Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, in particular to a cutting equipment for processing guide rollers. Background Art

[0002] In the field of modern industrial production, guide rollers are widely used in production lines of many industries such as papermaking, printing, textiles, metallurgy and plastic processing. They are one of the key components to ensure stable operation of the production line and product quality. The processing quality of guide rollers, especially the cutting accuracy, has a vital impact on their performance and life. With the development of industrial production towards high precision and high efficiency, higher requirements are placed on the cutting accuracy and production efficiency of guide rollers. At present, in the cutting process of guide rollers, traditional cutting equipment mostly adopts the method of rotary cutting disc. However, the existing rotary cutting equipment has the following technical problems when used:

[0003] Existing cutting equipment mostly uses a single rotation motion, but cannot improve the cutting efficiency and cutting strength of the guide roller through the synchronous multi-effect and multi-dimensional motion of the cutter head;

[0004] The existing cutting equipment has low chip removal efficiency due to the limitation of single rotating structure;

[0005] 3. Traditional equipment mostly uses a single constant load cutting mode, and the tool is continuously subjected to peak cutting force, resulting in accelerated tooth wear;

[0006] Based on this, the present invention provides a cutting device for guide roller processing to solve the problems raised in the above background technology. Summary of the Invention

[0007] The present invention addresses the technical problems existing in the prior art. The cutting equipment for guide roller processing of the present invention solves the problems of difficult control of cutting pressure and position of existing equipment, low transmission accuracy, large gear wear, difficulty in heating and chip removal of the cutter disc, and inconvenient monitoring through the coordinated vibration of the pressure frame and the grinding frame, unique design of the cutter disc, optimization of the transmission structure, and cooling and monitoring system. It improves cutting efficiency and quality, reduces maintenance costs, and extends the life of equipment and tools.

[0008] The technical solution of the present invention to solve the above technical problems is as follows: a cutting device for guide roller processing, comprising a pedestal, a lifting module and a motor, and also comprising a cutting frame, a lifting frame is installed on the lifting module for transmission, a group of pressure sensors are installed between the lifting frame and the cutting frame, a pressing frame that can be reciprocated up and down is installed on the cutting frame, a grinding frame that can be reciprocated back and forth is installed on the pressing frame for transmission, the pressing frame and the grinding frame are both driven by the motor to move, the reciprocating stroke and reciprocating frequency of the pressing frame and the grinding frame change alternately in two modes, a knife shaft driven by the motor is rotatably installed on the grinding frame, a knife disc is installed on the knife shaft, and three cutting segments and There are three chip removal segments, the center angle corresponding to the cutting segment is 90°, and the center angle corresponding to the chip removal segment is 30°. A tool holder is installed on each cutting segment, and multiple groups of teeth are installed on the tool holder along the rotation direction of the cutter disc. The height of each group of teeth decreases by 10% to 15% relative to the previous group along the cutting direction, and the pitch of each group of teeth decreases by 5% to 10% relative to the previous group. The reciprocating motion of the pressure frame and the grinding frame has a phase difference of 90°, forming a coordinated vibration mode of staggered reciprocating motion. High-pressure air holes are evenly distributed on the chip removal segments, and the angle between the axis of the high-pressure air holes and the horizontal plane is 45°. Counterweight blocks are threadedly installed on the cutter disc and corresponding to each chip removal segment.

[0009] The beneficial effects of the present invention are:

[0010] 1. The present invention improves the cutting efficiency and cutting strength of the guide roller through the synchronous multi-effect and multi-dimensional movement of the cutter disc. The up and down and front and back reciprocating motions of the pressure frame and the grinding frame, and the stroke and frequency change cyclically, also have a 90° phase difference, forming a coordinated vibration mode of staggered reciprocating motion. This mode causes the cutting force to fluctuate periodically, avoiding tool fatigue wear under a single constant load. When the stroke ratio is 1.5:1, the force distribution of the upper and lower pressure frames and the front and back grinding forms a dynamic gradient, which can reduce the peak cutting force. It is especially suitable for layered cutting of high-hardness guide roller materials. The 90° phase difference causes the movements of the pressure frame and the grinding frame to be staggered and superimposed, forming a "vibration cutting" effect. The combined force of the two can disperse the stress of the material in the cutting area, reduce the resistance to plastic deformation, and reduce cutting energy consumption.

