TECHNICAL FIELD

[0003] The prior art also proposes some solutions for stamping of automobile support, such as applying high pressure to metal sheet through die to make it plastic deformation, forming high-precision, high-strength and lightweight support parts, and its core structure includes rack, slider, workbench, transmission system and die system, which generates stamping force through motor-driven crank mechanism or hydraulic cylinder to close the upper and lower dies to complete blanking, bending, stretching and other processes.

[0004] In the above-mentioned stamping machine, the plate will continuously rub against the die during continuous stamping, which will cause wear or scratches on the surface of the die, affecting the service life of the die.

[0020] 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.

[0021] like Figures 1 to 4As shown in the embodiment of the present invention, an automotive bracket stamping machine includes a worktable 1; a die 2 is mounted on the top surface of the worktable 1; a top block 3 is slidably connected inside the die 2, and the top block 3 is driven by a hydraulic rod; two pairs of symmetrically arranged guide pillars 4 are fixedly connected to the top surface of the worktable 1; a pressure plate 5 is slidably connected to the surface of the guide pillars 4; a punch 6 is mounted on the bottom surface of the pressure plate 5; a hydraulic cylinder 7 is fixedly connected to the top surface of the guide pillars 4; the telescopic end of the hydraulic cylinder 7 is fixedly connected to the top surface of the pressure plate 5; the top surface of the worktable 1... Guide rails 8 are fixedly connected to both sides of the die 2; a support frame 9 is slidably connected between the two guide rails 8, and the support frame 9 is driven by a servo motor; a movable seat 10 is slidably connected to the top of the support frame 9, and the movable seat 10 is driven by a PLC through a servo motor; multiple evenly arranged oil mist lubricators 11 are fixedly connected to the top and bottom surfaces of the movable seat 10; during operation, in order to reduce the wear of the die on continuous stamping, the embodiment of the present invention can be used. During normal stamping, the material to be stamped is placed at the die 2, and then the hydraulic cylinder 7 drives... The moving pressure plate 5 descends, which in turn moves the punch 6 towards the worktable 1, squeezing the material at the die 2, thus completing the stamping operation. Afterwards, the hydraulic cylinder 7 raises the pressure plate 5 and the punch 6, causing the ejector block 3 at the die 2 to push out, thereby ejecting the stamped car bracket from the die 2, completing the entire stamping operation. To reduce wear on the punch 6 and the die 2 and extend their service life, after multiple stamping operations, the support frame 9 slides along the guide rail 8, causing the moving seat 10 on it to pass completely between the punch 6 and the die 2. On the surface, during this process, the servo motor drives the moving seat 10 to slide on the surface of the support frame 9, thereby driving the oil mist sprayer 11 to sweep across the protrusion of the punch 6 and the top block 3 of the die 2. During this process, the oil mist sprayer 11 will spray lubricating oil mist, so that a layer of oil film is evenly adhered to the protrusion of the punch 6 and the top block 3 of the die 2, thereby reducing the friction in the subsequent stamping process, thereby reducing the life of the punch 6 and the die 2, extending their service life, and at the same time controlling the amount of lubricating oil used, ensuring lubrication while reducing the amount of lubricating oil used.

[0022] like Figures 4 to 5As shown, a pair of symmetrically arranged pressure rods 12 are installed on the top and bottom of the movable seat 10 on one side of the oil mist sprayer 11; a sleeve 13 is slidably connected to the side of the pressure rod 12 away from the movable seat 10; a spring 14 is fixedly connected between the sleeve 13 and the pressure rod 12; a sponge 15 is fixedly connected to the end of the pair of sleeves 13 away from the pressure rod 12; during operation, as the oil mist sprayer 11 sprays oil mist onto the surfaces of the die 2 and the punch 6, the movement of the support frame 9 and the movable seat 10 will also synchronously drive the pressure rod 12 and the sleeve 13 to move synchronously, thereby driving the sponge 15 to move synchronously, thus achieving the application of lubricating oil, so that the lubricating oil can be applied more evenly to the punch 6 and the die 2, and the spring 14 between the pressure rod 12 and the sleeve 13 can ensure the pressure of the sponge 15 on the punch 6 and the die 2, further improving the application effect of the lubricating oil.

