Description

Technical Field

[0001] This invention relates to the field of arc surface grinding technology, and more specifically to a processing device and method for arc-shaped surfaces of steel templates. Background Technology

[0002] Steel formwork is a temporary support structure widely used in construction engineering. Its main function is to provide molds and supports for the molding of cast-in-place concrete components until the concrete hardens to the predetermined strength. The grinding and polishing process of the curved surface of steel formwork is an important part of the processing of the curved surface of steel formwork. However, the existing grinding and polishing equipment for the curved surface of steel formwork generates debris and dust during actual grinding. These debris are scattered in various corners of the equipment and will accumulate into a dust layer over time, affecting the heat dissipation of the equipment and even damaging the equipment. In addition, debris remains on the curved surface after grinding and polishing of steel formwork. This debris needs to be collected and processed in a timely and labor-intensive manner, which increases labor costs. To address these issues, we propose a processing device and method for the curved surface of steel formwork. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel template arc surface processing device and method to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel template arc surface processing device, comprising a push rod grinding assembly, the push rod grinding assembly comprising a machine tool frame, a cylinder being installed on one side of the inside of the machine tool frame, a rotating shaft being installed at one end of the cylinder being installed, a grinding head being installed at one end of the rotating shaft, a rotating fan assembly being installed on the side of the grinding head, the rotating fan assembly comprising a fan plate, an installation plate being installed on the other side of the inside of the machine tool frame, a dust inlet and a rotating cylinder assembly being installed on both sides of the installation plate respectively, and a tail bin being installed at one end of the rotating cylinder assembly; Driven by the rotating shaft, the rotating fan blade assembly transfers the grinding debris from one side of the mounting plate to the other side. The grinding head drives the rotating cylinder assembly to generate negative pressure airflow, which sucks the debris into the dust chamber and transfers it to the tail chamber for storage. The fan blade is further pushed by the cylinder and detaches from the mounting plate. Under the action of centrifugal force, it is placed horizontally and sweeps away the debris on the arc surface of the steel template during rotation. The fan blades are tilted at both ends and have a backward-tilted blade design at the top. The tilt angles at both ends of the fan blades are set in the range of 20° to 30°.

[0009] Furthermore, the dust collection assembly includes a mounting plate, the bottom of which is fixedly connected to one end of the top of the flat plate, and the mounting plate and the fixed plate are respectively located at opposite ends of the top of the flat plate. A circular hole is provided in the middle of one side of the mounting plate, and a dust inlet is fixedly connected to one side of the mounting plate, with the dust inlet located below the circular hole. A strip-shaped groove is provided at the top of the dust inlet. Two rotating drum assemblies are rotatably sleeved on the other side of the mounting plate. One end of the two rotating drum assemblies is fixedly connected to a tail chamber, and the two rotating drum assemblies are fixedly connected to the dust inlet. A feeding assembly is fixedly connected to the top of the mounting plate.

[0010] Furthermore, the rotary drum assembly includes a drum, the side of which is provided with a protruding strip, and a turbine fan is fixedly sleeved on the inner side of one end of the drum.

[0011] Furthermore, the feeding assembly includes a second cylinder, the top end of which is fixedly connected to the top end of the mounting plate, and the bottom end of the second cylinder is fixedly connected to the mounting plate assembly. A clamping assembly is slidably sleeved on the inner side of the mounting plate assembly.

[0012] Furthermore, the mounting plate assembly includes a base plate, the top of which is fixedly connected to the bottom of the second cylinder, and two load-bearing plates are fixedly connected to the bottom of the base plate. Load-bearing rods are fixedly connected to the bottom ends of one side of each of the two load-bearing plates, and pulleys are rotatably sleeved at one end of each of the two load-bearing rods. A servo motor is fixedly connected to the middle of the bottom of the base plate, and gears are fixedly connected to the drive end of the servo motor. The clamping assembly includes an arc-shaped sleeve plate with arc grooves on both sides. The pulley moves within the arc grooves. An extension plate is fixedly connected to both sides of the arc-shaped sleeve plate, and the extension plate is located below the arc groove. Two support rods are fixedly connected to one side of each of the two extension plates, and a clamping plate is fixedly connected to one end of each of the four support rods. Air passages are provided at both ends of the two extension plates, and the support rods are slidably sleeved inside the air passages. An air pump is fixedly connected to both ends of the two arc-shaped sleeve plates, and the air pump is fixedly connected to the air passages. A rack is evenly provided on the top of the arc-shaped sleeve plate, and the rack meshes with a gear.