[0011] 2. The cutter disc of the present invention is provided with three cutting sections and three chip removal sections at intervals, forming a "cutting, chip removal" periodic cycle, ensuring that the cutter disc completes three cutting and chip removal actions for every rotation, avoiding the accumulation of chips in the cutting area, reducing the secondary wear of the tool by chips, and preventing chip blockage from affecting the subsequent cutting accuracy. The 30° chip removal section angle design takes into account the chip removal time and the compactness of the cutter disc structure, achieving a balance between the chip removal time and the compactness of the cutter disc structure, and improving the overall processing smoothness. The chip removal section is evenly distributed with high-pressure air holes, and its axis forms an angle of 45° with the horizontal plane, so that the airflow has horizontal thrust and vertical lifting force along the direction of rotation of the cutter disc, forming a synergistic chip removal effect of "airflow plus centrifugal force", reducing the energy consumption of the high-pressure air source, and is particularly suitable for removing powdered or small-particle chips.

[0012] 3. In the present invention, the height of each set of teeth decreases by 10% along the rotation direction of the cutter disc, forming a "step cutting" mode, which decomposes the high resistance of traditional single-knife full cutting into multiple layers of small resistance cutting, thereby reducing the peak cutting force. It is especially suitable for processing high hardness or toughness materials. The tooth pitch decreases by 5% gradient, and the height gradient is combined to make the cutting trajectory gradually densified, reducing material tearing and avoiding chip jamming due to excessive tooth pitch, further optimizing the chip removal effect. The gradient design reduces the instantaneous impact load of a single set of tools and reduces the risk of tool chipping. At the same time, multi-layer cutting disperses the cutting heat, avoids tool annealing caused by local overheating, and the measured tool life can be extended.

[0013] 4. The present invention uses a pressure sensor to monitor the pressure changes during the cutting process in real time. The microcontroller accurately controls the equipment according to the data of the encoder, the three-axis acceleration sensor and the pressure sensor to ensure the stability and accuracy of the cutting process. This structural design solves the problem that the existing guide roller cutting equipment is difficult to accurately control the cutting pressure and position during the cutting process. Moreover, through the setting of the pressure sensor, it is possible to monitor in real time the pressure between the cutter disc and the guide roller to be cut during the cutting operation, thereby adjusting the height of the lifting frame in real time and avoiding overload when the cutter disc is working.

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] The present invention provides the following preferred embodiments

[0037] like Figure 1-10 As shown, a cutting device for guide roller processing includes a base 1, a lifting module 2 and a motor 3, and also includes a cutting frame 4. A lifting frame 5 is installed on the lifting module 2, and a group of pressure sensors 6 are installed between the lifting frame 5 and the cutting frame 4;

[0038] A column 14 is mounted on the pedestal 1, a lifting module 2 is mounted on the column 14, a microcontroller 15 is mounted on the column 14, a lifting frame 5 is slidably connected to the column 14, and a motor 3 is fixedly mounted on the cutting frame 4;

[0039] A pressing frame 7 is mounted on the cutting frame 4 and can be reciprocated up and down. A grinding frame 8 is mounted on the pressing frame 7 and can be reciprocated back and forth. Both the pressing frame 7 and the grinding frame 8 are driven by the motor 3. The reciprocating stroke and reciprocating frequency of the pressing frame 7 and the grinding frame 8 are alternately changed in two modes.

[0040] A triaxial acceleration sensor 16 is mounted on the grinding frame 8, and an encoder is integrated into the motor 3. The data terminals of the encoder, triaxial acceleration sensor 16, and pressure sensor 6 are all connected to the microcontroller 15. A knife groove 17 is provided on the base 1 at a position corresponding to the position directly below the knife disc 10.

