Description

Technical Field

[0001] This invention relates to the field of coil spring processing equipment technology, specifically to a coil spring deburring and winding equipment and its processing method. Background Technology

[0002] After the initial processes such as slitting and stamping, sharp burrs will be generated on both sides of the coiled spring sheet. These burrs not only affect the appearance and safety of the product, but may also cause damage or affect assembly during use. Therefore, removing the burrs on both sides of the coiled spring sheet is a key step in its finishing process.

[0003] Currently, traditional deburring equipment mostly adopts a linear "through" layout, where the unwinding unit and the rewinding unit are fixed at opposite ends of the equipment's length. This layout requires operators to repeatedly travel between the two sides of the equipment during a complete production cycle: first, loading and threading the tape on one side, then unloading on the other side after processing, and finally returning to the starting side to load the next roll. This layout generates a significant amount of non-value-adding walking and waiting time, resulting in high labor intensity for personnel. Production efficiency is limited by the operator's movement speed, making it difficult to achieve efficient single-person operation and hindering seamless integration with automated logistics systems. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a deburring and winding device for coiled springs and its processing method.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: An adaptive speed-controlled spring deburring and winding device includes a deburring component and a winding / unwinding component. The take-up and unwinding assembly includes a first take-up and unwinding unit and a second take-up and unwinding unit respectively disposed on both sides of the burr removal assembly; The burr removal assembly includes a machine base, a burr removal structure and a tension roller assembly mounted on the machine base; The machine is equipped with a first burr collection frame and a second burr collection frame. The first burr collection frame and the second burr collection frame are respectively located on both sides of the burr removal structure. The burr removal structure includes a mounting plate, a rotating unit mounted on the mounting plate, a mounting seat mounted on the moving end of the rotating unit, two burr removal scrapers mounted on the mounting seat, and a rotating unit that drives the mounting plate to rotate. The burr removal scrapers form a burr removal channel for scraping burrs off the coiled spring sheet. The burr removal structure has a first deburring state and a second deburring state. When the burr removal structure is in the first deburring state, the input end of the burr removal channel is oriented towards the first take-up and untake-up unit, and the rotating unit drives the mounting plate to rotate so that the mounting plate is tilted towards the first burr recovery frame. When the burr removal structure is in the second deburring state, the rotating unit drives the mounting base to rotate so that the input end of the burr removal channel is oriented towards the second take-up and untake-up unit, and the rotating unit drives the mounting plate to rotate so that the mounting plate is tilted towards the second burr recovery frame.

[0006] Preferably, the mounting base is provided with a burr guide plate, which is positioned towards the first burr recovery frame or the second burr recovery frame. The burr guide plate has an arc-shaped material discharge slope. Through the above improvements, the burrs generated during the grinding process can slide into the designated recovery frame more smoothly and quickly by the guidance of the arc-shaped material discharge slope. This effectively avoids the splashing, retention or secondary adhesion of burrs inside the equipment, significantly improving cleaning efficiency and recovery rate. In addition, this structure reduces the frequency of manual cleaning, ensuring the continuous cleanliness and operational safety of the grinding station.

[0007] Preferably, the first and second burr collection frames are equipped with burr winding rollers, and the burr winding rollers have a plurality of winding protrusions. Through the above improvements, by setting burr winding rollers with winding protrusions, efficient classification and processing of strip-shaped and clump-shaped burrs generated by grinding is achieved. During equipment operation, longer strip-shaped burrs are first captured by the rotating winding protrusions and automatically wrapped and collected, avoiding them from wrapping around the moving parts of the equipment or blocking the collection channel; while shorter fragment burrs are unaffected and slide directly down the guide plate to the bottom of the collection frame, significantly improving the separation and recycling capacity of metal waste of different shapes, reducing the risk of equipment jamming, ensuring smooth and stable continuous operation, and simplifying the subsequent burr classification and processing process.

