Description

Technical Field

[0001] This invention belongs to the field of metal scrap shearing technology, specifically an automatic metal scrap shearing device. Background Technology

[0002] Metal scrap mainly refers to various metals and alloys discarded after use, and is an important recycled raw material for the smelting and production of industrial metals such as steel, copper, lead, aluminum, and zinc. Through recycling and processing, valuable components such as tin, nickel, magnesium, and various precious metals can also be extracted from it. Scrap metal often contains organic impurities, and the metallic impurities contained therein are divided into three categories: beneficial, inert, and harmful. Among them, harmful impurities can be diluted to compliant ranges by adding pure metals, or effectively removed in subsequent refining processes to ensure that the quality of recycled metal meets standards.

[0003] A patent with publication number CN215145110U discloses a metal scrap shearing machine, including a fixed frame on one side of the top of a base plate and a support frame on the side of the top of the base plate away from the fixed frame. The base plate includes a material box at the top of the base plate, a feeding trough on one side inside the material box, a material inlet on the side of the top of the material box near the fixed frame that extends into the feeding trough, movable grooves at both ends on the side of the top of the material box, a pusher plate inside the feeding trough, and movable blocks at both ends of the top of the pusher plate that extend into the movable groove.

[0004] In existing metal scrap shearing equipment, during long-term continuous operation, the cutting blades must constantly come into direct contact and rub against various types of metal scrap with varying hardness and complex shapes. Under the high-frequency shearing impact and continuous friction, the blades are prone to wear and dulling, and can also suffer damage such as curling, chipping, notching, and burrs. Deterioration of the blade condition directly leads to a significant decrease in shearing performance, resulting in uneven cuts and rough surfaces. It can also cause problems such as material clamping, jamming, increased shearing resistance, and incomplete material cutting. This not only reduces scrap processing efficiency and finished product quality but also increases equipment load, exacerbates wear on the hydraulic system and transmission components, increases equipment failure rate, shortens blade life, and raises subsequent maintenance and replacement costs, seriously affecting the stable and continuous operation of the equipment.

[0005] Therefore, the present invention provides an automatic metal scrap shearing device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an automatic metal scrap shearing device, including a machine body, a cutting blade fixedly connected to the top of the machine body, an auxiliary blade arranged below the machine body, the auxiliary blade being parallel to the cutting blade, a rotating plate rotatably connected to one side of the cutting blade, a fixed plate fixedly connected to one end of the rotating plate, and a processing component arranged on one side of the fixed plate. The processing component includes an auxiliary grinding plate slidably connected to one side of the fixed plate, and the auxiliary grinding plate can perform grinding work simultaneously along the auxiliary blade and the cutting blade. A sliding plate is slidably connected to the lower surface of the fixed plate. An auxiliary component is provided on one side of the sliding plate. The auxiliary component includes two storage boxes symmetrically arranged on one side of the sliding plate. A trigger is provided on one side of the sliding plate. The trigger is activated during the sliding of the auxiliary grinding plate to assist the auxiliary grinding plate in grinding. A sealing cover is fixed to one side of the storage box for adding coolant.

[0008] Preferably, the processing component includes a first guide rail formed on the lower surface of a fixed plate, a first guide block slidably connected inside the first guide rail, a sliding plate fixedly connected to one side of the first guide block, a lead screw rotatably connected to one side of the sliding plate, and an auxiliary grinding plate slidably connected to the circumferential surface of the lead screw.

[0009] Preferably, the auxiliary grinding plate has an "L" shaped cross-section, and the auxiliary grinding plate can simultaneously grind the upper surface and the side surface of the auxiliary blade.

[0010] Preferably, the auxiliary component further includes a connecting groove inside the storage box, a connecting spring fixed to the inner wall of the connecting groove, a protrusion fixed to one end of the connecting spring, a connecting hole inside the groove, limit holes on both sides of the protrusion, an opening in the inner wall of the connecting groove, and a spray hole on the surface of the auxiliary grinding plate.

[0011] Preferably, a cleaning assembly is provided on one side of the fixed plate. The cleaning assembly includes a second guide rail opened on one side of the fixed plate, a second guide block slidably connected inside the second guide rail, a telescopic rod fixedly connected to the upper surface of the second guide block, a positioning block fixedly connected to the upper surface of the telescopic rod, and a scraper fixedly connected to one side of the positioning block.

