body and the transmission shaft can rotate relatively). The part of the transmission shaft far away from the guide wheel body can be further provided with a mounting structure, the mounting structure can be a mounting screw hole or a mounting through hole, and the mounting screw hole or the mounting through hole can be multiple and evenly distributed. The mounting is done with a drive shaft. And the guide wheel groove coating layer is coated on the periphery of the guide wheel body. In the present embodiment, the sheave groove coating layer is made of urethane rubber or a resin material (ultra high molecular weight polyethylene). In general, in a practical process, a coating layer with a certain thickness and width is formed on a guide wheel body by pressing urethane rubber or resin material (ultra-high molecular weight polyethylene), and the coating layer can form a wire guide groove on the surface through a grooving operation, so that the coating layer is called a guide wheel groove coating layer. In order to facilitate the subsequent grooving operation to form the wire groove, in this embodiment, on one hand, the wheel groove coating has at least one wire groove configuration layer (depending on the thickness of the wheel groove coating and the production process requirements of the multi-wire cutting device), a plurality of wire groove configuration layers are stacked on each other in the thickness dimension, when one wire groove layer reaches the wear loss after being used, the worn wire groove layer is turned off and the grooving operation is performed on the next wire groove configuration layer to form the wire groove, so that the multiple utilization (the more the number of the wire groove layers, the higher the utilization rate) can be realized. On the other hand, each wire groove configuration layer can be used for configuring at least one wire groove (according to the width of the guide wheel groove coating and the production process requirement of the multi-wire cutting equipment), the plurality of wire grooves are arranged at intervals in the width dimension and are mutually parallel, when one wire groove is used to reach the abrasion loss, the cutting wire is switched into other wire grooves from the worn wire groove, and therefore the service cycle can be prolonged (the more the number of the wire grooves is, the higher the utilization rate is).

In step S2, the grooving machine is used to perform the grooving operation on the guide pulleys sequentially according to the predetermined pitch, and in view of this, the present invention further provides a grooving machine dedicated for the grooving operation. Referring to fig. 4 to 7, fig. 4 is a perspective view of a grooving machine for grooving the cutting guide wheel according to the present invention, fig. 5 is a front view of the grooving machine, fig. 6 is a side view of the grooving machine, and fig. 7 is a top view of the grooving machine. It is noted that to more clearly describe the grooving operation of the grooving machine specific to the shear roller, in these figures, the shear roller is also shown. With reference to fig. 4 to 7, the slotter disclosed in the present invention includes: an operator platform 21, a shear shoe mounting structure 23, and a grooving apparatus 25.

The operation platform 21 includes a work table 211 and support legs 213 for supporting the work table 211. In the present embodiment, the work table 211 is a rectangular table. An electrical box 27 may also be provided alongside the operator's platform 21.

Idler mounting structure 23 is used to mount idler 100. As previously mentioned, each cutting guide must be installed and held stationary prior to the grooving operation. Here, the stabilization is embodied in at least two aspects: 1. the stability of the setting surface of the guide cutter wheel is ensured, namely, the guide cutter wheel is arranged vertically (stable in degree) or horizontally (stable in levelness), and the inclination of the setting surface of the guide cutter wheel is avoided as much as possible. Of course, the above-mentioned arrangement is a preferable mode, but not limited to this, and it is not necessarily that the installation surface of the cutter guide wheel is installed obliquely, but it is only that the installation is more difficult in an oblique manner, and the uncontrollable risk of deviation generated when the cutter guide wheel rotates during the grooving operation is increased, which increases the complexity of the grooving operation and increases the operation difficulty of ensuring the grooving quality requirement. 2. The stability of the shear rollers relative to the direction of the idler shaft is ensured by mounting each shear roller to limit the deflection of the respective shear roller in the direction of the idler shaft, preventing one of the adjacent shear rollers from moving slightly closer or further away from the other shear roller, changing the spacing therebetween. In the present disclosure, mounting of idler cutter 100 specifically means mounting each idler cutter 100 in a spaced manner, and the distance between two adjacent idler cutter 100 satisfies a predetermined line distance. The spaced mounting of the guide rollers 100 can be achieved in a variety of ways, and in an alternative implementation, a mounting frame 10 is provided, a plurality of cutting brackets 11 are spaced apart from each other on the mounting frame 10, and in operation, the guide rollers 100 are mounted on the corresponding cutting brackets 11, and the mounting frame 10 is mounted and fixed on the guide roller mounting structure 23 of the grooving machine. Further, idler wheel mounting structure 23 may be provided on a rear side of work surface 211, for example, using a mounting table. For example: in one case, the two mounting bases 23 are provided at opposite ends of the work table 211, and the mounting frame plate 10 is erected on the two mounting bases 23. In another case, the number of the mounting stages 23 may be three or more, a plurality of the mounting stages 23 are uniformly distributed, and the mounting frame plate 10 is erected on each of the mounting stages 23. In order to fix the mounting frame plate 10 to the mounting platform 23, the mounting frame plate 10 may be fixed to the mounting platform 23 by screws, fasteners, clamps, or the like.

