[0002] Automotive sheet metal is an important component in automobile manufacturing. Most of the existing automotive sheet metal is obtained by applying external force to plates and profiles through presses and stamping dies to make them plastically deform or separate, thereby obtaining sheet metal parts of the required shape and size. However, due to the special appearance of automobiles, sheet metal parts are mostly irregular in shape. For example, long and narrow sheet metal parts require special stamping dies during stamping.

[0015] The top of the cover plate is rotatably connected to the outer wall of the fixed frame, and the bottom of the cover plate is fixedly connected to a rubber sheet, and one end of the rubber sheet close to the guide column is fixedly connected to the outer wall of the lower mold, and the two ends of the cover plate are symmetrically provided with side plates, the inner wall of the side plate is fixedly connected to the outer wall of the cover plate, and the end of the side plate away from the cover plate is fixedly connected to the top of the rubber sheet, and the inner wall of the cover plate is symmetrically provided with a rotating rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the cover plate, and the bottom of the rotating rod is slidably connected to a sleeve rod, the outer wall of the sleeve rod is fixedly connected to the outer wall of the lower mold, and the opposite side of the rotating rod is rotatably connected to a scraper, and the bottom of the rubber sheet is fixedly connected to a collecting trough, and the outer wall of the collecting trough 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 stretched apart, so as to be isolated from the outside during stamping processing, protect the health of surrounding workers, reduce the splashing of debris and make it difficult to clean, and collect the cleaned debris.

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

[0017] 1. The existing stamping die needs to be cleaned with an air gun after stamping. However, most of the existing air guns are far away from the die and still need to be cleaned manually, which is inconvenient to use. The present invention sets a cleaning mechanism, and the pneumatic components and auxiliary components cooperate to gradually clean the debris inside and on the surface of the lower die to the side close to the protective mechanism, and finally clean the debris to the inside of the collecting component, thereby reducing the workload of manual cleaning and avoiding danger caused by human hands approaching the upper and lower dies. The surface and interior of the lower die are thoroughly cleaned, and the cleanliness between the upper and lower dies is maintained, so that the sheet metal parts can be better stamped.

[0018] 2. Due to the large impact force, metal debris on the stamped sheet metal parts will be splashed due to the force, affecting the working environment. The present invention sets a protective mechanism to enclose the working space between the upper mold and the lower mold to form a relatively closed space, so as to avoid the debris from splashing during stamping, and also avoid the debris from being blown away when the cleaning mechanism is working, which makes it difficult to collect and store. The anti-scratch component cleans the debris adhered to the guide column, and while the debris on the surface of the guide column is cleaned, the movable plate is moved downward to reduce the debris between the movable plate and the guide column, keep the guide column clean, and keep the movable plate and the lower mold sliding on the guide column more smoothly, ensuring that during the stamping work, the upper mold and the lower mold will not get stuck during the mold closing process, thereby maintaining the stamping equipment.

[0019] 3. The present invention sets a pneumatic component and an auxiliary component to blow the debris from the middle of the groove to both ends. When blowing, the auxiliary component blocks the position that has been blown to prevent the debris from splashing back into the groove. Since the groove of the lower mold is deeper, the debris cannot be completely blown out by blowing alone. After the debris is blown to the edge of the groove, the air cylinder rotates to allow the auxiliary component to clean up the remaining debris and finally blow all the debris into the collecting component, so that the debris inside the lower mold is cleaned and the surfaces of the lower mold and the upper mold are kept clean during stamping.

[0020] 4. Since the movable plate and the lower mold frequently move back and forth on the guide column, the surface of the guide column has a certain magnetism and some debris is attached, which can easily affect the up and down movement of the movable plate. The present invention sets an anti-scratch component, and the casing squeezes the rod downward to retract the cleaning block into the casing. Then the cleaning block continues to rotate, and the fixed block concentrates and accumulates the debris between the cleaning block and the casing. The debris in the gap between the bottom of the cleaning block and the casing is concentrated together under the rotation of the fixed block, so that the nozzle blows the debris to the collecting component for collection.

At this time, the slider 601 drives the connecting rod 6021 to rotate, and the pneumatic component 602 is placed inside the lower mold 3. Driven by the slider 601, it moves from the middle of the upper mold 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 mold 3 to the side close to the protective mechanism 7, and finally clean the debris to the inside of the collecting component 704, reducing the workload of manual cleaning and avoiding danger caused by human hands approaching the upper and lower molds 3. The surface and interior of the lower mold 3 are thoroughly cleaned to keep the upper mold 605 and the lower mold 3 clean, so that the sheet metal parts can be better stamped.