[0012] Preferably, the upper surface of the fixing plate is provided with a positioning hole, and two springs are fixedly connected inside the positioning hole. The top ends of the two springs are fixedly connected with the same insert post, and the lower surface of the positioning block is provided with an insertion hole.

[0013] Preferably, the positioning block and the scraper are both made of frosted material. The positioning block and the scraper can grind and clean the lower surface of the cutter. The upper surface of the positioning block and the scraper are provided with several auxiliary holes.

[0014] Preferably, during the metal scrap shearing process, after the metal scrap is sorted and pushed, it is positioned above the auxiliary blade below the machine body. Then, the hydraulic cylinder at the top of the machine body is activated to drive the cutter downward, thereby shearing the metal scrap. After the shearing is completed, the cutter moves upward, and then the rotating plate is activated. The rotating plate rotates and drives the fixed plate to rotate between the cutter and the auxiliary blade. Then, the first guide rail on the lower surface of the fixed plate is activated. The first guide rail drives the first guide block to move the sliding plate closer to the auxiliary blade until the sliding plate abuts against the auxiliary plate, thereby driving the auxiliary grinding plate on one side of the sliding plate to perform grinding work.

[0015] Preferably, when the auxiliary grinding plate is working, the lead screw on one side of the sliding plate is activated, driving the auxiliary grinding plate to slide along the auxiliary blade for grinding. While the auxiliary grinding plate is sliding, it squeezes the protrusion on one side of the sliding plate. The protrusion is squeezed, which in turn squeezes the connecting spring on one side, causing the protrusion to retract into the connecting groove. After the protrusion retracts into the connecting groove, the limiting holes on both sides of the protrusion align with the openings on the inner wall of the connecting groove. At this time, the pressure pump inside the storage tank injects the coolant stored in the storage tank into the protrusion, and then sprays it out along the connecting hole inside the protrusion. The pressurized coolant is sprayed out from the spray hole on the side of the auxiliary grinding plate during the sliding process of the auxiliary grinding plate, spraying between the auxiliary grinding plate and the auxiliary blade for cooling and lubrication, thus assisting the grinding work of the auxiliary grinding plate.

[0016] Preferably, while the auxiliary grinding plate is performing the grinding work, a positioning block is slidably connected in the second guide rail on one side of the fixed plate. By activating the electric telescopic rod on the upper surface of the second guide block, the telescopic rod pushes the positioning block upward until it abuts against the cutter. The upper surface of the positioning block is inclined to match the cutter. In addition, the positioning block, driven by the second guide block, slides along the lower surface of the cutter with the scraper. During the cleaning of the lower surface of the cutter, the telescopic rod gradually retracts to adapt to the inclined surface of the cutter. When the positioning block moves to one end of the second guide rail, it will squeeze the insertion post, causing the insertion post to retract into the positioning hole. Then, when the insertion post is aligned with the insertion hole on the lower surface of the positioning block and inserted, the pressure sensor built into the insertion hole receives a signal and activates the storage tank on the lower surface of the fixed plate. The storage tank pressurizes the built-in coolant into the positioning block and scraper to cool the positioning block and scraper. At the same time, the coolant will spray out from the openings on the surface of the positioning block and scraper to flush the lower surface of the cutter.

[0017] The beneficial effects of this invention are as follows: 1. The automatic metal scrap shearing equipment of the present invention integrates metal scrap shearing and blade grinding through the cooperation of shearing and auxiliary grinding plate. After shearing, the processing component can be automatically pushed between the cutter and the auxiliary blade. The auxiliary grinding plate is driven by the guide rail to grind the blade edge. There is no need for manual disassembly of the blade or separate maintenance. It can promptly repair problems such as blade dulling, curling, and burrs caused by shearing, effectively ensuring blade sharpness, improving the subsequent shearing quality, reducing problems such as uneven cuts, material jamming, and high shearing resistance. At the same time, it saves the tedious process of manual grinding, shortens equipment downtime maintenance time, reduces blade wear, extends the service life of the cutter, ensures continuous and stable operation of the equipment, and improves the overall processing efficiency.

