Description

Technical Field

[0001] The present invention relates to the technical field of plate punching equipment, and particularly to a plate punching device for manufacturing mechanical parts. Background Art

[0002] Mechanical parts refer to the components used in mechanical equipment to achieve specific functions. They are diverse in types and complex in design, and need to meet requirements such as strength, precision, wear resistance, etc., such as gears, crankshafts, flanges, etc. The plates commonly used in the manufacturing of mechanical parts are divided into metal plates and non-metal plates. When processing plates, a punching device is usually required to punch holes in the plates, and it needs to be applicable to various types of plates.

[0003] Among them, when drilling metal plates with a radial drill press, multiple holes often need to be processed at one time. There are usually burrs around the processed holes. However, the radial drill press is usually manually controlled for the drilling position. After drilling is completed, the tool needs to be replaced to remove the burrs. However, due to manual control, it may be difficult for the tool to align with the center of the hole, affecting the removal of the burrs. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a plate punching device for manufacturing mechanical parts, including a base, a vise fixedly connected to the top of the base, and a support column fixedly connected to the top of the base;

[0005] A drilling mechanism, a support assembly is fixedly installed at the top of the drilling mechanism, and a driving assembly is installed at the top of the drilling mechanism for drilling the plate;

[0006] A deburring mechanism, which is installed at the top of the drilling mechanism for removing burrs around the holes of the plate; and

[0007] A cleaning mechanism, which is located inside the deburring mechanism for cleaning the debris generated during drilling;

[0008] A sliding frame is slidably connected to the outer wall of the support column, a sliding table is slidably connected to the side wall of the sliding frame, a fixed cylinder is rotatably connected to the bottom of the sliding table, and three tapered blocks are arranged at the bottom of the fixed cylinder;

[0009] Among them, the plate to be processed is placed on the vise and fixed by the vise, then the plate is drilled by the drilling mechanism, and then the burrs around the plate are removed by the deburring mechanism, so that drilling and deburring of the hole edge are carried out simultaneously, reducing the operation steps and improving the processing efficiency. Finally, the debris during drilling is cleaned by the cleaning mechanism to prevent the deburring mechanism from surrounding the edge of the hole and affecting the discharge of the debris.

[0010] Preferably, the drilling mechanism includes:

[0011] The supporting component is fixedly arranged on the top of the base and is used for fixing the plate to be processed;

[0012] The driving component is slidably arranged at the side wall of the sliding frame and is used for drilling holes in the plate;

[0013] Among them, the operator places the plate to be processed on the top of the supporting component, fixes the plate with a vise, and then makes the driving component approach the plate to drill holes in the fixed plate.

[0014] Preferably, the removing mechanism includes:

[0015] The telescopic component is fixedly arranged at the bottom of the fixed cylinder through a fixing piece and is used for vertical sliding;

[0016] The fixing piece includes three arc-shaped connecting blocks fixedly connected to the bottom of the fixed cylinder, and arc-shaped telescopic sleeves are slidably connected to the inner walls of the three arc-shaped connecting blocks;

[0017] The extrusion component is fixedly arranged at the bottom of the fixed cylinder through a connecting piece and is used for extruding the telescopic component;

[0018] The connecting piece includes three inclined panels fixedly connected to the bottom of the fixed cylinder, and spring plates are slidably connected to the inner walls of the three arc-shaped connecting blocks;

[0019] Among them, during the process of the driving component approaching the plate, the telescopic component approaches the plate, makes the telescopic component contact with the plate, and is extruded, so that the telescopic component retracts and contacts with the extrusion component, and the scraper in the telescopic component extends out to remove burrs. During the process of drilling holes in the plate, it fits the edge of the hole to remove the burrs at the edge of the hole, effectively preventing it from being difficult to align with the center of the hole when replacing the tool to remove burrs after drilling is completed, and realizing the synchronous completion of drilling and deburring.