[0013] A method for processing the curved surface of steel formwork, using a steel formwork curved surface processing device as described above, includes the following steps: S1. When the cylinder pushes the grinding head forward to grind using the motor to drive the rotating shaft, the limiting pin is pressed against the round hole in the mounting plate, so that the fan plate will not unfold due to centrifugal force when rotating at high speed, and the fan plate will remain tilted under high speed. S2. The grinding head rotates, which drives the drum to rotate, which in turn causes the turbofan to rotate, creating a negative pressure airflow inside the drum. When the rotating fan blade assembly rotates at high speed, the tilted design of the fan blades causes the rotating fan blade assembly to generate airflow during rotation. S3. The airflow generated by the rotating fan blade assembly draws the debris produced by the grinding head from one side of the mounting plate to the other side. Then, the negative pressure airflow in the roller further draws the debris into the dust bin, and then transfers it to the tail bin for storage. This process solves the problem that existing steel template arc surface grinding and polishing devices produce debris and dust during actual grinding. These debris are scattered in various corners of the equipment and will accumulate into a dust layer over time, affecting the heat dissipation of the equipment and even damaging the equipment. S4. When the grinding head finishes grinding, the cylinder pushes further, causing the limit pin to disengage from the round hole of the mounting plate. The fan plate loses the obstruction inside the round hole of the mounting plate and remains horizontal under the action of centrifugal force. S5. The horizontal fan plate sweeps away the grinding debris on the inner side of the curved surface of the steel template while rotating, and the rotating drum assembly continues to rotate under the drive of the grinding head to absorb the debris swept away by the fan plate. This process avoids the problem that the curved surface of the steel template will have residual debris after grinding and polishing, which would require centralized treatment later, which is time-consuming, labor-intensive and increases labor costs.

[0014] The technical effects and advantages of this invention are as follows: 1. The motor drives the rotating shaft to rotate. When the cylinder pushes the grinding head forward for grinding, the limiting pin abuts against the round hole in the mounting plate, preventing the fan plate from unfolding due to centrifugal force during high-speed rotation. This keeps the fan plate tilted during high-speed rotation. The rotation of the grinding head drives the drum to rotate, which in turn causes the turbofan to rotate. A negative pressure airflow is formed inside the drum. When the rotating fan blade assembly rotates at high speed, the tilted design of the fan plate generates airflow. The airflow generated by the rotating fan blade assembly draws the grinding debris generated by the grinding head from one side of the mounting plate to the other side. The negative pressure airflow in the drum further draws the debris into the dust bin, and then transfers it to the tail bin for storage. This process solves the problem that existing steel template arc surface grinding and polishing devices generate debris and dust during actual grinding. These debris are scattered in various corners of the equipment and accumulate into a dust layer over time, affecting the heat dissipation of the equipment and even damaging the equipment.

[0015] 2. Once the grinding head has finished grinding, the cylinder pushes it further, causing the limit pin to disengage from the round hole in the mounting plate. The fan plate, no longer obstructed by the inner side of the round hole in the mounting plate, remains horizontal under the action of centrifugal force. At this time, the horizontal fan plate sweeps away the grinding debris on the inner side of the arc surface of the steel template while rotating, while the rotating drum assembly continues to rotate under the drive of the grinding head, absorbing the debris swept away by the fan plate. This process avoids the problem of residual debris on the arc surface of the steel template after grinding and polishing, which would require centralized processing later, wasting time and effort and increasing labor costs.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The steel template arc surface processing device and method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1 The present invention provides a steel template arc surface processing device, including a push rod grinding assembly 1, a drill bit assembly 2 fixedly connected to one side of the push rod grinding assembly 1, a dust collection assembly 3 fixedly connected to the inner side of the push rod grinding assembly 1, and a feeding assembly 4 fixedly connected to the top of the dust collection assembly 3.

[0020] In this embodiment, it is necessary to further explain that the push rod grinding assembly 1 and the dust extraction assembly 3 solve the problem that existing steel template arc surface grinding and polishing devices generate debris and dust during actual grinding. These debris are scattered in various corners of the equipment and accumulate into a dust layer over time, affecting the heat dissipation of the equipment and even damaging the equipment. The push rod grinding assembly 1 and the drill bit assembly 2 avoid the problem that debris will remain on the arc surface after grinding and polishing the steel template. These debris need to be centrally processed afterward, which is time-consuming and labor-intensive, increasing labor costs. The specific structure and working principle of the above components will be explained in detail later.

