Description

Technical Field

[0001] This invention relates to the field of roller turning technology, and in particular to a machining process for the roller surface of a high wear-resistant straightener. Background Technology

[0002] A straightening machine is a device used to straighten metal profiles, bars, tubes, wires, etc. The straightening machine uses rollers to compress the bars or other materials, changing their straightness. During the manufacturing process of the straightening machine rollers, they need to be machined.

[0003] In existing roller turning processes, the roller is typically clamped in a machine tool, which drives the roller to rotate. The cutting tool within the machine tool moves radially along the roller to perform the turning. Because the roller surface is uneven, the surface roughness cannot be clearly determined during machining. The cutting depth must be set based on experience, requiring multiple turning operations. This limits the flexibility in adjusting the cutting depth during roller surface machining, reducing machining efficiency. Furthermore, the flatness of the roller surface cannot be automatically checked after machining, making it difficult to determine if the machining accuracy meets requirements. Operators must manually inspect the surface using inspection tools, which also reduces machining efficiency.

[0004] Therefore, the existing roller turning process has the problems of not being able to flexibly adjust the turning depth and not being able to automatically detect the flatness of the roller surface. To address this, we propose a high wear-resistant straightener roller surface processing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a high wear-resistant straightener roller surface processing technology, which can effectively solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a machining process for the roller surface of a high wear-resistant straightening machine. The process utilizes a turning machine, which includes a frame, a positioning assembly, a comprehensive processing assembly, a detection assembly, and a turning assembly. The specific steps of the process are as follows:

[0008] S1. Use positioning components to hold the roller body in place;

[0009] S2. Use a comprehensive processing unit to remove dust and impurities from the roller surface;

[0010] S3. Use a detection component to detect the flatness of the roller surface to determine the cutting depth of the turning component; the frame is provided with a guide ring, and multiple detection components are set inside the guide ring. The detection component includes a fixed seat, a detection shaft elastically connected to one end of the fixed seat, a ball rolled on one end of the detection shaft, and a displacement sensor set on the other end of the fixed seat. The detection end of the displacement sensor abuts against the other end of the detection shaft. When in use, the ball is made to abut against the roller surface, so that the guide ring drives the detection component to move radially along the roller body, and at the same time, the positioning component drives the roller body to rotate. The displacement sensor measures the maximum relative displacement value.

[0011] S4. Use the integrated processing component to spray and cool the roller surface, and use the turning component to cut the roller body; the turning component includes a front cutter and a rear cutter. According to the maximum relative displacement value measured in S3, make the cutting depth of the front cutter greater than half of the maximum relative displacement value, and make the cutting depth of the rear cutter greater than the maximum relative displacement value.

[0012] S5. Check if the processing meets the target requirements; first use the integrated processing component to remove impurities and water stains from the roller surface, then repeat S3 to measure the flatness of the roller surface. If the flatness is within the required range, the processing is complete; otherwise, repeat S4 and S5 until the processing is complete.

[0013] Preferably, the positioning component includes a chuck movably disposed on one side of the frame, a movable frame movably disposed above the other end of the frame, and a pin movably disposed above the side of the movable frame. A power component for driving the chuck to rotate is provided inside the frame.

[0014] In S1, the chuck clamps one end of the roller of the straightener, and the moving frame drives the ejector pin to press against the other end of the ejector pin, so that the roller is clamped on the frame.

[0015] Preferably, the integrated processing component includes a blower, an atomizer, a ring tube, and air nozzles. The blower and atomizer are fixedly mounted above the platform in the middle of the frame. The air outlet of the blower and the air inlet of the atomizer are connected through an air guide pipe. The air outlet of the atomizer and the air inlet of the ring tube are connected through a flexible pipe. Multiple air nozzles are fixedly mounted on the inner side of the ring tube. The multiple air nozzles are evenly spaced on the inner side of the ring tube. The ejector pin is positioned in the middle of the inner side of the ring tube. The ring tube is fixedly mounted on one side of the guide ring.