[0020] Preferably, the cleaning mechanism includes:

[0021] The air jetting component is slidably arranged on the inner wall of the fixed cylinder through a sliding piece and is used for jetting gas to remove debris;

[0022] The sliding piece includes a spring ring slidably connected to the inner wall of the fixed cylinder, and a connecting rod is fixedly connected to the bottom of the spring ring;

[0023] The blocking component is fixedly arranged on the top of the spring ring through a support piece and is used for blocking gas;

[0024] The connecting piece includes three push rods fixedly connected to the top of the spring ring, and three connecting plates are fixedly connected to the bottom of the spring ring;

[0025] Among them, by squeezing the gas in the fixed cylinder through the jet component, the gas will be blocked by the blocking component, causing the gas pressure to rise, and finally spraying out towards the drilling position, accelerating the discharge speed of the debris. By enabling the air flow to synchronously cover the chip discharge path when the driving component rotates, the chips can be washed away, reducing the residue in the hole, and effectively preventing the telescopic component from blocking the chip discharge path around the driving component and affecting the discharge of the debris.

[0026] Preferably, the support component includes a first motor fixedly connected to the top of the support column. A threaded rod is rotatably connected to the inner wall of the support column. The bottom output end of the first motor is fixedly connected to the top of the threaded rod. The outer wall of the threaded rod is threadedly connected to the inner wall of the sliding frame.

[0027] Among them, the operator places the plate to be processed on the vise, fixes the plate through the vise, and then starts the first motor to rotate, driving the threaded rod to rotate, causing the sliding frame to descend and approach the plate.

[0028] Preferably, the driving component includes a second motor fixedly connected to the top of the sliding table. A rotating rod is rotatably connected to the inner wall of the sliding table.

[0029] The bottom output end of the second motor is fixedly connected to the top of the rotating rod. A drill bit is fixedly connected to the bottom of the rotating rod.

[0030] Among them, by starting the second motor to rotate the drill bit, when the sliding frame descends, it will drive the sliding table to descend, bringing the drill bit closer to the plate to drill the plate.

[0031] Preferably, the telescopic component includes a tapered scraper slidably connected to the inner wall of the tapered block. The side walls of the three tapered blocks are slidably connected to the side walls of the three arc-shaped telescopic sleeves. The inner wall of the fixed cylinder is fixedly connected to the outer wall of the rotating rod.

[0032] Among them, when the rotating rod rotates, it will cause the fixed cylinder to rotate and the tapered block to rotate. At the same time, as the sliding table continues to descend, it will cause the fixed cylinder to descend, making the tapered block descend and contact the plate, causing the tapered block to be squeezed and move upward, making the arc-shaped telescopic sleeve retract and rise. The movement path of the tapered block is controlled by the arc-shaped telescopic sleeve to make it move up and down.

[0033] Preferably, the extrusion component includes three spring rods arranged on the outer wall of the drill bit. The outer walls of the three spring rods are slidably connected to the inner walls of the three tapered blocks.

[0034] The bottoms of the three spring rods are fixedly connected to the tops of the three tapered scrapers. Spring return rods are slidably connected to the inner walls of the three spring rods.

[0035] Among them, when the conical block rises, it drives the spring rod and the spring return rod to move until the spring return rod contacts the inclined surface of the inclined panel. Then the inclined panel will squeeze the spring return rod to move towards the arc-shaped telescopic sleeve. As the spring rod continues to rise, the spring return rod will contact the bottom of the arc-shaped telescopic sleeve. When the spring rod continues to rise, the spring return rod will push the arc-shaped telescopic sleeve to rise, causing the arc-shaped telescopic sleeve to squeeze the spring plate, enabling the spring plate to accumulate elastic force for recovery. Since the elastic force of the spring plate is greater than that of the spring rod, the spring rod will be pressed down, causing the conical scraper to descend, so that the conical scraper squeezes the edge of the hole. At the same time, when the fixed cylinder rotates, it will cause the arc-shaped connecting block, the arc-shaped telescopic sleeve and the conical block to rotate, thereby making the conical scraper rotate to cut the edge of the hole and scrape off the burrs on the edge of the hole. By synchronously rotating the drill bit and the conical scraper, during the process of machining the hole in the plate, it fits the edge of the hole and removes the burrs on the edge of the hole, effectively preventing the difficulty of aligning the center of the hole when replacing the tool to remove the burrs after drilling is completed, and achieving the synchronous completion of drilling and deburring.

[0036] Preferably, the air jet assembly includes a concave-convex ring fixedly connected to the bottom of the sliding table, and a plurality of air inlet holes are provided in the inner wall of the fixed cylinder;

[0037] Three air jet pipes are fixedly connected to the inner wall of the fixed cylinder, and the inner walls of the spring rings are all slidably connected to the outer walls of the three spring rings;

[0038] Among them, when the fixed cylinder rotates, it will cause the connecting rod to rotate on the top of the concave-convex ring. When the connecting rod moves from the concave position of the concave-convex ring to the convex position, the connecting rod will be squeezed and move upward, causing the spring ring to rise and accumulate elastic force for recovery. When the spring ring moves past the air inlet hole, it will squeeze the gas in the fixed cylinder. At this time, the squeezed gas will be blocked by the spring air blocking plate, so the gas pressure will increase.