[0023] like Figures 2 to 6 As shown, a connecting ring 16 is fixedly connected between the top and bottom pairs of pressure rods 12; the connecting ring 16 is rotatably connected to the movable seat 10; gear 17 is fixedly connected to the side of each of the two connecting rings 16 that is far apart from each other; bases 18 are fixedly connected to the top surface of the worktable 1 at both ends of the die 2; gear 29 is rotatably connected to the top of the base 18, and gear 29 is driven by servo motor 3, and gear 29 can mesh with gear 17; a pair of symmetrically arranged magnet posts 20 are fixedly connected to the side of each of the two connecting rings 16 that is close to each other, and the side of the two magnet posts 20 that is close to each other is arc-shaped; a magnet block 21 is fixedly connected to the top surface of the movable seat 10; the magnet posts 20 and the magnet block 21 attract each other; during operation, when the support frame 9 moves to one end of the guide rail 8, the connection... Gear 17 at ring 16 meshes with gear 19 at base 18. Then, servo motor 3 drives gear 19 to rotate, which in turn drives gear 17 and connecting ring 16 to rotate together. The rotating connecting ring 16 will drive pressure rod 12, sleeve 13 and sponge 15 to rotate 180 degrees. This ensures that sponge 15 is always located downstream of the support frame 9 in the direction of movement, so that the oil mist sprayer 11 sprays oil mist first and then sponge 15 spreads it evenly. This allows the support frame 9 to lubricate the punch 6 and die 2 during the back-and-forth movement on the guide rail 8. At the same time, every time the connecting ring 16 rotates 180 degrees, the magnetic post 20 on the surface of the connecting ring 16 will attract the magnetic block 21, thereby fixing the position of the connecting ring 16 and reducing the shaking of pressure rod 12.

[0024] like Figure 1 and Figure 7As shown, a partition plate 22 is inserted into the top surface of the workbench 1; the punch 6 and the die 2 are both located inside the partition plate 22; a feed inlet 23 is provided on one side of the partition plate 22; a pair of symmetrically arranged suction ports 24 are provided on the side of the partition plate 22 away from the feed inlet 23; a suction assembly is fixedly connected to the suction port 24; the suction assembly draws air from inside the partition plate 22 through the suction port 24; during operation, after the oil mist spraying operation is completed, the partition plate 22 effectively prevents oil from escaping into the external environment, and at the same time, the suction assembly will also be activated to draw air from inside the partition plate 22, so that excess oil mist is drawn away from the suction port 24 by the suction assembly, so as to prevent oil mist from escaping from the feed inlet 23.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, insert plates 25 are slidably connected to both sides of the pressure plate 5, and the insert plates 25 are fixed to the pressure plate 5 by pins; slots 26 are provided on both sides of the enclosure plate 22 near the top, and the slots 26 are adapted to the insert plates 25; during operation, when the user needs to lift the enclosure plate 22 to inspect the punch 6 and the die 2, the user can slide the insert plates 25 on the pressure plate 5 so that the insert plates 25 are inserted into the slots 26 on the surface of the enclosure plate 22. Then, as the hydraulic cylinder 7 drives the pressure plate 5 to rise, it can also drive the enclosure plate 22 to rise, thus facilitating the user's maintenance operation.

[0026] like Figure 1 , Figure 8 and Figure 9As shown, the suction assembly includes an air guide pipe 27; the air guide pipe 27 is fixedly connected to the surface of the enclosure plate 22 and located at the corresponding position of the suction port 24; an exhaust pipe 28 is fixedly connected to the side of the air guide pipe 27 away from the suction port 24; the exhaust pipe 28 is perpendicular to the air guide pipe 27, and an exhaust fan is provided at the top of the air guide pipe 27; multiple evenly arranged exhaust ports 29 are opened on the surface of the exhaust pipe 28 near the bottom; a support plate 30 is provided at the bottom of the exhaust pipe 28, and the support plate 30 is fixedly connected to the surface of the exhaust pipe 28 by bolts; an oil collection tank 31 is provided on the top surface of the support plate 30, and the top of the oil collection tank 31 is adapted to the inner wall of the exhaust pipe 28; during operation, when the suction assembly performs suction, the exhaust... The fan blows air into the exhaust pipe 28. The air velocity at the exhaust pipe 28 is high. According to Bernoulli's principle, the higher the velocity, the lower the pressure. Therefore, the side of the air duct 27 near the exhaust pipe 28 is a low-pressure area. This causes the air duct 27 to draw air from inside the enclosure 22, thus also drawing away the oil mist. After the oil mist is finally drawn into the exhaust pipe 28, the fan at the top of the exhaust pipe 28 blows the oil into the oil collection tank 31 at the bottom, where it sticks. The air is then discharged from the exhaust port 29. Afterward, the user can remove the tray 30 and take the oil collection tank 31 out of the exhaust pipe 28, thus reusing the lubricating oil in the oil collection tank 31.