[0016] In S2, the blower and atomizer are started, and the power unit drives the chuck to rotate, which drives the roller to rotate synchronously. The guide ring drives the ring tube to move radially along the roller, from one end of the roller to the other. During this process, the blower introduces outside air into the atomizer, and the water mist generated by the atomizer is introduced into the ring tube through the flexible tube to form a humid airflow. The humid airflow is sprayed out through multiple air nozzles to perform a dust-suppressing and comprehensive cleaning of the roller surface until the dust and impurities on the roller surface are cleaned.

[0017] Preferably, the detection assembly further includes an adsorption plate fixedly disposed on the side of the detection shaft, a spring sleeved on the side of the detection shaft, an iron core tube sleeved on the side of the detection shaft, and a coil. The coil is sleeved on the side of the iron core tube. The fixed base has a partition plate inside that separates the fixed base into two chambers. The adsorption plate and spring are located in one chamber, and the iron core tube and coil are located in the other chamber. The displacement sensor is fixedly disposed at the end of the fixed base. The detection end of the displacement sensor passes through the fixed base and the iron core tube and extends into the end of the detection shaft. One end of the spring abuts against the adsorption plate, and the other end of the spring abuts against the partition plate. When the coil is energized, it generates a magnetic attraction to the adsorption plate.

[0018] In S2, before the guide ring moves onto the roller, the coil is energized, and the coil generates a magnetic force to attract the adsorption plate, causing the adsorption plate to pull the detection shaft and the ball. Then, the guide ring is placed on the roller. Next, the current to the coil is turned off, and the spring pushes the adsorption plate, causing the detection shaft and the ball to move toward the roller, so that the ball comes into contact with the surface of the roller.

[0019] Preferably, a guide shaft and a lead screw are fixedly provided on one side of the frame, a movable seat is sleeved on the side of the guide shaft, the lead screw drives the movable seat to move radially along the roller body, the guide ring is fixedly provided on one side of the movable seat, and the lead screw drives the guide ring and the ring tube by moving the movable seat.

[0020] Preferably, a heating plate is fixedly installed at the air inlet of the blower. In S2, after the humid airflow removes dust and impurities from the roller surface, the ball continues to press against the roller surface, the guide ring stops moving, and the atomizer is turned off. Then, the heating plate is activated, and the heating plate heats the air at the air inlet of the blower, allowing the hot air to enter the ring pipe. The hot air is sprayed out through the air nozzle and heats the detection shaft and ball located inside the guide ring, causing the ball to roll at the end of the detection shaft. After the ball is heated, it heats the inner groove where the ball is installed at the end of the detection shaft. The moisture on the surface of the inner groove and the ball dries the inner groove and the ball. After drying, the coil is energized, causing the adsorption plate to be magnetically attracted and pull the detection shaft and ball away from the roller surface.

[0021] Preferably, in S4, before cutting, both the guide ring and the turning assembly move to one end of the roller body. The guide ring is in front of the moving direction of the turning assembly. The comprehensive processing assembly sprays humid airflow onto the roller surface again. When the front and rear cutters cut the roller body, the guide ring, the front cutter, and the rear cutter move synchronously. The ring tube and the guide ring prevent the humid airflow from spreading. The humid airflow cools the roller surface during the cutting process. The airflow also generates a thrust on the cut chips, causing the chips to slide off the roller surface.

[0022] Preferably, the turning assembly further includes a radial moving platform fixedly installed on the side of the middle part of the frame, a transverse moving platform fixedly installed above the radial moving platform, a front moving table and a rear moving table fixedly installed above the transverse moving platform, the front cutting tool being fixedly installed above the slide of the front moving table, and the rear cutting tool being fixedly installed above the slide of the rear moving table.

[0023] In S4, during the cutting process, the front tool performs rough machining on the roller surface, and the rear tool performs finish machining on the roller surface.

