Technical Field

[0001] The invention relates to the technical field of metal stamping processing, and in particular to a high-quality metal stamping forming forging device and method. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

[0004] However, in the above patent, when a groove is punched out of the metal plate, the groove part will first be deformed, which will cause the two sides of the metal plate to gradually warp up. Due to the lack of a horizontal pulling force on the warped area, it is easy for the warped area to gradually bend when it comes into contact with and squeezed by the upper stamping plate. It is very likely that wrinkles will appear when the bent part is stamped, thereby failing to ensure high-quality stamping of the metal plate. Summary of the invention

[0014] Preferably, an extrusion plate is fixedly mounted on the three upper ends of the connecting rod, an elastic member is provided on the lower side of the extrusion plate, and the upper end of the elastic member is fixedly connected to the bracket.

[0015] A method for high-quality metal stamping forming forging device, the specific steps are as follows: Step 1: The fixed plate is lowered to squeeze the airbag, and the gas is ejected through the connecting pipe and the nozzle plate to evenly remove the debris and impurities adhering to the L-shaped plate and the fixed plate; Step 2: The stamping plate is lowered to drive the support frame, guide rod, spring 1, magnetic frame and pressing roller to descend synchronously to press the metal sheet; Step 3: Fix the two ends of the metal sheet on the L-shaped plate through the fixing plate and the L-shaped plate, and provide a pulling force to the two ends of the metal sheet to ensure that the two ends of the metal sheet will not bend or bulge; Step 4: Use spring 4 to push the shaping plate, connecting rod 3 and extrusion plate to quickly descend and reset, so that the shaping plate can be used to tamp the stamping plate after mold closing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the hydraulic cylinder is started to drive the stamping plate to descend, and the stamping plate and the groove plate cooperate to stamp the metal sheet, which is convenient for processing the metal sheet into a groove shape. When the stamping plate descends, it will also drive the support frame to descend synchronously, and the support frame drives the guide rod, spring 1, magnetic frame and pressing roller to descend synchronously. The lower end of the pressing roller is lower than the lower end of the stamping plate, so the pressing roller will first contact the metal sheet on the groove plate and press the metal sheet. As the stamping plate continues to descend, the spring 1 is squeezed, and the pressing roller is convenient for pressing both sides of the metal sheet to prevent the two sides of the metal sheet from warping up when the groove is stamped on the metal sheet, and being restricted by the descent of the stamping plate, resulting in bending of the two sides of the metal sheet, thereby avoiding wrinkles on both sides of the metal sheet during subsequent stamping, thereby improving the high-quality stamping of the metal sheet.

[0017] 2. In the present invention, when the magnetic rack descends to the side where the magnetic racks on both sides are close to each other, a magnetic repulsive force is generated on the magnetic racks, thereby pushing the magnetic racks on both sides to slide in the direction away from each other, and the magnetic rack drives the gear to rotate, and the gear drives the screw to rotate on the L-shaped plate, and the screw drives the fixed plates on both sides to slide and descend on the L-shaped plate, which is convenient for fixing the two ends of the metal sheet on the L-shaped plate. The iron block is convenient for attracting the magnetic rack, ensuring that the magnetic rack will not slide naturally, and ensuring the stable clamping force of the fixed plate. When a groove is stamped in the middle of the metal sheet, the two sides of the metal sheet will move toward the middle, and at this time, the L-shaped plates, connecting rod 1 and connecting plate on both sides will move close to each other, compressing the spring 2, so as to provide a pulling force to the two ends of the metal sheet, ensuring that the two ends of the metal sheet will not bend or bulge, thereby again having a good effect on improving the high-quality stamping of the metal sheet.