[0041] The microcontroller 15, encoder, triaxial acceleration sensor 16 and pressure sensor 6 can all be customized or selected according to actual needs;

[0042] It also includes a clamp 44 mounted on the base 1, and the clamp 44 clamps the guide roller to be cut;

[0043] The pedestal 1 provides a stable support base for the entire device. The lifting module 2 installed on the column 14 can realize the lifting movement of the lifting frame 5, thereby driving the cutting frame 4 to move closer to or away from the guide roller to be cut. The installation of the pressure sensor 6 can monitor the pressure changes during the cutting process in real time. The microcontroller 15 accurately controls the device based on the data of the encoder, the three-axis acceleration sensor 16 and the pressure sensor 6 to ensure the stability and accuracy of the cutting process. This structural design solves the problem that the existing guide roller cutting equipment has difficulty in accurately controlling the cutting pressure and position during the cutting process. In addition, through the provision of the pressure sensor 6, the pressure between the cutter head 10 and the guide roller to be cut can be monitored in real time during the cutting operation, thereby adjusting the height of the lifting frame 5 in real time and avoiding overload of the cutter head 10 during operation.

[0044] The microcontroller 15 has a built-in PID control algorithm, which adjusts the lifting speed of the lifting module 2 and the speed of the motor 3 in real time according to the feedback signals from the pressure sensor 6, the encoder and the three-axis acceleration sensor 16;

[0045] A knife shaft 9 driven to rotate by a motor 3 is rotatably mounted on the grinding frame 8;

[0046] The maximum displacement stroke of the pressing frame 7 when driven by the first small-angle tooth segment 20 is 10 mm, and the maximum displacement stroke when driven by the first large-angle tooth segment 21 is 15 mm;

[0047] The maximum displacement stroke of the grinding frame 8 driven under the second small-angle tooth segment 31 is 7 mm, and the maximum displacement stroke driven under the second large-angle tooth segment 32 is 10 mm;

[0048] The frequency of the pressing frame 7 when driving the first small-angle tooth segment 20 and the frequency of the grinding frame 8 when driving the second small-angle tooth segment 31 are both 11 Hz;

[0049] The reciprocating frequency of the pressing frame 7 when the first high-angle tooth segment 21 is driven and the reciprocating frequency of the grinding frame 8 when the second high-angle tooth segment 32 is driven are both 8HZ;

[0050] The reciprocating motion of the pressing frame 7 and the grinding frame 8 has a phase difference of 90°, forming a coordinated vibration mode of staggered reciprocating motion;

[0051] The cyclic changes in reciprocating stroke and frequency make the cutting force fluctuate periodically, thus avoiding tool fatigue wear under a single constant load;

[0052] The up and down movement of the pressing frame 7 and the force distribution of the front and back grinding of the grinding frame 8 form a dynamic gradient, which can reduce the peak cutting force and is particularly suitable for layered cutting of high-hardness guide roller materials.

[0053] The 90° phase difference causes the movements of the pressing frame 7 and the grinding frame 8 to overlap at different times, creating a "vibration cutting" effect. When the pressing frame 7 is pressed down to its maximum stroke, the grinding frame 8 is in the acceleration stage of its forward and backward movement. The combined force of the two can disperse the stress of the material in the cutting area, reduce the resistance to plastic deformation, and thus reduce the cutting resistance.

[0054] The chip removal section 11 with a 30° center angle on the cutter head 10 cooperates with the vibration mode. When the pressure frame 7 and the grinding frame 8 are in the non-cutting stroke, the high-pressure air hole 13 cooperates with the negative pressure effect generated by the vibration to improve the chip removal efficiency. For example, when cutting stainless steel guide rollers, traditional equipment is prone to chip accumulation, while this design allows the chips to be quickly discharged from the tool groove 17 along the 45° airflow direction.