[0021] Reference Figure 2 and Figure 3The push rod grinding assembly 1 includes a machine tool frame 101. A flat plate is fixedly sleeved on the inner side of the machine tool frame 101. A fixing plate 102 is fixedly connected to the top of the flat plate. A cylinder 103 is fixedly sleeved on one side of the fixing plate 102. Track plates 104 are fixedly connected to both ends of the other side of the fixing plate 102. A connecting slide 105 is slidably sleeved on the top of the track plate 104. One side of the connecting slide 105 is fixed to the drive end of the cylinder 103. A motor is fixedly sleeved on the top of the connecting slide 105. A rotating shaft 106 is rotatably sleeved on the inner side of the connecting slide 105. A transmission belt is fixedly connected to one end of the rotating shaft 106, and the other end of the transmission belt is fixedly connected to the drive end of the motor.

[0022] In this embodiment, it is necessary to further explain that when the drive end of cylinder 103 extends or retracts, it drives the connecting slide 105 to slide horizontally along the track plate 104, thereby pushing the rotating shaft 106 and the grinding head 201 closer to or further away from the curved surface of the steel template to be processed; the motor drives the rotating shaft 106 to rotate at high speed through the transmission belt, which in turn drives the grinding head 201 and the rotating fan blade assembly 202 to rotate synchronously, realizing the grinding operation and the initial blowing of debris. This structure ensures that the feed motion of the grinding head 201 is stable and controllable, and provides a power basis for subsequent dust suction and chip scraping actions.

[0023] Reference Figure 4 The drill bit assembly 2 includes a grinding head 201, one end of which is fixedly connected to a round pin, and one end of the round pin is fixedly connected to a rotating shaft 106. Several rotating fan blade assemblies 202 are fixedly connected to the sides of the grinding head 201 and the round pin.

[0024] In this embodiment, it should be specifically noted that the rotating fan blade assembly 202 rotates synchronously with the grinding head 201.

[0025] Reference Figure 5 The rotating fan blade assembly 202 includes a fan plate 2021. The fan plate 2021 is inclined at both ends and at the top. The inclination angles at both ends of the fan plate 2021 are set in the range of 20° to 30°. A brush is fixedly connected to the top of the fan plate 2021. A limit pin 2022 is fixedly connected to the top of the fan plate 2021. A hinge base 2023 is rotatably connected to the bottom of both ends of the fan plate 2021. The bottom of one hinge base 2023 is fixedly connected to the side of the grinding head 201. A spring is fixedly connected to the bottom of the other hinge base 2023. The bottom end of the spring is fixedly connected to the side of the round pin. The spring has a telescopic tube inside. The top and bottom of the telescopic tube are fixedly connected to the bottom of one hinge base 2023 and the side of the round pin, respectively.

[0026] In this embodiment, it should be specifically noted that the fan plate 2021 adopts a backward-inclined blade design, and the tilt angle at both ends of the fan plate 2021 is set in the range of 20° to 30° to achieve efficient pressure conversion. The brush is a conventional technical means and is not shown in the figure. The fan plate 2021 is rotatably connected to the side of the grinding head 201 and the side of the round pin through two hinged bases 2023, forming a swingable connection structure. The hinged base 2023 connected to the round pin is provided with a spring and a telescopic tube below it. The spring provides preload force so that the fan plate 2021 remains in a closed or tilted posture in its natural state. The telescopic tube plays a guiding and dustproof role, ensuring that the spring remains stable when compressed or extended.

[0027] Reference Figure 6 and Figure 7 The dust collection component 3 includes a mounting plate 301. The bottom of the mounting plate 301 is fixedly connected to one end of the top of the flat plate, and it and the fixing plate 102 are respectively located at the two ends of the top of the flat plate. A round hole is provided in the middle of one side of the mounting plate 301. A dust inlet 302 is fixedly connected to one side of the mounting plate 301, and the dust inlet 302 is located below the round hole. A strip-shaped groove is provided at the top of the dust inlet 302. Two rotating drum assemblies 303 are rotatably sleeved on the other side of the mounting plate 301. One end of the two rotating drum assemblies 303 is fixedly connected to the tail chamber 304, and the two rotating drum assemblies 303 are fixedly connected to the dust inlet 302. A feeding component 4 is fixedly connected to the top of the mounting plate 301.