[0018] 3. In the present invention, when the connecting plates on both sides move towards each other, the limit block will be squeezed, so that the limit block drives the second connecting rod to slide upward on the horizontal plate until the connecting plate passes over the lower end of the limit block, and the connecting plate and the limit block are separated from each other. When the limit blocks reach the side close to each other, the limit block and the second connecting rod slide down under the action of gravity, and the connecting plate and the limit block fit each other to limit the end of the connecting plate that is away from each other. When the metal sheet is stamped, the staff pushes the magnetic racks on both sides to reset, and then drives the fixed plate to move up and reset through the gear and the screw, loosens the two ends of the metal sheet, and then pulls The connecting rod 2 and the limit blocks on both sides are moved up to separate the limit blocks from the connecting plate. Under the action of the second spring, the connecting rod 1, the connecting plate and the L-shaped plate are pushed to reset, so that the L-shaped plate is separated from the two ends of the metal sheet. Since the L-shaped plates on both sides are not separated synchronously, the limit blocks on both sides are set to facilitate the separation of the L-shaped plate and the fixed plate on one side from one end of the metal sheet, and effectively limit the undisassembled L-shaped plate and the fixed plate on the other side, to prevent the spring from continuing to provide a strong pulling force on one side of the metal sheet under the action of the second spring, resulting in deformation and scrapping of the metal sheet, thereby improving the stamping quality of the metal sheet.

[0019] 4. In the present invention, when the fixed plate slides and descends on the L-shaped plate, the airbag is also squeezed, and the gas is ejected through the connecting pipe and the nozzle plate. When the fixed plate descends, the nozzle plate is pulled to slide and rise on the L-shaped plate by the traction of the wire rope, and the compression spring three is conducive to making the gas ejected from the nozzle plate to evenly clean and spray off the debris and impurities adhered to the L-shaped plate and the fixed plate, thereby avoiding the debris and impurities adhered to the L-shaped plate and the fixed plate, resulting in unstable clamping of the metal sheet.

[0020] 5. In the present invention, when the stamping plate and the support frame descend, the shaping plate, the connecting rod three, the spring four and the extrusion plate will also be driven to descend synchronously. The extrusion plate will gradually contact with the elastic member and be subject to the resistance of the elastic member, driving the extrusion plate, the connecting rod three and the shaping plate to be suspended in the air and slide on the support frame, compressing the spring four. When the stamping plate and the groove plate are molded together, the pressure of the spring four reaches the maximum. At this time, the elastic member will gradually deform until it is separated from the extrusion plate. At this time, under the action of the spring four, the shaping plate, the connecting rod three and the extrusion plate are pushed to quickly descend and reset. The shaping plate is convenient for tamping the stamping plate after the mold is closed, which has a good auxiliary effect on the shaping of the metal sheet, thereby further improving the stamping quality of the metal sheet.

