Description

Technical Field

[0001] This invention belongs to the field of wing radiator manufacturing technology, and particularly relates to a cutting and grinding assembly and method for wing flat tubes. Background Technology

[0002] Traditional wing-shaped flat tube processing typically involves multiple independent machines performing the tooth cutting, cutting, and grinding processes in stages. Manual transfer and repositioning between these processes are required, resulting in low processing efficiency, low automation, and poor positioning accuracy. Tooth cutting and cutting operations often employ a stop-and-feed method, severely disrupting the production cycle and making it difficult to process short materials. Furthermore, the burrs on the cut end face require a separate grinding process, further reducing production efficiency. Summary of the Invention

[0005] The cutting and cutting mechanism includes a cutting assembly and a cutting assembly that can move synchronously and horizontally along the material guide channel. The cutting assembly is used to cut the excess portion of the wings on both sides of the winged flat tube in the material guide channel during the movement.

[0022] A first vertical cylinder is fixedly installed on the top of the front fixed plate, and the piston rod end of the first vertical cylinder is connected to a liftable first baffle plate; when the first baffle plate falls to the blocking position, it can block the entrance channel.

[0023] Furthermore, the cutting tooth assembly includes:

[0024] The first support frame is disposed within the support frame;

[0025] The tool holder is mounted on the first support frame in a height-adjustable manner via a vertical guide rail pair, and its bottom is provided with a cutting tool for cutting the wings on both sides of the flying wing flat tube;

[0026] The first motor is mounted on the first support frame via a first motor mount, and its output shaft is connected to a vertically arranged first lead screw via a coupling.

[0027] The first lead screw nut is threadedly engaged with the first lead screw and is fixedly connected to the tool holder;

[0030] At least one pressing cylinder is fixedly installed on the first support frame, and its piston rod is connected to the second upper clamping plate assembly for driving it to press down to fix the flying wing flat tube.

[0031] Furthermore, the truncation component includes:

[0045] A fourth motor, connected to the fourth lead screw, is used to drive its rotation.

[0046] Another aspect of the present invention discloses a working method for the above-mentioned cutting and grinding assembly for wing-shaped flat tubes, comprising the following steps:

[0047] S1. The wing flat tube to be processed is introduced into the feeding mechanism and moves along the guide channel under the clamping and pushing of the first gripper cylinder assembly until it touches the first baffle plate.

[0048] S2. After the first baffle is lifted, the flying wing flat tube enters the tooth cutting process; the first and second linkage drive mechanisms operate alternately, and the tooth cutting assembly and the cutting assembly perform independent tooth cutting and cutting operations in horizontal synchronous movement respectively;

[0049] S3. The cut-off wing flat tube enters the grinding mechanism, where the upper and lower grinding components rotate and brush the upper and lower surfaces of both sides of the wing flat tube to remove burrs and flash from the end face and both sides, finally obtaining the finished product.

[0050] The advantages and technical effects of this invention are as follows:

[0051] In terms of functional integration and process integrity, this assembly organically integrates the three processes of tooth cutting, fixed-length cutting, and end-face grinding into a single machine, achieving integrated continuous processing from blank feeding to finished product output. Compared to the traditional process that requires separate tooth cutting, cutting, and grinding equipment, this assembly reduces the number of workpiece transfers between multiple machines, not only improving production efficiency but also avoiding positioning errors caused by multiple clamping operations, significantly enhancing processing accuracy and product consistency.

[0052] This invention integrates the cutting tooth assembly and the cutting component into the same support frame, and sets up a first linkage drive mechanism to drive the two components to reciprocate as a whole. With the synchronous operation of the first and second gripping cylinder assemblies and the second linkage drive mechanism, the cutting tooth and cutting operations can be carried out continuously without stopping the machine during the movement. Moreover, the vertical cutting tooth and cutting operations do not interfere with each other, and there is no need to stop the machine to feed materials, which greatly improves production efficiency.

[0053] In terms of working environment and cleanliness, this assembly effectively controls metal shavings, dust and other pollutants generated during cutting, sawing and grinding within the processing area by setting up fully enclosed or semi-enclosed protective covers in each processing area. This avoids the pollution of the workshop environment by flying debris, significantly improves the cleanliness of the work site, and meets the requirements of modern green manufacturing and clean production.

