DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-7A fuel tank cover outer plate stamping die with a metal chip cleaning structure comprises a lower die base 1, a guide rod 2 and an upper die base 3. A lower die 13 is detachably mounted on the upper end of the lower die base 1, an upper die 32 is detachably mounted on the lower end of the upper die base 3, the upper die base 3 moves up and down along the guide rod 2, a driving frame 4 is fixedly connected to the left and right sides of the lower die base 1, a driving groove 42 is provided on the inner side of the upper end of the driving frame 4, a threaded rod 421 and a movable moving block 422 are provided inside the driving groove 42, a mounting plate 43 is fixedly connected to the side surface of the moving block 422, a brushing mechanism 5 and a blowing mechanism 6 are fixedly connected to the side surface of the mounting plate 43, A cleaning roller 52 is sleeved in the middle of the brush cleaning mechanism 5, and a plurality of nylon bristles 521 are fixedly arranged on the surface of the cleaning roller 52. The middle of the blowing mechanism 6 is open at the top and bottom, and a blowing fan 62 is arranged inside. A lubricating mechanism 7 is fixedly mounted on the upper surface of one side of the lower die base 1, and an oil tank 71 is fixedly installed on the upper end of the lubricating mechanism 7. The oil tank 71 is filled with stamping oil. When in use, when the brush cleaning mechanism 5 moves toward the lubricating mechanism 7 and completes the task of cleaning metal debris during movement, the cleaning roller 52 moves to the rightmost end. At this time, the nylon bristles 521 are in contact with the inside of the oil tank 71, and the oil tank 71 is slightly lower than the cleaning roller 52. Figure 5 As shown, the nylon bristles 521 will rotate to absorb the stamping oil, and then the brush cleaning mechanism 5 will move back to its original position. During the return process, the nylon bristles 521 will rotate to apply the stamping oil to the mold cavities of the lower mold 13 and the upper mold 32, so that a lubricating film is formed inside the mold cavity. This lubricating film can reduce the friction coefficient and reduce wear, thereby reducing the generation of metal chips, thereby fundamentally reducing the generation of scratches and improving the overall practicality.

[0021] Furthermore, a connecting plate 11 is fixedly connected to the upper surface of the lower die base 1, a lower die pad 12 is fixedly connected to the upper surface of the connecting plate 11, the lower die 13 is located at the upper end of the lower die pad 12, and first quick-release plates 131 are fixedly connected on both sides of the lower die 13. A first bolt 132 is threadedly connected to the surface of the first quick-release plate 131, and the first bolt 132 threadably penetrates the first quick-release plate 131 and threadedly penetrates into the interior of the lower die pad 12. During use, when the lower die 13 is severely worn and needs to be replaced, the staff can screw the first bolt 132 to separate the first quick-release plate 131 from the lower die pad 12, thereby completing the quick release of the lower die 13 and timely replacing the worn lower die 13.

[0022] Furthermore, a shaft sleeve 21 is provided at the connection between the upper die base 3 and the guide rod 2, and an upper die pad 31 is fixedly connected to the lower surface of the upper die base 3, and the upper die 32 is located at the lower end of the upper die pad 31. Second quick-release plates 321 are fixedly connected to both sides of the upper die 32, and second bolts 322 are threadedly connected to the surface of the second quick-release plates 321. The second bolts 322 threadably penetrate the second quick-release plates 321 and threadedly penetrate into the interior of the upper die pad 31. A driving handle 33 is fixedly connected to the upper surface of the upper die base 3. During use, when the upper die 32 is severely worn and needs to be replaced, the staff can screw the second bolt 322 to disengage the second quick-release plate 321 from the upper die pad 31, thereby completing the quick release of the upper die 32 and timely replacing the worn upper die 32. By connecting the hydraulic structure through the driving handle 33, the upper die 32 can move downward and cooperate with the lower die 13 to complete the stamping process.