A gear 14 is fixedly installed on the upper end of the screw 13, and a magnetic rack 15 is meshed at the front end of the gear 14. The lower end of the magnetic rack 15 is slidably installed on the L-shaped plate 11, and iron blocks 16 are fixedly installed on the corresponding magnetic racks 15 on the left and right ends of the inner side of the bracket 2. The ends of the L-shaped plates 11 that are away from each other are fixedly installed with connecting rods 17, and the ends of the connecting rods 17 that are away from each other are The connecting rod 1 17 is installed on the bracket 2 through sliding, and the ends away from each other are fixedly installed with a connecting plate 18, and the outer side of the connecting rod 1 17 is sleeved with a spring 2 19, and the two ends of the spring 2 19 are respectively fixedly connected to the bracket 2 and the connecting plate 18, and the upper side of the connecting plate 18 is provided with a limit block 20, and the upper end of the limit block 20 is fixedly installed with a connecting rod 21, and the upper end of the connecting rod 21 is installed with a horizontal plate 22 through sliding, and the horizontal plate 22 is respectively fixedly installed on the left and right ends of the bracket 2; During operation, the hot-melt liquid metal is cooled and formed from the mold to obtain a metal sheet, and then the metal sheet is placed on the groove plate 3, and the hydraulic cylinder 5 is started to drive the stamping plate 4 to descend. The stamping plate 4 cooperates with the groove plate 3 to stamp the metal sheet, which is convenient for processing the metal sheet into a groove shape. When the stamping plate 4 descends, it will also drive the support frame 9 to descend synchronously, and the support frame 9 drives the guide rod 8, the spring 10, the magnetic frame 7 and the pressing roller 6 to descend synchronously. The lower end of the pressing roller 6 is lower than the lower end of the stamping plate 4, so the pressing roller 6 will first contact the metal sheet on the groove plate 3 and press the metal sheet. As the stamping plate 4 continues to descend, the spring 10 is squeezed, and the pressing roller 6 is convenient for pressing both sides of the metal sheet to prevent the metal sheet from being concavely stamped. When the groove is formed, the two sides of the metal sheet will be lifted up and restricted by the descent of the stamping plate 4, resulting in bending of the two sides of the metal sheet, thereby avoiding wrinkles on the two sides of the metal sheet during subsequent stamping, thereby improving the high-quality stamping of the metal sheet. When the magnetic frame 7 descends to the side where the magnetic racks 15 on both sides are close to each other, a magnetic repulsive force is generated on the magnetic racks 15, thereby pushing the magnetic racks 15 on both sides to slide away from each other, and the magnetic racks 15 drive the gears 14 to rotate, and the gears 14 drive the screws 13 to rotate on the L-shaped plates 11, and the screws 13 drive the fixing plates 12 on both sides to slide down on the L-shaped plates 11, so as to fix the two ends of the metal sheet on the L-shaped plates 11, and the iron blocks 16 are arranged to attract the magnetic racks 15, ensuring The magnetic rack 15 will not slide naturally, ensuring the stable clamping force of the fixed plate 12. When the groove is stamped in the middle of the metal sheet, the two sides of the metal sheet will move toward the middle. At this time, the L-shaped plates 11, connecting rod 17 and connecting plate 18 on both sides will move closer to each other, and the compression spring 2 19 is convenient for providing a pulling force to the two ends of the metal sheet, ensuring that the two ends of the metal sheet will not bend and bulge, thereby once again having a good effect on improving the high-quality stamping of the metal sheet. When the connecting plates 18 on both sides move closer to each other, the limit block 20 will be squeezed, so that the limit block 20 drives the connecting rod 21 to slide upward on the cross plate 22 until the connecting plate 18 passes the lower end of the limit block 20, and the connecting plate 18 and the limit block 20 are separated from each other. , when reaching the side where the limit blocks 20 are close to each other, the limit blocks 20 and the second connecting rod 21 slide down under the action of gravity, and the connecting plate 18 fits with the limit blocks 20 to limit the end of the connecting plate 18 that is away from each other. When the metal sheet is stamped, the staff pushes the magnetic racks 15 on both sides to reset, and then drives the fixed plate 12 to move up and reset through the gear 14 and the screw 13, loosens the two ends of the metal sheet, and then pulls the two connecting rods 21 and the limit blocks 20 on both sides to rise in turn, so that the limit blocks 20 are separated from the connecting plate 18. Under the action of the second spring 19, the connecting rod 17, the connecting plate 18 and the L-shaped plate 11 are pushed to reset, so that the L-shaped plate 11 is separated from the two ends of the metal sheet. Since the L-shaped plates 11 on both sides are not separated synchronously,Therefore, by setting the limit blocks 20 on both sides, when the L-shaped plate 11 and the fixing plate 12 on one side are separated from one end of the metal sheet, the L-shaped plate 11 and the fixing plate 12 on the other side that have not been removed are effectively limited, so as to prevent the spring 2 19 from continuing to provide a strong pulling force on one side of the metal sheet, causing the metal sheet to be deformed and scrapped, thereby improving the stamping quality of the metal sheet.