[0072] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0073] It should be noted that the terms "front" and "rear" refer to the side closer to the feed in the conveying direction of the wing-shaped flat tube, which is "rear" and the side closer to the discharge in the conveying direction, which is "front"; "left" and "right" refer to the positions on the left and right sides when facing the conveying direction of the wing-shaped flat tube.

[0074] like Figures 1 to 3As shown, this embodiment relates to a cutting and grinding assembly for wing-shaped flat tubes. This assembly is integrated on the same worktable 1 and sequentially includes a feeding mechanism 2, a cutting and grinding mechanism 5 along the conveying direction of the wing-shaped flat tube. The feeding mechanism 2, the cutting and grinding mechanism 5 are sequentially connected and linked through a material guide channel to achieve integrated automatic processing of the wing-shaped flat tube from material feeding, double-sided wing cutting, fixed-length cutting, to end-face deburring and grinding.

[0075] The wing-shaped flat tube is a strip-shaped metal profile to be processed. Its cross-section has a symmetrical structure, including upper and lower protruding ridges and wings located on both sides of the flat tube base. During the processing, the wings on both sides need to be dimensionally adjusted and cut to a preset length. Finally, the cut end face is deburred and polished to obtain a finished wing-shaped flat tube that meets the requirements.

[0076] The material guide channel is used for the transmission, guidance, and position limiting of the wing flat tube during processing. It includes an upper clamping plate assembly and a lower clamping plate assembly. The bottom of the upper clamping plate assembly is provided with an upper slot that matches the top protrusion of the wing flat tube, and the top of the lower clamping plate assembly is provided with a lower slot that matches the bottom protrusion of the wing flat tube. Through the cooperation of the upper and lower slots, the wing flat tube is stably guided in the conveying direction and limited in the vertical direction.

[0077] In some specific embodiments, such as Figure 4 , 5 As shown, the feeding mechanism 2 includes an inlet 23, a front positioning component 24, a rear positioning component 25, and a clamping device; the inlet 23 has a trumpet-shaped structure, with its large end facing the feeding side and its small end connected to the guiding channel, so that the wing flat tube can be smoothly guided into the subsequent processing channel by manual or mechanical means.

[0078] The feeding mechanism 2 includes a first upper clamping plate assembly 21 and a first lower clamping plate assembly 22. The bottom of the first upper clamping plate assembly 21 is provided with a T-shaped hole that runs through the conveying direction of the wing flat tube. A replaceable T-shaped guide strip 211 is embedded in the T-shaped hole. The bottom of the T-shaped guide strip 211 is provided with a through slot that engages with the upper convex edge of the wing flat tube. By replacing the guide strip with a slot of a different size, different specifications of wing flat tubes can be adapted, avoiding the need to disassemble the entire upper guide plate and significantly improving the changeover efficiency.

[0079] The front positioning assembly 24 and the rear positioning assembly 25 have the same structure and are fixed at the front and rear ends of the material guide channel of the feeding mechanism 2, respectively. Both the front and rear positioning assemblies include a first frame and a second frame arranged symmetrically on the left and right. The top of the first frame and the second frame are respectively provided with a first waist hole extending in the vertical direction. A bolt for connecting the first upper clamping plate assembly 21 is inserted into the first waist hole. By loosening the bolt, the position of the first upper clamping plate assembly 21 can be adjusted up and down along the waist hole, thereby adjusting the vertical distance between the first upper clamping plate assembly 21 and the first lower clamping plate assembly 22 to accommodate wing flat tubes of different height specifications and improve the versatility of the equipment.

[0080] The clamping device includes two first gripper cylinder assemblies 26 symmetrically arranged on the left and right sides of the first lower clamping plate assembly 22. The piston rod of the first gripper cylinder assembly 26 is perpendicular to the conveying direction of the wing flat tube, and a locking block 27 is fixedly connected to its end. When the wing flat tube enters the guide channel, the first gripper cylinder assemblies 26 on both sides synchronously drive the piston rod to extend, causing the locking block 27 to move towards the side where the wing flat tube is located, until the locking block 27 presses against the left and right sides of the wing flat tube, thereby achieving clamping and positioning of the wing flat tube.