[0023] Furthermore, a first motor 41 is installed on the front surface of the driving frame 4. The first motor 41 passes through the interior of the driving groove 42 and is transmission-connected to the threaded rod 421. The outer surface of the threaded rod 421 is threadedly connected to the moving block 422. When in use, by driving the first motor 41, the first motor 41 drives the first motor 41 to rotate, and the moving block 422 can drive the mounting plate 43 and the brushing mechanism 5 and the blowing mechanism 6 to move forward and backward. When the brushing mechanism 5 and the blowing mechanism 6 move to the front and rear ends, they will not cause motion interference to the upper mold 32.

[0024] Furthermore, one end of the brushing mechanism 5 is connected to a second motor 51, and the second motor 51 is fixedly connected to one side of the mounting plate 43. The output end of the second motor 51 is transmission-connected to the brushing mechanism 5. The length of the cleaning roller 52 is consistent with the width of the lower mold 13 and the upper mold 32. The nylon bristles 521 are in conflict with the mold cavities of the lower mold 13 and the upper mold 32. When in use, the second motor 51 is started to drive the brushing mechanism 5 to rotate, which in turn drives the cleaning roller 52 and the nylon bristles 521 to rotate. The nylon bristles 521 rotate and cooperate with the forward movement, so that the inside of the mold cavity of the lower mold 13 and the upper mold 32 can be brushed, and the residual metal debris can be effectively removed to avoid metal debris causing scratches on the surface of the workpiece during the stamping process, thereby improving the stamping quality and the appearance of the workpiece surface.

[0025] Furthermore, a third motor 61 is installed inside one end of the blowing mechanism 6, and the output end of the third motor 61 is transmission-connected to the blowing fan 62, and a filter 63 is installed at the upper and lower openings in the middle of the blowing mechanism 6. When in use, by starting the third motor 61, the third motor 61 drives the blowing fan 62 to rotate, and the blowing fan 62 generates a blowing force, and the blowing force blows air into the mold cavities of the lower mold 13 and the upper mold 32 through the upper and lower openings inside the blowing mechanism 6, which can further cooperate with brushing to blow away the metal debris remaining in the mold cavity, thereby further improving the cleaning effect of the residual metal debris and increasing the overall practicality.

[0026] Base oil and additives: The base oil part includes synthetic ester oil 30% - 40%, poly alpha olefin PAO, 30% - 40%; The additive part includes extrusion anti-wear agent 10% - 15%, oiliness agent 5% - 10%, antioxidant 3% - 5%, rust inhibitor 2% - 3%, and anti-foaming agent 0.5% - 1%.

