Description

Technical Field

[0001] This invention relates to the field of shearing equipment technology, specifically a shearing equipment for internal combustion engine production and processing. Background Technology

[0002] During the production and processing of internal combustion engines, metal sheets need to be sheared. During shearing operations, iron filings, oxide scale, oil stains and other contaminants will inevitably adhere to the surface of the cutting blade. If these contaminants are not cleaned in time, they will increase blade wear, reduce shearing accuracy, and affect the forming quality of the sheet cut. Therefore, shearing equipment usually needs to be equipped with a blade cleaning device.

[0003] Existing cleaning devices cannot adjust their cleaning performance in real time when faced with debris or impurities of varying degrees, resulting in poor cleaning results. Summary of the Invention

[0004] The purpose of this invention is to provide a shearing device for internal combustion engine production and processing, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shearing device for internal combustion engine production and processing, comprising a fluid supply system, a shearing table, a cutting unit, and a lubrication and cleaning unit; the cutting unit includes a drive unit and a cutting blade, the drive unit is mounted on the shearing table, and the output end of the drive unit is connected to the cutting blade; the lubrication and cleaning unit includes a slide rail, a moving mechanism, and a lubricator / cleaner, the slide rail is mounted on the shearing table, and the moving mechanism is mounted on the slide rail; the lubrication / cleaner includes a lubrication table and a scraper, the lubrication table is slidably mounted on the slide rail, the lubrication table is connected to the output end of the moving mechanism, a detection element is provided on the lubrication table corresponding to the position of the scraper / cleaner, a communicating cavity is provided inside the lubrication table, and the communicating cavity is connected to the fluid supply system; the scraper / cleaner is mounted on the lubrication table, a nozzle is provided on the scraper / cleaner, and the scraper / cleaner communicates with the communicating cavity.

[0006] The scraping component includes a scraper, a connecting cylinder, and an elastic element. The scraper is provided with a "V"-shaped scraping groove, which is adapted to the blade of the cutting knife. The nozzle is provided on the scraping groove. The connecting cylinder is installed on the scraper and is slidably installed on the lubrication table. The connecting cylinder is connected to the communicating cavity. The elastic element is sleeved on the connecting cylinder and connects the scraper and the lubrication table.

[0007] A rotating wiping plate and a detection mechanism are sequentially installed on the lubrication platform on one side of the scraper. The detection mechanism detects the cutting blade. The rotating wiping plate is oriented to match the cutting blade. A wiping component is installed on the rotating wiping plate. The rotating wiping plate and the wiping component are connected by a snap-fit ​​mechanism.

[0008] A drive element and a detection mechanism are sequentially installed on the lubrication platform on one side of the scraper. The detection mechanism detects the cutting blade. A rotating wiping plate is installed on the output end of the drive element. The orientation of the rotating wiping plate is adapted to the cutting blade. A wiping component is installed on the rotating wiping plate. The rotating wiping plate and the wiping component are connected by a snap-fit.

[0009] The wiping component is provided with a plurality of brush plates, which are arranged along the circumference of the wiping component.

[0010] The scrubbing component has a multi-layer composite structure, which includes, from the inside out, an installation base layer, a flexible scraping layer and a water-absorbing and drying layer. The scrubbing component is detachably connected to the rotating scrubbing plate through a snap-fit ​​structure.

[0011] The cutting unit also includes a positioning cylinder and several feeding rollers; the positioning cylinder is mounted on the shearing table, and the several feeding rollers are mounted on the shearing table below the positioning cylinder.

[0012] It also includes a grinding unit, which includes a lifting mechanism, a grinding motor, and a grinding plate. The lifting mechanism is installed on the shearing table, and a lifting frame is installed on the output end of the lifting mechanism. The grinding motor is installed on the lifting frame, and a reciprocating lead screw is connected to the output end of the grinding motor. The two ends of the reciprocating lead screw are rotatably installed on the lifting frame. The grinding plate is driven by the reciprocating lead screw and is slidably installed on the lifting frame via a guide rail.