[0039] Preferably, the blocking assembly includes a spring air blocking plate slidably connected to the inner wall of the air jet pipe, and a rocker is rotatably connected to the inner walls of the three arc-shaped connecting blocks;

[0040] Among them, until the spring ring drives the push rod to contact the spring air-blocking plate, the spring air-blocking plate is pushed to move, canceling the block of the gas, allowing high-pressure gas to enter the spray pipe. Since the drill bit and the spray pipe rotate synchronously, the spray pipe and the drill bit are relatively stationary, and the spray pipe faces the chip discharge groove of the drill bit. Therefore, the high-pressure gas will spray out towards the chip discharge groove of the drill bit, discharging the chips. When the fixed cylinder continues to rotate, the connecting rod will contact the concave position of the concave-convex ring again, and the resilience of the spring ring will be released, causing it to return to its original position. External gas will enter the fixed cylinder through the air inlet hole to complete the gas replenishment until the connecting rod is pressed and rises again. This process repeats continuously, continuously spraying gas on the drill bit. By allowing the air flow to cover the chip discharge path synchronously when the drill bit rotates, it can wash away the chips, reduce the residue in the hole, effectively prevent the tapered block from fitting around the drill bit and blocking the chip discharge path, and affect the discharge of chips.

[0041] The present invention has the following beneficial effects:

[0042] (1) When the present invention is in use, after the user fixes the plate, through the support component and the drive component, the drill bit rotates to drill the plate until the spring return rod is pressed to contact the bottom of the arc-shaped telescopic sleeve, such as Figure 6 : the state of G in the figure, allowing the tapered scraper to squeeze the edge of the hole and scrape off the burrs on the edge of the hole. By rotating the drill bit and the tapered scraper synchronously and fitting the edge of the hole, the burrs on the edge of the hole can be removed, effectively preventing the difficulty of aligning the center of the hole when replacing the tool to remove burrs after drilling is completed, and realizing the synchronous completion of drilling and deburring.

[0043] (2) During the process of the tapered scraper scraping off the burrs in the present invention, as the spring rod continues to move, the spring return rod will separate from the inclined surface of the inclined panel, causing the spring return rod to separate from the arc-shaped telescopic sleeve. At this time, the thrust on the spring rod disappears, and the squeezing force of the tapered scraper on the plate disappears. At this time, during the feeding process of the drill bit, the tapered scraper will not cut the edge of the hole. During the feeding process of the drill bit, the tapered block will continue to rise, allowing the drill bit to process holes of different depths, effectively preventing over-cutting when the drill bit processes a deeper hole and the tapered scraper continuously cuts the edge of the hole.

[0044] (3) When the fixed cylinder rotates in the present invention, it will cause the connecting rod to rotate on the top of the concave-convex ring, causing the connecting rod to be squeezed, raising the spring ring, squeezing the gas in the fixed cylinder. At this time, the squeezed gas will be blocked by the spring air-blocking plate, so the gas pressure will increase until the push rod pushes the spring air-blocking plate to move, allowing high-pressure gas to enter the spray pipe. The high-pressure gas will spray out towards the chip discharge groove of the drill bit, discharging the chips. By allowing the air flow to cover the chip discharge path synchronously when the drill bit rotates, it can wash away the chips, reduce the residue in the hole, effectively prevent the tapered block from fitting around the drill bit and blocking the chip discharge path, and affect the discharge of chips.

[0045] (4) When the spring ring rises in the present invention, it will drive the connecting plate to rise, making the connecting plate contact the rocker, pushing the rocker to rotate, causing the rocker to push the spring plate to descend, squeezing the arc-shaped telescopic sleeve, enabling the spring plate to accumulate resilience. Among them, when the spring reset rod contacts the arc-shaped telescopic sleeve, as the spring plate descends, the spring rod will receive a greater thrust, enabling the conical scraper to exert a greater extrusion force on the plate to scrape off stubborn burrs, effectively preventing the situation where the material of some plates is too hard and the extrusion force of the conical scraper on the plate is insufficient, which may make it difficult to fully remove the burrs.