[0081] The clamping device also includes a clamping cylinder mounting bracket 13 for supporting the first clamping cylinder assembly 26. This clamping cylinder mounting bracket 13 can reciprocate linearly along the conveying direction of the wing-shaped flat tube under the drive mechanism, thereby dragging the clamped wing-shaped flat tube to achieve continuous feeding. Furthermore, one side of the cylinder mounting bracket is provided with a mounting plate for fixing the cable chain, so as to accommodate the air pipe connected to the first clamping cylinder assembly 26, preventing the air pipe from becoming entangled or worn during movement, and ensuring the stability and safety of the equipment operation.

[0082] In some specific embodiments, such as Figures 6-8 As shown, the cutting tooth cutting mechanism includes a front fixed plate 6, a rear fixed plate 7, a cutting tooth assembly 3, a cutting assembly 4, and a combined drive assembly. The front fixed plate 6 and the rear fixed plate 7 are respectively disposed at the inlet and outlet ends of the mechanism. Both are arranged perpendicular to the conveying direction of the wing-shaped flat tube and are fixedly connected by left and right crossbeams 8 parallel to the wing-shaped flat tube to form a stable support frame. The front fixed plate 6 serves as the connecting component between the cutting tooth assembly 3 and the feeding mechanism 2, and its plate body has an inlet channel 61 for the wing-shaped flat tube to enter. The rear fixed plate 7 is disposed on the outlet side corresponding to the cutting assembly 4, and its plate has an outlet channel corresponding to the inlet channel 61.

[0083] The entrance channel 61 has a photoelectric sensor with a emitter and a receiver on opposite sides, which together form a through-beam photoelectric sensor to detect whether the flying wing tube has reached the entrance channel 61. A first vertical cylinder 62 is fixedly installed on the top of the front fixing plate 6, and the piston rod end of the first vertical cylinder 62 is connected to a liftable first baffle plate 63; when the first baffle plate 63 falls to the blocking position, it can block the entrance channel 61.

[0084] Based on the above structure, the inlet channel 61 serves as the positioning starting point for the wing-shaped flat tube to enter the tooth-cutting process. This facilitates the control system in calculating the forward length of the wing-shaped flat tube based on the feedback signal from the photoelectric sensor, thereby precisely controlling the cutting timing. The workflow is as follows: Initially, the first photoelectric sensor does not detect material. The first vertical cylinder 62 pushes the first baffle plate 63 downwards, closing the inlet channel 61. The operator pushes the wing-shaped flat tube through the flared inlet 23 into the first baffle plate 63. At this time, the wing-shaped flat tube physically blocks the light path of the first photoelectric sensor. After receiving the light path blocking signal, the system confirms that the wing-shaped flat tube has reached the preset positioning starting point, completing the feeding and positioning. Subsequently, the control system controls the first vertical cylinder 62 to retract, lifting the first baffle plate 63, allowing the wing-shaped flat tube to enter the subsequent tooth-cutting process.

[0085] like Figure 7 As shown, the cutting assembly 3 is used to cut off the excess portion of the wings on both sides of the wing tube. It includes a first support frame 31, on which vertically arranged first guide rails 32 are fixedly installed on opposite sides. First sliders 33 are slidably fitted on each first guide rail 32. A cutter holder 34 is fixedly connected between two first sliders 33. Cutting blades 35 corresponding to the wings on both sides of the wing tube are mounted on the bottom of the cutter holder 34. A drive assembly is provided above the cutter holder 34. Specifically, a first motor base 36 and a first motor 37 are fixed on the first support frame 31. The output shaft of the first motor 37 is connected to a vertically arranged first lead screw 38 via a coupling. A first lead screw nut 39 is threaded onto the first lead screw 38 and is fixedly connected to the top of the cutter holder 34. Thus, when the first motor 37 rotates, it can drive the cutter holder 34 and the cutting blades 35 to move smoothly up and down in the vertical direction via the lead screw and nut pair.

[0086] The guide channel corresponding to the cutting tooth assembly 3 includes a second upper clamping plate assembly 310 and a second lower clamping plate assembly 311. To ensure the stability of the flying wing flat tube position during the cutting process, pressure cylinders 312 are fixedly installed at both ends of the first support frame 31. The piston rod ends of each pressure cylinder 312 are fixedly connected to the ends of the second upper clamping plate assembly 310. When the two pressure cylinders 312 press down synchronously, the second upper clamping plate assembly 310 can be driven to move down to reliably press the top of the flying wing flat tube.