[0024] Preferably, in S5, after turning is completed and the atomizer is turned off, the heating plate is started. The heating plate heats the air at the air inlet of the blower, so that the hot air enters the ring pipe and drives the guide ring to move radially along the roller body. The hot air is sprayed out through the air nozzle to heat and dry the roller surface and remove the adhering substances on the roller surface. After the roller surface is dried and cleaned, the operation of the integrated processing assembly is stopped, the drive guide ring is positioned at one end of the roller body, the coil is de-energized, the spring pushes the adsorption plate, and the detection shaft presses the ball on the surface of the roller body. The guide ring drives the ball to move radially along the roller body, and the roller body continues to rotate. The flatness of the roller surface is detected. If the flatness is within the required range, the processing is completed. Otherwise, S4 and S5 are repeated until the processing is completed.

[0025] The present invention has the following beneficial effects:

[0026] 1. This invention utilizes ball bearings to contact the roller surface. As the detection component moves radially along the roller body and the positioning component drives the roller body to rotate, the ball bearings can make contact with all parts of the roller surface, ensuring sufficient contact and facilitating the detection of surface unevenness. By measuring the maximum relative displacement value, the flatness of the roller surface is checked, thereby determining the surface unevenness. Based on the flatness and unevenness of the roller surface, the turning depth can be flexibly adjusted, balancing turning efficiency and accuracy in roller machining.

[0027] 2. This invention, by removing dust and impurities from the roller surface, prevents impurities from becoming trapped between the balls and the roller surface during testing, thus effectively improving testing accuracy. Removing dust and impurities from the roller surface also prevents them from entering the groove at the end of the testing shaft where the balls are mounted, preventing them from affecting the rolling of the balls at the end of the testing shaft. Smooth rolling of the balls within the testing shaft allows them to roll smoothly on the roller surface as well, avoiding friction between the balls and the roller surface that could cause wear. This prevents damage to the balls and also avoids a decrease in testing accuracy.

[0028] 3. This invention uses spray cooling on the roller surface. The integrated processing component blows high-speed humidified airflow onto the roller surface. The humidified airflow has a dual cooling effect of air cooling and evaporative cooling on the front and rear cutting tools and the cut roller surface. While ensuring the cooling capacity during processing, it can also avoid the formation of liquid accumulation in the frame. This solves the problems of inconvenient cleaning and easy corrosion caused by liquid accumulation when using coolant for cooling in existing roller turning. Using these humidified airflows for cooling also blows away the metal chips produced by the front and rear cutting tools, preventing the metal chips from getting entangled in the guide ring and scratching the detection shaft and balls, or entering the groove where the detection shaft installs the balls and affecting the rotation of the balls.

[0029] 4. This invention uses a comprehensive processing component to blow high-speed airflow onto the surface of the roller. The airflow thoroughly removes impurities and water stains remaining on the roller surface, preventing impurities and water stains from damaging the balls and the grooves where the balls are mounted on the detection shaft. By repeating S3 to measure the flatness of the roller surface, it is possible to directly detect whether the processing of the roller surface meets the requirements, thus solving the problem that existing straightening machines cannot directly detect whether the processing of the roller surface meets the requirements.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0042] Please see Figure 1 - Figure 8 As shown, a high wear-resistant straightener roller surface processing technology uses a turning device for processing. The turning device includes a frame 1, a positioning component 3 for clamping the roller body 2, a comprehensive processing component 4 for cleaning and cooling the roller surface, a detection component 5 for detecting the roller surface, and a turning component 6 for processing the roller surface. The specific process includes the following steps:

[0043] S1. Use positioning component 3 to hold roller 2 in place;

[0044] S2. Use integrated processing component 4 to remove dust and impurities from the roller surface;

[0045] S3. Use the detection component 5 to detect the flatness of the roller surface to determine the cutting depth of the turning component 6; A guide ring 7 is movably arranged above the frame 1. Multiple detection components 5 are evenly spaced inside the guide ring 7. The detection component 5 includes a fixed seat 51 fixed inside the guide ring 7, a detection shaft 52 elastically connected to one end of the fixed seat 51, a ball 53 rollingly arranged at one end of the detection shaft 52, and a displacement sensor 54 fixed at the other end of the fixed seat 51. The detection end of the displacement sensor 54 abuts against the other end of the detection shaft 52. When in use, the ball 53 abuts against the roller surface, causing the guide ring 7 to drive the detection component 5 to move radially along the roller body 2. At the same time, the positioning component 3 drives the roller body 2 to rotate, and the displacement sensor 54 measures the maximum relative displacement value.