[0008] Preferably, the machine platform is provided with a burr discharge outlet, which is connected to a first burr collection frame and a second burr collection frame. A lifting plate is movably arranged at the bottom of the first and second burr collection frames, and a pusher block is movably arranged inside the first and second burr collection frames. The pusher block slides toward the burr discharge outlet and pushes the burrs out of the burr discharge outlet. The pusher block has a relief groove for the winding protrusion to be placed. Through the above improvements, the lifting plate and the pusher block cooperate to realize fully automatic and batch cleaning of burrs from collection to discharge. During the burr discharge process, the lifting plate is first raised, and then the pusher block moves horizontally. Its relief groove accurately avoids the rotating winding protrusion, pushing all the burrs out of the discharge outlet at once. This structure completely avoids the downtime and safety hazards caused by manual cleaning, realizes the combined discharge of burrs of different shapes, and greatly improves the continuous operation time of the equipment and the overall maintenance efficiency.

[0009] Preferably, a clamping plate is provided above the first and second burr collection frames. The clamping plate is equipped with an elastic element connected to the machine base, ensuring that the clamping plate always tends to move away from the first or second burr collection frame. A driving protrusion is provided on the lifting plate. When the lifting plate rises, the driving protrusion drives the clamping plate to rotate, so that the clamping plate is horizontally positioned above the first or second burr collection frame. Through this improvement, when the lifting plate rises to execute the discharge procedure, the driving protrusion simultaneously forces the clamping plate to press down horizontally, instantly compacting and fixing the loose burrs in the collection frames, especially the coiled long strips of burrs. This effectively prevents them from scattering, rebounding, or tangling during the material pushing process, ensuring smooth and thorough discharge, increasing the burr processing capacity per discharge, and avoiding the risk of blockage caused by loose burrs, making the automated cleaning process more reliable and efficient.

[0010] Preferably, the mounting base is provided with an adjusting screw, which includes a first threaded section and a second threaded section. A first sliding block is provided on the first threaded section, and a second sliding block is provided on the second threaded section. The deburring scraper is disposed on the first and second sliding blocks. The adjusting screw rotates to bring the first and second sliding blocks closer together or further apart. Through the above improvements, precise and rapid adjustment of the distance between the two deburring scrapers is achieved. By rotating a single adjusting screw, the first and second sliding blocks can be driven to move synchronously, thereby ensuring that the two scrapers always move symmetrically with the center of the mounting base as a reference, and ensuring that the pressure of the scrapers acting on both sides of the coil spring is uniform and consistent. This effectively avoids the problem of coil spring deformation or incomplete deburring on one side due to uneven force, and significantly improves the stability of deburring quality and equipment adjustment efficiency.

[0011] Preferably, the burr removal structure is provided with guide limiting structures on both sides. The guide limiting structure includes a guide limiting seat, a limiting block slidably disposed on the guide limiting seat, and an adjustment unit for driving the limiting block to slide up and down. The guide limiting seat and the limiting block form a limiting groove for inserting the coiled spring sheet. Through the above improvements, the adjustable limiting block and the guide limiting seat form an adaptive limiting groove, which can accurately guide coiled spring sheets of different thicknesses or widths to pass smoothly through the burr removal station along a preset path. This effectively prevents the coiled spring sheet from swaying, jumping, or longitudinally displacing during the scraping process, ensuring the uniformity and consistency of burr removal, and significantly improving the equipment's compatibility and processing stability for products of different specifications.

[0012] Preferably, the tensioning roller assembly includes a tensioning bracket disposed on the spring conveying path, an adjusting block slidably disposed on the tensioning bracket, and a tensioning roller disposed on the adjusting block. The tensioning bracket is provided with a height adjustment groove for the adjusting block to slide up and down. With the above improvements, by adjusting the position of the adjusting block in the height adjustment groove, the wrap angle and tension of the spring can be quickly changed, thereby ensuring that the spring maintains appropriate tension during transmission and deburring.