[0087] The cutting action is as follows: Initially, the cutter 35 is in the upper standby position, with its bottom higher than the upper slot. After the wing tube is positioned and clamped, the first motor 37 starts, driving the first lead screw 38 to rotate, which in turn drives the cutter holder 34 and the cutter 35 to move smoothly downwards, cutting the wings on both sides of the wing tube. The cutting stroke must ensure that the bottom of the cutter 35 is a certain distance lower than the bottom of the lower slot to ensure that the wing material is completely cut off. After cutting, the cutter 35 returns to its original position.

[0088] In addition, a first cover is provided on the outer side of the first support frame 31 to prevent debris from splashing during the cutting process. A first chip removal hole is provided on the work surface 1 at the position corresponding to the cutting area. A first guide plate 14 is provided on the front and rear sides below the first chip removal hole. The bottoms of the two first guide plates 14 are close to each other to form a converging structure, thereby concentrating and guiding the waste chips into the waste collection box below.

[0089] like Figure 7 As shown, the cutting assembly 4 is used to cut the long, serrated wing-shaped flat tube into several wing-shaped flat tube units of a preset length. Specifically, the cutting assembly 4 includes a second support frame 41 integrally connected to the first support frame 31. A pair of vertical second guide rails 42 are fixedly installed on the side wall of the second support frame 41. Second sliders 43 are slidably fitted on the second guide rails 42. A side plate 44 is connected between the two second sliders 43. A second motor base 45 and a second motor 46 are provided on the top of the second support frame 41. The output shaft of the second motor 46 is connected to a second lead screw 47 through a coupling. A second lead screw nut 48 is threaded onto the second lead screw 47. One side of the second lead screw nut 48 is fixedly connected to the side plate 44, thereby achieving stable vertical guidance. A sawing motor 49 is fixedly connected to the bottom of the second lead screw nut 48. A saw blade 410 is installed at the end of the output shaft of the sawing motor 49 for vertically cutting the wing-shaped flat tube. When the second motor 46 drives the second lead screw 47 to rotate, the second lead screw nut 48 drives the sawing motor 49 and the saw blade 410 to move downward along the second guide rail 42 to achieve the cutting action.

[0090] The saw blade 410 is equipped with a second cover on its outer side to prevent chips from flying. The work surface 1 corresponding to the cutting area is also equipped with a second chip drop hole, and a second guide plate 15 is provided at the bottom to guide the saw chips to fall. Larger curled chips generated by the cutting teeth and sawing debris are recycled separately for easy disposal as high-value waste.

[0091] To achieve continuous and efficient processing, the cutting assembly 3 and the cutting assembly 4 are fixedly connected by the connecting plate 9, forming a single module that can move synchronously back and forth in the horizontal direction. The cutting and cutting actions of this module are independent of each other and do not interfere with each other, and their respective vertical movements can be performed in parallel.

[0092] The outlet channel is equipped with a second photoelectric sensor to detect whether the flying wing flat tube has completely passed through the cut-off area.

[0093] A second gripper cylinder assembly 10 is provided between the cutting component 4 and the grinding mechanism 5. Its structure is the same as that of the first gripper cylinder assembly 26. The piston rod of this assembly is arranged perpendicular to the material guide channel, and its end is connected to a clamping block for clamping the cut-off wing flat tube unit.

[0094] To achieve uninterrupted material conveying, the tooth-cutting combined mechanism, the first gripper cylinder assembly 26, and the second gripper cylinder assembly 10 are driven collaboratively by an alternately operating first linkage drive mechanism 11 and a second linkage drive mechanism 12. The first linkage drive mechanism 11 drives the entire tooth-cutting combined mechanism to move horizontally, and includes a third motor 111 and a horizontal third lead screw 112 driven by it. The third lead screw 112 has two fourth sliders 113, which are fixedly connected to the outer covers of the tooth-cutting assembly and the cutting assembly, respectively. When the third motor 111 operates, it drives the third lead screw 112 to rotate, causing the fourth sliders 113 to move the entire tooth-cutting combined mechanism reciprocally along the conveying direction of the wing-shaped flat tube.