[0046] Based on this operation, the blank of the roller body 2 used in the straightening machine has concave and convex surfaces after production. In order to solve the problem of inconvenience in detecting the concavity and convexity of the roller body 2 during the existing roller body 2 turning process, the ball bearing 53 is used to contact the roller surface. When the detection component 5 moves along the radial direction of the roller body 2 and the positioning component 3 drives the roller body 2 to rotate, the ball bearing 53 can contact all parts of the roller surface, so that the ball bearing 53 and the roller surface can make sufficient contact and facilitate the detection of the concavity and convexity of the roller surface.

[0047] When the ball 53 is in contact with the roller surface, as the ball 53 passes through the concave surface of the roller body 2, the detection shaft 52 extends outward from the fixed seat 51. As the ball 53 passes through the convex surface of the roller body 2, the detection shaft 52 extends into the interior of the fixed seat 51. The displacement sensor 54 is used to measure the distance of the detection shaft 52 extending outward and extending into the fixed seat 51. The sum of the farthest extension distance and the farthest extension distance is the maximum relative displacement value.

[0048] By using this operation to measure the maximum relative displacement value, the flatness of the roller surface of roller 2 can be checked, thereby determining the unevenness of the roller surface. Based on the flatness and unevenness of the roller surface, the turning depth can be flexibly adjusted, so that turning efficiency and accuracy can be balanced in the machining of roller 2.

[0049] Removing dust and impurities from the roller surface prevents impurities from getting trapped between the balls 53 and the roller surface during inspection, thus effectively improving inspection accuracy. Removing dust and impurities from the roller surface also prevents them from entering the groove at the end of the inspection shaft 52 where the balls 53 are installed, thus preventing them from affecting the rolling of the balls 53 at the end of the inspection shaft 52. Smooth rolling of the balls 53 within the inspection shaft 52 allows them to roll smoothly on the roller surface as well, preventing friction between the balls 53 and the roller surface that could cause wear. This prevents damage to the balls 53 and also avoids a decrease in inspection accuracy.

[0050] S4. Use the integrated processing component 4 to spray and cool the roller surface, and use the turning component 6 to cut the roller body 2. The turning component 6 includes a front cutter 61 and a rear cutter 62. According to the maximum relative displacement value measured in S3, make the cutting depth of the front cutter 61 greater than half of the maximum relative displacement value, and make the cutting depth of the rear cutter 62 greater than the maximum relative displacement value.

[0051] During operation, the cutting depth is as follows: the cutting depth of the front cutter 61 is greater than half of the maximum relative displacement value but less than the maximum relative displacement value, used to remove the original concave surface of the roller 2, thus performing rough machining. The cutting depth of the rear cutter 62 is greater than the maximum relative displacement value, used to remove the original concave surface of the roller 2, thus performing finish machining. If the maximum relative displacement value is too large, exceeding the normal cutting depth, machining is performed in multiple stages until the roller surface of the roller 2 is completed.

[0052] Based on this operation, the roller surface is cooled by spraying. The integrated processing component 4 blows a high-speed humid airflow onto the roller surface. The humid airflow has a dual cooling effect of air cooling and evaporative cooling on the front tool 61, the rear tool 62, and the cut roller surface. While ensuring the cooling capacity during processing, it can also prevent the formation of liquid accumulation in the frame 1. This solves the problem of inconvenient cleaning and easy corrosion of equipment caused by liquid accumulation when using coolant for cooling in existing roller turning. Using these humid airflows for cooling also blows away the metal chips produced by the front tool 61 and the rear tool 62, preventing the metal chips from getting entangled in the guide ring 7 and causing scratches on the detection shaft 52 and the ball 53, or from entering the groove of the detection shaft 52 where the ball 53 is installed and affecting the rotation of the ball 53.