[0063] Among them, by placing the plate to be processed on the vise 112, fixing it with the vise 112, then drilling the plate through the drilling mechanism 1, and then removing the burrs around the plate through the removing mechanism 2, the drilling and deburring of the hole edge are carried out simultaneously, reducing the operation steps and improving the processing efficiency. Finally, the debris during drilling is cleaned by the cleaning mechanism 3 to prevent the removing mechanism 2 from surrounding the edge of the hole and affecting the discharge of the debris.

[0070] The fixing piece includes three arc-shaped connecting blocks 212 fixedly connected to the bottom of the fixed cylinder 211, and arc-shaped telescopic sleeves 213 are slidably connected to the inner walls of the three arc-shaped connecting blocks 212;

By making the drive component 12 drive the air flow to synchronously cover the chip discharge path during rotation, the chips can be washed away, reducing the residue in the hole, and effectively preventing the telescopic component 21 from blocking the chip discharge path around the drive component 12 and affecting the discharge of the debris.

[0080] Embodiment 2, please refer to Figures 1 - 8 , the present invention is a plate drilling device for manufacturing mechanical parts. On the basis of Example 1, the support component 11 includes a motor 115 fixedly connected to the top of the support column 113. A threaded rod 116 is rotatably connected to the inner wall of the support column 113. The bottom output end of the motor 115 is fixedly connected to the top of the threaded rod 116, and the outer wall of the threaded rod 116 is threadedly connected to the inner wall of the sliding frame 114;

[0081] Among them, the operator places the plate to be processed on the vise 112, fixes the plate through the vise 112, and then starts the motor 115 to rotate, driving the threaded rod 116 to rotate, so that the sliding frame 114 descends close to the plate.

[0082] The drive component 12 includes a motor 122 fixedly connected to the top of the sliding table 121. A rotating rod 123 is rotatably connected to the inner wall of the sliding table 121;

[0083] The bottom output end of the motor 122 is fixedly connected to the top of the rotating rod 123, and a drill bit 124 is fixedly connected to the bottom of the rotating rod 123;

[0084] Among them, by starting the motor 122 to rotate the drill bit 124, when the sliding frame 114 descends, it will drive the sliding table 121 to descend, bringing the drill bit 124 close to the plate to drill the plate.

[0085] The telescopic assembly 21 includes a conical scraper 215 slidably connected to the inner wall of the conical block 214. The side walls of the three conical blocks 214 are slidably connected to the side walls of the three arc-shaped telescopic sleeves 213. The inner wall of the fixed cylinder 211 is fixedly connected to the outer wall of the rotating rod 123.

[0086] Among them, when the rotating rod 123 rotates, it will cause the fixed cylinder 211 to rotate and the conical block 214 to rotate. At the same time, as the sliding table 121 continues to descend, it will cause the fixed cylinder 211 to descend, so that the conical block 214 descends to contact the plate, causing the conical block 214 to move upward under extrusion, making the arc-shaped telescopic sleeve 213 retract and rise. The movement path of the conical block 214 is controlled by the arc-shaped telescopic sleeve 213, causing it to move up and down.

[0087] The extrusion assembly 22 includes three spring rods 221 arranged on the outer wall of the drill bit 124. The outer walls of the three spring rods 221 are slidably connected to the inner walls of the three conical blocks 214.

[0088] The bottoms of the three spring rods 221 are fixedly connected to the tops of the three conical scrapers 215. Spring return rods 223 are slidably connected to the inner walls of the three spring rods 221.

[0089] Among them, when the conical block 214 rises, it drives the spring rod 221 and the spring return rod 223 to move until the spring return rod 223 contacts the inclined surface of the inclined panel 222. The inclined panel 222 will then squeeze the spring return rod 223 to move towards the arc-shaped telescopic sleeve 213. As the spring rod 221 continues to rise, the spring return rod 223 will contact the bottom of the arc-shaped telescopic sleeve 213, as shown in the state of G in Figure 6. When the spring rod 221 continues to rise, the spring return rod 223 will push the arc-shaped telescopic sleeve 213 to rise, causing the arc-shaped telescopic sleeve 213 to squeeze the spring plate 224, allowing the spring plate 224 to accumulate elastic force. Since the elastic force of the spring plate 224 is greater than the elastic force of the spring rod 221, the spring rod 221 will be pressed down, causing the conical scraper 215 to descend, making the conical scraper 215 squeeze the edge of the hole. At the same time, when the fixed cylinder 211 rotates, it will cause the arc-shaped connecting block 212, the arc-shaped telescopic sleeve 213, and the conical block 214 to rotate, so that the conical scraper 215 rotates, cutting the edge of the hole and scraping off the burrs on the edge of the hole. By the synchronous rotation of the drill bit 124 and the conical scraper 215, during the process of machining the hole in the plate, it fits the edge of the hole and removes the burrs on the edge of the hole, effectively preventing the difficulty of aligning the center of the hole when replacing the tool to remove the burrs after drilling is completed, and achieving the synchronous completion of drilling and deburring.