[0055] The reciprocating vibration drives the cutter head 10 to move in multiple dimensions relative to the cooling nozzle 40, and the air flow disturbance generated by the movement of the grinding frame 8 allows the coolant to evenly cover the cutting section of the cutter head 10, thereby controlling the tool temperature below 120°C and effectively extending the service life of the cutter teeth 12;

[0056] The coordinated vibration generates high-frequency micro-vibration on the cutting surface, which can reduce the roughness of the cutting surface of the guide roller and reduce the subsequent grinding process;

[0057] A counterweight 46 is threadedly mounted on the cutter head 10 at a position corresponding to each chip removal segment 11;

[0058] When the cutter disc 10 rotates to perform cutting operations, the forces applied to various parts of the cutter disc 10 are uneven;

[0059] The cutting section will generate greater resistance when cutting, while the chip removal section 11 is relatively less stressed. This uneven stress situation can easily cause the cutter head 10 to be unbalanced during rotation, thereby causing vibration. The vibration will not only affect the cutting accuracy, but also damage the cutter head 10, the cutter shaft 9 and the entire cutting equipment, shortening the service life of the equipment. By threading a counterweight block 46 on each chip removal section 11 and customizing the counterweight weight according to the actual dynamic balancing requirements, the weight distribution of the cutter head 10 can be effectively balanced, so that the stress on each part of the cutter head 10 is more even when rotating.

[0060] The weight of the counterweight 46 is determined by a dynamic balance test;

[0061] A bottom shaft 18 is rotatably mounted on the cutting frame 4, and the output shaft end of the motor 3 is transmission-connected to the bottom shaft 18 through a first synchronous toothed belt. Two vertical gear discs 19 are mounted on the bottom shaft 18, and the vertical gear discs 19 are respectively provided with a first small-angle tooth segment 20 and a first large-angle tooth segment 21. Two first toothless sections 22 are provided on the vertical gear disc 19 and corresponding to the position between the first small-angle tooth segment 20 and the first large-angle tooth segment 21. Two vertically arranged vertical racks 23 are mounted on the pressing frame 7, and the vertical racks 23 are adaptively engaged with the first small-angle tooth segment 20 and the first large-angle tooth segment 21. Two T-shaped guide rods 24 are mounted on the pressing frame 7, and the two T-shaped guide rods 24 are both slidably connected to the cutting frame 4. A first return spring 25 is sleeved on the two T-shaped guide rods 24 and corresponding to the position between the pressing frame 7 and the cutting frame 4.

[0062] It also includes a movable shaft 26 rotatably connected to the press frame 7, a top shaft 27 and a fixed shaft 28 rotatably connected to the cutting frame 4, and first bevel gears are installed on the fixed shaft 28 and the bottom shaft 18, and the two first bevel gears are orthogonally meshed;

[0063] A first coupling groove is fixedly provided inside the fixed shaft 28 and has an opening at the top and is slidably connected to the movable shaft 26;

[0064] The movable shaft 26 and the top shaft 27 are both equipped with second bevel gears, and the two second bevel gears are orthogonally meshed. The grinding frame 8 is slidably connected to the pressing frame 7, and the pressing frame 7 is fixed with a guide groove slidably connected to the grinding frame 8.

[0065] A translation tooth plate 29 is mounted on the grinding frame 8, and a flat tooth disc 30 is mounted on the movable shaft 26. The flat tooth disc 30 is provided with a second small-angle tooth segment 31 and a second large-angle tooth segment 32. Two second toothless sections 33 are provided on the flat tooth disc 30 at positions corresponding to the positions between the second small-angle tooth segment 31 and the second large-angle tooth segment 32. The translation tooth plate 29 is adapted to mesh with the second small-angle tooth segment 31 and the second large-angle tooth segment 32.

[0066] A set of second return springs 34 are mounted on the side of the grinding frame 8 and are limited by the pressure frame 7. A driving wheel shaft 35 and a driven wheel shaft 36 are rotatably mounted on the grinding frame 8. A second coupling groove with one end open and slidably connected to the driving wheel shaft 35 is fixedly formed on the top shaft 27.

[0067] The cross sections of the first coupling groove, the second coupling groove, the movable shaft 26 and the driving wheel shaft 35 are all regular polygons;

[0068] A second synchronous toothed belt is connected between the driving wheel shaft 35 and the driven wheel shaft 36. A third bevel gear is installed on both the driven wheel shaft 36 and the cutter shaft 9. The two third bevel gears are orthogonally meshed.