[0041] The protective mechanism 7 includes a fixed frame 701, the top of the fixed frame 701 is fixedly connected to the bottom of the movable plate 4, the fixed frame 701 moves up and down with the movable plate 4 when in use, the inner wall of the fixed frame 701 is slidably connected to the outer wall of the guide column 2, and the bottom of the fixed frame 701 is fixedly connected with a folding plate 702, the folding plate 702 is made of breathable material, the folding plate 702 drives the bottom and the top of the lower mold 3 to be clamped, and the folding plate 702 is opened for loading during feeding. In the process of the movable plate 4 moving up and down, the folding plate 702 is bent by force, and the bottom of the fixed frame 701 is symmetrically provided with an anti-scratch component 703, the inner wall of the anti-scratch component 703 is slidably connected to the outer wall of the guide column 2, and the end of the fixed frame 701 away from the folding plate 702 is symmetrically provided with a collecting component 704, and the outer wall of the collecting component 704 is rotatably connected to the outer wall of the fixed frame 701.

[0042] During stamping, the upper mold 605 and the lower mold 3 are close to each other. Due to the large impact force, the metal debris on the stamped sheet metal will be splashed due to the force, affecting the working environment. The two sets of collecting components 704 and the folding plate 702 cooperate with each other to enclose the working space between the upper mold 605 and the lower mold 3 to form a relatively closed space, so as to avoid the debris from splashing during stamping, and also avoid the debris from being blown away when the cleaning mechanism 6 is working, which makes it difficult to collect and store. The anti-scratch component 703 cleans the debris adhered to the guide column 2, so that the debris on the surface of the guide column 2 is cleaned, and then the movable plate 4 is moved downward to reduce the debris between the movable plate 4 and the guide column 2, keep the guide column 2 clean, and keep the movable plate 4 and the lower mold 3 sliding on the guide column 2 more smoothly, ensuring that during stamping, the upper mold 605 and the lower mold 3 will not get stuck during the mold closing process, thereby maintaining the stamping equipment.

[0043] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the pneumatic assembly 602 includes a connecting rod 6021, the bottom of the connecting rod 6021 is rotatably connected to a cylinder 6022, the cylinder 6022 is connected to an air pump 6028 through a connecting pipe 6027 and an air pipe 6024, the outer wall of the cylinder 6022 is evenly provided with nozzles 6023, the outer wall of the nozzle 6023 is fixedly connected to the outer wall of the cylinder 6022, the top of the cylinder 6022 is fixedly connected to an air pipe 6024, the air pipe 6024 is a hose, the outer wall of the air pipe 6024 is provided with a rotating box 6025, and the redundant air pipes 6024 are on the rotating disk Inside the box 6025, when the air pipe 6024 is subjected to tension, the rotating box 6025 rotates, and the air pipe 6024 is pulled out of the rotating box 6025. The bottom of the rotating box 6025 is rotatably connected to the top of the upper mold 605. The inner wall of the rotating box 6025 is fixedly connected with a partition bar 6026. The air pipe 6024 contacts the inner wall of the rotating box 6025. The top of the air pipe 6024 is fixedly connected with a connecting pipe 6027. The connecting pipe 6027 is made of a hard plastic pipe. The end of the connecting pipe 6027 away from the rotating box 6025 is fixedly connected with an air pump 6028. The bottom of the air pump 6028 is fixedly connected to the top of the movable plate 4.

[0044] Initially, the connecting rod 6021 drives the air cylinder 6022 to be located below the movable plate 4, and the connecting rod 6021 is placed horizontally. When 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 to the upper mold 605 to blow away the debris on the surface of the upper mold 605. When reaching the middle of the upper mold 605, the air cylinder 6022 rotates to align the nozzle 6023 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 contacts the bottom of the groove. At this time, the nozzle 6023 blows air at an angle to the inner wall of the groove, blowing the debris from the middle of the groove to both ends. When blowing, the auxiliary component 603 blocks the position that has been blown to prevent the debris from splashing back into the groove. Since the groove of the lower mold 3 is deeper, the debris cannot be completely blown out by blowing alone. After the debris is blown to the edge of the groove, the air cylinder 6022 rotates to allow the auxiliary component 603 to clean up the remaining debris, and finally blow all the debris into the collecting component 704, so that the debris inside the lower mold 3 is cleaned and the surface 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 a bottom that contacts 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 column 6032 is rotatably connected to the bottom of the scraper 6031. A scraper block 6033 is fixedly connected to the bottom of the elastic column 6032. Affected by the gravity of the scraper block 6033, the elastic column 6032 always maintains a vertical state. The bottom of the scraper block 6033 contacts the upper surface of the lower mold 3. The outer wall of the scraper 6031 is symmetrically provided with a cleaning plate 6034. 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, the surface of the lower mold 3 and the inner wall of the folding plate 702 are cleaned, and the airflow sprayed from the nozzle 6023 is blocked to prevent debris from being affected by the airflow and returning to the lower mold 3, thereby strengthening the overall cleaning of the lower mold 3 and allowing the debris to enter the collection component 704.