[0090] The air jet assembly 31 includes a concave-convex ring 313 fixedly connected to the bottom of the sliding table 121. A number of air inlet holes 314 are provided in the inner wall of the fixed cylinder 211.

[0091] Three air injection pipes 315 are fixedly connected to the inner wall of the fixed cylinder 211, and the inner walls of the spring rings 311 are all slidably connected to the outer walls of the three spring rings 311;

[0092] Among them, when the fixed cylinder 211 rotates, the connecting rod 312 will rotate on the top of the concave-convex ring 313. When the connecting rod 312 moves from the concave position of the concave-convex ring 313 to the convex position, the connecting rod 312 will be squeezed upward, causing the spring ring 311 to rise and accumulate resilience. When the spring ring 311 moves past the air inlet hole 314, it will squeeze the gas in the fixed cylinder 211. At this time, the squeezed gas will be blocked by the spring air blocking plate 321, so the gas pressure will increase.

[0093] The blocking assembly 32 includes a spring air blocking plate 321 slidably connected to the inner wall of the air injection pipe 315, and a rocker 324 is rotatably connected to the inner wall of each of the three arc-shaped connecting blocks 212;

[0094] Among them, until the spring ring 311 drives the push rod 322 to contact the spring air blocking plate 321, pushing the spring air blocking plate 321 to move and canceling the block of the gas, allowing the high-pressure gas to enter the air injection pipe 315. Since the drill bit 124 rotates synchronously with the air injection pipe 315, the air injection pipe 315 and the drill bit 124 are relatively stationary, and the air injection pipe 315 faces the chip discharge groove of the drill bit 124. Therefore, the high-pressure gas will spray out towards the chip discharge groove of the drill bit 124 to discharge the chips. When the fixed cylinder 211 continues to rotate, the connecting rod 312 will contact the concave position of the concave-convex ring 313 again, and the resilience of the spring ring 311 will be released, causing it to return to its original position. The outside air will enter the fixed cylinder 211 through the air inlet hole 314 to complete the gas replenishment until the connecting rod 312 is pressed upward again. This process repeats continuously, spraying gas at the drill bit 124. By allowing the airflow to cover the chip discharge path synchronously when the drill bit 124 rotates, it is possible to wash away the chips, reduce the residue in the hole, and effectively prevent the tapered block 214 from fitting around the drill bit 124 and blocking the chip discharge path, which affects the discharge of chips.

[0095] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0096] A specific application of this embodiment is as follows: When the present invention is in use, the user places the plate to be processed on the top of the vise 112, fixes the plate through the vise 112, rotates the threaded rod 116 by starting the first motor 115, makes the sliding frame 114 descend, and the sliding table 121 descend. Then, starts the second motor 122 to rotate the rotating rod 123, makes the fixed cylinder 211 and the drill bit 124 rotate. The descent of the sliding table 121 will make the drill bit 124 descend to contact the plate for drilling the plate. As the sliding table 121 continues to descend, the conical block 214 contacts the plate, causing the conical block 214 to be extruded and move upward, making the arc-shaped telescopic sleeve 213 retract, driving the spring rod 221 and the spring return rod 223 to move until the spring return rod 223 contacts the inclined surface of the inclined panel 222. The inclined panel 222 will then extrude the spring return rod 223 to move towards the arc-shaped telescopic sleeve 213. As the spring rod 221 continues to rise, the spring return rod 223 will contact the bottom of the arc-shaped telescopic sleeve 213, in the state of G in Figure 6. When the spring rod 221 continues to rise, the spring return rod 223 will push the arc-shaped telescopic sleeve 213 to rise, making the arc-shaped telescopic sleeve 213 extrude the spring plate 224, causing the spring plate 224 to accumulate resilience. Since the resilience of the spring plate 224 is greater than the resilience of the spring rod 221, the spring rod 221 will be compressed and descend, making the conical scraper 215 descend, causing the conical scraper 215 to extrude the edge of the hole. At the same time, when the fixed cylinder 211 rotates, it will make the arc-shaped connecting block 212, the arc-shaped telescopic sleeve 213 and the conical block 214 rotate, so that the conical scraper 215 rotates to cut the edge of the hole and scrape off the burrs on the edge of the hole. By the synchronous rotation of the drill bit 124 and the conical scraper 215, during the process of processing the hole in the plate, it fits the edge of the hole and removes the burrs on the edge of the hole, effectively preventing the difficulty in aligning the center of the hole when replacing the tool to remove the burrs after drilling is completed, and achieving the synchronous completion of drilling and deburring;