The grooving apparatus 25 includes: the slotting cutter, the slotting cutter moving mechanism and the cutting guide wheel transmission device.

The grooving tool 251 may be a turning tool, a milling cutter, or other commonly used cutting tools in the prior art, or a suitable tool may be developed by itself according to the actual groove grooving process of the wire guide groove. To facilitate movement of grooving tool 251 and stability during the grooving operation, grooving tool 251 is mounted on a tool holder 252 and faces cutting guide wheel mounting structure 23. Alternatively, the tool rack 252 may be, for example, a frame structure.

The slotting cutter moving mechanism is used for driving the slotting cutter 251 to move and advance and retreat. Driving the slotting cutter 251 to displace refers to driving the slotting cutter 251 to move along the idler shaft direction of the idler cutter 100 to move to a different idler cutter 100. Driving grooving cutter 251 forward and backward refers to driving the grooving cutter to advance toward or retract away from idler cutter 100 within the setting plane of idler cutter 100. To achieve the displacement and advance and retreat of the slotting cutter 251, in an alternative embodiment, the slotting cutter moving mechanism further comprises a first direction displacement mechanism and a second direction advance and retreat mechanism.

The first direction shift mechanism is used to drive the slotting cutter 251 to move along the first direction to the appointed guide wheel 100, namely, to realize the switching between different guide wheels xx. Specifically, the first direction shift mechanism further includes: a first direction guide 261, a first slider 262, and a first driving source. The first direction guide 261 is laid on the work table 211 along a first direction (for convenience of description, the first direction is denoted as an X-axis in fig. 4). The first slider 262 is adapted to the first direction guide 261 and is disposed at the bottom of a tool base 253. To increase the stability of the displacement of the tool bed 253 in the first direction, the first direction guide rails 261 are paired and correspond to opposite sides of the tool bed 253. The first driving source may include: a first drive motor 263 and a first transmission member. The first transmission member is connected to the first driving motor 263 and the tool bottom platform 253 in a transmission manner, and is controlled by the first driving motor 263 to drive the tool bottom platform 253 to displace along a first direction. Further, the first transmission member may further include a first rotating rod 264 and a first set of blocks 265. The first rotating rod 264 is disposed along a first direction, one end of the first rotating rod 264 is linked to the first driving motor 263 and controlled by the first driving motor 263, and the other end of the first rotating rod 264 is rotatably connected to the bottom or suspension of the work bench 211, optionally, the first rotating rod 264 corresponds to the middle region of the tool bottom platform 253 and is located between the pair of first direction guide rails 261, and the outer surface of the first rotating rod 264 is provided with a thread. The first set block 265 is fixed to the bottom of the tool bottom platform 253 and has an internal thread, and the first set block 265 is sleeved on and screwed to the first rotating rod 264. In the first direction shift mechanism, the length of the first rotating lever 264 determines the moving stroke of the tool base 253 in the first direction. In practical applications, the first rotating rod 264 is matched with the first set of blocks 265 to convert the rotating motion into a linear motion, that is, the first driving motor 263 drives the first rotating rod 264 to rotate, and the first set of blocks 265 and the tool bottom platform 253 are driven to move left and right along the first direction guide 261 (i.e., the first direction) by the rotation of the first rotating rod 264. In this way, the moving distance of the tool base 253 and the grooving tool 251 thereon can be controlled by the first driving motor 263. In addition, in order to connect the first rotating rod 264 and the first sleeve block 265 and generate the effect of relative movement of the first sleeve block 265 along the first rotating rod 264, a shifting tear strip 266 is disposed in the middle region of the tool bottom platform 253 corresponding to the first rotating rod 264, and the shifting tear strip 266 is disposed along the first direction, so that the first sleeve block 265 can move along the first rotating rod 264 relatively. Furthermore, with respect to the first driving source, in an alternative embodiment, the first driving motor 263 may be, for example, a servo motor, and the first rotating member may be, for example, a ball screw, which has the characteristics of high precision, reversibility and high efficiency, so that the precision of the displacement of the tool bottom table 253 and the slotting tool 251 thereon in the first direction is improved by the cooperation of the servo motor and the ball screw.

