Description

Technical Field

[0001] This invention belongs to the field of sheet metal stamping technology, specifically a long and narrow high-flanged sheet metal stamping die for new energy vehicles. Background Technology

[0002] Automotive sheet metal parts are important components in automobile manufacturing. Most existing automotive sheet metal parts are made by applying external force to sheet metal and profiles through presses and stamping dies to cause plastic deformation or separation, thereby obtaining sheet metal parts of the required shape and size. Due to the special shape of automobiles, sheet metal parts are mostly irregular shapes. For example, long and narrow sheet metal parts require the use of special stamping dies during stamping.

[0003] Existing stamping dies require the use of an air gun to clean the die head after stamping. However, most existing air guns are far from the die, so manual cleaning is still required, which is inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a long and narrow high-flanged stamping die for new energy vehicle sheet metal parts, comprising: a base, guide pillars evenly arranged on the top of the base, a lower die arranged on the outer wall of the guide pillars, and a movable plate arranged above the lower die;

[0005] This long, narrow, high-flanged stamping die for new energy vehicle sheet metal parts also includes:

[0006] A cleaning mechanism, the top of which is slidably connected to the bottom of a movable plate;

[0007] The cleaning mechanism includes a slider, the top of which is slidably connected to the bottom of a movable plate, a connecting rod rotatably connected to the bottom of the slider, a pneumatic assembly rotatably connected to the opposite side of the connecting rod, and an auxiliary assembly fixedly connected to the outer wall of the pneumatic assembly.

[0008] A protective mechanism, wherein the inner wall of the protective mechanism is slidably connected to the outer wall of the guide column;

[0009] The protective mechanism includes a fixed frame, the top of which is fixedly connected to the bottom of a movable plate. The inner wall of the fixed frame is slidably connected to the outer wall of a guide column. A folding plate is fixedly connected to the bottom of the fixed frame. Anti-scratch components are symmetrically arranged at the bottom of the fixed frame. The inner wall of the anti-scratch components is slidably connected to the outer wall of the guide column. A collection component is symmetrically arranged at the end of the fixed frame away from the folding plate. The outer wall of the collection component is rotatably connected to the outer wall of the fixed frame, enclosing the working space between the upper and lower molds to form a relatively closed space. This prevents debris from splashing during stamping and also prevents debris from being blown away during the cleaning mechanism's operation, making it difficult to collect and store. The anti-scratch components clean the debris adhering to the guide column. While cleaning the debris on the surface of the guide column, the movable plate moves downward, reducing debris between the movable plate and the guide column, keeping the guide column clean, and ensuring smoother sliding of the movable plate and the lower mold on the guide column. This ensures that the upper and lower molds do not jam during the mold closing process during stamping, thus maintaining the stamping equipment.

[0010] Furthermore, the bottom of the guide post is fixedly connected to the top of the base, the outer wall of the guide post is slidably connected to the inner wall of the lower mold, the outer wall of the guide post is slidably connected to the inner wall of the moving plate, and a hydraulic cylinder is fixedly connected to the top of the moving plate.

[0011] Furthermore, the cleaning mechanism also includes a fixed column, the top of which is fixedly connected to the bottom of the movable plate, and the bottom of which is fixedly connected to the upper mold. This reduces the amount of manual cleaning work, prevents people from getting close to the upper and lower molds and thus avoiding danger, thoroughly cleans the surface and interior of the lower mold, keeps the upper and lower molds clean, and allows for better stamping of sheet metal parts.