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

[0048] When the upper mold 605 and the lower mold 3 are molded together, the movable plate 4 drives the fixed frame 701 to move downward, and in the process of moving downward, the built-in drive of the sleeve 7031 drives the extrusion rod 7032 to drive the cleaning block 7033 to rotate. Since the movable plate 4 and the lower mold 3 frequently move back and forth on the guide column 2, the surface of the guide column 2 has a certain magnetism, and some debris is attached, which is easy to affect the upward and downward movement of the movable plate 4. The cleaning block 7033 pushes the debris on the surface of the guide column 2 downward, so that the debris is finally accumulated on the lower mold. The upper surface of the tool 3 is then moved downwardly, so that the sleeve 7031 squeezes the rod 7032 downwardly, and the cleaning block 7033 is retracted into the sleeve 7031. The cleaning block 7033 then continues to rotate, and the fixed block 7034 concentrates the debris between the cleaning block 7033 and the sleeve 7031, so that the debris in the gap between the bottom of the cleaning block 7033 and the sleeve 7031 is concentrated together under the rotation of the fixed block 7034, and the nozzle 6023 blows the debris to the collection component 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, the bottom of the cover plate 7041 is fixedly connected to a rubber sheet 7042, the end of the rubber sheet 7042 close to the guide column 2 is fixedly connected to the outer wall of the lower mold 3, the bottom of the rubber sheet 7042 is provided with a notch corresponding to the collecting groove 7047, the two ends of the cover plate 7041 are symmetrically provided with side plates 7043, the side plates 7043 are made of elastic and flexible material, the inner wall of the side plate 7043 is fixedly connected to the outer wall of the cover plate 7041, and the end of the side plate 7043 away from the cover plate 7041 is fixedly connected to the rubber sheet 7 The top of the rubber sheet 7042 is fixedly connected, the inner wall of the cover plate 7041 is symmetrically provided with a rotating rod 7044, the outer wall of the rotating rod 7044 is rotatably connected to the inner wall of the cover plate 7041, the bottom of the rotating rod 7044 is slidably connected with a 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 rod 7044 moves back and forth in the sleeve rod 7045, the opposite side of the rotating rod 7044 is rotatably connected with a scraper 7046, the scraper 7046 remains vertical, the bottom of the rubber sheet 7042 is fixedly connected with a collecting trough 7047, and the outer wall of the collecting trough 7047 is fixedly connected to the outer wall of the cover plate 7041.

[0050] The cover plate 7041 is not provided with an additional drive. When the movable plate 4 moves up and down, the cover plate 7041 also moves therewith, thereby driving the rotating rod 7044 to move along the sleeve rod 7045, and then driving 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 movable plate 4 and the lower mold 3 increases, the cover plate 7041 and the rubber sheet 7042 are stretched apart to keep it isolated from the outside world during the stamping process, protect the health of the surrounding workers, reduce the splashing of debris that is difficult to clean, and collect the cleaned debris.

[0051] The specific workflow is as follows:

[0052] After placing the sheet metal on the lower mold 3 and fixing it, the hydraulic cylinder 5 drives the upper mold 605 under the movable plate 4 to move downward, so that the upper and lower molds 3 are closed and the sheet metal is stamped into shape. After working for a period of time, metal debris remains in the groove of the lower mold 3. Due to the large impact force, the metal debris on the stamped sheet metal will be splashed, affecting the working environment. The two sets of collecting components 704 and the folding plate 702 cooperate with each other to enclose the working space between the upper mold 605 and the lower mold 3 to form a relatively closed space to avoid debris splashing during stamping.

[0053] After the stamping is completed, a certain amount of metal debris will remain on the surface of the lower mold 3. At this time, the slider 601 drives the connecting rod 6021 to rotate, and the pneumatic component 602 is placed inside the lower mold 3. Driven by the slider 601, it moves from the middle of the upper mold 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 mold 3 to the side close to the protective mechanism 7, and finally clean the debris to the inside of the collection component 704, reducing the workload of manual cleaning.

[0054] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