The second direction advancing and retracting mechanism is used to drive the slotting cutter 251 to advance toward the shear runner 100 or retract away from the shear runner 100 along the second direction. Specifically, the second-direction advancing-retreating mechanism further includes: a second direction guide 271, a second slider 272, and a second driving source. The second direction guide 271 is laid on the tool bed 253 along a second direction (for convenience of description, the second direction is denoted as Y-axis in fig. 4). The second slider 272 is adapted to the second direction guide 271 and disposed at the bottom of a tool rest 252. To increase the stability of the tool rack 252 moving forward and backward along the second direction, a pair of second direction guides 271 is provided, corresponding to the opposite sides of the tool rack 252. The second driving source may include: a second drive motor 273 and a second transmission member. The second transmission member is connected to the second driving motor 273 and the tool rack 252 in a transmission manner, and is controlled by the second driving motor 273 to drive the tool rack 252 to advance and retreat along the second direction. Further, the second transmission component may further include a second rotating rod 274 and a second set of blocks (not shown). The second rotating rod 274 is disposed along the second direction, one end of the second rotating rod 274 is linked to the second driving motor 273 and is controlled by the second driving motor 273, and the other end of the second rotating rod 274 may be suspended, optionally, the second rotating rod 274 corresponds to a middle region of the tool rest 252 and is located between the pair of second direction guide rails 271, and an outer surface of the second rotating rod 274 is provided with a thread. The second sleeve is fixed to the tool holder 252 and has an internal thread, and the second sleeve is sleeved on and screwed to the second rotating rod 274. In the second-direction advancing and retracting mechanism, the length of the second rotating lever 274 determines the advancing and retracting stroke of the tool holder 252 and the grooving tool 251 mounted thereon in the second direction. In practical applications, the second rotating rod 274 and the second set of blocks are matched to convert the rotating motion into a linear motion, that is, the second driving motor 273 drives the second rotating rod 274 to rotate, and the second set of blocks and the tool rack 252 are driven to advance and retreat back and forth along the second direction guide 271 (i.e., the second direction) by the rotation of the second rotating rod 274. In this way, the second driving motor 273 can control the advancing and retreating distance of the tool holder 252 and the slotting tool 251 thereon. In addition, for the second driving source, in an alternative embodiment, the second driving motor 273 may be, for example, a servo motor, and the second rotating member may be, for example, a ball screw, which has the characteristics of high precision, reversibility and high efficiency, so that the precision of advancing and retracting the tool holder 252 and the slotting tool 251 thereon in the second direction is improved through the cooperation of the servo motor and the ball screw.

It should be noted that, in practice, in the process of grooving the cutting guide wheel by using the grooving machine of the present invention, besides the grooving operation by controlling the grooving tool 251, the outer circle grinding or the outer circle turning of the cutting guide wheel before the grooving operation is actually required. Taking cylindrical turning as an example, an outer cylindrical turning tool 254 may optionally be provided, and the outer cylindrical turning tool 254 may be disposed on the tool holder 252. As described above, the slotting cutter moving mechanism includes the first direction shifting mechanism and the second direction advancing and retreating mechanism to respectively drive the slotting cutter 251 to shift along the first direction and advance and retreat along the second direction, so that the external lathe tool 254 can be arranged in parallel with the slotting cutter 251 in the first direction, the slotting cutter moving mechanism can be fully utilized, and no additional new moving mechanism is required. With the aid of the grooving tool moving mechanism, the outer turning tool 254 can also be displaced in the first direction and advanced and retracted in the second direction, so that the outer turning work can be performed for each of the cutter guide wheels 100.