[0012] Furthermore, the pneumatic assembly includes a connecting rod, the bottom of which is rotatably connected to an air cylinder. The outer wall of the air cylinder is uniformly provided with nozzles, the outer wall of each nozzle is fixedly connected to the outer wall of the air cylinder. An air pipe is fixedly connected to the top of the air cylinder, and a rotating box is provided on the outer wall of the air pipe. The bottom of the rotating box is rotatably connected to the top of the upper mold. A partition is fixedly connected to the inner wall of the rotating box. The air pipe contacts the inner wall of the rotating box, and a connecting pipe is fixedly connected to the top of the air pipe. An air pump is fixedly connected to the end of the connecting pipe away from the rotating box, and the bottom of the air pump is fixedly connected to the top of the moving plate. This blows debris from the center of the groove to both ends. Because the groove of the lower mold is deep, blowing alone cannot completely blow out the debris. After the debris is blown to the edge of the groove, the air cylinder rotates, causing the auxiliary assembly to clean out the remaining debris and ultimately blow all the debris into the collection assembly, thus cleaning the debris inside the lower mold and maintaining the cleanliness of the surfaces of the lower and upper molds during stamping.

[0013] Furthermore, the auxiliary component includes a scraper blade, the outer wall of which is fixedly connected to the outer wall of the air cylinder. Elastic columns are evenly arranged at the bottom of the scraper blade, and the top of the elastic columns is rotatably connected to the bottom of the scraper blade. A scraping block is fixedly connected to the bottom of the elastic columns. Cleaning plates are symmetrically arranged on the outer wall of the scraper blade, and the outer wall of the scraper blade is rotatably connected to the outer wall of the cleaning plate. This prevents debris from being affected by airflow and returning to the lower mold, thus enhancing the overall cleaning of the lower mold and allowing debris to enter the collection component.

[0014] Furthermore, the anti-scratch component includes a housing, the top of which is fixedly connected to the bottom of the fixing frame. Extrusion rods are evenly arranged on the inner wall of the housing, the top of which is slidably connected to the inner wall of the housing. A cleaning block is fixedly connected to the bottom of the extrusion rod, and a fixing block is fixedly connected to the bottom of the cleaning block. The fixing block concentrates and accumulates debris between the cleaning block and the housing, causing debris in the gap between the bottom of the cleaning block and the housing to be gathered together under the rotation of the fixing block, allowing the nozzle to blow the debris to the collection component for collection.

[0015] Furthermore, the collecting assembly includes a cover plate, the top of which is rotatably connected to the outer wall of the fixed frame, and a rubber sheet fixedly connected to the bottom of the cover plate. One end of the rubber sheet near the guide post is fixedly connected to the outer wall of the lower mold. Side plates are symmetrically arranged at both ends of the cover plate, the inner walls of which are fixedly connected to the outer wall of the cover plate, and the ends of which are away from the cover plate are fixedly connected to the top of the rubber sheet. Rotating rods are symmetrically arranged on the inner wall of the cover plate, the outer walls of which are rotatably connected to the inner wall of the cover plate. A sleeve rod is slidably connected to the bottom of the rotating rod, and the outer wall of which is fixedly connected to the outer wall of the lower mold. A scraper is rotatably connected to the opposite side of the rotating rod. A collecting groove is fixedly connected to the bottom of the rubber sheet, and the outer wall of which is fixedly connected to the outer wall of the cover plate. When the distance between the moving plate and the lower mold increases, the cover plate and the rubber sheet are spread apart, maintaining isolation from the outside environment during stamping, protecting the health of surrounding workers, reducing the difficulty of cleaning up flying debris, and collecting the cleaned debris.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. Existing stamping dies require cleaning the die head with an air gun after stamping. However, most existing air guns are far from the die, still requiring manual cleaning, which is inconvenient. This invention, through the setting of a cleaning mechanism, pneumatic components and auxiliary components work together to gradually clean the debris inside and on the surface of the lower die to the side closer to the protective mechanism, and finally clean the debris into the collection component. This reduces the workload of manual cleaning, avoids the danger of people getting close to the upper and lower dies, thoroughly cleans the surface and inside of the lower die, keeps the upper and lower dies clean, and allows for better stamping of sheet metal parts.