[0013] Preferably, the machine platform is also provided with a guide frame, which is located above the first burr collection frame and the second burr collection frame, and is flared towards the burr removal scraper. Through the above improvements, the flared shape significantly increases the effective receiving area, ensuring that no matter which angle the burrs break out from, they can be caught by the guide frame and guided into the collection frame below. This greatly reduces the risk of burrs falling outside the equipment or onto key moving parts, ensures a clean working environment, reduces the equipment failure rate, and makes burr collection more concentrated and thorough.

[0014] A processing method for a deburring device includes the following steps: S1 Loading and Threading: Load a coil of spring material to be processed into the first take-up and unwinding unit, set the burr removal structure to the first deburring state, pass the spring sheet through the tension roller group and the burr removal channel of the burr removal assembly in sequence, and fix the spring sheet head to the second take-up and unwinding unit. S2 Burr Removal: Start the equipment, the first unwinding unit unwinds, the second unwinding unit winds, and the coil spring is continuously conveyed in a single direction. When the coil spring passes through the burr removal channel, the burrs on both sides of the coil spring are scraped off, causing the burrs to fall into the first burr recycling box. S3 Single-sided unloading and reloading: The processed coil spring material is removed from the second take-up and unwinding unit, a coil spring material to be processed is loaded into the second take-up and unwinding unit, the burr removal structure is adjusted to the second deburring state, and the spring sheet head is fixed to the first take-up and unwinding unit. S4 Burr Removal: The second unwinding unit unwinds the coil, and the first unwinding unit winds it up. The coil spring is continuously conveyed in a single direction. When the coil spring passes through the burr removal channel, the burrs on both sides of the coil spring are scraped off, causing the burrs to fall into the second burr collection box. Step S1 is repeated to start the next cycle.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: When the first unwinding unit unwinds and the second unwinding unit winds up, and the burr removal structure is in the first deburring state, the mounting plate is tilted towards the first recycling frame to scrape off the forward conveying coil spring sheet, and removes and directionally collects the burrs on both sides. The burrs will fall into the tilted area of ​​the first recycling frame. After processing one coil spring sheet, the burr removal structure switches to the second deburring state, removes the processed coil spring sheet from the second unwinding unit, and loads a new coil spring sheet onto the second unwinding unit. The second unwinding unit then performs... Unwinding: The first unwinding unit rewinds the coil, and the mounting plate tilts towards the second burr collection frame. During reverse conveying, another round of deburring of the coiled spring is completed. The burrs fall into the tilted area of ​​the second burr collection frame. After the first feeding and threading is completed, all subsequent feeding and unloading actions are concentrated on the same operating side of the equipment. Operators do not need to travel back and forth between the two ends of the equipment. Compared with existing technologies, production efficiency is greatly improved. The single-sided operating layout reduces the time for personnel to travel back and forth. Furthermore, the first and second burr collection frames rotate in conjunction with the burr removal structure to ensure the collection effect of burrs and improve the cleanliness of the processing environment.

Detailed Implementation

[0017] 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.

[0018] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-11 As shown, a spring deburring and winding device includes a deburring component 1 and a winding and unwinding component 2.

[0020] Specifically, the take-up and unwinding assembly 2 includes a first take-up and unwinding unit 1.1 and a second take-up and unwinding unit 1.2 respectively disposed on both sides of the burr removal assembly 1 for taking up and unwinding the spring sheets. The burr removal assembly 1 includes a machine base 1.3, a burr removal structure 1.4 disposed on the machine base 1.3 and a tension roller group 1.5.