[0018] 2. The automatic metal scrap shearing device of the present invention uses a lead screw to drive an auxiliary grinding plate to reciprocate and slide for grinding. Simultaneously, the elastic extension and contraction of a protrusion and connecting spring triggers the release of coolant. During grinding, the protrusion is compressed, ensuring precise alignment of the limiting hole and the opening. A pressure pump then delivers coolant, which is sprayed through the internal channel of the protrusion and onto the grinding contact surface via a nozzle. This allows for real-time cooling of the auxiliary grinding plate and blade during grinding, reducing blade annealing and grinding plate wear caused by high frictional temperatures. Simultaneously, it provides lubrication, reducing grinding resistance, improving grinding accuracy and efficiency, and preventing secondary damage to the blade. By achieving simultaneous grinding, cooling, and lubrication, it effectively extends the service life of the cutting blade and grinding components, reduces maintenance frequency, and ensures stable operation of grinding and shearing operations.

[0019] 3. The automatic metal scrap shearing device of this invention uses a second guide rail and an electric telescopic rod to drive a positioning block to fit against the cutter. An inclined adaptive structure fits the cutter's beveled surface, and a scraper slides to clean iron filings, oxide scale, and other impurities from the lower surface of the cutter. The telescopic rod can adaptively adjust its extension to fit the cutter's beveled surface structure, ensuring a good cleaning fit. Alignment of the insertion post and insertion hole triggers a pressure sensor, automatically controlling the coolant output from the storage tank to cool the positioning block and scraper while simultaneously flushing, cooling, and cleaning the cutter surface. This allows for simultaneous blade grinding, impurity cleaning, and cooling / lubrication, effectively preventing blade wear caused by residual iron filings, improving cutter cleanliness and grinding quality, extending cutter lifespan, and ensuring stable and efficient shearing operations.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 7 As shown in the embodiment of the present invention, an automatic metal scrap shearing device has a cutter 11 fixedly connected to the top of the machine body 1, and an auxiliary cutter 12 arranged below the machine body 1. The auxiliary cutter 12 is parallel to the cutter 11. A rotating plate 2 is rotatably connected to one side of the cutter 11, and a fixed plate 21 is fixedly connected to one end of the rotating plate 2. A processing component is arranged on one side of the fixed plate 21. The processing component includes an auxiliary grinding plate 26 slidably connected to one side of the fixed plate 21. The auxiliary grinding plate 26 can perform grinding work simultaneously along the auxiliary cutter 12 and the cutter 11. A sliding plate 24 is slidably connected to the lower surface of the fixed plate 21. An auxiliary component is arranged on one side of the sliding plate 24. The auxiliary component includes two symmetrically arranged on one side of the sliding plate 24. A storage tank 29 has a trigger on one side of a sliding plate 24. The trigger is activated during the sliding of the auxiliary grinding plate 26, which then performs grinding work. A sealing cover 210 is fixed to one side of the storage tank 29 for adding coolant. The processing assembly includes a first guide rail 22 on the lower surface of a fixed plate 21. A first guide block 23 is slidably connected inside the first guide rail 22. A sliding plate 24 is fixed to one side of the first guide block 23. A lead screw 25 is rotatably connected to one side of the sliding plate 24. The auxiliary grinding plate 26 is slidably connected to the circumference of the lead screw 25. The cross-section of the auxiliary grinding plate 26 is "L" shaped, and the auxiliary grinding plate 26 can simultaneously grind the upper surface and the side surface of the auxiliary blade 12.