[0018] 2. Due to the large impact force, metal shavings on the stamped sheet metal parts will be thrown around, affecting the working environment. This invention solves this problem by setting up a protective mechanism to enclose the working space between the upper and lower dies, forming a relatively closed space. This prevents shavings from flying around during stamping and also prevents shavings from being blown away by the cleaning mechanism, making them difficult to collect and store. The anti-scratch component cleans the shavings adhering to the guide post. While cleaning the shavings on the surface of the guide post, the moving plate moves downward, reducing debris between the moving plate and the guide post, keeping the guide post clean, and ensuring smoother sliding of the moving plate and the lower die on the guide post. This ensures that the upper and lower dies will not jam during the mold closing process during stamping, thus maintaining the stamping equipment.

[0019] 3. This invention uses a pneumatic component and an auxiliary component to blow debris from the middle of the groove to both ends. During blowing, the auxiliary component blocks the area that has already been blown over, preventing debris from splashing back into the groove. Since the groove of the lower mold is relatively deep, blowing alone cannot completely blow out the debris. After blowing the debris to the edge of the groove, the air cylinder rotates, causing the auxiliary component to clean out the remaining debris and finally blow all the debris into the collection component, thus cleaning the debris inside the lower mold and keeping the surfaces of the lower and upper molds clean during stamping.

[0020] 4. Due to the frequent reciprocating movement of the moving plate and the lower mold on the guide column, the surface of the guide column becomes magnetic and some debris adheres to it, which can easily affect the up and down movement of the moving plate. This invention solves this problem by setting an anti-scratch component and pressing the sleeve downwards with a rod to retract the cleaning block into the sleeve. Then the cleaning block continues to rotate, and the fixing block concentrates the debris between the cleaning block and the sleeve. The debris in the gap between the bottom of the cleaning block and the sleeve is concentrated together under the rotation of the fixing block, and the nozzle blows the debris to the collection component for collection.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0031] Example 1, please refer to Figures 1-4 The present invention provides a technical solution: a long and narrow high-flanged stamping die for new energy vehicle sheet metal parts, which is described below.

[0032] Includes: a base 1, guide columns 2 evenly arranged on the top of the base 1, a lower mold 3 arranged on the outer wall of the guide columns 2, a buffer device arranged at the bottom of the lower mold 3, and a movable plate 4 arranged above the lower mold 3;

[0033] This long, narrow, high-flanged stamping die for new energy vehicle sheet metal parts also includes:

[0034] The top of the cleaning mechanism 6 is slidably connected to the bottom of the movable plate 4, and two sets of the cleaning mechanism 6 are symmetrically arranged.

[0035] The inner wall of the protective mechanism 7 is slidably connected to the outer wall of the guide column 2, and two sets of the protective mechanism 7 are symmetrically arranged.

[0036] The bottom of the guide column 2 is fixedly connected to the top of the base 1, the outer wall of the guide column 2 is slidably connected to the inner wall of the lower mold 3, the outer wall of the guide column 2 is slidably connected to the inner wall of the moving plate 4, and a hydraulic cylinder 5 is fixedly connected to the top of the moving plate 4.

[0037] During operation, the sheet metal part is placed on the lower mold 3 and fixed in place, ready for stamping. The hydraulic cylinder 5 drives the upper mold 605 below the moving plate 4 to move downward, so that the upper and lower molds 3 close and the sheet metal part is stamped. After working for a period of time, metal debris remains in the groove of the lower mold 3. The cleaning component cleans out the debris from the surface and inside of the lower mold 3. The protective mechanism 7 surrounds the gap between the upper mold 605 and the lower mold 3 during stamping to prevent debris from being splashed out by the stamping pressure and injuring the workers. It also prevents debris from splashing when the cleaning mechanism 6 is working.

[0038] The cleaning mechanism 6 includes a slider 601, the top of which is slidably connected to the bottom of the movable plate 4. There are two sets of sliders 601, two in each set. The bottom of the slider 601 is rotatably connected to a connecting rod 6021. Initially, the connecting rod 6021 drives the pneumatic assembly 602 to be placed horizontally below the movable plate 4. The pneumatic assembly 602 is rotatably connected to the opposite side of the connecting rod 6021. An auxiliary assembly 603 is fixedly connected to the outer wall of the pneumatic assembly 602.