[0025] As an embodiment of the present invention, an auxiliary mechanism is also provided for assisting in cleaning the residual debris on the L-shaped plate 11 and assisting in tamping the stamping plate 4 after stamping. The auxiliary mechanism includes a nozzle plate 23 slidably mounted on the front end of the L-shaped plate 11, and a shaping plate 29 that is fitted and abutted on the upper end of the stamping plate 4 and is symmetrically arranged on the left and right. A connecting rod 30 is fixedly mounted on the upper end of the shaping plate 29, and a spring 4 31 is sleeved on the outer side of the connecting rod 30. A connecting pipe 24 is provided at the rear end of the nozzle plate 23, and an air bag 25 is provided at the rear end of the connecting pipe 24. The upper and lower ends of the air bag 25 are respectively connected to The fixing plate 12 and the L-shaped plate 11 are fixedly connected, and the nozzle plate 23 is connected to the inside of the airbag 25 through the connecting pipe 24. A spring 3 26 is fixedly installed on the upper end of the nozzle plate 23, and the upper end of the spring 3 26 is fixedly connected to the L-shaped plate 11. A steel wire rope 27 is fixedly installed on the upper end of the nozzle plate 23, and the other end of the steel wire rope 27 is fixedly connected to the fixing plate 12, and a pulley 28 is fixedly installed on the L-shaped plate 11 corresponding to the steel wire rope 27. The upper ends of the connecting rods 30 are fixedly installed with extrusion plates 32, and elastic members 33 are provided on the lower side of the extrusion plates 32. The upper ends of the elastic members 33 are fixedly connected to the bracket 2. During operation, when the fixed plate 12 slides and descends on the L-shaped plate 11, the airbag 25 is also squeezed, and the gas is ejected through the connecting pipe 24 and the nozzle plate 23. When the fixed plate 12 descends, the nozzle plate 23 is pulled and slid upward on the L-shaped plate 11 by the wire rope 27, and the compression spring three 26 is conducive to the gas ejected from the nozzle plate 23 to evenly remove the debris and impurities adhered to the L-shaped plate 11 and the fixed plate 12, thereby avoiding the situation where the debris and impurities adhered to the L-shaped plate 11 and the fixed plate 12 cause the metal sheet to be clamped unstably. When the stamping plate 4 and the support frame 9 descend, the shaping plate 29, the connecting rod three 30, the spring four 31 and the squeezing frame 9 are also driven. The plates 32 descend synchronously, and the extrusion plate 32 will gradually contact the elastic member 33 and be resisted by the elastic member 33, driving the extrusion plate 32, the connecting rod three 30 and the shaping plate 29 to be suspended in the air and slide on the support frame 9, compressing the spring four 31. When the stamping plate 4 and the groove plate 3 are molded, the pressure of the spring four 31 reaches the maximum. At this time, the elastic member 33 will gradually deform until it is separated from the extrusion plate 32. At this time, under the action of the spring four 31, the shaping plate 29, the connecting rod three 30 and the extrusion plate 32 are pushed to quickly descend and reset. The shaping plate 29 is convenient for tamping the stamping plate 4 after the mold is closed, which has a good auxiliary effect on the shaping of the metal sheet, thereby further improving the stamping quality of the metal sheet.

[0026] A method for high-quality metal stamping forming forging device, the specific steps are as follows: Step 1: The fixed plate 12 is lowered to squeeze the airbag 25, and the gas is ejected through the connecting pipe 24 and the nozzle plate 23 to evenly remove the debris and impurities adhering to the L-shaped plate 11 and the fixed plate 12; Step 2: The stamping plate 4 is lowered to drive the support frame 9, the guide rod 8, the spring 10, the magnetic frame 7 and the pressing roller 6 to descend synchronously to press the metal sheet; Step 3: fix the two ends of the metal sheet to the L-shaped plate 11 through the fixing plate 12 and the L-shaped plate 11, and provide a pulling force to the two ends of the metal sheet to ensure that the two ends of the metal sheet will not bend or bulge; Step 4: Use spring 4 31 to push the shaping plate 29, connecting rod 30 and extrusion plate 32 to quickly descend and reset, so that the shaping plate 29 can tamp the stamping plate 4 after the mold is closed.