[0095] The second linkage drive mechanism 12 is used to drive the first gripper cylinder assembly 26 and the second gripper cylinder assembly 10 to move synchronously. It includes a smooth rod 121 and a fourth lead screw 122, with two double-hole sliders 123 connected horizontally between them. Each double-hole slider 123 includes a threaded hole and a smooth hole, wherein the threaded hole is threadedly engaged with the fourth lead screw 122, and the smooth hole is tightly engaged with the smooth rod 121. The fourth lead screw 122 passes through the front and rear fixed plates and is rotatably connected to them, and is driven to rotate by the fourth motor 124. The smooth rod 121 slides through the front and rear fixed plates, and its two ends are fixedly connected to the gripper cylinder mounting bracket 13 that supports the first gripper cylinder assembly 26 and the second gripper cylinder assembly 10, respectively. Its working principle is as follows: the fourth motor 124 drives the fourth lead screw 122 to rotate, which drives the double-hole slider 123 to move. Since the double-hole slider 123 is tightly fitted with the light rod 121, it pushes the light rod 121 and the gripper cylinder mounting brackets 13 at both ends to move synchronously, so as to achieve the consistency of the forward and backward movements of the first gripper cylinder assembly 26 and the second gripper cylinder assembly 10.

[0096] The above technical solution makes the conveying of the wing flat tube a continuous process: during the feeding stage, the first gripper cylinder assembly 26 clamps the wing flat tube and pushes it forward; when the front end of the wing flat tube enters the cutting station, the pressing cylinder 312 clamps it before the first gripper cylinder assembly 26 releases it, and pulls the product forward under the drive of the first linkage drive mechanism 11. At the same time, the first gripper cylinder assembly 26 retracts to its original position to prepare for the next push, which can ensure that the material is always in a controlled state of being clamped; when the cut wing flat tube reaches the second gripper cylinder assembly 10, it is clamped by the second gripper cylinder assembly 10 and moves forward synchronously with the first gripper cylinder assembly 26.

[0097] To ensure the smooth reciprocating movement of the cutting tooth cutting mechanism in the horizontal direction, horizontal guide rail pairs 16 are arranged on the crossbeams 8 on both the left and right sides.

[0098] This assembly also includes a controller, which is electrically connected to the aforementioned motors, cylinders, and sensors to execute preset automated processing programs. To address the issues of precise initial cutting and handling of long material tails, the controller incorporates specific control logic: setting the target cutting length as L... cut The single feed distance of the first and second linkage drive mechanisms is L. step The length of the cutter is M and satisfies M > 2L. step To ensure that the cutting area is completely covered during the round trip; the horizontal distance from the positioning starting point of the entrance channel 61 (i.e. the detection position of the first photoelectric sensor) to the original position of the saw blade 410 (the position before the cutting component 4 moves back and forth) is a fixed value N.

[0099] The core algorithm of the controller is as follows:

[0100] S1. Start-up and initial feed: After startup, the first gripper cylinder assembly 26 clamps the wing flat tube and begins to convey it forward under the action of the second linkage drive mechanism 11; when the wing flat tube reaches the inlet channel and is identified by the first photoelectric sensor, it serves as the positioning starting point, and the first baffle plate 63 is lifted by external control.

[0101] S2. When the first gripper cylinder assembly 26 drives the wing flat tube to move forward L from the positioning starting point... step And stop, before it releases the winged flat tube, the pressure cylinder 312 presses down to fix the workpiece position, the first gripper cylinder assembly 26 releases the workpiece and retracts, and at the same time the first linkage drive mechanism drives the workpiece to continue moving forward L step Thus, the first and second linkage drive mechanisms operate alternately, with the workpiece moving forward 2L in each cycle. step During the forward movement of the first linkage drive mechanism, the cutting tooth assembly 3 cuts the excess wing portion on both sides of the flying wing flat tube; after the cutting is completed, the cutter 35 resets; thus realizing continuous cutting operation while moving and cutting.

[0102] S3. Subsequently, the wing-shaped flat tube continues to be conveyed forward; when the front end of the wing-shaped flat tube reaches the cutting station, the control system begins to cut according to the preset target length L. cut And calculate the initial feed distance S1 at a fixed distance N, S1 = L cut + N, after the first and second linkage drive mechanisms complete m alternating cycles, the length of the wing flat tube delivered downstream of the saw blade reaches L. cut L cut =m×2L step At this point, the cutting component 4 starts working and performs the first cutting of the flying wing flat tube in the follow-up state;

[0103] S4. After the initial cut, the new front end of the wing-shaped flat tube is located at the bottom of the saw blade; thereafter, simply control the wing-shaped flat tube to precisely feed it forward L. cut The controller synchronously records the number of reciprocating cycles of the cutting mechanism, and a cut is completed when a predetermined number of cycles m is reached; for example, when L... cut =1000mm, L step When =100mm, each L is conveyed cut The length requires the first and second linkage drive mechanisms to reciprocate 5 cycles.