[0039] The cleaning mechanism 6 also includes a fixed column 604, the top of which is fixedly connected to the bottom of the movable plate 4, and the bottom of the fixed column 604 is fixedly connected to an upper mold 605, which fits into the groove of the lower mold 3.

[0040] After stamping, some metal debris will remain on the surface of the lower die 3. At this time, the slider 601 drives the connecting rod 6021 to rotate, placing the pneumatic component 602 inside the lower die 3. Driven by the slider 601, it moves from the middle of the upper die 605 to both sides. During the movement, the pneumatic component 602 and the auxiliary component 603 work together to gradually clean the debris inside and on the surface of the lower die 3 to the side close to the protective mechanism 7. Finally, the debris is cleaned into the collection component 704, reducing the amount of manual cleaning work and preventing people from getting close to the upper and lower dies 3, thus avoiding danger. The surface and interior of the lower die 3 are thoroughly cleaned, keeping the upper die 605 and the lower die 3 clean, so that the sheet metal parts can be stamped better.

[0041] The protective mechanism 7 includes a fixed frame 701, the top of which is fixedly connected to the bottom of the movable plate 4. The fixed frame 701 moves up and down with the movable plate 4 during use. The inner wall of the fixed frame 701 is slidably connected to the outer wall of the guide column 2. A folding plate 702 is fixedly connected to the bottom of the fixed frame 701. The folding plate 702 is made of breathable material. The folding plate 702 drives the bottom to engage with the top of the lower mold 3. When feeding, the folding plate 702 is opened for feeding. During the up and down movement of the movable plate 4, the folding plate 702 is bent by force. Anti-scratch components 703 are symmetrically arranged at the bottom of the fixed frame 701. The inner wall of the anti-scratch components 703 is slidably connected to the outer wall of the guide column 2. A collection component 704 is symmetrically arranged at the end of the fixed frame 701 away from the folding plate 702. The outer wall of the collection component 704 is rotatably connected to the outer wall of the fixed frame 701.

[0042] During stamping, the upper die 605 and the lower die 3 approach each other. Due to the large impact force, metal chips on the stamped sheet metal parts will be thrown around, affecting the working environment. The two sets of collecting components 704 and the folding plate 702 work together to enclose the working space between the upper die 605 and the lower die 3, forming a relatively closed space to prevent chips from flying around during stamping and to prevent chips from being blown away when the cleaning mechanism 6 is working, making them difficult to collect and store. The anti-scratch component 703 cleans the chips adhering to the guide post 2. While cleaning the chips on the surface of the guide post 2, the moving plate 4 moves downward to reduce debris between the moving plate 4 and the guide post 2, keeping the guide post 2 clean and also making the sliding of the moving plate 4 and the lower die 3 on the guide post 2 smoother. This ensures that the upper die 605 and the lower die 3 will not get stuck during the mold closing process during stamping, thus maintaining the stamping equipment.

[0043] Example 2, please refer to Figures 1-8The present invention provides a technical solution: Based on Embodiment 1, the pneumatic assembly 602 includes a connecting rod 6021, with an air cylinder 6022 rotatably connected to the bottom of the connecting rod 6021. The air cylinder 6022 is connected to an air pump 6028 via a connecting pipe 6027 and an air pipe 6024. Nozzles 6023 are evenly arranged on the outer wall of the air cylinder 6022, and the outer wall of the nozzles 6023 is fixedly connected to the outer wall of the air cylinder 6022. An air pipe 6024 is fixedly connected to the top of the air cylinder 6022. The air pipe 6024 is a flexible hose, and a rotating box 6025 is provided on the outer wall of the air pipe 6024. Excess air pipe 6024 is coiled in a rotating... Inside box 6025, when air tube 6024 is under tension, rotating box 6025 rotates, pulling air tube 6024 out of rotating box 6025. The bottom of rotating box 6025 is rotatably connected to the top of upper mold 605. A partition strip 6026 is fixedly connected to the inner wall of rotating box 6025. Air tube 6024 is in contact with the inner wall of rotating box 6025. A connecting pipe 6027 is fixedly connected to the top of air tube 6024. The connecting pipe 6027 is made of rigid plastic. An air pump 6028 is fixedly connected to the end of connecting pipe 6027 away from rotating box 6025. The bottom of air pump 6028 is fixedly connected to the top of moving plate 4.