[0027] Working principle: When the present invention is used, the hot-melt liquid metal is cooled and formed from the mold to obtain a metal sheet, and then the metal sheet is placed on the groove plate 3, and the hydraulic cylinder 5 is started to drive the stamping plate 4 to descend. The stamping plate 4 cooperates with the groove plate 3 to stamp the metal sheet, which is convenient for processing the metal sheet into a groove shape. When the stamping plate 4 descends, it will also drive the support frame 9 to descend synchronously. The support frame 9 drives the guide rod 8, the spring 10, the magnetic frame 7 and the pressing roller 6 to descend synchronously. The lower end of the pressing roller 6 is lower than the lower end of the stamping plate 4, so the pressing roller 6 will first contact the metal sheet on the groove plate 3 and press the metal sheet. As the stamping plate 4 continues to descend, the spring 10 is squeezed, and the pressing roller 6 is convenient for pressing both sides of the metal sheet to prevent the metal sheet from being damaged. When punching the groove, the two sides of the metal sheet will be lifted up and restricted by the descent of the punching plate 4, resulting in bending of the two sides of the metal sheet, thereby avoiding wrinkles on the two sides of the metal sheet during subsequent punching, thereby improving the high-quality punching of the metal sheet. When the magnetic frame 7 descends to the side where the magnetic racks 15 on both sides are close to each other, a magnetic repulsive force is generated on the magnetic racks 15, thereby pushing the magnetic racks 15 on both sides to slide away from each other. The magnetic racks 15 drive the gears 14 to rotate, and the gears 14 drive the screws 13 to rotate on the L-shaped plates 11. The screws 13 drive the fixing plates 12 on both sides to slide down on the L-shaped plates 11, so as to fix the two ends of the metal sheet on the L-shaped plates 11. The iron blocks 16 are arranged to attract the magnetic racks 15 to ensure that the magnetic racks 15 are firmly fixed. The magnetic rack 15 is ensured not to slide naturally, and the stable clamping force of the fixed plate 12 is ensured. When the groove is punched in the middle of the metal sheet, the two sides of the metal sheet will move toward the middle. At this time, the L-shaped plates 11, the connecting rod 17 and the connecting plate 18 on both sides will move closer to each other, and the compression spring 2 19 is convenient for providing a pulling force to the two ends of the metal sheet, ensuring that the two ends of the metal sheet will not bend and bulge, thereby once again having a good effect on improving the high-quality stamping of the metal sheet. When the connecting plates 18 on both sides move closer to each other, the limit block 20 will be squeezed, so that the limit block 20 drives the connecting rod 21 to slide upward on the cross plate 22 until the connecting plate 18 passes over the lower end of the limit block 20, and the connecting plate 18 and the limit block 20 are separated from each other. When the limit blocks 20 are close to each other, the limit blocks 20 and the second connecting rod 21 slide down under the action of gravity, and the connecting plate 18 fits with the limit blocks 20 to limit the end of the connecting plate 18 that is away from each other. When the metal sheet is stamped, the staff pushes the magnetic racks 15 on both sides to reset, and then drives the fixed plate 12 to move up and reset through the gear 14 and the screw 13, and loosens the two ends of the metal sheet, and then pulls the second connecting rod 21 and the limit blocks 20 on both sides to rise in turn, so that the limit blocks 20 are separated from the connecting plate 18. Under the action of the second spring 19, the connecting rod 17, the connecting plate 18 and the L-shaped plate 11 are pushed to reset, so that the L-shaped plate 11 is separated from the two ends of the metal sheet. Since the L-shaped plates 11 on both sides are not separated synchronously,Therefore, by setting the limit blocks 20 on both sides, it is convenient to separate the L-shaped plate 11 and the fixed plate 12 on one side from one end of the metal sheet, and effectively limit the undisassembled L-shaped plate 11 and the fixed plate 12 on the other side, to prevent the spring 2 19 from continuing to provide a strong pulling force on one side of the metal sheet, resulting in deformation and scrapping of the metal sheet, thereby improving the stamping quality of the metal sheet. When the fixed plate 12 slides and descends on the L-shaped plate 11, it will also squeeze the air bag 25, and the gas will be ejected through the connecting pipe 24 and the nozzle plate 23. When the fixed plate 12 descends, the nozzle plate 23 will be pulled and slid upward on the L-shaped plate 11 by the wire rope 27, and the compression spring 3 26 will help the gas ejected from the nozzle plate 23 to evenly remove the debris and impurities adhered to the L-shaped plate 11 and the fixed plate 12, thereby avoiding the L-shaped plate 11 and the fixed plate 12 from being sprayed off. The debris and impurities adhering to the fixed plate 12 cause the metal sheet to be clamped unstably. When the stamping plate 4 and the support frame 9 are lowered, the shaping plate 29, the connecting rod 30, the spring 4 31 and the extrusion plate 32 are also driven to fall synchronously. The extrusion plate 32 will gradually contact the elastic member 33 and be resisted by the elastic member 33, driving the extrusion plate 32, the connecting rod 30 and the shaping plate 29 to be suspended in the air and slide on the support frame 9, compressing the spring 4 31. When the stamping plate 4 and the groove plate 3 are molded, the pressure of the spring 4 31 reaches the maximum. At this time, the elastic member 33 will gradually deform until it is separated from the extrusion plate 32. At this time, under the action of the spring 4 31, the shaping plate 29, the connecting rod 30 and the extrusion plate 32 are pushed to quickly fall and reset. The shaping plate 29 is convenient for tamping the stamping plate 4 after the mold is closed, which has a good auxiliary effect on the shaping of the metal sheet, thereby further improving the stamping quality of the metal sheet.