[0027] Synthetic ester oil has good lubrication performance, thermal stability and oxidation stability. For example, trimethylolpropane oleate can form a stable oil film on the surface of the mold and the material, effectively reducing the friction coefficient. The ester bond in its molecular structure can provide good lubricity and is not easy to decompose under the high pressure and high temperature environment during the stamping process. During the stamping process, synthetic ester oil can not only form a stable oil film and reduce the friction coefficient, but also ensure the integrity of the oil film during the frequent contact and separation between the mold and the material. PAO is a synthetic base oil with excellent low-temperature fluidity and high-temperature stability. In low-temperature environments, it can quickly reach the contact surface between the mold and the material, and will not easily evaporate or deteriorate during high-temperature stamping. For example, 4-cSt PAO can maintain good lubrication performance over a wide temperature range, reducing the friction between the mold and the outer plate material of the fuel tank cover. During continuous stamping, the mold temperature gradually increases, and PAO can continue to maintain lubrication performance, ensuring smooth stamping between the mold and the outer plate material of the fuel tank cover, reducing material surface scratches and mold damage caused by poor lubrication; Sulfurized olefins: This extreme pressure anti-wear agent can react chemically with the metal surface in the high-pressure area during the stamping process to form a sulfide protective film. For example, at the contact point between the mold and the fuel tank cover outer plate material, when the pressure increases, the sulfur element in the sulfurized olefin reacts with the metal surface to prevent direct contact between the metals, greatly reducing wear and reducing the generation of metal chips. When stamping the fuel tank cover outer plate with a complex shape, the pressure in different parts is different. Sulfurized olefins can effectively reduce wear in each pressure area and ensure stamping accuracy. Oleic acid amide: It can be adsorbed on the surface of the mold and the material to further reduce the friction coefficient. The polar groups in the oleic acid amide molecules can produce adsorption with the metal surface, while the non-polar long-chain hydrocarbon groups face outward to form a low-friction lubricating layer, making the stamping process smoother. During the stamping process, the low-friction lubricating layer formed by the adsorption of oleic acid amide on the surface of the mold and the material not only reduces the friction coefficient, but also improves the speed and accuracy of stamping; Di-tert-butyl paracresol BHT: During the use of stamping oil, due to the influence of high temperature, air and other factors, oxidation reaction is prone to occur. BHT can inhibit the oxidation process of stamping oil and extend the service life of stamping oil. It can capture free radicals in the oil, prevent the chain oxidation reaction of oil molecules, and maintain the performance of stamping oil. In long-term stamping production, BHT can ensure that the stamping oil always maintains good performance, reduce the frequency of stamping oil replacement due to oxidation, and reduce production costs; Barium petroleum sulfonate: During the stamping process, if there is water vapor on the surface of the mold or the outer panel of the fuel tank cover or it may be exposed to moisture during storage, it is easy to rust. Barium petroleum sulfonate can form an anti-rust film on the metal surface to prevent rust. For example, on the mold surface, barium petroleum sulfonate can prevent rust caused by moisture, thereby maintaining the accuracy of the mold and reducing the risk of increased surface roughness and metal chips caused by rust. In addition to preventing rust, the anti-rust film formed by barium petroleum sulfonate can also play a certain isolation role. It can isolate corrosive substances that may be mixed in the stamping process, such as acidic gases in the air or some chemical residues in the processing process; Methyl silicone oil: Stamping oil is prone to generate foam during the circulation process. The foam will affect the lubrication effect and the normal supply of stamping oil. Methyl silicone oil can reduce the surface tension of stamping oil, make the foam burst quickly, and ensure that the stamping oil forms a stable lubricating film on the surface of the mold and material.

[0028] In summary, the present invention proposes a fuel tank cover outer panel stamping die with a metal chip cleaning structure. When in use, the brushing mechanism 5 drives the cleaning roller 52 to rotate through the second motor 51, and the nylon bristles 521 on the cleaning roller 52 contact the surface of the mold cavity, and remove the residual metal debris in the cavity by moving back and forth. At the same time, the blowing mechanism 6 follows closely and drives the blowing fan 62 to rotate through the third motor 61 to generate a blowing force to further blow away the residual metal debris. After cleaning, the brushing mechanism 5 moves to the lubrication mechanism 7, and the nylon bristles 521 on the cleaning roller 52 are attached to the stamping oil in the fuel tank 71. When the brushing mechanism 5 moves back to its original position, the nylon bristles 521 brush the stamping oil away. Coated in the mold cavity to form a lubricating film, reduce the friction coefficient, reduce wear, synthetic ester oil and PAO provide good lubrication performance and thermal stability, sulfurized olefins form a sulfide protective film in the high-pressure area to prevent direct metal contact and reduce wear, oleic acid amide further reduces the friction coefficient, BHT inhibits the oxidation process of stamping oil and extends the service life, petroleum barium sulfonate prevents mold rust and maintains mold accuracy, methyl silicone oil reduces the surface tension of stamping oil, prevents foaming, and ensures lubrication effect. Through the above working principle, the stamping mold can efficiently clean metal chips, lubricate the mold in time, quickly replace worn molds, and use high-performance stamping oil, thereby improving stamping quality and efficiency.