[0104] S5. When the first photoelectric sensor detects that no new material is entering, the system enters the material tail processing mode and continues to execute the cut-off until the second photoelectric sensor detects that there is no material at the outlet. The last section of the flying wing flat tube of the workpiece is cut off and discharged. When the next workpiece enters the feeding mechanism 2 and triggers the first photoelectric sensor again, the system automatically repeats the above process.

[0105] Through the above structural design and control methods, this assembly achieves continuous processing: Traditional cutting equipment requires pausing the feeding mechanism during fixed-length cutting, and then resuming feeding after the cutting is completed, resulting in interruption of production cycle and affecting overall efficiency. However, this assembly integrates the cutting tooth assembly 3 and the cutting assembly 4 into a horizontally reciprocating joint mechanism, and with the relay clamping and synchronous feeding of the first gripper cylinder assembly 26 and the second gripper cylinder assembly 10, the saw blade 410 can move forward synchronously with the flying wing flat tube during the cutting process, thereby completing the cutting action without interrupting the feeding, and achieving true continuous production.

[0106] This assembly employs a continuous feed and follow-up cutting processing method, which significantly reduces the length of raw materials for wing-shaped flat tubes. Traditional equipment requires stopping the machine for cutting, typically requiring raw material lengths of over 5 meters to ensure processing continuity. However, this assembly, through the coordinated movement of the cutting tooth cutting mechanism and the gripper cylinder assembly, achieves a "cutting while moving" follow-up cutting function, completing the cutting operation without stopping the machine. Therefore, only short materials of about 2 meters are needed for continuous production, greatly reducing the length requirements of raw materials and thus significantly reducing material procurement and storage costs.

[0107] In some specific embodiments, such as Figure 8 As shown, the grinding mechanism 5 is located on the exit side of the tooth cutting joint mechanism and is used to deburr the end and both sides of the wing flat tube after tooth cutting and fixed-length cutting. The grinding mechanism 5 includes an upper grinding component 51 and a lower grinding component 52, which work together to clean the wing surfaces on the upper and lower sides of the wing flat tube to remove burrs, flash, and residual metal chips generated during processing, ensuring the surface finish and assembly accuracy of the finished product.

[0108] The upper grinding assembly 51 includes two upper grinding motors and upper wire wheels driven by them, with the two upper grinding motors symmetrically arranged on the left and right sides of the material guide channel. Each upper wire wheel has a steel brush embedded in its circumferential surface for rotating and grinding the upper surface area of ​​the toothed surfaces on both sides of the wing-shaped flat tube after cutting. The lower grinding assembly 52 includes two lower grinding motors and lower wire wheels driven by them, with the two lower grinding motors also symmetrically arranged on the left and right sides of the material guide channel. The steel brushes on the wire wheels grind and clean the lower surface area of ​​the toothed surfaces on both sides of the wing-shaped flat tube. In the vertical direction, the upper grinding assembly 51 and the lower grinding assembly 52 are staggered to correspond to and cover the grinding area of ​​the wing-shaped flat tube.

[0109] Considering that during the tooth cutting process, when the cutter 35 cuts the wing from top to bottom, it will carry some burrs and metal residue downwards, causing the burrs on the lower surface of the wing-shaped flat tube to extend downwards. To effectively remove these burrs, the grinding mechanism 5 has been specifically designed with the rotation direction of the wire wheels in mind: the two upper wire wheels rotate in opposite directions, their rotation direction being in line with the extension direction of the burrs, that is, the tangential movement direction on the upper surface of the wing-shaped flat tube is downwards, so as to achieve forward removal of burrs; the two lower wire wheels rotate in opposite directions, that is, the tangential movement direction on the lower surface of the wing-shaped flat tube is upwards, thereby forming a reverse cutting of the burrs on the lower surface, enhancing the grinding effect, and ensuring that the burrs are completely removed.