[0044] Initially, the connecting rod 6021 drives the air cylinder 6022 to be positioned below the moving plate 4, and the connecting rod 6021 is placed horizontally. During cleaning, the air pump 6028 is turned on, and the two sets of connecting rods 6021 drive the two air cylinders 6022 to move to the middle of the upper mold 605. At this time, the nozzle 6023 blows air onto the upper mold 605, causing the debris on the surface of the upper mold 605 to be blown away. When it reaches the middle of the upper mold 605, the air cylinder 6022 rotates, so that the nozzle 6023 is aligned with the inside of the groove of the lower mold 3, and the bottom of the scraper 6031 contacts the inner wall of the groove and the bottom of the groove. At this time, the nozzle 6023 tilts and blows air onto the inner wall of the groove, blowing the debris from the middle of the groove to both ends. While blowing air, the auxiliary component 603 blocks the area that has already been blown to prevent the debris from splashing back into the groove. Since the groove of the lower mold 3 is relatively deep, blowing air alone cannot completely blow out the debris. After blowing the debris to the edge of the groove, the air cylinder 6022 rotates, causing the auxiliary component 603 to clean out the remaining debris and finally blow all the debris into the collection component 704, so that the debris inside the lower mold 3 is cleaned and the surfaces of the lower mold 3 and the upper mold 605 are kept clean during stamping.

[0045] The auxiliary component 603 includes a scraper 6031, which is T-shaped and has its bottom in contact with the groove of the lower mold 3. The outer wall of the scraper 6031 is fixedly connected to the outer wall of the air cylinder 6022. Elastic columns 6032 are evenly arranged at the bottom of the scraper 6031. The top of the elastic columns 6032 is rotatably connected to the bottom of the scraper 6031. A scraper block 6033 is fixedly connected to the bottom of the elastic columns 6032. Due to the gravity of the scraper block 6033, the elastic column 6032 always remains vertical. The bottom of the scraper block 6033 is in contact with the upper surface of the lower mold 3. A cleaning plate 6034 is symmetrically arranged on the outer wall of the scraper 6031. Initially, the cleaning plate 6034 is placed horizontally, and the outer wall of the scraper 6031 is rotatably connected to the outer wall of the cleaning plate 6034.

[0046] During cleaning, the bottom of the scraper 6031 contacts the bottom of the groove, the bottom of the scraper block 6033 contacts the upper surface of the lower mold 3, and the surface of the cleaning plate 6034 contacts the inner wall of the folding plate 702. As the air cylinder 6022 moves, it cleans the surface of the lower mold 3 and the inner wall of the folding plate 702, and blocks the airflow from the nozzle 6023 to prevent debris from being affected by the airflow and returning to the interior of the lower mold 3. This strengthens the overall cleaning of the lower mold 3 and allows the debris to enter the collection component 704.

[0047] The anti-scratch component 703 includes a housing 7031, the top of which is fixedly connected to the bottom of a fixing frame 701. The inner wall of the housing 7031 is evenly provided with extrusion rods 7032, the top of which is slidably connected to the inner wall of the housing 7031. The bottom of the extrusion rods 7032 is fixedly connected to a cleaning block 7033, the bottom of which is provided with a conical surface. The bottom of the cleaning block 7033 is fixedly connected to a fixing block 7034, which can be placed inside the housing 7031.