[0021] Furthermore, the machine 1.3 is equipped with a first burr collection frame 2.1 and a second burr collection frame 2.2. The first burr collection frame 2.1 and the second burr collection frame 2.2 are respectively located on both sides of the burr removal structure 1.4. The burr removal structure 1.4 includes a mounting plate 3.1, a rotating unit 3.2 mounted on the mounting plate 3.1, a mounting seat 3.3 mounted on the moving end of the rotating unit 3.2, two burr removal scrapers 3.4 mounted on the mounting seat 3.3, and a rotating unit 3.5 that drives the mounting plate 3.1 to rotate. The burr removal scrapers 3.4 form a burr removal channel 3.6 for scraping burrs from the coiled spring sheet. The rotating unit 3.2 can drive the mounting plate 3.1 to swing left and right, and the rotating unit 3.2 can drive the mounting seat 3.3 to rotate horizontally.

[0022] The burr removal structure 1.4 has a first deburring state and a second deburring state. When the burr removal structure 1.4 is in the first deburring state, the input end of the burr removal channel 3.6 is oriented towards the first take-up and unwinding unit 1.1, and the rotating unit 3.5 drives the mounting plate 3.1 to rotate so that the mounting plate 3.1 is tilted towards the first burr recovery frame 2.1. When the burr removal structure 1.4 is in the second deburring state, the rotating unit 3.2 drives the mounting base 3.3 to rotate so that the input end of the burr removal channel 3.6 is oriented towards the second take-up and unwinding unit 1.2, and the rotating unit 3.5 drives the mounting plate 3.1 to rotate so that the mounting plate 3.1 is tilted towards the second burr recovery frame 2.2.

[0023] In the entire deburring process, the unprocessed coiled spring sheet is first placed on the first take-up and unwinding unit 1.1. After the coiled spring sheet is threaded, the first take-up and unwinding unit 1.1 unwinds, and the second take-up and unwinding unit 1.2 winds it up. The deburring structure 1.4 is in the first deburring state, with the mounting plate 3.1 tilted towards the first recycling frame to scrape off the forward-conveyed coiled spring sheet. The deburring structure 1.4 removes burrs from both sides of the coiled spring sheet and achieves directional collection, causing the burrs to fall into the first burr recycling frame 2.1. After processing one coiled spring sheet, the processed coiled spring sheet is removed from the second take-up and unwinding unit 1.2, and an unprocessed coiled spring sheet is installed on the second take-up and unwinding unit 1.2. The deburring structure 1.4 is then in the first deburring state. .4 Switch to the second deburring state to thread the coiled spring sheets. The second unwinding unit 1.2 unwinds the spring sheets, and the first unwinding unit 1.1 winds them up. The mounting plate 3.1 tilts towards the second deburring collection frame 2.2. Another round of deburring of the coiled spring sheets is completed in the reverse conveying. After the first feeding and threading is completed, all subsequent feeding and unloading actions are concentrated on the same operating side of the equipment. Operators do not need to travel back and forth between the two ends of the equipment. Compared with the existing technology, the production efficiency is greatly improved. The single-sided operation layout reduces the time for personnel to travel back and forth. In addition, the first deburring collection frame 2.1 and the second deburring collection frame 2.2 rotate in conjunction with the deburring removal structure 1.4 to ensure the collection effect of burrs and improve the cleanliness of the processing environment.

[0024] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, to further explain the embodiment of the burr removal structure 1.4, the mounting base 3.3 is provided with an adjusting screw 6.3, which includes a first threaded section 6.4 and a second threaded section 6.5. The threads of the first threaded section 6.4 and the second threaded section 6.5 are set in opposite directions. A first sliding block is provided on the first threaded section 6.4, and a second sliding block is provided on the second threaded section 6.5. The burr removal scraper 3.4 is set on the first sliding block and the second sliding block. The adjusting screw 6.3 is rotated to make the first sliding block and the second sliding block move closer or further apart. The rotation can achieve precise and rapid adjustment of the distance between the two burr removal scrapers 3.4, thereby ensuring that the two scrapers always move symmetrically with the center of the mounting base 3.3 as the reference, and ensuring that the pressure of the scraper on both sides of the coil spring is uniform. This effectively avoids the problem of coil spring deformation or incomplete burr removal on one side due to uneven force, and significantly improves the stability of deburring quality and equipment adjustment efficiency.