[0013] The grinding plate has an "L" shaped cross section, grinding particles are provided on the grinding plate, and a heating element is provided on the grinding plate. The heating element is electrically connected to the control system.

[0014] During grinding operations, the L-shaped grinding plate can simultaneously cover the end face and upper and lower edges of the cut edge of the sheet metal, completing the grinding and edge blunting in one go. This eliminates burrs and prevents sharp edges from causing scratches to personnel during subsequent assembly and transportation, while also improving the assembly compatibility of the internal combustion engine sheet metal. The control system can control the heating element to generate heat according to the material and processing requirements of the sheet metal. The heat is evenly conducted to the cut edge of the sheet metal through the grinding plate, and the cut edge is subjected to low-temperature tempering treatment, which effectively eliminates the internal stress generated by the shearing process, improves the metallographic structure of the material at the cut edge, and enhances the fatigue resistance and structural strength of the internal combustion engine sheet metal.

[0015] The heating element and grinding plate are integrated, eliminating the need for a separate heat treatment station. Stress relief is completed simultaneously during the grinding process, significantly shortening the processing time of the sheet metal. The heating temperature is precisely controlled by the control system, making it suitable for various materials such as carbon steel, alloy steel, and stainless steel for internal combustion engine sheet metal, thus broadening the equipment's applicability.

[0016] The drive unit includes a drive source, a crankshaft, a connecting rod, and a tool holder. The drive source is mounted on a shearing table, and its output end is connected to the crankshaft, which is rotatably mounted on the shearing table. One end of the connecting rod is mounted on the crankshaft, and the other end is connected to the tool holder. The tool holder is slidably mounted on the shearing table, which restricts its movement to linear motion only. The cutting blade is mounted on the tool holder, and a lower cutting blade is provided on the shearing table below the cutting blade. A pressure claw is mounted on the tool holder.

[0017] During shearing operations, the drive source outputs rotational power, causing the crankshaft to rotate at a constant speed. The rotational motion of the crankshaft is converted into the vertical reciprocating motion of the blade holder through the connecting rod. During the downward movement of the blade holder, the pressure claw first contacts the sheet material to be processed, pressing and fixing the sheet material onto the shearing table. Then, the cutting blade moves downward and forms a shearing engagement with the lower cutting blade to complete the shearing process of the sheet material. During the upward return movement of the blade holder, the pressure claw rises synchronously, releasing the pressure constraint on the sheet material so that it can be fed and transported for the next time.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The cleaning effect can be adjusted according to different levels of impurities or debris. The scraper is elastically connected to the lubrication table via an elastic element, and a detection element monitors the scraper displacement in real time. When stubborn adhesive on the cutting blade surface causes excessive scraping resistance, the connecting cylinder retracts against the elastic force. Once the detection element detects that the displacement has reached a threshold, it triggers the liquid supply system to spray lubricating fluid from the scraper nozzle onto the cutting blade surface through the connecting cavity and the internal flow channel of the connecting cylinder. This impacts and wets the stubborn adhesive, reducing scraping resistance. After the resistance decreases, the elastic element pushes the scraper to extend back to its original position, the liquid supply automatically stops, and the dry scraping mode is restored. This achieves adaptive switching between dry and wet cleaning modes according to the actual contamination level of the blade surface, ensuring thorough removal of stubborn dirt, preventing scraper jamming and blade damage, and maximizing lubricating fluid consumption. The entire process requires no manual intervention.

[0019] 2. The cutting blade is wiped clean by a rotating wiping plate to remove residual debris and a thin layer of oil. A rotating wiping plate and a detection mechanism are sequentially installed on the lubrication platform behind the scraper. As the moving mechanism drives the lubrication platform along the slide rail, the scraper first performs a rough scraping of the blade surface to remove most of the dirt. Then, the wiping components on the rotating wiping plate perform a secondary wiping of the blade surface to remove residual debris and a thin layer of oil. Finally, the detection mechanism scans the entire blade body and cutting edge to determine if there are defects such as chipping, curling, or excessive wear. An early warning is issued if any abnormality is detected. This integrated "rough scraping-fine wiping-detection" operation significantly improves blade surface cleanliness and allows for timely detection of tool damage, preventing the continued use of defective tools that could lead to a decrease in shearing precision.