[0069] The vertical gear disc 19 and the flat gear disc 30 have the same pitch circle diameter and the same rotational speed. The first small-angle tooth segment 20 and the second small-angle tooth segment 31 are circumferentially offset by 90°, and the first large-angle tooth segment 21 and the second large-angle tooth segment 32 are circumferentially offset by 90°.

[0070] The center angles of the effective meshing areas on the first low-angle tooth segment 20 and the second low-angle tooth segment 31 are both 30°, the center angle of the effective meshing area on the first high-angle tooth segment 21 is 60°, and the center angle of the effective meshing area on the second high-angle tooth segment 32 is 40°. The center angles of the two first toothless sections 22 on the vertical gear disc 19 are both 142.5°, and the center angles of the two second toothless sections 33 on the flat gear disc 30 are both 150°.

[0071] The motor 3 drives the bottom shaft 18 to rotate through the first synchronous toothed belt. The vertical gear plate 19 on the bottom shaft 18 engages with the vertical rack 23 on the press frame 7 to realize the up and down reciprocating motion of the press frame 7. At the same time, the bottom shaft 18 drives the fixed shaft 28 to rotate through the first bevel gear. The fixed shaft 28 is connected to the movable shaft 26 through the first coupling groove. The flat gear plate 30 on the movable shaft 26 engages with the translational gear plate 29 on the grinding frame 8 to realize the forward and backward reciprocating motion of the grinding frame 8.

[0072] This transmission structure design makes the movements of the press frame 7 and the grinding frame 8 interrelated and independent of each other. By reasonably setting the parameters of the vertical gear plate 19 and the flat gear plate 30, the movement stroke and frequency of the press frame 7 and the grinding frame 8 can be accurately controlled. The cross-sections of the first coupling groove, the second coupling groove, the movable shaft 26 and the driving wheel shaft 35 are all regular polygons, ensuring the stability and reliability of the transmission. This transmission structure solves the problems of the existing guide roller cutting equipment with complex transmission methods and difficulty in ensuring accuracy. Compared with the existing technology, it improves the accuracy and reliability of the transmission and reduces the maintenance cost of the equipment.

[0073] The first small-angle tooth segment 20, the first large-angle tooth segment 21, the second small-angle tooth segment 31, the second large-angle tooth segment 32, the vertical tooth disc 19 and the flat tooth disc 30 are all provided with a rubber buffer coating, which is made of nitrile rubber and has a thickness of 2.5 mm.

[0074] During the transmission process, the rubber buffer coating can effectively buffer the impact force between gears, reducing gear wear and noise. Nitrile rubber has good wear resistance and oil resistance, and can maintain stable performance during long-term use. This solves the problem of severe gear wear and high noise during the transmission process of existing guide roller cutting equipment. Compared with the existing technology, it extends the service life of the equipment and improves the operating stability of the equipment.

[0075] A cutter disc 10 is mounted on the cutter shaft 9. The cutter disc 10 is provided with three cutting segments and three chip removal segments 11 at intervals. The center angles of the cutting segments are 90°, and the center angles of the chip removal segments 11 are 30°.

[0076] The cutter head 10 is made of high-strength alloy steel;

[0077] Each cutting section is equipped with a tool holder 45. A plurality of groups of cutter teeth 12 are mounted on the tool holder 45 along the rotation direction of the cutter disc 10. The height of each group of cutter teeth 12 decreases gradually by 10% relative to the previous group of cutter teeth 12 along the cutting direction. The pitch of each group of cutter teeth 12 decreases gradually by 5% relative to the previous group of cutter teeth 12.

[0078] High-pressure air holes 13 are evenly distributed on the chip removal section 11 , and the angle between the axis of the high-pressure air holes 13 and the horizontal plane is 45°.

[0079] The cutting section and the chip removal section 11 are arranged at intervals to form a "cutting and chip removal" cycle, ensuring that the cutter head 10 completes three cutting and chip removal actions per rotation. This design avoids the accumulation of chips in the cutting area, reduces the secondary wear of the chips on the tool, and prevents chip blockage that affects the subsequent cutting accuracy. The 30° angle design of the chip removal section 11 takes into account both the chip removal time and the compactness of the cutter head 10 structure.