[0053] S5. Check whether the processing meets the target requirements; first use the integrated processing component 4 to remove impurities and water stains from the roller surface, then repeat S3 to measure the flatness of the roller surface. If the flatness is within the required range, the processing is complete; otherwise, repeat S4 and S5 until the processing is complete.

[0054] Based on this operation, during the rotation of the roller body 2, a high-speed airflow is blown out on the surface of the roller body 2 using the integrated processing component 4. The airflow thoroughly removes the impurities and water stains remaining on the roller surface, preventing the impurities and water stains from damaging the balls 53 and the grooves on the detection shaft 52 where the balls 53 are installed. By repeating S3 to measure the flatness of the roller surface, it is possible to directly detect whether the processing of the roller surface meets the requirements, thus solving the problem that existing straightening machines cannot directly and automatically detect whether the processing of the roller surface meets the requirements.

[0055] The positioning component 3 includes a chuck 31 movably disposed on one side of the frame 1, a movable frame 32 movably disposed on the other side of the frame 1, and an ejector pin 33 movably disposed on the side of the movable frame 32. The frame 1 is provided with a power component that drives the chuck 31 to rotate. The movable frame 32 drives the ejector pin 33 to move, so that the roller 2 can be clamped on the chuck 31.

[0056] In S1, the chuck 31 holds one end of the roller 2 of the straightener, and the moving frame 32 drives the ejector pin 33 to press against the other end of the ejector pin 33, so that the roller 2 is clamped on the frame 1.

[0057] Based on this operation, the roller 2 is locked between the chuck 31 and the ejector pin 33. In S2, S3, S4 and S5, the power assembly is used to drive the chuck 31 to rotate, which facilitates the synchronous rotation of the roller 2.

[0058] The integrated processing component 4 includes a blower 41, an atomizer 42, a ring pipe 43, and nozzles 44. The blower 41 and the atomizer 42 are fixedly mounted above the middle platform of the frame 1. The air outlet of the blower 41 and the air inlet of the atomizer 42 are connected through an air guide pipe 8. The air outlet of the atomizer 42 and the air inlet of the ring pipe 43 are connected through a flexible pipe 9. Multiple nozzles 44 are fixedly mounted on the inner side of the ring pipe 43. The multiple nozzles 44 are evenly spaced on the inner side of the ring pipe 43. The ejector pin 33 is displaced to the middle of the inner side of the ring pipe 43. The ring pipe 43 is fixedly mounted on one side of the guide ring 7. The flexible pipe 9 can be deformed. The inner diameter and outer diameter of the ring pipe 43 and the guide ring 7 are the same.

[0059] In S2, the blower 41 and atomizer 42 are started, and the power unit drives the chuck 31 to rotate, which drives the roller 2 to rotate synchronously. The guide ring 7 drives the ring tube 43 to move radially along the roller 2 from one end to the other. During this process, the blower 41 introduces outside air into the atomizer 42, and the water mist generated by the atomizer 42 is introduced into the ring tube 43 through the flexible tube 9 to form a humid airflow. The humid airflow is sprayed out through multiple air nozzles 44 to perform a dust-suppressing and comprehensive cleaning of the surface of the roller 2 until the dust and impurities on the roller surface are cleaned.

[0060] Based on this operation, the air nozzle 44 ejects a strong humidifying airflow. As the roller body 2 rotates and the annular tube 43 moves radially along the roller body 2, the airflow can moisten dust and impurities, continuously blowing away all dust and impurities on the surface of the roller body 2 and preventing dust from forming. The annular tube 43 and the guide ring 7 concentrate the airflow, forming an annular airflow on the surface of the roller body 2. This ensures that the humidifying airflow does not disperse directly after being ejected from the air nozzle 44, but flows along the roller surface, allowing the humidifying airflow to be utilized more fully and effectively moistening the roller surface.