[0028] In this embodiment, it is necessary to specifically explain that the circular hole in the middle of the mounting plate 301 is used for the grinding head 201 and the rotating fan blade assembly 202 to pass through, so that the airflow generated by the rotating fan blade assembly 202 can blow the debris from one side of the mounting plate 301 to the other side. The limiting pin 2022 abuts against the inside of the circular hole in the early stage of grinding to ensure that the fan blade 2021 remains in an inclined state. The dust inlet 302 is located below the circular hole, and the strip groove at its top serves as the debris inlet. The debris blown by the rotating fan blade assembly 202 falls into the dust inlet 302 through the strip groove with the assistance of gravity. The rotating drum assembly 303 is driven to rotate by the grinding head 201 through contact friction or transmission. The feeding assembly 4 is fixed on the top of the mounting plate 301 and is used to clamp and transport the steel template workpiece so that its arc surface is aligned with the grinding head 201 for processing. Overall, the dust collection component 3 and the rotating fan component 202 form a two-stage dust removal system that combines blowing and suction: the first stage is the airflow generated by the rotating fan component 202 that blows the debris from the grinding area to the vicinity of the dust inlet 302; the second stage is the negative pressure generated by the rotating drum component 303 that actively sucks in the debris and stores it in a concentrated manner, effectively preventing the debris from falling into the equipment and solving the problem of debris accumulation affecting heat dissipation and damaging the equipment.

[0029] When the grinding head 201 finishes grinding, the cylinder 103 pushes further, causing the limit pin 2022 to disengage from the round hole of the mounting plate 301. The fan plate 2021, no longer blocked by the inner side of the round hole of the mounting plate 301, remains horizontal under the action of centrifugal force. At this time, the horizontal fan plate 2021 sweeps away the grinding debris on the inner side of the arc surface of the steel template while rotating, while the rotating drum assembly 303 continues to rotate under the drive of the grinding head 201, absorbing the debris swept away by the fan plate 2021. This process avoids the problem that debris will remain on the arc surface after the steel template is ground and polished. These debris need to be centrally processed later, which is time-consuming and labor-intensive, and increases labor costs.

[0030] Reference Figure 8 The rotary drum assembly 303 includes a drum 3031, the side of which is provided with a protruding strip, and a turbo fan 3032 is fixedly sleeved on the inner side of one end of the drum 3031.

[0031] In this embodiment, it is necessary to further explain that the protrusions on the side of the roller 3031 are used to form contact friction transmission with the cylindrical surface of the grinding head 201 or related transmission components: when the grinding head 201 rotates at high speed, the roller 3031 is driven to rotate synchronously by friction, without the need for an additional motor drive, which simplifies the structure. When the roller 3031 rotates, the turbine fan 3032 fixedly sleeved on its inner side rotates at high speed, forming a negative pressure airflow inside the roller 3031 and in the dust inlet 302 connected to it. The negative pressure airflow draws the grinding debris that falls into the dust collection chamber 302 into the roller 3031 through the strip-shaped slot at the top of the dust collection chamber 302, and finally transports it to the tail chamber 304 for centralized storage. The two rotating drum assemblies 303 are installed in parallel, which increases the total flow rate of the negative pressure dust collection on the one hand, and can still provide suction on the other side when the contact between one roller 3031 and the grinding head 201 is poor, thus improving the reliability of the system. In addition, the contact between the convex strip and the grinding head 201 can also play a certain role in decelerating or stabilizing the rotation speed, preventing the grinding head 201 from stalling due to sudden load changes. This realizes the linkage between the grinding head 201 and the dust collection mechanism, eliminating the need for an independent power source and reducing energy consumption and manufacturing costs.