[0025] The adjusting screw 6.3 is connected to an adjusting handle 6.8 at its end. The adjusting handle 6.8 can be rotated to quickly adjust the size of the burr removal channel 3.6.

[0026] In addition, the mounting base 3.3 is also equipped with guide rollers 9.4, which are set on the conveying path of the coiled spring and support the bottom of the coiled spring, thereby improving the smoothness of the coiled spring conveying.

[0027] Specifically, a burr guide plate 4.1 is provided on the mounting base 3.3. The burr guide plate 4.1 is positioned facing the first burr recovery frame 2.1 or the second burr recovery frame 2.2, and the burr guide plate 4.1 has an arc-shaped material dropping slope 4.4. Through the guidance of the arc-shaped material dropping slope 4.4, the burrs generated during the grinding process can slide into the designated recovery frame more smoothly and quickly, effectively avoiding the splashing, retention or secondary adhesion of burrs inside the equipment, significantly improving cleaning efficiency and recovery rate. In addition, this structure reduces the frequency of manual cleaning, ensuring the continuous cleanliness and operational safety of the grinding station.

[0028] Preferably, an air blowing pipe 9.3 is inserted into the burr guide plate 4.1, with the output end of the air blowing pipe 9.3 facing the direction of burr falling, to prevent burrs from clogging inside the burr guide plate 4.1 and to further improve the smoothness of burr falling.

[0029] like Figure 1 , Figure 3 , Figure 6 As shown, a further explanation of the implementation of the first burr recovery frame 2.1 and the second burr recovery frame 2.2 in this embodiment is provided. A burr winding roller 4.2 is rotated inside the first burr recovery frame 2.1 and the second burr recovery frame 2.2, and the burr winding roller 4.2 has several winding protrusions 4.3. By setting the burr winding roller 4.2 with winding protrusions 4.3, efficient classification and processing of strip-shaped and clump-shaped burrs generated by grinding is achieved. During equipment operation, longer strip-shaped burrs are first captured by the rotating winding protrusions 4.3 and automatically wound and collected, preventing them from entangled in moving parts of the equipment or blocking the recovery channel; while shorter fragment burrs are unaffected and slide directly down the guide plate to the bottom of the recovery frame, significantly improving the separation and recycling capacity of metal waste of different forms, reducing the risk of equipment jamming, ensuring smooth and stable continuous operation, and simplifying the subsequent burr classification and processing procedures.

[0030] The burr winding roller 4.2 is driven by a winding motor 4.5 to rotate slowly, and the burr winding roller 4.2 can be rotated intermittently according to the settings.

[0031] Specifically, the machine 1.3 has a burr outlet 5.1, which is connected to the first burr collection frame 2.1 and the second burr collection frame 2.2. A lifting plate 5.2 is movably installed at the bottom of both the first and second burr collection frames 2.1 and 2.2. A pusher block 5.3 is movably installed inside both frames, sliding towards the burr outlet 5.1 and pushing the burrs out of it. The pusher block 5.3 also has a clearance groove 5.4 for the winding protrusion 4.3 to be inserted. The cooperation between the lifting plate 5.2 and the pusher block 5.3 enables fully automated, batch cleaning of burrs from collection to discharge. During the burr discharge process, the lifting cylinder 5.6 first lifts the lifting plate 5.2, and then the pusher cylinder 5.7 drives the pusher block 5.3 to move horizontally. Its avoidance groove 5.4 precisely avoids the rotating coiled protrusion 4.3, pushing all the burrs out of the discharge port at once. This structure completely avoids the downtime and safety hazards caused by manual cleaning, realizes the combined discharge of burrs of different shapes, and greatly improves the continuous operation time of the equipment and the overall maintenance efficiency.