[0024] Specifically, in the long-term continuous operation of existing metal scrap shearing equipment, the cutting blade 11 needs to continuously come into direct contact and rub against various types of metal scrap with different hardness and complex shapes. Under the high-frequency shearing impact and continuous friction, the blade is prone to wear and dulling, and will also produce damage problems such as curling, chipping, notching, and burrs. After the blade condition deteriorates, it directly leads to a significant decrease in shearing performance, and the scrap is prone to uneven cuts and rough cross-sections during shearing. At the same time, it can also cause problems such as material clamping, jamming, increased shearing resistance, and inability to cut the material. This not only reduces the scrap processing efficiency and the quality of the finished product, but also increases the equipment load, aggravates the wear of the hydraulic system and transmission components, increases the equipment failure rate, shortens the blade life, increases the later maintenance and replacement costs, and seriously affects the stable and continuous operation of the equipment. Therefore, the present invention solves the above problems by setting the above structure. First, during the metal scrap shearing process, the metal scrap is positioned above the auxiliary blade 12 below the machine body 1 after being sorted and pushed. Then, the hydraulic cylinder at the top of the machine body 1 is activated to drive the cutter 11 to move down, thereby shearing the metal scrap. After the shearing is completed, the cutter 11 moves up, and then the rotating plate 2 is activated. The rotating plate 2 rotates and drives the fixed plate 21 to rotate between the cutter 11 and the auxiliary blade 12. Then, the first guide rail 22 on the lower surface of the fixed plate 21 is activated. The first guide rail 22 drives the first guide block 23 to drive the sliding plate 24 to move closer to the auxiliary blade 12 until the sliding plate 24 abuts against the auxiliary plate, thereby driving the auxiliary grinding plate 26 on one side of the sliding plate 24 to perform grinding work. By combining shearing with auxiliary grinding plate 26, the shearing of metal scrap and the grinding of the blade are integrated. After shearing, the processing component can be automatically pushed between the cutter 11 and the auxiliary blade 12. The auxiliary grinding plate 26 is driven by the guide rail to grind the blade edge. There is no need to manually disassemble the blade or stop the machine for separate maintenance. It can promptly repair problems such as blade dulling, curling, and burrs caused by shearing, effectively ensuring the sharpness of the blade, improving the subsequent shearing quality, reducing problems such as uneven cuts, material jamming, and high shearing resistance. At the same time, it saves the tedious process of manual grinding, shortens the equipment downtime for maintenance, reduces blade wear, extends the service life of the cutter 11, ensures continuous and stable operation of the equipment, and improves the overall processing efficiency.

[0025] like Figure 5As shown, the auxiliary components in this embodiment also include a connecting groove 222 inside the storage box 29. A connecting spring 223 is fixedly connected to the inner wall of the connecting groove 222. A protrusion 28 is fixedly connected to one end of the connecting spring 223. A connecting hole 224 is opened inside the spring. Limiting holes 225 are opened on both sides of the protrusion 28. An opening 211 is opened on the inner wall of the connecting groove 222. A spray hole 27 is opened on the surface of the auxiliary grinding plate 26. A cleaning component is provided on one side of the fixed plate 21. The cleaning component includes a second guide rail 219 opened on one side of the fixed plate 21. A second guide block 220 is slidably connected inside the second guide rail 219. A telescopic rod 212 is fixedly connected to the upper surface of the second guide block 220. A positioning block 213 is fixedly connected to the upper surface of the telescopic rod 212. A scraper 214 is fixedly connected to one side of the positioning block 213.

[0026] Specifically, when the auxiliary grinding plate 26 is working, the lead screw 25 on one side of the sliding plate 24 is activated. The lead screw 25 drives the auxiliary grinding plate 26 to slide along the auxiliary blade 12 to perform grinding work. While the auxiliary grinding plate 26 is sliding, it will squeeze the protrusion 28 on one side of the sliding plate 24. The protrusion 28 is squeezed, which in turn squeezes the connecting spring 223 on one side. At the same time, the protrusion 28 retracts into the connecting groove 222. After the protrusion 28 retracts into the connecting groove 222, the limiting holes 225 on both sides of the protrusion 28 are aligned with the openings 211 on the inner wall of the connecting groove 222. At this time, the pressure pump inside the storage tank 29 will inject the coolant stored in the storage tank 29 into the protrusion 28, and then spray it out along the connecting hole 224 inside the protrusion 28. The pressurized coolant will be sprayed out from the spray hole 27 on the side of the auxiliary grinding plate 26 during the sliding process of the auxiliary grinding plate 26, and sprayed between the auxiliary grinding plate 26 and the auxiliary blade 12 to perform cooling and lubrication work, assisting the grinding work of the auxiliary grinding plate 26. The auxiliary grinding plate 26 is driven to reciprocate and slide for grinding by the lead screw 25. At the same time, the elastic extension and contraction of the protrusion 28 and the connecting spring 223 triggers the coolant. During the grinding operation, the protrusion 28 is compressed, so that the limiting hole 225 and the opening 211 are precisely aligned. The pressure pump then delivers coolant, which is sprayed onto the grinding contact surface through the spray hole 27 through the internal channel of the protrusion 28. This can cool the auxiliary grinding plate 26 and the blade in real time during the grinding process, reducing the problems of blade annealing and grinding plate wear caused by friction and high temperature. At the same time, it also plays a lubricating role, reducing grinding resistance, improving grinding accuracy and efficiency, avoiding secondary damage to the blade, and realizing the simultaneous operation of grinding, cooling and lubrication. This effectively extends the service life of the cutter 11 and the grinding components, reduces the frequency of maintenance, and ensures stable operation of grinding and shearing operations.