[0027] like Figures 8 to 9 As shown, a guide plate 32 is fixedly connected to the side wall of the exhaust pipe 28 at the corresponding position of the exhaust port 29, and the guide plate 32 is inclined; baffles 33 are fixedly connected to both sides of the guide plate 32; a connecting frame 34 is provided on the surface of the exhaust pipe 28 at the top of the guide plate 32, and the connecting frame 34 is connected to the surface of the exhaust pipe 28 by bolts; an oil separator 35 is embedded between the guide plate 32 and the baffles 33 on the surface of the connecting frame 34; during operation, when air is discharged from the exhaust port 29, some oil mist may still remain in the air. Due to the guidance of the guide plate 32 and the baffles 33, the air will be filtered by the oil separator 35 after being discharged from the exhaust port 29, so that the oil mist is filtered down and flows back to the interior of the exhaust pipe 28 along the guide plate 32, and finally collects in the oil collection tank 31, thereby further reducing the pollution to the external environment.

[0028] like Figures 9 to 10As shown, two pairs of symmetrically arranged fixing blocks 36 are fixedly connected to the top surface of the tray 30, and the oil collection tank 31 is located between the fixing blocks 36; a second spring 37 is embedded on the side of the pair of fixing blocks 36 that is close to each other; a clamping plate 38 is fixedly connected to the end of the second spring 37 away from the fixing blocks 36, and the top of the clamping plate 38 is inclined; during operation, when the oil collection tank 31 is placed on the tray 30, the bottom of the oil collection tank 31 will insert between the clamping plates 38 and compress the second spring 37 between the fixing blocks 36 and the clamping plates 38. Thus, through the elastic force of the second spring 37, the clamping plate 38 clamps the oil collection tank 31, thereby preventing the oil collection tank 31 from sliding freely on the surface of the tray 30, which would cause the lubricating oil in the oil collection tank 31 to spill out.

[0029] like Figure 1 and Figure 11 As shown, an electric push rod 39 is slidably connected to the top surface of the workbench 1 near the feed inlet 23, and the electric push rod 39 is driven by a servo motor. A rotating plate 40 is rotatably connected to the telescopic end of the electric push rod 39, and the rotating plate 40 is driven by a servo motor. Multiple evenly arranged vacuum suction cups 41 are embedded on the bottom surfaces of both ends of the rotating plate 40. A pair of conveyor belts 42 are provided on the side of the workbench 1 near the electric push rod 39. During operation, to facilitate loading and unloading, the electric push rod 39 drives the rotating plate 40 to move to the top surface of one of the conveyor belts 42. Then, the electric push rod 39 drives the rotating plate 40 to descend, thereby adsorbing the material on the conveyor belt 42. The rotating plate 40 then rotates 180 degrees, so that the end of the rotating plate 40 adsorbing the material faces the feed inlet 23. Afterward, the electric push rod 39 moves... The rotating plate 40 and the material are fed between the punch 6 and the die 2. Then, the electric push rod 39 drives the rotating plate 40 to move out of the enclosure 22. At the same time, the end of the rotating plate 40 away from the enclosure 22 picks up the material from the conveyor belt 42 again. After the material between the punch 6 and the die 2 is stamped, the electric push rod 39 drives the rotating plate 40 to extend into the enclosure 22 and picks up the stamped bracket. Then, the electric push rod 39 drives the rotating plate 40 to move to the outside of the enclosure 22. Then, the rotating plate 40 rotates 90 degrees and places the processed bracket on the surface of another conveyor belt 42. Then, the rotating plate 40 rotates another 90 degrees and faces the end of the rotating plate 40 with the material to be processed toward the feed port 23. This completes one loading and unloading process, thereby reducing the user's operation and improving production efficiency.