[0022] 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.

[0023] like Figures 1-7 As shown in the figure, Embodiment 1 of the present invention provides a shearing device for internal combustion engine production and processing.

[0024] The specific content of Embodiment 1 is as follows: A shearing equipment for internal combustion engine production and processing includes a fluid supply system, a shearing table 1, a cutting unit 2, and a lubrication and cleaning unit 3; the cutting unit 2 includes a drive unit 21 and a cutting blade 22, the drive unit 21 is mounted on the shearing table 1, and the output end of the drive unit 21 is connected to the cutting blade 22; the lubrication and cleaning unit 3 includes a slide rail 31, a moving mechanism 32, and a lubricator / cleaner 33, the slide rail 31 is mounted on the shearing table 1, and the moving mechanism 32 is mounted on the slide rail 31; the lubrication and cleaning unit 3 includes a slide rail 31, a moving mechanism 32, and a lubricator / cleaner 33. The device 33 includes a lubrication platform 331 and a scraper 332. The lubrication platform 331 is slidably mounted on the slide rail 31 and is connected to the output end of the moving mechanism 32. A detection element is provided on the lubrication platform 331 at the position corresponding to the scraper 332. A connecting cavity 3311 is provided inside the lubrication platform 331 and is connected to the liquid supply system (not shown in the figure). The scraper 332 is mounted on the lubrication platform 331 and is provided with a nozzle. The scraper 332 is connected to the connecting cavity 3311. The scraping component 332 includes a scraper 3321, a connecting cylinder 3322, and an elastic element 3323. The scraper 3321 is provided with a "V"-shaped scraping groove, which is adapted to the blade of the cutting knife 22, and the nozzle is provided on the scraping groove. The connecting cylinder 3322 is installed on the scraper 3321 and is slidably installed on the lubrication table 331. The connecting cylinder 3322 is connected to the connecting cavity 3311. The elastic element 3323 is sleeved on the connecting cylinder 3322 and connects the scraper 3321 and the lubrication table 331.

[0025] The liquid supply system in this embodiment includes a liquid supply pump and a pipeline. The inlet of the liquid supply pump is connected to a storage tank through a pipeline. The storage tank contains lubricating fluid. The outlet of the liquid supply pump is connected to the connecting cavity 3311 through a corrugated pipe or a telescopic pipe. The liquid supply pump draws the lubricating fluid from the storage tank into the connecting cavity 3311. A sensor for monitoring the flow rate of the lubricating fluid is installed in the storage tank.

[0026] The detection element in this embodiment is a displacement sensor, which is installed on the lubrication table 331 and faces the scraper 3321. The displacement sensor is used to detect the displacement of the scraper 3321.

[0027] In this embodiment, the moving mechanism 32 is a linear module. The lubrication platform 331 is mounted on the slider of the linear module. The linear module drives the lubrication platform 331 to move. The lubrication platform 331 drives the scraper 3321 to move through the connecting cylinder 3322, so that the scraper 3321 scrapes off the debris or impurities on the cutting blade 22.

[0028] In this embodiment, the elastic element 3323 is a return spring. Under the preload of the return spring, the connecting cylinder 3322 is in the extended state.

[0029] In this embodiment, the connecting cylinder 3322 and the lubrication platform 331 form a sliding seal connection to prevent lubricant leakage.

[0030] After the shearing operation is completed, the drive unit 21 drives the cutting blade 22 to rise back to the initial position. At this time, the blade of the cutting blade 22 is aligned with the scraping groove, preparing the position for subsequent cleaning operations.

[0031] After the cleaning operation is started, the moving mechanism 32 drives the lubrication table 331 to move along the slide rail 31. Under the pre-tightening force of the elastic element 3323, the connecting cylinder 3322 is in the extended state. The lubrication table 331 drives the scraper 3321 to move through the connecting cylinder 3322. The scraping groove on the scraper 3321 contacts the two sides of the cutting blade 22 to scrape off the debris on both sides of the cutting blade 22.