[0032] Furthermore, a clamping plate 6.1 is mounted above the first burr collection frame 2.1 and the second burr collection frame 2.2. An elastic element 6.2 is mounted on the clamping plate 6.1 and connected to the machine base 1.3, ensuring that the clamping plate 6.1 always tends to move away from either the first burr collection frame 2.1 or the second burr collection frame 2.2. A driving protrusion 5.5 is mounted on the lifting plate 5.2. When the lifting plate 5.2 rises, the driving protrusion 5.5 drives the clamping plate 6.1 to rotate, so that the clamping plate 6.1 is horizontally positioned above the first burr collection frame 2.1. Above frame 2.1 or the second burr recovery frame 2.2, when the lifting plate 5.2 rises to execute the material discharge procedure, the driving protrusion 5.5 simultaneously forces the clamping plate 6.1 to press down horizontally, instantly compacting and fixing the loose burrs in the recovery frame, especially the long strips that have been rolled up. This effectively prevents them from scattering, rebounding, or tangling during the material pushing process, ensuring smooth and thorough material discharge, increasing the amount of burrs processed in a single discharge, and avoiding the risk of blockage caused by loose burrs, making the automated cleaning process more reliable and efficient.

[0033] The clamping plate 6.1 is hinged to the top of the first burr collection frame 2.1 and the second burr collection frame 2.2, and the tail of the clamping plate 6.1 extends out of the first burr collection frame 2.1 and the second burr collection frame 2.2. The elastic element 6.2 is connected to the area near the top of the clamping plate 6.1, and the driving protrusion 5.5 abuts against the position where the tail of the clamping plate 6.1 extends out of the first burr collection frame 2.1 and the second burr collection frame 2.2, so that the clamping plate 6.1 rotates.

[0034] like Figure 10As shown, preferably, the burr outlet 5.1 is provided with a baffle plate 9.1. In the initial state, the baffle plate 9.1 blocks the burr outlet 5.1 to prevent burrs from being discharged during processing. When discharging, the pusher block 5.3 will drive the burrs to push open the baffle plate 9.1 to discharge the burrs.

[0035] like Figure 11 As shown, in some other embodiments, the lifting plate 5.2 includes a lifting plate 10.2 connected to the driving protrusion 5.5, and a support plate 10.1 slidably disposed on the lifting plate 10.2, and the burrs fall onto the support plate 10.1. The lifting plate 10.2 is provided with a plurality of pressure sensors 9.2, which can discharge the burrs according to their weight.

[0036] like Figure 2 , Figure 3 , Figure 6 As shown, preferably, the machine base 1.3 is also equipped with a guide frame 8.5. The guide frame 8.5 is located above the first burr collection frame 2.1 and the second burr collection frame 2.2, and it is flared towards the burr removal scraper 3.4. The flared shape significantly increases the effective receiving area, ensuring that no matter which angle the burrs break out from, they can be caught by the guide frame 8.5 and guided into the collection frame below. This greatly reduces the risk of burrs scattering onto the outside of the equipment or critical moving parts, ensures a clean working environment, reduces the equipment failure rate, and makes burr collection more concentrated and thorough.

[0037] like Figure 1 , Figure 9 As shown, as a further explanation of the specific structure of the first take-up and unwinding unit 1.1 and the second take-up and unwinding unit 1.2, it includes a take-up bracket 11.2, a take-up reel 11.1 mounted on the take-up bracket 11.2, and a take-up motor 11.3 that drives the take-up reel 11.1 to rotate. The spring sheet is set on the take-up reel 11.1, and the take-up motor 11.3 drives the take-up reel 11.1 to rotate, so as to realize the take-up and unwinding of the spring sheet.