[0110] To enable adaptable processing of wing-shaped flat tubes of different heights, the upper grinding assembly 51 is configured with a height-adjustable structure. Specifically, a suspended first support plate 511 is provided at the bottom of the guide channel corresponding to the grinding mechanism 5. Two upper grinding motors are respectively installed at the top of both ends of the first support plate 511. A support frame 512 is connected to the bottom of the first support plate 511 and is fixed to the worktable 1. A second waist hole extending vertically is provided on the support frame 512. The side of the first support plate 511 is fixedly connected to the support frame 512 by bolts passing through the second waist hole. By adjusting the fixing position of the bolts in the second waist hole, the overall height of the first support plate 511 and the upper grinding assembly 51 can be adjusted to accommodate wing-shaped flat tubes of different heights. The support frame 512 is preferably an L-shaped structure, with its bottom surface fixedly connected to the worktable 1 by bolts, and its side surface connected to the first support plate 511 through the second waist hole, resulting in a compact structure and convenient adjustment.

[0111] Furthermore, to accommodate winged flat tubes of varying thicknesses (i.e., the distance between the left and right wings), the spacing between the two upper grinding motors in the upper grinding assembly 51 is also adjustable. Specifically, the first support plate 511 has horizontally extending third waist holes at both ends, the length of which is perpendicular to the conveying direction of the material guide channel. The upper grinding motors are fixedly connected to the first support plate 511 via bolts passing through the third waist holes. By adjusting the fixing position of the bolts within the third waist holes, the relative spacing between the two upper grinding motors can be changed, thereby ensuring that the wire wheel always maintains good contact with the upper surfaces on both sides of the winged flat tube. When the grinding radius decreases due to wear of the upper wire wheel, the position of the motors can be adjusted downwards as a whole to ensure that the upper wire wheel always effectively contacts the workpiece.

[0112] The height of the lower grinding assembly 52 is relatively fixed and does not require adjustment, but the distance between its two lower grinding motors is also adjustable to accommodate workpieces of different thicknesses. Specifically, a second support plate 521 is provided below the grinding mechanism 5. The second support plate 521 has a fourth waist hole extending horizontally, and the length direction of the fourth waist hole is also perpendicular to the conveying direction of the guide channel. The two lower grinding motors are fixedly connected to the second support plate 521 by bolts passing through the fourth waist hole. By adjusting the fixed position of the bolts in the fourth waist hole, the distance between the two lower grinding motors can be flexibly adjusted to ensure that the lower wire wheel can accurately fit against the lower surface of both sides of the wing flat tube for effective grinding.

[0113] Preferably, the upper and lower wire wheels are enclosed by a cover; the worktable 1 is provided with chip removal holes corresponding to the grinding area, and the fine dust generated during grinding is collected through a dedicated channel.

[0114] Through the above structural design, the grinding mechanism 5 not only achieves directional and efficient deburring of the upper and lower surfaces of the wing-shaped flat tube, but also significantly improves the versatility and processing adaptability of the equipment through multi-dimensional adjustment functions, which can meet the grinding needs of workpieces of different specifications and further ensure the stability of finished product quality.

[0115] In terms of working environment and cleanliness, this assembly effectively controls metal shavings, dust and other pollutants generated during cutting, sawing and grinding within the processing area by setting up fully enclosed or semi-enclosed protective covers in each processing area. This avoids the pollution of the workshop environment by flying debris, significantly improves the cleanliness of the work site, and meets the requirements of modern green manufacturing and clean production.

[0116] The working method for the wing-shaped flat tube cutting and grinding assembly proposed in this application is as follows:

[0117] S1. The wing flat tube to be processed is introduced into the feeding mechanism 2 through the horn-shaped inlet 23, and moves along the guide channel under the clamping and pushing of the first gripper cylinder assembly 26 until it touches the first baffle plate 63.

[0118] S2. After the first baffle plate 63 is lifted, the flying wing flat tube enters the tooth cutting process; the first and second linkage drive mechanisms 11 operate alternately, and the tooth cutting and cutting joint mechanism moves horizontally forward and then moves vertically; the tooth cutting assembly and the cutting assembly move horizontally in sync and do not interfere with each other in vertical operation.

[0119] S3. The cut-off wing flat tube unit enters the grinding mechanism 5, where the upper grinding component 51 and the lower grinding component 52 respectively rotate and brush its upper and lower surfaces to remove burrs and flash from the end face and both sides, finally obtaining the finished product.

[0120] The entire processing is automated through a controller that controls each motor, cylinder, and sensor, enabling integrated continuous production of feeding, tooth cutting, fixed-length cutting, and deburring.

[0121] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