The cutting guide wheel transmission device is used for driving the cutting guide wheel to rotate. In this embodiment, the shear roller drive may include a shear roller drive member and a second direction movement mechanism.

The idler drive assembly further includes: a transmission base 281, a transmission wheel 282, and a transmission motor 283. The transmission base is erected on the second direction moving mechanism and can move back and forth along the second direction under the drive of the second direction moving mechanism. The driving wheel 282 and the driving motor 283 are both arranged on the driving base 281, and the driving motor 283 can drive the driving wheel 282 to drive. In one implementation, the driving wheel 282 has a shaft drivingly connected to the driving motor 283 by a belt.

The second direction movement mechanism is configured to drive the idler drive member in a second direction to contact and drive idler 100. Specifically, the second-direction moving mechanism further includes: a second direction guide 284, a third slider 285, and a third driving source. The second direction guide 284 is laid on the tool base 253 along a second direction (for convenience of description, the second direction is denoted as Y-axis in fig. 4), and the second direction guide 284 of the second direction moving mechanism is laid on the tool base 253 by a guide pillow block 286 in order to avoid interference with the second direction guide 271 of the second direction advancing and retreating mechanism. The third slider 285 is fitted to the second direction guide 284 and is disposed at the bottom of the transmission base 281. To increase the stability of the movement of the transmission base 281 along the second direction, the second direction guiding rails 284 are a pair, respectively corresponding to two opposite sides of the transmission base 281. The third driving source may include: a third drive motor 287 and a third transmission member. The third transmission member is connected to the third driving motor 287 and the transmission base 281 in a transmission manner, and is controlled by the third driving motor 287 to drive the transmission base 281 to move back and forth along the second direction. Further, the third transmission component may further include a third rotating rod (not shown in the drawings) and a third set of blocks (not shown in the drawings). The third rotating shaft is disposed along the second direction, one end of the third rotating shaft is linked to the third driving motor 287 and is controlled by the third driving motor 287, and the other end of the third rotating shaft may be suspended, optionally, the third rotating shaft corresponds to a middle region of the transmission base 281 and is located between the pair of second direction guide rails 284, and an outer surface of the third rotating shaft is provided with a thread. The third sleeve block is fixed on the transmission base 281 and has an internal thread, and the third sleeve block is sleeved on and screwed with the third rotating rod. In the second direction moving mechanism, the length of the third rotating lever determines the moving stroke of the transmission base 281 and the transmission wheel 282 mounted thereon in the second direction. In practical applications, the third rotating rod and the third set of blocks are matched to convert the rotating motion into a linear motion, that is, the third driving motor 287 drives the third rotating rod to rotate, and the third set of blocks and the transmission base 281 are driven to move back and forth along the second direction guiding rail 284 (i.e., the second direction) by the rotation of the third rotating rod. In this way, the third driving motor 287 can control the moving distance of the transmission base 281 and the transmission wheel 282 thereon. In addition, regarding the third driving source, in an alternative embodiment, the third driving motor 287 may be, for example, a servo motor, and the third rotating member may be, for example, a ball screw, which has the features of high precision, reversibility and high efficiency, so that the precision of the movement of the transmission base 281 and the transmission wheel 282 thereon in the second direction is improved by the cooperation of the servo motor and the ball screw. Of course, the second direction moving mechanism is not limited thereto, and the second direction moving mechanism may still be changed in other ways under the condition that the turning amount of the outer circle of the cutting guide wheel is satisfied, for example, in another variation, the third driving source in the second direction mechanism may include an air cylinder with a piston rod, one end of the piston rod is connected to the air cylinder, the other end of the piston rod is connected to the transmission base 281, and the air cylinder may drive the piston rod to move telescopically, so as to drive the transmission base 281 to move back and forth along the second direction.