[0032] When the motor drives the rotating shaft 106 to rotate, and the cylinder 103 pushes the grinding head 201 forward for grinding, the limiting pin 2022 abuts against the round hole in the mounting plate 301, preventing the fan blade 2021 from unfolding due to centrifugal force during high-speed rotation. This keeps the fan blade 2021 tilted during high-speed rotation. The rotation of the grinding head 201 drives the roller 3031 to rotate, which in turn causes the turbofan 3032 to rotate. A negative pressure airflow is formed inside the roller 3031. When the rotating fan blade assembly 202 rotates at high speed, the tilted design of the fan blade 2021 causes the rotation... When the fan blade assembly 202 rotates, it generates airflow. The airflow generated by the rotating fan blade assembly 202 draws the debris produced by the grinding head 201 from one side of the mounting plate 301 to the other side. Then, the negative pressure airflow in the roller 3031 further draws the debris into the dust bin 302, and then transfers it to the tail bin 304 for storage. This process solves the problem that existing steel template arc surface grinding and polishing devices generate debris and dust during actual grinding. These debris are scattered in various corners of the equipment and will accumulate into a dust layer over time, affecting the heat dissipation of the equipment and even damaging the equipment.

[0033] When cylinder 103 is activated, the connecting slide 105 slides horizontally along the track plate 104, pushing the grinding head 201 towards the arc-shaped surface of the steel template to be processed. At this time, the limiting pin 2022 at the top of the fan plate 2021 abuts against the circular hole in the middle of the mounting plate 301. The motor is started, driving the rotating shaft 106 to rotate via the transmission belt, thereby causing the grinding head 201 and the rotating fan blade assembly 202 mounted on its side to rotate synchronously at high speed. During the grinding process, the limiting pin 2022 at the top of the fan plate 2021 abuts against the circular hole in the middle of the mounting plate 301, relying on the motor inside the circular hole. Mechanical obstruction overcomes the centrifugal force generated when the fan plate 2021 rotates, forcing the fan plate 2021 to be unable to unfold outward, thus maintaining an inclined state with an angle of 20° to 30° at both ends under high-speed rotation. When the grinding process of the arc surface of the steel template is basically completed, the cylinder 103 continues to push the grinding head 201 forward, and the limit pin 2022 moves further forward, completely disengaging from the round hole of the mounting plate 301, thus losing the radial obstruction inside the round hole. Under the action of the centrifugal force generated by high-speed rotation, the fan plate 2021 unfolds outward around the hinge base 2023, and finally maintains a horizontal position.

[0034] Reference Figure 9 The feeding assembly 4 includes a second cylinder 401, the top of which is fixedly connected to the top of the mounting plate 301, and the bottom of the second cylinder 401 is fixedly connected to the mounting plate assembly 402. The clamping assembly 403 is slidably sleeved on the inner side of the mounting plate assembly 402.

[0035] In this embodiment, it is necessary to further explain that cylinder 401, as a lifting drive element, has its top fixed to the top of mounting plate 301 and its bottom connected to mounting plate assembly 402. The extension and retraction of cylinder 401 can drive the mounting plate assembly 402 and clamping assembly 403 to move up and down as a whole, thereby adjusting the position of the steel template workpiece in the vertical direction, aligning the workpiece's arc-shaped surface with the grinding head 201. Mounting plate assembly 402 includes a base plate 4021, a load-bearing rod 4022, pulleys, and a servo motor, etc., with clamping assembly 403 slidably sleeved on its inner side. The arc-shaped sleeve in clamping assembly 403... The plate 4031 has arc grooves on both sides, which cooperate with the pulleys on the mounting plate assembly 402 to achieve sliding along an arc trajectory. At the same time, the rack on the top of the arc-shaped sleeve plate 4031 meshes with the gear driven by the servo motor at the bottom of the mounting plate assembly 402. Under the drive of the servo motor, the clamping assembly 403 can move precisely along the arc trajectory, keeping the arc surface of the steel template workpiece in contact with the grinding head 201. The clamping assembly 403 also includes an extension plate 4032, an air duct, a support rod, a clamping plate 4033, and an air pump. The air pump drives the support rod to extend and retract through the air duct, thereby clamping or releasing the steel template workpiece by the clamping plate 4033. This feeding assembly 4 realizes automatic clamping, lifting, and arc feeding of the arc surface of the steel template, ensuring the relative positional accuracy of the workpiece and the grinding head 201 during the grinding process and improving the degree of automation of the processing.