[0061] The detection assembly 5 also includes an adsorption plate 55 fixedly mounted on the side of the detection shaft 52, a spring 56 sleeved on the side of the detection shaft 52, an iron core tube 57 sleeved on the side of the detection shaft 52, and a coil 58. The coil 58 is sleeved on the side of the iron core tube 57. The interior of the fixing seat 51 is provided with a partition plate 10 that divides the fixing seat 51 into two chambers. The adsorption plate 55 and the spring 56 are located in one chamber, and the iron core tube 57 and the coil 58 are located in the other chamber. The displacement sensor 54 is fixedly mounted on the end of the fixing seat 51. The detection end of the displacement sensor 54 passes through the fixing seat 51 and the iron core tube 57 and extends into the end of the detection shaft 52. One end of the spring 56 abuts against the adsorption plate 55, and the other end of the spring 56 abuts against the partition plate 10. When the coil 58 is energized, it generates a magnetic attraction to the adsorption plate 55.

[0062] In S2, before the guide ring 7 moves onto the roller body 2, the coil 58 is energized. The coil 58 generates a magnetic force to attract the adsorption plate 55, causing the adsorption plate 55 to pull the detection shaft 52 and the ball 53. Then, the guide ring 7 is placed on the roller body 2. Next, the current to the coil 58 is turned off, and the spring 56 pushes the adsorption plate 55, causing the detection shaft 52 and the ball 53 to move toward the roller body 2, so that the ball 53 abuts against the surface of the roller body 2.

[0063] Based on this operation, the extension and retraction of the detection shaft 52 and the ball bearing 53 are automatically adjusted during operation. After the coil 58 is energized and the adsorption plate 55 adsorbs and pulls the detection shaft 52 and the ball bearing 53, when the guide ring 7 is fitted onto the roller body 2, the detection shaft 52 and the ball bearing 53 will not obstruct the roller body 2. Before disconnecting the current of the coil 58, the current is gradually reduced to lower the magnetic force generated by the coil 58, causing the spring 56 to gradually push the adsorption plate 55, bringing the detection shaft 52 and the ball bearing 53 closer and closer to the roller surface until the ball bearing 53 contacts the roller surface, preventing collision between the ball bearing 53 and the roller surface and facilitating the protection of the ball bearing 53.

[0064] The frame 1 has a guide shaft 11 and a lead screw 12 fixedly installed on one side. The guide shaft 11 has a movable seat 13 sleeved on the side. The lead screw 12 drives the movable seat 13 to move radially along the roller body 2. The guide ring 7 is fixedly installed on one side of the movable seat 13. The lead screw 12 drives the guide ring 7 and the ring tube 43 by moving the movable seat 13.

[0065] Based on this operation, the guide shaft 11 limits the movement of the movable seat 13, and the lead screw 12 drives the movable seat 13 to move, so that the movable seat 13 drives the guide ring 7 and the ring tube 43 to move in a directional manner.

[0066] In this process, a heating plate 14 is fixedly installed at the air inlet of the blower 41. In S2, after the humid airflow removes dust and impurities from the roller surface, the ball bearing 53 continues to press against the roller surface, the guide ring 7 stops moving, and the atomizer 42 is turned off. Then, the heating plate 14 is activated, and the heating plate 14 heats the air at the air inlet of the blower 41, so that the hot air enters the ring pipe 43. After the hot air is sprayed out through the air nozzle 44, it heats the detection shaft 52 and the ball bearing 53 located inside the guide ring 7, so that the ball bearing 53 rolls at the end of the detection shaft 52. After the ball bearing 53 is heated, it heats the inner groove where the ball bearing 53 is installed at the end of the detection shaft 52. The moisture on the surface of the inner groove and the ball bearing 53 is dried. After drying, the coil 58 is energized, so that the adsorption plate 55 is magnetically attracted to pull the detection shaft 52 and the ball bearing 53 away from the roller surface.

[0067] Based on this operation, during the turning of a large number of rollers 2, a large amount of water mist will be generated and enter the air, making the turning environment relatively humid. By setting a heating plate 14 at the air inlet of the blower 41, the air heated by the heating plate 14 enters the blower 41 from the air inlet, which facilitates the heating of the internal blades of the blower 41 and the corresponding parts in contact with the air, preventing the internal blades of the blower 41 and the corresponding parts in contact with the air from rusting, and thus improving the service life of the blower 41.