According to the above description of the structure of the guide bar driving device, in practical application, the second direction moving mechanism is used to drive the guide bar driving member to move back and forth along the second direction, when the driving wheel 282 of the guide bar driving member effectively contacts the guide bar 100, the driving motor 283 drives the driving wheel 282 to rotate, and the guide bar 100 is driven to rotate by the friction between the driving wheel 282 and the guide bar 100. In addition, since the second direction moving mechanism is provided on the tool base 253, the cutter guide wheel transmission device moves left and right in the first direction together with the tool base 253 and the grooving tool 251 thereon.

Since only one grooving operation is performed in the first embodiment, the grooving position of the first shear roller 100 can be the widthwise central position of the first shear roller 100.

During the grooving operation, first idler cutter 100 continues to rotate, and grooving tool 251 continues to advance in the second direction in steps until a predetermined amount of advance is reached. In some embodiments, if the width of the wire groove to be formed is larger (the width of the wire groove is larger than the width of the grooving tool) according to the grooving requirement, the grooving tool 251 can still swing left and right in the first direction by the first direction moving mechanism during the grooving operation, so as to obtain a larger width of the groove.

Fifth embodiment:

fig. 20 is a schematic flow chart of a grooving method for a cutting guide wheel according to a fifth embodiment of the present invention. In this fifth embodiment, the method is used for performing multiple grooving operations on a shear runner, wherein at least one grooving operation is performed on the shear runner during each grooving operation. In the following description, a two-stage grooving operation is taken as an example. Referring to fig. 4 to 7, as shown in fig. 20, the grooving method for the shear roller according to the present invention includes:

in step S61, the rollers are mounted at intervals. In step S61, mounting each of the shear runners in a spaced apart relationship may include: installing the cutting guide wheels 100 on the corresponding cutting brackets 11 respectively, wherein the cutting brackets 11 are arranged on an installation frame plate 10 at intervals, and the distance between every two adjacent cutting guide wheels meets the preset line distance; the mounting frame plate 10 is fixed to a mounting table 23 of the slotter. In the third embodiment, assuming that a plurality of cutting brackets 11 are spaced apart from one mounting frame plate 10, each cutting bracket 11 can be mounted with one cutter guide roller 100.

And step S62, performing outer circle turning on each cutting guide wheel in sequence. By turning the outer circumference of each of the shear runners 100 in step S62, each of the shear runners 100 can achieve desired dimensional and surface flatness requirements (e.g., removing roughness from the surface of the runner' S groove coating). The sequential cylindrical turning of the guide cutters in step S62 can be generally summarized as: moving the cylindrical turning tool to the current cutting guide wheel, and performing cylindrical turning operation on the current cutting guide wheel; moving the cylindrical turning tool to the next adjacent cutting guide wheel according to the preset line distance, and performing cylindrical turning operation on the next cutting guide wheel; and repeating the steps of moving the cylindrical turning tool to the next adjacent cutting guide wheel according to the preset line distance and carrying out cylindrical turning operation on the cylindrical turning tool until the cylindrical turning operation of all the cutting guide wheels is completed. For a detailed process of sequentially turning the outer circle of each guide cutter wheel in step S62, reference may be made to the description of step S33 and the detailed flowchart of fig. 14 in the second embodiment, which are not repeated herein.

Step S63, at least one grooving operation is performed on each guide cutter wheel in sequence. In step S63, if a grooving operation is performed on each guide cutter wheel, refer to step S35 in the second embodiment and the detailed flowchart of step S35 shown in fig. 15; if multiple grooving operations are performed on each of the guide cutters, reference may be made to the descriptions of step S43 to step S46 in the third embodiment. Through the steps S61 to S63, the grooving operation for the first layer and at least one wire guiding groove of the cutting guide wheel can be completed.

In this case, the mounting frame plate 10 and the cutter guide 100 can be detached from the mounting table 23 of the slotter, and the mounting frame plate 10 can be mounted in the multi-wire cutting apparatus to perform the multi-wire cutting work. Specifically, a plurality of installation frame plates are fixedly installed on a base of the multi-wire cutting equipment in a pairwise opposite mode, and the pairwise opposite installation frame plates can be horizontally placed or vertically placed according to the multi-wire cutting requirement. When two opposite installation frame plates are horizontally arranged, the cutting frames on the installation frame plates and the cutting guide wheels on the installation frame plates are in one-to-one correspondence, the cutting lines are sequentially wound in the same wire groove of each cutting guide wheel, and therefore the cutting line segments wound on the cutting guide wheels in one-to-one correspondence are horizontally arranged. When two pairwise opposite installation frame plates are vertically placed, the cutting frames on the installation frame plates and the cutting guide wheels on the installation frame plates are in one-to-one correspondence, the cutting lines are sequentially wound in the same wire groove of each cutting guide wheel, and therefore the cutting line segments wound on the one-to-one correspondence cutting guide wheels are vertically arranged. In this manner, the relative multi-wire cutting operation can be performed using a multi-wire cutting apparatus equipped with grooved cutting rollers.