[0027] Example 2: Figures 1 to 7As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the upper surface of the fixing plate 21 is provided with a positioning hole 216, and two springs 218 are fixedly connected inside the positioning hole 216. The top of the two springs 218 is fixedly connected with the same insert post 217. The lower surface of the positioning block 213 is provided with an insertion hole 215. The positioning block 213 and the scraper 214 are both made of frosted material. The positioning block 213 and the scraper 214 can perform grinding and cleaning work on the lower surface of the cutter 11. The upper surfaces of the positioning block 213 and the scraper 214 are provided with several auxiliary holes 221.

[0028] Specifically, while the auxiliary grinding plate 26 is performing grinding, a positioning block 213 is slidably connected within the second guide rail 219 on one side of the fixed plate 21. By activating the electric telescopic rod 212 on the upper surface of the second guide block 220, the telescopic rod 212 pushes the positioning block 213 upward until it abuts against the cutter 11. The upper surface of the positioning block 213 is inclined to match the cutter 11. Additionally, driven by the second guide block 220, the positioning block 213 carries the scraper 214 along the lower surface of the cutter 11 to clean the lower surface of the cutter 11. During this cleaning process, the telescopic rod 212 gradually retracts to accommodate the movement of the cutting rod. When the positioning block 213 moves to one end of the second guide rail 219, the inclined surface of the cutter 11 will squeeze the insertion post 217, causing the insertion post 217 to first retract into the positioning hole 216. Then, when the insertion post 217 is aligned with and inserted into the insertion hole 215 on the lower surface of the positioning block 213, the pressure sensor built into the insertion hole 215 receives the signal and activates the storage box 29 on the lower surface of the fixing plate 21. The storage box 29 pressurizes the built-in coolant into the positioning block 213 and the scraper 214 to cool down the positioning block 213 and the scraper 214. At the same time, the coolant will spray out from the opening 211 on the surface of the positioning block 213 and the scraper 214 to flush the lower surface of the cutter 11. The second guide rail 219 and the electric telescopic rod 212 drive the positioning block 213 to fit against the cutter 11. The inclined fitting structure conforms to the beveled surface of the cutter 11, and the scraper 214 slides to clean iron filings, oxide scale, and other impurities from the lower surface of the cutter 11. The telescopic rod 212 can adaptively adjust its extension to fit the beveled structure of the cutter 11, ensuring a good cleaning fit. The alignment of the insertion post 217 and the insertion hole 215 triggers a pressure sensor, automatically controlling the storage tank 29 to output coolant. This cools the positioning block 213 and the scraper 214 while simultaneously rinsing, cooling, and cleaning the surface of the cutter 11. This allows for simultaneous blade grinding, impurity cleaning, and cooling / lubrication, effectively preventing blade wear caused by residual iron filings, improving the cleanliness and grinding quality of the cutter 11, extending its service life, and ensuring stable and efficient shearing operations.