[0038] like Figure 1 , Figure 2 , Figure 7As shown in the further explanation of the spring sheet conveying limit in this application, the burr removal structure 1.4 is provided with guide limiting structures 7.1 on both sides. The guide limiting structure 7.1 includes a guide limiting seat 7.2, a limiting block 7.3 slidably disposed on the guide limiting seat 7.2, and an adjustment unit 7.4 for driving the limiting block 7.3 to slide up and down. The guide limiting seat 7.2 and the limiting block 7.3 form a limiting groove 7.5 for the spring sheet to be placed. The adjustable limiting block 7.3 and the guide limiting seat 7.2 form an adaptive limiting groove 7.5, which can accurately guide spring sheets of different thicknesses or widths to pass smoothly through the burr removal station along a preset path. This effectively prevents the spring sheet from swaying, jumping or longitudinal displacement during the scraping process, ensuring the uniformity and consistency of burr removal, and significantly improving the equipment's compatibility and processing stability for products of different specifications.

[0039] Among them, the adjustment unit 7.4 is a cylinder with adjustable stroke, which can quickly adjust the size of the limit groove 7.5 as needed.

[0040] Furthermore, the tensioning roller assembly 1.5 includes a tensioning bracket 8.1 disposed on the spring conveying path, an adjusting block 8.2 slidably disposed on the tensioning bracket 8.1, and a tensioning roller 8.3 disposed on the adjusting block 8.2. The tensioning bracket 8.1 is provided with a height adjustment groove 8.4 for the adjusting block 8.2 to slide up and down. By adjusting the position of the adjusting block 8.2 in the height adjustment groove 8.4, the wrap angle and tension of the spring can be quickly changed, thereby ensuring that the spring maintains appropriate tension during transmission and deburring.

[0041] like Figures 1 to 11 As shown, a processing method for a burr winding device includes the following steps: S1 Loading and Threading: Load a roll of coil spring material to be processed into the first take-up and unwinding unit 1.1, set the burr removal structure 1.4 in the first deburring state, pass the coil spring sheet through the tension roller group 1.5 and the burr removal channel 3.6 of the burr removal assembly 1 in sequence, and fix the head of the coil spring sheet to the second take-up and unwinding unit 1.2. S2 Burr Removal: Start the equipment, the first unwinding unit 1.1 unwinds, the second unwinding unit 1.2 winds up, and the coil spring is continuously conveyed in a single direction. When the coil spring passes through the burr removal channel 3.6, the burrs on both sides of the coil spring are scraped off, causing the burrs to fall into the first burr recovery box 2.1. S3 Single-sided unloading and reloading: The processed coil spring material is removed from the second take-up and unwinding unit 1.2, a coil spring material to be processed is loaded into the second take-up and unwinding unit 1.2, the burr removal structure 1.4 is adjusted to the second deburring state, and the head of the coil spring sheet is fixed to the first take-up and unwinding unit 1.1. S4 Burr Removal: The second unwinding unit 1.2 unwinds the coil, and the first unwinding unit 1.1 winds it up. The coil spring is continuously conveyed in a single direction. When the coil spring passes through the burr removal channel 3.6, the burrs on both sides of the coil spring are scraped off, causing the burrs to fall into the second burr collection box 2.2. Step S1 is repeated to start the next cycle.

[0042] The process after S2 includes burr recovery. The scraped burrs are first guided by the inclined burr guide plate 4.1 and its arc-shaped discharge slope 4.4 into the first burr recovery frame 2.1 or the second burr recovery frame 2.2 on the corresponding working side. In the recovery frame, the rotating burr winding roller 4.2 and its winding protrusion 4.3 actively wind and collect the loose burrs. When cleaning is required, the lifting plate 5.2 at the bottom of the recovery frame rises, and at the same time, the pusher block 5.3 in the frame (with its avoidance groove 5.4 to avoid the winding protrusion 4.3) pushes the burrs toward the burr discharge port 5.1 and out of the equipment. The whole process realizes the directional and automatic processing of burrs from generation to discharge, effectively maintaining the cleanliness of the working environment.

[0043] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