[0080] If the angle is too small, the chip removal will be insufficient. If it is too large, the cutting section ratio will be compressed, which will reduce the processing efficiency.

[0081] The 30° setting strikes a balance between the two, improving overall processing smoothness. The three cutting segments are evenly distributed, making the force distribution of the cutter disc 10 more uniform when rotating, reducing vibration caused by eccentric loads, extending the life of the cutter shaft 9 bearing, and reducing noise pollution during the processing.

[0082] Along the rotation direction of the cutter head 10, the height of each set of teeth 12 decreases by 10% gradient, forming a "step cutting" mode;

[0083] The first set of teeth 12 cuts into the surface layer of the material first, and the subsequent teeth 12 cut in sequence, breaking down the high resistance of traditional single-knife full cutting into multiple layers of low-resistance cutting, thereby reducing the peak cutting force. This is particularly suitable for processing high-hardness or toughness materials.

[0084] The tooth pitch decreases by 5% in a gradient, and combined with the height gradient, the cutting path becomes gradually denser. This not only reduces material tearing, but also prevents chips from getting stuck due to excessive tooth pitch, further optimizing chip evacuation. The gradient design reduces the instantaneous impact load of a single set of tools and reduces the risk of tool edge breakage.

[0085] At the same time, multi-layer cutting disperses cutting heat, avoids tool annealing caused by local overheating, and the measured tool life can be extended. The axis of the high-pressure air hole 13 is at a 45° angle to the horizontal plane, so that the airflow has both horizontal thrust and vertical lifting force along the rotation direction of the cutter head 10. The horizontal component pushes the chips out along the tangential direction of the cutter head 10 to prevent the chips from flowing back to the cutting area, and the vertical component lifts the chips away from the workpiece surface to prevent the chips from accumulating in the cutting seam. It is especially suitable for removing powdery or small-particle chips.

[0086] The 45° angle design ensures that the direction of the combined force of the airflow impacting the chips is consistent with the direction of the centrifugal force of the cutter head 10, forming a synergistic chip removal effect of "airflow plus centrifugal force" and reducing the energy consumption of the high-pressure air source;

[0087] It also includes a protective shell 37 installed on the cutting frame 4 and a liquid storage tank 38 installed on the lifting frame 5. A corrugated cover 39 is installed between the protective shell 37 and the grinding frame 8. The top of the protective shell 37 is connected to the cooling nozzle 40. A pump body is installed on the liquid storage tank 38. The other end of the pump body is fixedly connected to the cooling nozzle 40 through a pipe. A high-pressure air pump 41 is installed on the side of the protective shell 37. A cavity is opened in the cutter disc 10. The tail end of the high-pressure air hole 13 is connected to the cavity. The air outlet port of the high-pressure air pump 41 is connected to a flexible connecting pipe. The other end of the flexible connecting pipe is rotatably connected to the cavity. A visual acquisition probe 42 and an infrared temperature measurement probe 43 arranged facing the cutter disc 10 are installed on the protective shell 37. The data ends of the visual acquisition probe 42 and the infrared temperature measurement probe 43 are both connected to the data of the microcontroller 15.

[0088] The pump body on the liquid storage tank 38 transports the coolant to the cooling nozzle 40 through a pipeline. The coolant is sprayed on the cutter head 10, which can effectively reduce the temperature of the cutter head 10 during the cutting process and extend the service life of the cutter head 10. The high-pressure air pump 41 installed on the side of the protective shell 37 provides high-pressure air for chip removal. The visual acquisition probe 42 and the infrared temperature measurement probe 43 respectively monitor the cutting condition and temperature of the cutter head 10 in real time and transmit the data to the microcontroller 15.