[0029] Working principle: First, during the metal scrap shearing process, the metal scrap is positioned above the auxiliary blade 12 below the machine body 1 after being sorted and pushed. Then, the hydraulic cylinder at the top of the machine body 1 is activated to drive the cutter 11 to move down, thereby shearing the metal scrap. After the shearing is completed, the cutter 11 moves up, and then the rotating plate 2 is activated. The rotating plate 2 rotates and drives the fixed plate 21 to rotate between the cutter 11 and the auxiliary blade 12. Then, the first guide rail 22 on the lower surface of the fixed plate 21 is activated. The first guide rail 22 drives the first guide block 23 to move the sliding plate 24 closer to the auxiliary blade 12 until the sliding plate 24 abuts against the auxiliary plate, thereby driving the auxiliary grinding plate 26 on one side of the sliding plate 24 to perform grinding work. By combining shearing with auxiliary grinding plate 26, the integration of metal scrap shearing and blade grinding is achieved. After shearing, the processing component can be automatically pushed between the cutter 11 and the auxiliary blade 12. The auxiliary grinding plate 26 is driven by the guide rail to grind the blade edge. There is no need to manually disassemble the blade or stop the machine for separate maintenance. It can promptly repair problems such as blade dulling, curling, and burrs caused by shearing, effectively ensuring blade sharpness, improving the subsequent shearing quality, reducing problems such as uneven cuts, material jamming, and high shearing resistance. At the same time, it saves the tedious process of manual grinding, shortens equipment downtime maintenance time, reduces blade wear, extends the service life of the cutter 11, ensures continuous and stable operation of the equipment, and improves overall processing efficiency. When the auxiliary grinding plate 26 is working, the lead screw 25 on one side of the sliding plate 24 is activated. The lead screw 25 drives the auxiliary grinding plate 26 to slide along the auxiliary blade 12 to perform grinding work. While the auxiliary grinding plate 26 is sliding, it will squeeze the protrusion 28 on one side of the sliding plate 24. The protrusion 28 is squeezed, which in turn squeezes the connecting spring 223 on one side. At the same time, the protrusion 28 retracts into the connecting groove 222. After the protrusion 28 retracts into the connecting groove 222, the limiting holes 225 on both sides of the protrusion 28 are aligned with the openings 211 on the inner wall of the connecting groove 222. At this time, the pressure pump inside the storage tank 29 will inject the coolant stored in the storage tank 29 into the protrusion 28, and then spray it out along the connecting hole 224 inside the protrusion 28. The pressurized coolant will be sprayed out from the spray hole 27 on the side of the auxiliary grinding plate 26 during the sliding process of the auxiliary grinding plate 26, and sprayed between the auxiliary grinding plate 26 and the auxiliary blade 12 to perform cooling and lubrication work, assisting the grinding work of the auxiliary grinding plate 26. The auxiliary grinding plate 26 is driven to reciprocate and slide for grinding by the lead screw 25. At the same time, the elastic extension and contraction of the protrusion 28 and the connecting spring 223 triggers the coolant. During the grinding operation, the protrusion 28 is compressed, so that the limiting hole 225 and the opening 211 are precisely aligned. The pressure pump then delivers coolant, which is sprayed onto the grinding contact surface through the spray hole 27 through the internal channel of the protrusion 28. This can cool the auxiliary grinding plate 26 and the blade in real time during the grinding process, reducing the problems of blade annealing and grinding plate wear caused by friction and high temperature. At the same time, it also plays a lubricating role, reducing grinding resistance, improving grinding accuracy and efficiency, avoiding secondary damage to the blade, and realizing the simultaneous operation of grinding, cooling and lubrication. This effectively extends the service life of the cutter 11 and the grinding components, reduces the frequency of maintenance, and ensures stable operation of grinding and shearing operations. In addition, while the auxiliary grinding plate 26 is performing grinding work, a positioning block 213 is slidably connected in the second guide rail 219 on one side of the fixed plate 21. By activating the electric telescopic rod 212 on the upper surface of the second guide block 220, the telescopic rod 212 pushes the positioning block 213 upward until it abuts against the cutter 11. The upper surface of the positioning block 213 is inclined to match the cutter 11. Furthermore, under the drive of the second guide block 220, the positioning block 213 carries the scraper 214 to slide along the lower surface of the cutter 11. During the cleaning process of the lower surface of the cutter 11, the telescopic rod 212 gradually retracts to adapt to the movement of the cutting rod. When the positioning block 213 moves to one end of the second guide rail 219, the inclined surface of the cutter 11 will squeeze the insertion post 217, causing the insertion post 217 to first retract into the positioning hole 216. Then, when the insertion post 217 is aligned with and inserted into the insertion hole 215 on the lower surface of the positioning block 213, the pressure sensor built into the insertion hole 215 receives the signal and activates the storage box 29 on the lower surface of the fixing plate 21. The storage box 29 pressurizes the built-in coolant into the positioning block 213 and the scraper 214 to cool down the positioning block 213 and the scraper 214. At the same time, the coolant will spray out from the opening 211 on the surface of the positioning block 213 and the scraper 214 to flush the lower surface of the cutter 11. The second guide rail 219 and the electric telescopic rod 212 drive the positioning block 213 to fit against the cutter 11. The inclined fitting structure conforms to the beveled surface of the cutter 11, and the scraper 214 slides to clean iron filings, oxide scale, and other impurities from the lower surface of the cutter 11. The telescopic rod 212 can adaptively adjust its extension to fit the beveled structure of the cutter 11, ensuring a good cleaning fit. The alignment of the insertion post 217 and the insertion hole 215 triggers a pressure sensor, automatically controlling the storage tank 29 to output coolant. This cools the positioning block 213 and the scraper 214 while simultaneously rinsing, cooling, and cleaning the surface of the cutter 11. This allows for simultaneous blade grinding, impurity cleaning, and cooling / lubrication, effectively preventing blade wear caused by residual iron filings, improving the cleanliness and grinding quality of the cutter 11, extending its service life, and ensuring stable and efficient shearing operations.