[0048] When the upper mold 605 and the lower mold 3 are closed, the moving plate 4 drives the fixed frame 701 to move downward. During the downward movement, the built-in drive of the housing 7031 drives the extrusion rod 7032 to rotate the cleaning block 7033. As the moving plate 4 and the lower mold 3 move back and forth on the guide post 2 frequently, the surface of the guide post 2 becomes magnetic and some debris adheres to it, which easily affects the up and down movement of the moving plate 4. The cleaning block 7033 pushes the debris on the surface of the guide post 2 downward, so that the debris eventually accumulates on the lower mold. The upper surface of the device 3 is then moved downwards, causing the housing 7031 to press down on the rod 7032, retracting the cleaning block 7033 into the housing 7031. The cleaning block 7033 then continues to rotate, and the fixing block 7034 concentrates the debris between the cleaning block 7033 and the housing 7031. The debris in the gap between the bottom of the cleaning block 7033 and the housing 7031 is concentrated together under the rotation of the fixing block 7034, and the nozzle 6023 blows the debris to the collection assembly 704 for collection.

[0049] The collecting assembly 704 includes a cover plate 7041. The top of the cover plate 7041 is rotatably connected to the outer wall of the fixing frame 701. A rubber sheet 7042 is fixedly connected to the bottom of the cover plate 7041. One end of the rubber sheet 7042 near the guide post 2 is fixedly connected to the outer wall of the lower mold 3. A groove is opened at the bottom of the rubber sheet 7042, corresponding to the collecting groove 7047. Side plates 7043 are symmetrically arranged at both ends of the cover plate 7041. The side plates 7043 are made of a flexible material with elasticity. The inner wall of the side plate 7043 is fixedly connected to the outer wall of the cover plate 7041. The end of the side plate 7043 away from the cover plate 7041 is connected to the rubber sheet 7042. The top of 042 is fixedly connected. The inner wall of the cover plate 7041 is symmetrically provided with rotating rods 7044. The outer wall of the rotating rods 7044 is rotatably connected to the inner wall of the cover plate 7041. The bottom of the rotating rods 7044 is slidably connected to the sleeve rod 7045. The outer wall of the sleeve rod 7045 is fixedly connected to the outer wall of the lower mold 3. The bottom of the rotating rods 7044 moves back and forth in the sleeve rod 7045. The opposite side of the rotating rods 7044 is rotatably connected to the scraper 7046. The scraper 7046 remains vertical. The bottom of the rubber sheet 7042 is fixedly connected to the collection groove 7047. The outer wall of the collection groove 7047 is fixedly connected to the outer wall of the cover plate 7041.

[0050] The cover plate 7041 is not equipped with an additional drive. When the moving plate 4 moves up and down, the cover plate 7041 also moves, thereby driving the rotating rod 7044 to move along the sleeve rod 7045, which in turn drives the scraper 7046 to clean the debris on the top of the rubber sheet 7042 into the collection groove 7047. When the distance between the moving plate 4 and the lower mold 3 increases, the cover plate 7041 and the rubber sheet 7042 are spread apart, keeping them isolated from the outside world during the stamping process, protecting the health of the surrounding workers, reducing the difficulty of cleaning up flying debris, and collecting the cleaned debris.

[0051] The specific workflow is as follows:

[0052] After the sheet metal part is placed on the lower mold 3 and fixed, the hydraulic cylinder 5 drives the upper mold 605 below the moving plate 4 to move downward, so that the upper and lower molds 3 close and the sheet metal part is stamped. After working for a period of time, metal chips remain in the groove of the lower mold 3. Due to the large impact force, the metal chips on the stamped sheet metal part will be thrown by force, affecting the working environment. The two sets of collecting components 704 and the folding plate 702 work together to enclose the working space between the upper mold 605 and the lower mold 3, forming a relatively closed space to avoid the flying of chips during stamping.

[0053] After stamping, some metal debris will remain on the surface of the lower die 3. At this time, the slider 601 drives the connecting rod 6021 to rotate, placing the pneumatic component 602 inside the lower die 3. Driven by the slider 601, it moves from the middle of the upper die 605 to both sides. During the movement, the pneumatic component 602 and the auxiliary component 603 cooperate to gradually clean the debris inside and on the surface of the lower die 3 to the side close to the protective mechanism 7. Finally, the debris is cleaned into the collection component 704, reducing the amount of manual cleaning work.

[0054] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