[0097] Secondly, during the process of the conical scraper 215 scraping off the burrs, the drill bit 124 will continue to feed, making the spring rod 221 continue to rise. As the spring rod 221 continues to move, the spring return rod 223 will separate from the inclined surface of the inclined panel 222, and the resilience of the spring return rod 223 will be released, making the spring return rod 223 return to its position and separate from the arc-shaped telescopic sleeve 213. At this time, the thrust on the spring rod 221 disappears, and the resilience of the spring rod 221 will be released, making the spring rod 221 drive the conical scraper 215 to return to its position, and the extrusion force of the conical scraper 215 on the plate will disappear. At this time, during the feeding process of the drill bit 124, the conical scraper 215 will not cut the edge of the hole. During the feeding process of the drill bit 124, it will make the conical block 214 continue to rise, enabling the drill bit 124 to process holes with different depths, effectively preventing the conical scraper 215 from continuously cutting the edge of the hole when the hole processed by the drill bit 124 is relatively deep, resulting in over-cutting;

[0098] Secondly, when the fixed cylinder 211 rotates, the connecting rod 312 will rotate on the top of the concave-convex ring 313. When the connecting rod 312 moves from the concave position of the concave-convex ring 313 to the convex position, the connecting rod 312 will be squeezed and move upward, causing the spring ring 311 to rise and accumulate resilience. When the spring ring 311 moves past the air inlet hole 314, it will squeeze the gas inside the fixed cylinder 211. At this time, the squeezed gas will be blocked by the spring air-blocking plate 321, so the gas pressure will increase until the spring ring 311 drives the push rod 322 to contact the spring air-blocking plate 321 and push the spring air-blocking plate 321 to move, canceling the block of the gas and allowing the high-pressure gas to enter the spray pipe 315. Since the drill bit 124 rotates synchronously with the spray pipe 315, the spray pipe 315 and the drill bit 124 are relatively stationary, and the spray pipe 315 faces the chip discharge groove of the drill bit 124. Therefore, the high-pressure gas will spray out against the chip discharge groove of the drill bit 124 to discharge the chips. When the fixed cylinder 211 continues to rotate, the connecting rod 312 will contact the concave position of the concave-convex ring 313 again, and the resilience of the spring ring 311 will be released, causing it to return to its original position. The external gas will enter the fixed cylinder 211 through the air inlet hole 314 to complete the gas replenishment until the connecting rod 312 is pressed and rises again. This process repeats continuously, spraying gas on the drill bit 124. By allowing the air flow to cover the chip discharge path synchronously when the drill bit 124 rotates, it is possible to wash away the chips, reduce the residue in the hole, and effectively prevent the conical block 214 from fitting around the drill bit 124 and blocking the chip discharge path, which affects the discharge of chips.

[0099] Secondly, when the spring ring 311 rises, it will drive the connecting plate 323 to rise, causing the connecting plate 323 to contact the rocker 324 and push the rocker 324 to rotate. The side of the rocker 324 in contact with the connecting plate 323 will rise, and the other side will fall. The falling side will push the spring plate 224 to descend, squeezing the arc-shaped telescopic sleeve 213, causing the spring plate 224 to accumulate resilience. Among them, when the spring return rod 223 contacts the arc-shaped telescopic sleeve 213, when the spring plate 224 descends, the spring rod 221 will be subjected to a greater thrust, causing the conical scraper 215 to exert a greater extrusion force on the plate to scrape off stubborn burrs, effectively preventing the conical scraper 215 from having insufficient extrusion force on the plate due to some plate materials being too hard, which may make it difficult to fully remove the burrs.