[0030] like Figure 1 , Figure 7 and Figure 12As shown, a cover plate 43 is rotatably connected to the top of the feed inlet 23 on the inner wall of the enclosure 22; rubber pads 44 are fixedly connected to both the side of the cover plate 43 near the enclosure 22 and the side of the enclosure 22 near the cover plate 43; multiple evenly arranged magnetic pieces 45 are embedded inside the rubber pads 44; during operation, when the rotating plate 40 moves towards the feed inlet 23, the rotating plate 40 will squeeze the cover plate 43, causing the cover plate 43 to flip, so that the rotating plate 40 can normally enter the enclosure 22. When the rotating plate 40 is pushed to the outside of the enclosure 22, the cover plate 43, under the action of gravity, will be fastened to the feed inlet 23. At the same time, the cover plate 43 and the rubber pad 44 at the feed inlet 23 will stick to each other, and the magnetic pieces 45 inside the rubber pad can attract the cover plate 43 to the feed inlet 23, thereby improving the sealing performance of the enclosure 22 and further reducing the oil mist from escaping to the external environment.

[0031] During operation, to reduce wear on the die from continuous stamping, this embodiment of the invention can be used. During normal stamping, the material to be stamped is placed at the die cavity 2. Then, the hydraulic cylinder 7 drives the pressure plate 5 to descend, which in turn moves the punch 6 towards the worktable 1, squeezing the material at the die cavity 2, thus completing the stamping operation. Afterwards, the hydraulic cylinder 7 drives the pressure plate 5 and the punch 6 to rise, and the ejector block 3 at the die cavity 2 ejects, thereby pushing the stamped car bracket out of the die cavity 2, thus completing the entire stamping operation. To reduce wear on the punch 6 and the die cavity 2 and extend their service life, after completion... After multiple stamping operations, the support frame 9 slides along the guide rail 8, thereby driving the movable seat 10 on it to pass completely over the surfaces of the punch 6 and the die 2. During this process, the movable seat 10 is driven by the servo motor 2 to slide on the surface of the support frame 9, thereby driving the oil mist sprayer 11 to sweep over the protrusion of the punch 6 and the top block 3 of the die 2. During this process, the oil mist sprayer 11 will spray lubricating oil mist, so that a layer of oil film adheres to the protrusion of the punch 6 and the top block 3 of the die 2, thereby reducing the friction in the subsequent stamping process, thus reducing the wear of the punch 6 and the die 2, and extending their service life.

[0032] During the process of the oil mist sprayer 11 spraying oil mist onto the surfaces of the die 2 and the punch 6, the movement of the support frame 9 and the movable seat 10 will also drive the pressure rod 12 and the sleeve 13 to move synchronously, thereby driving the sponge 15 to move synchronously, thus achieving the application of lubricating oil. This allows the lubricating oil to be applied more evenly to the punch 6 and the die 2. The spring 14 between the pressure rod 12 and the sleeve 13 can ensure the pressure of the sponge 15 on the punch 6 and the die 2, further improving the application effect of the lubricating oil.

[0033] When the support frame 9 moves to one end of the guide rail 8, the gear 17 at the connecting ring 16 will mesh with the gear 19 at the base 18. Then, the servo motor drives the gear 19 to rotate, which in turn drives the gear 17 and the connecting ring 16 to rotate together. The rotating connecting ring 16 will then drive the pressure rod 12, the sleeve 13 and the sponge 15 to rotate 180 degrees. This ensures that the sponge 15 is always located downstream of the support frame 9 in the direction of movement, thus ensuring that the oil mist sprayer 11 sprays the oil mist first, and then the sponge 15 spreads it evenly. This allows the support frame 9 to lubricate the punch 6 and the die 2 during its back-and-forth movement on the surface of the guide rail 8. At the same time, every time the connecting ring 16 rotates 180 degrees, the magnetic column 20 on the surface of the connecting ring 16 will attract the magnetic block 21, thus fixing the position of the connecting ring 16 and reducing the shaking of the pressure rod 12.