[0068] After removing dust and impurities from the roller surface using a humid airflow, a hot airflow is then used to dry the detection shaft 52, the inner groove in the detection shaft 52, and the balls 53 in a timely manner. This can prevent the detection shaft 52, the inner groove in the detection shaft 52, and the balls 53 from rusting, and at the same time, it can prevent moisture from entering the fixed seat 51 along with the detection shaft 52 and causing damage to the internal structure of the fixed seat 51.

[0069] In step S4, before cutting, both the guide ring 7 and the turning assembly 6 move to one end of the roller body 2. The guide ring 7 is in front of the moving direction of the turning assembly 6. The comprehensive processing assembly 4 sprays humid airflow onto the roller surface again. When the front cutter 61 and the rear cutter 62 cut the roller body 2, the guide ring 7, the front cutter 61, and the rear cutter 62 move synchronously. The ring pipe 43 and the guide ring 7 prevent the humid airflow from spreading. The humid airflow cools the roller surface during the cutting process. The airflow also generates a thrust along the roller surface on the cut chips, causing the chips to fall along the roller surface. This guides the discharge of chips and prevents chips from splashing and causing safety hazards.

[0070] Based on this operation, the amount of water mist generated by the humidifying airflow used for cooling is greater than the amount of water mist generated during S2 when removing dust and impurities from the roller surface. The annular pipe 43 and guide ring 7 concentrate the airflow, forming an annular airflow. This not only prevents the humidifying airflow from diffusing but also increases the airflow rate and velocity on the roller body 2 surface, facilitating better utilization of the humidifying airflow and preventing rapid diffusion after ejection. The humidifying airflow passes over the front cutter 61, the rear cutter 62, and the surface of the roller body 2, cooling them and rapidly carrying away heat.

[0071] The turning assembly 6 also includes a radial moving platform 63 fixedly installed on the side of the middle part of the frame 1, a transverse moving platform 64 fixedly installed above the radial moving platform 63, a front moving table 65 fixedly installed above the transverse moving platform 64, and a rear moving table 66 fixedly installed above the transverse moving platform 64. The front cutting tool 61 is fixedly installed above the slide of the front moving table 65, and the rear cutting tool 62 is fixedly installed above the slide of the rear moving table 66.

[0072] In S4, during the cutting process, the front tool 61 performs rough machining on the roller surface, and the rear tool 62 performs finish machining on the roller surface.

[0073] Based on this operation, the roughing and finishing of the roller surface can be carried out simultaneously, which can improve processing efficiency.

[0074] In step S5, after turning is completed and atomizer 42 is turned off, heating plate 14 is started. Heating plate 14 heats air at the air inlet of blower 41, so that hot air enters ring pipe 43 and drives guide ring 7 to move radially along roller body 2. After hot air is sprayed out through air nozzle 44, the roller surface is heated and dried and the adhering substances on the roller surface are removed. After the roller surface is dried and cleaned, the operation of the integrated processing component 4 is stopped, and the drive guide ring 7 is positioned at one end of roller body 2. Then, coil 58 is de-energized, so that spring 56 pushes adsorption plate 55, causing detection shaft 52 to press ball 53 onto the surface of roller body 2. Guide ring 7 drives ball 53 to move radially along roller body 2. Roller body 2 continues to rotate and the flatness of roller surface is detected. If the flatness is within the required range, the processing is completed. Otherwise, repeat steps S4 and S5 until the processing is completed.

[0075] Based on this operation, after turning, the heating plate 14 heats the air, which in turn dries the inside of the blower 41. The hot airflow heats and dries the roller surface, the detection shaft 52, and the balls 53, and removes any adhering substances from their surfaces, preventing impurities from easily adhering to the roller body 2 due to moisture. It also prevents the detection shaft 52 and balls 53 from becoming damp and easily corroded during the operation of checking the flatness of the roller surface.