5. The automatic metal scrap shearing device according to claim 4, characterized in that: The positioning block (213) and the scraper (214) are both made of frosted material. The positioning block (213) and the scraper (214) can grind and clean the lower surface of the cutter (11). The upper surface of the positioning block (213) and the scraper (214) are provided with several auxiliary holes (221).

6. The automatic metal scrap shearing device according to claim 2, characterized in that: When the auxiliary grinding plate (26) is working, the lead screw (25) on one side of the sliding plate (24) is activated. The lead screw (25) drives the auxiliary grinding plate (26) to slide along the auxiliary cutter (12) to perform grinding work. While the auxiliary grinding plate (26) is sliding, it will squeeze the protrusion (28) on one side of the sliding plate (24). The protrusion (28) is squeezed, which in turn squeezes the connecting spring (223) on one side. At the same time, the protrusion (28) retracts into the connecting groove (222). After the protrusion (28) retracts into the connecting groove (222), the limiting springs on both sides of the protrusion (28) are closed. The positioning hole (225) is aligned with the opening (211) on the inner wall of the connecting groove (222). At this time, the pressure pump inside the storage tank (29) will inject the coolant stored in the storage tank (29) into the protrusion (28), and then spray it out along the connecting hole (224) inside the protrusion (28). The pressurized coolant will be sprayed out from the spray hole (27) on the side of the auxiliary grinding plate (26) during the sliding process of the auxiliary grinding plate (26), and sprayed between the auxiliary grinding plate (26) and the auxiliary blade (12) to perform cooling and lubrication work, and assist the grinding work of the auxiliary grinding plate (26).

7. The automatic metal scrap shearing device according to claim 5, characterized in that: While the auxiliary grinding plate (26) is grinding, a positioning block (213) is slidably connected in the second guide rail (219) on one side of the fixed plate (21). By activating the telescopic rod (212) on the upper surface of the second guide block (220), the telescopic rod (212) pushes the positioning block (213) upward. The positioning block (213) moves upward until it abuts against the cutter (11). The upper surface of the positioning block (213) is inclined to match the cutter (11). In addition, under the drive of the second guide block (220), the positioning block (213) carries the scraper (214) to slide along the lower surface of the cutter (11). During the cleaning of the lower surface of the cutter (11), the telescopic rod (212) gradually retracts to adapt to the cutter (11). When the positioning block (213) moves to one end of the second guide rail (219), it will squeeze the insertion post (217), causing the insertion post (217) to first retract into the positioning hole (216). Then, when the insertion post (217) is aligned with the insertion hole (215) on the lower surface of the positioning block (213) and inserted, the pressure sensor built into the insertion hole (215) receives the signal and starts the storage box (29) on the lower surface of the fixing plate (21). The storage box (29) pressurizes the built-in coolant into the positioning block (213) and scraper (214) to cool down the positioning block (213) and scraper (214). At the same time, the coolant will spray out from the opening (211) on the surface of the positioning block (213) and scraper (214) to flush the lower surface of the cutter (11).