[0036] Reference Figure 10 The mounting plate assembly 402 includes a base plate 4021. The top of the base plate 4021 is fixedly connected to the bottom of the cylinder 401. Two load-bearing plates are fixedly connected to the bottom of the base plate 4021. Load-bearing rods 4022 are fixedly connected to the bottom end of one side of each load-bearing plate. A pulley is rotatably sleeved at one end of each load-bearing rod 4022. A servo motor is fixedly connected to the middle of the bottom of the base plate 4021, and a gear is fixedly connected to the drive end of the servo motor. The clamp assembly 403 includes an arc-shaped sleeve plate 4031. Both sides of the arc-shaped sleeve plate 4031 are provided with arc grooves, and pulleys move within the arc grooves. Both sides of the arc-shaped sleeve plate 4031 are fixedly connected to extension plates 4032, and the extension plates 4032 are located below the arc grooves. Two support rods are fixedly connected to one side of each of the two extension plates 4032, and one end of each of the four support rods is fixedly connected to a clamping plate 4033. Both ends of the two extension plates 4032 are provided with air passages, and the support rods slide inside the air passages. Both ends of the two arc-shaped sleeve plates 4031 are fixedly connected to air pumps, and the air pumps are fixedly connected to the air passages. The top of the arc-shaped sleeve plate 4031 is uniformly provided with racks, and the racks mesh with gears.

[0037] In this embodiment, it is necessary to further explain that the mounting plate assembly 402 and the clamping assembly 403 together constitute an automatic feeding and clamping system. The cylinder 401 drives the base plate 4021 and all the components below it to rise and fall as a whole, thereby adjusting the height of the steel template workpiece in the vertical direction so that its arc surface is aligned with the grinding head 201. The servo motor drives the gear to rotate, and through the meshing transmission of the rack and pinion, the arc-shaped sleeve 4031 slides in an arc shape along the direction of the arc groove. The arc groove and the pulley cooperate to guide and limit the movement, ensuring that the movement trajectory of the arc-shaped sleeve 4031 is consistent with the arc surface of the steel template, thereby realizing the arc feeding of the workpiece and ensuring that the grinding head 201 always fits against the arc surface for processing. The air passage on the extension plate 4032 is connected to the air pump. When the air pump is filled with air, the air pressure pushes the support rod to extend outward along the air passage, thereby driving the clamping plate 4033 to clamp the steel template workpiece. When the air pump exhausts air, the support rod retracts and the clamping plate 4033 releases the workpiece. The clamping plate 4033 has a four-support rod structure, which ensures stable clamping and uniform force distribution, so that the clamping assembly 403 can adapt to the curved surface of the steel template with different radii of curvature. At the same time, it realizes automatic lifting, arc-shaped contour feeding and rapid clamping and release, which improves processing accuracy and production efficiency and reduces manual operation.

[0038] The working principle of this invention: A method for processing the curved surface of steel formwork, using the above-described processing device for the curved surface of steel formwork, includes the following steps: S1. When the motor drives the rotating shaft 106 to rotate and the cylinder 103 pushes the grinding head 201 forward for grinding, the limit pin 2022 abuts against the round hole of the mounting plate 301, so that the fan plate 2021 will not unfold due to centrifugal force when rotating at high speed, and the fan plate 2021 will remain tilted under high speed rotation. S2. The grinding head 201 rotates, driving the drum 3031 to rotate, which in turn causes the turbofan 3032 to rotate, forming a negative pressure airflow inside the drum 3031. When the rotating fan blade assembly 202 rotates at high speed, the tilted design of the fan plate 2021 causes the rotating fan blade assembly 202 to generate airflow when rotating. S3. The airflow generated by the rotating fan blade assembly 202 draws the debris produced by the grinding head 201 from one side of the mounting plate 301 to the other side. Then, the negative pressure airflow in the roller 3031 further draws the debris into the dust bin 302, and then transfers it to the tail bin 304 for storage. This process solves the problem that existing steel template arc surface grinding and polishing devices generate debris and dust during actual grinding. These debris are scattered in various corners of the equipment and will accumulate into a dust layer over a long period of time, affecting the heat dissipation of the equipment and even damaging the equipment. S4. When the grinding head 201 finishes grinding, the cylinder 103 pushes further, causing the limit pin 2022 to disengage from the round hole of the mounting plate 301. The fan plate 2021 loses the obstruction inside the round hole of the mounting plate 301 and remains horizontal under the action of centrifugal force. S5. The horizontal fan plate 2021 sweeps away the grinding debris on the inner side of the arc surface of the steel template while rotating, while the rotating drum assembly 303 continues to rotate under the drive of the grinding head 201, absorbing the debris swept away by the fan plate 2021. This process avoids the problem that the arc surface of the steel template will have residual debris after grinding and polishing, which would require centralized treatment later, which is time-consuming, labor-intensive, and increases labor costs.