[0032] When there are few debris and low resistance on the surface of the cutting blade 22, the reaction force on the scraper 3321 is less than the preload of the elastic element 3323, and the connecting cylinder 3322 basically does not retract. The detection element on the lubrication table 331 collects the displacement data of the scraper 3321 in real time and feeds the displacement data back to the control system. At this time, the detection element detects that the displacement value is less than the preset threshold, and the liquid supply system does not work.

[0033] When there are adhesive debris, oxide scale, or oil deposits on the surface of the cutting blade 22, the resistance encountered by the scraper 3321 when scraping these areas increases sharply. The reaction force overcomes the elastic force of the elastic element 3323, pushing the connecting cylinder 3322 back into the lubrication table 331, and the displacement of the scraper 3321 increases accordingly. After the detection element detects that the displacement value reaches the preset threshold, it sends a signal to the control system, and the liquid supply system starts to work. The lubricant is sent from the liquid supply system into the communicating cavity 3311 inside the lubrication table 331. The connecting cylinder 3322 is connected to the communicating cavity 3311 and has an axial flow channel inside the rod. The lubricant flows directly into the scraper 3321 along the internal channel of the connecting cylinder 3322, and finally sprays onto the surface of the cutting blade 22 from the nozzle on the scraper 3321. The sprayed lubricant impacts the stubborn adhesive, reduces the scraping resistance of the scraper 3321, and prevents the scraper 3321 from jamming or chipping. At the same time, a liquid film is formed on the surface of the cutting blade 22, which plays a role in lubrication, rust prevention and cooling.

[0034] As the lubricant is continuously sprayed, stubborn debris is gradually washed away and removed. The resistance on the scraper 3321 gradually decreases, and the elastic force of the elastic element 3323 pushes the connecting cylinder 3322 outward, causing the scraper 3321 to return to its original position. When the detection element detects that the displacement value is lower than the threshold, the liquid supply system automatically stops supplying liquid, and the equipment resumes dry scraping mode. The entire process automatically switches according to the actual cleaning condition of the cutting blade 22 surface without manual intervention, ensuring both cleaning effect and saving lubricant consumption.

[0035] The cutting unit 2 also includes a positioning cylinder 23 and several feeding rollers 24; the positioning cylinder 23 is installed on the shearing table 1, and the several feeding rollers 24 are installed on the shearing table 1 below the positioning cylinder 23.

[0036] The feeding roller 24 is an electric roller, and an encoder is installed inside the feeding roller 24. A displacement sensor is installed on the shearing table 1. The displacement sensor and encoder monitor the displacement of the board in real time and feed the displacement data back to the control system.

[0037] Before starting work, the staff places one end of the board to be processed on the shearing table 1 and the other end on the feeding roller 24, so that the position of the board to be cut is directly opposite the cutting blade 22.

[0038] During operation, the telescopic rod of the positioning cylinder 23 moves downward to position the plate and prevent it from deforming during the cutting process.

[0039] After the cutting is completed, the positioning cylinder 23 retracts. At this time, the feeding roller 24 drives the plate to move forward so that the cut end of the plate is located between the two feeding rollers 24 and the end of the plate is facing the grinding unit. The positioning cylinder 23 extends again to position the plate. Then, the grinding unit starts to work and grinds the cut end of the plate.

[0040] like Figure 3 , Figures 5-7 As shown, in Embodiment 2 of the present invention, the design is further optimized based on Embodiment 1 by adding a rotating wiping plate 3324 and a detection mechanism to wipe and detect the cutting blade 22, thereby improving the cleaning effect of the cutting blade 22.