[0034] After the oil mist spraying operation is completed, the enclosure 22 effectively prevents the oil from escaping into the external environment. At the same time, the suction component will also be activated to suction the inside of the enclosure 22, so that the excess oil mist is drawn away from the suction port 24 by the suction component, so as to prevent the oil mist from escaping from the feed port 23.

[0035] When the user needs to lift the enclosure 22 to inspect the punch 6 and die 2, the user can slide the insert plate 25 at the pressure plate 5 so that the insert plate 25 is inserted into the slot 26 on the surface of the enclosure 22. Then, as the hydraulic cylinder 7 drives the pressure plate 5 to rise, it can also drive the enclosure 22 to rise, thus facilitating the user's maintenance operation.

[0036] When the suction assembly performs suction, the exhaust fan blows air into the exhaust pipe 28. According to Bernoulli's principle, the higher the air velocity at the exhaust pipe 28, the lower the pressure. Therefore, the side of the air guide pipe 27 near the exhaust pipe 28 is a low-pressure area, which causes the air guide pipe 27 to draw air from inside the enclosure 22, thereby also drawing away the oil mist. After the oil mist is finally drawn into the exhaust pipe 28, the fan at the top of the exhaust pipe 28 blows the oil sludge drawn into the exhaust pipe 28 into the oil collection tank 31 at the bottom, where it sticks. The air is then discharged from the exhaust port 29. Afterward, the user can remove the tray 30 and take the oil collection tank 31 out of the exhaust pipe 28, thus reusing the lubricating oil in the oil collection tank 31.

[0037] When air is discharged from exhaust port 29, some oil mist may still remain in the air. However, due to the guidance of guide plate 32 and baffle 33, the air will pass through the oil separator 35 after being discharged from exhaust port 29, so that the oil mist is filtered down and flows back into the exhaust pipe 2 along guide plate 32, and finally collects in oil collection tank 31, thereby further reducing pollution to the external environment.

[0038] When the oil collection tank 31 is placed on the tray 30, the bottom of the oil collection tank 31 will be inserted between the clamping plates 38 and compress the spring 37 between the fixing block 36 and the clamping plate 38. Thus, through the elastic force of the spring 37, the clamping plate 38 clamps the oil collection tank 31, thereby preventing the oil collection tank 31 from sliding freely on the surface of the tray 30, which would cause the lubricating oil in the oil collection tank 31 to spill out.

[0039] To facilitate loading and unloading, the electric actuator 39 moves the rotating plate 40 to the top surface of one of the conveyor belts 42. Then, the electric actuator 39 lowers the rotating plate 40, thereby adsorbing the material on the conveyor belt 42. The rotating plate 40 then rotates 180 degrees, so that the end of the rotating plate 40 with the material adsorbed faces the feed inlet 23. The electric actuator 39 then moves to feed the rotating plate 40 and the material between the punch 6 and the die 2. The electric actuator 39 then moves the rotating plate 40 out of the enclosure 22, while the end of the rotating plate 40 away from the enclosure 22 adsorbs another conveyor belt 42. After the material between the punch 6 and the die 2 is stamped, the electric push rod 39 drives the rotating plate 40 to extend into the enclosure 22 and pick up the stamped bracket. Then, the electric push rod 39 drives the rotating plate 40 to move to the outside of the enclosure 22. Subsequently, the rotating plate 40 rotates 90 degrees and places the processed bracket on the surface of another conveyor belt 42. Then, the rotating plate 40 rotates another 90 degrees, so that the end of the rotating plate 40 that picks up the material to be processed faces the feed port 23, thus completing a loading and unloading process, thereby reducing the user's operation and improving production efficiency.

[0040] When the rotating plate 40 moves toward the feed inlet 23, it will press the cover plate 43, causing the cover plate 43 to flip so that the rotating plate 40 can enter the enclosure 22 normally. When the rotating plate 40 is pushed to the outside of the enclosure 22, the cover plate 43 will be pressed against the feed inlet 23 under the action of gravity. At the same time, the rubber pad 44 at the feed inlet 23 and the cover plate 43 will stick together. The magnetic piece 45 inside the rubber can attract the cover plate 43 to the feed inlet 23, thereby improving the sealing of the enclosure 22 and further reducing the oil mist from escaping into the external environment.