[0089] The microcontroller 15 adjusts cutting parameters based on this data, including the flow rate of the coolant and the air pressure of the high-pressure air pump 41. This cooling and monitoring system solves the problems of existing guide roller cutting equipment during the cutting process, such as the overheating of the cutter head 10, delayed chip removal, and difficulty in real-time monitoring of the cutting process. Compared with the existing technology, this system improves the reliability and stability of the equipment and ensures cutting quality. In addition, the provision of the visual acquisition probe 42 allows for rapid visual inspection of the wear of the blade teeth 12 after the cutter head 10 has completed cutting.

[0090] The specific method of use of the present invention is as follows:

[0091] The guide roller cutting equipment mainly consists of a base 1, a lifting module 2, a motor 3, and a cutting frame 4. Each system works closely together to complete the guide roller cutting task. The base 1 provides stable support. The lifting module 2 on the column 14 drives the lifting frame 5 and the cutting frame 4 to move toward or away from the guide roller to be cut. The pressure sensor 6 monitors the cutting pressure in real time. The microcontroller 15 accurately controls the equipment based on the data from the encoder, the three-axis acceleration sensor 16, and the pressure sensor 6 to ensure cutting stability and accuracy and avoid overloading the cutter head 10.

[0092] The pressing frame 7 and the grinding frame 8 perform reciprocating motions up and down and back and forth, respectively. Their stroke and frequency change cyclically, and there is a 90° phase difference between the two, forming a coordinated vibration mode. This mode causes the cutting force to fluctuate periodically, reducing tool fatigue wear and lowering the peak cutting force. It is suitable for layered cutting of high-hardness guide roller materials. At the same time, it can also reduce cutting energy consumption, improve chip removal efficiency, evenly cover the coolant, and reduce the roughness of the cut surface.

[0093] The motor 3 drives the bottom shaft 18 to rotate through the first synchronous toothed belt. The vertical gear plate 19 on the bottom shaft 18 engages with the vertical rack 23 on the press frame 7 to realize the up and down movement of the press frame 7. The bottom shaft 18 drives the fixed shaft 28 and the movable shaft 26 through the bevel gear, so that the flat gear plate 30 on the movable shaft 26 engages with the translational gear plate 29 on the grinding frame 8 to realize the forward and backward movement of the grinding frame 8. By reasonably setting the gear plate parameters, the transmission accuracy and reliability are guaranteed, and the maintenance cost is reduced. The rubber buffer coating reduces gear wear and noise, thereby extending the service life of the equipment.

[0094] The cutting section and chip removal section 11 on the cutter head 10 are spaced apart. The stepped teeth 12 of the cutting section reduce the peak cutting force, optimize chip removal, and extend tool life. The high-pressure air holes 13 of the chip removal section 11 are set at a 45° angle, using airflow and centrifugal force to coordinate chip removal and reduce energy consumption. The pump body of the liquid storage tank 38 transports coolant to the cooling nozzle 40 to reduce the temperature of the cutter head 10. The high-pressure air pump 41 provides gas for chip removal. The visual acquisition probe 42 and the infrared temperature measurement probe 43 monitor the condition of the cutter head 10 in real time. The microcontroller 15 adjusts the cutting parameters based on the monitoring data.

[0095] This integrated collaborative system solves the problems of existing guide roller cutting equipment, such as difficulty in accurately controlling cutting pressure and position during the cutting process, complex transmission methods that are difficult to ensure accuracy, severe gear wear and high noise, excessive temperature of the cutter head 10 and untimely chip removal, and difficulty in real-time monitoring of the cutting status. It improves cutting efficiency and quality, reduces equipment maintenance costs, and extends equipment service life.

[0096] The structural parameter innovation in this application focuses on the optimization of the mechanical structure relative to existing equipment, achieving functional breakthroughs based on mechanical principles without relying on new material research and development. The coordinated adjustment of these geometric parameters, motion parameters and transmission layout are all optimized for the shape, position and motion trajectory of mechanical parts. It can be achieved by using conventional industrial materials such as high-strength alloy steel and nitrile rubber. The function is realized by relying on the coordination of structural parameters rather than material properties. The existing material system can meet the needs, and there is no need to verify the performance or processability of new materials, avoiding the risks of material research and development. It can be quickly verified through mechanical design simulation and physical prototype testing, and its strong compatibility facilitates industrial promotion.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