[0041] The drive unit 21 includes a drive source 211, a crankshaft 212, a connecting rod 213, and a tool holder 214. The drive source 211 is mounted on the shearing table 1, and its output end is connected to the crankshaft 212, which is rotatably mounted on the shearing table 1. One end of the connecting rod 213 is mounted on the crankshaft 212, and the other end is connected to the tool holder 214. The tool holder 214 is slidably mounted on the shearing table 1, which restricts its movement to linear motion. A cutting blade 22 is mounted on the tool holder 214, and a lower cutting blade is provided on the shearing table 1 below the cutting blade 22. A pressure claw 2141 is mounted on the tool holder 214, and it is slidably mounted on the tool holder 214 by a spring. The drive source 211 includes a drive motor, a belt, etc., and is used to drive the crankshaft 212 to rotate.

[0042] During the shearing operation, the drive source 211 outputs rotational power, driving the crankshaft 212 to rotate at a constant speed. The rotational motion of the crankshaft 212 is converted into the vertical reciprocating motion of the tool holder 214 through the connecting rod 213. During the downward movement of the tool holder 214, the pressure claw 2141 first contacts the plate to be processed, pressing and fixing the plate on the table surface of the shearing table 1. Then, the cutting blade 22 moves downward and forms a shearing engagement with the lower cutting blade to complete the shearing process of the plate. During the upward return of the tool holder 214, the pressure claw 2141 is raised synchronously to release the pressure constraint on the plate so that the plate can be fed and transported for the next time.

[0043] The specific content of Embodiment 2 is as follows: A rotating wiping plate 3324 and a detection mechanism are sequentially installed on the lubrication platform 331 on one side of the scraper 3321. The detection mechanism detects the cutting blade 22. The orientation of the rotating wiping plate 3324 is adapted to the cutting blade 22. A wiping component 33241 is installed on the rotating wiping plate 3324. The rotating wiping plate 3324 and the wiping component 33241 are connected by a snap-fit.

[0044] In this embodiment, the detection mechanism can be a displacement sensor, a distance sensor, or a vision sensor, used to detect the blade body and blade edge of the cutting blade 22 during the cleaning process, and to determine whether there are defects such as chipping, curling, or excessive wear on the blade edge.

[0045] In this embodiment, the rotating wiping plate 3324 is fixedly installed on the lubrication table 331.

[0046] During the cleaning operation, the moving mechanism 32 drives the lubrication table 331 to move along the slide rail 31. The scraper 3321 scrapes the surface of the cutting blade 22 to remove most of the iron filings, oxide scale, and adhering dirt. The rotating wiping plate 3324 moves synchronously with the lubrication table 331. The wiping part 33241 continuously contacts and rubs against the surface of the cutting blade 22, performing a secondary wiping of the fine dust and thin oil layer remaining after the scraper 3321 has removed the dirt, further improving the cleanliness of the blade surface. Finally, the detection mechanism moves with the lubrication table 331 and sweeps across the entire section of the cutting blade 22 to scan and detect the condition of the blade body and the integrity of the blade edge. If the detection of blade damage or wear exceeding the threshold is performed, an early warning signal is immediately sent to the control system to remind the operator to maintain the blade in time and avoid the blade defects from affecting the shearing accuracy.

[0047] The wiping component 33241 adopts a snap-on detachable connection. When the wiping component 33241 is worn, dirty or ineffective, it can be directly disassembled and replaced separately without replacing the entire rotating wiping plate 3324. It is easy to disassemble and assemble and has low maintenance costs.

[0048] like Figures 5-7As shown, Embodiment 3 of the present invention is a further optimized design based on Embodiment 1. The difference from Embodiment 2 is that the rotating wiping plate 3324 is equipped with a driving element, which can actively rotate to change from sliding wiping to rotating wiping, thereby improving the cleaning effect.

[0049] The specific content of this embodiment is as follows: A driving element (not shown in the figure) and a detection mechanism are sequentially installed on the lubrication table 331 on one side of the scraper 3321. The detection mechanism detects the cutting blade 22. A rotating wiping plate 3324 is installed on the output end of the driving element. The orientation of the rotating wiping plate 3324 is adapted to the cutting blade 22. A wiping component 33241 is installed on the rotating wiping plate 3324. The rotating wiping plate 3324 and the wiping component 33241 are connected by a snap-fit.