Furthermore, after a certain usage amount, it is likely that the current wire groove will be worn and the cutting wire needs to be switched to another wire groove, but during switching, the cutting wire wound on each guide cutting wheel is switched from the current wire groove to another wire groove to be switched, so as to ensure that the distance between adjacent cutting wires wound on each guide cutting wheel still meets the preset wire distance.

Further, when all of the wire guide slots become worn, the cutting block must be replaced. The common practice is: the worn out guide rollers are removed from their respective cutting block and new non-grooved guide rollers are mounted on the cutting block for subsequent grooving operations. This general practice exists: the loading and unloading operations are complicated, time-consuming and labor-consuming; the installation of a new shear roller increases the risk of parameter variations (e.g., alignment of the vertical or horizontal placement of the shear roller), etc.

In view of the above, in the grooving method for the cutting guide wheel according to the present invention, the grooving operation for the next layer can be continued on the cutting guide wheel.

And continuing to step 64, and sequentially turning the outer circles of the guide cutting wheels. In practical applications, the mounting frame plates still need to be mounted on the respective mounting tables of the slotter before the step S64 is executed. And S64, performing cylindrical turning on each guide cutting wheel, and performing cylindrical turning on each guide cutting wheel to turn off the wire guide grooves formed in the previous layer of slotting operation of each guide cutting wheel. The sequential cylindrical turning of the guide cutters in step S64 can be generally summarized as: moving the cylindrical turning tool to the current cutting guide wheel, and performing cylindrical turning operation on the current cutting guide wheel; moving the cylindrical turning tool to the next adjacent cutting guide wheel according to the preset line distance, and performing cylindrical turning operation on the next cutting guide wheel; and repeating the steps of moving the cylindrical turning tool to the next adjacent cutting guide wheel according to the preset line distance and carrying out cylindrical turning operation on the cylindrical turning tool until the cylindrical turning operation of all the cutting guide wheels is completed. For a detailed process of sequentially turning the outer circle of each guide cutter wheel in step S64, reference may be made to the description of step S33 and the detailed flowchart of fig. 14 in the second embodiment, which are not repeated herein.

Step S65, at least one grooving operation is performed on each guide cutter wheel in sequence. Here, if a grooving operation is performed on each of the cutter guide wheels, reference may be made to step S35 in the second embodiment and a detailed flowchart of step S35 shown in fig. 15; if multiple grooving operations are performed on each of the guide cutters, reference may be made to the descriptions of step S43 to step S46 in the third embodiment.

Through the steps S64 to S65, the grooving operation for the second layer and at least one wire guiding groove of the cutting roller can be completed. In this way, the cutting wheels can be reloaded on the multi-wire cutting apparatus for continued use (a two-tier grooving process can be seen in fig. 21). The utilization rate of the cutting guide wheel is improved, and the operation and the subsequent adjustment during the middle loading, unloading and replacing are avoided.

The invention discloses a slotting method of guide pulleys, which is characterized in that each guide pulley is installed firstly, and then a slotting machine is utilized to carry out field slotting operation on each guide pulley, thus eliminating the factors of deviation generated in the installation process of the guide pulleys, ensuring that the space between wire grooves formed by slotting each guide pulley can meet the requirement of the preset wire distance as long as the shifting precision of the slotting machine in the slotting operation is controlled, and solving the problem that the space between the wire grooves at the corresponding positions of each guide pulley can not meet the requirement of the preset wire distance as the guide pulleys are installed in the prior art, wherein the wire grooves are formed by slotting each guide pulley firstly and then are installed one by one and are adjusted.

The invention effectively overcomes various defects in the prior art and has high industrial utilization value.

Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