[0050] The testing agency may use displacement sensors, distance sensors or vision sensors to detect damage to the blade and body surface of the cutting knife 22.

[0051] After the cleaning operation is started, the moving mechanism 32 drives the lubrication table 331 to move along the slide rail 31. The scraper 3321 first performs a rough scraping on the surface of the cutting blade 22 to remove large pieces of debris and stubborn adhesive. The drive element starts simultaneously, driving the rotating wiping plate 3324 to rotate continuously around its own axis. The wiping part 33241 in the rotating state forms dynamic friction with the surface of the cutting blade 22. Compared with the fixed wiping plate, it can wipe the fine pits and dead corners of the blade surface more thoroughly, effectively removing residual micro-debris and thin oil film, and the cleaning effect is more thorough. After the wiping process is completed, the inspection mechanism moves with the lubrication table 331 to sweep across the entire cutting blade 22 to complete a comprehensive inspection of the blade condition.

[0052] Once the tool surface is found to be clean and free of defects, the drive element stops operating, and the moving mechanism 32 drives the lubrication table 331 back to its initial position, completing a full cleaning and inspection process.

[0053] like Figures 5-7 As shown, in Embodiment 4 of the present invention, the design is further optimized based on Embodiment 3, and a plurality of brush plates are provided on the scrubbing component 33241 to improve the scrubbing effect.

[0054] The specific content of Embodiment 4 is as follows: a plurality of brush plates are provided on the wiping component 33241, and the plurality of brush plates are arranged along the circumference of the wiping component 33241.

[0055] In this embodiment, the brush plate can be made of different materials such as nylon brushes and copper wire brushes according to cleaning needs, to adapt to different cleaning intensities and knife protection requirements.

[0056] When the driving element drives the rotating wiping plate 3324 to rotate, the circumferentially arranged brush plates rotate synchronously with the rotating wiping plate 3324. Multiple sets of brush plates sweep across the surface of the cutting blade 22 in sequence, forming a continuous brushing action. The bristles can penetrate deep into the micro-textures and blade edge gaps on the surface of the cutting blade 22, thoroughly sweeping out the small iron filings and dust hidden therein, making up for the inability of ordinary flat wiping plates to clean the gap structure. At the same time, multiple sets of brush plates alternately contact the blade surface, which can disperse the wear of a single set of brushes and extend the overall service life of the wiping part 33241.

[0057] For different knife materials and cleaning scenarios, the 33241 cleaning part can be replaced with brushes of different hardness and materials to ensure cleaning effect while avoiding damage to the knife edge and surface finish.

[0058] like Figure 7 As shown, Embodiment 5 of the present invention further optimizes the design based on Embodiments 2, 3 and 4, and provides a structure for a wiping component 33241 to improve the liquid absorption and drying capabilities of the wiping component 33241.

[0059] The specific content of Example 5 is as follows: The wiping component 33241 is a multi-layer composite structure, which includes, from the inside to the outside, an installation base layer, a flexible wiping layer and a water-absorbing and drying layer. The wiping component 33241 is detachably connected to the rotating wiping plate 3324 through a snap-fit ​​structure.

[0060] The flexible scraping layer is made of rubber or flexible silicone, which has elasticity and scraping toughness. It is mainly used to scrape off the thin oil and fine debris remaining on the blade surface. The water-absorbing and drying layer is made of high-density water-absorbing sponge or microfiber, which has good liquid absorption and drying capabilities.

[0061] When the rotating wiping plate 3324 moves or rotates the wiping component 33241, the flexible scraping layer first contacts the surface of the cutting blade 22 to gently scrape away the dirt remaining on the blade surface, avoiding damage to the surface smoothness and cutting edge precision of the blade by hard scraping; the water-absorbing and drying layer that follows quickly absorbs and dries the lubricating liquid and cleaning liquid remaining on the blade surface, keeping the surface of the cleaned cutting blade 22 dry, avoiding residual liquid from causing the blade to oxidize and rust, and preventing liquid droplets from contaminating the shearing table 1 and the internal combustion engine plate to be processed.

[0062] The multi-layer composite cleaning component 33241 has a clear division of functions for each layer, and can complete the two processes of scraping dirt and drying in one wiping, improving the efficiency of cleaning operations and the final cleaning effect; at the same time, the snap-on structure enables quick disassembly and assembly, making replacement and maintenance convenient.

[0063] like Figure 8As shown, Embodiment Six of the present invention further optimizes the design based on Embodiment One, and provides a grinding unit to grind the cut board material, thereby improving the processing quality of the board material cut.

[0064] The specific content of Embodiment Six is ​​as follows: It also includes a grinding unit, which includes a lifting mechanism 25, a grinding motor 251, and a grinding plate 252. The lifting mechanism 25 is installed on the shearing table 1, and a lifting frame is installed on the output end of the lifting mechanism 25. The grinding motor 251 is installed on the lifting frame, and a reciprocating lead screw 253 is connected to the output end of the grinding motor 251. Both ends of the reciprocating lead screw 253 are rotatably installed on the lifting frame. The grinding plate 252 is connected to the reciprocating lead screw 253 through a transmission, and the grinding plate 252 is slidably installed on the lifting frame through a guide rail.

[0065] After the grinding operation is started, the lifting mechanism 25 first drives the lifting frame to feed downwards, so that the grinding surface of the grinding plate 252 is aligned with the cut surface of the board. Then the grinding motor 251 is powered on and drives the reciprocating screw 253 to rotate continuously. Through the screw transmission pair, the rotational motion is converted into the linear reciprocating motion of the grinding plate 252 along the guide rail. The grinding plate 252 performs uniform reciprocating grinding on the cut surface of the board, and the burrs and flash at the cut are uniformly ground and removed.

[0066] The grinding structure driven by the reciprocating lead screw 253 can realize the automatic reciprocating operation of the grinding plate 252 without the need for an additional reversing mechanism. The overall structure is compact and the operation is stable and reliable. The reciprocating grinding can make the abrasive on the grinding plate 252 wear evenly, avoiding the problem of uneven grinding failure caused by continuous grinding on one side. At the same time, the reciprocating grinding method can obtain a smoother and more uniform cut surface, effectively improving the processing quality of the plate cut.

[0067] After grinding is completed, the grinding motor 251 drives the reciprocating lead screw 253 to rotate, so that the reciprocating lead screw 253 drives the grinding plate 252 back to its original position. Then, the lifting mechanism 25 drives the lifting frame and the grinding plate 252 to return to their original positions. Finally, the positioning cylinder 23 retracts and releases the plate, and the feeding roller 24 drives the ground plate to be discharged.

[0068] The grinding plate 252 has an "L" shaped cross section, grinding particles are provided on the grinding plate 252, and a heating element (not shown in the figure) is provided on the grinding plate 252. The heating element is electrically connected to the control system.

[0069] During the grinding operation, the L-shaped grinding plate 252 can simultaneously cover the end face and the upper and lower edges of the cut edge of the plate, completing the grinding and edge blunting treatment in one go. This eliminates burrs at the cut edge and avoids personnel scratches caused by sharp edges during subsequent assembly and transportation. It also improves the assembly adaptability of the internal combustion engine plate. The control system can control the heating element to generate heat according to the material and processing requirements of the plate. The heat is evenly conducted to the cut edge of the plate through the grinding plate 252, and the cut edge is subjected to low-temperature tempering treatment. This effectively eliminates the internal stress generated by the shearing process, improves the metallographic structure of the material at the cut edge, and enhances the fatigue resistance and structural strength of the internal combustion engine plate.

[0070] The heating element and the grinding plate 252 are integrated, eliminating the need for a separate heat treatment station. Stress relief is completed simultaneously during the grinding operation, significantly shortening the processing time of the sheet metal. The heating temperature is precisely controlled by the control system, making it suitable for various materials such as carbon steel, alloy steel, and stainless steel for internal combustion engine sheet metal, thus broadening the equipment's applicability.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
